 uncolored elongate-oval fossa widening posteriorly;

Prothorax quadrangular, with slightly convex, lateral 

 and posterior margins; posterior angles with one small

 through. Metathorax in outline a semicircle with 

 anterior curving part slightly flattened and posterior 

 margin slightly convex; posterior angles with three long 

 pustulated hairs and three shorter, weaker, non-pustu- 

 lated ones; one of the long hairs is in the apex of the 

 angle, the other hairs are ranged along the posterior
