182 THE CANADIAN ENTOMOLOGIST. 



raised a little above the other ; on 13 but one ; on 2 are three lateral 

 tubercles, each of which gives two hairs, and placed, one above, one in 

 front of, and one below, the spiracle ; on 3 and 4, in line with the lower 

 tubercle of 2 and the lower of the pair on the segments after 4, is a single 

 tubercle and hair ; over the prolegs are two short hairs each, and in same 

 line, on 5, 6, 11, 12, is one hair; head rounded, a little depressed at 

 suture, color black, shining ; surface much covered with fine tubercles and 

 bent black hairs. (The tubercles and hairs of this species are similar, and 

 similarly placed, to those of V. Ajitiopa). Duration of this stage about 

 two days. 



After First Moult. — Length at 12 hours, iVt inch ; the middle of dorsum 

 green cut by a brown line ; the junctions of segments also green ; the rest 

 of upper half black-brown, below this and the under side yellow-green (some 

 examples are darker than others, more brown, less green) ; above the 

 spiracles is a yellowish wavy line from 5 to 10 inclusive, and with the 

 spiracles a brown line ; there are several rows of spines, one dorsal and 

 three on either side ; these are disposed as described in last stage, are low, 

 rounded, with a small cone on summit ; from the apex a single long black 

 hair, and five or six short hairs around the basal part ; on the cross-ridges 

 of each segment after 2 are many fine points, each with a short hair; 2 

 has a blackish dorsal patch, with many hairs, bent forward ; feet brown ; 

 pro-legs green ; head cordate, shining, black, thickly covered with fine 

 low conical tubercles, varying in size, each with its hair. Duration of this 

 stage about two days. 



After Second Moult. — Length at 6 hours, iVo inch ; color black over 

 dorsum to middle of side ; a mid-dorsal black line, with a pale gray-green 

 line or stripe on either side of it ; on the cross-ridges many white points, 

 each with long whitish hair ; in some examples the lower part of the black 

 area is mottled with green-yellow ; in one was a greenish patch on mid- 

 dorsurn on front of each segment after 2 ; the lower half of side green- 

 yellow ; on this area, with the spiracles runs a blackish line overlaid by a 

 yellow line ; under side yellow-green ; the spines now long, slender, 

 tapering to a point, with a bristle at top and eight or ten about the sides ; 

 color of the five upper rows black, of the lower laterals yellow ; head as 

 at second stage, the tubercles more numerous, and more prominent, the 

 one on each vertex a little largest, some white, some black, the hairs all 

 black Duration of this stage less than two days.
