Reddish fulvous; the antennae (the basal joints excepted), the knees, apex of the tibiae, and the tarsi black ; thorax very sparingly punctured ; elytra finely punctate-striate. Length 3 lines. Head with a few fine punctures ; the epistome broad, subquadrate, scarcely separated from the front ; mandibles black; antennae slender, filiform, the lower three joints fulvous, the rest black, the fourth joint slightly longer than the third; thorax about one half broader than long, the sides rounded, the anterior margin straight, the surface rather convex, with a few fine punctures ; elytra much broader at the base than the thorax, without basal depression, very finely punctate-striate, fulvous and shining like the rest of the upper surface; underside coloured as above ; the knees, the apex of the tibiae, and the tarsi black. A single specimen is contained in m y collection. NlSOTRA NIGRITARSIS, n. Sp.
