Second stage. — Same as in the first, with these exceptions : Head about 

 three-fifths as wide as the first segment; this segment bears two addi-

 second and third segments each with an additional but much smaller 

 wart in front of those in the stigmata] region, each bearing a single 

 short bristle; bristles, except those in the stigmatal region, black, the 

 warts in this regioit reddish, and larger than the others. 



Third stage. — Same as in the second, except that the head is propor- 

 tionately narrower, being only about one-half as wide as the first seg- 

 ment. 



Fourth stage. — Same as in the third, except that the warts in the sub- 

 dorsal and supra-stigmatal region on either side of the third, and usu- 

 ally of the second segment, are connected by a black spot, and the body

 c, pupa, naked, ventral view— all enlarged. (Original.) 



Pupa. — Partially inclosed in the old larval skin, which is of a whitish 

 color, marked with black dots, which indicate the position of the warts 

 on the larva as described above ; this skin is rent from near the front 

 edge of the first segment to the middle of the eighth ; the exposed part 

 is mottled light and brownish red, the first segment marked with two 

 dorsal black dots, or the entire dorsum of this segment, and also that of 

 the second and third segments, black ; abdomen with a polished-black
