margined ; dorsulum convex, its punctures larger than those of 

 head and distinctly separated ; scutellum similarly punctured, the 

 mesopleurse a little less strongly so ; upper and posterior surfaces of

 on the sides with large punctures, similar to those on the fourth dor- 

 sal segment, below the ridge, the punctures finer, closer and evener ;

 sutures, the apical segment suddenly constricted and drawn out into 

 a point apically, the first, second and third segments punctured 

 about like the dorsulum, the remaining dorsals decidedly more finely 

 punctured ; the ventrals are punctured like the first dorsal, the
