Longicornia Malayana; or, a Descriptive Catalogue of the Species of the three Longicorn Families Lamiidæ, Cerambycidæ and Prionidæ, collected by Mr. A. R. WALLACE in the Malay Archipelago. By FRANCIS P. PASCOE, F.L.S., Pres. Ent. Soc.

THE large private collection of Longicornia formed by Mr. Wallace during his researches in the Malayan Archipelago having come into my possession, I have undertaken to describe all the species which it contains. Mr. W. Wilson Saunders, with his usual liberality, has offered to contribute towards the expense of the plates, and the Council of the Society has determined to publish the descriptions in a continuous form, so that the whole may be bound up eventually in one volume.

Until I have thoroughly gone through and described the whole of the collection I can only give an approximate estimate of its extent. There may probably be something less than a thousand species;* upwards of eight hundred of these may be calculated on as being new to science. With so great a number to be dealt

* I use the word "species" to embrace "all individuals having such a mutual resemblance between themselves as leads us to infer a common parentage." This definition certainly does not allow us to distinguish absolutely a variety from a species, but in the absence of positive certainty of the fact, I think it is always as well to treat as a species any marked departure from the ordinary form, until we have some proof of its specific identity.

with, it will be desirable to make some remarks on the classification, prefacing these, however, with a few words on the geographical distribution of the species and their relations to the same families belonging to the Indian and Australian faunas. Mr. Wallace himself will sum up the results and his views thereon at the conclusion of the work.

Our acquaintance with the Longicornia of the mainland of Asia is very imperfect. India, to judge from our collections, has generally a very meagre insect fauna; but the researches of the late M. Mouhot lead us to believe that a considerable proportion of Malayan Archipelago forms are to be found in Cambodia and Laos, but they probably do not extend in any numbers further north. The Longicornia of Australia are sufficiently well known to enable us to institute a comparison which, in its general results, can only lead us to one opinion, that is, the almost utter dissimilarity between them and those of New Guinea and, à fortiori, of the rest of the Archipelago.* Throughout this work I shall take every opportunity of contrasting the two, and shall not therefore dwell further on the subject at present, except to show, in the following table of ten of the largest genera of the Wallacean collection, the difference between the Malayan and the congeneric species, whenever they occur, of the Australian Longicornia.

* It is held that the western islands of the Malay Archipelago belong to the Indian region, and the eastern to the Australian. Mr. Wallace has asserted that this holds good in every branch of Zoology (Proc. Linn. Soc. 1860, Zool. iv. 172). "Borneo," he says, "is the counterpart of New Guinea," and "the Asiatic and Australian regions finding in Borneo and New Guinea respectively their highest development" (ibid. p. 174). On the whole I have not been struck by any special differences between the western and eastern portions of the Archipelago, so far as the Longicornia are concerned. Tmesisternus, the only exception I know, is apparently confined to the eastern portion, but the sub-family of which it is the type has representatives in Sumatra, Java, Singapore, &c., as well as in New Caledonia, the New Hebrides, New Zealand, Australia, the Fiji and other Pacific Islands. With regard to the Coleoptera generally, my impression is that there is a fair admixture of forms from Singapore to New Guinea, without any remarkable division between them anywhere; but that between the Australian and Malayan regions (including New Guinea) the difference, on the contrary, is really something marvellous.

[page] 3

It is probable that when the species of these genera come to be examined more carefully for description, a slight discrepancy may appear, but this may be more or less as regards numbers, and will not affect our conclusions. On the other hand, it is extremely probable that the number of Australian species belonging to the above genera will be increased.

It is unnecessary to go into the history of the classification of the Longicornia. Dr. Leconte, in the "Journal of the Academy of Natural Sciences of Philadelphia" (1849-51), was the first to put forward a really philosophical arrangement of them, but, unfortunately, his knowledge was almost entirely confined to the species found in North America. M. James Thomson, in his "Essai d'une Classification de la Famille de Cerambycides" (1860), has more fully carried out this system,* and at present this is the only work which treats of the whole of the genera of the Longicorn families.

If we must consider the Coleoptera to be entitled to no higher than ordinal rank, it will tend to simplify the classification if we call the Longicornia a "sub-order." Following Leconte, we shall then have the three families of Lamiidæ, Cerambycidæ and Prionidæ. These I propose to divide into "sub-families." We then come to the genera and species. If, for the sake of convenience, other divisions are required, it seems to me that it will be enough to constitute "sections," which may be numbered, but, to avoid confusion, not named.†

* Some excellent remarks by Mr. Bates on M. Thomson's work will be found in the "Annals and Magazine of Natural History," ser. 3, viii. 41 et seq. Mr. Bates thinks the position of the "Lepturitæ" as a group subordinate to the Cerambycidæ is untenable, but then he considers that the Disteniæ should form a "distinct tribe," and also that the "Pseudolepturitæ" of Thomson "will require probably the institution of one or more distinct tribes."

† The complicated ramifications into tribes, groups, races, cohorts, legions, branches, divisions, series, sections, and these again into sub-tribes, sub-groups, &c. &c., to say nothing of the "stirps" and the "phalanx," whose plurals in English I cannot venture to determine, all more or less employed in systematic works, and their application varying with every author, or even in the works of the same author, are such as to make zoological classification an affair of the most involved and indefinite character. It is frequently very difficult to ascertain what are equivalent groups, when we pass from one order or one author to another; the family of one author, for example, becomes the tribe, or the stirps, or the sub-family, or even the order of another. At one time the tribe precedes the family, generally it is subordinate to it; the same may be said of the stirps, the cohort, and the phalanx, &c. The confusion is sometimes increased by the application of names which are completely deceptive, such as Cuculinæ (a sub-family of cuckoos) to a group of bees, or indefinite names which are used in almost every class, such as "Aquatica" and "Longipedes." The sub-genus is another element of confusion. It would be very difficult to say what is the difference in the value between this and the genus. It often appears to be a sort of compromise put forward only until the author can make up his mind as to its real value, and, perhaps, as more likely to escape criticism in its more humble rank; but it has this inconvenience, that it is tantamount to giving two names, the sub-genus being adopted in one case and the genus in the other, both being sometimes used indifferently by the same author: or the sub-genus is inserted parenthetically, and then we have what amounts to a trinomial nomenclature.

[page] 4

LAMIIDÆ.

Dr. Leconte, taking various characters into account, considers that the Lamiidæ contain three series of forms; the first, "the typical Lamia series," attains its highest development in Sternotoma, Ceroplesis, Omacantha, and similar genera—to this he appends the "Saperdæ;" the second series is represented by the "Dorcadion form;" and the third by the "Acanthoderes or Ædilis form." But to these he was compelled to add a fourth series, "distinguished from all the others by the imperfection of the anterior acetabula." These four series were then divided into seventeen "groups." M. James Thomson ("Essai," &c.) adopts this arrangement almost entirely, but having far larger materials at his command, he has increased the number of divisions (using this word in a general sense) considerably. We still count seventeen "groupes," but the Dorcadion series containing no "groupe" is represented by two "divisions," a rank subordinate to the "groupe." Of the "groupes" ten stand alone; the remainder embrace eighteen "divisions," and four "sous-groupes." So that taking the "divisions" where there are no "groupes," and the "groupes" where there are no "divisions," and the "sous-groupes" where they occur without the "divisions," we have thirty-four subordinate forms, which we may consider take the place of the Lecontean "groups." There are also two "sous-divisions" in one of the "groupes:" these were probably intended to be "divisions;" if so, then we should have to add one more, which would bring the whole number of "groupes," and what are nearly equivalent to them, up to thirty-five.

Mr. Bates, in the work above quoted, is satisfied with dividing the Lamiidæ into six sub-tribes, remarking, however, that two of them might, perhaps, be further divided, and two

[page] 5

additional sub-tribes instituted. These are the "Hippopsitæ" from the "Oncideritæ," and the "Tapeinitæ" from the "Saperditæ." The two principal things that strike us in this arrangement are, first, that no provision has been made for the Dorcadion forms in any of these sub-tribes,—perhaps, because they do not occur in the Amazonian fauna,—and the second, the placing of the "Compsosomitæ" in the same sub-tribe with the "Desmiphoritæ," a position wholly unaccountable from anything I can gather in the description. Mr. Bates has not, however, overstated the case when he says, that "it is a matter of great difficulty, perhaps impossibility, to find constant characters for the subordinate divisions;" and therefore it must not be expected that systematists will always agree in their disposition of particular forms in a group so confessedly difficult as the Longicornia.

This difficulty arises from the great diversity of forms, and the gradual modifications of even the most important organs in nearly connected species, so that if we were to insist strictly on definitions, we should add almost indefinitely to the genera, and many of these again would have to be raised to the rank of sub-families. It frequently happens that we can only judge of the value of a character when we are able to follow it up into allied forms: an apparently excellent generic diagnosis, drawn from a single isolated species, may break down altogether when there are half-a-dozen to be dealt with; and in the case of higher groups than genera, we shall often find beyond its typical members a tendency only to the character which more than any other affects that particular group, or in other words the character becomes modified, or is lost altogether. In each of the sub-families of the Longicornia, I have noticed that there is generally one preeminent character, and other characters, that elsewhere were of primary importance, then become of secondary, or, perhaps, only of specific value. The absence of humeral angles and, consequently, of wings in the Dorcadion group, for instance, being of this special importance, we find other characters so subordinate as almost to startle us at meeting the most opposite of them in apparently nearly allied species.

In the arrangement of my collection, I have come to the conclusion, that there are at least twenty-four types among the Lamiidæ which can be clearly demonstrated. It is true, that in no case, after we have referred the various genera to their respective types, can any of them be distinguished by any absolute, much less by any series of characters, but by an examination of

[page] 6

each of these, as given in the definitions below, the tendency to gravitate to its proper type will be generally manifest in the combination of two or more of the characters, and the absence of others, in each genus. In cannot be denied, however, that there are a number of forms, which, place them as we may, will always be more or less anomalous members of the group to which they may be referred. And it may be added, that there are many genera whose location will depend in a great degree on the importance which some particular character may be thought to possess, and this importance may be modified at any time by the discovery of intermediate forms, so that we may be led to detect an affinity between genera, where previously we had no suspicions of any. Systematists, perhaps, allow themselves to be too much influenced by aberrant forms, and too readily disposed to regard them as types of distinct groups.

It is not to be supposed that these sub-families naturally follow each other exactly in the order they are placed below, but it will be readily understood that it is impossible to arrange them satisfactorily in a linear series. Saperdinæ, for instance, might follow Niphoninæ, Dorcadioninæ Lamiinæ, &c., but then this would break in upon other affinities of, perhaps, more importance. Tapeininæ is placed at the end because it is the most anomalous of all the sub-families; at the same time the Tmesisterninæ, being the transition group to the Cerambycidæ, might equally well terminate the series of the Lamiidæ. It is not improbable that some of the sub-families may be further divided with advantage—Anisocerus and allied genera from Acrocininæ, for instance;—and it may be doubted if the Lamiinæ can be maintained in their present entirety, but we have none of the former and very few of the latter in this collection.

NOTE.—Those sub-families which do not occur in the Wallacean Collection are bracketed.

ACANTHOCININÆ.

The well-known Acanthocinus ædilis and Leiopus nebulosus afford good examples of the more usual forms of this sub-family, which finds its greatest development in the tropical regions of the new world. The Acanthocininæ are distinguished from both Acanthoderinæ and Colobotheinæ (neither of which have exponents in this collection) by the short, often transverse, face; from the former also by the slender tarsi and antennæ, the elongate scape, and less robust body; and from the latter by the body more or less depressed, the prothorax toothed or angulated at the side, as well as by the scape and tarsi, which do not, however, afford quite so marked a contrast as they do with the Acanthoderinæ. Besides these characters, the Acanthocininæ have generally long and setaceous antennæ, arising from two diverging tubers, which have an impressed line between them, and the second joint is almost invariably two or three times longer than broad, never transverse; the eyes are reniform, often occupying a considerable portion of the head; the mandibles are feeble, and, when closed, generally pretty well covered by the lip; the elytra are frequently truncate or spinous at the apex; the anterior acetabula are entire, or only slightly angulated; the anterior and intermediate coxæ are globose and approximate at the base, with the pro- and meso-sterna simple and declivous; the femora are clavate; the fore-legs are never elongate in the males, although the posterior are occasionally, and their tarsi are scarcely dilated and never fringed; the claw-joint varies in size, generally, however, small; the three intermediate segments of the abdomen are always the shortest; the colour is mostly ashy or greyish varied with brown, and there are often setose hairs scattered among the pubescence. Many of the females have lengthened ovipositors.

Fourteen genera are in the collection, most of them very distinct; none of them, so far as I am aware, occur either on the mainland of Asia or in Australia.

This genus seems to be somewhat intermediate between Acan-

[page] 11

thocinus and Alphus, distinguished from the former (inter alia) by the absence of the lengthened ovipositor in the female, and from the latter in the greater length of the scape: in habit it is very distinct.

Acanista Alphoides. (Pl. I. fig. 3.)

A leviter grisescente-pubescens, albo-varia; antennis obscure annulatis.

Hab.—Mysol.

Thinly pubescent, dark greyish shading into white on each side of the prothorax and on the posterior half of the elytra, where also there is a pure white mark bent at an acute angle on each side towards the apex. Head narrower than the prothorax, slightly dilated below the eyes, the lip and epistome narrow; prothorax transverse, strongly spined at the sides, the anterior and posterior borders of equal breadth; scutellum rounded behind; elytra broader than the prothorax, depressed in the middle or somewhat concave, coarsely punctured, a line of small spines near the suture and several smaller ones at the shoulder, one also rather larger than the rest between the shoulder and scutellum, the apex truncate at the suture, then broadly emarginate externally, and ending in a long acute spine; body beneath with a pale greyish pubescence; legs obscurely annulated with greyish and white; antennæ about three and a half times as long as the body, the third and fourth joints with a very small spine at the apex.

Length 7 lines.

DRIOPEA.

Driopea, Pascoe, Trans. Ent. Soc. ser. 2, iv. 243.

Caput antice subquadratum, fronte convexo. Antennæ elongatæ, ciliatæ, scapo subcylindrico, articulo secundo brevi, cæteris subæqualibus. Prothorax lævis, subrotundatus, dente minuto laterali instructus, aliquando muticus. Elytra elongato-ovata, regularia, apice truncata vel emarginata. Pedes postici elongati, femoribus vix clavatis; tarsorum intermediorum et posticorum articulus basalis elongatus.

Of the more generally known genera of this sub-family, this genus is, perhaps, most nearly allied to Leiopus, but from which it is distinguished by its elongate posterior legs, truncate elytra, prothorax, and other characters. In coloration it resembles, like many more Indian genera, some of the species of Clytus.

[page] 12

Driopea Clytina.

Pascoe, l. c., p. 244; pl. xxv. fig. 2.

D. cinereo-pubescens, nigro-notata; prothorace utrinque dentato, cinereo; elytris subtrigonatis.

Hab.—Singapore.

Pubescence ashy, with patches of black; prothorax uniformly ashy; elytra with a black patch at the base extending more than half-way down the suture, the lower part expanding into a band directly across them, shoulder black, a triangular patch of the same colour on each side towards the apex. Head narrower than the prothorax, which is broader posteriorly, rounded at the sides, the tooth small but very decided; scutellum transverse, rounded behind; elytra broadest at the base, tapering very gradually to the apex, its outer angle spinous, the disc with several erect black setæ, the punctures hidden by the pubescence; body beneath, legs and antennæ with a fine greyish pile; antennæ about twice as long as the body.

Length 3½ lines.

Driopea inermis.

D. cinereo-pubescens, nigro-notata; prothorace mutico, disco nigro-biplagiato; elytris subangustatis.

Hab.—Dorey, Saylee, Waigiou, Morty, Batchian.

Pubescent, ashy with black patches; prothorax ashy, with two oblong patches on the disc; elytra with a semicircular patch at the base, an oblique patch on each side not meeting at the suture; directly below the middle a broad band, behind this and equidistant from the apex and close to the outer margin a smaller patch. Head scarcely narrower than the prothorax, which is very little broader behind and without a tooth at the side; scutellum not transverse, rounded behind; elytra oblong, rather narrow, with several rows of depressed black setæ, outer angle of the apex not spinous; body beneath, legs and antennæ dull fulvous, with obscure brownish patches and a thin greyish pubescence; antennæ about twice and a half as long as the body.

Length 3 ½ lines.

This species in some respects approaches Chydæopsis, but the more depressed body, style of coloration and form of the protibiæ are more characteristic of Driopea. The amount of black varies; on the upper portion of the elytra the patches are sometimes more or less confluent.

[page] 13

CHYDÆOPSIS.

Caput antice subquadratum, convexum. Antennæ elongatæ, vix ciliatæ, scapo subcylindrico, articulo 3° multo longiore, sequentibus attenuatis, fere æqualibus. Prothorax oblongus, regularis, lateribus vix rotundatis, muticis. Elytra angustata, gradatim attenuata, regularia, apice oblique truncata. Pedes intermedii et postici subelongati, tibiæ anticæ curvatæ; tarsorum intermediorum et posticorum articulus basalis valde elongatus.

Differs from Driopea in its narrower prothorax, not toothed at the side, in its body rather compressed than depressed, and in its shorter and curved protibiæ.

Chydæopsis fragilis. (Pl. I. fig. 1.)

C. cinerascente-pubescens, maculis elongatis fuscis; antennis pedibusque infuscatis.

Hab.—Sarawak.

Pubescence ashy grey, with two brown stripes on the disc of the prothorax, and a few oblong spots on the elytra, leaving, however, a band of ashy posteriorly, followed by another band of brown, the apex ashy. Eyes moderately large and prominent; head and prothorax nearly equal in breadth, the sides of the latter nearly parallel or only very slightly rounded; scutellum scutiform; elytra broadest at the base, much wider than the prothorax, with several lines of large coarse punctures; body beneath covered with a fine greyish pile; antennæ and legs brownish, distal half of the posterior and intermediate tibiæ ciliated; antennæ nearly three times as long as the body.

Length 3½ lines. "Taken on foliage."

POLIMETA.

Caput antice quadratum, convexum. Antennæ corpore longiores, ciliatæ, scapo subbreve, subfusiforme, articulo 3° longiore, 4—6 subæqualibus, sequentibus gradatim decrescentibus. Prothorax in utroque sexu vix elongatus, regularis, lateribus rotundatis, muticis. Elytra angustata, basi fere regularia, apice oblique truncata. Pedes postici subelongati, femoribus haud clavatis, tarsis intermediis et posticis articulo basali elongato.

The type of this genus is nearly allied to Ostedes, to which I had formerly referred it. The form of the prothorax, however, is so different as to necessitate its separation as a distinct group.

Polimeta spinosula. (Pl. I. fig. 4.)

Ostedes spinosula, Pascoe, Journ. of Entom. i. 62.

P. grisescens, fusco-variegata; elytris basin versus spinosis, spina incurva.

Hab.—Batchian, Amboyna, Morty, Dorey.

Finely pubescent, greyish varied with brown, the two principal patches of this colour being on the sides of the elytra. Head somewhat wider than the anterior margin of the prothorax, the latter a little longer than wide, with two nearly obsolete tubercles in front, anteriorly and posteriorly transversely sulcated; scutellum rounded behind; elytra narrow, the basal half sparingly punctured, a prominent, strongly-recurved spine on each towards but at some distance from the base, a few minute spines also at the base and sides; legs dark brown, more or less of the femora and basal half of the tibiæ reddish; body beneath reddish-brown; antennæ more than half as long again as the body, reddish varied with brown.

Length 4 lines.

A specimen from Ceram, much larger than the others, has also a somewhat broader prothorax. It may possibly be distinct.

Polimeta simplex.

P. grisescens, fusco-variegata; elytris muticis.

Hab.—Batchian, Ceram, Gilolo, Morty, Bouru, Dorey, Saylee.

Closely resembles the last, but there is no spine on the elytra, which are also less attenuated towards the apex, the sides, in other words, being more parallel; the scutellum is slightly pointed, and the anterior border of the prothorax is less strongly sulcated.

Length 3½ lines.

OSTEDES.

Ostedes, Pascoe, Trans. Ent. Soc., ser. 2, v. 43.

Caput exsertum, antice transversum, tuberibus antenniferis basi contiguis. Antennæ corpore longiores, ciliatæ, scapo subfusiformi, articulo secundo breve, 3° 4°que æqualibus, cæteris gradatim decrescentibus. Oculi prominuli, supra subapproximati. Prothorax maribus elongatus, feminis multo brevior, irregularis, utrinque fortiter angulatus. Elytra angustata, basi cristata et latiora, apice oblique truncata. Pedes postici subelongati, femoribus subclavatis.

This genus has not a very obvious affinity with any of the Acanthocininæ except the last, but the long basal joint of the

[page] 15

posterior and intermediate tarsi, and the nearly entire anterior acetabula, have determined me to refer it to this sub-family.

Ostedes pauperata.

Pascoe, l. c., p. 44; pl. ii. fig. 1.

O. cana vel grisea, fusco-notata vel maculata; antennis pedibusque annulatis.

Hab.—Sarawak, Macassar, Batchian, Morty, Bouru, Amboyna, Aru, Dorey.

Finely pubescent, with a few scattered setæ, especially between the eyes, pale ashy or greyish with patches of brown, sometimes with a few spots only. Head broader than the anterior border of the prothorax, slightly exserted; eyes rather large, prominent, sub-approximate on the vertex; prothorax of the male nearly twice as long as broad, with a very prominent angle rather beyond the middle, the disc with four spreading tubercles; scutellum rounded behind; elytra irregularly punctured, gradually diminishing from the shoulder to the apex, the base with a short mesial crest, tipped with a few setæ, the largest patches, when they occur, at the side behind the middle; body beneath brown, with a greyish pile; antennæ and legs ringed with greyish and brown, the former in both sexes about a third as long again as the body.

Length 6 lines.

The varieties of this species, as might be expected from its extended range, are numerous, but they are all too trifling for description, differing principally in the amount of coloration. Those from Morty are the darkest. The female has the prothorax scarcely longer than broad, and the angle is nearly in the middle.

EOPORIS.

Caput antice transversum, apice emarginatum, tuberibus antenniferis basi approximatis. Antennæ elongatæ, subciliatæ, scapo apicem versus constricto, articulo secundo brevissimo, tertio longiore, cæteris gradatim decrescentibus. Oculi prominuli. Prothorax sub-oblongus, vix irregularis, lateribus inermis. Elytra angustata, regularia, basi latiora, apice oblique truncata. Pedes elongati, femora clavata, basi attenuata, tarsorum intermediorum et posticorum articulo basali longissimo, articulo ultimo parvo.

A very distinct genus, remarkable for the broadly emarginated border of that part of the face just above the epistome. The form of the scape is also peculiar.

Eoporis elegans. (Pl. I. fig. 6.)

E. tenuiter pubescens, cervina, brunneo-variegata; antennis, tibiis, tarsisque testaceis.

Hab.—Singapore, Sarawak, Batchian, Macassar, Ceram, Dorey.

Thinly pubescent, pale cervine, very distinctly varied with fulvous brown, forming at the base and middle of the elytra two somewhat reticulated bands. Head slightly broader than the prothorax, rather narrower below the eyes, emarginate at the apex, the epistome and lip very short; prothorax somewhat oblong, slightly rounded at the sides; elytra gradually tapering from the base to the apex, but the sides very slightly rounded; femora strongly clavate, fulvous brown, their bases, tibiæ, tarsi and antennæ testaceous, the latter about three times as long as the body.

Length 5 lines.

PITHOMICTUS.

Caput antice rotundatum, linea impressa inter oculos obsoleta, tuberibus antenniferis approximatis. Oculi haud prominentes. Antennæ corpore parum longiores, scapo elongato, cylindrico, articulo tertio scapo fere æquali, cæteris gradatim brevioribus. Prothorax vix subtransversus, æquatus, lateribus rotundatus, spinosus. Elytra oblonga, apice truncata, extus spinosa. Pedes mediocres, femora modice clavata, tibiæ subattenuatæ; tarsi antici dilatati. Corpus paulo convexum.

There is no genus that approximates to this in the present collection. The Brazilian Probatius has much the same general outline and habit, but differs in the femora, tibiæ, and particularly in the tarsi, and in the antennæ. The coloration is much in the style of some of the Clyti.

Pithomictus decoratus. (Pl. II. fig. 1.)

P. prothorace pube aureo-grisea vestito; elytris nigris, basi, apice, et lineis duabus, suturam versus conjunctis, ante medium, griseis.

Hab.—Morty.

Head covered with a coarse grey tomentum, the front convex and rounded, the cheeks showing behind the eyes, no impressed line between the antennæ, but the antennary tubers well marked; eyes dark brown; prothorax convex, closely covered with a greyish pile tinged with yellow, scarcely so long as broad, rounded at the sides, with a small but well-marked spine placed a little behind the middle; scutellum nearly quadrate, a little broader

[page] 17

anteriorly; elytra very slightly rounded at the sides, seriate-punctate, the punctures small and distant, the apex truncate, terminating externally in a spine, black; the base with an ashy, broadly triangular band or blotch, which, however, is rounded at the point; behind this, but before the middle, two also ashy lines, the upper oblique, the lower transverse, which meeting near the suture dip down and become continuous with the other side, the whole of the apical region yellowish-grey, the division of colours between these markings very distinct and decided; body beneath black; legs and antennæ black, with a slight ashy pile.

Length 3 ¼ lines.

OPSIOLEUS.

Caput antice quadratum. Oculi supra subapproximati. Antennæ elongatæ, ciliatæ, scapo modice elongato, subfusiforme, articulis 3° 4°que longioribus, cæteris gradatim decrescentibus. Prothorax transversus, regularis; lateribus rotundatis, inermibus. Elytra oblonga, regularia, apice extus spinosa. Femora haud clavata, tibiæ elongatæ, tarsi breves.

Differs from Amniscus, Bates, to which it is allied, in its more slender femora and shorter scape, &c. It is a very obscure looking insect.

Opsioleus adversus. (Pl. II. fig. 7.)

O. griseo-cinereus, pubescens, maculis fuscis dispersis; antennis pedibusque fulvis, pube cinerea vestitis.

Hab.—Malacca.

Covered with a coarse greyish adpressed pile, interspersed with a few stiff black hairs, and faintly spotted, except on the elytra where the spots are much darker, with brown. Head rather narrower than the prothorax, which is considerably contracted anteriorly; scutellum transverse, rounded behind; elytra broader than the prothorax, the sides rounded, the broadest part at about the middle, not very narrow at the apex; the disc with scattered, large, shallow punctures; body beneath, antennæ and legs pale fulvous, with a thin greyish pile; antennæ about two-thirds as long again as the body.

Length 4 ½ lines.

MYNONEBRA.

Caput exsertum, subangustatum. Oculi majusculi. Antennæ validæ, ciliatæ, vix subelongatæ, scapo breviter fusiforme,

VOL. III. THIRD SERIES, PART I.—SEPT. 1864. C

[page] 18

articulo tertio elongato, sequentibus gradatim decrescentibus. Prothorax subquadratus, lateribus leviter rotundatis, pone medium spina brevi sed valida instructus. Elytra oblonga, apice vel rotundata vel truncata. Femora modice clavata; tarsi omnes articulis tribus basalibus simul triangularibus. Corpus pilosum.

From Ægocidnus this genus differs in its narrower head, stouter antennæ, and shortly fusiform scape; it is also a more robust form. Clodia has a sub-basal thoracic spine, and the head more deeply inserted in the thorax. The species, five in a number, are very homogeneous; their colour varies from light to dark brown, and is modified by a greyish pubescence, mixed with short, scattered erect hairs; the elytra sprinkled or spotted with white or ashy, and in all the head, prothorax, and elytra are strongly punctured; on the latter the punctures are arranged in irregular lines. The apex of the elytra is either rounded or truncate, but in this respect there is a certain gradation between the species.

Mynonebra diversa. (Pl. I. fig. 7.)

M. capite prothoraceque infuscatis; elytris brunneis, fere obsolete cinereo-maculatis, singulis plaga alba postica, apice rotundatis.

Hab.—Waigiou.

Head and prothorax light smoky brown, deeply and strongly punctured; mandibles black; palpi testaceous; elytra reddish-brown, slightly nitid, the central portion with a few scarcely perceptible ashy spots, while posteriorly there is a large well-marked white patch on each, and behind these patches they are mottled with greyish, apex rounded; body beneath dark luteous, subnitid, legs and antennæ luteous, the latter half as long again as the body.

M. griseo-brunnea; elytris singulis plagis duabus dilutioribus fere obsoletis, apice rotundatis.

Hab.—Mysol.

Dull greyish-brown; head and prothorax strongly punctured; mandibles luteous, darker externally; palpi testaceous; scutellum transversely triangular; each elytron with two almost imperceptible spots, one lateral and præmedian, the other between the middle and apex, which is rounded; body beneath chesnut-brown, subnitid; legs greyish-brown; antennæ luteous, a little longer than the body.

Length 4½ lines.

Mynonebra consputa.

with its external angle strongly marked; body beneath black with a thin grey pubescence; legs and antennæ brownish-luteous, the latter longer than the body.

Length 4½ lines.

CLODIA.

Caput fronte quadrato. Oculi antice distantes, supra subapproximati. Antennæ graciles, ciliatæ, basi valde remotæ, scapo breviter fusiforme, articulo tertio elongato, cæteris gradatim brevioribus. Prothorax brevis, spina subbasali instructus. Elytra oblonga, apice integra. Femora modice clavata. Tarsi breves, articulis tribus basalibus simul subtriangularibus.

This genus is distinguished from Mynonebra principally by its short prothorax, the more basal position of the lateral spine of the prothorax, and its more slender antennæ, and from Ægocidnus by its shorter and thicker scape, as well as by its more robust proportions.

Clodia sublineata. (Pl. I. fig. 8.)

C. luteo-brunnea, parce cinereo-pubescens; elytris lineis duabus subelevatis.

Hab.—Batchian.

Luteous brown, with a thin ashy pubescence; head narrower than the prothorax, but rather broad and a little convex in front, the eyes somewhat approximate above; prothorax slightly transverse, its surface regularly convex and strongly punctured, the spine short and triangular; scutellum transverse, rounded behind; elytra subseriate-punctate, gradually narrowing from the base, each with two very slightly raised longitudinal lines, the portion behind the middle somewhat raised towards the side, and sometimes abraded so as to show a patch of the derm; body beneath luteous, the last abdominal segment brown; legs and antennæ luteous, covered with a sparse pubescence, the latter about two-thirds longer than the body.

Length 4 lines.

OLMOTEGA.

Caput exsertum, fronte subquadrato. Oculi antice distantes. Antennæ setaceæ, ciliatæ, modice elongatæ, scapo subelongato, cylindrico; articulo tertio multo longiore, quarto breviore, cæteris gradatim decrescentibus. Prothorax sub-rotundatus, spina laterali minuta pone medium, disco

[page] 21

bituberculato. Elytra oblonga, interruptè carinata, apice truncata. Femora modice clavata. Tarsi postici et intermedii æquales, subelongati, articulis tribus ultimis simul triangularibus.

A very distinct genus, distinguished from the rest of its sub-family, in the present collection by the bituberculate disc of the prothorax, and by the rough and interrupted ridges of the elytra.

Olmotega cinerascens. (Pl. I. fig. 5.)

O. tenuiter cinerascente - pubescens; tibiis infra tarsisque nigris.

Hab.—Kaioa.

Covered with a thin ashy pubescence; head coarsely punctured in front, the vertex slightly rising behind; prothorax broader than the head, with a somewhat rounded outline, coarsely punctured, the two discal tubercles nearly in the middle, the lateral spine very small, but distinct; scutellum rounded behind; elytra irregularly seriate-punctate, three interrupted ridges on each, the inner raised into a tritubercular crest at the base, re-appearing behind the middle, the second commencing at the shoulder, terminating gradually at about the middle, the outer at the side, more produced towards the apex; body beneath dull ashy; legs ashy, the tips of the tibiæ and the tarsi black; antennæ about a third longer than the body, luteous, with a thin ashy pile, the distal joints darker at the tips.

Length 4 lines.

PHYXIUM.

Caput parvum, vertice elevatum, tuberibus antenniferis robustis. Oculi majusculi, in vertice subapproximati. Antennæ setaceæ, vix ciliatæ; scapo subelongato; articulo tertio longiore, cæteris gradatim decrescentibus. Prothorax transversus, lateribus basin versus fortiter spinosus. Elytra lata, pone humeros constricta, lateribus angulata vel subito deflexa, basi carinata, apice rotundata. Femora brevia, fortiter clavata. Tarsi antici articulis transversis, intermedii et postici (ultimo excepto) subæquales. Prosternum triangulare, postice subelevatum.

This is a remarkable genus, resembling the Brazilian Onychocerus in outline. In the irregular surface of the prothorax and elytra it approaches Olmotega, but is otherwise very distinct. There are three well-marked species; in these the pubescence is

[page] 22

somewhat scaly, and the punctures on the elytra are large, and have at the base a little compact circle of scales, which gives a ringed appearance to each puncture.

Phyxium bufonium. (Pl. II. fig. 3.)

P. griseo-album, punctis fuscis præsertim prothorace dispersum; prothoracis disco bituberculato; antennis annulatis.

Hab.—Batchian.

A pale honey-yellow derm, covered, especially on the elytra, with very small, white, not very closely set, scales. Head much narrower than the prothorax, even at the apex, the vertex considerably raised above the eyes; prothorax twice as broad as long, the disc between the tubercles with coarse, closely-set punctures, which are pitchy-brown internally, giving that part of the prothorax a much darker appearance than the sides, which are more densely pubescent; scutellum dark brown, very transverse, and contracted at the base; elytra very much broader than the prothorax, especially at the base, coarsely punctured in somewhat irregular lines, the basal ridge very short, dark brown, behind this two oblique slightly elevated stripes of the same colour, one in the middle, the other towards the apex, the side bent down at a right angle, forming, from the shoulder to near half the length of the elytra, a sharp well-defined ridge; posterior margin and apex fringed with longish, curved, white hairs; body beneath and legs covered with a greyish pile, the tibiæ also fringed with long hairs; antennæ half as long again as the body, very pale, the apex of the third joint, and of all the succeeding, dark brown, the last four or five becoming gradually entirely brown, except at the base.

Length 3 lines.

Phyxium scorpioides.

P. fuscum, elytris dilutioribus; prothorace utrinque griseo; antennis luteo-fuscis.

Hab.—Aru.

Dark brown, mixed with a little grey on the elytra; front of the head, and especially the sides of the prothorax, more strongly marked with the same colour. Head much narrower than the prothorax, the latter nearly twice as broad as long, the disc with two large but not very elevated tubercles, the sides considerably contracted at the base behind the spine, which is short and toothlike; scutellum scutiform; elytra much broader than the prothorax,

[page] 23

sharply ridged at the base, with two or three slighter ridges on the same line, the side bent down but not angulated except at the shoulder, the margins towards the apex fringed with stiff hairs; body beneath brown, with scattered greyish hairs; legs with longish grey hairs; antennæ luteous brown, with greyish hairs.

Length 3½ lines.

Phyxium ignarum.

P. grisescente-fuscum; prothorace toto griseo-pubescente; antennis brunneis, articulorum apicem versus gradatim infuscatis.

Hab.—Mysol.

Much narrower in proportion than the last, dark reddish-brown with a very thin greyish pile. Head small, considerably narrower than the prothorax, which is nearly twice as broad as long, both closely, and the latter also coarsely punctured, with the greyish pile pretty equally distributed over the surface; elytra scarcely dilated posteriorly, as in the two preceding species, with very coarse punctures arranged in irregular rows, the ridge at the base very slightly elevated and extending to about the middle of the elytron, the side scarcely angulated, but the interval between the two rows of punctures at that part somewhat raised; body beneath pitchy-brown, with a scattered pile principally on the breast; legs reddish-brown, covered with a greyish pile; antennæ pale reddish-brown, the apex of the third joint and all the succeeding joints becoming more and more tinted with dark brown.

Length 2¼ lines.

ACALOLEPTA.

Acalolepta, Pascoe, Trans. Ent. Soc., ser. 2, iv. 247.

Caput exsertum, antice quadratum. Oculi parvi, in vertice non visi. Antennæ nudæ, longissimæ, basi distantes; scapo brevi, subcylindrico; articulo tertio duplo longiore, sequentibus, ultimo excepto, gradatim decrescentibus, ultimo elongato. Prothorax quadratus, utrinque dentatus. Elytra subangusta, apice rotundata. Femora modice clavata; tarsi omnes æquales, articulis tribus basalibus simul subtriangularibus.

The only species of this genus has the aspect of a small Monochamus. The antennæ, however, distant at the base, the short scape and clavate femora, among other characters, separate it from that group. The equal or nearly equal length of all the tarsi, and the peculiar form of the eye, will, one or the other, distinguish it from the other genera of this sub-family. The anterior acetabula are angulated externally.

[page] 24

Acalolepta pusio.

Pascoe, l. c., pl. xxv. fig. 4.

A. parce pubescens, obscure brunnea; antennis pedibusque dilutioribus, illis articulis apice infuscatis.

Hab.—Sarawak.

Pale brown, with a sparse greyish pubescence, combining to give the surface a dull brownish tint. Prothorax scarcely broader than the head, rather closely punctured, the small tooth-like spine behind the middle; scutellum rounded behind; elytra coarsely punctured, the punctures in irregular rather distant lines; body beneath with a thin greyish pubescence; legs and antennæ paler, the latter three times as long as the body, the tips of the latter more or less darker, except the last, which is only dark at the base.

Length 3 lines.

ÆSCHOPALÆA.

Caput exsertum. Oculi lobo superiore obsoleto. Antennæ elongatæ, subciliatæ, basi approximatæ; scapo brevi, subpyriforme; articulis tertio ad decimum subæqualibus, ultimo cæteris longiore. Prothorax oblongus, vel suboblongus, lateribus angulatus. Elytra subangusta, apice rotundata. Femora clavata, tibiæ anticæ curvatæ, tarsi subbreves, articulo primo secundo æquali.

In the habit, approximate or subapproximate antennæ, and the greater length of the terminal joint, this genus resembles Monochamus, Serv., but the clavate femora and short subpyriform scape exclude it from any connexion with that group. In the character of the terminal joint of the antennæ and in habit Æschopalæa agrees with Acalolepta. The eyes in both are remarkable; the upper lobe terminates behind the antennary tuber and not above it, so that when these organs are thrown back nothing of the eyes is seen on the vertex. The scape is pyriform, but owing to a greater contraction on the upper side it has a sort of oblique appearance. The head, including the eyes, is rather roundish in front, but a little pinched up below the tubers, and is about as broad as the prothorax; this latter organ is considerably narrower than the elytra in all except Æ. laticollis.

Æschopalæa agraria. (Pl. I. fig. 2.)

Æ. grisescente-brunnea, elytrorum apicem versus pallidior; prothorace magis longiore quam latiore; elytris ab humeris gradatim angustioribus.

Hab.—Ceram.

Reddish-brown, gradually becoming paler from the base to the

[page] 25

apex of the elytra, and covered with a delicate greyish pubescence, which scarcely obscures the colour of the derm as in the other species. Head about as broad as the prothorax, the latter about a fifth longer than broad, and remotely punctured, the angle at the side almost resembling a spine; scutellum transversely quadrangular; elytra gradually narrower from the base to the rounded apex, with somewhat coarse scattered punctures; body beneath and legs covered with a greyish pile; antennæ about two and a half times as long as the body, pale reddish-brown.

Length 4 lines.

Æschopalæa tomentosa.

Æ. fere tota grisea; prothorace vix longiore quam latiore; elytris lateribus parallelis.

Hab.—Singapore, Macassar.

Entirely covered with a rough greyish pubescence except over the numerous punctures; these are much larger and more closely placed than in the last; the prothorax is nearly equal in length and breadth if the angles be included, and the antennæ are perceptibly finer, especially towards the apex.

Length 3½ lines.

Æschopalæa grisella.

Æ. angustior, pallide grisea; prothorace vix longiore quam latiore; elytris lateribus fere parallelis.

Hab.—Aru.

Narrower than the last, but also covered with a greyish pubescence, paler and thinner, however, and somewhat ragged in its dispersion, with punctures smaller and more scattered; the tarsi more slender, and the antennæ scarcely twice as long as the body.

Length 3 lines.

Æschopalæa laticollis.

Æ. grisea; prothorace latiore, vel haud longiore quam latiore, elytrorum basi fere æquale.

Hab.—Mysol.

Stouter in all its parts than the three preceding, and covered with a coarse greyish pubescence, interrupted over the punctures, these are smaller than in Æ. tomentosa, but are equally crowded, and the prothorax, including the angles, is nearly as wide as are the elytra at the base, and is, perhaps, a trifle broader than it is long; antennæ rather more than twice as long as the body.

Length 3—4 lines.

[page] 26

EXOCENTRINÆ.

This sub-family is very nearly allied to the last; indeed, latterly, authors have not made any distinction between them. M. Mulsant, who, first proposed the sub-family or "Branche," as he termed it, under the name of "Pogonochéraires," only mentioned the three genera Pogonocherus, Exocentrus and Stenidea. M. Thomson places the first and last of these in his sixth "Groupe Saperditæ," Exocentrus taking its place in the second "Groupe Acanthocinitæ," with two or three other genera which I refer to this sub-family. M. Thomson is probably right in the position he assigns to Stenidea, but I think Pogonochærus cannot be put far from Exocentrus, and as the latter is the most typical of the two it would be more appropriate to take its name for the sub-family.

The Exocentrinæ have the face convex or rounded, generally short and transverse; the antennary tubers pretty far apart, so as only to leave the usual mesial line, with very little tendency to depression between them: the eyes are small or of moderate size, deeply and widely emarginate; the mandibles rather feeble and without teeth, and the palpi are pointed. The antennæ are variable, but they are never so long as in many of the preceding sub-family; very often the joints are short and thick, or even tumid, almost always with a fringe of stiffish hairs beneath, or the whole of those organs is more or less hairy. The prothorax is generally armed at the side with a short spine, which is often placed near the base; in some genera this part shows a remarkable tendency to arching or curving upwards above the level of the elytra, and the disc is occasionally armed with two spines. The elytra are more or less oblong, with the apex entire, at least so far as the species of this collection are concerned. The legs are of moderate length, the femora always clavate, the intermediate tibiæ emarginate, and the tarsi never elongate; the anterior coxæ are large and standing well out of their acetabula, and these latter are either entire or angulated. The species are all of small size, rather depressed and very often clothed with long erect hairs, which are sometimes stiff enough to be called "setæ." They are found in all parts of the the world, and are represented in Australia by the genera Pentacosmia, Newm., and Ameipsis, Pasc. (each of one species only), and Exocentrus erineus, Pasc.; in New Zealand, by the Lamia crista, Fab.; but there can be no doubt that these numbers will be considerably increased when the insects of those countries shall be better known. In the present collection we have twenty-two genera and and forty-nine species.

The differences between the two common European forms of this genus (E. balteatus and E. adspersus) render it difficult to draw up a very decided diagnosis of it, yet at the same time no one doubts that they are congeneric. The species described below, except E. mœrens, in the form of the prothorax are most allied to E. adspersus. I have formed a section apart of E. mœrens, as the small prothorax, not broader than the head, although transverse as in the others, appears to indicate something beyond a specific difference, but, on the other hand, the prothorax of E. balteatus seems pretty nearly intermediate.

Section 1.—Prothorax much broader than long; the spine bent back nearly in a line with the body:—E. hispidulus, Pasc.; E. centenes, n. s.; E. lachrymosus, n. s.; E. echimys, n. s.

Section 2.—Prothorax scarcely broader than long; the spine smaller, directed obliquely backwards:—E. mœrens, n. s.

It is with some hesitation that I propose to separate the species

[page] 31

described below from Exocentrus, which, having a wide geographical range, may be expected to present a considerable amount of variation. However, the narrower head, the more slender antennæ, with the greater length of the third and fourth joints when compared with the scape, the absence of setæ, and a difference of coloration, would seem, taken together, sufficiently distinctive characters, were it not that there are indications that the most important of them, i.e. those of the antennæ, may prove to be too variable for generic use. Thus in S. melanotis, for instance, the fourth joint is considerably shorter than the third, while it is longer in S. mutatus, and about equal in S. suffusus. This shading away of characters is, unfortunately for the systematist, more the rule than the exception in the Longicorn families.

The long and slender antennæ shut this genus out from the genuine Exocentri, with which I had formerly arranged it. It may be remarked that the femora are more clavate, and the slender basal portion so lengthened that it is seen from above. The single species upon which the genus is founded is remarkable for the long hooked spine of the thorax, which is also slightly bifid at the point of its greatest convexity.

The seven species here brought together form a very natural group, allied to Ægocidnus (post, p. 40), which, however, is a narrower form, without setæ, and with more clavate femora. They are all below the average size, one only attaining to the length of two lines and three quarters; the punctures on the head and thorax are minute and very closely placed, those on the elytra are coarser and have to a certain extent a linear arrangement.

The dilated anterior tarsi of the males, the lengthened meta-

D 2

[page] 36

sternum, and the more than usually broad outline, are the principal characters of this genus. In consequence of the elongation of the metasternum, the posterior legs are so far removed from the intermediate that the femora, although comparatively short, extend nearly to the extremity of the elytra, especially in the males. The anterior acetabula are slightly angulated externally.

Head mostly ashy grey, eyes small; mandibles black; palpi luteous; prothorax much broader than the head, ovate-oblong, the sides strongly rounded, and furnished behind the middle with a short slender spine, posterior to which is a large white patch, the disc also with a few obscure ashy spots; scutellum subscutiform, rounded behind; elytra broadest at the base, where it considerably exceeds the prothorax, gradually diminishing towards the apex, the sides slightly rounded, the disk speckled with ashy and spotted with white, the largest spot at the side before the middle, two in a line towards the apex and nearer the suture, and one outside the anterior of the two; body beneath ashy, the abdomen and legs dark brown, thinly pubescent, the posterior tibiæ whitish, the extremity and tarsi black; antennæ scarcely half as long again as the body, dull ashy, the apices of the intermediate joints passing into brown, the scape slightly tinged with rufous.

There is some variation in size and in form and number of spots in my specimens, but nothing sufficiently decisive to warrant their separation.

MYROMEUS.

There are no salient characters in this genus; nevertheless I have been unable to refer the solitary species it contains to any other, nor does it seem to have any very near ally; but the form of the scape, the position of the lateral spine, the presence of

[page] 37

numerous setæ, and the coloration, induce me to place it after Ipochira.

Prothorax subtransversus, utrinque rotundatus, spinis tribus instructus, basi apice latiore. Elytra oblonga, integra. Femora modice clavata; tarsi antici subtriangulares, postici vix subelongati.

The single species composing this genus has very much the appearance of Miænia irrorata (post, p. 39); the elytra are more parallel than in the Exocentri, and the antennæ are rather linear than setaceous; it is particularly distinguished from all the genera of the sub-family by the three spines of its prothorax.

[page] 38

three spines, the first at about the middle, the second longest and very slightly directed backwards, the posterior midway between the second and the base; scutellum rounded behind, covered with a rather close greyish pile; elytra coarsely seriate-punctate, oblong, their sides parallel, with several obolong, pale greyish spots in lines; body beneath reddish-brown; legs darkish brown; antennæ about half as long again as the body, dark brown, the scape paler.

Prothorax subtransversus, lateribus linea irregulari dentata instructus. Elytra oblonga, apice integra. Femora clavata, tarsorum articulo basali breviter triangulari; tarsi antici lati. Corpus setosum.

The irregular toothed line on the side of the prothorax will at once distinguish this genus, which is also remarkable for the broad anterior tarsi, a character, however, probably confined to the males. (It has not been sufficiently rendered in the Plate.)

Prothorax subtransversus, lateribus rotundatis, spina basin versus instructus. Elytra oblonga, integra. Femora clavata. Tarsi antici triangulares, intermedii et postici angustati, vix subelongati. Corpus haud setosum.

The unusual length of the third and fourth antennal joints (bringing the fifth to the apex of the elytra) is the principal character of this genus, which, in other respects, approaches Ægocidnus (post, p. 40), except that the pubescence is opaque and not silvery. The two species differ principally in colour, but the scutellum of M. marmorea is very decidedly transverse.

Length 2 lines.

The following species differs from Miænia in having the antennæ considerably shorter, although the third and fourth

[page] 40

joints are still beyond the usual length, the sixth reaching to the apex of the elytra; the body is also narrower and less depressed, and the scape, notwithstanding the shorter antennæ, is very decidedly longer, and more cylindrical.

Elytra anguste oblonga. Femora valde clavata; tarsi breves, postice angustati, articulo ultimo cæteris breviore. Corpus haud setosum.

A Leiopus-looking form, but narrower, with shorter tarsi, and a more median thoracic spine. Some of the obscurer species of Exocentrus (ante, p. 28) bear a marked resemblance to Ægocidnus, but they have less clavate femora and stouter antennæ. The species of this genus are clothed with a sort of silvery-greyish pubescence, having, however, at the side of each elytron, near the middle, a large bare patch; the head and prothorax are very minutely and closely punctured, but, except in Æ. juvencus, the punctures are tolerably well marked on the elytra.

This species closely resembles the last and may be only a local variety, but the central line of the prothorax is strongly marked and the lateral patches are less so; the elytra, except the patch at the side, are nearly unicolorous, or only slightly mottled from abrasion, and the eyes are light reddish-brown.

The prothorax is shorter, or rather, perhaps, proportionally narrower, than in the two former species, and in the most perfect of my specimens there is a decided, although interrupted, median line on that part; the elytra are perhaps uniformly grey, but, from abrasion, there are irregular dashes of reddish-brown in the above specimen; in another specimen the pubescence is nearly obliterated and the elytra have a reddish-brown hue, clouded with darker brown.

The difference between this species and Æ. grammicus is comparatively slight: it consists chiefly in this, that the two principal lines are slightly elevated between the rows of punctures, and the spaces between these are scarcely pubescent, and there are no

definite patches such as we see in Æ. grammicus. The legs also are unicolorous.

This genus offers the singular character of a deeply emarginate posterior tibia: this is the more marked, as the tibia just above the emargination forms a very strong angle or tooth; the intermediate tibiæ are also deeply emarginate. The genus is also peculiarly distinct in its ribbed elytra, or rather the intervals between the striæ form elevated lines, which at the base are particularly prominent.

ATHYLIA.

Elytra oblonga. Pedes breves; femora modice clavata; tarsi breves, articulo ultimo cæteris simul longiore. Corpus setosum.

This is one of those genera which, from the shortness of the legs and the thickness of the antennæ, seem to connect the Apomecyninæ with the Exocentrinæ. In fact it strongly resembles the North American Eupogonius, which, on account of its entire mesotibiæ, we refer to the former sub-family; on the other hand, Athylia has angulated anterior acetabula; this character is, however, as we have already seen, not a very reliable one. On the whole, taking also into consideration the large and prominent anterior coxæ, and the undoubted connexion that exists between this genus and many other genera of the sub-family, we have little hesitation in referring it here.

Prothorax transversus, post medium spinosus. Elytra oblongo-ovata. Femora subclavata, tibiæ anticæ subcurvatæ; tarsi breves, articulo ultimo elongato. Corpus setosum.

This is the first of those remarkable genera, of which there are several in this sub-family, which exhibits that curious form of antennal joint which I have just sought to describe by the term

[page] 44

"ventricose," that is, a joint gradually swelling out to the middle, but only on one side. As ususal, there are gradations even in the same antenna, and the form also appears to pass into the obconical joint we see in Ebæides. The type of this genus bears a strong general resemblance to Callia, the members of which group are also found to imitate various species of the Gallerucidæ. The thoracic spine is well marked, and directed obliquely backwards; the prothorax behind it curving inwards to the base. The protibiæ are slightly curved, a character which finds its greatest development in Ebæides. The anterior acetabula are strongly angulated in this genus, especially in C. tristis.

Closely allied to the last, but the yellow of the head and prothorax is darker and duller; the elytra are quite black, only slightly shining, the punctures more crowded and more impressed, so as to leave more the appearance of lines between them, and the prothorax is proportionally smaller when contrasted with the head.

GYARITUS.

Gyaritus, Pascoe, Trans. Ent. soc. ser. 2, iv. 244.

Caput antice quadratum, tuberibus antenniferis nullis. Oculi late emarginati.

Corpus setosum.

So far we have been dealing with genera with simple elytra; in this and Axinyllium these organs have a curved elevated spine at the base of each, and behind the spines the elytra are more or less depressed. This depression attains its maximum in the genus Oloessa, a remarkable form, which, as the most aberrant genus of the group, I have placed at the end. In the three genera there is also an arching, more or less, of the prothorax and head; this is the most decided in Oloessa. These peculiarities would almost seem to indicate another type of form, but from what I have said above, it will be seen how graduated are these modifications, and how difficult it is to use them satisfactorily as a means of classification. In G. hamatus the anterior acetabula are entire.

This is one of the very few genera of Lamiidæ, the only one, so far as I know, in this sub-family, having securiform palpi;* in other respects it is allied to Gyaritus, except that the antennæ are more slender, and the joints are not swollen at their tips. A single specimen was found by Mr. Wallace under a fallen tree.

The members of this genus have the look of the smaller species of Leiopus, differing however from that group (inter alia) in the unarmed prothorax, and the short basal joint of the posterior tarsi. The third species I have added with some slight hesitation, as it has a considerably shorter scape, a consideration of some importance in the classification of these mostly commonplace little animals. They have all, however, the second joint unusually long.

* In Phantasis, Thoms., one of the African Dorcadioninæ, the palpi vary from obtusely ovate to securiform.

The comparatively short thick scape and the form of the antennary joints, together with the long erect hairs which are dispersed over every part of the insect, point to the Exocentrinæ, notwithstanding there are a few minor characters, such as the unarmed prothorax, which seem to indicate an affinity with the Saperdinæ.

This genus resembles Ebæides (post, p. 51) in habit as well as in most of its other characters, only the prothorax is without impressed lines, and the antennæ are of the normal form, and the antennary tubers have disappeared. The single individual upon which it is founded was taken by Mr. Wallace "on a leaf, with its antennæ and legs stretched out."

Among the genera with the prothorax unarmed belonging to this sub-family, this will be distinguished by the third antennal joint being shorter than the scape, the nearly equal length of the

remainder, and the thickness generally of the antennæ. The genus is also very distinct in its coloration.

Corpus setosum.

The remarkable thickness of the antennæ in this genus, especially of the third, fourth and fifth joints, attains its greatest development in E. monstrosa, but it is scarcely less so in the other species. I do not recollect any other Lamioid genus in which the scape is not the thickest of the antennal joints. On the other hand, the last joint is very small, and in three of the species, if the character be not a sexual one, disappears altogether, the tenth joint being then nearly as small as the eleventh is in the other species. The anterior tibiæ are short and curiously bowed, and this is sometimes the case also with the intermediate and posterior, only in a less degree. As usual in this sub-family the pubescence is very short and much thinner on, or very nearly absent from, the head and prothorax; and the punctuation on those parts is scarcely visible,

even with a good lens. The joints of the antennæ are, however, very rugosely punctured.

This genus has quite the habit of Ebæides, from which I thought at one time that it would be unnecessary to separate it, but the peculiar structure of the antennæ of this genus, and the different form of the scape, preclude a sufficiently clear definition of the two groups if they were kept together. The comparatively short thick scape, contracted at the apex, will distinguish Dyemus from Enispia (ante, p. 50), from which it also differs in habit and coloration.

In the form and length of the scape this genus is almost exceptional in its sub-family, and it is quite so in its divided eyes. It has, however, the arched thorax of Ebæides and the elytra of Gyaritus; and what is more remarkable, it is so closely allied to the North American genus Cyrtinus, Lec.* (Clytus pygmæus, Hald.), that except in the antennæ and eyes I scarcely see how it differs. In both the femora are extremely attenuated at the base, then suddenly dilated, especially on the upper edge. The species upon which the genus is founded is one of the smallest of the Lamiidæ, scarcely exceeding a line in length.

* Dr. Leconte places this genus with the Dorcadions! Three very anomalous genera, Microplia, Serv. (Leptoplia, Dej.), Omosarotes, Pasc., and Scopadus, Pasc. (all South American) should also, I think, be placed near the above. The first of these has the long scape, attenuated at the base, and gradually enlarging upwards, of Oloessa; the last two have the "Cyrtinine" profile in perfection, while in Microplia it is only just beginning to develope itself, as in the case of Gyaritus, but after another type.

The principal characters of this sub-family, which very nearly corresponds with the "groupe Oncideritæ" of M. J. Thomson,† are the large claw-joint and the ovate or shortly clavate scape. This last character has not hitherto been noticed, I believe, but it separates this sub-family from the Mesosinæ, which have a long cylindrical scape. The greater part of the genera, although frequently composed individually of what may be termed "fine" species, are generally of a rather commonplace appearance, and they are, as might be expected, very difficult to limit.

The Niphoninæ have mostly a moderate-sized ovate head, more or less transverse or subquadrate anteriorly,—that is, from the vertex to the line of the insertion of the epistome,—or it is very large, flat or rounded in front, as in Abryna, Oncideres,‡ and other genera. The antennary tubers commence near the eye, or sometimes arise near the mesial line when they become approximate at the base; they are cornuted in the males of Oncideres. The eyes are almost invariably of moderate size and deeply emarginate.

* This is not correctly represented in the profile figure.

† Of the "Essai," not of the "Syst. Cerambyc."

‡ This genus, although a very natural one, is most variable in its characters.

[page] 57

The antennæ vary from two or three times the length of, to a little shorter than the body, the terminal joint is frequently hooked at the point, but the scape is always short, or comparatively so, and ovate or slightly clavate, except in some species of Oncideres. The prothorax is usually subtransverse, unarmed at the sides, but having instead one or frequently two short tuberculiform teeth near its anterior border. The elytra are oblong or ovate, with a tendency to develope into crests or elevated lines at the base, or to throw out little granules, which are almost invariably black and glossy. The legs are of moderate length (except in many cases the fore-legs of the males), and robust; the thighs more or less clavate, never linear. The tarsi are nearly all of equal length, more or less trigonate, with the claw-joint as long as the three basal taken together. The anterior coxæ of the males are often armed with a recurved spine, occasionally of a formidable length, as in Ischioplites metutus and Xiphotheata Saundersii. The prosternum is invariably elevated to a level with the coxæ, except in Oncideres, and this is often met by a corresponding elevation of the mesosternum, so that the power of the insect in bending is considerably reduced. The three intermediate abdominal segments are the shortest; in a few species, however, the second segment is of greater length, and is then covered, more or less, with a semicircular patch of very densely set erect hairs.

In this great sub-family Europe is represented by only a single species (Niphona picticornis). Oncideres, numerous in species, and other genera, abound in South America. Africa yields Hecyra, Dichostates, Diastocera, and a few other genera not containing many species. In Australia we have numerous species of Symphyletes, Rhytiphora, Penthea, &c. From Asia we know of no genus peculiar to it, and very few species. In the Wallacean Collection we find eighteen genera and fifty-seven species.

The characters that have been used in the following table are mostly of a secondary nature, but they are the most obvious so far as the species treated of here are concerned.

Antennæ corpore longiores, setaceæ, ciliatæ; scapo oblongo-ovato, articulo quarto tertio longiore, cæteris brevioribus et subæqualibus, ultimo apice curvato. Prothorax latus, subtransversus, rugosus, disco depresso, dentibus duobus validis. Elytra oblongo-ovata, convexa, regularia, apice integra.

A broader and more robust form than Niphona, the prothorax more convex and even, the sterna more produced, the fore-legs of the males elongate, and their femora larger than those of the intermediate and posterior legs. From Axiothea it differs in the unbroken surface of the prothorax and elytra. The species, and even individuals, vary greatly in size, and owing to the monotonous repetitions of nearly the same sombre and indistinct colours, are difficult to determine as well as to describe.

Pedes antici robustiores, intermedii quam postici longiores. Pro- et mesosterna elevata.

The species comprised in this genus have a narrower and less bulky figure than most of the other species belonging to this sub-family. This is principally owing to the more trigonate elytra, which are also more depressed at the base, and without any carinæ or crests. The longitudinal line, more or less elevated, on the prothorax is smooth and without pubescence, and has therefore a more marked appearance, which with the subtrigonate elytra contribute to give the genus a character distinct from its

F 2

allies. Individuals vary considerably in the extent and depth of colour at the base of the posterior margin of the prothorax in all the species; there is a little depressed point on each side of the scutellum, free from pubescence, but in one individual of A. jubata there is no trace of this point.

ESCHARODES.

Caput mediocre, antice transversum, tuberibus antenniferis validis. Oculi parvi, profunde emarginati. Antennæ corpore longiores, validæ, setaceæ, maculis pubescentibus vestitæ, vix ciliatæ; scapo brevi, subclavato, articulis tertio quartoque magis longioribus, cæteris subæqualibus, ultimo apice curvato. Prothorax capite multo latior, longitudine latitudini æqualis, utrinque tumidus, carina longitudinali medio instructus, lateribus antice bidentatus. Elytra irregularia, granulifera, basi latiora, lateribus sensim decrescentia, apice truncata. Prosternum postice dentatum. Mesosternum parvum, elevato-dentatum, postice bifidum. Coxæ anticæ maribus spina brevi recurva. Pedes validi, antici maribus subelongati; protibiæ rectæ; tarsi breves, articulo penultimo latiori.

The strongly marked mesial ridge on the prothorax will distinguish this genus from Axiothea (post, p. 72), to which it is nearly allied, but from which it also differs in the form of its prothorax, elytra, protibiæ, and the presence of spines on the anterior coxæ of the males. I have been very much puzzled with the first two species. No two congeneric forms can apparently be more distinct, but then intervening forms occur, which, with the exception of the mesial ridge (and not always then), offer scarcely any definite characters. Even the tooth on the anterior femora is absent in one specimen which there can be no hesitation in placing with E. carinicollis; and there are others where the description given for that species has only a partial application, varying more or less in each: these remarks are purposely confined to the males. Nevertheless (and subject to this explanation) I think it will be better to furnish the two forms with distinctive appellations. They appear to be very common where they occur, and the two will doubtless be found very difficult to separate. The colour varies from grey to pale ashy, which is more or less extended at the expense of the brown, and this sometimes, at least in E. carinicollis,

[page] 71

depends almost entirely on the amount of pubescence covering the derm.

I have already (p. 70) pointed out in what respects this genus differs from Escharodes, its nearest ally. The first described species differs very much in the depth of its colours, the dark brown being replaced by light brown, and this again by grey, the median patch only showing feebly. With regard to A. distincta, its colour is also variable, but it may be readily distinguished from A. strenua by the smaller and more scattered granules. Axiothea invida is characterized by a well-marked basal crest on each elytron; in the first two species it is little more than a raised line. This also appears to be very variable as to colour.

Axiothea strenua.

Hab.—Amboyna, Batchian, Morty, Mysol, Kaioa.

[page] 75

Four coarse uncouth-looking species comprising this genus are in the collection. In addition to the diagnoses that may be gathered from the table (ante, p. 58), the absence of armature at the sides of the prothorax will serve at once to distinguish it from Escharodes and Axiothea, its nearest allies. The species of Sotades have all a black shining derm, closely covered with short flat hairs or scales of various shades of grey, with the usual irregular oblique patch or band just behind the middle, which characterizes so many of this sub-family. It may be observed, however, that these scales appear very liable to be rubbed off. From amongst this pubescence numerous small black shining granules crop up.

SYMPHYLETES.

Symphyletes, Newman, The Entom. i. 362.

Caput antice subquadratum, tuberibus antenniferis approximatis vel distantibus. Oculi profunde emarginati. Antennæ corpori æquales, vel multo breviores, vel multo longiores, ciliatæ vel fere glabræ; scapo pyriformi vel obconico, articulo tertio scapo duplo vel triplo longiore, quarto cæterisque brevioribus plus minusve decrescentibus, articulo ultimo apice sæpe curvato. Prothorax subtransversus, raro quadratus, aliquando rugosus, dente minuto antice instructo, rarissime obsoleto. Elytra oblonga, generaliter subparallela, æquata vel basi cristata, apice integra vel emarginata vel truncata. Pedes modice robusti, coxæ anticæ maribus aliquando spinosæ. Pro- et mesosterna elevata.

It will be seen from the above how difficult it is to formulate, with any degree of precision, the characters of a large longicorn genus. I have thirty-six species now before me, all Australian, except the three described below, each of which is very distinct or even isolated, as is the case with some others which have been referred to the genus. It is, however, to be observed that Symphyletes is a very heterogeneous genus, but it would only retain S. nodosus, Newm., the type, if it were to be divided, and then seven or eight more genera would have to be formed. At the same time Penthea and Rhytiphora are scarcely to be distinguished from Symphyletes as it stands at present. The question is, does this group form only a single genus of highly individualised species, or is it a collection of many genera? I believe if the same principles are applied as to other genera, especially of European Coleoptera, that the question must be answered in the second alternative.

Symphyletes Wallacei.

ECZEMOTES.

Caput antice subtransversum, tuberibus antenniferis validis. Oculi mediocres, profunde emarginati. Antennæ corpore breviores, setaceæ, maculis pubescentibus vestitæ, haud ciliatæ; scapo subelongato, modice attenuato, articulo tertio scapo multo longiore, cæteris gradatim decrescentibus. Prothorax transversus, æquatus, postice latior, granulatus, lateribus antice bidentatus, capite multo latior. Elytra ampla, æquata, granulata, lateribus fere parallela, postice rotundata, apice truncata. Prosternum elevatum, rotundatum, canaliculatum. Mesosternum elevato-dentatum, postice truncatum. Pedes validi; tibiæ anticæ subcurvatæ, modice elongatæ.

The type of this genus is Penthea conferta, Pasc.; but although from the true Pentheæ it is different in habit and coloration, I can find no primary character by which to separate it technically, except the toothed prosternum as contrasted with the rounded prosternum of Penthea. As secondary characters we have the prothorax broader at the base than at the apex, and the elytra entirely destitute of the elevated lines that distinguish every species of Penthea, P. granulosa, Guérin, alone excepted, but which is probably not a true Penthea. The three species described below are tolerably homogeneous, except that

[page] 80

E. agnata departs slightly from the others in the narrower and more irregular prothorax. The head in all is considerably narrower than the prothorax, which, again, is also, notwithstanding its breadth at the base, much narrower than the elytra.

Pedes æquales, breves; femora vix clavata; tibiæ posticæ et intermediæ tarsis breviores.

The following, the only species of Ælara in Mr. Wallace's Collection, was published by me some time ago under the name of Niphona arrogans; but there are several others from the Continent, such as N. Ferdinandi, N. cylindracea, N. pannosa, N. excisa, &c. The first of these has been recently separated from Niphona by M. James Thomson under the name here adopted, and the others just mentioned are undoubtedly congeneric. In both genera the tibiæ of the posterior and intermediate legs are shorter than their respective tarsi. M. Mulsant attributes to Niphona 12-jointed antennæ, the last almost rudimentary; but I have not been able to realize this character.

Mesosternum antice productum.

When the single species composing this genus was published, I referred it to Symphyletes; it has, however, a habit different from any of the species of that genus, and the presence of a strong tooth on the anterior tibiæ of the male is a sufficient justification for separating it. The spine on the anterior coxæ is unusually long, and of course is not present in the female.

Mr. Newman founded this genus on a Manilla longicorn, the Abryna cœnosa; to this he successively added four other species, which he referred to the same genus. Three of these I have since proposed to separate under the generic name of Aprophata (Journ. of Entom. i. 342), which, from their small humeral angles, seem to approach the Dorcadioninæ. The Baron de Paiva has also published a fine Cambodian species under the name of Abryna Regis Petri,* and with those described below the

* Descripção de dois Insectos Coleopteros de Camboja, 1860. I protest against double specific names, such as Niphona Regis Ferdinandi and Abryna Regis Petri. It seems to me that any such invasion of the binomial system of nomenclature should be resisted, and the names be either ignored altogether, or modified by limitation to the least objectionable of the two words intended to form the specific name.

Dark brown, almost inclining to olive, and somewhat glossy, with a very sparse greyish pubescence, except where the spots and patches occur; head large and very broad, especially below the eyes; epistome and lip elongate, pale yellowish; mandibles and palpi pitchy; prothorax rather narrower than the head (not broader, as in A. Petri), subtransverse, with the pubescence much scattered, the upper tooth forming more of an angle from the side (less of a tubercle than in A. Petri); scutellum rounded behind; elytra rather irregularly punctured, the pubescence condensed on parts to form spots and patches, the former are scattered in the intervals of the patches; these, as in the other species, form two irregular bands, interrupted, however, at the suture, and a few confluent somewhat indefinite blotches towards the apex, there is also a still more indefinite condensation at the base, the apex truncate; body beneath with a thin ochraceous-greyish pile, especially on the abdomen; legs spotted with greyish; antennæ, except at the base, almost glabrous.

Pedes validi, modice elongati; tibiæ anticæ subcurvatæ, tarsi dilatati, in maribus fimbriati. Prosternum elevatum, antice perpendiculare.

The species of this genus are more robust than Niphona and differ in several important particulars, especially in the prosternum having its anterior portion perpendicular. Niphona thoracica, Wh., and Niphona suffusa, Pasc., must be referred to it, although the former differs in its somewhat cylindrical scape; it is also peculiar for a singular wedge-shaped cleft in the prothorax. Mœchotypa suffusa (with which M. arida, Thoms. l. c., is probably identical) has three beautiful rose-coloured lines on each elytron, the under parts are also tinged with the same colour, and the two basal joints of the anterior tarsi have a pinkish hue.

EXARRHENUS.

Caput antice subquadratum, tuberibus antenniferis validis, basi approximatis. Oculi divisi. Antennæ corpore longiores; scapo elongato-ovato, articulis tertio et quarto multo longioribus, cæteris brevioribus et subæqualibus, ultimo apice curvato. Prothorax subtransversus, granuliferus, disco bituberosus, dentibus duobus lateralibus fere obsoletis. Elytra oblonga, subparallela, granulifera, lineis subelevatis instructa. Pedes modice elongati, antici robustiores, postici tenuiores, tibiæ anticæ curvatæ, intus dentatæ; coxæ anticæ maribus spinosæ. Mesosternum antice rotundatum.

The fore tibiæ of the males toothed on the inner edge, a peculiarity also found in Xiphotheata, and the granuliferous prothorax, will distinguish this genus, which has also a peculiar aspect owing in part to the elevated lines on the elytra, and the more slender legs and antennæ. From Escharodes (ante, p. 70) it differs at once in its rounded mesosternum.

MENYLLUS.

Antennæ corpore paulo longiores, ciliatæ; scapo pyriformi, articulo quarto tertio longiore, cæteris brevioribus, ultimo apice curvato. Prothorax subquadratus, irregularis. Elytra basi cristata, postice angustiora, apice emarginata. Pedes modice elongati, antici robustiores, postici tenuiores. Coxæ anticæ maribus spinosæ. Mesosternum antice dentatum.

The form of the scape, in conjunction with the irregular prothorax and spined anterior coxæ of the male, will technically distinguish this genus. The table (ante, p. 58) will show how it differs from Escharodes, Ælara and Exarrhenus, to any one of which it might be referred except for certain characters, to which it is necessary to adhere if we would differentiate these genera satisfactorily. In habit Menyllus most closely resembles the Australian genus Platyomopsis, which, however, inter alia, has the antennæ of Symphyletes.

gradually rounded to the apex, which is sinuately emarginate, at the middle on each elytron but nearly approaching the suture a curved glabrous line, at the side behind and again near the apex two others but less defined (these are probably due to abrasion, those parts of the elytra being elevated and therefore more exposed); body beneath with a thin whitish pile, the abdominal segments margined with ochraceous; antennæ and legs pitchy-brown, with very distinct white spots composed of short closely-set hairs.

In this very distinct genus the lower lip is large and cordiform, and fringed with long yellowish hairs. The scape is unusually thick, the fore tibiæ are enlarged at the extremity, and the tarsi, especially the anterior, are very short. The genus does not appear to have any near ally.

Two well-marked species compose this genus, which is quite distinct from any other in the collection. There is a curious little spine at the apex of the scape in D. semicana, but this appears to be absent in the other species.

From Dryusa (post, p. 91) this genus differs in its quadrate prothorax, shorter and more trigonate elytra, stouter legs and antennæ, and is altogether a more robust form.

DRYUSA.

Caput antice subquadratum. Oculi profunde emarginati. Antennæ maribus corpore fere duplo longiores, crinitæ scapo subelongato, sensim incrassato, articulo tertio scapo breviore, quarto tertio fere duplo longiore, cæteris æqualibus (ultimo excepto) magis brevioribus, ultimo elongato.

Pedes mediocres; tarsi æquales. Corpus crinitum.

I have already pointed out the distinction between this genus and the last. I may add, that the shorter elytra of Mispila, and therefore of its abdomen, give a backward position to the hind legs that completely alters its habit as contrasted with Dryusa. The species described below are perfectly homogeneous in their appearance. They are all covered with a greyish pile, and sufficiently sparse to allow the derm to mingle its proper hue with it. Besides the pile the whole upper surface and legs are furnished with numerous slender erect hairs, each arising from the base of a puncture, dark brown on the former except at the sides, very pale grey on the latter and sides of the elytra. On the antennæ, except the three basal joints, these hairs are confined to the lower side, there forming the usual fringe. The punctures on the elytra are in reality principally arranged in rows, except near the scutellum; they have somewhat an oblique direction, and are not very obvious; the punctures are of moderate size and strongly marked. The irregular flexuous spots or broken lines that occur on the elytra appear to be occasioned chiefly by the closer condensation of the pile. On the prothorax, the posterior transverse sulcation is well marked, the anterior is much less, and is at a considerable distance from the apex.

This is the most striking of all the genera of Niphoninæ, and it is the more remarkable inasmuch as the female has an unusually stout and lengthened tooth on the side of the prothorax anteriorly, while in the male there is no appearance whatever of any such armature. On the other hand, the male has a very powerful spine on the anterior coxa, as well as a sharp tooth on the protibia; these are denied to the females. I have dedicated the only species at present known to W. Wilson Saunders, Esq., F.R.S., &c.

MESOSINÆ.

With few exceptions this sub-family will be found to be identical with the 17th "groupe Mesositæ" of M. J. Thomson's "Systema Cerambycidarum." It is principally characterised by its long and more or less cylindrical scape, generally arising from a very short or nearly obsolete tuber, which is rarely approximate to its fellow.

Many of the members of this sub-family are among the handsomest of the Lamiidæ of the old world. They are in fact con-

[page] 95

fined to Asia and Africa, with the exception of three European species of Mesosa* (one of which occurs in England). None have hitherto been detected in Australia.† Of the twenty-one genera included in the Wallacean Collection, ten also occur on the mainland of Asia, and besides these a few more have been very recently described by M. Thomson, principally derived from the extensive collections made by the Comte de Castelnau in Malacca. Three species are known to me from North China, but from the English possessions in India I have never seen a specimen; that country is, however, nearly a terra incognita to the entomologist.

The head in the Mesosinæ is always more or less quadrate, the front generally ample, never spreading out below the eyes, the antennary tubers small, and, with one or two exceptions, widely apart; the eyes small or only of moderate size, and deeply and widely emarginate; the antennæ are more or less slender, but the scape is always long and cylindrical or occasionally slightly clavi-form, produced and having a scar-like section at the apex; many of the genera have their antennæ more or less pilose, or tufted. The prothorax is even, rarely irregular, a few genera only having a short tooth at the side.‡ In the majority of the species the elytra are also perfectly even, but in some there is a tendency to the production of elevated lines, and in one genus of basal crests (Æsopida). The legs are, on the whole, of moderate length, the anterior being almost invariably the longest, especially in the males; the femora are stout, thickest in the middle, not clavate, the tibiæ are always considerably longer than their tarsi; the tarsi are short, of equal size, except that the anterior are sometimes dilated, the three basal joints together not often exceeding the claw-joint in length. The anterior coxæ are large and globose, never armed, and their acetabula are narrowly angulated externally; the prosternum is generally raised to a level with the coxæ; the mesosternum is also elevated with few exceptions, and often produced or toothed anteriorly.

The number of species in the collection is upwards of sixty, § distributed into the twenty-one genera tabulated below.

* Dr. Leconte, however, describes a Mesosa from California. This forms the genus Synaphe, of M. James Thomson.

† The genus Meton, placed in this sub-family by M. Thomson, is, from its short scape, approximate antennary tubers, and longer and unequal tarsi, rather, I think, to be referred to the Monochaminæ.

‡ In Agelasta, a very natural genus, some of the species have a very decided lateral tooth, in the majority there is no trace of it whatever.

§ In the genus Cacia we have three or four forms, of which it is extremely difficult to say whether they should be treated as species or as varieties.

Three fine and closely allied species at present compose this genus. It is remarkable for its apparently almost glabrous surface, except that the posterior portion of the elytra is clothed with a delicate pubescence gradually increasing in density towards the apex. The genus is nearly allied to Agelasta, but the body is depressed, the antennæ are more attenuated, and the prothorax has a different outline.

Characteres fere ut in Æmocia, sed capite antice quadrato; oculis lobo inferiori rotundato; prothorace subtransverso, disco turgido; tarsis anticis haud pilosis; et mesosterno declive, medio subcarinato, vel subdentato.

In the table (ante, p. 96) the mesosternum is stated to be depressed, but this is not exactly correct; it is, however, quite different from the elevated, broad and flattened mesosternum of Æmocia. In fact it is rather declivous than depressed (more or less so according to the species), is much narrower, and has a little oblong tooth, or rather carina, in the middle. The type (A.

[page] 99

calceatus) is found in Java. Of the four species here enumerated three are closely allied; a larger series of specimens might possibly show that one of them—A. simulans—is only a local sub-species.

PLANODES.

Planodes, Newman, The Entom. i. 323.

Caput antice quadratum, tuberibus antenniferis approximatis, apice extus emarginatis. Oculi prominuli, modice emarginati. Antennæ corpore longiores, apicem versus lineares; scapo elongato, subcylindrico, apice cicatricoso, extus producto; articulo tertio longissimo, apice dentato; cæteris plus minusve brevioribus vel subæqualibus; ultimo brevissimo. Prothorax subangustus, basin versus latior, muticus. Elytra oblonga, supra planata, lateribus subito angulato-declivia, humeris productis, apice rotundata. Pedes mediocres; femora vix clavata; tibiæ intermediæ emarginatæ; tarsi breves, antici aliquando dilatati. Prosternum elevatum. Mesosternum antice productum.

Mr. Newman, in characterising this genus, describes the antennæ as being distant at the base, the head between them sulcated. The latter character is due to the strongly developed antennary tubers, closely approximate at their origin, but rising

[page] 101

obliquely, and forming a very deep and angular depression as they diverge. It is, however, incorrect to say that the antennæ are distant at the base, except in the sense that they are not contiguous; they are in fact much more approximate than in almost any other genus of the sub-family. In both sexes there is a strong tooth, scarcely long enough for a spine, at the apex of the third joint, and the antennæ, instead of becoming gradually more attenuated towards the tip, have the last four or five joints nearly linear, or in the males of some species (P. papulosus, P. vicarius, &c.) even slightly thickened, especially the terminal joint. The elytra are almost perfectly flat above, but bent suddenly down so as to form an angle about midway between the suture and the external margin; this angle is sometimes so prominent as almost to form a carina, and generally it has a row of shining granules topping it, especially at the base; towards the apex there is almost always a second carina, short and oblique, and outside this, near the margin, there is an indication of a third. The type (P. quaternarius) is from Manilla; to this Planodes satelles of the collection approaches the most nearly of the eight homogeneous species discovered by Mr. Wallace in various localities between Malacca and New Guinea.

Stegenus denticornis, Chevrolat (Rev. et Mag. de Zool. 1858, p. 83), from Java, is a Planodes.

EREIS.

Eris, Pascoe, Trans. Ent. Soc. ser. 2, iv. 110 (nec Koch).

Caput antice quadratum, tuberibus antenniferis brevibus, apice integris. Oculi frontales, modice emarginati. Antennæ corpore multo longiores; scapo elongato, subcylindrico, apice cicatricoso, extus producto; articulo tertio longiore, apice haud dentato; cæteris gradatim brevioribus et tenuioribus. Prothorax fere quadratus, muticus, capite haud latior. Elytra oblonga, depressa, subcarinata. Pedes mediocres; femora haud clavata; tibiæ intermediæ integræ; tarsi subangustati. Prosternum elevatum, postice perpendiculare. Mesosternum antice dentatum.

When I proposed this genus some years ago I was unacquainted with its two nearest allies, Planodes and Anancylus, and was therefore very doubtful as to its affinities. The former of these it most nearly resembles in habit, but differs in its short or almost obsolete antennary tubers remote at the base, and in its normal antennæ; from the latter it differs in habit, shorter antennæ and the presence of raised lines on the elytra. The lower lobe of the eye is much more frontal than is usual in this sub-family. A second species has been described in the Journal of Entomology (vol. i. p. 347) from Cambodia, and I have now a third species,* also from Cambodia, which departs from the type in having its prothorax more rounded at the sides, and its elytra shorter and more convex; its abdominal segments also, at least the three intermediate ones, are furnished with semicircular patches of coarse hairs, as in Symphyletes and some other genera.

The word Eris had been previously used by Koch for a genus of Arachnida; I have therefore altered it to Ereis.

* This may be characterized as follows:—
Ereis ventralis.
E. fusca, sparse irregulariter griseo-pubescens; prothorace subtransverso, lateraliter rotundato, minute granulato; elytris brevibus, convexis, carinis fere obsoletis, nigro-maculatis, præcipue post medium lineâ transversâ macularum; corpore infra fusco, subnitido, abdomine glabro, segmentis tribus intermediis lateribus dense pilosis; tibiis tarsisque annulatis; antennis nigro-maculatis.

CACIA.

Cacia, Newman, The Entom. i. 290 (1842).
Corethrophora, Blanch. Voy. au Pôle Sud, iv. 301 (1853).

Caput antice quadratum, tuberibus antenniferis basi sub-approximatis vel remotis. Oculi profunde emarginati. Antennæ in maribus corpore aliquando duplo longiores, in feminis multo breviores; scapo elongato, cylindrico, apice producto; articulo tertio multo longiore, rarissime plumigero; quarto breviore, sæpe subtus piloso; cæteris brevioribus, in feminis brevissimis. Prothorax quadratus vel subtransversus, lateraliter rotundatus. Elytra convexa vel leviter complanata, apice rotundata. Pedes modice elongati, antici in maribus longiores, protibiæ subcurvatæ vel in feminis rectæ; tarsi in utroque sexu æquales. Mesosternum subangustum, antice dentatum.

M. Blanchard (ubi sup.) proposed the genus Corethrophora for a species (C. semiluctuosa), which I am unable to distinguish satisfactorily from Cacia. Almost the sole character to authorize its separation is the stronger and more approximate antennary tubers; but this character is modified in individuals belonging to what I believe to be the same species—a species subject to such

[page] 107

an amount of variation that its characters, if it were the type of a genus, ought to be particularly strong. Confining Cacia to those species which have a narrow mesosternum* toothed anteriorly, and the third and fourth joints of the antennæ not thicker than is usual, but the former much longer than any other joint, there are still considerable modifications in the genus which it is possible may lead to further division. Cacia setulosa, Pasc., from Java, but not in this collection, furnished with numerous erect hairs over the upper surface, is one of the most aberrant. Another species, Cacia compta (post, p. 112), has a tuft to the third as well as the fourth joint of the antennæ, but this is so far untrustworthy that the tuft is sometimes absent from individuals of those species which appear to have it normally. The type of the genus, Cacia spinigera, Newm., has a little spine, or rather tooth, on the apex of the third antennal joint, but this Mr. Newman very properly considers as of specific value only, his second species, C. aspersa, being without it. Mr. White has described a species from China, which he has named Cacia latifasciata, but which strictly cannot be considered to belong to this genus. The species appear to be subject to very considerable variation; in nearly all the fifth joint of the antennæ is wholly or partially white.

* A Cacia-form, not belonging to the Wallacean Collection, which is excluded by having a broad flattish mesosternum, may be shortly characterized here. The specimen is a female.

Length 6—8 lines.

From a large number of specimens now before me I have not the slightest doubt that all the names given above are referrible to one and the same species. Under ordinary circumstances I should have taken the earliest name, but putting aside the objection that this is simply a barbarism, and that at the very moment of giving it the author believed that though ticketed (indiquée) from Vanikoro the insect nevertheless came from New Guinea or the Celebes, and its adoption, therefore, would be only to perpetuate an error, the obvious convenience of a collective designation for a species subject to such an extraordinary amount of variation becomes almost a necessity.

The names of these four forms may be maintained as so many centres from which to survey the species. Starting from the comonest forms, which seem to group themselves round C. histrionica, we find that they are black, with a white band across the elytra posteriorly, the apex, scutellum, and elytra around it, also white. A stripe from the scutellum passing along the suture joins the band, and then we have the Corethrophora semiluctuosa. Through several varieties the white increases, the black between the band and stripes gradually diminishing and disappearing, in which state it is the C. anthriboides. Sometimes there is a black spot on the white near the shoulder, and the sutural stripe is prolonged to the apex; this gives two black patches to each elytron. In one beautiful specimen the

[page] 109

apical black is crossed by three pure white lines, and there is a dash of black from each shoulder. Returning to C. histrionica we have in one direction the white entirely disappearing, except the central thoracic stripe prolonged a little on the scutellum and elytra, and in another the band and sutural stripe taking a finely linear form. This is about the most simple of all the varieties, but starting from this we first see a little white dash near the shoulder, and then this is directed obliquely inwards with a gentle curve until it approaches the middle of the elytron, when it takes another turn downwards and backwards, and joins the posterior line. When in addition to this there is an ocellate spot near the apex we have "Vanikorensis." Generally there are only indefinite indications of this spot.

Yellowish-red to dark brown, with intricate well-marked lines of greyish or yellowish-grey; on the prothorax there are two longitudinal lines on each side, together somewhat resembling the figure 8; on the elytra these lines are chiefly transverse and so disposed as to leave three dark irregular band-like patches; the posterior one is especially band-like, and sometimes becomes a complete band; at other times these patches are divided, or the fine greyish lines shade off into a nearly uniform colour, leaving, however, the pattern untouched; antennæ unicolorous without tufts, or tufted with the fifth and base of the fourth joint white; tibiæ with the middle or whole of the basal half pale grey or white.

This is also a suspicious species, having precisely the same style of coloration on the prothorax as the last two, with the addition of a patch on each side, but this is also the case with some individuals of C. intricata. In C. plagiata the prothorax is very much broader than in C. scenica, (but even this character is variable in C. instabilis). As to the elytra, we have only to connect the three bands of C. intricata by a stripe along the suture and carry the stripe down to the apex, and we have pretty nearly C. plagiata. The two specimens before me show some differences, and probably belong to a variable species, but the evidence is not sufficient at present to justify its union with the last.

The cylindrical prothorax, the thickened 2nd, 3rd, and 4th joints of the antennæ, the third being very little longer than the scape, and the different habit, are characters which will at once distinguish this genus from Cacia. Mr. Wallace remarked that it carried its antennæ "straight and close together, appearing like a Brenthus."

I have separated this genus from Cacia, to which I formerly referred it, on account of its short antennæ in both sexes, its elytra being callous at the base, and its mesosternum being simply produced anteriorly, not having a distinct tooth. The legs also are shorter and the body more depressed than in any species of Cacia. My original specimen was much worn. These insects were taken flying in the jungle.

Hab.—Singapore, Sarawak.

Brown, with a very thin and fine greyish or yellowish-grey pubescence; a white line commencing on the prothorax behind the eye, but also sometimes showing on the head above it, passes obliquely backwards to the shoulder; within this but confined to the prothorax is a dark-brown stripe; on the elytra behind the middle a curved dark-brown band, scarcely attaining the suture, bordered anteriorly by a thin line of white; space around the basal callus, a spot on the suture towards the middle, and two or three near the apex, dark brown or black; body beneath dark brown, thinly pubescent; legs reddish-brown, the distal half of the tibiæ and the tarsi black; antennæ reddish-brown, the fourth joint black, the fifth white, the remainder darker towards the apex.

MNEMEA.

Caput magnum, antice subquadratum, tuberibus antenniferis brevibus, remotis. Mandibulæ elongatæ. Oculi fere divisi. Antennæ corpori æquales; scapo subbrevi, subcylindrico, apice producto et cicatricoso; articulo tertio longissimo; quarto brevi; cæteris iterum brevibus et gradatim decrescentibus. Prothorax transversus, capite vix latior, lateribus rotundatus. Elytra brevia, lateraliter gradatim angustiora, humeris haud productis, apice rotundata. Pedes breves, antici validiores, femora incrassata, tibiæ anticæ trigonatæ, intermediæ integræ, posticæ breviores; tarsi omnes breves,

antici latiores. Pro- et meso-sterna elevata, hoc antice dentato. Abdomen segmento ultimo elongato. Corpus subdepressum.

This genus was accidentally omitted from the table (ante, p. 96), but it will stand after Ipocregyes, from which it differs in its large head, elongate mandibles, short scape strongly produced at the apex, stouter legs, particularly of the fore pair (which are both larger and thicker in both sexes), and other characters. The curious little insect, at present the only member of the genus, is remarkable for its large head and short scape, this latter character being quite at variance with those of its sub-family; it is, however, so nearly allied to other species of the group, that it could not, without violence, be separated from them.

COPTOPS.

Lachnia, deuxième division Coptops, Serville, Ann. Soc. Ent. de France, iv. 64.

Caput antice subtransversum, vertice elevato, tuberibus antenniferis brevibus, remotis. Oculi mediocres, fere divisi. Antennæ in maribus corpore longiores; scapo cylindrico et articulo tertio longiore; sequentibus brevioribus, ultimo apice unguiculato. Prothorax transversus, capite latior, lateribus antice dentatus, disco sub-irregularis, basin versus latior. Elytra oblonga vel subtrigonata, fere regularia, apice integra. Pedes robusti, generaliter æquales, protibiæ rectæ, tarsi breves, triangulares. Prosternum elevatum, rotundatum. Mesosternum antice dentatum, vel productum.

Technically this is rather a weakly characterized genus, and Serville, whilst recognizing its distinctness as a group of some sort, seems to have had no better plan than attaching it as a "division" to Lachnia, which, from his description, appears to belong to the Hypselominæ. The genus is well represented in Africa, and on the mainland of Asia. Mr. Wallace's Collection contains nine very distinct species, all, with some exceptions, tolerably homogeneous, but owing to the mixed and indefinite style of their coloration very difficult to describe; and this difficulty is increased from the circumstance that individuals vary among themselves. Generally the derm is dark brown and glossy to a certain extent,

[page] 117

sometimes entirely covered with the pubescence, at other times the pubescence is so thin that the derm may be readily seen, and imparts its colour to modify the general effect, or portions of it may be absent or nearly so, and then there are spots or patches of irregular shape, not always exactly the same even in the same species.

There is also frequently a little dark ring formed round the edges of the punctures; these in the following descriptions I have spoken of as "puncta" or "points" to distinguish them from ordinary spots or "maculæ." The puncturation, otherwise, is everywhere very fine, and is not to be seen without a lens. The mesial line on the head is very slight, scarcely forming a sulcation. The prothorax, shorter or more transverse in the female, is, sometimes, much broader at the base than anteriorly, but this is a character which can scarcely be realized by description, unless when very decided. The disc is generally marked by a more or less V-shaped impression anteriorly, posteriorly a similar mark is reversed, the apices of the two being connected by another short longitudinal impression; the anterior mark, and sometimes the posterior, runs into a transverse groove; generally, too, the disc has two small tubercles, one on each side of the longitudinal impression. The slight variations which occur in these characters are very difficult to define so as to be thoroughly intelligible.

In nearly all the species the antennæ are annulated with white or pale grey; this colour is found at the bases of most, sometimes of all, the joints, beginning with the third. Except in C. undulata, the elytra are rounded at the apex. In C. lacertosa the fore legs of the male are longer and stouter than the intermediate and posterior; in a less degree, this is also the case with C. polyspila, C. pardalis, and a few others not in this Collection. This character gives them a somewhat different habit from the more normal species. The males have longer antennæ than the females, and it may be generally noticed that their elytra are much more trigonate in outline.

* Another species, allied to this, from Cambodia (C. vomicosa) must also be separated from Abryna, as it is now limited, although perhaps, from their more trigonate and convex elytra, pardalis and vomicosa may be thought to accord somewhat less decidedly with Coptops.

The form of the prothorax, in conjunction with the normal proportion of the length of the scape to that of the third joint of the antennæ, and the non-unguiculate apex of the last joint, will readily distinguish this genus from Coptops; while the rounded prosternum, inter alia, separates it from Clyzomedus. The three species are on the whole tolerably homogeneous in point of form; in size, judging from the few specimens before me, there is a little discrepancy.

The type of this genus is a Manillan insect (A. transversa), described with two other species by Mr. Newman in 1842. Mr. Wallace's researches have added nine more to the list, of which five have been described by Mr. White, and another by myself.

[page] 124

Besides these the late M. Mouhot obtained three species in Cambodia, which were published by me as Agelastæ, but only one of which can be retained in the genus as here defined.* I have also species in my collection from Pulo Penang and from Patani in Malacca, † and another from Java, unpublished, is the Chœromorpha pigra of Dejean's Catalogue. The species with scarcely an exception are remarkably distinct, and, omitting one, which is only placed here provisionally, the genus, as now limited, is a very natural one. Nevertheless there are certain peculiarities which it may be well to notice. In A. irrorata, there is a very decided process on the side of the prothorax, not exactly a tubercle or a tooth (as in A. Polynesus), and there is a little angularity also in A. sobrina and A. sulphurea. The male A. Wallacei has the antennæ scarcely longer than the body, while in A. sobrina they are half as long again. In the male of a species from Penang (not yet published), and apparently so closely allied to A. Wallacei

that I at first thought it might be a variety of it, the antennæ are twelve-jointed; the supplementary joint is not simply an appendage of the eleventh, but in all respects a true and perfect joint. A. callizona has the distal end of the protibiæ densely tufted. In the female of A. Polynesus the antennæ are thickened towards the apex. Excluding A. basalis, which cannot be considered a true Agelasta, the genus might be divided into two sections, 1st, those with the third joint of the antennæ longer than the scape, and 2nd, those in which it is shorter; but between these there is the Manillan A. transversa, in which they are about equal. This, therefore, seems to be one of those genera in which the comparative lengths of these joints (which generally afford most reliable characters, and this may also be said of the antennæ to a certain extent), are to be considered as only of secondary importance.

All the members of this genus met with by Mr. Wallace were found on fallen trees, but "fell off and lay as if dead when disturbed." A. Newmanni was found "flying above newly fallen timber."

distinct and may be known at once by the third antennal joint being very much shorter than the fourth, by its much smaller or rather narrower head, especially below the eyes, and by the longitudinal lines which descend in front, in form resembling the letter W; the eyes are also larger, and there is only about their own length between them and the basal line above the mandibles, while it is nearly twice the distance in A. sobrina. Little can be said for colour in so variable a species as the former, but in this the elytra are everywhere spotted or rather speckled with white, while in A. sobrina the speckles only occur on the brown portion or at the extreme edge of the rufous; legs and antennæ less distinctly coloured; protibiæ in the male (in my specimen) not much larger than in the female.

Black or rather dark brown, shining, with a short, interrupted, ashy pile; head glabrous, except the narrow pubescent stripes on the vertex, and another over the eye descending to the lip; prothorax partially pubescent at the sides, which are prominently

[page] 129

rounded, nearly glabrous in the middle; scutellum transverse, rounded behind; elytra with the pubescence closely condensed at the base, and a little behind the middle, thence forming two broad well-marked bands,* rest of the elytra spotted or patchy from the absence of pubescence; body beneath glossy brown or black, the abdominal segments bordered with white; antennæ and legs brown, the tibiæ gradually becoming greyish from the increase of pubescence, the tarsi entirely pubescent.

The following is provisionally placed in this genus.

Agelasta basalis.

A. pube subtilissima rufo-fusca griseo-irrorata tecta; elytrorum singulorum basi macula ochracea.

Hab.—Menado.

Covered with a very delicate reddish-brown pubescence, spotted with greyish, and having at the base of each elytron an ochraceous patch; head obscurely mottled with greyish and brown; prothorax not much narrower anteriorly than behind; scutellum dark brown; elytra with two large patches on each side free from the greyish spots, otherwise these spots are very irregular, some of them being confluent, but the greater part are isolated and very distinct; body beneath with a greyish pile on the breast, reddish-yellow on the abdomen; legs rather obscurely ringed with dark brown and grey; the tarsi, except the extremity of the claw-joint, pale ashy; antennæ dark brown, the bases of the joints, from the third inclusive, pale ashy.

Length 6 lines.

This species differs considerably from the rest of the genus; but in the absence of any decided character, and as I have only a single example, I am unwilling to propose a new genus for its reception. It is much less robust in its habit, narrower, the sides more parallel, and although a male, the fore-legs are not very perceptibly thicker or longer than the others; they are, however, slightly curved, which, with other discrepancies, prevents it being placed in Sorbia.

SYRRHOPEUS.

Caput antice quadratum, tuberibus antenniferis distantibus. Oculi profunde emarginati. Antennæ corpore longiores;

A beautiful insect, having a singular resemblance to Agelasta callizona in its coloration, is the sole representative of this genus. From Agelasta, however, it is abundantly distinct, not only in the form of the prothorax and mesosternum, but also in the straightness of the protibiæ,* and the elongated, parallel, and dilated anterior tarsi, while on the prothorax little glossy black granulations take the place of punctures.

Syrrhopeus agelastoides. (Pl. VII. fig. 3.)

S. tenuiter pubescens, dense fusco-irroratus; prothorace granuloso; elytris fascia lata mediana apiceque rubescentibus.

Hab.—Sarawak.

Covered with a short dense pubescence of a reddish colour, very closely spotted with brown on the upper surface, except the bands on the elytra, but less so on the anterior femora and base of the antennæ; head nearly as broad as the prothorax, the latter scarcely longer than broad, the sides regularly rounded, the disc with black glossy granules; scutellum somewhat quadrate; elytra punctured, chiefly at the base, with a few scattered granules, the median band rather broad and of a clear pale brick-red colour, the apex also of the same colour; body beneath dark brown, with a very sparse greyish pubescence; legs mostly reddish, the anterior femora spotted with brown, the distal extremities of the tibiæ, the basal joints of the intermediate and posterior, and the two basal joints of the anterior, tarsi, the tips of the claw-joints and the claws, black; antennæ reddish, the tips of the third and most of the following joints black.

The only species of this genus has very much the habit of Agelasta basalis (ante, p. 129), but is distinguished by several characters, notably by the form of the mesosternum.

Sorbia tarsalis. (Pl. VI. fig. 5.)

S. tenuiter pubescens, ochracea, dense fusco-irrorata; elytris fascia irregulari ochracea post medium; tarsis albidis.

Hab.—Sarawak.

Pubescence very short, ochraceous, closely sprinkled with dark brown; head rather roughly pubescent, with a few back granules on the vertex, lip hairy, very narrow and elongate; prothorax nearly parallel at the sides behind the anterior impressed line, the disc with numerous granules; scutellum subtransverse; elytra rather distinctly punctured at the base, with a few granules, behind the middle a narrow but rather interrupted and zig-zag ochraceous band, in another specimen the band is represented by a few oblong patches placed nearly side by side; body beneath dark brown, shining, with a thin greyish pile; legs pale greyish, mottled with brown; tarsi with the two intermediate joints, and the adjoining portion of the claw-joint, whitish; apex of the claw-joint, claws, and basal joint, dark brown; antennæ varied, the scape and basal half of the third joint pale greyish, spotted with brown, the rest of the antennæ dark brown, with the bases of the fourth and fifth, and the eighth, ninth and tenth joints, pale greyish.

Caput antice subquadratum, tuberibus antenniferis validis, fronte sulcata. Oculi laterales, valde emarginati. Antennæ corpore longiores; scapo cylindrico; articulis tertio et quarto longioribus et æqualibus; sequentibus multo brevioribus. Prothorax suboblongus, capite latior, antice transversim impressus, lateraliter vix rotundatus. Elytra oblonga, basi subcristata. Pedes mediocres; protibiæ subcurvatæ; tarsi haud dilatati; coxæ anticæ productæ. Prosternum demissum. Mesosternum antice leviter rotundatum.

K 2

[page] 132

The anterior coxæ in this genus are remarkably produced, while the prosternum scarcely rises above their roots, and the mesosternum is gently rounded anteriorly, and neither dilated nor toothed. The crest at the base of each elytron is very small, and is accompanied by two slightly elevated lines externally. The transverse impression on the prothorax is joined behind by a shallow longitudinal excavation, dividing the disc into two very slight lobes. In habit and dullness of coloration the genus resembles some species of Praonetha.

Ale agraria. (Pl. VI. fig. 6.)

A. modice pubescens, fusca, leviter griseo-varia.

Hab.—Batchian.

Covered with a short, moderately dense, darkish brown pubescence, slightly varied with grey; head deeply sulcated between the antennary tubers, clothed with a yellowish-grey pile; prothorax slightly punctured, abruptly narrowed anteriorly, behind which its sides are nearly parallel; scutellum nearly semicircular; elytra irregularly punctured, the punctures nearly confined to the basal half, crest at the base small and tooth-like, two raised lines externally, not extending to the apex, a light grey spot at the end of the innermost, and a few obscure greyish patches, chiefly towards the base; body beneath brownish; legs and antennæ very slightly pubescent.

Mesosternum elevatum, antice dentatum.

There appears to be only one species of this genus, which will be readily recognized by its irregular elytra, crested at the base, and by the raised lines forming a rude kind of reticulation over them.

The sole exponent of this genus is a very handsome insect, first found at Sarawak by Mr. Wallace, and subsequently in Laos by M. Mouhot. It is allied to, but is very distinct from, the two following genera. The antennæ vary in length in both sexes.

PALIMNA.

Palimna, Pascoe, Journ. of Entom. i. 346 (1862).

Cylanca, J. Thomson, Syst. Ceramb. p. 58 (1864).

Caput antice quadratum, tuberibus antenniferis validis, divergentibus, basi approximatis. Oculi late emarginati. Antennæ in maribus longissimæ; scapo obconico; articulo tertio recto, duplo longiore; cæteris paulo brevioribus, fere subæqualibus, vel leviter gradatim decrescentibus, ultimo præcedente longiore excepto; articulo septimo apice lateraliter laminato-producto; in fœminis articulis tertio et sequentibus multo brevioribus.

Pro- et meso-sterna simplicia, hoc antice rotundato.

The characters which separate this genus from Golsinda are principally the comparatively short and obconical scape, the simple mesosternum, the toothed prothorax and the irregular elytra. Olivier, who has described and represented one of the species (Tom. iv. No. 67, pl. xx. fig. 151) under the name of Cerambyx annulatus, says, however (p. 95), "thorace mutico;" but although small, there is undoubtedly a tooth on each side, besides the tooth-like tubercles on the disc, and in another species found in Laos and in Pulo Penang, it is far more strongly developed, especially (and this is very remarkable) in the female. The males in this genus, besides the much greater length of the antennæ, have a very prominent lamina at the tip of the seventh joint, this is rounded at the end and its sharp margins fringed with short hairs; there is a tendency to the same structure in the sixth as well as in the fifth joint, but in the latter it is less evident, and traces of these

[page] 135

little prominences are also obvious enough on the antennæ of the females.

GONIAGES.

Caput, oculi et antennœ ut in Palimna, sed articulo sexto laminato-producto. Prothorax quadratus, lateribus parallelus et inermis, disco subirregulari. Elytra, pedes et sterna ut in Palimna.

There is very little beyond the form of the prothorax to separate this genus from Palimna; the position of the "lamina" on the sixth instead of the seventh antennal joint is perhaps more remarkable than important.

PHEMONE.

Phemone, Pascoe, Trans. Ent. Soc. ser. 2, v. 48.

Caput parvum, antice quadratum, tuberibus antenniferis modice distantibus. Oculi mediocres, profunde emarginati. Antennæ graciles, corpore longiores; scapo subtenuato, cylindrico; articulo tertio longiore; cæteris brevioribus, ultimis obsolete articulatis. Prothorax latitudine longitudini fere æqualis, antice angustior, lateribus rotundatus. Elytra oblonga, subdepressa, humeris haud productis. Pedes subbreves, antici longiores; protibiæ subrectæ; tibiæ intermediæ integræ tarsi breves, dilatati, antici valde transversi. Mesosternum antice productum.

This is one of those isolated genera, of which so many occur among the Longicornia. The head is much smaller than is usual in this sub-family, and is in a line at the sides with the prothorax, while, from the narrow elytra and receding shoulders, there is not that disproportion at the junction between them and the prothorax which we find in the other members of this group. In these respects it approaches the Apomecyninæ, but the elongate scape and longer anterior legs, especially in the males, point rather to a location in the present sub-family.

Black, somewhat glossy, moderately punctured; a pure white line, composed of closely set hairs, commencing behind the eye, is continued over the prothorax and elytra at the sides to the middle of the latter, where it curves inwards and joins its fellow at the suture; behind this, but not quite at the apex, a crescent-shaped line, from which at the suture a finer line is continued to the apex; rest of the prothorax and elytra nearly glabrous; body beneath dark, shining, with a thin greyish pile; legs and antennæ black.

SODUS.

Caput antice transversum, tuberibus antenniferis remotis. Oculi magni, profunde divisi.

Prothorax capite vix latior, turgidus, lateraliter rotundatus. Elytra regularia, subparallela. Pedes mediocres; protibiæ curvatæ, intermediæ integræ; tarsi breves, antici dilatati, intermedii et postici æquales, subdilatati. Pro- et meso-sterna simplicia. Corpus setulosum.

An isolated genus differing from all others of its sub-family in its scape, which is rounded and not produced at the apex, although there is a slight approach to this structure in Ipocregyes. The habit, however, is not very different from Cacia. Another species found in Pulo Penang.

Dark brown, shining, the very thin greyish pubescence scarcely apparent except under the lens, but every part, except beneath, with long scattered erect hairs; head glabrous and glossy brown in front, the vertex and sides of the face covered with snowy-white hairs; prothorax turgid on the disc, the centre with a longitudinal impression; scutellum very short, transverse; elytra remotely and irregularly punctured, a very narrow flexuous white band near the base, and a W-formed mark of the same colour on each elytron towards the apex; in both cases the brown behind is of a somewhat darker tint; there are also vestiges of another band across the middle; body beneath reddish-brown, almost glabrous; legs reddish, especially the tarsi, and more thickly clothed with long hairs than elsewhere; antennæ brownish, with the three or four basal joints clothed with white hairs.

Length 4 lines.

DIEXIA.

Caput antice transversum, tuberibus antenniferis brevissimis, remotis. Oculi profunde emarginati. Antennæ 12-articulatæ, corpore paulo longiores, longe-ciliatæ, præcipue articulis ultimis; scapo modice elongato, subincrassato, apice rotun-

Elytra oblonga, subangusta. Pedes læves; tibiæ anticæ curvatæ tarsi haud dilatati. Pro- et meso-sterna depressa. Abdomen segmentis subæqualibus.

This remarkable little genus with its twelve-jointed antennæ, peculiar scape, and depressed pro- and meso-sterna, would almost appear to be out of place in this sub-family; perhaps, indeed, it might have been better ranged with the Apomecyninæ. I have only seen a single example, apparently a male, which, according to Mr. Wallace's note, was found "under fallen timber."

Diexia punctigera. (Pl. VII. fig. 1.)

Hab.—Singapore.

Dark brown, somewhat glossy, with scattered erect hairs, otherwise nearly glabrous, except the head and certain greyish pubescent lines on the prothorax and elytra; the upper surface strongly and rather remotely punctured; head covered with shaggy patches of hair in front, behind the eyes a white mark, which corresponds with a stripe along the side of the prothorax and over the shoulder to the middle of the elytra, where it joins a short transverse line, the apex of each elytron bordered with a white line on its sutural margin, which is connected behind with a transverse one; body beneath pubescent, whitish; legs covered with long whitish hairs, the tarsi black; antennæ hairy, pale greyish or white, the first, second, fifth and last two joints, and the tips of the third and fourth, black.

Length 3 lines.

APOMECYNINÆ.

Many of the genera of this sub-family, as it is here limited, have been, hitherto, widely dispersed in systematic works; but, taking their general characteristics into consideration, we get a long series of forms, many of them very remarkable, but which, when seen together, seem to be sufficiently connected to justify their juxtaposition.

The body of these insects is generally elongate, and either cylindrical, fusiform or irregular, that is, with the elytra broader than the prothorax; at the same time the legs are below the usual

[page] 139

length, and often very short, so as not to extend beyond the abdomen. The prothorax is rarely spined or toothed, and is frequently not broader than the head; the latter is more or less quadrate in front, with the antennary tubers approximate at the base, except in Euclæa, and a few other genera, and the eyes are small and emarginate. The elytra are occasionally crested, but in many cases these crests are simply expansions or elevations of a carina or raised line, and have then no generic importance. The abdomen has sometimes all the segments except the basal one of equal length. But it is in the antennæ that the most frequent modifications of structure are met with. Sometimes they are entirely plumose, at other times the plumosity is confined to one or more particular joints, either surrounding them entirely or forming a dense or a pectinated fringe beneath them. In many genera it is difficult to detect the articulations of the terminal joints, but in Cloniocerus the very reverse of this prevails, and each joint after the fourth is drawn out on one or both sides at the tips. When very short (and they are rarely longer than the body) it is owing to the last seven joints being unusually abbreviated. The scape is not produced, and never scarred at the apex.

The affinities of the Apomecyninæ are numerous. To the Niphoninæ they approach through Praonetha on the one side and Ægomomus on the other, while Diexia in the preceding sub-family might, as I have already observed, have been equally well placed in this. From such short-footed groups as the Phytœciinæ and Obereinæ, they may be distinguished by their simple claws, and from the Saperdinæ by the emargination of the intermediate tibiæ. The Hippopsinæ have their antennæ contiguous at the base; this is never the case with the Apomecyninæ. It is scarcely necessary to observe that none of the characters distinguishing secondary groups are absolute. Here and elsewhere are ambiguous genera, whose position, in the absence of any obvious affinity, depends on the importance to be attached to certain points of structure. Perhaps the most aberrant genera in the sub-family are Cloniocerus and Desmiphora, but these are bridged by such forms as Apodasya, Atelodesmis, Eupogonius, &c. But none of these belong to the Malay fauna.

Albana and Stenidea are the only European exponents of this sub-family. Mycerinus (which although represented in Africa and Australia has not been found by Mr. Wallace) and a few other genera recently added to our lists represent it in Australia. In America there are Agennopsis, Eupogonius, Phidola, Eudesmus, Eupromera, Hebestola, and many more. Africa contributes Tecton, Enaretta, Cormia, Elithiotes, Cymatura, Sophronica, and

[page] 140

others. Most of the Asiatic genera occur in the Malayan Archipelago; there are, however, others yet undescribed, which so far appear to be Asiatic only.

There are twenty-eight genera in the collection, and one hundred and sixty-four species. In the following table of the genera I have intentionally given prominence to the most obvious characters, rather than the most important.

This, although a most distinct and remarkable genus, may be considered a modification of Synelasma, wanting the prothoracic tooth, and having the first three joints of its antennæ plumosely fringed. The species described by M. Thomson, C. antennalus, is from Java. From the clause "antennarum art. 2—3 et 5—11 nigris, artic. 3° flavo, apice nigro," and from no mention being made of the fringe clothing the upper part of the third joint, I have come to the conclusion that the example described below is a distinct although nearly allied species, the more so that I have recently seen another species from Pulo Penang, to which the same remarks may be applied.

Caput antice transversum; fronte planata, tuberibus antenniferis brevibus, valde remotis. Oculi parvi, profunde divisi. Antennæ breves, lineares; scapo cylindrico, basi tenuiori; articulis tertio et quarto multo longioribus; cæteris brevissimis, apicem versus plus minusve pectinato-fimbriatis.

Elytra ampliata, convexa, brevia, apice rotundata, basi generaliter cristata. Pedes robusti, breves. Pro- et meso-sterna elevata.

Four well-marked species of this genus are in the collection. Three of these have basal crests on the elytra, varying, however, considerably in their extent and character, while the fourth is not only without the crests, but also without the anterior prothoracic tooth. In other respects it is so conformable that it scarcely seems justifiable to separate it generically. The curious little hairy comb-like brushes fringing the last five or six joints of the antennæ are, I think, not confined to one sex, at least one of the specimens before me appearing to be a female. The last seven of these joints are so short that together they scarcely exceed half the length of the four preceding.

Perhaps this genus might have been better placed in the preceding sub-family, on account of its quadrate front and elongate scape; but as the latter is entire at the apex, and the antennæ have the same curious pectinated fringe as in Synelasma, I prefer to consider it a member of the same group as the last-mentioned genus.

From Praonetha this genus differs in the toothed prothorax gradually enlarging to the base, the more convex elytra giving the back a rounded outline (not nearly straight as in that genus), the nearly linear antennæ, the produced mesosternum, and the toothed intermediate tibiæ.

The cylindrical form of the antennal joints, masking, as it were, the lines of articulation, and the lateral tooth of the prothorax, distinguish this genus from Praonetha. From Atmodes it differs in the form of the scape and the convexity of the prothorax and elytra.

The large basal joint of the anterior tarsi is probably a character of the male only. The form of the elytra, however, will readily distinguish the genus. My specimen has a broad darkish band in the middle of the elytra, apparently from abrasion.

Pro- et meso-sterna elevata. Propectus elongatum.

A fine and very distinct genus, remarkable for its broad front and elevated vertex, and particularly for its elongate propectus, as in the Monochaminæ. The prothorax has a well-marked tooth on each side (not two, as Mr. Newman's description seems to imply) in the type E. albata, but this becomes a mere tubercle in the other species, and in one, E. nigritarsis, there is scarcely a vestige of it. There are four* Manillan species in addition to the two here described.

* Two of these are, I believe, undescribed.

Nearly as large as E. albata (11 lines), but narrower; prothorax less parallel at the sides, scutellum smaller, and elytra with well-marked punctures. E. albata has a close dark-brown uninterrupted pubescence, with a large white patch covering the elytra, except at the apex and shoulders. E. capito is the "exemplarium alterum" of Newman.

Pro- et meso-sterna elevata, producta, vel dentata. Corpus subdepressum.

Atmodes is better known, perhaps, under its old name of Milothris, Dej., which M. Thomson has changed in consequence of its having been previously used for a genus of Lepidoptera. The genus is related to Mycerinus and Apomecyna, but may be distinguished (inter alia) by its irregular and toothed prothorax, and its strongly elevated and produced sterna. The type is a well known and very common insect, whose synonymy has latterly been strangely complicated.*

Apomecyna, Serville, Ann. Soc. Ent. de France, iv. 77.

Caput antice transversum, tuberibus antenniferis validis, basi vix approximatis. Oculi mediocres, grosse granulati, late emarginati. Antennæ breves, setaceæ; scapo obconico; articulo tertio scapo vel longiore, vel subæquali; quarto breviore; sequentibus brevissimis, obsolete articulatis. Prothorax capite paulo latior, subcylindricus. Elytra oblonga, subdepressa. Pedes breves, æquales. Pro- et meso-sterna declivia. Corpus elongato-ovatum.

The short setaceous, or occasionally nearly linear antennæ not approximate at the base, with the obsolete articulations of the terminal joints—the two apical, especially, looking as if they formed but one—and the somewhat depressed, elongato-ovate outline, will readily distinguish this genus. The type is the Lamia histrio of Fabricius; so at least it is generally stated, but the point must have been determined more by tradition than from his description. Besides Apomecyna cretacea, Hope, there are two forms of this species in collections, or perhaps it would be more correct to say that there are two species under the name of histrio. One, besides other characters, has a thicker scape, the apices of the elytra nearly transversely truncate, and the antennæ unicolorous; the other has the scape smaller, is more thinly covered with pile so that the punctures are readily seen, the apices of the elytra are obliquely truncate, and the fourth joint of the antennæ is generally white, except at the tip. Of the first* I have examples from Dacca and Ceylon; examples of the second, from Bombay and Brisbane (Australia), agree tolerably well together, while those from Batchian and Saylee have much stouter antennæ, and one from Natal is very decidedly broader, with the three series of spots nearer to the apex. Whether these, considering the vast distances which intervene between their respective habitats, are anything more than local sub-species, may be doubted. Mr. Wallace's specimens are identical, I think, with those usually referred to A. histrio, the commonest of the Indian species. The normal Apomecynæ have the third antennal joint twice the length of the scape; a species from South Africa, however, which, in other respects, does not differ generically, has it nearly equal. This I have received under the name of Apomecyna sparsuta, Germ. I cannot find that it has been published. Several insects referred to this genus will have to be separated.

* This may be named A. neglecta.

In habit this genus agrees tolerably well with Sthenias, but differs in a multitude of characters, such as its (apparently) entirely divided eyes, short antennary tubers distant at the base (the space between them nearly flat, not deeply angulated as in Sthenias), and the slightly depressed, not convex, elytra.

SESIOSA.

Characteres ut in Apomecyna, sed oculi divisi, et pro- et meso-sterna elevata.

Of the two differences between Sesiosa and Apomecyna, the first is one of degree only, the second is more important. In Apomecyna the sterna gradually slope down towards one another, and the anterior coxæ are thus more or less widely separated from the intermediate, whilst in Sesiosa, which has the sterna elevated, with necessarily opposing faces, these coxæ are approximate, and a different appearance is given to the pectus. It is necessary to see that the prothorax is neither unnaturally bent on the medipectus nor stretched too much in the opposite direction. One of the examples before me was found by Mr. Wallace "on the branch of a dead tree," another is from Pulo Penang.

The very unusual character, among the Lamiidæ, of truncate palpi will at once distinguish this genus, which in outline resembles Apomecyna. The fore-tibiæ are also remarkable; instead of expanding at the extremity, they contract and are rounded at that part where the tarsi are inserted, and are, in consequence, entirely destitute of the mucro, which is a common character in nearly all the Longicornia. The eyes are unusually large, their lower border extending to the base of the mandibles.

The general appearance of this insect is very similar to Calymmophis flavo-variegata, Thoms. (one of the Mesosinæ), but the head in that genus is very different, and somewhat resembles the Onocephalinæ, i. e. the antennary tubers approximate and have an upward direction. Dymascus is very distinct from anything known to me.

Dymascus porosus. (Pl. VIII. fig. 7.)

D. fusco-pubescens; prothorace linea mediana, elytrisque linea suturali antica maculisque ochraceo-griseis.

Hab.—Singapore.

Pubescent, dark brown, the whole upper surface with numerous punctures; head with coarse greyish and brown hairs; prothorax about equal in length and breadth, the sides slightly round, a narrow central longitudinal line, and a broader one on each side, yellowish-grey; suture greyish, transverse; elytra broader than the prothorax, the sides slightly rounded, each apex somewhat truncate, the suture marked at the base with yellowish-grey continuous with the line on the prothorax, at about the middle of each elytron a semicircular spot, another towards the apex, and externally to the latter a large and more distinct round spot connected with an oblong patch at the side; body beneath and legs reddish-brown, with a thin grey pile, but much thicker and greyer on the tibiæ and tarsi; antennæ with the five thickened basal joints dark brown covered with short hairs, the rest pale grey, becoming darker again towards the tip.

ZORILISPE.

Caput antice transversum, tuberibus antenniferis brevibus. Oculi magni, prominuli, supra subapproximati, infra distantes. Antennæ sublineares, corpore paulo longiores; scapo subelongato; articulo tertio subæquali; cæteris paulo decrescentibus, vel fere æqualibus.

The two species composing this genus have a very similar habit, but differ technically in two or three characters, which however do not seem to be of sufficient value to justify their generic separation. The first species, Zorilispe fulvisparsa, has the eyes very deeply divided, and a longer scape than the other; and is, proportionally, somewhat stouter. The genus is allied to, but quite distinct from, Atimura.

Zorilispe fulvisparsa. (Pl. IX. fig. 8.)

Z. fusca, pube fulvescenti maculata; elytris apice oblique subtruncatis.

Hab.—Sarawak.

Dark brown, with small patches of coarse fulvous hairs; head finely but rather distantly punctured; prothorax scarcely longer than broad, finely and closely punctured; scutellum transverse; elytra with numerous small closely-arranged punctures, each apex somewhat obliquely truncate, the angles of the truncation slightly rounded (in the specimen before me the declivity of the elytra is glabrous, probably from abrasion); body beneath dark brown, closely punctured, with a thin fulvous pile; legs and antennæ brown.

Length 4½ lines.

Zorilispe acutipennis.

Z. brunnea, pube sparsa tecta; elytris apice oblique truncatis, angulo externo acuto.

Antennæ breves, setaceæ; scapo breviter incrassato, basi tenuiori; articulo tertio curvato, duplo longiori; cæteris gradatim brevioribus.

Pro- et meso-sterna declivia.

In Atimura terminata,* the type of this genus, the anterior coxæ are prolonged on their inner edge into a short spine; as this is not the case in the two species described below, I have omitted the character in the above definition. The genus is well limited by its short stout scape, and perfectly cylindrical elytra, truncate at the apex. A. bacillina is almost an exact counterpart, barring a few minute but most important particulars, of the Australian type, and is interesting as a very rare instance of such conformity among the Longicornia. From their cylindrical form, and their colour, these insects resemble little broken twigs or sticks.

Atimura bacillina.

A. griseo-pubescens; prothorace interrupte costato, angulis posticis productis; elytris costatis, apice abrupte truncatis.

Hab.—Sarawak, Sumatra.

Pubescent, greyish, the truncated part of the elytra greyish-white; head and scape closely pubescent, greyish-ochreous, with large black punctures; prothorax moderately punctured, with five obscurely elevated lines, its posterior angles produced, the sides slightly incurved; scutellum rounded behind; elytra irregularly punctured, with four raised lines on each, the innermost interrupted, and terminating in the truncated portion with gradually increasing thickness; body beneath and legs brownish, rather thinly pubescent; antennæ somewhat shorter than the body, slender and slightly pubescent, except the scape.

STHENIAS.

Sthenias, Laporte de Castelnau, Hist. Nat. des Insectes, ii. 466.

Caput antice subquadratum, tuberibus antenniferis validis, elongatis, antice emarginatis, basi approximatis. Oculi modice emarginati. Antennæ corpore breviores; scapo sub-cylindrico, vix elongato, leviter curvato; articulis tertio quartoque longioribus; cæteris gradatim attenuatis et multo brevioribus. Mandibulæ normales, extus curvatæ. Palpi articulo ultimo elongato-ovato. Prothorax capite haud latior, æqualis, cylindricus. Elytra prothorace paulo latiora, cylindrica, convexa, humeris subprominentibus. Pedes breves, robusti; femora vix incrassata; tarsi æquales, articulo ultimo tribus basalibus in unum æquali. Pro- et meso-sterna declivia.

The principal characters to distinguish Sthenias from its allies are the strong antennary tubers and the slender curved scape. The type is an old Fabrician species,* and with this must be placed S. crocatus, Oliv., a Manillan insect, overlooked by M. de Castelnau, but described by Mr. Newman as a new genus and species under the name of Thysanodes jucunda. These, I believe, are the only true exponents of the genus known at present. The individual described below is the only one in Mr. Wallace's Collection; it is much darker than the Indian specimens. Two species described by myself must be separated from the genus as here defined.†

* I cannot reconcile it, however, with the Fabrician description of the elytra, "basi tuberculis duobus elevatis."

† Each of these will represent a distinct genus, which I briefly characterize here, for comparison with Sthenias. The first is—
XYNENON.
Caput antice breve, transversum, tuberibus antenniferis brevissimis. Oculi subfrontales. Antennæ breves, incrassatæ, obsolete articulatæ; scapo breviter subcylindrico, articulis sequentibus vix crassiori. Elytra sub-brevia, basi latiora et convexiora. Pedes validi; femora clavata. Cæterum characteres fere ut in Sthenia.
The type is—
Xynenon Bondii.
Sthenias Bondii, Pascoe, Trans. Ent. Soc. ser. 2, v. 48.
A rosy-grey insect, with brownish stripes anteriorly, and a triangular brownish band across the middle of the elytra.
Hab.—India.
The second genus is—
ANACHES.
Caput fronte prominente, rotundata, tuberibus antenniferis validis, apice extus productis. Antennæ corpore paulo longiores, graciles, setaceæ scapo cylindrico, incrassato, sed basin versus tenuiori; articulo tertio haud longiori. Cæterum characteres fere ut in Sthenia.
The type is—
Anaches dorsalis.
Sthenias dorsalis, Pascoe, Trans. Ent. Soc. ser. 2, iv. 251.
A brown species, with a broad white band across the elytra.
Hab.—India.

Lamia grisator, Fabricius, Ent. Syst. ii. 275; id. Syst. El. ii. 292.

S. fusco-niger; capite prothoraceque lateribus, et fascia submediana elytrorum, grisescentibus.

Hab.—Sumatra.

Brownish-black, pubescent; head and prothorax at the sides, with a well-marked stripe on the vertex, and a broad band rather behind the middle and pointing at the suture towards the base, greyish-white; body beneath dark brown, abdomen greyish, with the last segment black; legs greyish, tarsi and distal half of the tibiæ black; antennæ dark brown, the scape greyish, the third and fourth joints ringed with greyish at the base.

Length 7 lines.

ÆTHOLOPUS.

Caput antice late transversum, vertice elevato, tuberibus antenniferis validissimis, basi contiguis, apice distantibus. Oculi mediocres, late emarginati. Antennæ corpori vix æquales, apicem versus gradatim attenuatæ; scapo crasso, elongato, cylindrico; articulo tertio scapo æquali, apice nodoso; cæteris brevioribus. Mandibulæ angustæ, extus incurvatæ. Palpi modice elongati. Prothorax subquadratus, antice angustior, lateribus rotundatus, angulis posticis rectis. Elytra cylindrica, prothorace multo latiora. Pedes breves; femora fusi-

[page] 161

formia; tibiæ brevissimæ; tarsi vix dilatati. Pro- et meso-sterna depressa.

In some respects this genus may be considered as intermediate between Sthenias and Xylorhiza. All three genera are distinguished by their strong antennary tubers, which, being approximate or even contiguous at the base, create, as they diverge outwards and forwards, a deep hollow in that part of the head between them. From each other they may be distinguished at once by the form of the scape, slender and curved in Sthenias, stout and elongato-cylindrical in Ætholopus, and thick at the apex, gradually contracting towards the base, in Xylorhiza. There are other points of difference, which will be seen on referring to their characters. It may be mentioned that between Sthenias and Xylorhiza, the Comte de Castelnau places nineteen genera. It should be stated, however, that the latter is a most remarkably distinctive genus in habit, although in its technical characters it differs very slightly from Sthenias. The two species of Ætholopus, described below, are very similar, although one is much darker than the other, but the apices of their elytra will at one distinguish them.

Ætholopus exutus.

Æ. niger, subglaber; elytris singulis plagis duabus griseopubescentibus, apice truncatis.

Hab.—Ceram.

Black, nearly destitute of pubescence, except the patches on the elytra; head smooth and somewhat shining, punctures fine and remote; prothorax slightly constricted anteriorly, minutely punctured; scutellum small, transverse; elytra moderately punctured, on each, dividing it into three nearly equal parts, are two large dull-greyish pubescent patches, the apex truncate; body beneath, legs, and antennæ, dark brown, subnitid, the basal joint of the latter strongly punctured.

anteriorly, finely and remotely punctured; scutellum moderate, transverse; elytra with rather small but very distinct punctures, and two large whitish patches on each, occupying nearly the same position as in the first species, but not so marked as they approach the suture, the rest of the elytra more or less shaded with brown, the apex of each shortly but very decidedly divaricate, the outer angle obliquely truncate; body beneath and legs covered with a very fine, close, fawn-coloured pile; antennæ dark brown, the third, fourth, and fifth joints greyish pubescent at the base, the first coarsely punctured.

Length 10 lines.

XYLORHIZA.

Xylorhiza, Laporte de Castelnau, Hist. Nat. des Insectes, ii. 476.

Caput antice transversum, tuberibus antenniferis validis, basi approximatis. Oculi angustati, late emarginati. Antennæ corpore breviores, haud fimbriatæ; scapo basin versus tenuiori; articulo tertio longiori; cæteris gradatim brevioribus. Prothorax capite non latior, inæqualis, antice constrictus, lateraliter spinosus vel inermis. Elytra elongata, prothorace multo latiora, ad latera paulo incurvata, apicibus productolaminatis. Pedes breves; femora fusiformia; tibiæ tarsis haud longiores, intermediæ fortiter emarginatæ. Pro- et meso-sterna depressa.

A grand and well-known species is the type of this genus, but I have so far generalized its characters as to include Xylorhiza spumans (Guér.?) and a few others yet undescribed. Unless we limit Xylorhiza to X. venosa, I do not see how Cymatura, Gerst., is to be distinguished from it, and if we adopt Cymatura (on account chiefly of its spined prothorax), we should have either to refer to it a number of very incongruous species, or to provide for them new genera, which would be hardly more desirable. Latreille gives a very poor figure of the type in the "Règne Animal," iii. pl. xviii. fig. 7, under the name of "Lamie veinée," but it is not mentioned in the text.

Xylorhiza venosa.

Laporte, loc. cit.

X. omnino dense nigro-pubescens, sericea, fulvo-varia et lineata; prothorace mutico.

Hab.—Pulo Penang.

Everywhere covered with a beautiful dense silky pubescence, mostly black, but with clear fulvous lines, especially on the elytra,

[page] 163

where they inosculate towards the apex, the fulvous predominating on the head, the black on the prothorax; on the latter are two fine central lines continued from the vertex, and on each side a still finer line, often bifid posteriorly; the elytra at the base are generally entirely black, then follow stripes of black and fulvous, the proportions varying considerably; body beneath and legs dark chesnut-brown, more or less marked with yellow stripes; antennæ very pubescent, mostly fulvous.

Length 15—22 lines.

PRAONETHA.

Prioneta (ab errore) Blanchard, Voy. au Pôle Sud, iv. 292.

Caput antice subquadratum, tuberibus antenniferis validis, basi approximatis vel subapproximatis. Oculi mediocres, profunde divisi. Antennæ corpore breviores, rarissime in maribus longiores, setaceæ, subfimbriatæ; scapo cylindrico vel subcylindrico; articulo tertio longitudine scapo æquali, rarius longiori vel breviori, subcurvato, apicem versus gradatim incrassato;* quarto simillimo vel subæquali; sequentibus sensim brevioribus; articulorum apicibus aliquando productis, vel spinosis. Prothorax capite latior, plus minusve subquadratus, ad latera subrotundatus, vel subparallelus. Elytra subbrevia, convexa, sæpissime compressa, generaliter supra inæqualia. Pedes mediocres; protibiæ fere rectæ, rarius paulo curvatæ, intermediæ haud emarginatæ; tarsi æquales. Pro- et meso-sterna modice elevata.

The diversity of form to a certain extent of many of the species here brought together may, no doubt, be objected to, but, after a careful examination, I cannot see that anything like a satisfactory limitation can be established even in dividing them into sections, although I have attempted to do so, but solely with a view to facilitate their descriptions. The whole, when fairly compared, and not putting extremes into juxtaposition, will, I think, be found to compose, considering its great extent, a tolerably homogeneous group, which a practised eye will at once distinguish.

*The following, described by me as a Praonetha, must be separated from it to form a new genus.
DESISA.
Characteres ut in Praonetha, sed oculi modice emarginati: antennæ corpore longiores, tuberibus antenniferis basi distantibus, articulis cylindricis, rectis, apicibus haud productis vel incrassatis.
The type is Praonetha subfasciata (Journ. of Entom. i. 348). It is from Cambodia.

[page] 164

So far as my materials have allowed, I have had little doubt as to the distinctness of most of the species here described; the technical characters are, however, so slight in themselves as to make very decided diagnoses impossible. The colours of the derm are brown of various shades, with a pubescence of grey of various shades, modifying each other according to the density of the latter, with spots or patches or lines, more or less distinct, or mere shades of more or less intensity. Some individuals are darker than others, or their markings may be nearly obliterated, so that it is very difficult to say what characters are to be relied on; or, if a larger series of specimens were available, it might be that many forms here described would be found to belong to one variable species.

On those species with crested elytra Mr. Newman has formed his genus Pterolophia* (and Notolophia), but in some the crests are so slight that it is hard to say if they really exist; the passage is almost insensible.†

Respecting the habits of these insects, Mr. Wallace say that they are found in large numbers on the tops of bamboo palisades, used in fencing, whenever there is any moisture oozing from them.

§ 1. Elytra scarcely, or not at all, crested, the apex rounded.

* An undescribed species from Hong Kong, also with a very slight basal crest, may be noticed here. I have named it after Mr. Bowring, to whom the nation (which I am afraid very inadequately appreciates the gift) is indebted for the magnificent collection which has added so largely to the value of the Insect Department of the British Museum.

This is a fine, robust species, and, except P. scopulifera (ante, p. 175), is the only one of the genus having numerous small tufts on the elytra.

STESILEA.

Characteres ut in Praonetha, sed prothorax antice vix angustior, et elytra magis elongata, depressa, semper æqualia.

Although the technical characters of this genus are not very definite, it is, nevertheless, a very natural one, and, but for the absence of the small anterior prothoracic tooth, might have been referred to the Niphoninæ. The species are all very homogeneous in point of size and colour, but the spots on the elytra may probably prove to be an uncertain character.

A number of small and obsurely marked species are comprised in this genus; they are on the whole tolerably homogeneous, although the short compact from of the majority is departed from in a few of its members. The transition is, however, gradual, as usual, and there is no other character to separate them. The scape of this genus is variable in size, and there is somtimes a slight but sufficiently obvious difference even in the same species. The head and prothorax are generally strongly, although rather finely, punctured; the punctures on the elytra are much coarser, and are occasionally subseriately arranged, but only in the centre of the disc; the pubescence, except on the head, is strictly confined to the spaces between them. The genus is only represented at this time in Australia by a single species (Ropica exocentroides, Pasc.).* Oopsis, Fairm., restricted to the Fiji and other Pacific Islands, is known by its strongly clavate femora.

MEXIMIA.

Characteres ut in Ropica, sed antennæ lineares, haud fimbriatæ

It is impossible to retain the species on which this genus founded in Ropica, without violating a character which is constant throughout the latter group. The scape, variable in Ropica, is, in the two species described below, shortly ovate, but the coloration and apparent glabrosity (for the pubescence is visible only under the microscope) give them quite a different habit. The punctures on the prothorax and elytra are, as in other members of the subfamily, furnished at the base each with a triangular scale-like hair.

The general outline of the species of this genus is different from Ropica, being more elongate and fusiform and very decidedly

[page] 199

depressed above. The characters, although not very decisive, are tolerably constant for so large a group. The type, Sybra stigmatica, is nearly allied to a Madagascar species—the Saperda geminata of Klug. I have divided the genus into three sections, the first having the apex of each elytron brodly wedge-shaped, and the sutural side of the wedge with a convex outline; the second section has a narrower and more projecting wedge, and the sutural side more or less concave; the third section has each elytron rounded at the apex. Sybra incivilis, Pasc., from Port Densison and S. posticalis, Pasc., from Hong-Kong, belong to the first, and S. acuta* from New South Wales, to the second. The first, and by far the largest, section is divided into subsections dependent on the comparative breadth of the prothorax at the base. The species are all of small size, with a derm varying from testaceous to dark brown or nearly black, and covered with a generally scanty greyish pubescence, almost invariably relieved by spots or patches of white, grey or brown, but often so indistinctly as to require a strong lens to distinguish them. Unfortunately there is reason to believe that the species vary considerably among themselves, and particularly that a minute description of the coloration would only be applicable to certain individuals; at the same time the distinctions to be drawn from form and sculpture are not always sufficiently decided to allow of their being clearly stated. With a large number of examples, I can conceive that it might be impossible to divide them satisfactorily at all. In fact I have put aside several that I can neither resolve into species or quasi-species, nor refer to any here described. In two or three instances in which Mr. Wallace has marked the sexes of the same species, the differences between them consist chiefly in the broader prothorax and somewhat longer antennæ of the males.

MYNONOMA.

Characteres ut in Sybra, sed pedes, præsertim postici, multo longiores, et tarsi tibiis breviores.

A few of the species of Sybra have their tibiæ slightly longer than their tarsi, but then the legs are all equal or nearly equal in length; but in this genus there is a marked departure from that type, and indeed from the sub-family, the intermediate and particularly the posterior pair being very decidedly longer. The coloration and sculpture are, however, the same as in Sybra. The only representative at present of the genus has a certain resemblance to Eunidia nebulosa, Er., which has suggested the name.

A very distinct genus, allied in some of its characters to Sybra, but differing in habit, with longer legs and antennæ, and presenting another system of coloration, resembling in fact some species of Tmesisterninæ. It might be, perhaps, referrible to the Saperdinæ but for its strongly emarginate mesotibiæ.

Note.—M. J. Thomson has a genus Sydonia in his Systema Cerambycidarum, p. 45, which appears to be allied to Zorilispe (ante, p. 156), but the characters "prothorax later. sinuatus" and the elytra "postice dehiscentia" are not applicable to it. The species is thus described—

"Type: Sydonia apomecynoides, Thomson.

DORCADIONINÆ

Only two species of this sub-family occur in the Wallacean Collection, both having a very close resemblance to the European genus Parmena. No doubt many more forms remain to be discovered, as the Asiatic and Australian members of this group are amongst the rarest of insects known, and whilst new species occasionally occur, it is rare indeed to see a second example of an older one. They are probably for the most part nocturnal insects like Parmena, lurking by day under stones or fallen trees, or in hollow stems of plants, rarely straying far from their hiding-places, in which their race, in some cases,* have probably existed from the time before the earth received its present form.

One of the peculiarities of this sub-family is the power which many species possess of making a creaking sound when seized or disturbed. This sound is produced by the movement of the prothorax on the mesothorax, which, at that part, appears to be perfectly smooth, but under the microscope is seen to be transversely striated. It seems to me that these sounds are naturally caused by the attempts of the insect to escape, and that it is not a power given as a means of protection to frighten its enemies.

The rounded or obsolete shoulders, always connected with the absence of wings, or at most the presence of very rudimentary ones, is the principal feature of this sub-family, which otherwise varies considerably. The typical form appears to be the genus Phantasis of M. J. Thomson, leading away on one side to Microtragus, Athemistus, Dorcadion, Parmena, &c., and on the other to Blax and Xylotoles through Deucalion, Dorcadida, Brimus, and Phrissoma. Hoplonotus, Auxa, Aconodes, and a few other, must stand for the present as more or less isolated forms.The

* Mr. Wollaston (Insecta Maderensia, pp. 430 et seq), in an interesting account of the discovery and habits of Deucalion desertarum, says, "When we consider indeed the apterous nature of Deucalion, its subconnat elytra, and its attachment (at any rate in the larva state) to the interior of the stems of particular local plants, or its retiring propensities within the crevices of rocks, we are at once struck with the conviction that, during the enormous interval of time which has elapsed since the mighty convulsions which rent asunder these regions terminated, it has probably never removed many yards from the weather-beaten ledges which it now inhabits." Another species, which Mr. Wollaston has referred to the same genus (D. oceanicus), was found on one of the Salvages, a mere cone of rock in the midst of the ocean, and must have existed there before the Atlantic islands became detached from the great continental land, of which they once formed part.

[page] 223

affinities of the Dorcadioninæ appear to be chiefly between the Apomecyninæ and the Lamiinæ: the genus Blax showing a tendency towards the Tmesisterninæ. Several species betray a striking resemblance to genera of the Curculionidæ inhabiting the same countries with themselves.

The geographical distribution of the Dorcadioninæ is somewhat peculiar, inasmuch as only one species (Taurorcus chabrillacii, Thoms.) has as yet been found in South America, except Chili, where Hoplonotus and Microcleptes appear to be common. Mexico and Texas have Moneilema and Echthistatus, and California has Ipochus. In Europe we have only two genera, Dorcadion and Parmena. Africa has some very remarkable forms, as, for example, Oriœthus, Opsies, Stenoparmena, Auxa, &c. (the last from Madagascar). From Asia we may expect many novelties; at present we may mention Dorcadida, Morimopsis, Plectrura and Aconodes.* Others in collections are not yet described.

There appear to be only two Australian genera—Microtragus and Athemistus,† but there is reason to believe that they are both numerous in species. New Zealand, so excessively poor in its specific forms of animal life, is comparatively well represented. Here, and peculiar to those islands, are Cerægidion, Hexatricha, Xylotoles, and Somatidia, all isolated forms so far as New Zealand is concerned, although the last is closely allied to the European Parmena. Islands, and probably also mountain masses of low elevation, appear to be particularly favourable to the existence of members of this group. Thus from Madeira and the Desertas we have Deucalion, from the Canaries Lepromoris‡; Lord Howe's Island gives us Blax, and New Caledonia Tricondylodes.

The species collected by Mr. Wallace form two

Genera.

* This genus is only known from one example (now in the British Museum). It was found in the Himalayas, near Darjeeling, I believe. There is another form from the Neilgherries. The hill-districts of India have doubtless many more.

† I believe, however, that my genus Mesolita will be eventually referred to this sub-family.

Lepromoris, Pascoe, Journ. of Entom. ii. 278 = Leprosoma, Thomson, (non Baerensprung) = "Brullea, Bld." (sec. Chevrolat), "Brullaria" in the collection of the Jardin des Plantes, according to Mr. Wollaston. Neither of these two latter names has been published so far as I can ascertain.

DASYERRUS

Caput antice latum, tuberibus antenniferis validis, distantibus. Oculi parvi, profunde emarginati. Anfennæ corpore breviores; scapo breviusculo, subcylindrico; articulo terio longiore; cæteris sensim brevioribus. Prothorax subquadratus, lateribus antice dentatus. Elytra ovata. Pedes robusti; femoro medio incrassata; tibiæ intermediæ integræ; tarsi æquales. Pro- et meso-sterna elevata.

The type of this genus is very much like a large unicolorous specimen of Parmena Solieri. The genus is, however, sufficiently distinct from Parmena* on account of its prothorax, sterna and intermediate tibiæ. The anterior acetabula are broadly angulated externally.

Dasyerrus pilosus. (Pl. X. fig. 8.)

D. fuscus, dense griseo-pubescens, pilis numerosis elongatis dispersis.

Hab.—Flores, Timor.

Dark brown, covered with a dense greyish pile, slightly mottled with fulvous, and having numerous slender hairs scattered over the upper surface, legs, and antennæ; head narrower than the prothorax, thinly punctured in front; prothorax coarsely punctured, nearly quadrate in the Flores specimen (♂), more transverse in the Timor one, which is apparently a female; scutellum semicircular; elytra oblong, rather wider than the prothorax, coarsely punctured, slightly rounded at the sides, the shoulders nearly obsolete, the apex rounded; body beneath and legs dark brown, sparingly pubescent, the tarsi ashy; antennæ scarcely so long as the body in the male, much shorter in the female.

Length 4½ (♂)—5½ (♀) lines.

* This genus is generally attributed to Latreille (Règ. An. v. 125). He, however, does little more than quote the name, which was a catalogue name of Megerle's, mentions no species, and so far attempts to suppress it, that he asserts that such very different species as "tristis, lugubris, funesta" (now forming the genus Morimus) "offer the same characters"!!! The first description is really due to Serville, in Ann. Soc. Ent. de France, iv. 98 (1835). The type P. pilosa (Dej.), Serv., had its name, I venture to think, most unnecessarily changed by M. Mulsant, because there is a Pogonocherus called "pilosus." It so happened, however, that two years before Serville published his description, Brullé had described another species under the same name. This, therefore, retains the name, while Serville's pilosa must be replaced by Mulsant's "Solieri."

BYBE.

Characteres ut in Parmena, sed prothorax subquadratus, lateribus muticis et leviter rotundatis, et elytra breviter ovata, medio valde convexa.

The prothorax in Parmena, although somewhat variable, always shows traces of the lateral tooth; the elytra, however, never rise beyond the line of the prothorax, and are always elongate-ovate. The curious little insect forming the type of Bybe is somewhat intermediate in appearance between Parmena and Microcleptes.

The following genus is of somewhat doubtful affinity; I insert it provisionally at the end of the Dorcadioninæ:

Prosternum haud elevatum. Mesosternum dentatum.

M. J. Thomson places this genus in his "groupe Mesositæ,," between Aderpas and Anamera,* (the latter, I conceive, belonging to the Lamiinæ); the habit, however, the peculiar sculpture of the elytra, and particularly the lobed base, together with the short dense squamosity, so characteristic of the Dorcadioninœ, seem to me rather to suggest the latter sub-family, notwithstanding its humeral angles, and the possession of wings. There is an undescribed genus in the British Museum from North china, which might, at first sight, be taken for a Trachystola, but which is also so suggestive of Phantasis (an African form of Dorcadioninæ), that Mr. White has placed it in immediate connexion that genus. Admitting the difficulty of locating Trachystola for the present, I have little doubt its true place will be with the Dorcadioninæ. M. Thomson's species (T. scabripennis) is from Java, and may possibly be distinct, at least a specimen from the same country in the British Museum, if identical with M. Thomson's type, is sufficiently characteristic to be so considered.

Trachystola granulosa.

Length 10—11 lines.

HYPSELOMIÆ.

The genus which gives its name to this sub-family is exclusively confined to South America, and was generally supposed to be synonymous with Hypsioma, Serv., until the difference was pointed out by Messrs. Thomson and Bates. Hypselomus, Perty, is, however, a somewhat aberrant genus, and it would therefore have perhaps been better to have called the group Hypsiominæ, were it not that M. Thomson has a "division" Hypsiomitæ limited exclusively to the South American species. Mr. Bates places these genera with Oncideres.

The principal character of this subfamily is the approximate and almost contiguous position of the antennæ at their base, a character which, except in Hippopsinæ, is only occasionally met with among the Lamiidæ. To this is generally added a long, stout, more or less cylindrical scape, a trigonate form of elytra, which are crested or otherwise raised at the base, legs of moderate length with thickened or clavate femora, and tarsi invariably of equal length or nearly so. Except in the South American genera, the mesosternum is almost without exception elevated and produced, or toothed. Among the Asiatic and Australian forms only four genera have the prothorax unarmed.

None of the species of this sub-family are found in Europe, and Acridocephalus, Chev., is the only African genus known to me that can be referred, and that not altogether definitely, to it. All the Asiatic* and one Australian genus are represented in the collection, which contains nineteen genera† and thirty-seven species. Of the Australian genera, Zygocera, Callipyrga, Demonassa, and Meton, are among the most prominent; the last, alluded to above, has a species from Asia.

* There is a form, however, from Northern India, described by M. Thomson (Arch. Ent. i. 294), under the name of Monochamus subgemmatus, which appears to me to belong to this sub-family, and to be very nearly allied to Pharsalia, and with difficulty distinguishable from it by any definite technical characters. The antennæ of the males are shorter and less setaceous, the scape stouter, and the femora narrower; the mesosternum is also prominently toothed anteriorly. In my collection it has long stood under the generic name of Cycos. (See Proc. Zool. Soc. 1866, p. 244.)

† Exclusive of Lælida (post, p. 257), which probably belongs to this sub-family, though its true position is at present doubtful.

ACHTHOPHORA.

Achthophora, Newman, The Entom. i. 292.

Stegenus, Pascoe, Trans. Ent. Soc. ser. 2, iv. 104.

Caput antice supra angustius; tuberibus antenniferis validis, erectis, contiguis, apice intus productis. Oculi parvi, ore remoti. Antennæ corpore vix longiores, articulis (ultimo excepto) cylindricis, quatuor basalibus aliquando hirsutis; scapo mediocre; articulis tertio et quarto longioribus; cæteris brevioribus et gradatim decrescentibus, ultimo subulato, curvato.

When I proposed Stegenus I stated that it differed from Achthophora chiefly in its antennæ, the first four joints being clothed with stiff hairs instead of only the apex of the fourth. In other respects it agrees so closely with Achthophora, that after a renewed comparison, I think it is desirable to unite them. Achthophora alma has the prothoracic spine tolerably well developed; it is smaller in A. tristis, the type, and least of all in A. dactylon, in which it is scarcely noticeable. Mr. Newman considers that A. alma may be only a variety of A. tristis, but the typical specimens, which are the only ones I am acquainted with, do not in my opinion justify such a conclusion. A. dactylon, which is apparently rare in Borneo, seems to be a common species in Penang. The other two are from Manilla. My original specimen was entirely of a dark brown, except the apex of each elytron, which had a peculiar finger-shaped patch of buff, but all those from Penang have numerous small very clear spots of yellow on the elytra, and some indications of paler or more greyish spots elsewhere, particularly on the prothorax.

A very natural genus, distinguished from Pharsalia by its antennæ, and their diverging tubers not produced internally, and from Cereopsius by the form of the prothorax, the lobed shoulders &c. Monohammus larvatus, White (Proc. Zool. Soc. 1858, p. 406) also belongs to this genus. P. pubicollis appears to be common at Penang.

These characters are drawn up from the three species collected by Mr. Wallace. A nearly allied genus from Penang (Omocyrius) differs in the oblong prothorax, the altered proportions of the joints of the antennæ, and the fourth and fifth being thickened throughout in both sexes, the third also in the female is nodose at the apex: in addition it has the shoulders produced as in Otarionomus and Achthophora. So far as the individuals I have seen can be relied on, the males of T. Saundersii and T. tristis are smaller than the females, but this is reversed in T. Chevrolati All the species have numerous glossy-black granulations of varying size on the basal part of their elytra, as well as a broad white band on the cheeks, sides of the prothorax, and sterna. A female specimen from Batchian, which I cannot refer to any of the above, although it approaches T. tristis, has the scutellum equilaterally triangular, not broadly truncate, or broadly rounded, as in the other species.

The sole representative of this genus was originally described by me as a "Monohammus," although at the time I ventured to suggest a doubt of its really belonging to that group. Monohammus, or rather Monochamus, was, and is at this moment, a mere name, under which

[page] 235

many very distinct forms have been conveniently but unnaturally placed. M. James Thomson has since proposed new genera for a few of these, and further on I shall have many more to describe. Such genera may be, and often are, very difficult to limit, but they exist as categories of species, and when not solely founded on technical characters, they are an advantage to the real student. Of course to those who would fain pursue "the royal road" they are simply a bore. Otarionomus is a very distinct genus, and, as its author has pointed out, is very nearly related to Triammatus, and this is still more evident since the discovery of Omocyrius. There are certain discrepancies both between M. Thomson's descriptions and my own original one and that here given; my original specimen, however, has a very different look from one of the magnificent insects now before me, and from which I have drawn up the present article.

[page] 237

The type of this genus was referred by Mr. White to Cereopsius, but the large head and smaller eyes, together with the form of the prothorax, strongly constricted at the apex and base, and the nearly central position of the spine, are at variance with the characters laid down for that genus. The figure of this handsome insect given by Mr. White does it very scant justice.

By the removal of Othelais and Etymestia this genus is now intelligibly limited, although one of its species (C. marmoreus), from its shorter legs and more elongate form, is somewhat aberrant. One of the unpublished species, C. Saga (Dej.), has, however, the elytra rounded at the apex.

This is rather a degraded form of the genus, but still preserving all its characters, except that the disk of the prothorax is less irregular. It, however, undoubtedly tends to obscure the line between Cereopsius and Xoes.

DIALLUS.

Characteres ut in Cereopsio, sed antennæ articulo tertio scapo breviore; prothorax dorso regulari, spina laterali retrorsa; elytra apicibus rotundatis; et mesosternum latum, antice transversim dilatatum.

A sufficiently distinct genus, easily distinguished from Cereopsius, as well as from Othelais and Otroea, which it also resembles in habit, by the short third joint of the antennæ. The prothoracic spine, although directed backwards, is not recurved as in Othelais. The cicatrix on the scape is smooth and shining. The species are tolerably homogeneous, rather below the middle size and spotted with white on a dark ground.

This genus approaches Othelais and Diallus in habit and in many of its characters; from both it is distinguished by the short straight spine of the prothorax, and the broadly-transverse joints of the anterior tarsi. The three species described below are very distinct in coloration, but the sculpture is very similar, especially of the first two.

A narrower form than any other of the sub-family, and differing also in the shorter scape, the relative proportions of the antennal joints, and the form of the prothorax.

Pedes modice elongati; tarsi postici paulo longiores Prosternum sub-elevatum. Mesosternum productutumm, medio carinulatum.

The absence of the cicatrix on the scape and the coarsely facetted eyes will at once distinguish this genus. This character of the eyes also occurs in Amesisa and one or two other genera, in conjunction with a cicatricose scape.

AGNIA.

Agnia, Newman, The Entom. i. 291.

Pedes (præsertim ♂) modice elongati; tarsi sub-æquales. Prosternum elevatum. Mesosternum valde productum.

This handsome genus will be readily recognized, at least among those in this collection, by the obconical form of the prothorax, which is without any trace of the lateral tooth, and by the long setaceous antennæ (varying however from twice to four times the length of the body in the same species) as contrasted with Achthophora.

The characters of this genus, as well as the species that compose it, have nothing about them very decided. Nevertheless the genus is a tolerably natural one, and the species very distinct. I am not, however, acquainted with the type (P. Malasaica), but I have received from M. J. Thomson P. gibbifera, Guér.,* to which it appears Monohammus? agenor, Newm., is to be referred, and with this I have little difficulty in connecting the species described below as congeners. P. cincticornis is a female specimen and may possibly be P. Malasaica, Thoms., but that author omits all mention of the antennæ. The colours of these insects are a mixture of various shades of grey and brown, and sometimes ochraceous; and the elytra have each two raised lines, which are more prominent posteriorly.

Pharsalia lentiginosa.

Another specimen, which is probably the female of this species, has much darker colours, with the ringed pattern on the elytra scarcely recognizable.

Hab.—Sarawak, Singapore.

Brown or purplish brown, with a short interrupted fawn-coloured pubescence spotted with ochraceous; ochraceous spots round the eyes and two stripes on the vertex; prothorax impunctate anteriorly and posteriorly, the central part with small, rather distant, punctures, with one or two ochraceous stripes on each side, which are sometimes obsolete; elytra without crests at the base, rounded at the apex, varied with indefinite fawn-coloured patches, which are sometimes nearly obsolete, and with more coarsely pubescent ochraceous spots, which are especially massed together on the posterior third of the elytra; body beneath and legs with a grey pubescence, sides of the abdomen spotted with ochraceous; antennæ pale brownish, darker towards the tips.

Length 7 lines.

In this somewhat aberrant species the elytral gibbosities have disappeared, but the lateral prothoracic spine is well marked.

COMBE

Combe, J. Thomson, Syst. Ceramb. p. 83.

Characteres fere ut in Cereopsio, sed oculi parvi, ore distantes: antennæ (♀) longissimæ; scapo mediocre, apicem versus crassiori, apice valde cicatricoso, articulis tertio et sequentibus (?) multo longioribus, cylindricis, incrassatis, (♂) corpore paulo longiores, articulis cylindricis sed vix incrassatis, a tertio sensim brevioribus et tenuioribus; prothorax basi quam apice haud latior, spina laterali in medio sita; elytra magis depressa.

The females of the handsome species which is the only exponent of this genus are, according to the specimens now before me, very considerably larger than the male, but the antennæ are not much longer than the body. Unfortunately the only male I have seen wants the last six joints of the antennæ, but the fifth joint is longer than the fourth, and this again longer than the third; the contrary of this occurs in the female, from which sex only M. Thomson appears to have drawn his description. The specimen in the British Museum described by Mr. White is without a head. There are no granulations on the elytra, as in Triammatus.

The short, sub-cylindrical, nearly mutic prothorax, in conjunction with the long antennæ and simple mesosternum, will readily distinguish this genus, which is otherwise of a commonplace appearance. Its affinities are not very obvious.

In characterizing this genus in the work above quoted I placed it between Monochamus and Dysthæta, but on examining it afresh I think its affinity (as well as that of Dysthæta) is more with the present sub-family, particularly in regard to its clavate femora. None of the species, however, with which we are acquainted, seem suggestive of any affinities; and the genus, like many others of this and other groups, can only be regarded as somewhat aberrant. The genus has two well-marked species in Australia (M. Digglesii, Pasc., and M. tropicus, Pasc.).

Unfortunately the unique specimen before me wants the last five joints of the antennæ, and therefore I have not figured it. It resembles in outline a Criopsis or a Scleronotus, and is well characterized by the long claviform third antennal joint, followed by others so much smaller and slenderer (although the fourth is less so than those which follow) as to give them the appearance of having belonged to another insect.

M. J. Thomson has separated this and two other species from Zygocera, to which I had referred them, to form three genera. This, however, is the only one which occurs in the Malayan Fauna, and is distinguished from Zygocera by its transverse face and the anteriorly-dilated prosternum extending more or less in front of the anterior coxæ. The latter character it has in common with Disterna—another of the three genera alluded to,—and from this it scarcely differs, except in the form of the head anteriorly.

Length 5 lines.

The following genus, in the great length of the antennæ and the short feet, seems to approach Hippopsis; but the shortness of the sterna and the cicatricose scape forbid any association in that direction; there is an analogy, at least, between this genus and Otroea, in the breadth of the anterior tarsi, and the approximation of the antennary tubers is significant of its probable affinity to the Hypselominæ.

LAMIINÆ.

After a careful examination I have come to the conclusion that no sufficient differentiation can be made between Lamiinæ, Monochaminæ and Gnominæ, and that to obtain anything like a satisfactory set of characters it would be necessary to form a large number of groups, or, as we would call them for the sake of uniformity, "sub-families." It may seem a violation of all our ordinary ideas of natural affinity to place Gnoma with Petrognatha, Cylindrepomus with Tragocephala, or Lamia with Gerania, yet such are the extreme varieties of form and so graduated the characters by

VOL. III. THIRD SERIES, PART III.—SEPT. 1866. S

[page] 258

which we attempt to fix them that it is only a choice between the combination of the most heterogeneous genera, or the addition of numerous sub-families,* which would also, many of them, contain exceptional forms. With few exceptions this evasive variation seems to bethe rule throughout the Longicornia, and this makes their classification so difficult. By strictly limiting the more obviously allied species to the same genus the difficulty is obviated in them, but we should lose some of the advantages of classification if this principle of himogeneity were to be carried into the higher groups.

To give any but the most general remarks on this sub-family, the extensive signification which is here given to it, would be almost impossible; nearly every extreme of colour, form and size are represented,—some are among the giants of the insect class, some are remarkable for their long antennæ, or their short legs, or for a combination of both. The majority of them, however, have a form of which the common European Monochami will give a central idea, from which the aberrant genera depart by gradual modifications, not always, indeed, without a break.

The affinities of the Lamiinæ are very decided. To Hypselominæ, especially to such genera as Triammatus, Omocyrius, Pharsalia and others, there is the strongest resemblance; Lamia, Morimus, &c., recall the Dorcadioninæ; and Nemotragus and Anauxesis lead by Megacera to the Hipposinæ.

The geographical distribution of the Lamiinæ, when we consider their numbers, may be said to be almost exclusively confined to the African, Indian, and Malayan regions. Europe and America, north of Mexico, have only the genera Monochamus, Morimus, Lamia, and Plectrodera; the two principal genera of tropcal America are Tæniotes and Ptychodes; Monochamus again and Batocera are the only exponents in Australia, and the presence of the latter genus, except as introduced, is doubtful, although it may perhaps be found to occur in the extreme north of that continent. Thysia, Oplophora, and a few other genera, occur in India and China. The headquarters of the sub-family a are undoubtedly the Malayan islands, but if we take the African Longicornia, and compare the Lamiinæ with the other sub-families, they will be found to be by far the predominant group.

* I would particularly mention the following genera as the types of some of these groups:—Petrognatha, Ceroplesis, Tragocephala, Sternotomis, Pkryneta, Ancylonotus, Gnoma, Olenecamptus, Nemotragus, &c. In M. J. Thomson's "Systema Cerambycidarum" many of these form "divisions."

[page] 259

The African genera are, however, very distinct and have scarcely anything in common with the Malayan.

One hundred and ten species occur in the Wallacean collection, which I have distributed into twenty-eight genera. In the following tabulation it has been necessary to adopt characters some of which separate at a long interval nearly allied genera.

BATOCERA.

Batocera, Laporte de Castelnau, Hist. Nat. Ins. ii. 470.

Caput antice sub-transversum; clypeo distincto, supra arcuato; tuberibus antenniferis validis, divergentibus, basi contiguis. Oculi magni, profunde emarginati, parte inferiori os fere attingente. Antennæ (♂) sæpe corpore duplo longiores, scabræ, vel denticulatæ, articulorum apicibus aliquando spinoso-productis, (♀) breviores, minus rugosæ vel denticulatæ scapo valido, apice incrassato et valde cicatricoso; articulo tertio cæteris multo longiori; sequentibus sensim brevioribus. Prothorax transversus, utrinque fortiter spinosus, basi bisinuatus, antice et postice transversim corrugatus. Elytra oblonga, apicem versus sensim attenuata, (♀ magis ovata), apicibus truncatis, sæpissime bispinosis, humeris productospinosis. Pedes longiusculi; femora sub-linearia, antica (♂) scabra; tibiæ anticæ curvatæ, (♂) subtus denticulatæ tarsi breves, articulis tribus basalibus triangularibus, antici (♂) articulo primo extus producto, ultimo præcedentibus fere æquali. Pro- et meso-sterna simplicia. Abdominis segmento ultimo (♀) supra sæpissime detecto.

M. de Castelnau includes Anoplosthæta and Plectrodera in this genus, and consequently he is unable to take advantage of the very decided characters afforded by the antennæ and elytra, which at once distinguish Batocera from all the other genera in this sub-family. Batocera rubus, Lin.,* the type, is found all over the East Indies, and extends from the Isle of France to Australia, (in the latter country, however, probably introduced, as it has been in Europe), but, oddly enough, it does not seem to have been met with by Mr. Wallace. The genus is one of the finest among the Coleoptera, B. Wallacei sometimes measuring eleven inches in length from the hind tarsi to the extremity of the antennæ; but at the same time, owing to various modifications of colour, it is one of the most difficult in regard to the differentiation of the species; in many cases it is impossible to distinguish them without the aid of a suite of specimens. The species are mostly found on fallen timber; and they fly about in the evening as well as in the hottest sunshine.

* M. Kaup (Einige Ceramb. &c.) considers the Lamia rubus, Fab., to be distinct from the Linnæan species, and has named it Batocera Wieneckii.

Prothorax bimaculatus.

Batocera octomaculata.
Lamia 8-maculata, Fabricius, Ent. Syst. ii. 290.

Batocera Sararvakensis, J. Thoms. Arch. Ent. i. 452, pl. xix. fig. 2.

B. fusca, griseo-pubescens; scutello elytrisque maculis 8—10 niveis; horum apicibus oblique truncatis, angulo suturali mediocriter spinoso, angulo externo parum producto.

Hab.—Malacca, Sumatra, Borneo, Java, Banda.

Pale reddish-brown to dark brown, with a delicate uniform greyish or yellowish-grey pubescence; head impunctate, a pale yellowish rim round the eyes, with small black granules at short intervals; antennæ slightly pubescent, apices of the joints from the fourth to the eighth with two short spines, the ninth slightly dilated on one side; prothorax transverse, the breadth, including the spines, nearly twice the length; scutellum white; elytra of intermediate length, with four snowy-white spots in the middle line of each, more or less equally distant from each other and the base and apex, the second generally the largest and often accompanied by a smaller spot external to it, shoulders with a short spine directed outwards, apices slightly obliquely truncate, the sutural angle terminating in a moderately short spine, the outer angle only slightly produced, not spinous; body beneath pubescent, grey, a broad snowy stripe extending from the eye along the sides of the prothorax and sterna to the fourth abdominal segment; legs with a delicate grey pubescence.

Length 11—20 lines.

I have been unable to find any character to separate B. octomaculata and B. Sarawakensis, and am very doubtful as to the claims of the next following.

Batocera Celebiana.

J. Thomson, Arch. Ent. i. 453, pl. xx. fig. 1.

B. fusca vel nigro-fusca, griseo- vel ochraceo-pubescens; scutello elytrisque maculis 6—8 niveis; horum apicibus sinuatis, angulo suturali mediocriter spinoso, angulo externo parum producto.

Hab.—Tondano, Menado, Macassar.

The only character I can discover to distinguish this from the last is the sinuate apex of the elytron; I am not sure that it is per-

[page] 263

sistent. M. Thomson's description is from a female, of which he says that is "more robust and shorter" than the preceding.

Length 12—25 lines.

Batocera Thomsonii.

Javet, Arch. Ent. i. 412, pl. xx. fig. 2.

B. fusca, obscure griseo-pubescens; scapo (♂) basin versus rugoso; scutello elytrisque maculis 4—6, præcipue duabus in medio maximis, niveis, apicibus truncatis, angulis spinosis, (♀) minus productis; tibiis anticis (♂) modice elongatis.

Hab.—Sarawak, Singapore, Penang.

Dark brown, with a dull yellowish-grey pubescence; scape (in the males) roughly punctured at the base, the intervals rising into short irregular folds; other characters as in B. octomaculata, but the third joint of the antennæ is considerably longer in both sexes, and, in what are apparently the normal specimens, there is only one large spot in the middle of each elytron, with perhaps two or three mere points, not always the same number on both sides; the exterior spine at the apex is as large as the sutural in the male, and is only a little less so in the female; the fore and intermediate legs are also more robust and longer than in the preceding.

Length 15—24 lines.

Batocera Victoriana.

J. Thomson, Rev. et Mag. de Zool. 1856, p. 529; Arch. Ent. i. frontispiece.

B. ferruginea, tenuiter griseo-pubescens; scapo basin versus punctato, vix rugoso; elytris sub-elongatis, maculis plurimis flavescentibus vel miniaceis, basi nebulosis; tibiis anticis (♂) elongatis.

Hab.—Sarawak.

Reddish-ferruginous, with a thin uniform greyish pubescence; head and prothorax as in the preceding; scape closely and coarsely punctured at the base, but scarcely rugose; fourth joint of the antennæ (♂) with a strong spine at a right angle with the apex, fifth, sixth and seventh with a triangular short spine tipped by a short mucro, eighth and ninth also spined, but not mucronate; scutellum white; elytra rather elongate, with several pale yellowish or occasionally bright vermilion spots, the base clouded with yellowish; body beneath greyish or brownish, pubescent, the

[page] 264

broad lateral snowy stripe not extending beyond the first abdominal segment; anterior legs and especially the tibiæ elogate.

Length 28—30 lines.

The spots on this very distinct species are, I believe, always of a bright vermilion when the insect is living, and one of my specimens still retains that colour. It is longer and narrower than any of the preceding.

Batocera metallescens.

B. fusco-metallica, tenuiter ochraceo-pubescens; scutello griseotomentoso; elytris cuneato-elongatis, in medio macula irregulari albo-tomentosa impressis.

Hab.—Macassar.

Dark brown, with a strong metallic gloss and a rather thin ochraceous pubescence; head and prothorax as in the preceding, but the latter less pubescent; antennæ more decidedly punctured and less scabrous, the apices of the joints somewhat enlarged but not produced; scutellum with a slightly silky yellowish-grey tomentum; elytra rather elongate, cuneate, or with the sides straighter and narrowing more rapidly posteriorly, each with a sunken irregular spot, having a close white tomentum at the bottom but not extending up to the level of the surrounding part; the lateral white stripe does not pass beyond the first abdominal segment; forelegs moderately elongate.

Length 26 lines.

I have only a single specimen of this species, but its metallic gloss, the form of the elytra with the two impressed central spots, and the characters of the antennæ, leave no doubt as to its distinctness from everything else in the collection.

Batocera pulverosa.

B. fusca, griseo-pubescens; elytris totis granulis nitidis tectis.

Hab.—Timor.

Dark brown or black, with a very pale grey or whitish pubescence; head roughly scored in front, the occiput and prothorax finely pubescent, the latter with two bright ochraceous spots; scutellum densely tomentose; elytra entirely covered (except close to the apices) with numerous small crowded glossy-brown granules, the pubescence filling the intervals, two or three patches—one, the most conspicuous, near the middle—with fewer granules, apices sub-sinuate, the sutural angle slightly produced; body beneath with a greenish-grey pubescence, the lateral stripe

[page] 265

gradually becoming obsolete on the abdomen; legs pubescent, pale greyish; antennæ thickened at the apices of the joints in the male, the third to the tenth joints inclusive shortly bispinous.

Length 29 lines.

This, I believe, is the only species, in which the elytra are entirely covered with granules.

Batocera Rosenbergii.

Kaup, Einige Ceramb. der Grossherzogl. Samml. zu Darmstadt, p. —, tab. ii. fig. 4.

B. nigra, nitida, sub-glabra; elytris impresso-fulvo-maculatis vel vittatis.

Hab.—Flores.

Black, shining, sub-glabrous; head coarsely punctured in front, the occiput with a few shallow punctures; prothorax with two fulvous spots; scutellum black, with a large obcordiform sulphur-yellow pubescent spot at the apex; elytra thickly punctured, the punctures filled in with short whitish hairs, with four oblong ochraceous tomentose spots on each, the posterior forming a long stripe, all, especially the last, strongly indenting the elytron, apices obliquely truncate, the sutural angle forming a short spine; body beneath black, with a thin greyish pile; lateral stripe continued to the last abdominal segment; antennæ thickened at the apices of the joints in the male, and shortly bispinous.

Length 26 lines.

§ § Prothorax immaculatus.

Batocera Orpheus.
? Batocera æneo-nigra, J. Thomson, Arcana Naturæ, p. 71.

B. purpureo-nigra, nitida; scutello concolore; elytris vage et confertim punctatis, punctis setuliferis, maculis impressis flavo-tomentosis ornatis, apicibus truncatis, angulo suturali spinoso.

Hab.—Morty, Batchian, Ternate.

Dark purplish-black, shining; head and scape coarsely punctured, the intervals forming irregular ridges, third and fourth joints of the antennæ scabrous, shining, the remainder opake, pale brownish, except at the apices, which are black shining and thickened, each furnished with two short spines, the last only excepted; prothorax with a fringe of bright-yellow hairs at the apex, without

[page] 266

spots of any kind; scutellum glabrous or with a few hairs on the apex; elytra rather elongate glabrous, closely covered with small punctures each having a minute whitish bristle or hair, several rather small impressed spots filled with an ochraceous tomentum, apices truncate, the sutural angle spined; body beneath black, shining, the segments of the abdomen and the various pieces of the sterna bordered with ochraceous hairs, no lateral stripe; legs mostly glabrous, except on the lower edges of the tibiæ.

Length 29 lines.

A noble and very distinct species. Three of my specimens are nearly without pubescence; there is a little along the suture in another, while in the fifth (a female) the pubescence is general, only interrupted by the granules at the base of the elytra, and the punctures over the remainder.

Batocera Gerstaeckerii.

J. Thomson, Syst. Ceramb. p. 551.

B. fusca; elytris fusco-brunneis, nitidis, pube grisescente interrupta tectis; infra subtiliter brunneo-pubescens; apicibus articulorum antennarum (♂) 4—6-spinosis.

Hab.—Sula.

Dark brown; head and prothorax covered with a delicate dark-greyish pile, the latter immaculate; scutellum, base and sides of the elytra fulvous-grey, rest of the elytra with a pale whitish-grey tomentum, interrupted by large irregular glabrous shining blotches, three on each; body beneath chocolate brown, with a short silky pubescence, the white lateral stripe extending to the last abdominal segment; antennæ with the apices of the joints thickened and armed with from four to six or more short spines.

Length 27 lines.

The glabrous glossy patches on the elytra seem to be distinctive of this species.

Batocera Orcus.

B. fusca; elytris pube brevi ochracea vel ochraceo-grisea tectis, maculis circa 6 niveis in medio et postice sitis ornatis; linea laterali prothoracis obsoleta.

Hab.—Ceram.

Dark brown; head and prothorax with a short grey pile, the former rugose in front, the latter immaculate; scutellum with a yellowish-grey tomentum; elytra rather elongate, with a short

[page] 267

ochraceous or greyish-ochraceous pubescence, with about six snowy spots behind the middle and posteriorly, granules at the base small, apices truncate, the sutural angle shortly spinous; body beneath reddish-brown, pubescence thin and greyish, the white lateral line absent from the head and prothorax, and varying according to the light on the abdomen; apices of the joints of the antennæ mostly thickened and shortly bispinous; legs slightly pubescent, that on the lower part of the tibiæ tinged with ferruginous.

Length 33 lines.

The last antennal joint of the female is in my specimen thickened and somewhat falcate. This species is best distinguished from the others in this section of the genus by the white spots on the elytra, and the absence of the lateral stripe from the head and prothorax.

Batocera Ammon.

B. fusca, pube ochraceo-grisea tecta; elytris punctulatis, basi et lateribus exceptis, albido-pubescentibus; linea laterali prothoracis obsoleta.

Hab.—Amboyna.

Allied to the preceding, but there are no white spots on the elytra, which are closely covered with a short whitish pubescence, except at the base and sides, which are ochraceous; numerous small punctures in patches are scattered over their surface, the punctures being very distinct notwithstanding their small size, and in nowise hidden by the pubescence; apices obliquely truncate, the sutural angle rather broad and slightly produced; body beneath and femora luteous, covered with a very regular and delicate fawn-coloured pile, rest of the legs darker; sides of the sterna with a broad white lateral stripe; antennæ incrassated at the apices of the joints and shortly bispinous.

Length 27 lines.

The very distinct punctuation of the elytra, with the uniform pubescence, differentiates this species from every other in my collection.

Batocera Wallacei.

J. Thomson, Arch. Ent. i. 447.

B. nigra, nitida; capite, prothorace supra, elytrisque lateribus et

[page] 268

regione suturali ochraceo-tomentosis; partibus aliis elytrorum maculis numerosis (aliquando fere obsoletis) niveis.

Hab.—Aru, Key, Matabello.

Black, shining; head and disk of the prothorax covered with a short ochraceous tomentum, the latter immaculate; scutellum subscutiform, ochraceous; elytra rugosely punctured, the sutural region and sides with an ochraceous tomentum, the interval glabrous and glossy black, more or less spotted with snowy-white; sometimes the spots are nearly connected throughout, forming an irregular stripe from the base to the apex, or (passing through many stages) they are nearly obsolete, the ochraceous tomentum extending more or less over the whole, or the tomentum is nearly absent altogether; body beneath with a greyish pubescence, the lateral stripe extending from the prothorax to the end of the abdomen; antennæ sometimes nearly three times the length of the body, very scabrous, the apices of the joints thickened, strongly produced on one side, and furnished with two or three stout spines.

Length 22—34 lines.

This is probably the finest species of the genus; it is very variable in size and colour, but in all cases preserves a certain distinctive character not to be mistaken.

Batocera Meleager.

B. fusca, pube fulva tecta; elytris ampliatis, punctis numerosis ferrugineis collocatis, apicibus bispinosis.

Hab.—Bouru.

Brown, with a short close tawny pubescence; head slightly rugose between the eyes; prothorax immaculate; scutellum broad at the base, coarsely and entirely pubescent; elytra large and convex, speckled with numerous rusty shining points, which are more or less crowded together, forming large irregular patches, these points at the base are chiefly composed of the usual granular projections which gradually lose this character and become at the middle little transverse impressions and towards the apex ordinary punctures, but in all cases surrounded by a slight glabrous space except along the sides, where the pubescence is darker and more condensed; apices truncate, each angle ending in a strongly-marked spine; body beneath and legs tawny, no trace of a lateral stripe; antennæ with three or four short spines on each of the thickened apices of the joints.

Length 34 lines.

[page] 269

Batocera læna;.

J. Thomson, Arch. Ent. i. 450.

B. nigra, nitida, pube fulvo-ferruginea tecta; elytris trigonatis, vage punctatis, niveo-maculatis, maculis sæpissime sex vel aliquando fere obsoletis, apicibus truncatis, spina suturali elongata.

Hab.—Aru.

Black, shining, with a yellowish-ferruginous pubescence; head dark tawny, rather rugose in front; prothorax immaculate, strongly transversely sulcate, the disk corrugated; scutellum fulvous; elytra trigonate, granules rather large at the base, gradually passing into punctures at the middle; with impressed spots filled with a snowy-white tomentum, usually three on each, sometimes nearly obsolete, with every variety between; spines truncate, with the sutural angle spined, the external broadly apiculate; body beneath pubescent, fulvous, lateral stripe absent from the head; legs and antennæ thinly pubescent.

Length 20—26 lines.

Resembles B. octomaculata, but the elytra are more trigonate, and, inter alia, the prothorax is immaculate and the head without the white blotch behind the eyes.

Batocera cinnamomea.

B. fusca; capite, prothorace, antennisque basi pallide cinereopubescentibus; scutello albo-tomentoso; elytris ferrugineis, pube cinnamomea dense tectis.

Hab.—Sula.

Dark brown; head, prothorax, and base of the antennæ with a thin ashy pubescence; scutellum densely tomentose, white; elytra reddish-ferruginous, covered with a dense brownish-fulvous or cinnamon-coloured pubescence, rather lighter at the base and furnished with a few granules only, the rest of the elytra impunctate, the apex slightly sinuate, with the sutural angle spined; head impunctate; prothorax without any spots, its centre rather free of irregularities; body beneath with a white silvery pubescence, no distinct lateral stripe; legs with a thin ashy pile.

Length 36 lines.

There is only a female specimen in this collection, but the uniform cinnamon pubescence of the elytra is sufficiently distinctive to keep it apart from any other known to me.

[page] 270

Batocera Attila.

B. fusca, pube cinerea tecta; prothorace fere obsolete sulcato; elytris fusco-plagatis, apicibus truncatis, spina suturali elongata.

Hab.—Sumatra, Java.

Brown, with a short pale ashy pubescence; head smooth, sparsely pubescent; prothorax with the transverse grooves nearly obsolete, two slight impressions in the male marking the usual position of the discal spots; scutellum very obtuse at the apex; elytra with a short pale ashy or whitish pubescence, with several irregular brownish blotches, the apices obliquely truncate, with the sutural angle prolonged into a slender spine; body beneath covered with an uniform fawn-coloured pubescence, the lateral stripe not very distinctly separated from it; legs pubescent, pale ashy; antennæ, except the first and second joints, ferruginous, with a thin ashy pubescence, the apices of the joints, especially the third and fourth, thickened, of a darker colour, and with three or four short spines to the majority of them.

Length 23 lines.

I have not been able to refer this to any of M. Thomson's species.

Batocera Hercules.

Lamia Hercules, Boisduval, Voy. de l'Astrol. p. 495.

B. nigra, nitida, pube brevi albida tecta; elytris validis, impunctatis, basi pauci-granulatis, cæteris pube densa uniformi vestitis.

Hab.—Menado.

Black, shining, covered with a short pearly-white pubescence, particularly close and uniform on the elytra; head between the eyes black and remotely punctured; prothorax impunctate, with a single transverse groove anteriorly, and a transverse undefined impression posteriorly; scutellum white; elytra entirely impunctate, with only a few small granulations at the base, the sides slightly tawny, apices emarginate, the sutural angle with a small spine; body beneath with a thin silvery pile, the white lateral stripe distinct on the head and prothorax; legs and antennæ black, partially pubescent.

Length 40 lines.

The largest and one of the most decided species of the genus. B. Una, White, appears to be very nearly allied.

Batocera leonina.

(?)B. Whitei, Kaup, Einige Ceramb. &c., p.—, tab. iii., fig. 7.

B. ferruginea, fulvo-tomentosa; elytris immaculatis, apicibus bisinuatis et bimucronatis; scapo antennarum haud cicatricoso.

Hab.—Menado.

Derm reddish-ferruginous, covered with a close bright fulvous tomentum; vertex granulated; prothorax immaculate, strongly grooved and corrugated transversely; scutellum transverse; elytra nearly parallel at the sides, (♀) very uniformly covered with tomentum, except the usual granules at the base, the apex of each bisinuate, each angle ending in a well-defined mucro; body beneath and legs with a tawny pubescence, no lateral stripe; antennæ (♀) with scarcely any trace of spines, or in anywise scabrous, the scape without a cicatrix.

Length 27 lines.

My description, like M. Thomson's, is made from a female; but the species is distinguished by the absence of the cicatrix on the scape; the antennæ are about two-thirds longer than the body.

There is in the collection the female of another and apparently distinct species, which is uniformly covered with a thin yellowish-grey pubescence, has the apices of the elytra acutely bispinous, and the antennæ ringed with ashy. It stands under the provisional name of Batocera Claudia in my cabinet.

MEGACRIODES.

Characteres ut in Batocera, sed antennæ muticæ, et elytra postice sensim attenuata, humeris haud spinosis.

The two examples of the type of this genus in my collection, the only ones I am acquainted with, appear to be females, so that the character of the male antennæ remains to be ascertained. In the female, however, they are perfectly mutic, except the minute spines at the apices of some of the joints, and in this respect, as well as in the non-spinous shoulders, the genus differs essentially from Batocera. Mr. Wallace informs me that the spots on this insect when alive were of the richest yellow; one of my specimens still preserves much of this colour, in the other they are pure white. These spots are formed by a singularly dense and matted pubescence.

M. Chevrolat describes the antennæ as 12-jointed, which is erroneous, and the eye as deltiform, which is true only with reference to the small δ, not the capital Δ. The genus is a very natural one, having for its type A. Germari, Hope (Lamia).*

Pedes robusti, æqulaes; femora linearia; tibiæ anticæ vix curvatæ; tarsi dilatati, articulo ultimo mediocri. Prosternum simplex. Mesosternum elevatum, productum.

The principal characters of this genus are the great length of the antennæ in the males, and the linear femora, which, as well as the tibiæ and tarsi, are only slightly variable in length in all the legs. The nearly straight anterior tibiæ and more or less elevated mesosternum are also to be remarked in conjunction with other characters. Two very fine and noble species, but varying very much in size, are comprised in this genus; three others, which I have also referred to it, must for the present remain somewhat doubtful, as I have seen only one example of each, and these are so remarkable that I have given a figure of each.

This fine genus seems to have been misunderstood by authors, and another set referred to it, apparently in ignorance of Serville's type, while the more recently described species have been brought together by M. J. Thomson under the name of Rhamses. The principal characters distinguishing this genus from Monochamus are the long anterior legs of the males, the tibiæ of which are denticulated along the lower edge and armed near the apex with a strong tooth. With regard to the armature of the prothorax,

[page] 277

this is one of those genera in which the lateral tooth seems to be only of specific importance, as it varies from a mere point to a well-marked spine. All the species have the elytra granulate at the base, and the punctures rapidly disappearing towards the apex. The females as usual have fuller and more parallel elytra, with antennæ rarely more than a half as long again as the body, while in the males they are often more than three times as long.

Pelargoderus vittatus.

Serville, op. cit. p. 73.

P. nigrescens, pube subtilissima tectus; elytris vitta pubescente grisea a humeris usque ad apicem.

Hab.—Bouru (and Java).

Blackish, apparently glabrous except the stripes on the elytra, but in reality covered with an extremely short, loose pubescence scarcely distinguishable in colour from the derm; head finely punctured; prothorax slightly corrugated, the lateral tooth reduced to a point; elytra with a few granules on the base, finely and rather distantly punctured, a greyish densely-pubescent stripe extending from the shoulder to the apex; body beneath slightly nitid, and with the legs and antennæ blackish.

Length 14 lines.

The only species with a long grey stripe.

Pelargoderus Arouensis.

Hab.—Aru.

Brown, with a short irregular greyish pubescence indistinctly speckled with fulvous, and behind the middle of each elytron a large oblique dark brown patch, sometimes nearly obsolete; prothorax with a very small tooth on each side; scutellum with a smooth stripe in the middle; each apex of the elytra terminating in an obtuse angle; body beneath and legs speckled as on the upper surface.

The angular apices of the elytra and the nearly obsolete prothoracic tooth are together peculiarly characteristic of this species.

Paragnoma, Blanchard, Voy. au Pôle Sud, iv. 298.

Characteres ut in Pelargodero, sed antennæ haud elongatæ, pedes antici haud elongati, tibiæ muticæ, et mesosternum elevatum.

If these characters apply to the male the genus is perhaps a good one; otherwise the few specimens I have seen, as well as the figure given by M. Blanchard, might very well pass for females of a species of the previous genus. They are particularly like the female of Pelargoderus Arouensis.

[page] 281

Olivier described and figured the type species of this genus many years ago, but until Mr. Wallace sent it to England with two new species, it remained otherwise unknown. The genus is remarkable for the almost perfect flatness of the disk of the elytra, which is suddenly, bent down at the sides at a right angle (less marked however in P. lima), and the sharp ridge thus formed is furnished with a row of short sharply-pointed spines, and at the sides or above with more spines. These species appear to be very rare; I have only seen them in my own collection.

Reddish-brown, closely covered with a scale-like reddish-grey pubescence, and with small partially erect hairs scattered amongst it; head dark brown behind the eyes; prothorax very irregular, with three especially well-marked tubercles, coarsely granulate, the granules dull black, nearly concealed by the pubescence, and with a deep preapical transverse groove; scutellum small, angular, transverse; elytra very flat above, somewhat concave between the base and middle, a few spines on each side of the scutellum forming a kind of crest, and five or six on each side in a line with the discoidal angle, which is furnished with about a dozen of them, another line of spines on the declivity of the side and a few at the shoulder; the discoidal angle, terminating abruptly beyond the middle, is succeeded by a large, somewhat triangular, brown patch, which extends nearly to the apex; body beneath and legs with a close brownish-yellow pubescence, speckled with single hairs of a paler colour scattered amongst it as on the back; the legs, especially the femora, are also marked with numerous short nitid raised lines, in some parts mixed with granules; this mixed kind of pubescence, together with the lines and granules, are also found on the three basal joints of the antennæ, but on the remainder the pubescence is uniformly close, and greyish on a pale testaceous-brown surface.

Length 18 lines; of the antennæ (♂) 33 lines, (♀) 24 lines.

This specimen is a female, and compared with the female of the preceding species it differs in its larger size with much larger elytra proportionally, duller pubescence with less scale-like hairs, the elytra slightly convex along the middle of the flattened part, the discoidal angle less prominent, with fewer spines generally, and the legs and antennæ with fewer and less prominently raised lines, with no admixture of granules, except perhaps a few on the scape.

Length 23 lines; of the antennæ (♀) 32.

Length 14 lines.

PERIAPTODES.

Characteres ut in Protemnemo, sed elytra sub-depressa, haud planata, lateribus rotundatis, inermibus, apicibus solis extus spinosis.

From Monochamus this genus, like Protemnemus, differs in its large eyes, the lower lobe being nearly contiguous to the mouth, and its toothed mesosternum. The three species described below are unfortunately in each case limited to a single specimen, and

[page] 283

are nearly allied, especially the first two. Like Protemnemus they are all furnished above with a greyish scale-like pubescence not quite covering the dark-brown derm beneath. The antennæ of the male are a little longer than those of the female.

Periaptodes lictor. (Pl. XIV. fig. 3.)

Covered above with minute uniformly arranged greyish scales; head rather narrow, the pubescence in front hairlike; prothorax not broader than the head, about equal in length and breadth, exclusive of the long narrow lateral spine which arises from a small base, the disk tolerably equal and without granules; scutellum triangular, covered with a buff tomentum; elytra rather narrow, the base with a large brown cordate blotch, common to both, an oblique brownish band, shading off insensibly behind, beginning near the shoulder and terminating at the suture about the middle, a few minute granules anteriorly, and here and there a pale grey setulose hair, the tooth at the shoulder small and transverse, the spine at the obliquely truncated apex produced; body beneath chesnut-red, with a coarse grey pubescence, the pale setulose hairs more numerous, the legs and three basal joints of the antennæ furnished with pubescence of the same character but more dense, the remainder of the antennæ densely pubescent without the setulose hairs.

Length 12 lines.

Periaptodes testator.

P. griseatus; prothorace haud rugoso, longitudine quam latitudine paulo breviori; elytris vix angustatis, humeris dente obliquo instructis, granulis minutis vage dispersis; scapo haud rugoso.

Hab.—Dorey.

Broader than the last; the prothorax slightly transverse, the scutellum glabrous in the middle, the humeral tooth directed obliquely forwards, the blotch at the base bilobed, and the apex nearly transversely truncate, are the principal characters which differentiate this species from P. lictor.

Length 15 lines.

Periaplodes luctator.

P. griseatus; prothorace sub-transverso, granulato; elytris ampliatis, humeris leviter dentatis, haud granulatis; scapo rugoso.

Hab.—Ceram.

Much larger and stouter than the two preceding, from which it also differs in the following particulars: no setulose hairs on the upper surface, and no granules on the elytra, the prothorax sub-transverse, with several dull black granules on the disk and on the base of the lateral spines, the humeral tooth very small, the blotch at the base transversely reniform, the apex broadly truncate with the outer spine short, and the scape rough from the presence of small, mostly transverse, raised lines.

Length 18 lines.

EPICEDIA.

Epicedia, J. Thomson, Syst. Ceramb. p. 78.

Caput magnum, antice transversum; clypeo in medio emarginato; tuberibus antenniferis crassis, basi sub-approximatis. Oculi mediocres, lobo inferiori obliquo. Antennæ corpori æquales; scapo valido, cylindrico, apice cicatricoso; articulo tertio scapum haud superante; sequentibus gradatim brevioribus. Prothorax inæqualis, lateraliter spinosus. Elytra convexa, robusta, basi sub-cristata, apice rotundata. Pedes mediocres, sub-æquales; femora sub-linearia; tarsi æquales. Prosternum simplex. Mesosternum elevatum, dentatum.

The following species, known in collections as "Leprodera pleuricausta, de Haan," and described under that name by M. Thomson, has been recently separated by that author as the type of this genus, chiefly on account of its shorter antennæ. To this may be added that the head is considerably broader in front and not dilated beneath the eyes, the lower lobe of the eye is smaller and oblique, and the elytra have basal crests. The original examples were from Java.

LEPRODERA.

Leprodera, J. Thomson, Arch. Ent. i. 177.

Caput magnum, infra oculos dilatatum, clypeo late sinuato; tuberibus antenniferis validis. Oculi mediocres, lobo inferiori transverso. Antennæ elongatæ; scapo robusto, sub-cylindrico, apice sæpe producto, valde cicatricoso; articulo tertio scapo longiore, aliquando plumoso; sequentibus gradatim decrescentibus, ultimo (♂) præcedente longiori. Prothorax supra transversim plicatus, utrinque valde spinosus. Elytra ampliata, basi haud cristata, apicibus rotundatis. Pedes elongati, antici (♂) longiores; femora sub-incrassata; tibiæ anticæ intus dentatæ; tarsi sub-æquales. Prosternum simplex vel paulo elevatum. Mesosternum dentatum.

Leprodera plagiata, Thoms., on account of its narrower head and oblique eyes, scarcely enters into this genus as it is here defined, yet these are the characters which principally cut it off from Epicedia; as a secondary character it may be mentioned that the elytra are without basal crests, and therefore on the whole it will better fit into the present genus. All the species have a dark brown or blackish derm, uniformly covered with a greyish or fulvous-grey pubescence, and the brown bands and spots are composed of a very dense cloth-like pubescence without any gloss.

Pubescence sparse, greyish; head remotely punctured in front; prothorax rather narrow, rugosely punctured and impressed, the apical and basal grooves indistinct; scutellum broadly rounded behind; elytra granulate at the base, the punctures beyond gradually disappearing at the middle, a large brown blotch, the greater part of which is behind the middle, and bordered with ochreous on each side; body beneath and legs with a dark ochreous pile; antennæ brown, sparingly pubescent, the scape rather rugose.

Length 15 lines.

A single specimen in my collection, standing under the name of Leprodera vaticina, has a striking resemblance to this species, but is much smaller (9 lines), has a narrower prothorax and the head almost quadrate in front, and the close cloth-like pubescence of the brown elytral patch of the above is replaced by very minute short flattish hairs imperfectly covering the derm. Mr. Wallace however ticketed it and the above with the same number.

HIMANTOCERA.

Imantocera, J. Thomson, Arch. Ent. i. 188; Essai &c., p. 102

Caput exsertum, antice breve, clypeo apice lato; tuberibus antenniferis crassis, divergentibus. Oculi mediocres, normales. Antennæ corpore paulo longiores; scapo obconico, apice valde cicatricoso; articulo tertio scapo multo longiore; quarto tertio breviore, apice lobato-producto et barbato; sequentibus brevibus. Prothorax (♂) latitudine longior, utrinque valde armatus. Elytra breviuscula, ovata, supra sub-planata, basi granulato-cristata, apicibus rotundatis. Pedes validi, antici (♂) longiores; femora incrassata; tibiæ anticæ subarcuatæ, in utroque sexu apice intus dentatæ; tarsi antici dilatati, (♂) piloso-marginatis. Prosternum simplex. Mesosternum dentatum.

M. Thomson in his "Essai" places this genus after Leprodera, but in his "Systema" he puts it with the "Gnomitæ." The species briefly described by Hope (penicillata) was simply referred by him to "Lamia," and seems to have been the type of M. Thomson's genus. One of Mr. Wallace's specimens from Flores has a more uniform colour than the others, all of which appear to have been taken in Borneo and to belong to Olivier's species. Another species, described by myself (Journ. Entom. i. 344), is sufficiently distinguished by, inter alia, the greater comparative length of the third, fourth and fifth joints of the antennæ.

PSAROMAIA.

Caput antice sub-quadratum; clypeo distincto, brevissimo. Oculi magni, profunde emarginati, lobo inferiore rotundato. Antennæ corpore paulo longiores, validæ scapo sub-cylindrico, cicatricoso; articulo tertio longiore; cæteris sensim brevioribus; ultimo apiculato.

Pedes validi; femora sub-incrassata; tibiæ fere rectæ, anticæ breviores; tarsi sub-æquales, paulo dilatati, articulo ultimo elongato. Prosternum simplex. Mesosternum elevatum, antice dentatum.

The large lower lobe of the eye and the comparatively short and thickened antennæ are the most prominent characters of this genus, which does not seem to have any very obvious affinities.

Psaromaia tigrina. (Pl. XIII. fig. 3.)

P. dense pubescens, fulvo-grisea, fusco- et ochraceo-varia; antennis annulatis.

Hab.—Java.

Derm dark brown, covered with a dense tawny-grey pubescence, varied on the elytra with dark brown and speckled posteriorly with ochraceous; head entirely tawny; prothorax slightly depressed on the disk, the centre with a black glabrous spot, and a few small glabrous spots on each side behind, transverse grooves at the apex and base moderately impressed; scutellum triangular; elytra coarsely punctured at the base, punctures smaller and more scattered towards the middle, apices sub-truncate, spots of brown and yellow indefinite, but the former assuming here and there a tessellated appearance; body beneath and legs brownish-tawny; antennæ tawny, the apices of all the joints except the first and second dark brown.

M. Thomson contrasts this genus with Mœcha, belonging according to that author to another "subdivision;" latterly, however, he has recognized its position near Dihammus, from which, as it appears to me, it differs principally in its toothed shoulders.

Anhammus Dalenii.

DIHAMMUS.

Dihammus, J. Thomson, Syst. Ceramb. p. 80.

Caput antice transversum; clypeo indistincto; tuberibus antenniferis validis, sub-erectis. Oculi infra ampliati, distantes. Antennæ (♂) longissimæ; scapo obconico; articulo tertio duplo longiore; 4°, 5°, 6° æqualibus; cæteris gradatim longioribus; (♀) articulis brevioribus. Prothorax transversus, capite haud latior, lateribus in spinam magnam productis. Elytra sub-trigonata, (♀ ovata), apicibus truncatis. Pedes elongati, antici longiores; femora sub-linearia; tibiæ anticæ curvatæ, cæteræ rectæ; tarsi sub-æquales, articulo ultimo mediocri. Pro- et meso-sterna simplicia.

Differs from Nemophas and Anhammus in its short transverse head, conjoined with the larger and squarish form of the lower portion of the eye; from the former genus it is also distinguished by its longer and curved anterior tibiæ in the males, but taking

[page] 291

some of the species of Monochamus into account—M. musivus for example—I scarcely see how Dihammus can be differentiated from it.

Dihammus longicornis.

Monochamus longicornis, J. Thomson, Arch. Ent. i. 444.

D. fuscus, pube obscure grisea sparse tectus; elytris basi albobimaculatis.

Length 22 lines; of the antennæ (♂) 6 inches.

The profemora of the male are remarkable on account of their deeply-grooved inner surface.

Dihammus rarus.

The type of this genus was referred by M. Chevrolat to Monochamus, to which, however, as with many others for which that genus has been the receptacle, it has only a general resemblance, radically differing from it in the elevated and toothed mesosternum.

Blepephæus succinctor.

The Malayan species of this genus have a strong general

[page] 293

resemblance inter se, different from its European and American exponents. I have sought in vain, however, for any character to distinguish them. They appear to vary greatly within the narrow limits of their characters, and it is very difficult to say how far some of these may be permanent. As it is I have here and there "lumped" several individuals under one species that appear to have a primâ facie specific position. They may be divided into sections according to the character of the apices of their elytra; there seems reason, however, to believe that even here there are certain modifications in the same species, so that this character can only be relied on approximatively.

§ Apices of the elytra nearly entire.

Monochamus fistulator.
Lamia fistulator, Germar, Ins. Spec. Nov. p. 478.

M. piceus, omnino griseo-pubescens; scapo apicem versus incrassato; prothorace punctis minutis perpaucis notato, disco regulari; elytris pube æquali tectis, apicibus subtruncatis.

Hab.—Java, Timor, Malacca, Borneo, Bouru, Makian (and India, Ceylon, Queensland).

Pitchy, everywhere covered with an uniform greyish, or yellowish-grey pubescence, the scutellum generally paler; face with a few large scattered punctures, none on the vertex or cheeks; prothorax with a very few minute punctures on each side near the base, the disk nearly equal; scutellum nearly as long as broad, rounded posteriorly, the pubescence coarser; elytra covered with numerous small punctures, apices obliquely sub-truncate, or very nearly rounded in some individuals; antennæ frequently brownishtestaceous, three times the length of the body in the males, the scape short and very considerably thicker towards the apex; intermediate and posterior femora scarcely thickened in the middle.

Length 10—12 lines.

Monochamus defector.

M. rufo-piceus, omnino griseo-pubescens; scapo sub-cylindrico; elytris pube æquali tectis, apicibus rotundatis.

Hab.—Singapore.

Closely resembling M. fistulator, but the scape is more slender and cylindrical and very slightly thicker towards the apex, all the femora are considerably shorter, and the intermediate and posterior are as much incrassated as the anterior.

Length 8 lines.

Monochamus tarsalis.

M. brunneus, dense pubescens, griseatus; scapo apicem versus modice incrassato; scutello transverso; elytris fusco-irroratis, versus suturam sub-seriatim punctatis, apicibus rotundatis; femoribus medio incrassatis, tarsis cinereis.

Pale reddish-brown, having a short close dull-greyish pubescence with numerous small brown blotches on the elytra; head and prothorax sparingly punctured, the vertex impunctate; scutellum transverse, yellowish; elytra towards the suture sub-seriate punctate, apices rounded; body beneath and legs with a thin greyish pile; femora short and thickened in the middle; tibiæ with a pale yellowish tinge; tarsi ashy; antennæ testaceousbrown, with a thin greyish pile, the scape gradually thickened upwards to within a short distance of the apex.

Length 8 lines.

This is one of the most distinct of the species here described, and will be at once recognized by its transverse scutellum; the coloration will probably be variable.

Monochamus productus.

M. piceus, supra pube grisea interrupta tectus; prothorace postice vage punctato, disco sub-bituberculato; elytris maculis glabris dispersis, apicibus oblique truncatis.

Hab.—Bouru.

Pitchy, the pubescence on the elytra dotted with numerous partially glabrous spots; in other respects this species resembles the preceding, but the prothorax has larger and more dispersed punctures and two flattish tubercles on the disk, the scutellum is more triangular, and the apices of the elytra are more decidedly truncate; in the male the antennæ are three times, in the female twice the length of the body.

Length 13 lines.

Hab.—Dorey, Mysol.

Reddish-brown, with a close grey pubescence varying accordin to the light, and having a spotted appearance; face with a few scattered punctures, a few also on the vertex; prothorax with few punctures; elytra narrow in the male, produced at the shoulder, rather remotely punctured, the apices nearly rounded; body beneath and legs with a thinner pubescence; antennæ brownishtestaceous, finely pubescent, the scape elongate, extending to the spine of the prothorax, contracted a little below the apex.

Length 9 lines.

Monochamus litigiosus.

M. piceus, dense griseo-pubescens; scapo spinam prothoracis attingente; elytris fusco-nebulosis, humeris vix productis, apicibus oblique sub-truncatis.

Hab.—Aru.

Pitchy-brown, with a close greyish or ashy opake pile; few punctures on the face, more on the vertex, which has a slight golden hue; prothorax sparingly punctured; elytra rather remotely punctured, scarcely produced at the shoulders, the apices sub-truncate, blotched with brown, especially in the middle; body beneath and legs with a close ochreous-grey pubescence; antennæ testaceous-brown, finely pubescent, the scape elongate, extending to the spine of the prothorax.

Length 9—10 lines.

The longer scape distinguishes this species and the preceding from their congeners. Between themselves they are at once diffe-

rentiated by the blotched and opake pubescence of the one contrasted with the varying subnitid pubescence of the other.

Monochamus feralis.

M. fuscus, opacus, pube sparsa tectus; scapo brevi, incrassato; elytris sub-griseatis, basi, fascia postmediana, apiceque fuscis, apicibus fere transversim sub-truncatis.

Hab.—Flores.

Brown, rather thinly covered with an opake dull greyish or brownish pubescence; head and prothorax with few punctures; scutellum paler; elytra remotely punctured, apices nearly transversely sub-truncate, dull brownish-grey, the base, the band nearly behind the middle, and the apical portion dull brown, these colours obscurely limited, the grey slightly spotting the brown and the brown more decidedly blotching the grey; body beneath and legs with a pale-ochreous pubescence, the tibiæ somewhat hairy; antennæ brownish, the scape thick, scarcely extending beyond the apex of the prothorax.

Length 9 lines.

Monochamus tincturatus.

M. fuscus, breviter pubescens, rufo-fuscus, griseo-irroratus; scapo apicem versus incrassato; elytris angustis (♂), apicibus oblique sub-truncatis.

Hab.—Waigiou.

Brown, with a short dark reddish-brown pubescence, blotched or spotted with greyish; vertex impunctate; face and prothorax with very few punctures; scutellum brownish; elytra narrow in the male, finely punctured, apices obliquely sub-truncate; body beneath and legs with a very delicate greyish pile, varying according to the light; antennæ pale greyish, the scape short and obconical.

Length 9—10 lines.

In one specimen the basal half of the elytra is almost entirely dark reddish-brown, in another the shoulders and portions of the shoulders are grey, and elsewhere the grey has a more spotted appearance.

§ § Apices of the elytra shortly toothed externally.

Monochamus magneticus.

M. pube sericea tectus; elytris argenteo-mutantibus, apicibus sub-oblique truncatis, angulo exteriore vix producto.

Hab.—Ceram, Aru?

[page] 297

Covered with a short silky pubescence, varying according to the light; head and prothorax yellowish-grey, with few punctures, none on the vertex; the prothorax with a slightly elevated median line; scutellum semicircular; elytra irregularly punctured, the pubescence greyish, with irregular patches, brown or silvery according to the light, the apices slightly obliquely truncate, the external angle forming a very short but distinct tooth; body beneath and legs with a close yellowish-grey pile; antennæ three or four times as long as the body, reddish-brown with a short greyish pubescence, the scape moderately thickened upwards.

Length 10 lines.

A specimen from Aru, which may be the female, differs in having a much less silky pubescence, and the apices of the elytra show no vestige of a tooth. I have seen a similar specimen in the British Museum, ticketed "M. holotephrus, Bois.," but that author describes the prothorax as having "plusieurs rides transverses," and the description is in other respects dubious.

Monochamus convexus.

M. piceus, pube opaca grisea tectus; elytris convexiusculis, leviter punctatis, apicibus sub-sinuatis, angulis suturali et exteriore paulo productis.

Hab.—Kaioa.

Pitchy-brown, with an opake grey pubescence; head rather broad in front, the eyes less approximate, the vertex impunctate; prothorax very short and transverse, a slight prominence on the centre, a few punctures behind it almost obsolete; scutellum nearly semicircular; elytra rather more convex than usual, finely punctured, the apices somewhat broadly sinuate, each angle a little produced; body beneath and legs pubescent, slightly silky, greyish; antennæ pubescent, greyish, nearly twice as long as the body (♀), the scape much thicker towards the apex.

Length 12 lines.

Monochamus viator.

M. rufo-brunneus, pube griseo-mutante tectus; elytris apicibus oblique truncatis, angulo exteriore obtuse producto; antennis pedibusque testaceis.

Hab.—Matabello.

Light reddish-brown, with a thin short greyish pubescence

[page] 298

varying according to the light; head and prothorax with very few punctures, the anterior transverse groove of the latter obsolete in the middle; scutellum semicircular; elytra with greyish patches in consequence of a more condensed pubescence, but varying with the light, apices obliquely truncate, the outer angle obtuse; body beneath brown, legs and antennæ testaceous, all with a fine greyish pubescence, scape gradually thickened as far as the middle, cylindrical beyond.

Length 6 lines.

M. fuscescens, pube sericea brevi tectus; elytris griseo-mutantibus, apicibus truncatis, angulo exteriore in spinam longam producto; antennis annulatis.

Hab.—Dorey, Menado, Kaioa.

Brownish, covered with a short silky pubescence; head and prothorax with few punctures, the latter with a slightly raised central line; scutellum semicircular; elytra with small patches, greyish or brownish according to the light, and having a slightly oblique direction downwards towards the suture, the apices truncate, the outer angle produced into a spine, the length of which is nearly equal to the breadth of the truncature; body beneath and legs reddish-testaceous with a greyish pile; antennæ three times as long as the body, testaceous, pubescent, tips and bases of the joints dark brown; scape moderately thickened upwards.

Length 8 lines.

A minute analysis of the three specimens I have here brought together as one species would necessitate a separate description of each; and this remark might be applied to other species of this very variable genus.

Monochamus anxius.

M. rufo-testaceus, pube grisea nebulosa brevissima tectus; elytris leviter punctatis, postice fere obsoletis, apicibus truncatis, intus sinuatis, in spinam longam externe productis; antennis sub-annulatis.

Hab.—Batchian, Bouru?, Saylee?, Gilolo?

Perhaps only a variety of M. captiosus, but different in colour, in pubescence—which is thinner, the varying grey tints forming

[page] 299

larger masses—and in the apices of the elytra, which are less truncate, or more sinuate, internally. The Bouru specimen has stronger punctures on the prothorax and they are distributed in a different way; the Saylee and Gilolo examples have a more opake pubescence, and the former is scarcely more than half the length of the type; there are also other differences.

Length 10 lines; the Saylee specimen 6 lines.

Monochamus argutus.

(?) Lamia fasciata, Montrouzier, Faun. de Woodlark, p. 63.

M. fuscescens, pube sericea brevi tectus; elytris griseonebulosis, extus et basin versus sat dense punctatis, apicibus truncatis, angulo exteriore producto.

Hab.—Ternate, Aru, Bouru.

Broader than M. captiosus, which it otherwise much resembles. Brownish, covered with a silky silvery-grey pubescence, more uniform on the prothorax, the lights on the elytra indistinctly interrupted by two oblique darker patches, punctures rather coarse and crowded externally towards the base (but this character is much less evident in the Aru specimen), apices truncate or sub-truncate, the outer angle more or less spinous; body beneath and legs with a thin greyish pile; antennæ testaceous, tips and bases of the joints brownish.

Length 9 lines.

Monochamus solatus.

M. validus, griseo-pubescens; prothorace fere impunctato; elytris fusco-irroratis, apicibus sat late truncatis, angulo exteriore producto.

Hab.—Makian, Batchian, (♀ Gilolo?).

Robust, brown, with a greyish pubescence; prothorax nearly impunctate, the disk with three rather prominent tubercles; scutellum rounded behind; elytra broad at the base, narrowing rather rapidly posteriorly, finely punctured, the apex rather broadly truncate, the external angle acute; body beneath and legs black, with a thin yellowish-grey pile; antennæ dark brown, pubescent, greyish, the intermediate joints with small glabrous spots.

Length 13 lines.

The female specimen from Gilolo has a nearly smooth prothorax and is without any glabrous spots on the antennæ. The Batchian example has longer spines to the apices of its elytra.

Monochamus uræus.

M. rufo-testaceus, pube subtile tectus; capitis vertice argenteo; elytris vage punctatis, apicibus oblique punctatis, extus spinoso-productis.

Hab.—Mysol, Sula.

Reddish-testaceous, with a peculiarly delicate greyish pubescence, which scarcely lends any effect to the general colour, except that it shows a somewhat silvery gloss in certain lights; head yellowish in front, silvery-white on the vertex; prothorax with few punctures; elytra with the punctures rather dispersed, apices sub-truncate, with a well-marked spine at the outer angle; body beneath and legs reddish-brown, thinly pubescent; antennæ testaceous, the tips of the intermediate joints brownish.

Length 6 lines.

There are two more very distinct species in the collection which might have entered into the old genus Monochamus, but I forbear to do more than mention their existence; one from Sarawak is much worn, the other from Singapore is only a female, and neither appears to fit into any of the genera here mentioned.

EPEPEOTES.

I have separated this genus from Monochamus, which it otherwise much resembles, on account of the strongly produced and toothed mesosternum, and the large eyes which are much nearer together than in the former genus. The type is an old and extensively distributed species, (Lamia lusca, Fab.)

Mr. Newman's type has three dark stripes on the prothorax.

DIOCHARES.

Caput antice transversum, tuberibus antenniferis validis, basi remotis. Mandibulœ validæ. Oculi magni, lobo inferiore rotundato.

Mesosternum dentatum.

This genus is separated from Monochamus on account of its widely-placed antennary tubers, large eyes, and toothed mesosternum; and these characters, taken together, separate it also from all other genera of Lamiinæ proposed in this work. The type was long ago described by Olivier, but does not appear to have been recognized by subsequent authors, except Fabricius, who gave it another name; it is very variable in colour. D. lugubris and D. impluviatus are described from single specimens, and it is possible that similar variations may occur in them. Monochamus ambigenus, Chev., also belongs to this genus.

versim varia; apicibus elytrorum angulo externo in dentem producto.

Hab.—Batchian, Kaioa, Ceram, Goram, Ternate, Makian, Gilolo, (and Manilla.)

Black, nitid, varied with white, grey, or ashy, depending on a very close-set pubescence, generally well limited, while the black portions have a very short and scattered or almost obsolete pubescence; on the vertex are three white lines which meet in front, and these are continuous with three corresponding lines on the prothorax; scutellum semicircular, black or white, or with a white border only; elytra with irregular scattered punctures, the shoulders granulate, the white parts varying in extent or becoming grey, but always having a transverse direction; the normal style is perhaps based on two irregular white bands, thus dividing the black into three portions, the bands nearly disappearing or gradually extending so as to reduce the black to a few spots in many examples; body beneath with a thin pubescence, grey or ashy, the abdominal segments with one or two lightcoloured spots on each side, which are sometimes obsolete; legs with a grey or ashy pubescence; antennæ blackish, in the males about half as long again as the body, sometimes ringed with ashy.

Length 8—14 lines.

Diochares lugubris.

D. fuscus, opacus, pube grisea variegatus; apicibus elytrorum angulis haud productis.

Hab.—Tondano.

Dark brown, opake, finely and closely pubescent, varied with a clear grey depending on a stouter pubescence; face greyish, line round the eyes, three lines on the vertex meeting in front and continuous with three corresponding lines on the prothorax, yellowish-grey; scutellum with a greyish spot in the middle; elytra with scattered punctures almost hidden by the pubescence, a few granules on the shoulders, base dark brown with a few greyish spots, followed by a greyish sub-median band extending forwards at the sides, spotted with brown, then a large brown patch with a few greyish spots, and lastly greyish again with brown spots, apices sub-truncate or slightly sinuate, neither of the angles produced; body beneath and legs with a close ochreous-grey pubescence; antennæ brown.

Length 10 lines.

Diochares impluviatus.

D. niger, pube alba variegatus; elytris angustatis, apicibus sub-truncatis.

Hab.—Tondano.

Black, varied with a coarser white pubescence; head whitish in front, the lines round the eyes and on the vertex and prothorax precisely as in the preceding; scutellum white in the middle; elytra narrow, granulate on the shoulders, finely punctured, white, speckled with black, the black predominating along the suture at the base and middle and forming irregular patches, the apices sub-truncate; body beneath and legs with a pale ashy pubescence; claw-joint not longer than the two preceding joints together; antennœ blackish, twice as long as the body.

Length 6 lines.

TRYSIMIA.

Caput antice sub-quadratum, clypeo truncato; tuberibus antenniferis validis. Oculi mediocres, lobo inferiori rotundato. Antennœ longissimæ; scapo obconico, valde cicatricoso; articulo tertio scapo duplo longiore; quarto breviore; cæteris æqualibus, ultimo excepto. Prothorax longitudine haud latior, lateribus sub-rotundatis, tuberculo minuto instructis. Elytra sub-trigonata, apicibus rotundatis. Pedes elongati, inæquales, antici longiores; femora incrassata; tarsi æquales. Mesosternum haud dentatum.

This genus differs from Monochamus only in its sub-quadrate face, and the small lateral tubercle of the prothorax replacing the stout tooth of the latter. It comprises two very distinct but cognate species.

Trysimia geminata. (Pl. XIV. fig. 2.)

T. fusca, leviter griseo-pubescens; elytris albo-irroratis, præcipue maculis quatuor majoribus.

Hab.—Bouru, Ceram, Amboyna.

Dark brown, with a thin uniform greyish pubescence; head impunctate, a black glabrous mark at the angle of the mouth below the eye; prothorax impunctate, an indefinite blackish spot in the centre; scutellum rounded posteriorly; elytra granulate at the base, the granules gradually passing into punctures, which disappear near the apex, several small greyish spots composed of a

very dense tomentum, but especially two large spots, one before the other behind the middle, each of these spots formed by the junction, or very nearly the junction of two, but variable even in the same specimen; the example from Ceram has the spots pure white; body beneath and legs with a close fulvous-grey pile; antennæ brownish, minutely pubescent.

Length 11 lines, of the antennœ (♂) 33 lines.

Trysimia rugicollis.

T. fusca, leviter griseo-pubescens; prothorace transversim lineato; elytris albo-irroratis.

Hab.—Macassar.

Brown, with a short sparse greyish pile; frontal impressed line terminating between the eyes in an interrupted transverse ridge, an oblique glabrous black mark at the angles of the mouth; prothorax transverse, two apical and two basal grooves, between the two series numerous transverse contorted lines, the centre and a spot on each side dark brown; scutellum rounded; elytra with a few granules on the shoulders, thickly punctured at the base, the punctures disappearing near the apex, speckled with small densely tomentose white spots; body, legs and antennæ yellowish-brown, finely pubescent.

Length 8 lines, of the antennæ (♀) 11 lines.

NEPHELOTUS.

Caput antice quadratum; clypeo truncato; tuberibus antenniferis validis, basi separatis. Mandibulœ breves. Oculi mediocres, lobo inferiore verticali vel angustato. Antennœ elongatæ; scapo sub-cylindrico; articulo tertio scapo longiore; quarto breviore; sequentibus sub-æqualibus. Prothorax regularis, cylindricus, lateraliter dente minuto instructus. Elytra sub-angustata, humeris in dentem productis, apicibus rotundatis. Pedes mediocres, in utroque sexu æquales; femora modice incrassata; tarsi articulo ultimo elongato. Prosternum simplex. Mesosternum haud dentatum.

The prothoracic spine in this genus is reduced to a mere point; the legs are equal in both sexes; and the claw-joint is of large size, but this seems to be a character of less importance among these genera than it is in other groups. In other respects the genus is near Monochamus, except that the head is more quadrate in front.

Nephelotus licheneus. (Pl. XIV. fig. 1.)

N. piceus, pube squamiformi grisea vel ochreo-grisea tectus; elytris oblique seriatim punctatis, fusco-irroratis, plaga magna albida ante medium sita.

Hab.—Sarawak.

Pitchy, covered with a small grey or ochreous-grey scale-like pubescence; head with a few large black punctures in front, none on the vertex or prothorax, the latter smooth but with wellmarked apical and basal grooves; scutellum rounded behind; elytra granulate at the base, obliquely seriate-punctate, the punctures small, some of them larger than the rest and partially glabrous at the edges, giving a speckled appearance to the elytra, a large whitish patch lying directly before the middle and extending nearly to the base; body beneath and legs with a clear ochreous pubescence; antennæ brownish-testaceous, nearly glabrous, the first two joints with an ochreous pubescence.

Length 10 lines.

ORSIDIS.

Caput antice breve, convexum; clypeo truncato; tuberibus antenniferis sub-remotis. Oculi magni, lobo inferiore rotundato. Antennœ elongatæ; scapo sub-cylindrico, apice rotundato, cicatrice haud distincta; articulo tertio scapo longiore; quarto et quinto sensim brevioribus; sequentibus æqualibus, ultimo excepto. Prothorax sub-cylindricus, lateraliter valde spinosus. Elytra angustata, humeris haud productis, apicibus rotundatis. Pedes mediocres, æquales; femora incrassata; tibiœ anticæ breviusculæ, arcuatæ; tarsi articulo ultimo breviusculo. Mesosternum haud dentatum.

The cicatrix on the scape is in this genus nearly obsolete, a slight line only representing it. The legs are nearly equal in length and the claw-joint in all the species before me is unusually short. There are no granules on the elytra.

Orsidis oppositus. (Pl. XIV. fig. 4.)

Hab.—Sarawak.

Dark brown, with a greyish or ashy pubescence, the scutellum with a thick ochreous pubescence; head and prothorax with small distant punctures; elytra seriate-punctate, the punctures gradually disappearing towards the apex; body beneath and legs with a very delicate pale ashy or greyish pubescence; antennæ dark brown, the bases of all the joints except the first white or paler at the base.

Length 4—5 lines.

There are two specimens ticketed with the same number by Mr. Wallace, one much narrower than the other, with a pale ashy pile, and antennæ indistinctly ringed; the second is much darker, with shorter antennæ ringed with pure white.

Reddish-brown, entirely covered with a fawn-coloured pubescence, which is a little finer on the body beneath and legs;

[page] 310

head and prothorax impunctate; scutellum with a yellowish pubescence; elytra irregularly punctured at the base, the punctures assuming a more linear arrangement near the suture, the apex of each elytron drawn out into a small angle; antennæ pale reddish-testaceous, the apices of the joints brown.

Hab.—Macassar.

Dark brown, with a very delicate close ashy pubescence; head and prothorax impunctate, the latter less transverse than in O. incomptus, and having a very slight longitudinal median ridge; scutellum greyish; elytra rather narrow, subseriate-punctate, the apices sub-angular; more sparingly pubescent beneath and on the legs; anterior femora very thick; antennæ reddish-brown, pubescent.

Length 6 lines.

This species did not occur in Mr. Wallace's own collection; my original specimen serves for the above description, and this, as mentioned loc. cit., has the eighth joint of its antennæ remarkably thickened; whether this is its normal character seems doubtful.

PSECTROCERA.

Psectrocera, Pascoe, Journ. of Ent. i. 345.

Caput exsertum, antice sub-transversum, convexum; tuberibus antenniferis valde divergentibus. Oculi mediocres, normales. Antennœ corpore longiores; scapo pyriforme, apice cicatricoso; articulo tertio scapo duplo longiori; cæteris gradatim brevioribus, tribus ultimis æqualibus exceptis; tertio, quarto et quinto apice plumosis. Palpi mediocres. Prothorax elongatus, cylindricus, inermis. Elytra breviuscula, ovata, supra sub-depressa, basi granulato-cristata, apicibus rotundatis. Pedes mediocres, antici (♂) multo longiores; femora incrassata; tibiœ anticæ sub-curvatæ, apice intus dentatæ, intermediæ emarginatæ; tarsi ut in Himantocera. Prosternum simplex. Mesosternum sub-dentatum.

Nearly allied to Gnoma, but differentiated by its cylindrical prothorax, pyriform scape, and plumose antennæ. Between this

[page] 311

genus and the preceding there is a very considerable break, but this cannot be avoided in a linear arrangement. The only described species of Psectrocera has been long known as the scopulicornis of Dejean's Catalogue, and was originally from Java.

Pedes elongati, antici præsertim in ♂ longiores, postici breviores; femora in medio modice vel vix incrassata; tibiæ anticæ sub-arcuatæ, apice intus dentatæ; tarsi antici (♂) frequenter longiusculi, dilatati, piloso-marginati, postici minores. Prosternum angustatum, simplex. Mesosternum dentatum.

The species of this very natural genus are very difficult to dis-

[page] 312

criminate so far as regards the males, and the females, as it appears to me, are absolutely undistinguishable. Scarcely any of the characters appear to be permanent, and all the specimens, so far as I have noticed them, may be divided into two categories, each of which might be conveniently considered to represent one very variable species—Gnoma giraffa, Schreib., representing the long-necked black category, and Gnoma sticticollis, J. Thoms., the shorter-necked brownish and spotted category. It will be very difficult to ascertain what are the really permanent species with our present data. The following descriptions apply exclusively to the males; the females have always shorter necks, legs and antennæ, and the elytra broader and more parallel, and often more varied with white than the males.

G. nigra, nitida; elytris basi granulato-punctatis, punctis apicem versus gradatim obsoletis.

Hab.—Ceram, Amboyna, Matabello.

Glossy-black, the legs with a blueish, the elytra with a greenish tinge; head and prothorax together as long as the elytra; the former with small distant punctures; prothorax finely corrugated; scutellum rounded, covered with densely-set white hairs; elytra moderately broad at the base, thickly set with small granules, which gradually pass into punctures but become smaller and more dispersed towards the apex, the latter very slightly pubescent; body beneath glossy-black; antennæ more than twice as long as the body, first three joints very rugose. The female is stouter and often spotted with white.

Glossy-black, stripe on the middle of the prothorax, a spot at the base of the elytra near the shoulder, the suture, and often

[page] 313

a few specks on the sides, white; sculpture of the prothorax and punctures on the elytra as in G. giraffa; body beneath black, sterna, abdomen and legs with a very delicate greyish-white pubescence; episterna and epimera of the mesothorax and abdominal segments at the sides white. The example from Ternate is more pubescent, and therefore less glossy than the others. The female varies considerably in the amount and disposition of the white portion. G. albo-vittata, Thoms., is probably one of them.

Gnoma propinqua.

G. nigra, nitida; vitta mediana prothoracis, suturaque albis; elytris breviusculis, trigonatis.

Hab.—Makian.

Resembles the preceding except in the white pubescence being confined to a central stripe along the prothorax and elytra—a point probably of little importance—but the elytra are much shorter and much broader at the base, and are very decidedly trigonate. There is but a single specimen in the collection; but (with the proviso mentioned above) I have not the slightest hesitation in separating it from the preceding.

Broader and more robust than any of the preceding, without any sutural stripe on the elytra, which are more or less speckled, the median stripe on the prothorax variable, sometimes nearly obsolete; one large central white spot on each elytron, a smaller one near the apex; the epimera and episterna of the mesothorax and sometimes the borders of the abdominal segments white.

Glossy-black, distinguished from all the other species by the smoothness and impunctuation of the elytra except at the base; in colour some specimens are entirely black, always excepting the scutellum, others are as described by M. Thomson.

Length 6—10 lines.

Possibly several species are here united, but I must confess that I am unable to separate them by any characters that can be relied upon as permanent. I cannot distinguish M. Thomson's Gnoma sticticollis, Arch. Ent. i. 297, by his description, from this or either of the two preceding species.

MECOTAGUS.

Mecotagus, Pascoe, Proc. Zool. Soc. 1866, p. 252.

Prothorax elongatus, sub-cylindricus, lateribus haud vel vix antice incurvatis. Elytra breviuscula, ovata, apicibus emarginatis. Pedes elongati, antici longiores; femora linearia; tibiœ anticæ sub-arcuatæ, apice inermes; tarsi articulo basali sub-elongato. Prosternum simplex. Mesosternum elevatum, productum.

Cerambyx tigrinus, Oliv., is the type of this genus, a congener of which has been erroneously referred by Mr. White to Pelargoderus, Serv. It is allied to Gnoma, from which it differs in the form of the prothorax, the linear femora, the longer basal joint of the tarsi, and other characters. The species referred to by Mr. White under the name of "P. tessellatus, Guér.," does not appear to be described; the following has a very distinct style of pubescence from the (two?) species previously known.

Pedes inæquales, antici longiores, præsertim in maribus, postici breviusculi; femora modice incrassata; tarsi postici minores. Pro- et meso-sterna elongata, declivia.

Olenecamptus is a well-marked genus, at once distinguished by its short rough scape without a cicatrix, in conjunction with its short posterior legs. A remarkable and probably dimorphous variety has been separated from O. bilobus by M. Chevrolat, on account of the inner edge of the fore tibiæ being minutely serrated, under the name of O. serratus. I have similar examples from Timor and Flores. The inner edge of the antennœ is sometimes serrated in the same way. This species has a very wide range, being found all over India, Ceylon, Java, &c., and has been also reported from Australia.

Caput exsertum, antice breve, transversum, clypeo apice late sinuato; tuberibus antenniferis crassis, basi sub-approximatis. Oculi mediocres, profunde divisi, lobo superiore valde angustato. Palpi graciles. Antennœ elongatæ, setaceæ; scapo rugoso, sub-pyriformi, prothoracem haud attingente, apice haud cicatricoso; articulo secundo brevissimo; tertio scapo quadruplo longiore; cæteris tertio brevioribus et sub-æqualibus, ultimo excepto. Prothorax in utroque sexu cylindricus, capite haud latior. Elytra sub-elongata, parallela, apicibus acuminatis vel rotundatis. Pedes graciles, elongati, præsertim postici; femora fusiformia; tibiæ fere lineares; tarsi breves, æquales. Pro- et meso-sterna declivia.

An elegant genus, only known before Mr. Wallace's researches by a single species, and at once distinguished from any of the preceding, except Olenecamptus, by the non-existence of a cicatrix on the scape, and from that it is well separated by the great length of the posterior legs, which, except in one species, are longer than the anterior, an unusual character in the sub-family. The species vary greatly in colour, but are all finely pubescent.

The only representative of this remarkable genus, which in

[page] 321

outline resembles a Phalangium, has been long known, and is rather local and exceptional in its habitat, but wherever it occurs it seems to appear in large numbers. The female has shorter legs and antennæ than the male, but otherwise scarcely differs. It must have been this sex that was described by Fabricius from a specimen in the collection of Bosc. As I am not aware of the existence of any figure of the species, I have given one of the male.

G. albo-pubescens, maculis brunneis vel fuscis varia.

Hab.—Java, Malacca, Lombok, (and Siam).

Closely covered with a pure white, or sometimes dingy-white, somewhat coarse pubescence, with intervals of reddish-brown or dark-brown spots of the derm clothed only with a very delicate pubescence; head with two spots on the forehead and two on the vertex; prothorax with three spots on the disk, and two on each side; spots on the elytra more or less united so as to form four irregular bands, or the two posterior bands by their union forming only one; body beneath, legs and antennæ black, with a short delicate pubescence.

Length 8 lines; anterior legs (♂) 24 lines; antennæ (♂) about 25 lines.

ONOCEPHALINÆ.

This sub-family exactly accords with M. J. Thomson's 14th "groupe," as defined and limited by him in the "Essai" (p. 120), so far as its members were at that time known. It was there composed of the four genera Gryllica, Pachypeza, Ischioloncha and Onocephala. In the more recent "Systema" he makes it a "division" of his "groupe" Hippopsitæ, retaining of the above only Onocephala, and adding two new forms—Atossa and Apechthes.

The form and position of the head is the most salient character of the Onocephalinæ; in the typical genus Onocephala, it is rather large, produced and contracted above, so that the antennary tubers are nearly or quite contiguous, dilated and prolonged below the eyes which are small in proportion, and is bent inwards so that the face is more or less in a line with the under surface. The antennæ vary in length, but they are generally either pilose or fimbriated beneath, with the scape almost perfectly cylindrical and without a cicatrix; the legs are either of moderate length, or so short as not to extend beyond the extremity of the

body; the tarsi are always short, with the claw-joint usually of remarkable size.

This sub-family appears to be confined to tropical America and to the Malayan region; in Mr. Wallace's collection it is represented by a single individual, which, I am sorry to say, is in a very poor condition, and it is only because of its importance as the sole representative of its sub-family that I have noticed it. Besides several genera described by M. J. Thomson, but unknown to me (except Atossa), and some of which may probably prove to belong to this sub-family, I have two or three unpublished forms which I include in it; I think also that Mr. Newman's genus Epaphra from Manilla may also be referred to it, although of a somewhat aberrant character.

PHELIPARA.

Caput fronte modice productum, infra oculos vix dilatatum, tuberibus antenniferis validis, contiguis, fere erectis. Oculi tenue granulati, mediocres, lobis superioribus parvis, approximatis. Antennœ fimbriatæ; scapo elongato, cylindrico. Prothorax capite paulo latior, sub-cylindricus. Elytra elongata, basi prothorace multo latiora, postice sensim attenuata, apicibus sinuatis, angulo externo dentato. Pedes breves; femora incrassata; protibiæ curvatæ; tarsi æquales, articulo ultimo valde elongato. Coxæ anticæ globosæ, divergentes, haud approximatæ. Pro- et meso-sterna mutica.

The antennœ of this unique example are broken off at the third joint; in other respects it appears to have most of the characters of Pachypeza, but with larger claw-joints, the anterior coxæ more globose, and the apices of the elytra sinuate.

Phelipara marmorata.

P. fuscescens, pube sparsa tecta; elytris basi albo-marmoratis, postice lineis longitudinalibus fulvis.

Hab.—Sarawak.

Pale brownish, covered with a thin mostly greyish pile; eyes margined with yellow hairs, two lines of yellow hairs also on the cheeks below the eyes; prothorax transversely corrugated, the anterior and posterior borders and five stripes between the apical and basal grooves composed of yellow hairs; elytra finely punc-

[page] 323

tured, the base marbled with white reticulated veins, posteriorly a few narrow yellowish indefinite stripes; body beneath and legs pale-brownish, with a loose greyish tomentum, the epimera of the metathorax densely clothed with white hairs.

Length 11 lines.

HIPPOPSINÆ.

No other sub-family of Longicorns presents a head so peculiar in its form and direction as the more typical members of the Hippopsinœ. In these it is of a conical shape, and, as a cone, porrect; the upper line forms the vertex and the lower the face, the apex bears the antennæ, which are almost or quite contiguous at the base, and the eyes are most abnormally placed at some distance from the insertion of the antennæ. But, as usual, these peculiarities shade off in the different genera, so that at last we are led rather by general resemblance than by any definite characters to decide on their affinites.

The Hippopsinœ lie directly between the Onocephalinæ and Saperdinæ; the former sub-family shows the same tendency to the horizontal position of the head, although in a less degree, but always has the eyes in the normal position, a more robust form, and the pro- and meso-sterna shorter, so that the anterior and intermediate coxæ are more or less approximate, while in the Hippopsinœ these conditions are reversed. The relations of the Hippopsinœ with the Saperdinœ will be noticed further on.

The members of this sub-family are found all over the world, except Europe,* but are apparently not very numerous either as to species or individuals. From Australia, indeed, we have as yet only a single exponent of the group, Essisus, recently described by me in Proc. Linn. Soc., Zool., ix. 90. The number of species in Mr. Wallace's collection is only five, distributed into three genera.

* M. J. Thomson has, in his Systema &c. (p. 97), referred Calamobius, Guérin, to Hippopsis, an error which I have already noticed in the Society's Proceedings, 1865, p. 126, but which, having been adopted by M. Léon Fairmaire in the "Genera des Coléoptères d'Europe," may probably lead to the name Hippopsis being found in some future European catalogue.

APOPHRENA.

Caput sub-conicum, tuberibus antenniferis apice sitis, contiguis, crectis. Oculi magni, antennarum basi vix contigui, fortiter emarginati, lobo inferiore prominulo, rotundato. Antennæ filiformes; scapo cylindrico, basin elytrorum attingente; articulo tertio paulo breviore; cæteris fere sub-æqualibus. Prothorax cylindricus. Elytra prothorace latiora, apicibus spinosis. Pedes brevissimi, tarsi angustati, articulo ultimo elongato. Pro- et meso-sterna declivia. Corpus gracile.

This genus differs from Hippopsis only in the contiguity and direction of the antennary tubers, and in the eyes being situated at a little distance from the base of the antennæ, a modification which we find still further carried out in Tetraglenes and other genera. Of the three species described below it might perhaps have been more natural to have made A. montana the type of a separate genus, as it has peculiar wedge-shaped elytra and longer legs.

Apophrena filifera. (Pl. XV. fig. 7.)

A. fusca; elytris parallelis, apicibus spinoso-acuminatis.

Hab.—Sarawak.

Brown, with a minute greyish pubescence; head and prothorax sparingly punctured, the former with a median and two lateral yellowish lines, the lateral extended also along the sides of the prothorax; scutellum scutiform, covered with a yellowish silky pile; elytra parallel, rather coarsely punctured, a few indistinct stripes of yellowish posteriorly, each apex produced into a well-marked spine; antennæ about four times as long as the body, entirely brown; body beneath and legs brown, the posterior legs not extending beyond the elytra.

seriate-punctate, the punctures here and there divided by irregular raised lines clothed with greyish hairs, the apices rather deeply sinuate, the outer angle especially produced; antennæ nearly four times as long as the body, the third, fourth and fifth joints pale testaceous at the base; beneath and legs with a thin grey pubescence.

Length 4 lines.

Apophrena montana.

A. castanea, glabra, nitida; elytris basi dilatatis, postice attenuatis, apicibus oblique truncatis, angulo externo producto.

TETRAGLENES.

Tetraglenes, Newman, Entom. i. 300.

Caput conicum, tuberibus antenniferis apice sitis. Oculi quatuor, parvi, laterales, a basi antennarum distantes. Os minutum, propectori contiguum. Antennœ lineares, fimbriatæ, corpore paulo longiores; scapo cylindrico, elongato; articulo quarto tertio longiore; cæteris gradatim decrescentibus. Prothorax elongatus, sub-cylindricus. Elytra prothorace vix latiora, sub-parallela, elongata, postice dehiscentia. Pedes brevissimi; femora incrassata; protibiœ curvatæ; tarsi æquales. Pro- et meso-sterna planata, elongata. Corpus sub-lineare.

Mr. Newman says that this is the only insect he has seen "posessing four distinct and widely separated eyes," * * * "each eye being apparently independent of the other three." This is not strictly correct, as a fine line may be distinctly traced evidently connecting the two lobes. That these lobes should be placed at

[page] 326

a considerable distance from the base of the antennæ is a more abnormal arrangement. In a closely allied genus—Eucomatocera—the upper lobe is directly joined to the lower, a slight indentation marking the point of union. In Euthuorus and Spalacopsis, the upper lobe is wanting; while in Dorcasta and Aprosopus the eyes have nearly come back to their normal form. All these genera are clearly allied. The species described below differs, inter alia, from T. insignis, a species from Hong-Kong, Malacca, and Manilla, in its narrower form, and in the apices of its elytra being straight, not turned outwards.

Tetraglenes fusiformis.

T. fusca, griseo-lanuginosa; elytris apicibus recte acuminatis.

Hab.—Sarawak.

Pitchy-brown, thinly covered with short greyish hairs; head and prothorax finely punctured, the latter rather narrower than the head, abruptly sloped at the sides so as to present the appearance of lines; scutellum rather broad, covered with a silky pile; elytra more coarsely punctured than the prothorax, broadest behind the middle, the apices prolonged but not curved outwards; body beneath, legs and antennæ brownish-grey, the latter about as long as the body.

Length 4 lines.

POTHYNE.

Pothyne, J. Thomson, Syst. Ceramb. p. 97.

Caput paulo inclinatum, haud productum; tuberibus antenniferis validis, divergentibus, basi contiguis. Oculi mediocres, emarginati. Antennœ corpore longiores, fimbriatæ; scapo cylindrico, elytra fere attingente; articulo tertio sub-æquale; cæteris brevioribus. Prothorax cylindricus, inermis. Elytra elongata, parallela, apicibus sub-sinuatis. Pedes brevissimi, robusti; tarsi breves, æquales, articulo ultimo valido. Pro- et meso-sterna declivia.

These characters are drawn up from a specimen kindly sent to me by M. Thomson under the name of Pothyne Malasiaca, which differs somewhat from the description of his P. variegata. The head is not much inclined in this genus, nor is it produced at the base of the antennary tubers; in these respects it may be considered to approximate to the Saperdinœ, to which perhaps it might be more desirable to attach it. M. J. Thomson's species apparently differs from the one described below in its "elytra obsolete punctata."

SAPERDINÆ.

Saperda was one of the few genera formed by Fabricius out of the old Cerambyx, in which Linnæus, now exactly 100 years ago, had included all the Longicornia known to him, except Leptura and Necydalis.* The only character, however, which had a real existence in differentiating Saperda from Lamia—another of the Fabrician genera—was the unarmed prothorax of the former as contrasted with the spined one of the latter; and chiefly on this character M. Mulsant in 1839 divided his "groupe Clinocéphalides" (= Lamiidœ) into two families "Lamiens" and "Saperdins." M. C. G. Thomson (Skandinaviens Coleoptera, i. 152), whilst adopting this division, distinguishes the former principally by their clavate femora; and being thus obliged to admit Monochamus, which has nearly linear femora, into the Saperdinœ, he attaches a secondary importance to the prothorax. Both these authors deal with limited local faunas, but tested in a broader field the absence or presence of a spine or tooth on the prothorax is a far more valuable character than the clavate or linear femora.

The sub-family, as it is here limited, very nearly agrees with the Saperditœ verœ of M. J. Thomson's Systema; but with the addition of Serixia, which that author has arranged with the Amphionychinœ, notwithstanding that it has simple claws. Whether the Agapanthiinœ should be maintained as a distinct sub-family,

* Syst. Nat. ed. xii. The first species of Leptura, however, is a Donacia, and all the Necydales but three are Heteromera.

[page] 328

I must confess appears to me at present to be doubtful. M. Léon Fairmaire treats them as a distinct group, but if the subordinate divisions of the longicorn families were to be eleborated in the same way throughout the whole of their extent, several hundred such groups would be necessary, and I am not sure that this may not be found to be the most natural arrangement.

The leading characters of the Saperdinœ are as follows:—the intermediate tibiæ are very slightly or not at all emarginate, and never furnished with a tooth as in the more typical Lamiidœ; the prothorax is cylindrical and unarmed; the femora are linear or thickened in the middle, rarely clavate; and the pro- and mesosterna are simple. The head also is generally rounded in front, and not exserted; the antennæ are of moderate length, sometimes however very long, setaceous, and distant at the base; the feet rather short; the body compact and often slightly depressed, and the abdominal segments of unequal length. They are distinguished from the Obereinœ and Amphionychinœ by their simple claws, never appendiculate or bifid; and from the Hippopsinœ, to which many of their genera approximate, by the distant bases of their antennæ. It is sometimes difficult to distinguish some of the Apomecyninœ from the members of this sub-family, but the former often show traces of the prothoracic tooth which are not present in the Saperdinœ.*

The genera and species of Saperdinæ are numerous in the northern temperate region of both the old and new worlds. In the tropical portions of America, Amillarus is its only exponent, and this in Chili is replaced by Emphytœcia. In Africa we have Eunidia, Syessita, Chariesthes, &c. In Australia at this moment they are entirely unknown, and this fact affords another proof of the striking dissimilarity that exists between its beetle-fauna and that of the Malayan region, as Mr. Wallace's Collection alone contains thirty-five species, divided into eight genera. It must be observed, that the character drawn from the absence of emargination of the intermediate tibiæ is not absolute, but that a slight break in the continuity of the exterior edge is sometimes visible; as it is, the character serves to separate into two very natural categories the genera of the Malayan members of this sub-family, the first four having, moreover, a graduated approximation to the preceding sub-family, and the remainder to the Astatheinœ, which follow.

* On this account I refer Zygrita to the Apomecyninœ, where indeed M. J. Thomson originally placed it, rather than to the Saperdinæ, to which that authority has referred it in the more recent "Systema."

ZOTALE.

Caput parvum, supra paulo constrictum; tuberibus antenniferis approximatis. Oculi mediocres, late emarginati. Antennæ corpore duplo longiores, fimbriatæ; scapo brevi, sub-fusiformi, vel basin versus incrassato; articulo tertio plus duplo longiore; sequentibus fere æqualibus.

Pedes elongati; femora incrassata; tibiæ breviusculæ; tarsi intermedii et postici quam antici longiores. Prosternum simplex. Mesosternum elongatum, declive.

With its approximate antennary tubers this genus forms a passage to the Hippopsinœ, from which it essentially differs in its normally long and stout legs. The mesosternum, however, is much longer than obtains in the ordinary Saperdinœ, and it must be considered a rather unsatisfactory member of this sub-family.

In the work above quoted M. J. Thomson places this genus near Oberea, but in the more recent "Systema" (p. 94) he forms it into a distinct "groupe," putting it directly before his "Hippopsitæ." It is certainly not to be considered a legitimate member of this sub-family, but unless we adopt it as the representative of a distinct group, I do not see that it can be better placed. It is the genus Eusebis of Dejean's Catalogue.

Pro- et meso-sterna angustata, simplicia.

The affinities of this genus are not very evident. The linear antennæ with the white apical or sub-apical joints show an analogy with Nyctimene, but the legs are of the normal length and the tarsi are very different, in the latter respect resembling Serixia and Xyaste, near which it might be perhaps most naturally arranged.

ENTELOPES.

Entelopes, J. Thomson, Essai &c., p. 345.

Caput magnum, antice transversum, tuberibus antenniferis obsoletis. Oculi mediocres, profunde sinuati, supra remoti, lobis fere æqualibus. Antennœ corpore breviores, sub-filiformes, ciliatæ, basi distantes; scapo sub-elongato, apicem versus crassiore; articulo tertio sub-æquali; cæteris decrescentibus. Labrum elongatum. Prothorax brevis, cylindricus, capite angustior. Elytra convexa, breviter sub-ovata, prothorace multo latiora, apicibus singulis spina terminatis. Pedes breviusculi, validi; femora et tibiæ posticæ longiores, intermediæ integræ; tarsi breves, æquales. Pro- et mesosterna simplicia.

M. Guérin-Méneville in his "Iconographie" (p. 245) points out two or three characters by which this genus is distinguished from Astathes, perhaps quite enough, according to the usual practice, to fix him as the describer of it. As, however, there is no connexion between the two genera, and M. Guérin's remarks were not intended to be supplemented by any future description, it does not seem to me desirable that such a style should carry with it the same rights of priority accorded to a real attempt to characterize a new genus, and I have therefore referred to M. J. Thomson, who has given a full account of it, as the true authority for the genus. At the same time it is necessary to remark that his "Entelopes Wallacei, Pascoe," is the common E. glauca, a very distinct species, but why it is named "glauca" is not evident; M. Guérin says of it in his description "sans poil ni duvet," but all the species are covered with very delicate short scattered hairs. I am unable to agree with M. Thomson when he describes the anterior coxæ as being transverse. Entelopes is a beautiful genus, now consisting of five species, one of which from Penang (E. similis) I have recently described in the Proceedings of the Zoological Society (1866, p. 255).

Pedes breviusculi; femora et tibiæ posticæ longiores; tarsi breves, æquales, antici articulo primo secundo longiore. Pro- et meso-sterna simplicia.

In the Journal of Entomology (i. 354) I have proposed to unite Iolea to Serixia, the slight differences in the characters of the few earliest discovered species not being sufficiently constant to warrant their separation since so many more have been made known. M. James Thomson in his "Systema," however, not only maintains their distinctness, but places them in two different "groupes." The species vary considerably in size and coloration, and in the comparative length of the antennæ and the head appears to be much larger in some individuals than in others of the same species. They have nearly all a fine silky, mostly pale, pubescence, varying

[page] 336

according to the light, on a luteous, or occasionally dark brown or black, derm. On the prothorax there is a kind of sharp longitudinal elevation in the middle terminating posteriorly just before the base in a slightly abrupt point. The same character occurs in Entelopes and Xyaste. Besides the species described below there are a few specimens from Waigiou, Bouru, Sarawak and Sumatra, which are very close to some of these, but cannot at present be satisfactorily referred to any of them.

Hab.—Sarawak.

Head and prothorax reddish-luteous, sparingly pubescent, impunctate; scutellum transverse, slightly bilobed at the apex; elytra parallel, covered with a dense silky yellowish-grey pubescence, except on the sides, which are black, and on which alone the punctuation is visible, the apices reddish, each furnished with a slender spine; body beneath and legs luteous, the four basal segments of the abdomen black; antennæ twice as long as the body, black.

Hab.—Batchian, Morty, Saylee.

Pale reddish-testaceous, very silky and shiny; head and prothorax obsoletely punctured, covered with a short, slightly silky pubescence, the former often considerably broader than the prothorax; scutellum subtransverse, bilobed at the apex; elytra rather narrow, seriate-punctate anteriorly, pubescence coarse, greyish under the lens, but to the eye brownish-black, except at the base, the apices whitish, and rounded; body beneath and legs pale testaceous; antennæ more than twice as long as the body, blackish-brown, except the under surface of the scape and the base of the fourth joint.

Length 3½—4 lines.

The head varies in breadth and the antennæ in length. One of Mr. Wallace's specimens (ticketed ♀) has the elytra entirely of a rich fulvous-yellow; another specimen (♂) is so very silky as almost to lose the dark colour of the elytra in certain lights. From a slip of the pen, or in some other way, the scutellum was originally stated to be triangular; it is, however, as it is here described.

Serixia longicornis.

Iole longicornis, Pascoe, Trans. Ent. Soc. ser. 2, iv. 255.

S. fulvo-testacea, sub-sericea; elytris angustis, seriatim punctatis; antennis corpore triplo longioribus, tenuissimis, articulis duobus basalibus fuscis, cæteris fulvis, apicem versus gradatim nigricantibus.

scurely seriate-punctate, covered with a whitish pubescence, especially in certain lights, a large squarish humeral patch and the apical third blackish, the apices, however, with a nearly unvarying ashy whitish pubescence; body beneath and legs fulvo-testaceous; antennæ more than twice as long as the body, slender, blackish, the bases of the scape and fourth and fifth joints excepted.

Length 4 lines.

A female specimen from Morty closely resembles this species, but the elytra are entirely immaculate.

Serixia ornata.

Length 5 lines.

This is the only species of Serixia with the legs almost entirely black. One of my specimens is much darker, with the apices of

[page] 342

the elytra more acute, and the punctures larger than in the type, but in other respects I can see nothing to warrant its separation.

BACCHISA.

Characteres ut in Serixia, sed frons inter antennas cristata, oculi divisi, et antennœ crassiores.

The very remarkable and unique example on which I have founded this genus is at once distinguished by its divided eyes, independently of the strange crest which it bears in front, and which, even if it be generically characteristic, is perhaps only an appendage of the male sex.

Bacchisa coronata. (Pl. XV. fig. 11.)

B. rufo-lutea; antennis elytrisque nigro-chalybeatis.

Hab.—Flores.

Clear yellowish-red, the antennæ and elytra blueish-black; head impunctate, very broad in front, spreading out to the antennary tubers, which are very widely apart, the space between them concave, but sending up in the middle an erect squarish protuberance, slightly bilobed above, each lobe tipped with a pencil of long hairs, a similar but smaller pencil of hairs clothing each of the antennary tubers, an elevated line in front extending from the notch in the protuberance to the lip; eyes black; prothorax nearly obsoletely punctured; scutellum semicircular; elytra irregularly punctured, covered with a scattered coarse greyish pubescence, the apex rounded; body beneath and legs more luteous, the tarsi and ends of the tibiæ brownish; antennæ black, half as long again as the body, slightly hairy.

Caput mediocre, antice transversum. Oculi emarginati, lobo superiore multo minore. Antennœ corpore longiores, filiformes, scapo tenuiter cylindrico, articulo tertio incrassato, sequentibus brevioribus et æqualibus. Elytra paulo depressa. Prothorax, pedes, &c. ut in Serixia.

Besides the character of the antennæ, this genus has a more depressed and less compact form than Serixia. This, however, is more evident in some species than in others. The species scarcely very in size, and the pubescence is less silky than in Serixia.

ASTATHEINÆ.

The only author who has paid any attention to Astathes and its allied genera, M. J. Thomson, in his earlier work (Arch. Ent. i. p. 45), formed of them a "groupe" apart, named Tetraophthalmites, to which, however, he also attached Tetraopes, Tetrops and Tetraglenes, on account of their divided eyes. In the "Essai" (p. 66) they formed a "division" of the "sous-groupe" Apomecynitœ, under the name of Tetraopesitæ, with the addition of the genus Phæa. In the more recent "Systema," (p. 117) they became a "sous-division" of the Obereitœ, which is itself a "division" of the "groupe" Amphionychitœ. With the exception of Serixia, which I have already referred to the Saperdinœ, and Cleonaria, which is unknown to me, this subdivision corresponds with the Astatheinœ as here limited.

The most remarkable of the characters of the Astatheinœ consists in having the metasternum projected forwards between the intermediate coxæ so as to cover more or less completely the ventral surface of the mesosternum—the vertical portion only being visible. Unfortunately this character is present only in Astathes, Eustathes and Tropimetopa,* and it disappears entirely without any gradual modification in the remaining genera. Another character is the broad lobe found at the base of each of the claws; these appendiculate claws show themselves again in the Phytœciinœ. There is also another structural peculiarity to be noticed in the mentum and lower lip. These two are closely connected, so that it is difficult to trace any line of demarcation

* And in the African genus Ecphora.

[page] 348

between them; together they form a narrow, parallel, somewhat quadrangular organ, the two lobes of the lip united, and at their junction presenting a strongly-marked keel or rib. The labial palpi arise from two deep approximate depressions nearly midway, which may perhaps be taken as the line between the mentum and labium.* It may be also remarked that the anterior coxæ in the more typical genera are globose, passing only a little beyond their cotyloid cavities.

Except Ecphora, which is limited to a single species, the whole of this family are either Malayan or Indian, not many, however, extending beyond the former region. They are generally found flying or rather "floating slowly" over newly fallen timber. Tetraopes, an American genus, sometimes referred to this sub-family on account of its divided eyes, I regard as a member of the Amphionychinœ.

ASTATHES.

Astathes, Newman, Entom. i. 299 (1842).
Tetraophthalme, Blanchard, Hist. Ins. ii. 161 (1845).

Caput antice convexum, rotundatum; tuberibus antenniferis obsoletis. Oculi lobis remotis. Antennœ setaceæ, corpore breviores, basi valde distantes; scapo articulo tertio breviore, sequentibus gradatim decrescentibus, apice acuto.

* The species examined were Astathes nitens and flaviventris, Tropimetopa simulater, Cyanastus aulicus and Chreonoma tabida.

[page] 349

Prothorax in medio gibbosus, lateribus dentatus vel tumidus, postice sulcatus, basi bisinuatus. Elytra latiuscula, sæpissime tricarinata, apicibus rotundata. Pedes breviusculi, æquales; femora modice incrassata; tarsi breves; unguiculi basi appendiculati. Prosternum elevatum. Mesosternum metasterno omnino tectum.

The type of this genus, A. perplexa, Newm., is a Manillan insect, and is the only species known to me in which the prothorax is strongly toothed; in all the others there is merely a tumidity, which in some cases is very prominent, including a large part of the side; it is also one of the few species in which the lines on the elytra are scarcely or only slightly raised, although their places are indicated by the absence of punctures, and sometimes, of a very delicate line. All the species have a glossy derm clothed with short setose scattered hairs, but the coloration is often a little uncertain. Astathes perplexa, for instance, generally unicolorous, has sometimes a large violet spot on each elytron; and in others the blue or violet varies in extent, or becomes purplish. Nevertheless the disposition of the colours, which are mostly a combination of yellowish-testaceous or fulvous, violet or blue, and black, affords, in conjunction with other characters, a sufficiently satisfactory clue to the discrimination of the species. The gibbosity of the prothorax rises more or less gradually from the apex, and is often slightly notched behind. Generally the punctures on the head and prothorax are few and small; those on the elytra are in many individuals surrounded by a very evident deeply-coloured border—areolated as they have been termed—but other specimens, which do not appear to be otherwise different, have none or only very slight indications of this areolation. Species of this genus occur in Northern India, Northern China and in Japan, but Mr. Wallace does not appear to have found any east of Borneo.

Astathes unicolor.

A. flavo-testacea; antennis apice infuscatis.

Hab.—Sarawak.

Entirely yellowish-testaceous, except the apices of the antennæ, which are of the usual brownish colour, but rather paler than in the majority of species; the elytra with a slightly opaline tinge; gibbosity of the prothorax sloping gradually down in front to the apex and attaining its highest point nearly in the middle of the disk (in A. perplexa it is flattened and bilobed in front, without

attaining the apex); elytra with the lines well marked, areolæ of the punctures very close together; body beneath with roughish hairs.

Length 5½ lines.

M. J. Thomson's A. testacea (Arch. Ent. i. 55) differs in having the basal segments of the abdomen black.*

Astathes nitens.

Head, prothorax, scutellum, femora and the whole of the body beneath black; gibbosity of the prothorax flattened; elytra ful-

* I have recently received an insect from Labuan closely allied to the above, of which indeed it may possibly be only a variety, but besides the colour, which, on the elytra, is of a rich vermilion with decided blueish reflexions, it has the upper lobes of the eyes larger and more approximate, and the scape stouter. This beautiful species may be differentiated as follows:—
Astathes coccinea.

vous, with a narrow strip at the base and apex dark violet; palpi and tarsi fulvous, the tibiæ tinged with blackish; head and prothorax distinctly punctured, the pu´ctures thicker on the latter; elytra finely punctured.

Length 5—6 lines.

The Lamia Daldorfii of Illiger (in Wiedemann's Arch. für Zool. i. pt. ii. p. 136) includes three species, but I have here confined the name to the one described by Fabricius, which is at once differentiated by the violet apices and base of the elytra, and the body beneath entirely black.

Astathes posticalis.

J. Thomson, Syst. Ceramb. p. 558.

A capite prothoraceque nigris; elytris dimidio basali violaceis, cæteris flavis; postpectore flavescenti; propectore, femoribus, abdomineque fuscis.

Hab.—Sarawak.

Head, prothorax and scutellum black; basal half of the elytra violet, the remainder yellow; body beneath dark brown, except the meso- and meta-sterna, which, with the tibiæ, tarsi and antennæ, are pale yellowish, the latter darker at the tip; prothorax with the posterior groove deeply bisinuate, the gibbosity flattish, but with a short point behind the middle; elytra broad, punctures small, in one specimen areolated on the posterior half; femora black, tibiæ and tarsi yellowish.

Length 7 lines.

A broad, full-bodied species, the most so perhaps of the genus. Differs from A. ignorantinus, J. Thoms., in the body beneath and the four anterior legs being yellow, the posterior black. My specimens differ from M. Thomson's description in the lower part of the tibiæ and the tarsi being yellowish, not black.

Astathes terminata.

Pascoe, Trans. Ent. Soc. ser. 2, iv. 109.

A. capite prothoraceque nigris; elytris læte violaceis, parte apicali flavis; corpore infra femoribusque fusco-piceis; disco prothoracis sub-bicarinato.

Hab.—Singapore.

Head, prothorax and scutellum black; elytra violet, the posterior half or third yellow; body beneath dark pitchy-brown; femora paler; tibiæ and tarsi yellowish; antennæ pale yellow,

[page] 352

the scape pitchy; prothorax with the gibbosity slightly ridged on each side, each ridge deeply excavated anteriorly; elytra narrower than in the preceding, punctures small.

Length 6½ lines.

This is a flatter insect than A. posticalis, which it much resembles in colour, but is narrower, with the disk of the prothorax slightly keeled on each side of the gibbosity. Astathes ignorantinus, J. Thoms. (Arch. Ent. i. 51), differs in the body being yellow beneath.

Astathes flaviventris.

A. (♂) angustata; capite prothoraceque nigris; elytris violaceis, parte apicali flavis; pectore, femoribus tibiisque piceis; abdomine flavo.

Hab.—Sarawak.

Much narrower than either of the preceding, and scarcely differing in coloration from the last, except that the abdomen is bright yellow; prothorax without any point, the gibbosity simply rounded above and sinking on each side posteriorly; elytra finely punctured; scape and second joint of the antennæ pale chesnut, the last three or four joints black.

Length 5—6 lines.

The male is unusually narrow; the violet is sometimes replaced by purple.

Astathes contentiosa.

A. capite prothoraceque nigris; elytris purpureis, parte apicali flavis; corpore infra femoribusque purpureo-nigris, nitidis; disco prothoracis in medio oblongo-tuberculato.

Hab.—Singapore.

Head and prothorax black; basal half of the elytra purple, the remainder yellow, the two colours limited in an oblique direction from the middle of the suture outwards; body beneath and femora glossy purplish-black; antennæ, tibiæ and tarsi yellowish, the former pitchy at the base and brownish at the apex; prothorax only slightly elevated on the disk, the middle with an oblong tubercle strongly punctured on each side.

Length 5 lines.

I have only seen a single example of this species, which agrees pretty much in colour with A. terminata, but is at once distinguished by its prothorax.

[page] 353

Astathes fulgida.

? Cerambyx fulgidus, Fabricius, Syst. Eleuth. ii. 280.

A. capite prothoraceque pallide flavis; elytris totis læte violaceis.

Hab.—Sumatra.

Entirely pale yellow, except the elytra, which are of a very rich dark violet; head flattened between the tubers, projecting in front between the eyes; prothorax with an oblong gibbosity well limited at the sides and posteriorly by a broad but somewhat shallow groove, the apex nearly in the centre, punctures few and confined to the gibbosity; scutellum very transverse; elytra with fine well-marked ridges, the outermost forming an angle with the nearly vertical sides.

Length 6 lines.

I have only a single specimen, with which the description of Fabricius agrees so far as it goes, except that the pale yellow becomes ferruginous. M. J. Thomson's A. cyanipennis "paulo revocat A. fulgidam," but the ferruginous is replaced by black. It is from the Celebes (Syst. p. 557).

Astathes velata.

A. capite, prothorace, elytrisque fulvis, his ad humeros læte violaceis; corpore infra pedibusque fulvis.

A. capite prothoraceque fulvis; elytris dimidio basali violaceis; corpore infra pedibusque fulvescentibus.

Differs from A. velata in not having the violet interrupted at the suture. Astathes decipiens, Pasc. (Trans. Ent. Soc. ser. 2, v. 46), not in Mr. Wallace's collection, differs, inter alia, in the nearly obsolete punctuation on the apical portion of the elytra.

Astathes purpurea.

Pascoe, Trans. Ent. Soc. ser. 2, iv. 108.

A. capite prothoraceque nigris; elytris totis purpureis; antennis tarsisque testaceis.

Hab.—Singapore.

Head and prothorax black, the rest of the insect dark purple, except the antennæ, metasternum and tarsi, which are testaceous, the former slightly pitchy at the base; prothorax with the point of its gibbosity in the middle, a large fovea in front nearly intermediate between the point and anterior border; elytra with two well marked ridges, the third close to the suture, and almost confounded with it.

Length 5 lines.

Another species allied to this, but not in the present collection, has been described by me under the name of A. caloptera (Journ. of Entom. i. 63). It is from Labuan, and has the elytra of the richest imaginable blue, with violet reflexions in certain lights.

Astathes pulchella.

A. angustior, flavo-ferruginea; elytris dimidio basali læte violaceis, postice flavis; medipectore fusco.

Hab.—Sumatra, Malacca.

Narrower than any of the preceding, reddish-fulvous, the basal half of the elytra violet or blue, apical half gamboge-yellow; head and prothorax covered with very distinct, somewhat scattered punctures, the latter with the central callus raised at the base only; scutellum transverse; elytra finely punctured; body beneath yellowish, the medipectus dark brown; antennæ with the two or three terminal joints blackish; legs entirely yellowish.

Length 4—6 lines.

EUSTATHES.

Eustathes, Newman, Entom. i. 300.

Characteres ut in Astathe, sed antennœ sub-lineares, prothorax bicarinato-callosus, metasternum apice in sinu mesosterni receptum, corpus minus amplum, elongatum.

The real difference between this genus and the preceding appears to me to reside in the modification of the mesosternum, which here rises to the level of the metasternum, and forms a kind of small sinus or indentation which receives the apex of the latter. Besides this character, the gibbosity on the disk of the prothorax

[page] 355

is bounded on each side by a longitudinal curved ridge, with its concavity outwards. The sublinear antennæ also are probably a good although somewhat difficult character to seize. Mr. Newman notices none of these points, the only strongly contrasted peculiarity being the long parallel elytra of this and the broad elytra of Astathes. The new species described below differs, inter alia, from the type (E. flava) in the posterior third of the elytra being black, and the abdomen and legs fulvous.

Eustathes semiusta.

E. fulva, vel rubro-fulva, antennis elytrisque postice nigris.

Hab.—Amboyna.

Fulvous or reddish-fulvous, finely pubescent, the posterior third or a little more of the elytra, black; head with a slight semicircular or rather horse-shoe-shaped raised line between the eyes, the convexity downwards, the front obscurely punctured; prothorax impunctate, the ridges glabrous, black and shining; scutellum semicircular; elytra finely and irregularly punctured, the longitudinal lines only slightly elevated; body beneath and legs fulvous, the outer edges of the intermediate tibiæ, in one specimen, bordered with black hairs; antennæ black, a little shorter than the body in the male.

Length 6 lines (♂), 8 lines (♀).

CYANASTUS.

Caput et oculi ut in Astathe. Antennœ corpore breviores, basi valde distantes; scapo articulo tertio longiore; secundo paulo elongato; quarto et sequentibus gradatim decrescentibus. Prothorax haud callosus, lateribus tumidus, basi bisinuatus. Elytra convexa, ampla, haud carinata, postice latiora, apice rotundata. Pedes mediocres; tibiæ subæquales. Prosternum demissum, angustatum. Mesosternum angustatum, declive, metasterno haud occultum. Metasternum valde convexum. Corpus amplum.

The habit of this genus is very similar to that of Astathes, but the body is in no respect depressed. In its technical characters, however, it is more nearly allied to Chreonoma, differing principally in its longer and more cylindrical scape, the bisinuate base of the prothorax, and very convex outline. The two species described below agree in coloration, but the prothorax of the second is dif-

A A 2

[page] 356

ferently shaped from that of the type. Both species are thinly covered with short stiffish erect hairs.

Cyanastus aulicus. (Pl. XVI. fig. 2.)

Hab.—Macassar.

Fulvous, shining, elytra bright glossy blue, blackish and opaque on each side behind the shoulders; head and prothorax finely punctured, each puncture furnished with a stiffish erect hair, base of the antennary tubers and sometimes the middle of the prothorax spotted with black; scutellum semicircular, yellow; elytra finely punctured, clothed with short erect hairs, especially at the sides; body beneath and legs yellow, hairy, the tibiæ and tarsi blackish or blueish; antennæ yellowish, the outer side of the basal joints and apex blackish.

Length 7 lines.

Cyanastus simius.

C. fulvus, elytris læte cyaneis; prothorace modice transverso, antice vix angustiore.

Hab.—Menado.

Differs from the former in the narrower prothorax, the apex and base nearly of the same breadth, and the lateral tumidity very much smaller; the elytra also are less convex.

TROPIMETOPA.

Tropimetopa, J. Thomson, Syst. Ceramb. p. 118.

Characteres ut in Astathe, sed caput antice inter oculos bicarinatum; elytra depressa, breviuscula, ampla, haud carinata, apicibus spinosis.

M. J. Thomson separated this genus from Hecphora (or as it should be written Ecphora) on account of the presence of two frontal ridges—one at the base of each antenna—and the depressed spined elytra. The former character, however, is found, although in a less degree, in Ecphora testator (an African species). Still, when we take into account the gibbous prothorax of Ecphora, prolonged posteriorly so as nearly to cover the scutellum, and contrast it with that of Tropimetopa, which is nearly of the same form as in Astathes, we cannot hesitate to adopt the genus.

[page] 357

Tropimetopa simulator.

Astathes simulator, Pascoe, Trans. Ent. Soc. ser. 2, iv. 44.

T. brunneo-rubra, subnitida; antennis apice nigris.

Hab.—Sarawak.

Brownish-red, or in certain lights miniaceous, slightly nitid, covered above with short scattered erect hairs; head and prothorax finely punctured, the latter with an elevated squarish somewhat bilobed gibbosity; scutellum punctiform; elytra finely and irregularly punctured, the apex of each terminating at the sutural angle in a slightly oblique spine; body beneath and legs reddish-ferruginous, shining; antennœ nearly as long as the body in the male, pale ferruginous, the apex dark brown or black, the first two joints nearly glabrous, with a few longish hairs, the rest pubescent, fringed beneath.

Length 4 (♂)—5 (♀) lines.

OCHROCESIS.

Characteres ut in Chreonoma (post, p. 358), sed elytra angustata, parallela, apicibus spinosis.

It must be admitted that this genus is rather weakly characterized, and it might perhaps be viewed simply as an aberrant form of Chreonoma, nevertheless the spined apices of the elytra are so exceptional, occurring only again in this sub-family in Tropimetopa, that I think its separation will lead to a better appreciation of the genera, and serve to make Chreonoma a more nearly homogeneous group. There are two specimens. In the smallest one, probably the male, the antennæ are a trifle longer than the body; in the other, they scarcely reach to the end of the elytra.

Ochrocesis evanida. (Pl. XVI. fig. 3.)

O. testacea, postice dilutior; antennis apicem versus nigris.

Hab.—Sarawak.

Testaceous, paler posteriorly, clothed with numerous pale greyish, nearly erect, hairs; head and prothorax vaguely punctured, the latter without any median prominence; scutellum indistinctly separated from the elytra; the latter with well-marked punctures at the base, disappearing towards the apex; body beneath fulvous, the metasternum and its episterna blackish; legs and antennæ testaceous, the latter blackish at the spines.

Length 3—3½ lines.

CHREONOMA.

Caput et oculi ut in Astathe. antennœ corpore breviores, basi distantes; scapo breviusculo, apicem versus crassiore; articulo secundo paulo elongato; tertio sæpissime scapo longiore; quarto et quinto tertio longioribus; cæteris brevibus. Prothorax in medio subcallosus, lateribus paulo tumidus, basi fere rectus. Elytra haud carinata. sæpe breviuscula, parallela vel postice paulo latiora, lateribus nullo modo dilatatis. Pedes ut in Astathe. Prosternum demissum, angustissimum. Mesosternum angustatum, declive. Metasternum liberum.

Of the two species of Plaxomicrus (potius Placomicrus) originally described by M. J. Thomson (Arch. Ent. i. 57) one may be referred to Chreonoma; the other—P. ellipticus—standing as the type, according to the author's latest arrangement in his "Systema." M. Thomson, however, sinks his name as a synonym of M. Chevrolat's Astathes Fortunei, of which I cannot find any published description. I cannot help thinking that there is a mistake here, and that the two are perfectly distinct, the latter belonging to the present genus. The species described below are all of small size compared with Astathes, and are sparsely clothed above with short erect hairs, each issuing from a puncture in the derm; the elytra are generally punctured at the base only, the punctures nearly disappearing or becoming smaller towards the apex; the scutellum fits so closely to the elytra as to be made out with difficulty; the second joint of the antennæ, generally so very short, is here, as in Cyanastus, two or three times longer than its diameter.

PHYTœCIINÆ.

Since the commencement of this work I have examined a long series of specimens of the two great genera Glenea and Oberea, and their cognate forms, but however different the most typical species of the two groups may appear to be, I have come to the conclusion that there is no satisfactory division to be made between them, Scytasis, for example, combining the prominent characters of both; while there are other genera with their characters so mixed that there is obviously nothing to be gained by separating them from the true Phytœciinœ. It may be a question even if the Amphionychinœ are sufficiently differentiated by their double or deeply-cleft claws, in contradistinction to the dentate or simply appendiculate claws of the Phytœciinœ. The abruptly-deflected sides of the elytra, which are supposed to characterize the former, are found in many genera of the latter, so that the structure of the claws appears to afford a safer diagnosis between the two groups.

Taking then the three genera Phytœcia, Glenea, and Oberea, with their allies, as forming one sub-family, its most salient characters are found in the claws having a flattish tooth or appendage at the base of each, a peculiarity which is structurally scarcely different from the bifid claw of the Amphionychinœ, the inner branch being merely abbreviated, and rounded off or more or less obtuse at the edges: in their greatly exserted anterior coxæ, which are sometimes perfectly conical, as in Nitocris: and frequently in

[page] 363

their abruptly-deflected elytra, which, in the few species of Glenea with simple or nearly simple claws, will distinguish them from Saperdinœ.

While the Amphionychinœ are confined to tropical America,* the Phytœciinœ are spread over the rest of the world, except Australia and probably many or most of the Pacific Islands. When we consider that Mr. Wallace detected above 160 species of this sub-family in New Guinea and other parts of the Malayan Archipelago, we cannot but be struck with its entire absence from Australia; but it is only one among many instances which go to prove how thoroughly distinct are the beetle-faunas of the two regions. In the present Collection the great bulk of the species is confined to Glenea and Oberea. The latter genus is known in Europe. The 163 species here described I have distributed into ten genera, but a few Obereœ remain for further examination.

GLENEA.

Sphenura, Laporte de Castelnau, Hist. Nat. Ins. ii. 489 (non Lichtenstein). Glenea, Newman, Entom. i. 301.

Caput antice paulo rotundatum, inter oculos canaliculatum. Oculi mediocres, anguste emarginati. Antennœ distantes, corpore rarissime breviores (♂), obsolete articulatœ, scapo cylindrico, articulo tertio cæteris multo longiori, sequentibus paulo sensim decrescentibus. Prothorax cylindricus, supra quadratus, postice lateraliter parum constrictus, basi haud sulcatus. Elytra trigonata (♂), magis parallela (♀), disco subdepressa; carina fere obsoleta sæpe instructa; humeris productis; lateribus carinato-deflexis, raro carina obsoleta; apicibus emarginatis vel truncatis, bispinosis (G. Thomsoni excepta). Pedes modice elongati, postici longiores; femora haud clavata; tibiæ paulo trigonatæ; tarsi æquales, aliquando postici paulo longiores. Ungues in maribus simplices, sed generaliter obtuso-dentati, aliquando acuto-dentati (e. g. G. Amboynica, G. cyanipennis, etc.). Pro- et mesosterna simplicia. Abdomen segmentis tribus intermediis brevioribus.

This genus was first described by M. de Castelnau in 1840, under the name of Sphenura, a name previously used for a genus of birds, and was founded on S. novemguttata of Dejean's Catalogue. Mr. Newman, in 1842, changed the name to Glenea, and described several new species from the Phillippine Islands; and M. J. Thomson,* in his various works, has since added a very

* In the "Archives Entomologiques," Glenea was treated as identical with Stibara, Hope, but subsequently it was considered by M. Thomson to be sufficiently differentiated by its tumid prothorax, to which may be added the bicarinated disk of the elytra, and the stouter and more distinctly articulated antennæ; the two last characters would, however, exclude Lamia nigricornis, Fab. (Ent. Syst. i. pt. 2, p. 270), hitherto included in it. This species has also a habit so peculiar that, I think, it should form the type of a distinct group, which may be named and characterized as follows:—
NICOTELEA.
Caput antice quadratum; oculi mediocres. Antennœ robustæ, breviusculæ, articulis cylindricis. Prothorax lateraliter tumidus, disco irregulari. Elytra dorso planata, haud carinata, lateribus subito deflexis, apicibus truncatis. Pedes robusti, postici paulo longiores. Pro- et meso-sterna simplicia.
Type Nicotelea nigricornis, Fab. India, Ceylon.

[page] 365

considerable number to the list. Although there is a sufficiently natural resemblance running through the whole of the species, so that they may be recognized at a glance, we feel our ideas of the generic boundary somewhat disturbed when we observe the great discrepancy which exists if some of the species be compared with others, for example, G. picta with G. miles, or G. Vesta with G. Delia. Nevertheless there appear to be no characters by which a satisfactory separation may be made. The division of the species by intervening lines, which I have made in the attempt to indicate their affinities, is one chiefly dependent on colour, and colour in this genus, so far as it depends on ornamentation, is to a certain extent variable. In the species whose trophi I have examined with the hope of finding some reliable characters, the labium was more or less hexagonal, its palpi arising from a little within the two lateral angles, the last joint being fusiform and pointed, but in G. citrina I found the labium ovate, with its palpi very short, and the last joint very stout and broadly truncate. In two nearly allied species, however,—G. spilota and angerona,—the palpi are of the normal form. The dorsal extremity of the anal segment of the abdomen of the males is often furnished with two processes, varying in size, close together, or divergent; these and the ædeagus might perhaps furnish reliable characters for the discrimination of closely allied species.

Many of the Gleneæ are very striking and handsome insects. Mr. Wallace informs me that they are found in sunny glades in the forests, settling on leaves, rarely more than one individual being seen at a time, and they fly off rapidly when disturbed. They are almost entirely confined to the Malayan region and to West Africa, none, so far as I know, being found in South Africa* or in Australia; but from the former region they extend to Northern India, China† and Japan, although in

A nearly allied genus, however, distinguished by its antennæ gradually thicker towards the apex, and its abdomen composed of segments nearly equal in length and the small size of the interfemoral process of the basal one, seems tolerably abundant in species—although very rare as to individuals—in Natal and at the Cape. I propose to call it "Blepisanis;" the type is Saperda Bohemani. It will include several new species, which I hope to publish very shortly; one of them has a remarkable spine on the second abdominal segment.

† A species from Northern China, published by Mr. W. Wilson Saunders (Glenea Fortunei), has been recently separated from that genus by Mr. Bates under the name of Paraglenea; a second species from Formosa was described at the same time (Proc. Zool. Soc. 1866).

[page] 366

very diminished numbers; in another direction a species has been described by M. Thomson from New Caledonia. Glenea grisea and Glenea fulvomaculata were once found together, so as to lead Mr. Wallace to infer that they were male and female; we have, however, positive proof that some insects at certain times do not know what they are about, or at least that they are not very fastidious, and I suspect G. grisea is one of them.

smaller, with a broad conspicuous greyish stripe along the suture, and the base of the elytra with a blue spot on each side, but no other character apparently of specific importance; still it has, primo visu, a very distinct appearance.

Glenea laudata.

Glenea viridi-notata, J. Thomson, Ess. &c., p. 52 (non Blanchard).

G. nigrescens, subnitida, cœruleo-vittata et maculata; prothorace in medio latiori (♂, ♀).

Hab.—Sarawak.

Blackish, subnitid, coloration almost entirely as in the last, but the elytral spots larger, and the form of the prothorax different, i. e. rounded at the sides or gradually swelling out from the apex to the middle, then narrowing to the base; the male is much stouter, with shorter antennæ than the one last mentioned, and there is not the slightest appearance of a sutural vitta.

Length 4½ (♂)—6 lines (♀).

In my specimens the blue is of the purest cobalt; M. Thomson terms it "griseo-cyanea."

Glenea Camilla.

G. vertice chalybeato; prothorace albescente, maculis duabus nigro-chalybeatis ornato; elytris cyaneo-chalybeatis, maculis sparsis margineque apicali albis.

Hab.—Sumatra.

Cheeks and border round the eyes white, front and vertex steel-blue; prothorax whitish, its disk nearly covered by two dark steel-blue spots; scutellum blue, somewhat semicircular, its apex pointed; elytra light steel-blue, purplish posteriorly, each with about five small round white spots, and a short line towards the apex, the latter with a distinct white border; body beneath steel-blue, the edges of the sterna and abdominal segments covered with a whitish pubescence; femora, tibiæ and posterior tarsi luteous, the fore and intermediate tarsi dark blue, all covered with a whitish pubescence.

Length 7 lines.

This species may be considered to connect the novemguttata series with the Amboynica series.

Hab.—Sarawak.

Head covered with a dense white or yellowish-white pubescence, except a large chalybeate spot in front and the hind-head; prothorax chalybeate, with two spots on each side, and two on the median line, one apical, the other basal, yellowish-white; scutellum black, the apex white; elytra lightish brown, chalybeate at the shoulders and darker posteriorly, each with three or four small round white spots, the emargination of the apex faintly bordered with white; body beneath chalybeate-blue, spotted with white; femora luteous, their apices, tibiæ, and tarsi, dark chalybeate, with a greyish pile; antennæ black.

Length 8 lines.

Glenea Nicanor.

G. vertice prothoraceque nigro-chalybeatis, hoc ochraceomaculato; elytris brunneo-flavis, albo-maculatis; pedibus omnino luteis.

Hab.—Macassar.

Head glabrous, chalybeate, except the cheeks, lower part of the front, and a small spot close to each upper lobe of the eye, which are covered with a yellowish pubescence; prothorax chalybeate, with six ochraceous spots, which are arranged in the same way as in the last species; scutellum black, its apex whitish; elytra pale brownish-luteous, metallic green at the shoulders, blackish posteriorly, each with five irregular whitish spots, the apices broadly margined with whitish; body beneath chalybeate, varied with yellow patches, the edges of the abdominal segments also more or less bordered with yellow; legs entirely luteous; antennæ black.

Length 8 lines.

It is possible that this species is only a local variety of the last, but it is at once distinguished by its entirely luteous legs, besides other differernces in coloration, and by its more coarsely punctured elytra.

Glenea iridescens.

G. capite prothoraceque chalybeatis, albo-tomentosis; elytris æneo-metallicis, apicem versus purpureis; femoribus posticis, apice nigro excepto, luteis (♀).

Hab.—Malacca.

B B 2

[page] 372

Head and prothorax dark chalybeate, with a thin whitish tomentum, but thicker and forming spots on the cheeks, front and base and sides of the prothorax, the latter with a broad but well marked longitudinal elevation posteriorly; scutellum elongate, rounded posteriorly, chalybeate, the apex white; elytra brassy, very dark at the base, yellowish in the middle and passing into rich purple, with blueish reflexions towards the apex, a few spots on the basal half composed of a short whitish pubescence; body beneath purplish or blue, glabrous, with indefinite white spots, arranged in two lines along the middle of the abdomen, and with irregular stripes on the sterna; legs chalybeate-black, the posterior femora, except at their apices, luteous; posterior tarsi and lower portion of their tibiæ dull luteous; antennæ in the female very little longer than half the length of the body.

Length 11 lines.

This very distinct species is remarkable, in the female at least—the only sex known to me—for the shortness of its antennæ G. leucospilota, Westw. (Colobothea), has the same robust form, but is considerably shorter, and bright green with white spots on the elytra. It is from Manilla.

Glenea Juno.

J. Thomson, Syst. Ceramb. p. 560.

G. valida, nigro- vel cyaneo-chalybeata, niveo-maculata; scutello elongato-triangulari; elytris basi dilatatis, sutura in medio alba.

Hab.—Singapore, Sarawak.

Stouter than any of the preceding, with the elytra much shorter in proportion to the length, and considerably broader at the base; the prothorax gradually widening posteriorly, with its sides nearly straight, the disk rather sparingly punctured; scutellum elongatetriangular; elytra with the suture white in the middle and connected with a large transversely oblong spot on each side, together forming the figure of a cross; outer spine at the apex well marked.

Length 11—13 lines.

At once distinguished by the large cross-shaped figure in the middle of the elytra, and by its more robust outline. One of my specimens is almost black, with the same white spots, however, as in the normal examples.

[page] 373

Glenea Honora.

G. valida, purpurea; prothorace basi constricto; scutello subscutiformi; elytris singulis maculis quatuor niveis ornatis (♀).

Hab.—Penang.

Rather short and stout, dark purple with white spots; head sparsely punctured in front; prothorax gradually contracting posteriorly, the base decidedly narrower than the apex, the disc and sides striped as in G. picta; scutellum subscutiform, broadly rounded at the apex; elytra broad at the base, each with four white spots, the second from the base nearly central; body beneath with white spots.

Length 9—10 lines.

In coloration this differs from G. picta in having only four instead of five spots on each elytron, and from all the preceding in the form of the prothorax. It seems to be a good species, judging from the two specimens before me.

Glenea voluptuosa.

J. Thomson, Ess. &c., p. 49.

G. elongata, cyaneo-chalybeata, niveo-maculata; scutello æqualiter triangulari; trochanteribus rufescentibus (♀).

Hab.—Singapore.

Not quite so narrowly elongate as G. picta, the prothorax more parallel at the sides, or even narrower at the base, the sides a little irregular in outline, the disk more distinctly punctured, although the punctures are partially hidden by the pubescence in some examples, and are found also extending to the sides; the trochanters reddish-yellow.

Length 10—12 lines.

M. Thomson gives also, as diagnostic characters, the head black, the elytra with two stripes on each at the base, and the apical spot resembling the number 7 reversed; the latter is constant in my specimens, but the two former vary; the reddish trochanters also appear to be constant.

Hab.—Ceram, Gilolo, Tondano, Key, Batchian, Dorey, Saylee (and Sumatra).

Narrow and elongate, dark chalybeate-blue, shining; head sparsely punctured in front, the rest nearly impunctate, two white stripes extending from the lip to the vertex, another behind each eye, and a spot on the cheek; prothorax nearly impunctate,* the sides subparallel, three white stripes on the disk, a brown stripe also above the coxæ on each side; scutellum narrowly triangular, pointed below, black, with a large, somewhat heart-shaped, white patch in the middle; elytra not much expanded at the shoulders, sparingly punctured, the punctures disappearing posteriorly, each with 5—7 white spots, arranged longitudinally, the 2nd and 4th often divided; body beneath more or less spotted with white, the epimera and sterna sometimes almost entirely white; trochanters blueish; legs with a delicate whitish pubescence, denser on the tarsi.

Length 12—15 lines.

The remark of Fabricius, "Magnus in hoc genere," inclines me to consider this the species he had before him. It is also the most widely distributed, and not likely, therefore, to have been unknown to him.

Coloration as in G. picta, but smaller and proportionately narrower; the sides of the prothorax straight and evidently broader at the base; in the Macassar specimen longer, finely pubescent, and having a very decided longitudinal ridge, three characters which are less apparent in the Dorey one; the scutellum, however, is decidedly rounded at the apex, although in both species it is very much covered by the comparatively long hairs forming the white patch, and which apparently is never absent. This

G. angusta, cyaneo-chalybeata, niveo-maculata; scutello anguste triangulari; prothorace interrupte punctato (♂, ♀).

Hab.—Singapore, Amboyna?, Dorey?.

Coloration similar to G. picta, but the elytra, equally narrow and slightly incurved along the sides, taper more towards the apex, characters which give this species an outline somewhat different; in the Singapore specimens this is accompanied with a narrowly triangular scutellum, and a prothorax rather strongly punctured, but the punctures in patches divided by smooth spaces; the Dorey and Amboyna specimens have, however, scarcely any trace of punctuation, and the scutellum is decidedly broader, although they are all similar in outline.

Length 8½—10 lines.

Glenea Delia.

J. Thomson, Ess. &c., p. 48.

G. cyaneo-violacea; prothorace albo-trivittato; elytris angustatis, albo-maculatis, humeris obsoletis.

Hab.—Sarawak.

Dark blueish-violet, front and vertex with two white, prothorax with three narrow white stripes; scutellum elongate triangular; elytra very narrow, the shoulders obsolete, each elytron with a short basal stripe and six or seven small whitish spots, a transverse paler spot near the apex, which is also bordered with white; body beneath violet, with white patches; legs violet, posterior tibiæ at the apex and their tarsi fulvous; antennæ black.

Length 9 lines.

This is a very narrow species, with the shoulders obsolete or without the angle which distinguishes every other member of this extensive genus; the antennary tubers are also approximate; nevertheless, so intimate is its affinity with the preceding that these strong peculiarities can only be regarded as of secondary importance.

Glenea Thomsoni. (Pl. XVII. fig. 1.)

G. cyaneo-chalybeata, cœruleo-varia; apicibus elytrorum in medio spinosis (♂, ♀).

Hab.—Batchian.

Dark chalybeate-blue; head with a few small scattered punctures in front and on the vertex, margin beneath the lower part of the eye pale blue; prothorax nearly impunctate, the sides slightly rounded, a large semicircular band extending from the base to the sides, where it is continuous with the band baneath the eye, whitish or pale blue; scutellum subscutiform, whitish or pale blue, except at the two anterior angles; elytra broad at the base, gradually narrowing posteriorly, the apex of each terminating in a single median spine, a large, somewhat lozenge-shaped ring in the centre, but extending to the external margins, either ochraceous or pale blue, behind the ring a pale blue oblique stripe extending from the suture outwards and downwards; body beneath with pale blueish patches, especially at the sides of the abdominal segments, the lateral patches in one specimen ochraceous; antennæ and legs dark blue, with a slight pale blueish pubescence.

Length 9 (♂)—12 (♀) lines.

Very distinct from all other species of this genus on account of the single median spine terminating each of the elytra. I have only a male and female, the latter on account of its size and the clear ochraceous ring on the elytra surpassing the former in beauty, and ranking perhaps as one of the most elegant of the Longicorns. I have much pleasure in dedicating it to M. James Thomson.

G. fronte capitis ochracea; prothorace supra ochraceo, macula magna atra in medio sita; elytris nigro-violaceis, maculis niveis octo ornatis (♂, ♀).

Hab.—Ceram.

Front of the head ochraceous, posterior part of the vertex, and base on each side of the prothorax, chalybeate-blue; prothorax ochraceous, the disk with a large black median patch; scutellum black; elytra violet or blackish-violet, each with four round snowy-white spots, the first and third of which are nearest the suture, the latter nearly midway, the fourth at about two-thirds of the distance, between the base and apex; body beneath and legs luteous; antennæ black.

Length 8 lines.

Resembles the two preceding, but is at once distinguished by its spotted elytra, in which it agrees with G. novemguttata. The cheeks in one of my specimens are chalybeate-blue, in the other white. The anal processes are dilated and nearly contiguous.

of the head and a central pentagonal spot on the prothorax jet-black; scutellum black at the base, white at the apex; elytra blueish, shading into purple in certain lights, the suture and two indistinct abbreviated basal stripes on each, whitish; body beneath whitish at the sides, the middle of the breast and abdomen luteous, sides of the latter below the white stripe chalybeate-blue; legs clear luteous; antennæ black.

Length 6½ lines.

This species has the black patch in the middle of the prothorax, by which it differs, inter alia, from G. bimaculicollis.

Glenea cyanipennis.

G. capite prothoraceque albis, hoc macula magna atra in medio sita; elytris cœruleis, albo-pubescentibus, maculis albidis octo ornatis (♂).

Hab.—Key (and Aru).

Head and prothorax white, tinged with ochraceous, the latter with a large angular median jet-black spot; scutellum blackish; elytra pale blue, clothed with a greyish-white pubescence, concealing the blue in certain lights, each having four indistinct round whitish spots, arranged as in G. amboynica; breast covered with a white pubescence, abdomen and legs glabrous, luteous; antennæ black.

Hab.—Dorey, Salwatty, Waigiou, Mysol.

Head and prothorax dirty white, the former with a spot in front and the vertex black; a black patch on the latter, varying in size, and either in the middle or before it and touching the apex; scutellum nearly semicircular, black; elytra reddish-luteous, with a broad black median band or patch, the shoulders dark blueish-purple, shining, or more or less entirely blueish-purple, except the

[page] 379

black band; body beneath reddish-luteous, the last abdominal segment with a black spot; legs reddish-testaceous or dark brown, the femora generally of the former colour, with a black line along the upper edge; antennæ reddish or black.

Length 5—6½ lines.

A variable species, the black elytral band, however, being apparently constant. The female has the claws considerably dilated at the base, but not fissured as in the male. The anal processes are stout and incurved.

Glenea mesoleuca. (Pl. XVII. fig. 4.)

G. atra, prothorace postice et vitta irregulari in medio elytrorum albis; pedibus luteis, griseo-pubescentibus (♂).

Hab.—Singapore.

Covered above with a dense jet-black tomentum; head large, the cheeks and line in front of the eye white; prothorax with a well limited pure white band posteriorly; scutellum rather narrow; elytra with an irregular stripe and a præ-apical spot, together somewhat resembling the note of interrogation on each elytron (the right-hand one reversed), the upper part of the stripe close to the suture; body beneath ashy, sides of the metasternum and abdomen white; legs luteous with a greyish pubescence; antennæ black.

Length 8 lines.

The head of this species, which is very distinct, is decidedly larger than is usual in this genus.

Glenea Galathea.

G. capite prothoraceque albis, illo vertice et linea frontali, hoc plaga bilobata mediana, atris; elytris atris, linea suturali pone medium in fascia lata currente, scutelloque albis (♂).

Hab.—Malacca (and India, Japan).

Head whitish, the vertex and line between the eyes black; prothorax white with a yellowish tinge, the centre with a large black bilobed or obcordate patch, connected with the anterior border; scutellum, and a stripe on the suture running into a broad band behind the middle, whitish or yellowish-white, the apex of each elytron with a faint ashy patch; sides of the sterna, the two basal and the terminal segment of the abdomen, glossy black; metaster-

num and third and fourth segments, except in the middle, white; legs and antennæ black.

Length 6 lines.

This species, described by M. Thomson from individuals from Japan, agrees exactly with my Malacca specimens, and also with another from India. Glenea Canidia from Bombay, and G. Mouhotii from Laos, are probably varieties, at least there are intermediate forms in the British Museum, one of which, from Siam, has the elytra almost entirely black.

Glenea collaris.

Pascoe, Trans. Ent. Soc. ser. 2, iv. 258.

G. vertice prothoraceque atris, hoc postice albo; elytris fusco-olivaceis, sutura vittaque externa grisescentibus (♀).

Hab.—Sarawak.

Front of the head and cheeks whitish, vertex and anterior portion of the prothorax jet-black, the posterior portion, rather more than half, opake-white or with a slightly ochraceous tinge; scutellum and elytra olive-brown, a narrow stripe along the suture, and another extending from the shoulder to near the apex, pale greyish; body beneath whitish, with three luteous stripes on the metasternum and abdomen; femora and bases of the tibiæ luteous, the rest and tarsi brownish with a whitish pile; antennæ black.

Length 7 lines.

M. Thomson proposes to alter the specific name to Donovani, Donovan having previously described a Saperda under the name of collaris. If such a rule were absolute it would be necessary to change the name of every species in the family of which the specific name had been reproduced.

Glenea Manto.

Pascoe, Proc. Zool. Soc. 1866, p. 262, pl. xxviii. fig. 7.

G. vertice prothoraceque atris, hoc postice, elytrisque plaga media communi et maculis duabus apicalibus, albis (vel ochraceis).

Hab.—Sarawak (and Penang).

Black, head with two whitish lines in front, vertex and anterior border of the prothorax jet-black, rest of the prothorax, a large median patch common to both elytra, and a spot at the apex of

[page] 381

each, white (or ochraceous); body beneath dusky, the sides white; legs testaceous; antennæ brownish.

Length 5—6 lines.

Differs from the last species principally in the patches on the elytra, and the absence of stripes. In a Penang specimen white replaces the pure ochraceous-yellow of the Sarawak examples.

Glenea luctuosa.

G. capite atro; prothorace apice excepto, elytrisque plaga submedia communi, albis (♂).

Hab.—Aru, Salwatty.

Head black, face and cheeks whitish; prothorax white, the apical border black; scutellum small, black; elytra short, black, a broad band or patch, rather behind the middle, white; body beneath and legs reddish-luteous, sides of the sterna white; antennæ brown.

Length 4 lines.

This species wants the apical white spots of the last, and is, moreover, distinguished by the shortness of the elytra, which are also much broader at the apex. I believe it is the Glenea luctuosa of Dejean's Catalogue.

Glenea funerula.

Stibara funerula, J. Thomson, Arch. Ent. i. 141.

G. vertice prothoraceque atris, hoc postice albo; elytris atris, plagis duabus ad suturam fere connexis, maculisque duabus apicalibus, albis (♂,♀).

Hab.—Singapore (and India).

Head black on the vertex, becoming paler in front, the cheeks ashy-white; prothorax jet-black anteriorly, pure white posteriorly; acutellum and elytra black, a large squarish transverse patch behind the middle of each elytron, nearly meeting at the suture, and a small spot on each apex, white; body beneath with a thin whitish pubescence, the sides spotted with black; antennæ black; femora brownish-luteous, tibiæ and tarsi dusky with a whitish pubescence.

Length 6 lines.

My Indian specimen is very much shorter than those obtained by Mr. Wallace at Singapore.

Glenea fatalis.

G. supra nigra, opaca, infra et lateribus declivibus elytrorum cinereis, apicibus fulvo-maculatis; femoribus tibiisque luteis, tarsis cinereis (♂, ♀).

Hab.—Sarawak.

Upper parts dull brownish-black, the apex of each elytron with a squarish fulvous patch; cheeks, sides of the prothorax, the declivous portion of the elytra, and body beneath ashy; femora and tibiæ luteous; tarsi covered with an ashy pile; antennæ black.

Length 6 lines.

Very distinct in its coloration, but in general habit resembles more nearly the foregoing species than any other.

Glenea Calypso. (Pl. XVII. fig. 3.)

G. nigro-tomentosa, sulphureo-figurata et lineata. (♀).

Hab.—Sarawak.

Covered above with a dense black tomentum and varied with sulphur-yellow lines; head nearly glabrous, the eyes entirely surrounded with a yellow pubescent border, except at the base, a yellow line also bordering the epistome; prothorax edged on all sides with yellow; scutellum yellow; base of the elytra, and a stripe along the deflected side, an annular somewhat hexagonal figure, connected along the suture, on the anterior part of the disk, and posteriorly another series of lines uniting at the suture and forming an X-like figure, pale yellow; body beneath with a sulphur-yellow pubescence, with luteous-glabrous spots on the sides and middle of each abdominal segment; legs black, trochanters and bases of the femora luteous; antennæ black.

Length 8 lines.

The prothorax of this fine and very distinct species, of which I possess but one specimen, is rather more convex and rounded at the sides than in the generality of the Gleneæ.

Glenea anticepunctata.

Stibara anticepunctata, J. Thomson, Arch. Ent. i. 142.

[page] 383

cula laterali ante medium, alteraque quadrata præ-apicali ochraceis, cæteris humerisque atris (♀).

Hab.—Singapore.

Head and prothorax jet-black, stripe on the vertex, continuous with another on the prothorax, ochraceous; scutellum semicircular, ochraceous; elytra with a large fawn-coloured patch anteriorly, bordered at the shoulders with black, and having a triangular ochraceous spot at the side, posteriorly, but before the middle, jet-black, except a quadrangular præ-apical ochraceous spot not quite extending to the suture; body beneath, sides of the prothorax, coxæ, and anterior and intermediate tarsi, covered with a dark smoky-grey pubescence, rest of the legs yellowish-testaceous; antennæ black.

Length 6—7 lines.

The punctures on the elytra are confined to the comparatively small space occupied by the fawn-coloured patch, and this has apparently suggested the specific name.

Glenea lanthe.

G. capite prothoraceque supra atris; elytris antice cervinis, macula laterali ante medium, alteraque quadrata præ-apicali ochraceis, humeris scutelloque atris (♂).

Hab.—Singapore.

Possibly the male of the last, but the head and prothorax are without the bright ochraceous stripe, and the scutellum is black, except a slight border of fawn-colour at the apex; the narrower outline in this case is precisely what might be looked for in the male; the prothoracic stripe in G. anticepunctata, however, is composed of hairs longer than the rest, set transversely, the extremities of which form a narrow elevated line along the middle, a character which is quite opposed to the uniform, somewhat tomentose, pubescence of the example before me.

Length 5½ lines.

Glenea udetera.

Stibara oudetera, J. Thomson, Arch. Ent. i. 143.

G. capite, vertice ochraceo excepto, prothoraceque atris, hoc postice et lateraliter albis; scutello cervino; elytris dimidio basali cervinis, fascia interrupta post medium maculaque quadrata præ-apicali ochraceis, cæteris fuscis.

Hab.—Sarawak.

Head and prothorax jet-black, the former with its vertex

[page] 384

ochraceous, the latter with a pale citron-yellow band along its base, expanding and entirely covering its sides; scutellum subtriangular, with its apex rounded, fawn-coloured; elytra with their basal half fawn-coloured, bordered behind with a narrow interrupted ochraceous band, the rest dark brown, except a large quadrangular præ-apical ochraceous spot, not extending to the suture; body beneath pale reddish-brown, sides of the four basal abdominal segments pale yellowish; legs, including the coxæ, yellowish-testaceous; antennæ dark fawn-coloured, the basal joint brown.

Length 6—7 lines.

Glenea Egeria.

G. capite prothoraceque supra atris, hoc postice et lateraliter albis; scutello elytrisque dimidio basali cervinis, fascia interrupta post medium maculaque quadrata præ-apicali ochraceis, cæteris nigris (♂).

Hab.—Singapore.

Perhaps only a variety of the last, which it nearly resembles in colour, but the head is entirely black; the body, and especially the prothorax, are proportionally narrower, and the eyes considerably more approximate above.

Length 4½ lines.

Glenea Aspasia. (Pl. XVII. fig. 2.)

G. robusta, capite atro, genis lineaque antica oculorum albescentibus; prothorace atro, postice et lateraliter albescente; scutello cervino; elytris dimidio basali cervinis, fascia ante medium maculaque communi præ-apicali ochraceis (♀).

Hab.—Sarawak.

Resembles G. udetera, but much more robust; no spot on the vertex, the cheeks whitish, the elytral ochraceous band before the middle, the præ-apical spot triangular and forming with its fellow a transverse somewhat lozenge-shaped patch, not extending to the carina as in the two preceding species, the puncturation on the shoulders much coarser, the outer apical spine very short, and the whitish pubescence beneath more interrupted and covering part of the last abdominal segment; the antennæ dark brown.

Length 7 lines.

Glenea Melia.

G. fusca, lineis maculisque rufo-ochraceis; infra castaneo-fusca, metasterno niveo (♂, ♀).

Hab.—Sarawak.

Dark brown, with reddish-ochraceous lines and spots; head with two lines in front extending to the vertex, the eyes posteriorly bordered with ochraceous; prothorax with three narrow lines on the disk, and one on each side; scutellum entirely brown; elytra with from eight to ten small spots on each, in one specimen a short line between the shoulder and scutellum; body beneath nearly uniformly dark chesnut-brown, the metasternum and its episterna covered with a dense snowy-white pubescence, except in the middle; legs brownish, tarsi with a thin whitish pile; antennæ brown.

Length 7 lines.

The strictly limited white patch on each side differentiates this species from every other in the collection, except G. ochraceovittata, from which it may be known, inter alia, by its spotted elytra.

Glenea numerifera.

Hab.—Sumatra (and Malacca).

Near G. extensa, but the elytra coarsely punctured as in G. acuta; from the former it differs in the very short or rather interrupted humeral stripe, and the transverse bar below the middle, which unites with the posterior portion of that stripe to form a mark exactly resembling the figure 7, which is of course reversed on the other side; the apex of the third joint is indistinctly blotched with whitish.

Glenea Sophronia.

G. nigra, vittis plumbeis indistinctis, vertice nullis, prothorace tribus fere obsoletis, elytris disco quinque, vitta basali integra (♀).

Hab.—Dorey.

Black, with very indistinct ashy or leaden stripes, none on the vertex, those on the elytra nearly obsolete, the outer one broad and irregular; scutellum transverse, emarginate at the apex; elytra with five very pale stripes on the disk, the basal intermediate entire, the ashy colour more distinct on the apices; body beneath and legs with a thin ashy pubescence; antennæ dark brown.

Length 4½ lines.

In its indefinite coloration, giving a dull leaden hue to the upper surface, this species resembles the last, but, inter alia, the scutellum is broadly emarginate at the apex, and the external spine of the apices of the elytra is reduced to little more than a mere point.

Hab.—Batchian, Singapore.

Black, striped and spotted with pale ashy; cheeks whitish, two stripes on the vertex, five on the prothorax and five on the elytra, including the sutural, the humeral stripe extending from the shoulder to within one-fourth of the apex, the intermediate commencing from a broad spot at the base and extending to above a third of the length of the elytron, a spot in the middle and another between the humeral stripe and the apex; body beneath ashy, a broad white stripe on the sides of the sterna and abdomen; legs and antennæ black.

Length 5—6 lines.

Related to G. basalis according to M. Thomson, but it seems to me much more nearly allied to the following, from which it differs principally in the light brownish colour of the elytra, and in the four spots being nearer the base.

Hab.—Sarawak, Sumatra.

Lightish brown, the prothorax darker, striped and spotted with pale ochreous; cheeks and face whitish, vertex with two, prothorax with three stripes; scutellum entirely ochraceous; elytra with five indistinct stripes, the humeral almost obsolete, the basal short or forming an oblong spot, one spot just before the middle, the other a little behind it and remote from the apex; body beneath white, gradually shading off into pale ferruginous; antennæ dark brown; legs pale ferruginous.

Length 5—6 lines.

Glenea collaris, Pasc., to which M. Thomson refers, is quite different from the insect standing under that name in his collection.

Glenea Myrsia.

G. fusca, sordide griseo-vittata; elytris breviusculis, quinquevittatis, vitta intermedia abbreviata; corpore infra lateraliter albo-vittato (♀).

Hab.—Amboyna.

Dusky brown, or blackish, with greyish stripes; the vertex with two stripes, front and cheeks greyish-white; prothorax longer than broad, with three stripes; scutellum narrow, rounded behind, greyish; elytra short, with five stripes, the intermediate between the base and middle, the humeral not reaching to the apex; body beneath dark reddish-brown, the sides throughout with a nearly pure white stripe; legs dusky testaceous; antennæ brownish.

Length 5 lines.

Remarkable for its comparatively long prothorax and short elytra; in the central stripe and general appearance it resembles the next.

The preceding members of this section are rather short and robust; but this and the rest of the section as far as G. Latania are more slender; from that point they are again stouter; there is, however, an obvious connexion between them which forbids any division. G. regularis, Newm., (G. Kraatzii, Thoms.), be-

longs to this section, and is intermediate between the slender and the stouter forms.

Black, with pale dull-greenish stripes; two stripes on the vertex, lower lobe of the eye also margined with green; prothorax with three stripes; scutellum sub-semicircular, green in the middle; elytra with five stripes, the sutural indistinct, the intermediate basal stripe extending to beyond the middle of the elytron, the humeral stripe approaching the apex; body beneath reddish-brown, with the sides of the sterna and abdomen clear blueish-green; legs brown, tarsi pale blueish; antennæ black, scape dark ferruginous.

Length 5 lines.

A dingy species, with the disposition of the colours much the same as in G. venusta, but without the two spots on the elytra, and the intermediate basal stripe is much longer.

Glenea Acasta.

Hab.—Tondano.

Black, with ochraceous stripes; head black above, a narrow stripe of the same colour between the eyes, cheeks and front, except the black stripe, ochraceous, two stripes between the eyes united on the vertex; prothorax with three stripes; scutellum semicircular, ochraceous; elytra with five stripes, the sutural and two on each, the intermediate basal very short and oblique, the humeral extending from the shoulder to very near the apex, none on the declivous portion; body beneath black, with greenish metallic patches, principally at the sides of the sterna and abdomen; femora ferruginous, tibiæ brownish, tarsi with a blueish pubescence; antennæ black, the apex of the third joint white.

Hab.—Singapore.

Black, with narrow cobalt-blue stripes; head blueish-white in front and on the cheeks, the blue predominating in two narrow stripes between the eyes but not extending to the hind-head; prothorax with a narrow median stripe, its sides blueish-white, the basal margin blue; scutellum blue at the apex; elytra with five stripes, the sutural terminating in a broad band at the apex, the two on each side somewhat indistinct, the humeral ending in a short transverse bar; body beneath pale ashy, a glossy black spot on each side of the metasternum, and a smaller one on the first abdominal segment on each side; femora brownish-fulvous at the base, gradually passing into ashy and pale cobalt, the latter especially on the tarsi; antennæ black, the first three joints blueish.

Length 4½—5½ lines.

In this rather slender species the stripes between the eyes do not ascend to the vertex, but cease abruptly between the upper lobes of the eyes; the humeral stripe ends in a short transverse bar. G. Colobothoides, Thoms., is allied to this.

[page] 393

Head and prothorax above blackish, the former with two, the latter with a single median stripe, front and cheeks ashy; scutellum semicircular, blackish, the apex white; elytra pale yellowish-brown, with five very indistinct stripes; body beneath and sides of the prothorax uniformly ashy; legs and antennæ yellowish-testaceous, the latter with the two basal joints blackish.

Length 5½ lines.

Resembles the last, but paler, with the two lateral prothoracic stripes obsolete, and the body beneath uniformly ashy; the punctuation of the elytra is less marked; in both the external apical spine is strongly produced.

Glenea Anona.

G. capite prothoraceque nigris, elytris fuscis, supra pallide ochraceo-vittatis; vertice vittis duabus, prothorace tribus, elytris quinque; horum apicibus singulis macula nivea ornatis (♂).

Hab.—Singapore.

Head and prothorax black, the eye bordered with white, two narrow pale ochraceous lines on the vertex; prothorax with a narrow pale ochraceous median line; scutellum semicircular, ochraceous; elytra dark brown, the suture and humeral stripe ochraceous, a spot near the apex at the base of the slender exterior mucro white; body beneath chesnut-red, with a pure white stripe on the sides, and another on the metasternum; legs reddish-testaceous, the four anterior tarsi brown, the lower half of the posterior tibiæ and their tarsi white; antennæ dark brown, covered with a whitish pubescence, the last four joints white.

Length 5 lines.

This has a slightly broader prothorax and more trigonate elytra than some of the preceding, to which its coloration allies it.

Glenea Alysson.

G. capite prothoraceque fuscis, hoc et vertice in medio vitta ochracea; elytris brunneis, extus infuscatis, apicibus singulis macula nivea ornatis.

Hab.—Singapore (and Penang).

Head and prothorax dark brown, a narrow white line bordering the eye and cheeks, the vertex and prothorax with a broad

[page] 394

ochraceous stripe; cheeks, stripe on the side of the prothorax, and all the under parts, pale ashy; scutellum nearly semicircular, ochraceous; elytra with the disk entirely pale brown, blackish at the sides and apex, the latter with a small snowy spot at the base of the strongly marked exterior mucro; legs reddish-testaceous, the lower half of the posterior tibiæ and their tarsi white; antennæ black, the last four joints white.

Length 5–6 lines.

This may possibly be G. lineatocollis, Thomson, Ess. &c., p. 52, a species I do not recollect seeing in his collection, but from his description, which appears to have been made from a specimen with obsoletely striped elytra, there seem to be no spots on the apices; indeed it is expressly stated that they are not spotted; and no mention is made of the white terminal joints of the antennæ.

Glenea Latania.

G. læte ochraceo-lineata; capite prothoraceque atris, hoc supra tri- vertice fronteque bi-vittatis; elytris singulis trivittatis, vitta intermedia sub-basali, brevissima, externa cum fascia basali juncta; antennis apice articuli tertii albido (♀).

Hab.—Menado.

Head and prothorax black, elytra reddish-brown, with very clear ochraceous stripes; head with the cheeks, border of the epistome and two stripes in front extending to the vertex; prothorax with three stripes, its sides above the coxæ pale ochraceous; stripe on the scutellum and along the suture also bordering the apices, a very short sub-basal stripe, the outer or humeral stripe connected with a band close to the base; body beneath chesnutred, its sides from the cheeks to the anus pale ochraceous; legs fulvous; antennæ brown, the apex of the third joint yellowish white.

Length 6 lines.

A very pretty species, noticeable for the way in which the humeral stripe is reflected at the base of the elytra, the branches being prevented from meeting by the broad scutellum.

Glenea Jubæa.

Hab.—Sarawak (and Penang).

Reddish-brown, with fulvous stripes; two stripes on the vertex, and five on the prothorax; scutellum fulvous in the middle; elytra with three stripes on each, the sutural also bordering the apex, the intermediate basal and very short, and the humeral extending from the shoulder to near the apex; body beneath with a pale-ochreous pile, divided by three glabrous stripes; legs dark testaceous; antennæ entirely dark brown.

Length 5 lines.

Somewhat like the last in the distribution of the stripes, but the colouring duller, and without the basal band; the antennæ unicolorous, &c. Thi s is possibly identical with G. mima, Thomson.

Glenea albolineata.

J. Thomson, Ess. &c., p. 51.

G. nigro-violacea, nitida; prothorace nigro, postice constricto; elytris singulis vittis tribus (suturali inclusa) sordide albescentibus (♀).

Hab.—Batchian, Bouru.

Violet-black, shining; head black, face, cheeks, two lines on vertex, and one behind each eye, dull white; prothorax constricted posteriorly, and narrower than the apex, black, three dull white stripes on the disk, and one on each side; scutellum transverse, truncate behind; elytra rather short, the violet assuming a dingy tint in certain lights, the sutural, a shorter intermediate, and the outer stripe, dull whitish; another, almost obsolete, stripe on the deflected side; body beneath covered with a delicate white pubescence; legs greyish; antennæ black.

Length 6 lines.

Glenea lugubris.

G. atra, opaca; prothorace postice vix constricto; elytris singulis vittis duabus (suturali inclusa) et macula basali albis; spina exteriore apicali robusta (♂).

Hab.—Ceram.

Jet-black, opake; face, cheeks, two lines on the vertex, and one

[page] 396

behind each eye pure white; prothorax scarcely or very slightly constricted posteriorly, and broader than the apex, three white stripes on the disk, and one an each side; scutellum semicircular, white; elytra elongate, the sutural and outer stripe white, between the two at the base a short triangular spot, a well marked stripe on the deflected side; body beneath covered with a chalky-white pubescence, a black glabrous spot on each of the abdominal segments at the sides; legs with a thin ashy pile; antennæ black.

Length 6½ lines.

In this species the anal processes are rather long, and slightly divergent. G. versuta, Newm., differs principally in the antennæ having the third joint white at the apex.

Glenea Attalea.

G. atra, squamulis opacis dense vestita; prothorace vix constricto; elytris breviusculis, supra albo-vittatis, spina exteriore apicali parva (♀).

Hab.—Ceram.

Perhaps only the female of the preceding; it is remarkable, however, for the opake dense squamiform pubescence of the black portion, and for the whiter and longer pubescence of the stripes; the outer apical spine is also smaller, and the general outline is much more robust, but scarcely exceeding what might be expected in the female.

Length 7 lines.

Glenea cæruleata.

G. cærulea, nitida, subtilissime pubescens; prothorace nigro, postice constricto; elytris supra griseo-quinque-vittatis, vitta intermedia interrupta (♂, ♀).

Hab.—Ceram.

The variation in the extent and distinctness of the white stripes in the two individuals before me shows the uncertainty of this class of their characters; all that remains, therefore, to differentiate this species is the blue colour of the elytra, changing like shot silk in certain lights, and the pale ashy stripes; these give the insect a primâ facie distinctness totally different from any other in this section.

Glenea Hyphæne.

G. ochraceo-lineata, capite prothoraceque fuscis, hoc supra triet vertice bi-vittatis, fronte in medio fusca; elytris pallide quinque-vittatis.

Hab.—Morty.

Head dark brown, with the cheeks, border round the lower lobe of the eye, two stripes on the vertex and one behind the eye ochraceous, the middle of the face brown; prothorax blackish-brown, a broad central, a narrower lateral stripe, beneath which is another very broad stripe, ochraceous; scutellum transverse, ochraceous; elytra pale brownish, each with three indistinct ochraceous lines, including the sutural lines which extend to and cross the apex to the exterior mucro, the second stripe extends rom the base to a little beyond the middle, the third lies midway between the second and the carina, and extends nearly to the apex; body beneath and legs reddish-yellow, sides of the sterna and abdomen ochraceous; antennæ blackish.

Length 6 lines.

Glenea Corypha.

G. ochraceo-lineata, capite prothoraceque fuscis, hoc supra uniet vertice bi-vittatis, fronte ochracea.

Hab.—Amboyna.

Perhaps only a variety of the last, from which it principally differs in the face being entirely ochraceous, in having only the central stripe on the disk of the prothorax, and in the lines on the elytra being more deeply coloured.

Glenea interrupta.

G. cyaneo-chalybeata, nigro-tomentosa, rufo-vittata; prothorace tri- elytrisque quinque-vittatis, his vitta intermedia basali abbreviata, postea et ante medium macula rotundata, vitta suturali postice obsoleta, macula apicali ampla.

Hab.—Amboyna (and Batchian).

Dark chalybeate-blue, closely covered with a short black tomentum striped and spotted with reddish; cheeks and front whitish, two stripes on the vertex and three on the prothorax, the sides whitish; elytra with five stripes, the sutural gradually disappearing posteriorly and the intermediate short, followed by a

[page] 398

round spot, another large spot at the apex, humeral stripe nearly extending to the apical spot; body beneath with a close white pubescence; legs more thinly pubescent; antennæ black.

Length 6—8 lines.

The general colour seems to be black, but with a lens the derm is seen to be of a dark chalybeate-blue.

Glenea mathematica.

G. capite prothoraceque nigris, hoc angusto, lateribus fere parallelis, in medio vitta ochracea; vertice vittis duabus; elytris fuscis, vitta suturali ad apicem haud currente, vitta humerali maculaque apicali, ochraceis (♂).

Hab.—Java.

Head and prothorax black, the latter narrow with the sides nearly parallel; two stripes on the vertex and two on the prothorax pure ochraceous; scutellum rather narrow, rounded behind, ochraceous; elytra dark reddish-brown, a narrow sutural stripe not extending to the apex, and a humeral stripe nearly united to a large oblong apical spot, ochraceous; body beneath brown, the sides striped with white; legs luteous; antennæ reddish-brown.

Length 5 lines.

In colour and form recalling G. Anona, but obviously more nearly allied to the following.

Glenea algebraica.

Stibara algebraica, J. Thomson, Arch. Ent. i. 144.

G. fusca, vitta lata ochracea a vertice ad apices elytrorum, vitta humerali nulla (♂, ♀).

Hab.—Sarawak, Singapore.

Dark brown, a broad well-marked ochraceous stripe extending from the vertex to the apices of the elytra and terminating at the outer spine, the front entirely whitish, or whitish with a large central blackish spot, the vertical stripe either fading away in front or well limited; scutellum semicircular; body beneath uniformly white, with the middle of the abdomen generally luteous; legs testaceous, tarsi whitish; antennæ dark brown.

Length 5—6 lines.

The side of the prothorax is sometimes divided by a white stripe.

Glenea analytica.

G. fusca, vitta ochracea a vertice ad apices elytrorum, vitta humerali angustata (♂).

Hab.—Sarawak.

Closely allied to the last, but the vertical stripe dividing between the eyes and embracing a large black patch; the prothorax larger and more constricted posteriorly; the scutellum less rounded and longer; there is also a narrow humeral stripe as in G. mathematica, which does not, however, extend to the apex, and the sutural stripe is narrower and of uniform breadth, spreading out however at the base.

Length 6 lines.

Glenea eclectica.

G. fusca, vitta ochracea a vertice ad apices elytrorum, vitta etiam postica, apicibus oblique emarginatis; scutello semicirculari.

Hab.—Sarawak.

This bears a close resemblance to G. algebraica, but it is very considerably shorter, the elytra flatter posteriorly and their apices oblique and less deeply emarginate, the outer spine is nearly obsolete, and there is no trace of the angles formed by the deflected sides; the stripe on the elytra spreads out at the base so as to touch the shoulders, and the legs are darker: there is only one example; how far, therefore, some of these characters may be permanent must be left for future observation.

Length 4 lines.

Glenea discoidalis.

Dark brown, stripe on the vertex and prothorax ochraceous; cheeks and front ashy; scutellum sub-scutiform, ochraceous; elytra with the disk almost entirely pale yellowish-brown, the sides dark brown and nearly glabrous, the apex of each with a strong outer spine; body beneath ashy; legs fulvous; antennæ brownish, gradually becoming white towards the apex.

Length 4 lines.

This species has the elytra much more strongly punctured than the last, and the angle formed by the deflected side is very prominent.
