Show 278 MR. R. SnELFORD ON MIMETIC INSECTS AND [Nov. 4, open behind. Mesosternum much broader than the prosternum ; acetabula of middle coxae open to the epimera. Metathoracic episterna rather broad in front, narrowed behind. Femora pedunculate at base, gradually thickened into a fusiform club towards the distal end. Hind legs much longer than either of the anterior pairs ; first joint of hind tarsi longer than the three succeeding joints together. Abdomen normal, its intercoxal process rather broad, and obtuse in front. _ ^ This genus, which I was at first inclined to refer to Lacordaire's group Psebiince, seems to me, on fuller consideration of its characters, to be better placed in the Necydalince, although it differs from other members of this group in having no anterior prolongation of the head, the front from the interantennary ridge to the clypeal suture being relatively very short, and the clypeus scarcely broader than the labium. The Psebiince have certain characters, wanting to the present genus, which point to an affinity with the Auxesince and Methiince, and, through those groups, with the (Eviinaz. P sebena brevipennis, sp. n. (Plate X IX . fig. 12, $ .) Capite, prothorace, elytris ad basin, articulo primo antennarum et pedibus quatuor anterioribus rufo-testaceis; metasterno medio testaceo, lateraliter fu sc o ; abdomine medio et pedun-culis femorum posticorvm pallide testaceis; ceteris nigro-fuscis aut nigris. Long. 1 3 -1 6 mm. Hab. Kuching in Sarawak, Sept. 29 and Dec. 4, 1 89 9. Two female examples ; in British Museum and Hope Collection, Oxford. Head, prothorax, first joint of the antennae, the four anterior legs, and the base of the elytra testaceous red. Metasternum testaceous in the middle, dark brown at the sides. Abdomen pale testaceous along the ventral surface from the base to the last segment, this segment and the lateral borders being, like the upper side, brownish black. Hind legs also black, with the femoral stalks pale testaceous or nearly white. The head and prothorax are covered with a very faint reddish pubescence, but the prothorax has two slightly raised areas on each side bare of pubescence. The inner portion of each elytron near the base is very closely punctulate and covered with a faint pubescence, the outer and apical parts being sparsely punctulate and more glossy. 3.
