I. Phytophaga Malayana; a Revision of the Phytophagous Beetles of the Malay Archipelago, with Descriptions of the New Species collected by Mr. A. R. WALLACE. By JOSEPH S. BALY, F.L.S., M.R.C.S.
SECTION I.
APOSTASICERA:
INCLUDING
The Families SAGRIDÆ, DONACIIDÆ, CRIOCERIDÆ, MEGALOPIDÆ, CLYTHRIDÆ, CHLAMYDÆ, CRYPTOCEPHALIDÆ, EUMOLPIDÆ, and CHRYSOMELIDÆ.
[It was intended that Mr. Baly's Revision of the Malayan Phytophaga should be published in a continuous form, so that the whole might eventually be bound up together, as a companion volume to the Longicornia Malayana of Mr. Pascoe. The first 76 pages were issued in June, 1865, and it was then announced
( 2 )
that Mr. Baly's Introductory Remarks on the Group were reserved until the Species were described. The delay in obtaining from the Author a second instalment of descriptions has compelled the Council to abandon the idea of devoting an entire volume of the "Transactions" to this special work.—Sec. Ent. Soc., August, 1867.]

Hab. Java, Flores; also Cambodia, whence it has been sent by the late Mons. Mouhot, in great abundance.
This fine species is most closely allied to S. speciosa, Lac.: it agrees so completely in nearly all its characters with that insect that a detailed description would be almost useless. I shall therefore confine myself to the points of difference between the two insects.
In S. mutabilis ♂ the antennæ are equally long, but stouter; the thorax is usually (but not always) slightly broader; the elytra are much broader at their base, the humeral callus being more prominent, and causing the base of the elytra to appear more abruptly truncate; they are shorter in proportion to their basal breadth, and at the same time more quickly narrowed from base to apex, thus being less parallel and more regularly wedge-shaped; they are less deeply depressed transversely below the basilar space, their surface is more finely punctured and opake. The hinder thighs are shorter, thicker, and less attenuated towards their apex; viewed laterally, they are suddenly thickened at their base, and then gradually increase in width to beyond their middle; in S. speciosa they increase more gradually at first, but remain for some distance in the middle at nearly the same width; viewed from above, the outer edge in S. mutabilis is more regularly curved, the thickest portion of the femur being about or just beyond the middle; in S. speciosa, on the other hand, the thigh is more attenuated from its middle to its apex, the thickest part being rather before than at the middle itself. In the female the elytra are oblong-ovate, and not narrowed from base to apex as in the male; but I do not know any characters by which the ⁀ can be separated with certainty from the same sex of S. speciosa, S. Druryi, and other allied species.

Hab. Borneo; collected by the late Madame Pfeiffer.
Robust, ovate, resembling S. quadraticollis in form, but rather shorter and thicker than that insect, bright metallic green, with metallic blue reflexions, subnitidous, outer half of antennæ black, opake. Head finely punctured; antennæ robust, two-thirds the length of the body, six basal joints shining metallic green. Thorax subquadrate, almost transverse across the anterior angles, the latter moderately prominent, anterior margin very slightly produced; upper surface subopake, impressed near the basal margin with a shallow fovea; sparingly covered near the base by a few very minute punctures, only visible under a lens. Scutellum semiovate, its base deeply excavated. Elytra shorter, ovate, truncate at the base, their apex subacutely rounded; above very convex, moderately impressed within the shoulders, the latter somewhat prominent; basilar space indistinctly elevated, bounded beneath by a nearly obsolete transverse depression; surface covered with fine irregularly confluent grooved lines, more crowded towards the apex, where their interstices are raised, and form irregular crenulations; on each elytron are six or seven double rows of punctures, visible only here and there, principally on the anterior half of the surface, being entirely obliterated for the remainder of their course; on the outer disc, just before its middle, is a small smooth spot, shining blue-green.
Male.—Posterior thighs strongly incrassate, extending beyond the elytra for nearly half their length, their outer surface very convex, the thickest portion of the thigh being across its middle; lower edge deeply notched at the apex and armed with two stout teeth, the anterior larger and situated immediately in front, the other placed just at the posterior angle of the notch, the inner edge of which is clothed with fulvous hairs; hinder tibiæ curved at the base, thence nearly straight to the apex, the middle portion slightly flexuose; apex strongly mucronate, armed on either side with a stout tooth, the outer one large and slightly curved, the inner one very short; inner edge notched at the base, deeply grooved and sparingly clothed with pale pubescence; basal segment of abdomen flattened, remotely punctured, very sparingly dotted with a few fulvous hairs.
This fine insect bears a very much stronger resemblance to S. superba and quadraticollis than to S. Druryi and its allies, with which insects, from the possession of a second tooth at the apex of the lower edge of its hinder femora, it must be placed; the position however of this tooth is very different—instead of being situated in the notch itself, as in the above-named species, it is placed at its posterior angle.

Long. 3—3½ lin.
Hab. Tringanee, Java? also Ceylon and India.
Head very finely rugose-punctate, face impressed with a longitudinal groove which runs backwards nearly to the neck;
antennæ half the length of the body, obscure rufous, basal joints obscure æneous, the remaining joints more or less stained at their apex with black; second and third joints nearly equal, each one half shorter than the fourth. Thorax rather broader than long, sides nearly straight and parallel, slightly constricted at the base, anterior angles distinct, rectangular, not produced, the angle itself indicated by an obtuse tubercle, from the centre of which springs a long single hair; hinder angles slightly produced, obtuse, curved slightly upwards; upper surface transversely excavated at the base, medial line impressed by a distinct longitudinal groove, which is broader and deeper towards its base; whole surface of disc covered with very fine transverse rugæ. Scutellum triangular, acute, covered with fine adpressed pubescence. Elytra much broader at their base than the thorax, sides straight and parallel along their anterior half, thence obliquely narrowed to the apex, the latter truncate; upper surface flattened along the suture, lightly depressed transversely below the basilar space, deeply punctate-striate, interspaces thickened and slightly raised, nitidous, obsoletely transverse strigose.
This species must be placed close to D. Delesserti, to which it is very closely allied, if not indeed a variety of that insect; it differs in having the anterior angle of the thorax indicated by a small but distinct tubercle, and in the longitudinal groove on the disc extending nearly from base to apex. I possess specimens from Ceylon; from the continent of India, collected by Mr. Brettingham; and from Tringanee, sent to this country by Count de Castelnau.

Hab. Singapore.
Head deeply constricted behind the eyes, the latter prominent, deeply notched; face triangular; antennæ filiform, nearly three-fourths the length of the body. Thorax scarcely broader than long; its sides moderately constricted; above smooth, a longitudinal space down the middle impressed with a number of very fine punctures; just in front of the base is a single distinct fovea; on either side, running obliquely inwards and backwards from the lateral constriction, is a short transverse groove. Scutellum glabrous, elongate-trigonate, its apex truncate. Elytra much broader than the thorax, oblong, indistinctly impressed transversely below the basilar space, finely but distinctly punctate-striate. Abdomen clothed with coarse adpressed whitish hairs. Thighs moderately thickened, the hinder pair rather thicker than the others, extending to the apex of the third abdominal segment.
This insect, which has at first sight very much the aspect of the pale variety of Crioceris impressa, must be placed close to L. Goryi.

My specimens of this insect differ somewhat from the one from Bengal (which I have not seen) described in Lacordaire's work; mine have the abdomen almost, in one case, entirely black—in one specimen, also, the anterior legs are piceous; in all, the anterior half of the elytra is distinctly rugulose, and the basilar space is bounded beneath by a transverse depression; this latter character is not mentioned by Lacordaire; I do not think these differences are sufficient to constitute a distinct species; like many insects with a wide geographical range it is probably variable both in sculpture and coloration.

Hab. Aru Islands, New Guinea.
This and the two preceding species agree so completely in general colour, form, and sculpture, that it will be only necessary to give the points of difference:—
In P. Papuana the antennæ are entirely rufo-testaceous; the colour of the darker portion of the elytra, which is violaceous, varies greatly in extent, sometimes covering only the hinder two-thirds of the elytra, in other specimens extending over the whole surface, leaving only a narrow space at the basal margin; the hinder thigh in the ♂ of the same species has a strong conical spine.
In L. Boisduvalii the outer half of the antennæ is black; the colour on the elytra is bright cyaneous instead of violaceous, and less variable in extent, occupying usually rather more than two-thirds of their surface; and the femoral spine of the ♂, though equally long, is less robust and slightly curved at its apex.
The ♂ of L. connectens may be known from either of the other two species by the much shorter spine on the hinder femora;
both sexes may be readily distinguished by the nigro-cæruleous tint of the darker portion of the elytra (which varies very little in extent), by the pale upper lip, and by the black markings on the upper surface of the joints of the antennæ; these markings vary very greatly, in some specimens being confined to mere patches near the apex of each joint, in others covering the whole of the upper surface, leaving only a pale line beneath.
12. Lema atriceps, n. sp.

Head constricted behind the eyes; face triangular, epistome triangular, front smooth and shining, finely punctured, impressed behind with a short longitudinal fossa; antennæ filiform, three-fourths the length of the body, fifth joint shorter than the two preceding united; eyes notched. Thorax very similar in form to that of L. Papuana, deeply strangulate just behind the middle, surface smooth, remotely impressed with very fine punctures. Elytra much broader than the thorax, nearly four times its length; sides parallel, their apex regularly rounded, above convex, impressed within the humeral callus, each elytron with ten rows of distinct punctures, visible to the apex, the row nearest the suture sulcate in front, interspaces smooth, slightly raised near the apex of the elytron. Body beneath smooth and shining, abdomen nearly glabrous. Hinder thighs in the male equal to the abdomen in length; in the female not extending beyond the first three segments, much less thickened, and unarmed.
The absence of the transverse depression on the elytra, the larger size and different coloration, will at first sight separate this species from L. Papuana and its near neighbours.
The six species from L. Papuana to L. militaris inclusive form
a group belonging exclusively to the Malayan fauna. Until the expedition of Mr. Wallace, L. Papuana was the only one known to us.

Thorax subquadrate; sides deeply constricted just behind their middle; above subcylindrical, deeply impressed in front of the base by a transverse groove, either end of which terminates in the lateral constriction; surface smooth and shining, impunctate, bright rufo-fulvous, a broad vitta down the centre, which gradually increases in width behind, and is abbreviated at the transverse groove, black. Scutellum shining black, its apex truncate. Elytra much broader than the thorax, oblong, convex, indistinctly depressed transversely below the base; shining black, whole surface irregularly covered with large deep variolose punctures, more crowded and confluent towards the sides; interspaces smooth and shining, much thickened and elevated, and forming towards the sides irregular reticulations.

Head deeply constricted behind the eyes, the latter very prominent, angularly notched; face triangular, forehead depressed, impressed in the middle with a single fovea; antennæ slender, nearly equal to the body in length. Thorax distinctly broader than long, sides very deeply constricted about their middle, upper surface smooth, finely but subremotely punctured, deeply impressed a short distance behind the lateral constriction by a broad transverse sulcation, which extends at either side into the constriction itself; disc gibbous, bounded on either side by a deeply impressed and slightly sinuate longitudinal groove, which, commencing at the base of the thorax, intersects the transverse sulcation, and runs almost directly upwards and slightly outwards nearly to the apical margin; the surface of gibbosity finely but subremotely punctured, impressed longitudinally with a fine grooved line; the space bounded by the transverse groove in front, posteriorly by the base of the thorax, and laterally by the longitudinal sulci, is flattened and depressed. Scutellum trigonate, its apex broadly truncate, extreme apex black. Elytra much broader than the thorax, parallel, somewhat flattened along the back, closely covered with elevated tubercles, the spaces between which are deeply impressed with large round punctures; each elytron in addition is furnished with seven much larger tubercles, greatly resembling those on the surface of a Chlamys: they are placed as follows—the first on the basal margin transverse, less curved than the others and obtuse; the second just within the lower end of the humeral callus; the third immediately below the basilar space, at some little distance from the suture; the fourth just below the middle, halfway between the suture and outer margin; the fifth and sixth placed obliquely nearly midway between the middle and apex, and the seventh subapical, a little distance from the lateral border; the last six are all conical and strongly raised.

Closely resembling the last species, much smaller, the larger tubercles on the surface of the elytra being as broad, or even broader, at their base, but much less strongly elevated; the second and third are also rather differently placed on the surface, the first of them being halfway between the humeral callus and the suture, and the other close to the suture itself; the fifth and sixth have their apices rounded and not conical; the seventh large tubercle is absent. The elytra are closely covered with small tuberosities, to the almost entire exclusion of the puncturing; those near the hinder half of the lateral margin are larger and more distinct than those elsewhere and form a row of rounded protuberances. Head very similar to that of L. monstrosa, the antennæ somewhat shorter. Thorax finely but subremotely punctured; centre of disc convex, slightly gibbous, longitudinal sulci obsolete in front of the transverse groove, being visible only at the base in the form of two oblique impressions.

Papuana. Scutellum subquadrate, its apex truncate. Elytra much broader than the thorax, nearly three times its length, parallel, transverse impression below the basilar space broad and deep but ill defined; interspaces between the rows of punctures, when viewed under a lens, finely but not closely punctured. Hinder thighs slightly thicker than the others, extending nearly to the apex of the fourth abdominal segment; unguiculi of all the legs black.

Head trigonate, forehead impressed with a faint longitudinal fovea; eyes deeply notched; antennæ filiform, moderately robust,
two-thirds the length of the body, third and fourth joints equal, each nearly twice the length of the second. Thorax distinctly longer than broad; upper surface smooth, nitidous, a longitudinal space on the middle disc impressed with minute punctures. Scutellum triangular, its apex truncate, piceous. Elytra much broader than the thorax, parallel, cylindrical, punctate-striate, punctures strongly impressed at the base, fine towards the apex of the elytron, interspaces plane in front, convex towards their apex. Body beneath nearly glabrous. Unguiculi black. Mesosternum elongate, its apex obtuse, more or less deeply emarginate.
This species is in my opinion undoubtedly the L. cyanipennis of Fabricius, the insect described by M. Lacordaire under that name being a closely allied but quite distinct species. Fabricius gives Sumatra as the locality of his L. cyanipennis, whilst M. Lacordaire's insect (for which I would propose the name of L. Lacordairii) is a native of Continental India. The true cyanipennis, though brought to this country in some abundance by Mr. Wallace, was up to that time exceedingly rare in collections, the only specimen previously known to me being one in my own cabinet collected in Sumatra by Sir Stamford Raffles. The two species, although agreeing very closely in form, sculpture and coloration, may be readily known from each other by the relative proportion of their antennæ; in L. cyanipennis these organs are at least two-thirds the length of the body; in L. Lacordairii they do not exceed one-half its length. I possess a series of individuals of both species, and I do not find the least tendency to approximation between the two; all the specimens from India, Siam and Birmah agreeing in having short antennæ (as described by Lacordaire); all those from Sumatra and other parts of the Malay Archipelago, on the other hand, having them elongate. The synonymy ought to stand thus:—

Elytra rather more than three times the length of the thorax, flattened along the back, being slightly depressed along the anterior portion of the suture; the basilar space on each elytron indistinctly elevated; humeral callus rather prominent, the puncturing in front on the basilar space and anterior half of the suture coarse and deeply impressed, the stria next the suture deeply sulcate, interspaces between the basilar space and middle of elytron transversely wrinkled. Hinder thighs scarcely thicker than the rest, shorter than the abdomen. Abdomen and legs covered with short adpressed golden or silvery sericeous pubescence.
The following species is unknown to me, but probably belongs to the genus Lema.

Hab. Borneo.
Head elongate-trigonate; eyes black, deeply notched; antennæ very robust, scarcely more than half the length of the body, thickened from beyond the second joint, scarcely tapering at their apex; joints cylindrical, the terminal joints being scarcely more slender than the preceding ones. Thorax about one-fourth longer than broad, sides moderately constricted in their middle; upper surface smooth, nitidous, impressed on the middle disc with some very minute punctures, only visible under a lens. Scutellum trigonate, its apex obtuse; surface covered with adpressed sericeous hairs. Elytra much broader than the thorax, but nevertheless narrower than in C. semipunctata, parallel, broadly depressed transversely below the basilar space, the base itself moderately elevated; surface punctured entirely as in C. semipunctata, with this exception, that the rows of punctures are quite obsolete below the middle of the elytra, a single row of fine punctures near the suture, and another on the outer margin, alone excepted, the place of the absent punctures being indicated however by a small piceous spot. The pubescence on the body beneath is much abraded in the solitary specimen before me, but that on the abdomen appears to be arranged in four rows of fasciculi.

Hab. Dory, New Guinea.
Head deeply constricted behind the eyes, face triangular, excavated between the eyes, impressed at the apex of the epistome with a short longitudinal groove; antennæ longer than half the length of the body, moderately robust, slightly tapering at their extremity, but scarcely fusiform; joints cylindrical, the first obscure rufous, nearly globular, incrassate, second shorter than the first, third and fourth equal, each being twice as long again as the second, fifth almost as long as the two preceding united, sixth and following nearly equal, severally rather shorter than the fifth.
Thorax subquadrate, cylindrical, nearly impunctate, being only impressed here and there with a few very remote punctures. Elytra much broader than the thorax, distinctly raised, basilar space bounded beneath by a broad transverse depression; surface smooth and shining; along the sutural margin, here and there on the basilar space, on the transverse depression and along the exterior half of the lateral border, which is also longitudinally sulcate, are a number of large deep impressions, which evidently form part of the rows of punctures common to the majority of the species of the genus; over the remainder of the surface these punctures are entirely obliterated, their course being only indicated by very faintly-marked longitudinal grooved lines. Abdomen smooth, sericeous; mesosternal process narrow, tapering from base to apex.
This species, in its hairy scutellum, in the form of its antennæ and the puncturing of its elytra, closely approaches C. semipunctata; it is however a much shorter and broader insect; the antennæ are also shorter and the mesosternal process narrower; in C. semipunctata this latter part is broader, and has its sides subparallel. Var. A resembles C. semipunctata in colour, but has the elytra covered with the usual number of rows of piceous dots, which are smooth and impunctate, a certain number only at the base, as in the type, being impressed each with a single deep fovea.
6. Crioceris biplagiata, n. sp.
Oblonga, subcylindrica, nitido-fulva, utriusque elytri plagâ longitudinali paullo ante medium fere ad apicem extensâ antennisque nigris; tibiis tarsisque piceis; antennis robustis, filiformibus; thorace latitudine paullo longiori, lateribus modice coarctato, disco impunctato.

Hab. Morty Island.
Face subelongate-trigonate, clothed with adpressed coarse hairs; neck deeply constricted behind the eyes, the latter angulate-emarginate; epistome not extending upwards above the insertion of the antennæ, a deep longitudinal groove passing from its apex to join the frontal grooves; antennæ half the length of the body, robust, cylindrical, the basal joint short, rufous, the second moniliform, third, fourth and fifth each increasing both in length and thickness, the remaining joints each about equal to the fifth. Thorax cylindrical, its lateral constriction occupying about the middle third of the side, anterior margin convex; upper surface without
basal impression, smooth, impunctate. Scutellum elongate-trigonate, closely covered with adpressed silvery hairs. Elytra much broader than the thorax, oblong, subcylindrical, basilar space elevated, bounded beneath by a broad shallow depression; within the humeral callus is a broad longitudinal groove; each elytron covered with eleven rows of piceous dots, the first short; it will be found on examination that a few only of these dots on the basal portions of the five or six rows nearest the suture are impressed each with a single fovea; on the rest of the surface these dots are smooth and impunctate; interspaces also impunctate; on the hinder portion of each elytron the rows are lost in the longitudinal black patch. Body beneath clothed with adpressed silvery sericeous hairs; hinder thighs scarcely thicker than the others, extending for a short distance beyond the third segment of the abdomen. Mesosternal process narrow, tapering from base to apex.
It is with great doubt that I separate this insect from C. obliterata; in form of antennæ, thorax, mesosternal process and in the mode of punctation of elytra, it exactly agrees with that species; in coloration it is intermediate between the type and var. A; it differs otherwise in the elytra being narrower and more cylindrical above; it is however very probable that in a series of examples this character would be found to vary, in which case it must be considered only a variety of obliterata.

This insect is one of the most abundant and widely spread in the present genus, being commonly sent from almost every portion of the Asiatic quarter of the globe east of Siberia; as might be expected in a species possessing so extensive a geographical range it is highly variable both in form and colour, and has consequently been described by the older authors and by Lacordaire under many different names; the species, at its extreme points of divergence, presents two well marked types, one broad, less parallel and much more robust, the other longer, narrower and more parallel; between these exists an unbroken chain of intermediate varieties, thus proving that they belong to only one highly-variable species. Although not entitled to the rank of sub-species or local varieties, all the intermediate forms being found more or less abundantly throughout the whole geographical range of the species, still the first or broader type is the dominant one in Southern India, Ceylon and the Malay Archipelago, whilst the second or elongate form is the one most usually met with in Assam, Northern India and China.

Head deeply constricted behind the eyes, face triangular, front remotely punctured; antennæ shorter than half the length of the body, subincrassate, outer joints slightly compressed and subperfoliate, eyes notched. Thorax subquadrate, scarcely broader than long; sides constricted in the middle; above subcylindrical, punctured as is C. impressa, the single longitudinal row of punctures down the middle of the disc being also present as in that species. Elytra oblong, much broader than the thorax, slightly dilated behind, their apex broadly rounded; above convex, indistinctly flattened along the back, transverse depression below the basilar space usually obsolete, at other times present, although indistinct; punctures arranged in eleven longitudinal rows, the first of which is very short; the punctures are large, deeply impressed, and placed at irregular intervals on the anterior half of the rows; on the hinder half they become much smaller and indistinct, the rows themselves being frequently entirely obsolete; the inner row next the suture is however always sulcate on the hinder portion of its course, and, together with one or two of the outer striæ, remains always entire; interspaces smooth, impunctate. The amount of fulvous colour on the surface varies greatly; in some specimens, the black ground occupies almost entirely the posterior three-fourths of the surface, the basal fourth, and a narrow line extending round the outer limb, alone being fulvous; in others the fulvous colour is extended inwards so greatly in all directions (more especially however at the base and apex) as to leave only a common central black patch. Under surface clothed as in C. impressa, but the sericeous patches on the surface of the abdomen are less strongly defined. Very closely allied to C. impressa; setting aside colour, the only difference between the two species is in the form of the process of the mesosternum; in C. impressa this part is oblong-quadrate, with its apex broadly truncate; in C. Clarkii it is subtrigonate, with its apex obtusely truncate.

Head deeply constricted behind the eyes; face forming a somewhat elongated triangle; front smooth, without longitudinal impression; antennæ scarcely half the length of the body, somewhat slender, filiform, fifth joint shorter than the two preceding united, three lower joints rufous, the rest black; eyes broadly notched. Thorax subquadrate, subcylindrical, sides deeply constricted in the middle, surface smooth, nearly impunctate, a few remote punctures being only visible on the disc under a lens; in some specimens a row of punctures similar to that in C. impressa runs down the middle of the disc. Scutellum forming an elongated triangle, the apex of which is rounded; its surface glabrous. Elytra much broader than the thorax, nearly four times its length, oblong, sides nearly parallel, apex broadly rounded; above convex, transversely but obsoletely depressed below the basilar space, longitudinally impressed within the humeral callus; each elytron with eleven rows of punctures, the first short; punctures placed at more regular intervals on the striæ than in C. Clarkii, deeply impressed in front, very small and finely impressed on the hinder half of the elytron, but nevertheless distinct to the apex; interspaces smooth, impunctate. The black colour on the elytra varies in extent, in some specimens occupying less than half, in others covering two-thirds of the surface. Abdomen somewhat sparingly clothed with adpressed fulvous hairs, which form, however, a distinct row just within the edge of each segment.

Head deeply constricted behind the eyes; face elongate-trigonate; front impressed with a longitudinal groove; antennæ filiform, somewhat slender, two-thirds the length of the body, pale fulvous, apex of terminal joint fuscous; eyes angularly notched. Thorax subcylindrical, constricted on the sides, surface smooth, impressed with a very few minute punctures, arranged on the disc in a longitudinal row. Hinder tibiæ paler than the others.
The very robust form and dilated elytra will at once distinguish this species from C. terminata; the antennæ are much longer and entirely filiform, and the fourth joint distinctly longer than the third; in C. terminata these two joints are equal.

Head deeply constricted behind the eyes, face elongate-triangular, forehead smooth, impressed behind with a short longitudinal fossa; antennæ moderately robust, nearly filiform, slightly thickened from beyond the fourth joint, about half the length of the body; eyes notched. Thorax subquadrate, subcylindrical, sides deeply constricted at their middle, upper surface smooth, remotely impressed with fine punctures. Scutellum forming an elongate triangle, its apex rounded. Elytra much broader than the thorax, more than three times its length, sides parallel, apex
regularly rounded; above convex, indistinctly impressed at the base within the humeral callus, transversely depressed below the basilar space, surface smooth and shining, each elytron with eleven rows of fine punctures, visible to their apex, the first short; interspaces smooth and flat, impunctate. Legs moderately robust, hinder thighs scarcely thicker than the others, equal in length to the first two segments of the abdomen. Abdomen sparingly covered with fine adpressed concolorous pubescence, edges of the segments clothed with a row of coarse hairs.
This insect is nearly allied to C. Pfeifferæ; the pale antennæ and legs, together with the much smaller extent of the red colour on the elytra, will at once separate it from that species. I possess three specimens of the insect from two localities, but they do not show any variation in colouring.

Hab. Manilla.
Entirely similar to T. Westwoodii, with the exception of the following characters:—Colour flavous, the eyes and apex of jaws black, the labrum, the tarsi above, and the claws fuscous; humeral callus with its apex rather more produced, almost subacute; hinder thighs less thickened, the anterior spine being produced nearly in the same line with the under edge of the thigh, and forming a much less distinct angle with it than in the preceding species.
The above characters may appear very slight, but combined with the difference of colour they are constant in the five individuals (two of T. Cumingii and three of T. Westwoodii) that I have been able to examine; they appear to me, in a family where the species are separated from each other by such slight differences, sufficient to divide the two.

Front plane, the central fovea, present in the two preceding species, obsolete, surface irregularly but not closely punctured; upper half of epistome slightly raised, smooth and shining, nearly impunctate; antennæ nearly half the length of the body, joints formed nearly as in the preceding species, the second and fourth equal, each slightly longer than half the length of the third; joints in the dilated portion rather less trigonate, subquadrate, the fifth only slightly longer than the fourth, four basal joints flavo-fulvous;
the rest pale fuscous; eyes and apex of jaws black. Thorax transverse, sides obliquely converging from base to apex; upper surface transverely convex, coarsely but not closely punctured; apical margin truncate, obsoletely sinuate in the middle, surface on either side, just behind the margin, transversely grooved; on either side at the base is a protuberance similar to the one in the preceding species. Scutellum trigonate, its apex truncate, indistinctly notched. Elytra similar in form and punctation to those of T. Westwoodii, the apex of the humeral callus rather more produced. Body beneath clothed with coarser hairs than the upper surface; abdomen entirely nigro-piceous, with the exception of the extreme base, where it passes between the hinder coxæ. Metasternum transversely striolate, mammary prominences more elevated than in either of the two foregoing insects; apex of fifth segment with a semicircular incision, immediately in front of which is a shallow oblong fovea. Hinder thighs less thickened than in T. Westwoodii; spines on their under surface similarly arranged to those in that insect; apex of claws piceous.
The absence of a frontal fovea, the pale fuscous antennæ and broader thorax, together with the more prominent mammary processes on the metasternum, will separate this species from its congeners.
The following species of this family, published since the date of Mons. Lacordaire's monograph, has not been seen by me.

Head short, subtrigonate, face coarsely and deeply punctured, impressed at the apex of the epistome with a deep fovea, front obliquely rugose-strigate on either side, middle of forehead remotely punctured; eyes large, their inner edge deeply notched; antennæ with the first four, together with the basal portion of the fifth and sixth joints obscure fulvous, the rest black, second and third joints short, equal, obovate, the others compressed and dilated, trigonate. Thorax twice as broad as long, sides obliquely
rounded and converging from base to apex, anterior angles distinct, subacute; basal margin truncate, obsoletely sinuate on either side, medial lobe slightly produced, obtusely rounded; upper surface subcylindrical, finely but distinctly punctured, the puncturing more crowded in front; on either side the middle disc is a large deep fovea; in front of the basal margin near the hinder angle is an oblique depression; on the basal half of the surface, leaving a narrow fulvous line on the extreme hinder margin, is a broad transverse black band, abbreviated on either side near the lateral border, its medial portion anteriorly produced, the front edge trisinuate on either side, middle deeply emarginate. Scutellum forming an elongated triangle, the sides straight, the apex subacute, shining black, the extreme apex obscure fulvous. Elytra sinuate on the sides, narrowed posteriorly, surface rather more coarsely punctured than the thorax, smooth and shining; the black bands on the surface of each are broad and have their edges irregularly sinuate. Body beneath covered with coarse adpressed sericeous hairs; abdomen closely punctured.
Without being parallel, this species is much narrower and less cylindrical than C. 12-maculata, Fabr., from which insect it may also be known by the black head and scutellum, and the different arrangement of the black markings on the thorax and elytra. I have made the above description from a single specimen, a ♂, taken by Mr. Wallace in the Island of Timor; it is probable that, in a series of individuals, the markings would vary as in C. 12-maculata, and the transverse bands on the elytra break up into spots.

Fam. CHLAMYDÆ.
Sub-Fam. CHLAMYDEÆ, Lac.
Mon. Phyt. ii. p. 636.
I have ventured to differ from M. Lacordaire in raising the Chlamydæ from the rank of a sub-family of the Clythridæ to that of a separate family. These insects appear to me to occupy a place midway between the true Clythridæ and the Cryptocephalidæ, presenting strong affinities with either group.
Agreeing with the former principally in the form of the antennæ, with the latter in the presence of a prosternum and in the entirely exposed pygidium, they differ from either in possessing prothoracic grooves for the reception of the antennæ, being allied by this last character to the Lamprosomidæ. The other sub-families of Lacordaire's family Clythridæ, with which, however, I have not to deal in the present work, ought also, in my opinion, to form separate families.
In support of the above view I may mention that M. Lacordaire himself, in his Introduction, places the genus Chlamys amongst the Cryptocephalidæ, whilst in the body of the work he makes it a sub-family of the Clythridæ, showing clearly the difficulty he had in determining to which of the two groups it was most closely allied.
I have not given a definition of the family Chlamydæ, it being sufficient to refer to the characters of the Chlamydeæ, as laid down by Lacordaire.

Head closely punctured; jaws black; third and fourth joints of antennæ slender, equal. Thorax coarsely rugose-punctate, the
interspaces forming close elevated reticulations; gibbosity impressed with a broad, shallow, longitudinal groove, which, distinct at its base, is gradually lost on the anterior portion of the gibbosity. Elytra rugose-punctate, the interspaces along the middle of the disc forming four or five irregular longitudinal ridges; each elytron furnished with a number of elevated tuberosities; those on the anterior half of the disc transversely compressed, those near the apex more strongly raised and irregular in shape, their surface covered with large round reticulations: these tuberosities are placed as follows, viz. the first at the lower edge of the basilar space, half-way between the suture and humeral callus; the second about the middle of the length of the elytron, placed obliquely half-way between the first tubercle and the suture; the third on the suture itself, at some little distance below its middle; these three form an oblique line across the disc; secondly, three other tuberosities, placed respectively a little more outwardly and lower down than the three preceding, form another oblique line, parallel to the former; and, lastly, there are two or three tuberosities on the apical portion of the disc, more towards the outer angle.

Head closely punctured, the interspaces forming raised reticulations over the surface. Thorax strongly gibbose, the gibbosity narrowed posteriorly into an acute angle, its surface covered with six raised carinæ; the middle pair parallel, confluent at their base, produced anteriorly to a short distance within the apical border of the thorax; the four others arise two on either side from the central pair, and run obliquely outwards and forwards down the sides of the gibbosity; whole surface of thorax closely punctured, and covered in front with more or less distinct raised reticulations. Elytra parallel, more coarsely and deeply punctured than the thorax, the disc of each furnished with three indistinctly-raised lines; the first of these commences a short distance below the base, near the scutellum, and, running nearly parallel to the suture, terminates a short distance below the middle of the latter; the second, tuberculate at its base, commences at the basal margin, halfway between the suture and humeral callus, runs nearly parallel to the first, and ends by uniting with its apex by means of a short transverse ridge; the third, arising from the humeral callus, runs obliquely inwards to join the second at about the middle of its course, a short ridge connecting the
two; from this point it is prolonged downwards nearly parallel to the latter half of the second line, and becomes gradually lost on the surface of the disc; in addition to these raised lines, each elytron is furnished with five large tubercles, one placed near the outer margin just below its middle, the others on the subapical space.

I have founded the present genus for the reception of two new species of Cryptocephalidæ, collected by Mr. Wallace. In form of thorax it agrees with Prasonotus and Ditropidus, differing, however, in having the apex of its basal lobe entire and received into
the base of the scutellum instead of itself receiving the latter, as in the two above-named genera; from Cœnobius and Achænops, both which genera have the apex of the basal lobe of the thorax received into the base of the scutellum, and have subincrassate antennæ, it is separated in the first case by the distant eyes, in the other by the form of the hinder margin of the prosternum and by its notched eyes; from Cryptocephalus proper it may be readily distinguished by the small horizontal scutellum, the surface of which is entirely received between the margins of the elytra, its apex not being raised in the slightest degree above their level.

The whole upper surface of the body in this interesting species is covered with very minute punctures, from which cause the body appears nitidous or the reverse, according to the light in which it is viewed.

Thorax twice as broad at the base as long; sides rounded, slightly converging in front, the lateral border reflexed; basal margin broadly concave on either side, slightly produced near the medial lobe, the latter broadly truncate, its margin slightly excavated to receive the base of the scutellum; upper surface very convex and obsoletely
gibbous on the disc in front, obliquely depressed on either side near the base; impressed with large deep punctures, which, more distant on the middle of the disc, become closely crowded towards the sides, which are rugose-punctate; base and sides pale rufo-piceous, reflexed lateral margin fulvous. Scutellum subelongate-trigonate, its apex broadly truncate. Elytra strongly lobed at their base, the sides being strongly retrenched behind the dilated portion; this causes the elytra to resemble in shape those of the genus Aspidolopha; upper surface slightly thickened near the scutellum, deeply impressed with large punctures, which are irregularly arranged in longitudinal rows; interspaces thickened transversely, crenulate on the inner disc in front, longitudinally costate towards the apex of the elytron. Pygidium with its apical border concave. Anal segment of abdomen with an unusually large round fovea. Legs slender. Prosternum broader than long, its hinder margin truncate.

Head distinctly punctured; epistome triangular, separated from the face by a grooved line; on either side, just above the insertion of the antennæ, is a slightly raised smooth tubercle; eyes black. Thorax subglobose above, covered with fulvous hairs, which are shorter and less depressed than those of any other part of the body; sides regularly rounded; surface deeply punctured, puncturing crowded and rugose on the sides, somewhat more scattered on the disk, the middle of the latter covered by a large obtrigonate black patch. Elytra oblong, sides parallel, slightly narrowed near the apex, the latter regularly rounded, dehiscent at the sutural angle; above convex; each elytron with eleven sulcate striæ, the first abbreviated, each stria impressed with a single row of irregular punctures, interspaces somewhat raised and subcostate towards the lateral margin, their surface covered with distinct punctures, which render those of the striæ confused; a large subbasal rotundate spot, a common bilobate patch at the middle of the suture, another, larger and oblong-ovate, placed behind the middle, and a small spot placed externally to the humeral callus, shining black.
This insect varies in the number of black spots on the elytra. The patch on the thorax is also sometimes wanting. A second species, A. nigripes, mihi (Journ.

Hab. Celebes.
Head covered with adpressed scales, epistome glabrous, broader than long, distinctly separated from the face by a sutural groove; eyes large, prominent. Thorax rather broader than long, sides rounded, armed with a single row of small teeth, which owing to the rugosity of the surface are not easily seen; upper surface transversely convex, slightly flattened on the middle of the disk,
the latter clothed with adpressed scales, which, radiating from the centre, are spread equally over the whole surface. Elytra stained with irregular obscure rufous patches, coarsely striate-punctate, convex, scarcely excavated below the basilar space; interspaces thickened and strongly elevated, especially on the sides, towards the apex they form longitudinal costæ; they are clothed with adpressed white scales, scattered irregularly on the surface, and forming here and there large ill-defined patches.
This species may at once be known from D. serraticollis by the absence of the erect setæ on the surface of the elytra.

Thorax transversely convex above, slightly flattened on the disk; surface rugose-punctate. Elytra coarsely striate-punctate, somewhat closely clothed with adpressed scales, which are distributed nearly equally over their whole surface.
This species may be known from D. rugicollis by the absence of teeth on the lateral margin of the thorax, by the larger wedge-shaped epistome, and by the more equal distribution of the scales over the surface of the elytra.

Thorax scarcely longer than broad, subcylindrical, sides nearly regularly rounded; surface coarsely but not deeply rugose, covered on the disk with raised reticulations; clothed with adpressed scales, which are more crowded near the
lateral margins, where sometimes they form an ill-defined longitudinal vitta. Elytra deeply and coarsely striate-punctate, subnitidous, interspaces on the middle of the disk raised and forming indistinct transverse ridges, scales clothing their surface collected into irregular ill-defined patches.
10. Demotina rufopicea, n. sp.
Oblonga, subcylindrica, rufo-picea, subnitida, albo-squamosa; thorace latitudini æquilongo, subcylindrico, rugoso-punctato; elytris profunde striatim punctatis, interstitiis elevatis, squamis hic illic congregatis, plagas albidas formantibus; epistomate cuneiforme.

Head clothed with coarse adpressed scales; epistome wedge-shaped, not distinctly separated from the face, its surface glabrous; eyes large, prominent. Thorax subcylindrical, sides converging in front; surface coarsely rugose-punctate, clothed with adpressed whitish scales. Elytra coarsely and deeply striate-punctate, the interspaces thickened, scales on the surface arranged in irregular patches.
Very nearly allied to D. parvula, and very possibly only a variety of that insect; it differs chiefly in the coarser punctation of the elytra.

Hab. Ceram.
Head coarsely punctured; face clothed on either side within the eyes with adpressed white scales; antennæ slightly thickened towards the apex, slender, two-thirds the length of the body, pale fulvous, six outer joints piceous. Thorax scarcely broader than long, subcylindrical, sides slightly rounded, converging in front; surface closely covered with large round shallow punctures, sparingly clothed with white scale-like hairs, either side of the disk with a broad longitudinal vitta of adpressed white scales. Elytra striate-punctate, sparingly clothed with white scale-like hairs;
each elytron with a short subsutural stripe placed at the apex, another submarginal, also apical and confluent with the former, and also with four small patches arranged as follows, viz.:—one just before the middle, two others subparallel just behind the middle, and the fourth halfway between the middle and apex. These markings are all formed of white adpressed scales.
The black, shining, nearly glabrous body of this insect, contrasted with the well-defined patches of white scales ornamenting the surface, gives it an entirely different aspect to any other known species of the genus.

The present genus is well represented in the Malay Archipelago, three-fourths of the Asiatic species being natives of that part of the world. The antennæ of all the males have a tendency to elongate, the club at the same time being distinctly narrower than in the females of the same species. In one, C. monstrosus, these organs are filiform, the five upper joints, although slightly compressed, not being broader than those immediately below them. In the female of monstrosus the antennæ are much shorter and distinctly subclavate; the same sex in this species (as well as in three or four others belonging to the same section of the genus) present the remarkable peculiarity of having their elytra covered with a number of irregular tubercles, whilst the elytra in the males are simply punctured in the ordinary way.
* The exception to this is a single oblong tubercle, more or less distinct, which exists in nearly all the species; it is situated just below the humeral angle, immediately within the outer margin of the elytron.

Head closely punctured, lower margin of face separated from the epistome and encarpæ by a deep groove, obtusely angled, lateral angles distinct, medial produced; epistome triangular, sides slightly rounded; surface closely rugose-punctate, shelving down above until it reaches the level of the sutural groove, thus rendering the latter indistinct in front; encarpæ cultriform, smooth, impunctate, impressed in the middle with a broad oblique groove; antennæ nearly equal to the body in length in the ♂, robust, filiform; rather more than half the length of the body in the ⁀, six outer joints compressed and moderately dilated. Thorax nearly a third broader than long; sides rounded, slightly converging in front; surface convex, closely and somewhat finely punctured. Elytra much broader than the thorax; sides slightly but regularly narrowed from the shoulders backwards, their apex subacutely rounded, above convex, transversely excavated on each elytron below the basilar space and also within the humeral callus, the
latter distinctly raised into an oblong ridge; surface closely covered with coarse punctures; on the disk of each elytron are three or four obsoletely raised longitudinal vittæ; in the ⁀ the elytra are covered with numerous strongly raised tubercles, placed in about eight longitudinal rows; these become obsolete on the hinder third of the surface, with the exception of the outer row but one, which extends the whole length of the elytron, and is terminated at the suture by a large obtuse tuberosity; outer edge of intermediate tibiæ sinuate near the apex; claws appendiculated.
Not having retained the genus Corynoëides, founded by the Rev. H. Clark on the present insect, I have been obliged to change his specific name tuberculatus, the same having been previously used for another species (post, p. 103).

The ⁀ also differs from the ♂ in the following characters: parallel to the lateral border is a longitudinal ridge, the basal portion of which is broken up into a number of small tubercles; on the hinder disk it is lost in the general surface of the elytron, with the exception of the extreme apex, where may be seen the traces of an obtuse tubercle; the surface on the inner side of the ridge is longitudinally excavated along the anterior two-thirds of its course; the depression surrounding the base and outer border of the basilar space is more deeply excavated than in the ♂; on the anterior half of the outer disk are a number of irregular tubercles, which vary in number in different individuals; three or four of these are arranged in a longitudinal ridge, which, commencing at the humeral callus, runs for a short distance along the inner border of the longitudinal excavation.

This species agrees so closely with C. biseriatus that a detailed description is unnecessary. I shall therefore only point out the differential characters between the two species; in C. cupreatus the anterior margin of the front is obtusely rounded, not produced in the middle, and not sinuate on either side; the antennæ are shorter, scarcely exceeding half the body in length; the thorax is more transverse, less narrowed in front, the sides being less obliquely deflexed; lastly, the elytra are much less regularly punctured, the double rows of punctures being less distinct and (on the middle disk) almost entirely obsolete. Both species may be known from their congeners by the transverse closely punctured thorax.

Thorax distinctly broader than long: sides nearly straight and parallel from the base nearly to the middle, thence obliquely rounded and converging to the apex; anterior angles thickened, posterior armed with a short tubercle; above transversely convex, sides strongly and obliquely deflexed in front, surface deeply but remotely punctured. Elytra broadly oblong, convex, deeply impressed below the basilar space and within the humeral callus, the latter prominent; surface finely punctured, the punctures arranged in uneven longitudinal rows; in the ⁀, placed within and parallel to the lateral border, is a strongly raised costa, which, commencing just below the humeral callus, extends the whole length of the elytron to the sutural margin, and between this costa and the outer border is a slightly raised flexuose vitta.
The deep depression surrounding the outer and lower edges of the basilar space separates C. approximans from its allies. The ⁀ of C. costatus (post, p. 110), which possesses the same character in a less degree, may be known from the ⁀ of the present species by the close irregular punctation of the elytra, together with the much more strongly raised costa on the outer disk.

Head very distantly punctured, front impressed with the usual longitudinal groove; anterior border separated from the encarpæ and epistome by a deep sutural groove, very obtusely angled, obsoletely excavated on either side, the apex produced into an obtuse lobe; epistome scarcely longer than broad, campanuliform; encarpæ broadly cultriform, their surface smooth, nearly plane, not thickened above; antennæ two-thirds the length of the body, five upper joints moderately dilated, nearly equal in width, black. Thorax slightly broader than long, sides rounded and converging from base to apex, more quickly rounded in front, nearly parallel at the base, hinder angles armed with a short tooth; above sub-cylindrical, sides in front broadly and strongly deflexed; surface deeply but remotely punctured. Elytra oblong, convex, not very strongly punctured, punctures irregularly arranged in longitudinal rows, which indistinctly approximate in pairs; below the basilar space is a transverse excavation, which, commencing a short distance from the suture, terminates just below and within the humeral callus, its outer half much more deeply excavated than the inner portion; humeral callus moderately thickened, bounded within by a longitudinal depression, which unites at its lower end with the transverse excavation.
Corynodes propinquus and the two preceding species, mutabilis and fulgurans, are very closely allied, and I formerly considered them as mere varieties of one species. C. mutabilis and fulgurans may be known from each other by the difference in colour and by the different form of the anterior border of the front; in C. fulgurans also the punctuation of the elytra is finer, and the interspace between each double row of punctures broader; in C. propinquus the form of the anterior edge of the front differs from that of either of the two preceding species, and the rows of punctures on the elytra are less distinctly arranged in pairs.

Epistome triangular, emarginate at the apex, separated from the encarpæ by a deep groove, its surface coarsely punctured; front remotely punctured, its anterior margin trilobate, the intermediate lobe semiovate, distinctly produced, its surface longitudinally depressed and excavated, forming the lower extremity of a deep longitudinal groove which runs downwards from the vertex; club of antennæ five-jointed, moderately dilated, the seventh to the ninth joints increasing in width, the tenth and eleventh equal in width to the ninth; encarpæ subtriangular. Thorax subquadrate, sides nearly straight and parallel from the base to beyond the middle, thence obliquely rounded and converging to the apex, posterior angles armed with a short obtuse tooth; upper surface subcylindrical, deflexed in front, subremotely or remotely punctured. Scutellum semiovate, smooth, impunctate. Elytra much broader than the thorax, sides parallel; above strongly convex, the humeral callus subprominent; basilar space bounded beneath by a semicircular depressed line, on the space itself are two or three broad short costæ; surface of the elytra covered with rather coarse punctures, which are arranged in numerous somewhat irregular longitudinal rows, which towards the apex approximate in pairs; on the disk and apex are several indistinct costæ; the basal border, together with the suture in front, greenish-blue.
The elongate form, coarser punctation of the elytra, and peculiar antennæ, will at once distinguish C. longicornis from all the other species which have a trilobate front.

Head coarsely but remotely punctured; front impressed with a deep longitudinal groove, which runs downwards as far as the anterior margin, the latter separated from the encarpæ and epistome by a deep sutural groove, trilobate, the medial lobe produced; epistome longer than broad, campanulate, rugose; encarpæ cultriform, smooth and impunctate, their upper half scarcely thickened; antennæ more than half the length of the body, five upper joints broadly dilated, black. Thorax slightly broader than long, sides nearly straight and parallel behind the middle, thence rounded and converging to the apex; above transversely convex, sides strongly deflexed in front, surface coarsely and deeply but subremotely punctured. Elytra oblong, parallel, obsoletely depressed below the basilar space (the depression visible only when viewed obliquely); humeral callus prominent, bounded within by a longitudinal depression; surface somewhat coarsely punctatestriate, the puncturing equally strong towards the apex of the
elytra, where the striæ have a tendency to coalesce in pairs and form a single irregular row of punctures; the interspaces on the hinder disk obsoletely thickened.
C. suaveolus is likely to be confounded with the two foregoing species; it may be known from either by the entire absence of the transverse depression below the basilar space on the elytron, and by the much more coarse and close punctuation of its thorax. C. Waterhousii differs from C. Lorquinii in having a broader thorax, and in the puncturing of its elytra being continued of equal strength to the apex; in Lorquinii the punctures are much finer on the hinder disk, and occasionally obsolete.

This insect is so nearly allied to C. fraternus, (differing chiefly in the form of the lower border of the face,) that at first I had considerable hesitation in considering it as more than a local variety of that species; as, however, it comes from an entirely different locality, I have thought it better for the present to keep it distinct. The epistome, instead of being trilobate as in C. fraternus, is truncate, produced in the middle into a distinct lobe, the sides being each distinctly but slightly concave. The thorax is slightly broader and obsoletely excavated on either side the disk. In the form and sculpturing of the elytra it does not present any difference from C. fraternus.

Thorax subconic, sides nearly straight and converging from base to apex, hinder angles furnished with a short obtuse tubercle; surface coarsely and closely punctured. Elytra narrowly oblong, subcylindrical, not excavated below the basilar space; humeral callus prominent; surface coarsely and closely punctured, punctures near the suture and on the hinder disk arranged in longitudinal striæ, interspaces strongly elevate-reticulate, costate on the hinder disk; on the outer disk are three longitudinal costæ, which are more or less interrupted by the reticulations of the general surface.
This species is at once known from its congeners by the rugosity of the upper surface of the body, greatly resembling in this respect certain species of Colaspis.

Hab. Sumatra.
Face impressed with large foveolate punctures, continuous with the encarpæ and apex of epistome, its lower margin trilobate; epistome rather longer than broad, subcampanulate, surface coarsely rugose-punctate, sides separated from the encarpæ anteriorly by a fine sutural line, which gradually deepens posteriorly and terminates on the side of the apex of the epistome in a deep fovea; surface of encarpæ irregularly thickened, depressed above, point of junction with the front indicated by an ill-defined sutural line; antennæ nearly two-thirds the length of the body, five outer joints broadly dilated, black, the seventh to the ninth gradually increasing in width. Thorax nearly one-fourth broader than long, sides nearly straight and parallel from the base to before the middle, thence rounded and converging to the apex; above transversely convex, sides strongly deflexed in front, surface deeply and remotely punctured. Elytra broadly oblong, their apex broadly rounded, very convex, transversely impressed below the
basilar space, the depression nearly obsolete on the inner disk, broad and well marked below the humeral callus, which is prominent, bounded within by a longitudinal depression; surface finely but distinctly punctured, the punctures arranged in longitudinal rows, which approximate in pairs on the inner disk and towards the apex of the elytron. Outer edge of intermediate tibiæ sinuate towards the apex.
The green colour and the short robust form (which strongly resembles that of C. robustus and its allies), together with the finer and less close punctation of the surface, and the more acutely appendiculated claws, will at once separate this insect from C. trilobatus.

Head very coarsely and irregularly punctured, more or less broadly impressed longitudinally on the front, which is continuous with the encarpæ and apex of epistome, excavated on either side at the apex of the latter; surface of encarpæ irregular, deeply punctured; epistome semiovate, somewhat variable in width, rather more finely punctured than the front; antennæ more than half the length of the body, six outer joints broadly dilated, the sixth to the ninth gradually increasing in width, the fourth and fifth slightly compressed, the latter subtrigonate. Thorax subconic, sides nearly straight and converging forwards, more quickly at the extreme apex; surface very deeply and irregularly punctured. Elytra without transverse depression at the base, punctured in a similar manner to C. peregrinus (post, p. 132); the coloration usually constant, occasionally varying; the apical patch, which occupies nearly the hinder third of the elytron, and
together with its fellow forms an angle on the suture, remains in all the individuals I have hitherto seen without change, but the anterior patch occasionally varies very considerably; in some specimens it unites at the suture, and sends a narrow line upwards to the scutellum; in others, as Var. C, it is not produced posteriorly, the hinder border forming a transverse straight line, whilst anteriorly it extends upwards to the base, entirely covering the shoulder; in Var. D it becomes smaller and irregularly cruciform.

Hab. Philippine Islands.
Front very coarsely rugose-punctate, its lower edge continuous with the encarpæ and apex of epistome; surface of encarpæ irregular, impressed with several large punctures; epistome wedge-shaped, more finely punctured than the front; on either side, just above its apex, is a large deep irregular fovea; antennæ more than half the length of the body, six outer joints broadly dilated, the sixth to the ninth gradually increasing in width, apex of apical joint obtusely angulate, extreme apex truncate, the fourth and fifth joints compressed, the latter equal in length to the sixth, narrowly dilated from base to apex. Thorax scarcely longer than broad at the base, subconic, sides slightly rounded and converging from base to apex, hinder angles acute; surface deeply and remotely punctured. Elytra narrowly oblong or oblong, parallel, convex, distinctly excavated below the basilar space; humeral callus moderately prominent, bounded within by a longitudinal excavation; surface somewhat finely but deeply punctured, the punctures closely arranged in numerous longitudinal rows.
Very nearly allied to C. peregrinus (p. 132); it differs externally slightly in colour, most of the specimens being of a greenish blue, individuals without any green tint being apparently rare. The thorax is more distantly punctured, and the fifth joint of the antennæ,
although compressed and dilated from base to apex, is narrower and less distinctly triangular than in C. peregrinus; the joints of the club are rather longer and less transverse. The principal differential character, however, exists in the depression below the basilar space of the elytra, which is very distinct and well-defined in the present species, but nearly obsolete or entirely absent in peregrinus and allied species.

Head very coarsely and deeply punctured, front rugose and irregularly excavated at its lower border, which is continuous with the encarpæ and apex of epistome; surface of encarpæ irregular, impressed with a few large punctures; epistome wedge-shaped, more closely and finely punctured than the front; antennæ more than half the length of the body, six outer joints broadly dilated, the sixth to the eighth gradually increasing in width; the fourth and fifth joints also compressed, more or less trigonate. Thorax subconic, scarcely broader at the base than long, sides straight and slightly converging forwards, rounded, and more quickly converging before the middle, hinder angles acute; surface very coarsely and deeply punctured. Elytra coarsely and closely punctured, punctures near the suture and on the outer border arranged in longitudinal rows, those on the middle disk placed without order; the transverse excavation below the basilar space is either ill-defined or entirely absent; humeral callus scarcely prominent.
The coarser punctation of the elytra, together with the more parallel form, will separate this species from C. antennatus; the absence of the transverse depression on the elytra from C. indigaceus; the thorax is usually more closely punctured than in either species.

Elytra very similar in sculpture to S. curculionoides, with this exception, that the costæ visible on the hinder portion of the surface in the former species, in the present case extend to the base, but are fewer in number and less distinct; each elytron has two patches at the base, one covering the humeral callus, the other subbasal, placed midway between the shoulder and the
suture, an irregular transverse band across the middle, abbreviated externally, a subsutural vitta (connected with the lower edge of the transverse band by a short branch) running parallel to the hinder two-fifths of the suture, and, lastly, an oblong patch placed on the outer disk halfway between its middle and apex.

Head strongly but not very closely punctured; epistome not distinctly separated from the front, its anterior border concave-emarginate; antennæ two-thirds the length of the body, slightly thickened towards the apex. Thorax not longer than broad, subcylindrical, subglobose above, sides slightly but regularly rounded, lateral border nearly obsolete; surface closely rugose-punctate, clothed with subdepressed griseous hairs. Elytra broadly oblong, much broader than the thorax, not depressed below the basilar space, clothed with silvery-white hairs, surface coarsely and closely punctate, interspaces thickened.
The non-metallic dull colouring of C. murina, together with the close irregular punctuation of its thorax and elytra, give it an entirely different aspect to that of any other insect of the genus; in all structural characters, however, it closely agrees with the metallic species.
Genus RHYPARIDA, Baly.
Journ. of Entom. i. p. 286.
Corpus subquadrato-ovatum, oblongum aut subelongatum, convexum. Caput perpendiculare; frontis margine antico plerumque bilobato; antennis filiformibus aut subfiliformibus, gracilibus; oculis oblongo-ovatis, intus plerumque sinuatis. Thorax conicus aut transversus, lateribus marginatis. Elytra parallela aut apicem versus perparum angustata, apice rotundata, regulariter punctato-striata.

Scutellum as broad at the base as long, subtrigonate, sides rounded. Elytra subparallel, broadly but very slightly excavated below the basilar space; striæ distinctly and somewhat deeply punctured in front, interspaces obsoletely convex; finely punctured behind the middle, interspaces plane.
The plane distinctly-punctured front, and the total absence of sutural lines between it and the epistome, will at once distinguish this species from its allies.
