Long. corp. lin. 14; capitis, 3; prothor. 3; lat. 3; elytr. long. 8, lat. 4. Hab. in Guinea. In mus. nostr. Comm. Dom. Raddon. The insect is black, except the elytra and abdomen, which are pitchy; the head is punctured, the disc being more sparingly so than the clypeus and hind part; the mandibles are toothed as in the preceding species, and the head similarly channeled; the space between the eyes is however rather more elevated, with a circular shallow impression in the middle. The maxillary palpi are rather more securiform than in the preceding, and the labium has a tubercle between the base of the labial palpi; its anterior margin is also produced in the middle into a small point. The antennae are not longer than the head, with the terminal joints considerably dilated and transverse, the last one being nearly quadrate, with the outer angle rounded. The prothorax is quadrate, or rather slightly broader behind than in front, very glabrous and margined, the anterior angles not so prominent as in the preceding, but the posterior angles similarly subemarginate: each of the elytra is marked with nine punctated striae; the 3rd and 4th, 5th and 6th, 7th and 8th striae being confluent together before the tip, the 5th and 6th not extending so far as the confluence of two on either side. The femora are similar to those of the preceding, except that the subapical angular projections of the hind ones are smaller, the anterior tibiae are more curved, and the dilatation at the tip on the outside more sudden; the middle tibiae are also rather more curved and slightly dilated, and the ...
