The differences between tliis insect and black specimens of F. erithalion are 

 very slight. A more exhaustive e.xploration of Nicaragua and Honduras may 

 possibly furnish material of specimens completely connecting P. e. sai/'/atfes with 

 F. poh/zelus. 



The differential characters of the two subspecies of F. polyzelus are highly 

 interesting. "We have mentioned under P. tertumnus that one of the subspecies 

 of that species has the tibiae of the male hairy, while they are simply spinose in 

 the other subspecies. In F.poli/zelus we meet with the same phenomenon. The 

 males from Western Mexico have hairy and somewhat iucrassate tibiae, while 

 those from Eastern and South Mexico, Guatemala and Honduras have spiny tibiae, 

 both forms differing also somewhat in pattern. In a classification which is based 

 strictly on the quantity of difference, the forms of F. vertumnus and P. jwh/zdus 

 with hairy male tibiae would have to be treated as specifically distinct from the 

 forms with spinose male tibiae. But in a system based on true relationship (as far 

 as we are able to make out relationship from the morphological and biological 

 characters known) all the circumstances have to be taken into account. As the 

 spiny-legged P. hjcimenes and P, erithalion are very closely related to hairy-legged 

 P. ipliidamas, it is quite natural that the difference which is constant and specific 

 in these insects should appear in other species as a difference between geographical 

 forms, the development of a species into geograi)hical forms being the first step 

 towards the splitting up of one species into more species which can exist side by 

 side, no longer being separated geographically, as are the geographical forms. 



(J ? . Sexes similar, female a little paler than male ; forewing rarely with 

 white dot R- — II' (some Honduras males), on underside occasionally grey scaling 

 in front of cell. Hindwing with red band from SO'- to abdominal margin, standing 

 much nearer distal margin than in the allied species. 



Early stages not known.
