ping at joint 12 ; on each side of this dull yellow-green, 

 with a macular brown subdorsal line. Sides sloping, a 

 little incurved, red-brown, with a broken yellowish line ; 

 a similar but continuous line along the basal ridge. Body 

 much covered with short, stiff, brown hairs. Head cor- 

 date, smooth, yellow-green. 



It moults again in three or four days, when it is .12 of 

 an inch long, shaped much as before, with a tuberculous 

 ridge across each segment from 4 to 11. Color red-brown 

 and dull yellow-green. Dorsal band red, tapering pos- 

 teriorly to a point, with a central green line ; outside 

 this band a green one, with a red-brown speck on each 

 segment. Sides red-brown, with green central line ; basal 

 ridge green. 



In five days it moults the third time, and measures .3 

 of an inch ; but seven days later, when ready to pupate, 

 it is .56 of an inch long. The summit of the dorsum is 

 flattened, a little concave, covered by a broad band cut 

 by a paler line; the remainder of the elevated ridges 

 yellow-green. Sides red-brown, with an indistinct green 

 line. Basal ridge green, head yellow-green. One day 

 after moult the color changes to port-wine red ; the sub- 

 dorsal area remains yellow-green, but is red-tinted on 

 the posterior part of each segment ; the sides the same 

 red; a pale red line along the basal ridge; about the 

 spiracles a little green. 



Chrysalis .3 of an inch long ; black or blackish brown, 

 with obscure red band, and on each side a narrow black 

 stripe in the middle of the abdomen. In this stage the 

 species hibernates.
