Pronotum of the S as broadas the elytra, with its sides nearly parallel froui the slightly projectingfront angles up to the lateral angles placed a little behindthe middle, thence converging obliquely to the base ; the frontmargin somewhat bowed backwards in the middle ; the baserounded in the middle, sinuate towards the sides ; disk feeblyconvex, with a large, sparsely punctate, smooth area, roughlyoctagonal in shape, over the whole of the central part, the spacesbetween this and the lateral edges are very finely and closelypunctate and opaque ;pronotum of $ with its sides some« hatconvergent in front from the prominent lateral angles, stronglypunctured near the sides. Elytra somewhat flattened above,broadly rounded at the apex, tlie sides narrow, nearl}* A'ertical,with an obtuse costa running between each and the disk. Episternaof metathorax nearly parallel-sided, narrowed a little nearthe apex, which is straightly truncate. Legs rather short ; femoraflattened fusiform ; the hind pair extended but little beyond thesecond abdominal segment ; tarsi relatively short, with the firstjoint scarcely longer than the second.
