Black, densely clothed with small gray scales, which are narrower but not hair-like upon the upper surface. Beak as long as the head and prothorax, slender, curved, opaque, smooth, slightly punctured and pubescent near the base; head feebly punctulate. Prothorax not wider than long, rapidly narrowed from the base, strongly rounded on the sides, very strongly tubularly constricted near the tip, bisinuate at base; scutellar lobe slightly emarginate; surface densely rather finely punctured, scales not directed transversely; dorsal line smooth, slightly elevated. Elytra conjointly rounded at tip, pygidium slightly visible (only in male?); striae deep but not broad, interspaces flat, densely punctured; suture and alternate spaces clothed with paler scales. Antennae with the second joint of funicle two-thirds as long as the first. Side pieces of metasternum wide; fifth ventral nearly as long as third and fourth united. Hind margin of prothorax beneath narrowly emarginate.
Length 6.2 mm.; 0.25 inch.
♂ Prosternum with a very deep excavation in front of the coxae, and armed each side of the cavity with a long curved horn:♀ wanting.
Missouri, one specimen. This is the largest species in our fauna, and corresponds in size with C. pistor and dilectus; I do not feel disposed however, to refer it to either of them.
