bluish-gray above and somewhat mottled; with transverse scarlet bands 
on the back, one on the second and one on the third thoracic segments, 
and in each of the bands are three black dots. This species is quite gen- 
erally distributed through the eastern part of the United States and 
southern Canada. The larvae feed on the foliage of aspen, wild cherry, 
hickory, oak, and other deciduous trees. There is one generation in the 
northern part of its range 
and at least a partial sec- 
ond generation farther 
south. It is often found 
by collectors but never re- 
ported as very common. 
The moths emerge in 
May and June and in 
July, the larvae may be 
found.from May to Au- 
gust, and the winter is 
passed in the pupal stage 
in tough flattened co- 
coons, usually on the 
bark. 
Famiry ZANOLIDAE 
The family Zanolidae 
is represented in North 
America by one genus 1n 
which there are only 
three species. The moths 
resemble the Notodonti- 
dae, but they differ in 
lacking maxillae. The 
two species here treated 
are more or less common 
in the Eastern States.

marked by a row of black spots more or less connected to form a line. 
There is also a lateral row of black spots, and the dorsal sutures are 
black. The body is densely clothed with long, fine, white or yellow 
hairs, and from the second and third thoracic and the eighth ab- 
dominal segments arise long pencils of hairs, pale at the base and 
black at the tip. This species is distributed throughout the eastern 
part of the United States. Its food plants include blackberry, wild 
cherry, speckled alder, maple, and various other trees and shrubs. The 
moths emerge in June and July, the larvae may be found from June
