 surface (and on the tibiae) are very pale yellow. Head flat- 

 tened, thickly rugulose. Thorax thickly and rugosely j)unc- 

 tured, convex, the base on each side oblique. Elytra gently 

 convex, a trifle broader towards the aj)ex, which is not very 

 obtusely rounded, slightly shining, crcnatc-striate, the inter-
