Thorax one-half wider than long, sides straight and parallel to middle, thence rounded to apex, which is truncate and one-half the width of base; surface, as well as that of elytra, densely and finely punctured. Elytra with two or three feebly impressed striae near the suture, these more strongly marked near apex.
