are given out tiifts of ^v^y hairs mingled with white ones which are 

 clavate at the tip ; the h^teral fringe with nuinerons gray clavate hairs. 



Legs black ; prolegs ash-color, with a black spot between each pair. 



The caterpillar made its slight cocoon between two leaves, envelop- 

 ing it in a wool like substance. Another example, occurring on 

 maple, spun up between some leaves on September 12th. 



It is quite liable to parasitic attack. A pupa which did not develop, 

 was opened, and found to contain the puparia of nine Tachinse. 



Clisiocampa Americana {Fah\). 



Some larvae of this species which made their cocoons on the 6th of 

 June, completed their transformation and appeared as moths on 

 July 6th. 



Young larvae have been observed, just disclosed from the egg-belt 

 on the 18th of April. 



(ZYG^NID^.) 

 Ctenucha virginica {Charp.). 



Larva taken on grass, upon which it may be presumed to feed, as 

 it has also been found thereon by Dr. Packard, in Maine. Head 

 large, shining black. Body reddish-brown dorsally, darker shaded 

 on the incisures, black laterally, wnth two light cream-colored stripes 

 on each side; its short, brush-like fascicles of hairs proceeding from 

 tubercles and nearly covering the body, are black on the back, and 

 dusky and black intermingled on the extremities and sides ; inter- 

 mediate ones (?) ochre-yellow. 



An imago was obtained June 4th from a cocoon found a few days 

 previously, attached to the leaves of a cedar seedling, about two 

 inches above the ground. 



The cocoon is oval, .75 in. in length, composed of the hairs of the 

 caterpillar, which are gray and black, and about one-fourth of an inch 

 long, and, under a lens, show distinct feathering. Through the hairs 

 could be seen the inclosed dark brown pupa. 



The moth has frequently been observed in a grove of pines and 

 cedars at Schoharie, in 1859. It is not readily alarmed when at rest, 

 and its flight is slow and steady, permitting its easy capture. It 

 was unusually abundant in 1861, at the same locality, being fre- 

 quently seen about dwellings and in gardens. On the 23d of June 

 numbers were observed in a ravine, beside a brook bordered with 

 deciduous trees.
