The difference between the puncturation of the clypeus and of 

 the rest of the head is very noticeable. There is an obscure 

 longitudinal depression on either side between the eyes. The 

 head behind the clypeal suture is punctured very similarly to the 

 prothorax, rather coarsely and deeply but not very closely. The 

 prothorax is decidedly transverse by measurement, but to the eye 

 only very slightly so, its front margin decidedly narrower than its 

 base ; its puncturation (especially when viewed obliquely from 

 the side) seems to rua in longitudinal wrinkles ; two transverse 

 depressions run from one lateral margin to the other, dividing the 

 surface into three nearly equal spaces ; a transverse depression 

 also runs obliquely from just within the posterior angle on either 

 side to the front margin, so that the entire surface is divided by 

 these four depressions into nine spaces, of which the three down 

 the middle are much larger than the rest; the sides are moderately 

 arched, their greatest divergence from each other being behind 

 the middle, where they are angulated rather than regularly 

 I'ounded ; the anterior corners of the prothorax ai"e rectangular, 

 and not at all produced forward ; the basal angles are similar, but 

 perhaps a trifle sharper. The elytra are finely and closely, but 

 very distinctly, punctulate-striate, and furnished with fine and 

 obscure pubescence which runs in rows along the striae ; the 

 intei\stices are flat or nearly so, and do not show any defined 

 puncturation under a Coddington lens ; the striae fail near the 

 apex, but the puncturation continues of even intensity, though it 

 becomes somewhat confused. 



The underside is opaque and minutely coriaceous, the hind body 

 covered with minute obscure pubescence. If 1 have both sexes 

 the sexual differences are slight. The basal four ventral segments 

 are short and equal, the fifth much longer. The latter is 

 traversed by a very fine arched keel which commences on either 

 side of the apex, and runs backward in a curve so as almost to
