Identification
"Color varying from yellowish brown to piceous, often uniform, but more commonly piceous brown, with the elytra (except the suture), antennae and legs paler. Form moderately stout and convex; pubescence cinereous, rather long and conspicuous, the hairs of the elytral intervals shorter and more inclined. Head about 4/5ths as wide as the prothorax, strongly but sparsely punctate; tempora parallel, their length fully 1/4 that of the eye as seen from above. Antennae reaching the hind margin of the prothorax, the joints all longer than wide. Prothorax convex, a little wider than long, widest before the middle; sides rater strongly rounded, narrowed behind, margin finely serrate; surface moderately strongly punctate, the punctures separated by fully their own diameters; posterior fovea small and not deeply impressed. Elytra elongate-oval, convex, striae distinctly impressed; intervals slightly convex, their punctures decidedly finer than those of the striae. Beneath coarsely, rather closely punctate, more finely and sparsely along the median line; the first ventral more finely and sparsely than the metasternum, the following segments finely punctate. Metasternum subequal to the 1st ventral; middle coxae narrowly separated about 1/6 their own diameter, legs short." transcribed by C.Wood from Fall, 1899.
