Coleocerus crassipes Champion 1911

Subovate, convex, black; variegated with a dense clothing of rather large, imbricate, pale brown, fuscous, and whitish scales, the last-named condensed on the prothorax into a faint median line and a curved submarginal stripe, and those on the elytra into two transverse patches or fasciæ on the outer part of the disc and various irregular partly confluent smaller spots; the surface also set with minute, scattered, curled, decumbent setæ. Rostrum broad, depressed down the middle, and with a small bare fovea behind the nasal plate. Prothorax transverse, much broader at the base than at the apex, the hind angles subrectangular as seen from above and immarginate externally, the base bisinuate, the surface densely punctate. Scutellum small, transverse. Elytra oblong, not or very little wider than the prothorax; punctate-striate, the interstices feebly convex. Mesosternal protuberance small, conical. Legs stout.
 
Length 3 9/10—5, breadth 2—2 1/3 millim.

Hab.MEXICO, Acapulco (Höge; Knab, in U. S. Nat. Mus.).

Six specimens. Extremely like C. rotundicollis, and only differing from it in the much less rounded sides of the prothorax and the more oblong elytra. It is possible they are the sexual complements of the same species, but this is not likely to be the case. The less excavate, non-sulcate rostrum and the feebly protuberant mesosternum separate C. crassipes from all the varieties of C. variegatus and C. setosus.
