every hair straight and ending in a knob; on 13 is a similar tubercle, equal in 
size to that on 2, and armed in same way, these two being the largest of the row; 
the other tubercles of these rows are small, equal, each with three hairs ; the 
upper lateral rows run from 2 to 12, are small on 2, 3, 4, each with three hairs, 
the rest minute, with two hairs; below spiracles, from 2 to 13, is another row, 
the three anterior ones small, with three hairs each, the others minute, with two; 
in all six rows, three on either side ; head shining black, obovoid, bilobed.

At two days from egg; length .125 inch; color mottled light and dark brown; 
12 and 13 are obscure whitey-brown ; the lateral line distinct. (Fig. b represents 
this point in the stage.) To first moult about nine days. 
After first moult: at 6 hours from moult, length .24 inch; shape as before ; 
color yellow-brown, mottled with dark brown ; on mid-dorsum on 3 is a black 
patch, and one on 4 in shape of a cross; the patch on middle segments is formed 
of two narrow bands which meet on summit of 9, and run obliquely forward 
and down side to middle only ; 8 is wholly white, but on 7 are two small brown 
dorsal spots; sometimes the posterior end of 6 is mottled with white; 11 and 12 
are dull white and brown; along verge of dorsum a whitish stripe from 2 to 13; 
the lower part of side is dull white mottled with pale brown ; 2 has a narrow 
arcuate front ridge, at either end of which is a stout yellow-brown tubercle, 
conical, with short pointed spurs about it, anct each of these as well as the top 
gives out a short hair ; on 11 is a pair of sub-dorsal low brown cones; 12 and 
13 each have a compressed cross ridge on dorsum, and at either end of this is a 
tubercle much like the one on 2, on 13 the size of that, on 12 smaller; on 3, 4, 
5, are two rows, sub-dorsal, of round, glossy, light brown knobs, and on 3 and 4 
each is one below these ; on 3 are two minute knobs between the sub-dorsals, 
and a little in advance of them ; on 4 are two of somewhat larger size, also in 
advance, and on 5 two minute ones more decidedly beyond the sub-dorsals; after 
5 there are no knobs or tubercles to 9 inclusive; head obovoid, brown, the 
front greenish; the surface of head much covered with fine short hairs. (Figs. 
d to cf 4 .) 
At two days after first moult: length .4 inch; the patch on dorsum has now a 
pink tint; the lower half of side of body is whitish-blue ; on the other segments 
there is scarcely any change; on 3, 4, 5, outside of and at base of each sub¬ 
dorsal knob, is a black dash, and on 7 is another in same line. 
At three days after the moult: the color has become greenish, the light parts 
pink-white; a pair of light blue dots appear on dorsum of 9, 10, 11. Duration 
of this stage 4 to 5 days. 
After second moult: length .4 inch ; color either bright green and pale salmon,
