THE GOSSAMER-WINGED BUTTERFLIES 



United States east of the Rockies and north of 

 the Gulf States. The tails of the hind wings are 

 not very long, and sometimes the outer one is 

 just indicated by a point. The many white hair- 

 streaks that cross the lower side of the wings give 

 the butterfly its name. It is always found near 

 thickets, and it has a lively, nervous flight. The 

 caterpillar may attack the pulp of the fruit as 

 well as the leaves of its food-plant. The first 

 butterflies appear in July and disappear after a 

 short time. It is single-brooded, and winters as 

 an egg.

Plate XXXIV, Fig. 7, 8, 9 



The upper surface of the wings is dark brown, with the disk 

 more or less deeply suffused with brassy yellow in the male or 

 tawny in the female; the tails of the hind wings black tipped 

 with white. The lower surface is deep green, with the portion 

 of the fore wings covered by the hind pair pale slate brown ; 

 the fore wings are traversed by a nearly straight submarginal 

 white stripe bordered interiorly with brown; there is a similar 

 but tortuous stripe on the outer half of the hind wings; near 

 the base of the hind wings there are two white spots bordered 

 without with brown, and near the outer margin of these wings 

 there is a series of black spots, margined without and more or 

 less covered with white. Expanse of wings one inch.
