The head is arched downwards; the median impression is rather broad in front, 

 narrowed on the vertex. The thorax has the median impression very deep, broadest 

 immediately above the base, narrowed in front, scarcely extended to the front margin ; 

 there is a swelling at the posterior angles, with a slight impression behind it at 

 the base ; the punctures on the disc are generally a little separated from each other 

 (fig. 4). The elytra have the subcosta moderately well marked ; each has two slightly 

 elongate-ovate spots in the sutural area, one at one third from the base and the other 

 at one third from the apex ; halfway between these, but outside the subcosta, a very 

 small spot may be traced. The prosternal chin-piece is very short, deeply emarginate ; 

 the prosternum is not very strongly nor closely punctured, and not pubescent ; the inter- 

 coxal process is slightly convex in the middle, gently impressed at the sides and apex, the 

 apex obliquely and arcuately narrowed. The epipleura are finely and moderately closely 

 punctured, slightly pubescent on the outer half. The abdomen is very finely punc- 

 tured ; the lateral carina of the basal segment is distinctly curved and slightly angular 

 in the middle and curved at the apex, with a yellowish spot above each curve (fig. 4 a) ; 

 the second and third segments have similar spots.

Elongatus, seneus, nitidus, capitis vertice thoracisque disco cupreis ; capite tenuiter punctato, antice profunde

 sat crebre punctatis, apice denticulato.

The head is very much inclined, finely and moderately closely punctured. The 

 thorax is rather finely punctured, the punctures distinctly separated from each other ; 

 in the middle of the base there is a deep, round, smooth impression, not quite reaching 

 to the middle of the disc ; there is a swelling at the posterior angles. The elytra are 

 nearly black, rather strongly punctured with cuneiform punctures, which are slightly 

 separated from each other, but sometimes touch in a transverse direction ; the subcosta 

 is fairly well marked ; the apex of each elytron is rounded and finely denticulate. The 

 prosternal chin-piece is very slightly sinuate, almost straight. The prosternum is mode- 

 rately strongly and not very closely punctured ; the intercoxal process with slightly 

 thickened margins, obliquely narrowed at the apex. The episterna are moderately 

 closely punctured, with a little pubescence on the outer side. The abdomen is finely
