Show 1900.] FROM SOUTH AND CENTRAL AFRICA. 227 of short hairs ; legs fulvous ; all the femora armed with a small tooth. Hab. Kamozi, T u m b u (J. Duvivier). (Coll. Belgian Mus. and m y own.) Unlike tbe other two or three species of the genus, the present one has armed femora, but agrees in all other details: this and the colour of the legs will easily distinguish the species. CORYNODES NIGRIPENNIS, Sp. n. Bluish black, the head and thorax rufous, the latter very finely and subremotely punctured; elytra black, opaque, very closely and finely rugosely punctured, the claws appendiculate. Leugth 11 millim. Of subcylindrical, parallel shape ; the head impunctate, rufous, shining ; the clypeus triangular, deeply separated from the face by a transverse, medially interrupted groove; antennae nearly extending to the middle of the elytra, black, the second and third joints fulvous below, the terminal six joints strongly flattened ; thorax of the same shape as in the preceding species, rufous, very shining, extremely minutely and sparingly punctured, the extreme anterior and basal margins black; scutellum fulvous, margined with black ; elytra closely and somewhat strongly punctured, black, the interstices finely rugose, the extreme apex with a small obsolete fulvous spot; below and the legs bluish black, the anterior tibiae strongly curved at the apex. Hab. Cameroons. This species, of which I have received a single specimen from Herr Bang-Haas, agrees so closely in structural characters with the following, that I a m almost tempted to look at it as an extreme variety of tbe latter; but the coloration of the head, thorax, aud that of the elytra (unique amongst the numerous members of the genus) is so entirely different, that, in the absence of intermediate forms, I must consider the two insects distinct. CORYNODES BIMACULICOLLIS, Sp. n. Bluish black below, as well as the legs and antennae, above fulvous : thorax impunctate, the anterior and basal margins and two elongate spots on the disc black ; elytra very closely punctured, claws appendiculate. Length 11 millim. Head impunctate, fulvous, a small spot at the vertex and the supra-ocular sulci black; clypeus separated from the face by a deep transverse groove; antennae black, the lower two joints fulvous, the apical five joints gradually and broadly flattened ; thorax about one half broader than long, narrowed anteriorly, the sides straight, the surface impunctate, the extreme anterior and basal margins black, the disc with two large, oblique, elongate black spots ; scutellum fulvous, margined with black; elytra evenly, closely, and distinctly punctured, the interstices slightly wrinkled here and there; anterior tibiae strongly curved at the apex. |
