DEILEPHILA LINEATA 97 



dorsal line from the now black horn half-way to the 

 head, giving a pinkish appearance to that part of the 

 body. A few had the first five or six segments notice- 

 ably pinkish, and all looked black-striped from the 

 rows of black setse — without a lens. With a glass 

 the set£e showed clearly. Next day their heads were 

 the color of old ivory, and their bodies had almost as 

 glassy an appearance as those of young T. ahhot'ii 

 larvae. 



The first molt came on the eighth day and changed 

 the caterpillars somewhat, besides the increased 

 length. Their heads were smooth, orange-brown, and 

 bilobed. Their bodies were dark green speckled with 

 lighter green. On the dorsum of the first segment 

 was a divided horny plate of lighter green. A faint 

 yellow stigmata! line showed on the first three seg- 

 ments, and there was a bright yellow subdorsal line. 

 The legs and props were lighter green, and the horn 

 was light green at base, black and rough above. 

 Some had no yellow lines. In some the anal shield 

 was orange-brown. 



In four days they molted again, being now half an 

 inch long, with no setse. The orange-brown head was 

 speckled with a lighter shade. The body was almost 

 black, rather faintly speckled with yellow- white. A 

 bright yellow subdorsal line extended from head to 

 horn, and on it, on each segment, was a yellow patch. 

 There was a stigmata! wavy line of bright yellow. The 

 spiracles sliowed yellow-white. The horn was orange- 

 brown at base, black and rough above. The body 

 tapered from the third segment to the head. In tliis 

 stage they ate woodbine much better tlian grape,
