NEONYMPHA II. 



Young Larva. — Length .12 inch; cyUndrical, the thoracic segments equal, 

 then tapering on dorsum and sides to 13, wliich ends in two sliort conical tails, 

 from the end of each of which proceeds a long bristle, the space between the 

 tails angular ; color delicate green ; the upper surface presents six rows of low, 

 conical black tubercles (Fig. &*), each giving out a short black bristle or process, 

 thickened at the end ; on 2, 3, 4, these are nearly in cross line, on 4 to 12 in 

 triangle, the dorsal one on front of the segment, the sub-dorsal at the rear, the 

 lateral a little before the middle; on 13 there are eight, in two rows of four on 

 front and rear, besides the pair at ends of tails ; on 2 the cross line is to the front, 

 and behind and between the upper pair is an additional one ; also in front of 

 spiracle is a small tubercle, and just below it a fine hair; along base of body is a 

 row of fine short hairs, two on each segment from 2 to 13 ; feet and pro-legs 

 green ; head about twice as broad as 2, sub-globose, flattened frontally, a slight 

 angular depression at top ; on each vertex a low semi-ovoid process, at the top 

 giving two divergent black hairs; just below vertex is a similar smaller process, 

 and two others in vertical line at side face, each of these with a single hair; 

 color black. (Figs, h to ¥'.) Towards the end of the stage the color changes to 

 decided green and several longitudinal stripes appear ; on either side of the green 

 mid-dorsal one is a whitish stripe, and others on middle of side, and along base. 

 (Figs, h, b^.) Duration of this stage about eight days, but depending on the 

 weather. « 



After first moult: length .22 inch; slender, the dorsum slightly arched, the 

 tails longer, tapering ; color of body green, the tails tinted red ; surface thickly 

 covered with fine yellow tubercular points, partly arranged in longitudinal rows, 

 ten in all, one on either side being next the mid-dorsal green stripe, one sub- 

 dorsal, two on side, one along base, each point giving a fine short whitish hair ; 

 under side, feet and legs green ; head rather ovoidal, truncated, and depressed at 

 top ; on each vertex a low compound process, made of a central cone, and othei's 

 about its base, each with its bristle ; surface of face rough with sharp tubercles 

 of varying size, each with short bristle ; color of back of head and the front 

 triangle deep green ; the rest of the front and the processes on vertices red- 

 brown, with two green patches one on either side the suture ; ocelli emerald- 

 green. (Figs, c, r.) But some larvae have the head wholly green, the vertex 

 processes reddish ; one had a brown band across forehead, the rest green; another 

 had the front face except the triangle brown, the cheeks green. To next moult 

 about nine days. 



After second moult : length .3 inch ; shape as before ; color yellow-green ; 

 stripes as before ; head as at last previous stage, sometimes wholly green, some-
