Narrowly elongate, black, the antennae fulvous, the head, thorax, aud legs flavous ; thorax impunctate, the sides rounded; elytra closely and finely punctured, black. Length 2\ millim. Head impunctate, strongly obliquely grooved above the eyes ; frontal elevations broad and flattened, apex of the clypeus between the antennae rather broad, palpi distinctly thickened ; antennae extending to the base of the elytra, entirely fulvous, all the joints, with the exception of the first, short, the terminal ones thickened; thorax one-half broader than long, the sides rounded, the angles distinct, very slightly thickened, the surface entirely impunctate; scutellum black, impunctate ; elytra slightly wider at the base than the thorax, very feebly depressed below the base and the scutellum, black, shiny, finely, closely, and evenly punctured ; legs rather robust, flavous ; breast and abdomen black ; the last abdominal segment with a round fovea ( o* ? ) ; prosternum very narrow, anterior coxal cavities open. Hab. West Africa. Closely allied to C. wollastoni Baly, but with the antennae entirely fulvous and the sides of the thorax rounded, not straight. JAMESONIA (THRYMNES) FEMORALIS, sp. n. (Plate XX. fig. 12.)
