 part, very broad on the vertex, the genae being as long behind the 

 eyes as the eyes themselves, and the outer angles are only slightly 

 rounded, thus making the base somewhat straight ; antennae robust, 

 third joint half the length of the fourth ; pronotum strongly sloping 

 laterally, rnesonotum moderately convex, scutellum not very convex 

 but with an acute lamelliform process projecting behind as an 

 horizontal spinose process on each side ; metanotum gradually 

 attenuate from the median lateral part and rounded at apex ; 

 surface foveate striolate, but broadly reticulate on the metanotum, 

 which is sparingly villose white, whereas the pronotum and 

 mosonotum are briefly villose black ; abdomen sessile, clothed with
