172 CATALOGUE OF DIPTERA 



culated style : the segments are darker in the middle : face and 

 legs paler : wings yello^vish, the tip and transverse nervure 

 surrounded with brown. 

 The first longitudinal nervure in this genus is distinctly doubled, 

 though the branches are generally very near each other : in general 

 character it seems rather related to Psila or to Palloptera than to 

 any of the genera near which it stands in Meigen.
