on front lower face ; color shining black. (Fig. c, magnified.) Duration of this 

 stage five to six clays. 



After second moult : length .22 inch ; same shape ; the stripes almost the 

 same, the white dull, the brown darker ; a whitish line runs with the dorsal row 

 of spines, which are light in color with l)rown tips ; the first laterals are also 

 light and stand on a whitish stripe ; the second laterals on a broad, dark stripe, 

 and are almost black ; the lower laterals, on a white ridge, are white ; the spines 

 "thickly set with short, straight bristles, standing at a high angle, and dark 

 tipped ; under side dark brown ; head sub-cordate, dark brown and black, with 

 a white spot on each vertex, and one on front lower face. (Fig. d, magnified.) 

 To third moult in summer, three days. Where the larva passed the third moult 

 in the fall the interval was from seven to fourteen days. 



After third fall moult : length ..3 inch ; the dorsum light brown edged with 

 fiiint white at the first lateral row of spines, the brown area showing two macu- 

 lar white streaks ; below same spines a black stripe, after which the side is brown 

 with a white stripe in line with lower laterals ; head sub-cordate, shining black, 

 with a gray, illy-defined spot on each vertex, and another on side of face. (Figs 

 e, e", magnified.) At this stage the larva becomes lethargic. 



After fourth moult in spring : length .44 inch ; color yellow-brown dotted 

 with sordid wdiite ; the spines short, stout, yellowish at l)ase, brown above ; the 

 bristles .short, divergent, brown tipped with black ; along the dorsal I'ow a IjJack 

 stripe, a yellow one in line with first laterals, macular, irregular, and a yellow 

 band with lower laterals ; head small, cordate, shining black or lironze, with a 

 few black hairs ; across each vertex a narrow j^ellow bar, a yellow triangular spot 

 on front lower face connecting at the lower angle with a curved bar which run.s 

 to the back of head. To next moult ten days. 



After fifth and last moult in spring : length .G inch ; to maturity eight 

 days. 



Mature Larva in spring. Length .85 • inch ; color blackish-brown, dotted, 

 especially on dorsum, with yellow ; the spines more tapering than at last stage ; 

 stout at base and there mostly yellowish ; the bristles brown, black-tipped ; on 

 dorsimi a black stripe, often wanting ; with first laterals a yellow stripe, and a 

 band of same color next below third laterals ; in some examples there is a black 

 stripe between the two upper lateral rows ; head cordate, shining bronze with 

 black hairs ; across each vertex a narrow whiti.sh bar, thickened at the front 

 and bluntly barbed on outer side ; in front a triangular spot connecting at the 

 lower angle with a sickle-shaped bar on the side. 



After third moult in summer : length .45 inch ; color olive-brcwn, the dor-
