SIXTH ANNUAL REPORT 





Apatura Lycaon: 



b, larva, dorsal view; 



40, ff) rather more than an 

 w inch long, of a pea-green 

 y^*"^' jj- color, with a series of yellow 

 ' ' spots along the middle of 

 the back, and three yellow 

 lines each side, the interme- 

 diate one undulating, often 

 obsolete on the anterior part 

 of each joint, and containing 



chrysalis; dorsal and lateral views; e, imago, male, the Tii.i i j i a ^- i 



dottedlmcshowinglbi-moffemale— all natural size. a little leaa-COlOreQ dimple. 



The body is more or less thickly granulated with pale papilla, remind- 

 ing one of PapJiia [2d Rep., Fig. 94; 5th, Fig. 12]; swells in the 

 middle, from which it tapers both ways, the anal extremity ending in 

 two horns. The back and sides are flattened, the latter sloping 

 slightly, roof-fashiun. The most characteristic feature is the head, 

 which, though variable in color, is always surmounted at this age 

 with two antlers. 



This larva is found when at rest on the under side of the leaf, usu- 

 ally on a carpet of silk, and often with a portion of the leaf bent 

 around it. The lower part of the head is then drawn under the neck 

 and the antlers thrown forward (Fig. 39, J). In preparing for the chrysalis 

 state, it spins on the under side of a leaf a little bunch of silk in which 

 to entangle its anal prolegs. Sometimes, but not often, it partially 

 covers itself with a curled leaf, or with two leaves drawn together. 

 Here it rests for about two days, when the larval head and skin split 

 open, and the soft and unformed chrysalis works them back to the 

 extremity of its body. It then secures itself, knocks oflf the shrunken 

 skin, and soon assumes the delicate green color, marked with cream- 

 yellow, and the elegant form (Fig. 39, c, d), which Nature has imposed 

 upon it. Most naked chrysalides, which have the bodies appressed to 

 the object of attachment, are girded and supported by a loop adroitly 

 constructed by the larvse,* but our Lycaon chrysalis, by aid of its pecu- 

 liarly elongate anal pad of crochets running under the end of the abdo- 

 men, is enabled to retain this position without any such loop. In this 

 it differs from all the other members of its family (]V^i/m2)haUdw), which 

 simply suspend themselves by the tail, and which hang more or less 

 directly at right angles from the object of attachment, when not sup- 

 ported by leaves.
