surrounding the hind legs. It expands .65 of an inch. The 

 larvffi, received from Mr. M. C. Reed, of Hudson, Ohio, were 

 pale green, with a greenish yellow head. Along the body is a 

 double d jrsal paler line, and whitish tubercles, from which pro- 

 ceed very long uneven hairs, and the bod}' is also covered with 

 very short white hairs, giving a frosted appearance to the 

 worm. They are about half an iiich long. About the middle 

 of June it changes to the singular chrysalis represented on the 

 plate, and in about a fortnight appears as one of the most deli- 

 cate and graceful of moths. It may be seen flying about our 

 graperies in midsummer, and is attracted to our apartments 

 after nightfiiU by the lights within. It feeds upon the young 

 leaves of the grape, hiding itself in a hollow ball made of 

 leaves drawn together by threads. The pupa is slender, coni- 

 cal, obliquely truncated at the head, with two long compressed 

 horns placed side by side, and jutting upwards from the mid- 

 dle of its back, and numerous smaller projecting points and 

 ridges. It reminds one of the chrysalids of the butterflies, 

 in its habit of remaining attached by its tail to the plant on 

 which it feeds. 



In Alucita the wings are still farther subdivided, each wing 

 being divided from the base into six distinct feathers. The 

 larva of the European A. j)ohjdactyla feeds in the unopened 

 buds of the honey-suckle. It is not hairy, and spins a co- 

 coon.
