1792 BUTTERFLIES BEYOND NEW ENGLAND. 



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. 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 off the shrunken skin, and soon assumes the delicate green color 

 marked with cream-yellow, and the elegant form which Nature has im- 

 posed upon it." (Riley.) 



According to Edwards, the egg-state lasts in West Virginia three days, 

 the successive larval stages three or four days each, or a total of twenty 

 days for larval life, the chrysalis seven or eight days ; so that all the 

 changes from egg to imago are passed within a full month. 



"Before the fourth moult the larva covers the surface of the leaf about 

 its resting place with silk, and after the moult remains quiet for nearly two 

 days, when it becomes active and feeds ravenously : the body now grows 

 rapidly, lengthening about one-tenth inch daily, till it reaches maturity, 

 five days after the fourth moult. 



"Several of the larvae of the first summer brood raised by me, in 1873, 

 stopped feeding after the second moult, and commenced their hibernation. 

 Some composed themselves on the leaves in the glass in which they were 

 kept, others directly on the sand at the bottom of the glass, in either case 

 upon a coating of silk. The color of these larvae soon changed to brown, 

 in which was to be seen, under the microscope, a mottling of vinous and 

 green. The last fall brood all assume this color, and hibernate also after 

 the second moult. And the earlier broods sometimes all hibernate, as I 

 observed last season (1874)." (Edwai-ds.) 



Limneria ftigitiva has been found attacking this insect by W. H. Ed- 

 wards in West Virginia.
