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

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

 tional bristles near each corner, and two others in front of the middle ; 

 second and third segments each with an additional but much smaller 

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

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

 warts in this region 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 suprastigmatal region on either side of the third, and usu- 

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

 finally becomes covered over with a light gray powder; length when

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 j^art 

 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

 interrupted dorsal line; length, 4 millimeters (Fig. 9).
