376 THE BUTTERFLIES OF THE 



After the second moult, which occurs eleven days 

 later, it is .55 of an inch long, the ground color yellow- 

 ish black, with about six transverse yellow lines to each 

 joint ; the interspaces being dotted with yellow, giving 

 the body a yellowish appearance. The last two seg- 

 ments are a little orange-tinted. Head cordate, this and 

 the second segment brownish black, the latter shining, 

 the head with an orange spot on each side above the 

 ocelli. 



In seven days more the larva moults again, when it 

 is .75 of an inch long, with the color of the body un- 

 changed ; but the head is dark brown, and the second 

 segment is black, with the sides and under parts red; 

 the rest orange, the prolegs with a dark yellow base. 



The larva moults the fourth time in four days more, 

 when it is .9 of an inch long, but at the close of this 

 stage, before pupating, it is 1.15 inches long. The head 

 is broader than the middle of the body, a little oblique ; 

 and the second segment tapers anteriorly to a distinct 

 neck. The body is a little flattened, tapering from the 

 middle each way. The color remains about the same, 

 the head assuming a little more of a wine color, and 

 the top of the second segment and the jaws dark brown, 

 the sides and feet on this joint about as before. 



The time from the last moult to the change to a chrys- 

 alis varies with the season. One that 

 moulted September 1 pupated October 4. 

 This change takes place in the cluster 

 of leaves it has woven together for a 

 E. Tityrus, chrysalis. re treat during the larval period. Before 

 pupating it lines the retreat with a thin coating of silk. 

 The chrysalis is .76 of an inch long, the head-case
