HELICONIA I. 
small, the hairs to 6 inclusive are bent forward, the rest back, and all are de¬ 
pressed ; color pale reddish-brown, like fresh cut cork; legs and feet same; 
head obovoid, a little paler in color than the body; a few scattered black hairs 
over surface ; ocelli black. (Fig. b.) To first moult two to three days. 
After first moult: length .22 inch; cylindrical, nearly even, the segments a 
little rounded ; color light brown, changing, as the stage proceeds, to greenish- 
white, mottled with brown ; armed with six rows of spines, one sub-dorsal, one 
middle, and one infra-stigmatal (arranged as described under mature larva); 
these spines are short, slender, and tapering, black, with a few short black bristles 
on the sides; on second segment a chitinous dorsal patch with hairs; feet and 
legs brown; head obovoid, truncated, a little depressed at the suture, the ver¬ 
tices low, rounded, and on each a short, tapering, blunt, black process, thinly 
beset with bristles. (Fig. c, c 2 , head spine c 3 .) To next moult two days. 
After second moult: length .5 inch; color dull white, mottled or spotted with 
yellow-brown; under side brown;, the spines long, sharp; head as before the 
spines longer, directed forward, a little recurved. (Fig. d .) To next moult two 
days. 
Aiter third moult: length .7 inch; slender, whiter than before, but green- 
tinted ; dorsal spines .1 inch long, upper laterals .09 inch, lower .07 inch; head 
greenish-yellow, the processes like the body spines, .08 inch long. (Fig. e .) 
To next moult three days. 
After fourth moult: length 1 inch, and in three days reached maturity. 
Mature Larva. — Length 1.25 to 1.5 inch; cylindrical, slender, nearly of 
even size from 2 to 12, the segments a little rounded ; color dead white, with no 
gloss, smooth, with no hairs; spotted with black or black-brown, the spots dis¬ 
posed in cross rows, two of which are back of the spines and one on the extreme 
anterior end of the segment; mostly rounded or oval, but those on medio-dorsal 
line are half-oval except the spots on the posterior edges of the segments, which 
are triangular; these spots form one dorsal row and two on either side ; over the 
basal ridge, on 4 to 11, is a brown patch covering the adjacent edges of the seg¬ 
ments ; another patch covers each spiracle; under side reddish-brown with a 
o-reen tint; segment 2 has a dorsal chitinous bar divided in middle, and on either 
part are two black tubercles with hairs; the body furnished with six rows of 
spines, two sub-dorsal, one on middle of each side, and one infra-stigmatal; the 
dorsals run from 3 to 13 ; the upper laterals from 5 to 13, the lower from 5 to 
12; and between 2 and 3, 3 and 4, in line with upper laterals, is a spine ; the 
spines of the four upper rows are straight and erect, but those of the lower row 
are turned down and a little recurved; all are alike, shining black, small at base, 
tapering to a sharp point, and about each are from 5 to 7 short black bristles
