nearer to 4 than to 6 at base ; 2 always arising nearer to 3 than 

 to base of wing but variable ; discocellulars moderately oblique. 



Mid tibiae with promi- 

 f^/:4f y/^y"^^ r^ nent spines. Stigma of 



male in its most com- 

 plex form made up of 

 an outer oblique black 

 line, a black dash from 

 end of cell to vein 2 

 and a black spot above 

 the basal third of vein 

 1, the enclosed space 

 filled with gray scales, 

 and the entire stigma 

 followed by a patch of 

 raised gray scales. In 

 many of the species the 

 stignia is much sim- 

 pler. Fig. 25. 



I believe that the ac- 

 tion of Barnes and Mc- 

 Dunnough with refer- 

 ence to this group of 

 species (Contributions 

 III, 130) is the best 

 possible treatment. It 

 may be possible to split 

 ■M Limochores but I 

 find such a complete 

 transition in the structures that I hesitate to do so. I place venia 

 here because its relation to manataaqua seems to me much closer 

 than with the species of Atrytonopsis, where Barnes and McDun- 

 nough place it. The gentitalia of the male are closer to deva, but 

 those of the two genera are of a very similar type. The apiculus 

 of the antennae is usually longer than in Polites, but I have found 

 it variable, and in some specimens fairly short.

 pale spots, never sharply bent opposite cell nor with spot at this point
