LIMENITIS I. 



parts suftused with red ; the top, sides, and cleft, red ; the tubercles mostly col- 

 ored like the ground they stand on. As the larva approached fourth moult the 

 red parts became dull and at length mostly brown. (Fig. e.) To next moult 

 G days. 



After fouith moult: length .0 inch: general color very much as immediately 

 after third moult; shape, same ; segment 2 yellow-bufl", mottled with black, 3 dark 

 buff, iuuuaculate, the ridge as before, and the processes, which are .OG inch long; 

 4 is mottled buff, red and black, and on either side of the main ridge is a lower 

 and narrower one ; on the main ridge are no processes as before, but on all these 

 ridges are round, glas.sj', bead-like tubercles, thickly set, and red colored ; on 

 middle of dorsum of this segment, in front of the anterior row of these beads, are 

 two similar beads, but large and ovoid, and directly iu front of the space between 

 these two are small round ones; on 6 the mamniilloid processes are as before, and 

 castaneous ; between them are four red beads, arranged in two j^airs at anterior 

 and posterior parts of the segment ; there is also on this segment a posterior 

 narroAV ridge thickl}" set with beads ; G is bufi* largely red on dorsum, with a 

 beaded ridge and scattei'ed beads in front ; the patch on 8 is Wue-gray, and ex- 

 tends partly over 7 and 9; 10 and 11 are alike, red with beads; on 10 are two 

 small dorsal crested red tidaercles, and on 11 two larger, these crests all yellowish; 

 12 and 13 are red, mottled with lilack ; the processes on 13 as at last stage ; on the 

 sides, on several segments, are beads and small tubercles ; the ridge at base of 

 body is gray-bufi", distinct on last segments ; feet and pro-legs red-brown ; head 

 nearly same shape as at last stage, rather broader iu proportion, the tubercles 

 similar, except at the vertices, where they are longer and larger, the largest 

 of all oblicjuely truncated; color of both head and tubercles amber, the ocelli 

 black. (Fig./.) 



Mature Larva. — Two dnys after fourth moult the red portion began to change 

 to green, olive, and partly a light and deep green ; individuals varied in this re- 

 spect ; the dorsal patch changed to sordid-buff, in one case to dull red-buff, in 

 another to whiti.sh, the anterior segments to gray or whitish, in one case to dark 

 buff, the side stripe to pink, and on last segment to pure white ; the beads from 

 red to blue; the head became a dark drab. The larva at maturity was 1.2 

 inches long. (Fig. y^) Nine days after tiftli moult it began to spin a button of 

 white silk on the under side of a willow Ijranch, and thirty-six hours later l^e- 

 came chrysalis. 



C11RT.SALIS. — Length .'J inch : sub-cylindrical, the abdomen somewhat com 

 pressed laterally, and termhiating rather abruptly ; the edges of the wing-cases 

 throughout very prominent and turned up, the middle area incurved ; head-case 

 long, narrow, and tapering, truncated, the vertices ending in two wavy ridges, the
