Antennae extending below humeri, pale. Prothorax about a third wider than long, not as wide as elytra, with only slightly rounded sides and conspicuous tooth at each angle, shining, deep reddish brown often with deeper brown areas on each side, and with fine, not dense punctures especially on sides, intermediate median line often impunctate. Scutellum reddish brown. Elytra approximately three times as long as prothorax, convex with only trace of intrahumeral depression or depression below, striate punctures not deeply impressed or very dense and becoming faint over basal callosity, along sides, and after the middle, side rows only half as long as usual; shining pale yellowish brown with sutural edges often reddish brown.
