 ulated, with eight divisions ; first long, almost cylindrical,

 length of the second, the latter cylindrical; eyes hairy; wings 

 long, all posterior cells open, anal cell closed before it reaches

Genotype, P. celmnospila Taylor. ^. Unknown. 



The genus may be distinguished from CcRuoprosopon by its 

 differently shaped palpi and antennae. In Falimmecomyia, the 

 first joint of the antennae is long, the second very short: while, 

 in CcBitoprosopoii, the first and second joints are short and stout. 

 From Elaphromyia, it may be separated by its different antennae, 

 palpi, and hairy eyes.
