94 CATERPILLARS AND THEIR MOTHS 



and yellow. One boxful molted but three times, omit- 

 ting the second molt, and fed for twenty days ; another 

 lot molted four times and fed for sixteen days, while 

 one molted four times and fed for twenty-six days. 

 In most cases the obliques almost disappeared before 

 pupation. 



These caterpillars grew very sluggish after the last 

 molt, and when they stopped eating crawled very 

 slowly about the tin, then stayed still and pupated 

 without spinning. 



In the stage before the last molt they were very 

 petulant when disturbed, twitching their bodies and 

 jerking from side to side like the caterpillars of ahhotii 



The swollen segments seem to show their kinship 

 with Amplii'on nes'sus, Ampeloph'aga my'ron and A. 

 chrn'rilus, PMlam'peliis pando'rus and P. a'chemon, all 

 common on woodbine, and most of them on grape. 



The pup^ were a little over an inch in length, 

 brown speckled with darker brown, the dorsum and 

 wing-covers being much darker. They had a sharp 

 cremaster, a pointed projection on top of the head, and 

 one on each eye-cover. Under a lens the dark spec- 

 kles showed as pits. The pupse were slender and not 

 as active as many sphingiu pupae, hardly writhing 

 when held in the hand. 



The fore wings of the naoth are in shades of brown, 

 gray, and silver-gray, with a white discal dot. The 

 hind wings are of deep rust-red, with lines of brown 

 and gray, and gray borders. The body is gray, and 

 the abdomen has brown spots on the dorsum and tip. 

 The whole under surface is much lighter than the 

 upper.
