80 MYCETOPHILIILE. 



apical half of the first three segments. Belly yellowish. Legs pale 

 yellowish, trochanters a little blackish ; tibiae and tarsi faintly 

 blackish. Wings pale grey, considerably iridescent ; venation 

 normal. . 



Length 3 millirn. 



Described from a single specimen in the Indian Museum from 

 Mundali, Jaunsa Divison, Dehra 'Dun District, 12. v. 10 (C. W. 

 Beebe). 



Apparently the example is a female ; the genitalia are much 

 withdrawn, but two small rounded pieces can be seen, which seem 

 to be terminal lamella?. Otherwise, if the specimen is a male the 

 genital organs differ in shape considerably from typical forms. 



Subfamily MYCETOPHILIN^E.
