FAMILY GOSSAMER-WINGED BUTTERFLIES. 117 



mostly in Canada and extending southward over the whole 

 of New England and along the Appalachian chain, but 

 not known elsewhere in the East. The butterfly is single- 

 brooded and appears from the wintering chrysalis toward 

 the end of April or very early in May, preceding by a few 

 days the last species (where both occur), and flying till the 

 middle of June. Eggs are laid in May or June, but what 

 the caterpillar feeds on is unknown; it probably matures 

 by the middle of July, and the rest of the year is spent in 

 chrysalis.

This is the only one of our Hair-Streaks which flies 

 almost continuously from May to September; it is found 

 throughout our district, although it has very rarely been 

 taken in any part of Canada; it is to be looked for about 

 shrubbery and vines. The insect is double-brooded and
