 Venation (see fig. 6, plate III), Rs beyond the cross- vein r-m short, 

 a little shorter than r-m; R2, R3 and R4+5 all originate at a com- 

 mon point; R2 at origin is perpendicular; cross-vein m lacking; 

 basal deflection of Cui at fork of M. 



Abdomen: tergites light brownish yellow, with num.erous 

 slender black hairs; segment 2 with a short black sub-basal streak
