portion to the size of the body, rising from shining black tubercles, taper- 

 ing to an irregular top, and surrounded by many short black bristles set 

 at a small angle ; head cordate, black, glossy, with many tapering hairs 

 or processes on the face. Other examples are yellow-fulvous ; others 

 have a continuous red-fulvcus band on dorsum, rather wider than the 

 tubercles of the dorsal row of spines ; or this band is macular, a rectan- 

 gular spot being on each segment, bearing the spine ; the lower part of 

 side is also red-fulvous, and the intervening space is dark-brown, forming 

 a sub-dorsal band the length of the body. The red on dorsum is some- 

 times reduced tu a small patch on each segment, on rear. Others are 

 black throughout, except that over the upper part are specks and minute 

 spotes of white or yellowish ; others are black, but from the second lateral 

 row of spines to basal ridge is a band of greenish-white and black, mot- 

 tled, and sometimes the upper edge of this band shows a macular fulvous 

 line. In all, the spines are black. There are at least three distinct types 

 of larva : 



i st. — All red- or yellow-fulvous. 



2nd. — The dorsum and lower part of side fulvous ; the subdorsal 

 area dark-brown. 



3rd. — All black, or black with a greenish band on side. 



From fourth moult to pupation, about seven days. 



Chrysalis — Length, .45 to .52 inch <$ ; .55 to .64 inch $. In an 

 example of which the length was .52, the breadth both at mesonotum and 

 abdomen was .2 inch ; cylindrical, shape of Melitfea ; head case short, 

 narrow at top, and a very little incurved, the sides excavated ; meso- 

 notum rounded both ways and rising to a slight prominence on the rear, 

 but not carinated, followed by a slight depression ; abdomen conical ; 

 the wing cases somewhat elevated, bevelled down to the abdomen on the 

 margin ; colour the first day white, pink-tinted, then becoming ivory- 

 white, specked and spotted with black, with some black bands or stripes; 

 a stripe across the top of head case, a band from end to end on the 

 ventral side ; some spots on the head case ; on mesonotum two spots in 

 front, two on rear, one on either" side (at the tubercle) ; in some ex- 

 amples these are mere points, but in others large, and form a ring around 

 the middle of the mesonotum 3 on the abdomen a black crescent on the 

 anterior side of each tubercle ; on middle of wing case a bent bar, two 

 patches at hind margin, and several dots ; the tubercles correspond to 

 the spines of the larva, and are low, conical, orange. But there is great
