A large and robust species without markings. It is easily recognized by its nearly globose thorax and proportionally short and very convex elytra. Length from the anterior margin of the thorax to the apex of the elytra 14 mm, width of the middle of the elytra 6 mm. — The uppersurface of the smooth and shining narrowed portion of the rostrum is keeled at the base and provided with a few longitudinal rows of shallow punctures which however disappear beyond the middle; the dilated basal portion of the rostrum which is a little longer than wide at its base is incrusted ²) and shows a few small punctures and a longitudinally impressed line; the rostrum is separated from the forehead, which is similarly incrusted and punctured, by a transverse impression, the centre of which shows a punctiform fovea.
