Catalogue of Hymenopterous Insects collected by Mr. A. R. WALLACE in the Islands of Mysol, Ceram, Waigiou, Bouru and Timor. By FREDERICK SMITH, Assistant in the Zoological Department, British Museum. Communicated by W. W. SAUNDERS, Esq., F.R.S. & L.S.

[Read Jan. 15, 1863.]

It will be observed, on comparing the contents of the present collection with others described in previous papers, that the species most widely distributed belong to the families Vespidœ and Sphegidœ, both containing insects of powerful flight; whilst among the apterous genera, or those in which the females are only temporarily winged, as in the Formicidœ, the range of distribution is much more circumscribed; it is, consequently, here that the largest number of new species are found.

In this paper, no less than four new species of the family Thynnidœ are described, one belonging to the genus Ælurus, the first, I believe, that has occurred out of Australia. We hope shortly to be enabled to draw up a set of tables showing the range of geographical distribution of the numerous species of Hymenoptera described in the various previous papers on the insects of the Eastern Archipelago.

Hab. Ceram.

Mr. Wallace says, "Nest on a leaf, small, oval, and of papery texture."

Hab. Waigiou.

This species closely resembles the P. sexspinosus, but differs too much to be regarded as a variety of that species; the form of the head is very different, being more narrowed behind the eyes, the sides being straight; the short, thick, curved spines on the thorax also distinguish it from P. sexpinosus.

21. POLYRHACHIS PAROMALUS. P. niger, lævis nitidusque, thorace spinis duabus acutis postice armato; pedibus obscure ferrugineis; squama spinis duabus acutis curvatis.

Worker. Length 3 lines. Jet-black, smooth and shining; the mandibles ferruginous; the extreme base and apex of the antennæ rufopiceous; the head much narrowed behind the eyes, which are round and prominent; the front of the head very convex.

Abdomen: the node of the peduncle with two long, bent, acute spines directed backwards above the base of the abdomen; the latter smooth, shining, and globose.

Hab. Ceram.

The abdomen globose; the node of the peduncle with two long acute spines, which are divergent and curve backwards to the shape of the base of the abdomen.

Hab. Waigiou.

This species may very probably prove to be the worker of Polyrhachis Xiphias.

Female. Length 3 lines. Black; the head and thorax finely rugose and subopake; the abdomen globose and shining; the extreme apex of the flagellum pale rufo-testaceous; the angles of the prothorax acute; the wings yellow, with the nervures pale testaceous; the node of the peduncle with three acute spines, erect, and of equal length; the abdomen slightly sericeous.

Hab. Mysol.

[page] 17

This is very distinct from P. trispinosus, which is much larger and has the anterior angles of the thorax rounded; the spines on the node of the peduncle are shorter, and the central one shorter than the others.

26. POLYRHACHIS NIGRICEPS. P. ferrugineus, nitidus, capite nigro; thorace spinis duabus acutis antice et postice armato.

Worker. Length 3½ lines. Black; the head and thorax finely sha-greened; the mandibles ferruginous, but obscure, finely striated; the flagellum fusco-ferruginous; the extreme base of the scape bright ferruginous. Thorax oblong, narrowed behind, flattened above and at the sides, the lateral margins raised, particularly those of the prothorax in front; the metathorax has two long, slightly bent, acute spines directed backwards over the node of the peduncle, which has also two acute spines directed backwards; the legs ferruginous. Abdomen globose, smooth and shining, with a fine silky fulvous pile which changes colour in different lights.
