3. Heptacondylus carinatus .

H. obscure fusco-ferrugineus; capite thoraceque carinis irregularibus abbreviatis; metathorace spinis duabus longis armato.

Worker. Length 2 1/2 lines. Dark fusco-ferruginous, closely resembling H. subcarinatus , but with thicker antennae, and the joints shorter, the scape distinctly shorter and not so slender at the base; the head proportionably larger and much more strongly carinated; the thorax roughly carinated, and having longer and stouter spines; in other. respects agreeing with H. subcarinatus .

Hab. Borneo (Sarawak).

This may possibly be a form of H. subcarinatus , but the various differences pointed out appear to characterize a distinct species.

The insect which I am about to describe, although evidently belonging to the Poneridae, is of such a different and remarkable form, to any insect belonging to any of the sections of the genus Ponera , or any of the subgenera, that I propose to constitute a new genus for its reception; the abdomen of this singular species is formed, as it were, of three nodes, each being a little, longer and wider than the preceding.
