 second vein bent upward, but its inner angle at end less than a right 

 angle; second submarginal large, including apex of wing; first 

 posterior widely open.

 Length about 6 mm.; wing 4! mm.; head apparently pale, no

Upper end of anterior cross-vein to basal corner of second sub- 

 marginal cell 1,600 



Lower end of anterior cross-vein to apex of discal cell 800 



Lower end of anterior cross- vein to base of discal cell 272 



Second basal cell on discal 192 



Second basal cell on fourth posterior 160 



The vein separating the dis- 

 cal cell from the third posterior 

 shows a single uniform gentle 

 curve.
