CCENONYMPHA I. 



4, two each from 5 to 12, one on 13 ; also over the pro-legs, 7 to 10, are two hairs 

 each, but on 13 there are three, besides two clubs ; the processes of the upper 

 rows are recurved, except on 2, where they turn forward, those of the basal row 

 bend down and back ; feet and pro-legs yellow-green ; head broader than 2, 

 rounded, narrowing toward the top, a little depressed ; color carnation ; over the 

 face a few short clubbed processes, thick like the dorsals. (Figs, b to &".) Dura- 

 tion of this stage twelve to eighteen days. 



After first moult: length .19 inch; stouter; the dorsum less sloping, curving 

 rapidly from 11 to end ; color yellow-green ; the mid-dorsal stripe dark green, the 

 three side lines paler, and not very distinct, the upper one edged on its lower 

 side by whitish-green: the basal ridge yellowish; tails red at end ; surface covered 

 thickly with low rounded tubercles, each with its short, bent, slightly clubbed 

 white process ; feet and legs green ; head sub-globose, broader than 2 ; color 

 dark green ; the face much covered with fine white tubercles with short pro- 

 cesses. (Figs, c-c^.) Duration of this stage about seven days. 



After second moult: length .32 inch; scarcely differing from last previous 

 stage ; the tubercles finer, much more numerous, rounded, the processes short, 

 straight, and of uniform thickness. (Figs, d-d^.) To next moult ten days. 



After third (and last) moult: length .50 inch; shape as before; color ^-ellow- 

 gi'een. But soon after the moult some of the lapvaj began to change color, and 

 within four days had become red and buff. 



Mature Larva. — Length .84 inch ; slender, scarcely arched dorsally, of even 

 height and width from 3 to 7 or 8, then tapering gradually to 13; ending in 

 two short conical tails, which meet at base and are rough with tuberculations; 

 color yellow-green, striped longitudinally with yellow, there being two narrow 

 stripes near together on mid-side, and a heavier and deeper colored basal stripe; 

 on mid-dorsum a dark green stripe, edged by pale green ; the tails red at tip ; 

 under side, feet and legs bluish-green ; whole upper surface thickly covered with 

 fine sub-conical white tubercles, each of which gives a fine short white process ; 

 these are either tapering, or slightly clubbed, or cylindrical, the effect being to 

 give a downy coat ; head broader than 2, sub-globose, narrowing toward top, de- 

 pressed at suture; much covered with fine tubercles and short processes. (Figs, 

 e-e^.) 



Or the body was reddish with a buff tint, the stripes yellow ; the under side
