thin paper, attached to the trunk or a limb of the tree upon which 
the larva fed. The chrysalis is dark brown and very smooth. The 
moth makes its appearance early in September and is a night-flyer, 
occasionally attracted to lighted lamps. Its colors are soft and 
blended, being white shaded with blue-gray, and its wings crossed 
by two broad bands of dark gray. The female moth expands two 
and one-half inches, but the male is smaller, expanding but one and 
one-half inches. 
Another species, closely related to the preceding but smaller, is 
Tolype laricis, which lives on the larch. Its larva is brownish-gray 
in color and about an inch and a half long. Its habits are much like 
Tolype laricis. 
T. velleda, and it makes a similar though smaller cocoon. The moth 
emerges early in September and lays its eggs, which do not hatch 
till the folowing spring. The female moth resembles 7. velleda in 
color, except that it is hghter near the body, and the outer gray band 
on the forward wings is darker and narrower. The male, which is 
here figured, is dark gray with clouded wings. The abdomen is 
sooty black. According to my experience this is a rare moth. 
Gastropacha americana. 
Gastropacha americana is a reddish-brown moth with a lighter 
band crossing the wings, edged with wavy dark brown lines and 
having the edges of the wings scalloped. There is a good deal of 
discrepancy in size between the male and female, a good-sized speci- 
men of the latter spreading two inches. The larva feeds on apple, 
birch, maple and ash. It is flattened beneath and fringed with hairs
