 exterior margin oblique, straight, posterior angle convex ; cell two-thirds the length ; 

 first subcostal emitted at one-fourth before end of the cell, joined to the costal 

 before reaching above end of the cell ; second from near end of the cell, trifid, fifth 

 from the end ; discocellular extremely slender, slightly concave in the middle, bent 

 near the ends, radials from the angles ; middle median at one-eighth before end of 

 cell, lower at one-third ; submedian straight: hindwiug rather long, narrow, ajjex
