This is one of the largest butterflies (Fig. 71) found in this 

 State. The wings expand from four inches and six Hues to five 

 inches, and are of a pale yellow color, with a broad, black outer 

 margin marked with yellow spots ; the fore-wings are marked 

 with four black bands, the one nearest the body extending 

 across the hind-wings ; the latter are tailed, and have an 

 orange-colored spot near the hind angle. 



Remedy. — Use No. 14.

[Feeding upon the leaves of the apple tree, a small, dark, 

 yellowish-green, sixteen-legged worm, nearly six lines long ; 

 spinning against the bark an elongate, dirty-white, ribbed 

 cocoon]. ^ 



This larva assumes the pupa form within its cocoon (Fig. 

 72 a and 6], and before the moth issues, the pupa works itself 

 part way out of the cocoon. Several broods are probably pro- 

 duced in one year ; the last brood passes the Winter in their 

 cocoons.
