This species has a wide range in Tropical America, and does not 

 become perceptibly modified. I found it everywhere common on 

 the Amazons. It has a rapid and strong flight, and performs exten- 

 sive migrations. The males assemble in great numbers with those 

 of the Callidryades on the moist margins of rivers. 



9. P. Lycimnia, Cram. 

 P. Lycimnia, Cram. 105 e.f. 



Inhabits only the shades of the forest, and is of slow, feeble flight. 

 Further south, at Bahia and Bio Janeiro, it becomes strongly modified, 

 the modification ranking as a distinct species, viz. P. Limnoria, Godt. 



Section 2. Fore-wing upper radial connected with the cell by 

 means of an upper discocellular. 



10. P. Hirlanda, Stoll. 

 P. Hirlanda, Stoll, 35. f. 1. 



Ega and St. Paulo, Upper Amazons : very rare. Stoll gives Bengal 

 erroneously as its habitat. It frequents the moist margins of waters. 

 P. Helvia, Latr., taken by Humboldt and Bonpland in Columbia, is 

 doubtless a local variety of this species.

5 . Differs from the 3 in wanting entirely the orange apical spot, and 

 in the ground-colour of the wings being pallid ochreous-white.
