290 ^^^ BUTTERFLIES OF THE 



In from four to eight days a larva .04 of an inch long 

 hatches from the egg. This has the under side flat, legs 

 retractile, upper side rounded, highest at joint 4, from 

 which the dorsum and sides slope gradually to joint 13. 

 Surface pubescent. On each side of the dorsal line is a 

 row of white clubbed hairs, with similar hairs at the 

 base and in front of joint 2, making a fringe round the 

 body. Color greenish white or brownish yellow. Head 

 minute, obovoid, retractile, black. 



After the first moult, which occurs in from three 

 to five days, the length is from .07 to .08 of an inch ; 

 the color of the spring and fall broods is brownish yel- 

 low, that of the summer brood the same, and also green- 

 ish white and reddish. 



The second moult occurs in from three to five days 

 more, the length being from .12 to .16 of an inch. The 

 shape is as before, but the dorsum is covered from joint 

 3 to joint 10 by a low, broad, continuous, tuberculous 

 ridge, cleft to the body at the juncture of the segments, 

 the anterior edge of each joint depressed, the sides in- 

 curved. Joint 2 is more flattened than before, and the 

 outer border is thickened into a rounded rim, leaving 

 within the curve a flattened, depressed space. Color in 

 spring pale green, the dorsum whitish, usually a reddish 

 dorsal line from joint 3 to joint 10. In summer vari- 

 able, buff or pale green without spots, joint 2 brown ; 

 in some the dorsum and sides are mottled with dark 

 green and brown ; occasionally one is wine-red, or red 

 with a white basal stripe, and white along the tuber- 

 culation. In fall dull green, more or less marked with 

 brown. 



The third moult takes place in three or four days
