basal segments of the abdomen are shining, closely, distinctly, 

 but not strongly, punctured ; their basal furrows are covered 

 with white pubescence ; the basal part of the last segment is 

 minutely, but not very closely, punctured ; the narrowed apical 

 part is closely rugosely punctured ; in its centre is a smooth 

 narrow keel. The last ventral segment is long, narrow, acutely 

 pointed and projects over the dorsal. 



There is a distinct furrow on the front ; the lateral teeth 

 on the scutellum distinctly project beyond the middle of the 

 apex ; the ventral surface of the abdomen is more strongly and 

 closely punctured than the dorsal ; the transverse median 

 nervure is received shortly, but distinctly, behind the transverse 

 basal. The last dorsal segment is distinctly depressed laterally 

 at the base of the narrowed part. The second transverse cubi- 

 tal nervure is received shortly behind the middle of the radius ; 

 the nervures and stigma deep black.
