AMPHION NESSUS 81 



instead of green, and one was of a clear wine-color, 

 with the obliques and other body-lines of pink edged 

 above with deep claret-color. The granules and face- 

 lines were pale yellow. Some larvae had ten obliques. 

 Some had no pink on the abdominal props. 



All were more sluggish in this stage and the next 

 than any other larvae we have reared, and were most 

 easily detached from the vine, the slightest jar suffi- 

 cing to send them to the ground. If removed from a 

 twig and laid on their backs, they did not even turn 

 over until they were hungry and had to crawl to a leaf 

 to feed. 



The fourth molt followed four days later. All came 

 out pale brown granulated with yellow, each granule 

 having a black dot in its center. The head was bi- 

 lobed, dark brown between the yellow face-lines, rough 

 with black and a few pale yellow granules. Outside 

 of the face-lines the granules were yellow. The body 

 was dotted with black. On the thoracic segments were 

 black dorsal, subdorsal, lateral, and stigmatal lines, 

 the dorsal line being represented on the abdominal 

 segments by a black patch at the juncture of every 

 two segments. The obliques were distinct and almost 

 black — nine in most instances, ten in a few. The 

 horn was very short, stout, and rough. The spiracles 

 were black, with a yellow dot at each end, and encircled 

 by a yellow line. The legs and props were brown, the 

 anal props being darker than the others, and the anal 

 shield was of this darker brown, with a dorsal line ex- 

 tending to its tip and a yellow edge. The third and 

 foiu-th segments were slightly swollen — just enough 

 to be out of focus in the photograph.
