Antennae short, terminating in a very short, subconical club. Head strongly and densely punctate. Prothorax about 2× as wide at the base as long, narrowed at the apex, rounded at the sides, finely bordered at the base, anterior margin slightly emarginate; anterior angles rounded; pronotal disc finely reticulate, somewhat less strongly punctate than head; between the marginal striae of the base and the border of this base a very fine line of punctures is present. Scutellar shield subpentagonal. Elytra conjointly about as long as wide, separately rounded at apices, little densely punctate, except the sutural striae; punctation often in rows. Pygidium sparsely punctate; against the base, a line of large, sunken punctures.
