 femoral bases narrowly obscure yellow. Wings whitish sub-

 the base of 27id R^ ; in the female, the stigma is smaller, but 

 still much larger than '\nD. speruta ; wing-tip broadly infus-

 cell M, Cui, and a large space beyond the stigma whitish sub- 

 liyaline; Ming-base narrowly yellowish; veins dark brown. 

 A' euation : Sci ending opposite or beyond mid-length of lis ; 

 r very long and arcuated ; cell 1st ilYg open by the atrophy 

 of the outer deflection of M3 : basal deflection of Cui a little 

 less than its own length beyond the fork of M. 



Abdomen dark brown, the sternites greyish pruinose. 

 Alale hypopygium reddish brown, the fleshy lobe on the 

 ventral face of each pleurite a little stouter than in sperata ;

 paler brown. Halteres dark, the knobs pale. Legs pale, 

 the tibiae and metatarsi tipped with darker. Wings tinged
