the tip, where it ends in two minute points. Legs : coxae and 

 femora pale yellowish, tibiae and tarsi pale blackish. Wings pale 

 grey. The 3rd longitudinal vein considerably bent down on the 

 distal portion, ending at or just above the tip of the wing. 

 Halteres yellowish. 



Length 3 millim. 



Described from one male (type) from Tonglu, Dar jiling District, 

 10,000 ft,, 22. iv. 10, taken by Mr..C. W. Beebe; also from a 

 second male taken by me at Darjiling, 7000 ft., 29. viii. 10. 



Type in the Indian Museum. 



An additional male has a wholly blackish dorsum to the 

 abdomen, and the genitalia, though too contracted to be properly 

 visible, appear to be similar ; some finger-like appendages at least 

 being visible. It is in the Indian Museum collection, taken by 

 Dr. Armandale at Kurseong, 22. vi. 10. Though possibly distinct 

 the three specimens appear to represent but one rather variable 

 species.
