Head with epistome feebly gibbous on disc, rather dually, somewhat irregularly punctured posteriorly on sides; clypeus subtruncate anteriorly, round at sides, thinly bordered, edge upturned and very shortly sparsely bristled; genae round, near imperceptibly ciliate, not protruding from the eyes; frontal suture finely impressed, sometimes almostobsolete; front dually, irregularly, rather densely and more coarsely punctured than epistome. Pronotum transverse, moderately convex, dually punctured; large punctures four to five times larger than small ones, irregularly not closely scattered on sides; small fine punctures scattered throughout, sparser and finer on disc; lateral margins feebly arcuate, thinly bordered, edge glabrous; hind angles obtusely round; base faintly bisinuate. Scutellum elongate, punctured on basal third. Elytra oval, superficially microreticulate, thus subshiny; striae fine, uniformly, moderately impressed, distinctly punctured, subcrenulate; interstriae moderately convex and weakly microreticulate on disc, very finely sparsely punctured, on preapical declivity flat and distinctly microreticulate thus almost dull. Hind tibiae superior apical spur shorter than first tarsal segment; latter longer than following three combined. Male: fore tibiae apical spur somewhat stouter; head and pronotum less densely and less coarsely punctured; aedeagus Fig. 148-149. Female: fore tibiae apical spur somewhat more slender; head and pronotum more densely and more coarsely punctured.
