 Body black, with a yellow lateral stripe. 



On the under side the fore wings are about as above ; 

 the hind wings have the band white, with orange clouds 

 on its outer edge between the veins, and each lunule has 

 a broad dash of orange ; the blue clouds more prominent 

 than above. There is also a dull yellow stripe across 

 the wings nearly parallel with the inner margin. 



The egg is spherical, a little flattened at the base. The 

 color is greenish yellow. It hatches in five days. 



The young larva is .1 of an inch long; cylindrical, 

 greatly thickened from joints 3 to 6, from 6 tapering

 passes along the sides of segments 3 to 8 ; segments 12 

 and 13 white. It moults in four days. 



After the first moult, its length is .33 of an inch. In 

 this stage the two subdorsal rows of tubercles, or fleshy 

 processes, are minute on joints 6 to 10 ; the whole of 

 the two dorsal rows minute. Color yellow-brown, 

 darkest posteriorly ; white marks as before. 



In two days it moults again, when it is .36 of an 

 inch long ; the same general shape as before. Joint 3 is 

 a little excavated on the anterior part of the dorsum ; 

 on the second is a square-topped ridge, but the processes 

 have disappeared. On joints 12 and 13 the processes 

 are as during preceding stage, but the rest of the dorsal 

 and subdorsal have disappeared. Color yellow-brown to

 hue; white stripes as before. During preceding stage
