A species of very wide range embracing not only the Southern States of North 

 America but also the greater portion of the southern continent as well as the West 

 Indian Islands, being everywhere a common familiar species. In Guatemala its range 

 in altitude extends from the sea-level to a height of 5000 feet in the mountains. The 

 males vary to some extent as to the width of the apical dark border of the primaries, 

 which is widest in South Brazilian examples and narrowest in those from Central 

 America and Mexico. Females vary more than the males, being in some instances of 

 a pale ochreous hue, in others the wings are of a sooty colour ; this is especially the 

 case in two examples from Callao given us by Mr J. J. Walker.

Boisduval's description of this species was based upon a female from Mexico; 

 Doubleday described the male as P. habra from specimens from the same country. 

 Different as these two insects are in coloration there can, we think, be no doubt 

 of their being sexes of the same species. The range of P. viardi includes Southern 

 Mexico and Central America as far south as Costa Rica, and though the male is
