Elongate, black or brown, covered uniformly with silvery-gray scales; prothorax longer than wide, sides feebly rounded, a little narrowed and broadly constricted near the tip, obscurely granulate. Elytra wider than the prothorax, humeral angles obtuse, almost rounded, striae fine, distinctly punctured. Antennas and legs testaceous, the latter long and slender, tibiae strongly hooked, curved and armed with a row of small distant teeth on the inner face. Tarsi longer than usual, joints 1-3 equal, fourth equal to the two preceding.

Length 4.0 mm.; 0.16 inch.


Middle States and Canada. I have adopted the name given in Dejean's Catalogue. Easily known by its large size and elongate form; there is a marked difference in the beak of the two sexes; that of the male is stout, shining, very finely punctulate, not longer than the prothorax, and about one-half as wide as the head; in the female it is slender, one-third longer, and with the antennae inserted about the middle of the length.
