straight carina, which continues across the metasternum until 

 it has passed the hind coxee ; at the mesosternal suture there 

 is a line of somewhat coarse punctures, in the metasternum 

 on each side close within the carina is a row of five or six small 

 foveas ; the suture again between the metasternum and first 

 segment of the abdomen is punctate, the segment itself being 

 finely punctulate on the surface ; all the tibias are dilated, ante- 

 rior pair obscurely dentate on the outer edge, posterior and 

 intermediate obtusely angulate before the bases.
