Genus HYLEPHILA Billberg 

 Hylephila Billb., Enum. Ins. 81, 1820. Type Papilio phylaeus 



Drury. 

 Euthymus Scud., Syst. Rev. 56, (77), 1872. Type P. phylaeus 



Drury. 

 This genus closely resembles Pamphila in structure but dif- 

 fers in the very short antennae and the straighter stigma. The 

 female, as in Atalopedes, does not differ much in general struc- 

 ture from the male ; some are almost indistinguishable from 

 campestris, but they never have hyaline spots on the primaries. 

 We have but one species of Sylephila.
