jecting much beyond the epipygium. Black; a spot on each side 

 of the vertex, tegulse, femora, tibiae and tarsi ferruginous, an

Q. Head suborbicular, slightly convex above, shining; pro-

 anterior nearly to the posterior margin, anterior angles produced 

 into blunt spines; sparsely punctured. Median segment very 

 short, obliquely truncate posteriorly, finely punctured. Abdomen 

 shining, very sparsely punctured; first segment depressed on the 

 apical margin, leaving a transverse carina just before the apex; 

 second segment with three prominent transverse carina? and the 

 apical margin slightly recurved, forming a fourth less prominent 

 carina; third segment with an impressed transverse line near 

 the base; pygidium oblique, rather narrow, the sides nearly 

 parallel, narrowly rounded at the apex. Tarsal ungues simple.

I have not seen this species. It is evidently closely allied to

 sufficient to justify separation.
