AMPELOPHAGA CHCERILUS 113 



transparent look. The sides of the brown horn were 

 lighter and reddish. The segments were very plainly 

 marked, and the third and fourth were swollen. There 

 were faint face-lines. 



The third molt followed in five days. The cater- 

 pillars had very small heads, with whitish face-lines. 

 The body was very yellow-green, with a faint dorsal 

 line. The last pair of obliques were very white. The 

 caudal horn was blue, with black granules. The feet 

 were quite red, the spiracles bright red with a yellow 

 dot at each end. Other larvae had the horn blue at 

 the base and light pink above. 



The fourth molt occurred five days later. The head 

 was marked by face-lines which continued over the 

 first and second segments, much fainter on the second. 

 The body was bluer green than in the last molt and 

 darker below the lateral line. The obliques were much 

 whiter. Some horns were very blue, others pinkish. 

 Some larvas were brown instead of green. The anal 

 shield was edged with lighter green or brown, according 

 to the body-color of the crawler. The swollen seg- 

 ments were very conspicuous and had no dots. The 

 illustration shows one green and one brown caterpil- 

 lar. They posed side by side as if for comparison. 



Before pupating they turned pinkish on the dorsum, 

 and, thirteen days after the fourth molt, began spin- 

 ning loaves together with a " fish-net " cocoon. Three 

 days later the pupie cast the larva-skin, liaving lived 

 thirty-six days from the egg. They ate Azalea viscosa 

 aiidVihiiniMmdentafiiui, and ate from the margin of the 

 leaf after the second molt. 



We have not found choerilus common, but have oc-
