Elongate, black, not very densely covered with elongate cinereous scales; beak densely finely punctured, separated from the front by a feeble transverse impression; head punctured; prothorax more deeply and coarsely punctured; elytra densely punctured, with slight traces of striae near the margin and tip ; front thighs strongly toothed; antennae brown, with verticellate rows of white scales.
Length 2.7 mm.; 0.10 inch.
Texas, Belfrage; Santa Barbara and Warner's Ranch, California, Crotch.
When the scales are rubbed off a fine inconspicuous pubescence remains. The emargination of the prosternum gives an appearance of feeble postocular lobes, and in following Lacordaire's arrangement this genus would be placed in the Ceratopides, after Acanthobrachium, from which it seems to differ by having only the front thighs toothed.
