Although I am now only able to include eight genera in this group, such au 

 enumeration gives but little idea of its generic strength, as it is widely and probably 

 universally distributed.

Anterior wings subtriangular ; costal margin arched and slightly convex, outer margin moderately 

 convex and sometimes slightly waved, inner margin somewhat concavely sinuate ; costal nervure extending 

 to a little beyond middle of costal margin ; first subcostal nervule short, emitted a little beyond half of cell 

 ami anastomosed with costal nervure, second emitted close to base of first, third from a little before end of
