224 LEPIBOPTERA OF NORTH AMERICA. 



Expands from five and a half to six inches. 



Larva, light green ; the second segment, surmounted with two 

 red tubercles, having a number of short black hairs; the third seg- 

 ment has two larger tubercles ; the others are crowned with oval 

 yellow warts with hairs at the end ; the last segment has but one 

 of a larger size. On the side, two series of long, light blue tuber- 

 cles, and a shorter series over the first five segments. 



Feeds on apple, cherry, wild plum, currant, barberry. 



It spins an oval cocoon, which is often as large as a hen's ^^^, 

 which it attaches to the side of a stem. Externally it is brown 

 and wrinkled ; inside of this outer covering there is paler brown 

 silk; this covers an inner cocoon closely spun, within which the 

 chrysalis reposes.

Eyes and antennse dark brown ; the latter broadly pectinated in 

 the males. Thorax and abdomen dark brown. Legs and under 

 side of the body reddish-brown. Wings same color, falcate on the 

 outer edge*. A Sinuous, grayish line crosses both in the middle ; 

 outer margin drab, through which passes a sinuous, dark reddish 

 line; an ocellate black spot, surmounted by a blue crescent near 

 the tip, between which and the tip there is a zigzag whitish line. 

 The wings near the upper angle are of a rich flesh color. 



The secondaries are similar, except the drab margin, on which, 

 besides the sinuous line, there is a series of oblong dark brown spots 

 between the line and ground color of the wings. 



The under side is similarly marked, but the color approaches to 

 a crimson tint. In the middle of the superiors there is a small 

 sagittate spot of dark red ; the inferiors have an indistinct, short, 

 white line in the middle. Expands three inches and a half. 



The female differs considerably from the male. The body is 

 reddish-brown. The upper surface of the wings is bright ferrugi- 

 nous. They have the ocellated spot and the zigzag line near the 

 tip as well as the sinuous line on the drab margin as in the male, 

 but the oblong corresponding spots on the inferiors are ferruginous 

 instead of brown. 



Both lower wings are crossed by an undulating yellowish-white 

 line, the inner edge of which is black and the outer gray. At the
