92 CATERPILLARS AND THEIR MOTHS 



plate and props had a glassy look. The fourth seg- 

 ment was slightly swollen. 



Three days later they were yellow-green dotted with 

 yellow, with a yellow subdorsal line, and a yellow, 

 wavy stigmatal line on the first three segments, 

 also seven yellow oblique lines edged above with 

 dark green. The head showed very faint 'yellow face- 

 lines, and the legs and props were yellower than the 

 body. 



In this stage they had a funny way of resting with 

 all the props holding a midrib or stem, while the fore 

 part of the body was thrown up and backward until 

 the head was over the ninth segment, mouth-parts 

 and legs being up in the air. They still liked rather 

 young leaves, though not the very youngest ones as in 

 the last stage. 



Four days later they molted, and this time there 

 was a decided change in their appearance. They were 

 seven eighths of an inch long, and the head was apple- 

 green, with yellow face-lines, and was rough. 



The body was of a bluer green than the head, and 

 the third and fourth segments were slightly swollen ; 

 there was a yellow stigmatal line on the first three 

 segments — the thoracic segments — and also a yellow 

 subdorsal line edged above with dark green. The 

 dorsal line was dark green, and the body had trans- 

 verse rows of yellow dots, except the first segment. 

 This time there were eight yellow obliques edged 

 above with dark green. Seven is the normal number 

 of oblique lines for sphingid larvae. The legs were 

 yellow, the props green. The caudal horn was long, 

 slender, green at base, black above, white at tip, and
