 Common in open places throughout the Amazon region ; the males 

 frequent flowers, and resort also, to imbibe the moisture, on the mar- 

 gins of streams. The females are only seen at flowers on the borders 



of the forest.

A widely distributed Neotropical species. I met with it only at 

 Cameta, on the Tocantins.

 Also a widely distributed species, passing even beyond the tropics. 

 In diff'erent parts of its range it gives rise to local forms more or less 

 strongly modified from the type. The following is one of them, re- 

 markable as being more distinct from the type than is the local form 

 (P. Cresphontes) inhabiting the Southern States of North America.

 in the interior of the province of Bahia.

Local var. (8) Patros, ?, Gray, Cat. B.M. p. 43. pi. 7. f. 6, 7, 8. 



The type is very abundant at Para and on the Lower Amazons. 

 The var. Patros, which affects the 5 only, is peculiar to the Upper 

 Amazons. The J inhabits open places in company with P. Thoas 

 and allies, but sometimes descends into sunny breaks in the forest ; 

 the $ almost exclusively inhabits the foi-est, being found at flowers 

 on its borders only in cloudy weather. 



31. P. Dolkaon, Cram. 

 P. Dolicaoii, Cram. 17 c. D. 



Found throughout the Amozon region, sparingly.
