HESPERIOIDEA OF AMERICA 63 



Secondaries rounded, slightly lobed at anal angle. Wings more 

 elongate in female. Primaries of male with a slender, longi- 

 tudinal stigma. Cell of primaries about three-fifths as long as 

 wing; vein 5 arising much nearer to 4 than to 6. Fig. 21.

I cannot agree with Dr. Skinner that this and the following are but one 

 species, but as he suggests, rayata may fall before the female of procris, 

 in which case the latter name might be restricted to the female type and 

 retained as a species. 



2. COPAEODES RAYATA

San Benito, Texas; June and July. 



I have seen the types of this species and it is abundantly distinct from 

 aurantiaca. The pale ray is variably distinct, but the veins are darker 

 than the ground color and of a somewhat rusty shade on the lower surface 

 of the secondaries. The size is smaller than aurantiaca. 



GROUP C 



Key to the genera 



1. Club of antennae blunt or with a rudiment of the apiculus 



Chaerephon 



Club of antennae with a sharp apiculus, sometimes very- 

 short 2 



2. Vein 5 of primaries well curved toward base, arising con- 

 spicuously nearer to 4 than to 6 3 



Vein 5 but slightly curved, only a little nearer to vein 4 at 

 base ; L. D. C. weak 11
