 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 roLuided ; color light brown, changing, as the stage proceeds, to greenish- 

 white, mottled with bi'own ; armed with six rows of spines, one sub-dorsal, one 

 middle, and one infra-stigmatal (arranged as desci'ibed under mature larva); 

 the.se spines are short, slender, and tapering, Ijlack, with a few short black bristles 

 on the sides; on second .segment a chitinous dorsal jjatch 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, r, head spine f\) To next moult two days. 



After second moult: lengtii .5 incli ; color dull white, uiottliMl or spotted with 

 yellow-brown; under .side brown; the spines long, shar[) ; head as before the 

 spines longer, directed forward, a little recurved. (Fig. d.) To next moult two 

 days. 



iVfter third moult : length .7 incli ; slender, whiter than before, but green- 

 tinted ; dorsal spines .1 inch long, upper laterals .()',) inch, lower .07 inch; head 

 greenish-yellow, the processes like the body sjiint-s, .08 inch long. (Fig. e.) 

 To next moult three days. 



After fourth moult: lengtii 1 inch, and in three days reached maturity. 



jvI.\TUi!r. Larva. — Length 1.25 to 1.5 incii ; 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-dor.sal 

 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 

 green tint ; segment 2 has a dorsal chitinous bar divided in middle, and on either 

 part are two black tul)ercles 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 Idack, small at base, 

 tapering to a sharp point, and about each are from -3 to 7 short black bristles
