Rostrum about as loxxg as head and px'othox'ax, separated from head by a deep dorsal incision, slightly curved, gena? scarcely dilated, so that the sides ax-e subparallel throughout. Upper surface with a central furrow which is narrow at base and broader and shallower anteriorly, the adjoining costa? indistinctly granulate; lateral sulci subequal, broad and deep, filled with lax-ge white scales and separated by a sharp carina, the upper pair meeting at base; scrobes directed bexxeath base of rostrum ; inferior basal furrow broad and deep. Antennce with scape scarcely reaching eye ; the two basal joints of funicle subequal.

Upper surface convex moderately closely set with small rounded tubercles, leaving a narrow and very indistinct central furrow without any carina • tubercles bare, each with a minute depressed seta; interstices densely clothed with large round white scales. Elytra broadly oblongo-ovate, shoulders very prominent and subrectangular, sides subparallel to well beyond middle, apical processes absent.
