 stigma oval, brown ; veins pale brown. V^enation : Sci and 

 Sc.2 subequal, endiug just beyond the fork of Ks ; R2 strongly 

 angulated at origin ; cell Mi onlv al)out one-half its petiole; 

 basal deflection of Cui from one-third to one-half the length 

 of cell 1st Mo- 



Abdominal tergites dark brown, the sclerltes a little paler 

 jipically. Sternites obscure yellow with a large brown blotch 

 at the lateral margin of each sclerite. Male hypopygium of

 pleurites not produced into conspicuous lobes at the raesal 

 apical angle and the eighth sternite without a chitinized 

 comb. Outer pleural appendage black, the mesal face 

 densely set with erect setfe which pass into spines near the 

 distal end, the margin before the apex with a powerful 

 chitinized spine ; inner pleural appendage pale.

 Sc.2 at the tip of Sc^ and equal to it ; Rs arcuated ; cell R<2 

 pointed at base ; r very faint, without macrotrichiae, near 

 mid-distance between the fork of i?2+3 ^^i^ the tip of 1\\ ; 

 cell Ml very small, about one-third the length of its petiole ; 

 cell 1st M2 likewise small, the basal deflection of Cui near 

 the middle of its length.
