Similar in size and form to C. perscillus, but only thinly clothed with hair-like white scales on the upper surface, intermixed with oval scales on the under surface. Beak as long as the head and prothorax, slender, abruptly curved near the base, then nearly straight, shining, smooth, sparsely punctured near the base, frontal constriction very feeble; head convex, sparsely punctured. Prothorax wider than long, sides oblique, very slightly rounded, tip feebly constricted; disc densely punctured, scales directed transversely; base bisinuate, scutellar lobe rather large, truncate. Elytra somewhat wider than the prothorax, narrowed behind from the humeri, separately (though very slightly so) rounded at the tips; pygidium not exposed; striae deep and broad, interspaces flat, densely punctured, each with two rather regular rows of hair-like scales. Prosternum not very wide between the coxae, hind margin truncate in front of the mesosternum, not at all emarginate; side pieces of metathorax wide; fifth ventral longer than the fourth; antennae with the first joint of the funicle long and slender, second two-thirds as long, equal to the third and fourth united.
Length 3.0 mm.; 0.12 inch.
♂Prosternum broadly and feebly concave; horns reduced to a small slender cusp; ventral surface flattened, fifth segment as long as the third and fourth united.
♀Prosternum slightly convex, without horns; ventral surface convex, fifth segment a little longer than the fourth
