 The prothorax is about half again as wide as long, strongly 

 convex, and even above; at its widest behind the middle, the 

 sides strongly rounded, the front (which is rather strongly 

 emarginate, with sharp angles) considerably narrower than the 

 base, the hind angles obtuse, but not rounded ; the base moder- 

 ately and widely lobed in the middle. The elytra are at their 

 widest near the apex, where they are about a quarter wider than 

 the prothorax ; they are evidently wider at their base than the 

 base(but not than the widest part) of the prothorax ; the set.e of 

 the elytra run in rows, tlie iiitei'stices being tr'ansversely 

 rugulose.
