with a sharp posterior ridge on each side adjoining the eye, 

 the two ridges converging to the front, Avhere they end abruptly 

 at a distance from the margin. The canthus is rounded and 

 rather obtusely angulate behind. The pronotum is very 

 deeply, coarsely and confluently punctured, the punctures 

 distinct in the middle but comjjletely obliterated at the sides. 

 There is a broad longitudinal median depression. The front 

 angles are rounded, the lateral margins entirely serrate and 

 almost straight to beyond the middle, where there is a very 

 blunt angle, and feebly sinuate to the hind angle, which is very 

 obtuse. The base is very gently rounded. There is no 

 scutellum. The elytra bear rows of closely contiguous punctures, 

 separated by rows of minute elevated granules, those of the 

 alternate rows uniting to form ridges in the anterior part. The 

 sutural margms are also elevated and fonn shining ridges. The 

 menturn and the prosternmn are very strongly punctured, the 

 metasterm(m. is densely rugose at the sides and densely and 

 coarsely punctured in the middle, and the abdomen is very 

 strongly and rather closely punctured.
