160 CATERPILLARS AND THEIR MOTHS 



was green at base, blackish green on the front and 

 lighter behind, slightly rough, pointed, long, and slen- 

 der. The legs were green at base, then yellow, and 

 had blue-black tips. The props were green, and the 

 anal shield was edged with yellow-green. The crawlers 

 ate more now, but were dainty and seldom ate the 

 whole of a leaf, eating part and then leaving it for an- 

 other. They were never voracious like celeus or Uneata, 

 and in all their ways belonged to the aristocracy, if we 

 may think of caterpillars as aristocratic. 



For six days they ate and grew, but showed no 

 signs of pupating, and surprised us by molting for the 

 fifth time. This time they changed much. The head 

 was blue-green, with small dark warts or tubercles, 

 and had a line of blue-purple on the edge so far back 

 as to be hidden by the first segment when at rest. 

 The body was yellow-green, very white-green on the 

 dorsum. The thoracic segments and venter were 

 granulated with white. The obliques were bright 

 pink, shading into yellow on the dorsum, and edged 

 above with deep green. The last pair were white in- 

 stead of yellow, and continued up the sides of the 

 horn as white granules. The horn was blue-green in 

 front and behind, the anal plate lightly edged with 

 yellow. The dorsal line was very blue-green, edged 

 on each side with white. The legs were green, ringed 

 with yellow, and had blue-black tips. The props were 

 green. The caterpillars measured an inch and a half 

 in length and were rather slender. 



Two days later the dark green edges of the obliques 

 and the green of the horn changed to a purple-black, 

 showing more purple beneath the horn.
