Cells of the wings very short ; sub-costal nervure five- 

 branched, all the branches emitted beyond the end of the 

 cell ; first discoidal nervule emitted from the end of the cell ; 

 antennae short, slender, with a well-marked flattened club. 



Wings narrow, elongate-oval, thickly clothed with scales. 



This genus only includes a few species, much resembling 

 each other, and is confined to Europe and Northern and 

 Western Asia. It has a slight superficial resemblance to the 

 African and Indian genus to which Dr. Scudder correctly re- 

 stricts the name Leptosia, but this has much broader, shorter, 

 and rounder wings.
