 Keys to the Venational Divisions and Genera of Group I 



Hind wing with vein 3 appreciably before the outer angle of cell ; cell less than one-half the 



wing length Venational division A 



Cryptoblabes (p. 10) 



Hind wing with vein 3 closely approxinaate to or from the angle of the cell (rarely shortly 

 stalked with 4-5) ; 7 and 8 approximate, contiguous, or shortly and weakly anastomosed 

 beyond cell; cell at lower angle nearly half as long as wing; if shorter, then vein 3 of 

 moderate length and the free (divergent) part of 3 decidedly shorter than vein 2. If 

 vein 3 sometimes appreciably before outer angle of cell (Acrobasis), then cell one-half 

 the wing length Venational division B (key, p. 2) 



Hind wing with vein 3 closely approximate to or from the angle of cell; veins 7-8 solidly 

 anastomosed beyond cell for at least three-fourths of their lengths.
