her, hilt nsiuillv thev are many, and as each ogives a lony- curved white 

 hair, the surface is woolly; the spines are in seven principal rows, one 

 dorsal, three on either side; in addition tin-re is a row ol smaller s])ines 

 alon^' base, h'om 3 to i i, over the leet and leys two to each segment in 

 liorizontal rt)w; on 4 two in \'ertical row; on 5 two in horizontal and 

 a third below, the three making' a triangle; on 11 and 12 one each; on 

 under side of body, on 5, 6, 11 and 12 are numerous small s|)ines on 

 the cross ridges; the dorsal spines run from 5 to 12, and together with 

 their bases, are orange; the first laterals run from 3 to 13 and are black; 

 the second laterals run from 3 to 13, are black, with orange around 

 base, but usually wanting on the dorsal side; the third or lower laterals 

 run from 3 to 11, the one on 3 small and orange, that on 4 orange, 

 both orange at base, the rest orange with a little ])atch of same color 

 at base on upper side only; the row along base wholly orange; the 

 spines are moderately long, slender, tapering, rough with tubercula- 

 tions, from each of which springs a long hair, those of upper rows 

 partly white next base of spine, the others black ; 2 has a collar of low 

 black spines with many long black hairs; feet black, pro-legs brown; 

 head ob-ovoid, truncated, depressed at top, the vertices low, sub-conic, 

 and rough (as well as upper part of face) with tubercles, each of which 

 gives a long stiff black hair, so that the top of the head bristles with 

 these; color black. F"rom last moult to pupation about fourteen days. 

 Chrysalis. — Length .8 inch; breadth across mesonotum .26 inch, 

 across abdomen .22 inch; head case narrow, truncated, the top a 

 rounded transverse ridge, the sides incurved; mesonotum rounded, 

 slightly prominent at top and angular, followed by a rounded excav^a- 

 tion; the abdomen stout; the larval spines of dorsal and two upper 

 rows on either side are indicated by low conical tubercles; the spines 

 of third row by a slight elevation on surface; color gray and pearl, 

 marked and spotted with black, or brownish black, these marks and 

 spots often edged with orange; the tubercles each edged on front side 

 by a black crescent; behind the dorsals two short, oblique black bars, 

 on some segments confiuent with the crescents of the first lateral row; 

 on segments 7 to 1 1 is a row of short black bars on the posterior part 

 of each; on the ventral side, a blackish band of irregular outline from 

 last segment to head, there bifurcating; the antennae cases alternate 

 black and gray; a long black patch lies on middle and basal part of 

 wing cases, usually edged with orange, and crossed by orange neura- 

 tions; along the hind margin of wing a series of stripes or small black 

 spots, rounded or serrated, and there is a second interior row varying 

 in like manner; on the sides of mesonotum two curved bars meeting 

 at an angle on the carina; a straight bar higher up running with the 

 dorsal line; a i'ew patches on top of head case. Duration of this stage 

 about twelve davs.
