Pronotum transverse, convex, dually punctured; large punctures, three to four times larger than small ones, rather sparsely irregularly scattered on sides, lacking medially; small punctures almost evenly scattered throughout but somewhat deeper laterally and more superficial medially, lacking on a narrow longitudinal medio-basal areola; lateral margins feebly arcuate, very thinly bordered, edge glabrous; hind angles obtusely round; base regularly arcuate, not bordered. Scutellum flat, elongate, very finely sparselypunctured on basal half. Elytra ovalelongate, feebly broadened posteriorly, very convex, finely striate; striae superficially, not closely punctured, faintly crenulate; interstriae almost flat, superficially alutaceous, near imperceptibly sparsely punctured.
