HALESIDOTA CARY^ 207 



the patch. The other segments had three black dots 

 oil each side of the dorsal line, set in a wide V with 

 the point foremost, and another dot on the stigmatal 

 line. The anal shield was black, like the head; the 

 anal props were slender, and white dotted with black. 

 The feet were black, the abdominal props white. All 

 the black was highly polished. The sparse hairs were 

 black. 



The caterpillars lived in a close crowd, eating in 

 lines on the same leaf. At this stage they ate only the 

 green parenchyma, leaving behind skeleton leaves 

 showing where they had fed. They drank water 

 thirstily. 



In four days they spun a web on a leaf, fixed their 

 anal props firmly in the silk, and on the next day 

 molted for the first time. They were very little longer 

 than before, not measuring a full quarter of an inch. 

 Their heads were very shining black, their bodies 

 white with black dots, and their hairs were sparse, 

 black and white. The first segment had the black 

 dorsal patch, and the second and third had each two 

 large black warts on each side of the dorsal line, and 

 one wart on the stigmatal line. The anal segment had 

 two large warts, also black. The hairs were longest 

 near the head. The white of the body was like por- 

 celain. 



The little caterpillars were very active, and crawled 

 so fast whenever the box was opened that it took both 

 of us to clean the box, put in fresh leaves, and keep 

 the caterpillars from escaping over the edge. Yet 

 when the fresh leaves were in and the box closed, they 

 all collected on one leaf as before, and fed in rows.
