Para and Guiana ; within this range the species is constant in its 

 specific characters in both sexes. On the Upper Amazons the follow- 

 ing allied form occurs ; I consider it to be a local modification of 

 JEneas, although strongly marked. Neither form was found in 

 intermediate districts, nor has any connecting link yet been seen.

 Lower Amazons and Para. Like the five preceding species, this is 

 an exclusive forest-dweller, but it is the weakest flier of its group ; 

 the 2 especially flying feebly and low, in the manner of certain 

 Heliconidae. The tf, however, flies higher and stronger. The 

 following I consider a local modification of it, in the same way as 

 P. Bolivar is of P. JEneas.

 I met with only one example of this very distinct species, at 

 Ega.
