ATTACUS GLOVERI 247 



cecropia larvae, but were longer and more slender. 

 They ate wild-cherry, refusing the common black 

 cherry and preferring the choke-cherry and the young- 

 est leaves of sapling shoots. They refused to eat even 

 the tip leaves of older trees. 



In seven days they molted for the first time. The 

 head, legs, and props were shining black. The body 

 was dull black, with shining black, spiny tubercles. 

 The dorsal tubercles were ringed with yellow around 

 their base. The horn-colored setae gave place to long, 

 stout, polished black spines. The first segment had 

 a pale yellow spot. A few of the caterpillars were 

 orange, with black dots and tubercles. 



They would eat common wild-cherry, P. serotina, 

 but much preferred choke-cherry, P. virginiana, a 

 marked contrast to cecropia mid proniethca caterpillars. 



The second molt followed in five days. The head 

 was small, greenish yellow with black marks, smooth, 

 and round. The body was greenish yellow, in some 

 cases with black dots on the dorsal line. The tubercles 

 on the second, third, fourth, and eleventh segments 

 were orange and black, in some cases almost black, in 

 others orange with black spines. The other tubercles 

 were shining black, as were the legs and props. The 

 venter was smoky black. 



They fed for but two days before molting again, 

 and grew little. The head was green with black 

 marks, the body blue-green on the dorsum and very 

 yellow-green below the subdorsal lines, marked with 

 black on the venter. There was a black line on the 

 rear of the first segment. The tubercles on the first 

 segment were all black, or pale blue with a black ring
