3. Antennae scarcely longer than width of thorax. .HylephUa 

 Antennae distinctly longer 4 



4. Mid tibiae with spines 5 



Mid tibiae without spines Atrytone 



5. Apiculus of antennae shorter than thickness of club or not 



abruptly constricted 6 



Apiculus at least equal to thickness of club, slender; either 

 abruptly constricted or distinctly longer than thickness of 

 club 9 



6. Primaries apically produced and secondaries lobed ; apiculus 



very short 7 



Primaries and secondaries moderate; apiculus usually mod- 

 erately long 8 



7. Male stigma slender; wings of female moderate. . . .Pamphila 

 Male stigma a large blotch ; wings of female similar to those 

 of male Atalopedes 



8. Vein 2 of primaries slightly nearer to base of wing than to 

 vein 3. Secondaries well marked with yellow fulvous; see 



description Augiades 



Vein 2 variably nearer to 3 ; when doubtful, secondaries with 

 little fulvous, at the most a transverse band; see descrip- 

 tion Polites 



Vein 2 immaterial. Club of antennae very stout, with a 

 fine apiculus, or moderate with a thick apiculus Poanes 



9. Apiculus slender, about twice thickness of club .... Oligoria 

 Apiculus shorter or thick 10 



10. Apiculus slender ; male stigma large, with large gray scales ; 



under surface fuscous Catia 



Apiculus tapered, not abruptly constricted; male without 



stigma ; under surface not fuscous Poanes 



Apiculus slender, variable, male stigma variable. Under 

 surface gray powdered to dark brown Atrytonopsis 



11. Male stigma large; maculation yellow Epiphyses 



Stigma not large; maculation not pale yellow 12 



12. Apiculus fine; shorter than thickness of club Lerodea 



Apiculus longer, or wings immaculate 13 



13. Third joint of palpi long (ex. nanno) ■ fringes checkered
