132 CATERPILLARS AND THEIR MOTHS 



The caterpillars ate voraciously for a week, then 

 molted for the fourth time. Carolina now showed 

 three distinct forms — one just like the last molt, ex- 

 cept that the horn was red, shorter in proportion, and 

 curved backward. The second had a plain green head *, 

 the body green, minutely dotted with white, and with 

 the obliques white, edged above with broken black 

 lines. The legs were black and white, looking spec- 

 kled ; the props were green ; the anal plate was edged 

 with yellow-green. The horn was short, stout, rose- 

 red. The third form was of a dirty green, the head 

 plain, the body transversely striated, or finely lined, 

 with black, and with white dots so small as to be seen 

 with a lens only. The obliques were dirty white, with 

 black above. The legs were black and dirty white, 

 the props dirty green ; the anal plate was edged with 

 dull yellow. The horn was short, stout, and dull red. 



There was a fourth form much like the last, but the 

 green was more olive on the head, and there were two 

 broad face-lines of smoky black. The body had a 

 black' dorsal line, somewhat broken, and was of a 

 cleaner green, with a black patch on the dorsum of 

 the first segment. The legs were black and green, the 

 props green with black marks; the horn was short, 

 stout, and red. The spiracles of all were black, with a 

 yellowish dot at each end, in a gray oval. 



No Carolina had the shining look which the green 

 forms of celeus have when nearly full fed, but all were 

 dull of surface, and the dorsum was set with many 

 short pale brown setae, the sides having fewer. 



They fed for ten days, then stopped eating and 

 crawled restlessly until they grew moist, shortened,
