Descriptions of New Species of Hymenopterous Insects collected by Mr. A. R. Wallace at Celebes. By FREDERICK: SMITH, Esq., Assistant in the Zoological Department of the British Museum. Communicated by W. W. SAUNDERS, Esq., F.R.S., V.P.L.S.

[Read November 3, 1859.]

THE present paper contains descriptions of upwards of 100 species of Hymenoptera new to science, which form part of the second collection made by Mr. Wallace at Celebes. Perhaps the most interesting species described belongs to the genus Dolichurus, a genus which previously contained only a single species, and that indigenous to Europe; the discovery of a second may be regarded as one of the most valuable additions which Mr. Wallace has made to this order of insects. The addition of a new species to the genus Methoca is also extremely interesting; of the previously known species, one is European, a second from Cuba, a third from Canada, and a fourth from Northern India, showing the extensive geographical range of this rare genus of solitary Heterogyna.

The two collections of Hymenoptera from Celebes contain no less than 164 new species, a number far exceeding that which I have found in any similar collection, made in any part of the New World.

Fam. AULACIDÆ, Shuck.

1. TRYGONALYS PICTIFRONS. T. nitidus, niger, distincte punctatus; capite pedibusque albo maculatis; alis hyalinis, apice fuscis.

Female. Length 5 lines. Black; head and thorax with coarse, shallow, confluent punctures; the mesothorax with two oblique longitudinal impressed lines, which enclose, in the middle, one-third of the disk, the lateral portions being irregularly striated longitudinally; the scutellum with a central depression, the metathorax rounded. The face with an ovate spot outside the insertion of the antennæ, two at the base of the clypeus, and an oblong one at the inner margin of the mandibles, white; the head a little wider than the thorax. Thorax: the tubercles, the anterior tibiæ in front, and the intermediate and posterior pairs at their base, white; wings hyaline and iridescent, with a dark fuscous cloud at the apex, commencing at the stigma. Abdomen shining, more finely punctured than the head and thorax, the base with a central longitudinal depression; beneath, more delicately and not quite so closely punctured.

Male. Length 3¾ lines. Closely resembles the female, but rather more finely punctured; the extreme base of the femora and apex of the trochanters are pale, there is also a pale spot on each side of the scutellum and of the postscutellum; the second segment of the abdomen

LINN. PROC. — ZOOLOGY, SUPPLEMENT. 5

[page] 58

has an ovate spot on each side at its apical margin, and the third segment a very minute one; beneath, the apical margin of the second segment is produced into a stout, obtuse, flattened spine.

This genus is characterized and formed for the reception of those species of Megischus in which the submarginal and discoidal cells are obsolete; all the species possess the characters of the genus Megischus, differing only in the neuration of the wings. Mr. Westwood described a species of this subdivision in his monograph of the family, under the name Megischus indicus. I am acquainted with six or seven species, inhabitants of Malacca, Borneo, and Port Natal.

This species so closely resembles Ampulex compressus that perhaps it will be regarded by some persons as only a local variety; I have separated it for the following reasons: in the first place, the head is rounded behind, whereas in A. compressus it is transverse with the angles obtuse, and the eyes are more closely approximate than in that species; the second lateral carina on the metathorax is simple, while in A. compressus it becomes double towards the apex: all the specimens from Makassar are brilliant purple in both sexes.

1. APIS NIGRO-CINCTA. A. capite thoraceque nigris; abdomine pallide ferrugineo, segmentis fasciis nigris; scutello pedibusque pallidis.

Worker. Length 5 lines. Head and thorax black; the scape of the antennæ, the clypeus, labrum, and mandibles pale ferruginous. Thorax: the scutellum and legs pale ferruginous, with the tibiæ and tarsi fuscous, the intermediate and posterior tibiæ pale in the middle; wings hyaline, the nervures ferruginous. Abdomen pale ferruginous, with the apical margins of the segments dark fuscous; beneath entirely pale.

Hab. Makassar.

This species most closely resembles the A. socialis of Latreille, but it is quite distinct, as I have ascertained by a comparison with and an examination of the typical specimen in Mr. Westwood's possession.

Catalogue of Hymenopterous Insects collected by Mr. A. R. WALLACE in the Islands of Bachian, Kaisaa, Amboyna, Gilolo, and at Dory in New Guinea. By FREDERICK SMITH, Esq., Assistant in the Zoological Department, British Museum. Communicated by W. W. SAUNDERS, Esq., V.P.L.S.

[Read May 3, 1860.]

OF the various collections of Hymenoptera which Mr. Wallace has formed in the Indian Archipelago, none has exceeded that whose contents are described in the present paper, in the beauty and variety of the species, as well as in the interest attached to their geographical distribution. Amongst the Formicidœ many new and remarkable forms are both described and figured. I would particularly call attention to the two forms of the worker of Pheidole notabilis. Though convinced that nothing is created in vain, and that every modification of form has its design, adapting it to the fulfilment of conditions necessary in the economy of the particular species, I feel quite unable even to conjecture the purpose of the enormously enlarged head of the worker major of that species.

Another very interesting Ant is a new species of Erichson's genus Amblyopone; the previously described species are either from Tasmania or Australia; that here described is from Bachian.

Two remarkable species are added to the Cryptoceridœ, and a new genus described, which has partly the characters of Cryptocerus, and partly those of Ponera.
