as lon<; as the third and fbiirtli joints combined, third joint 

 a little broader at the apex than lonj:;. Ocelli in a broad 

 trianijle, the posterior pair fully half as far again from each 

 other as from the eyes. I'ronotum as broad as the meso- 

 notum, smooth and shining, the mcsonotum shining, with 

 large and rather sparse punctures ; scutellum and i)ost- 

 srntclliim shining, the former with a few small punctures. 

 Tergitcs sliining, rather closely covered with large and very 

 deep punctures, on the fourth tergite the punctures become 

 sparser and shallow at the apex, those on the fifth tergite 

 are small and scattered, sixtii tergite almost smooth ; 

 stcrnites shallowly and sparsely jmnctiu'cd. Median seg- 

 ment finely and closely punctured ; the basal triangular 

 area large, covering almost all the dorsal surface, smooth 

 and shining with a well-marked median sulcus and without 

 marginal carinse. Cubitus of the liind wing interstitial 

 with tiie transverse median nervure, the fore wings with a 

 small fuscous cloud at the extreme apex.
