The eggs are in the form of a truncated cone, and attached by the 

 smaller end, while the other end has a dark rim with a depressed 

 center, Fig. 3, a and b. These hatch in the spring at about the same 

 time as the other species, and the larvae have similar habits to those 

 of the spring species. 



The mature lai-vae are nearly an inch long, varying in color from 

 a greenish yellow to dark brown, with pale stripes running length- 

 wise ; and they differ from the other species still further in having 

 three pairs of abdominal legs, Fig. 3, /. After they are done 

 feeding, they descend from the trees and burrow into the ground 

 where they pass their transformations, and the moths emerge late in 

 th« fall.

The males have well developed wings which expand nearly an inch 

 and a half, and are of a pale gray or ash color. The forewings have 

 two rather irregular whitish bands across them, and the hind wings 

 have a faint blackish dot on the middle and a more or less distinct 

 whitish band outside of it. Fig. 4, a. The females are pale gray or 

 ash color and about three-tenths of an inch long. Fig. 4, h. 



REMEDIES. 



As the females are wingless and pass their transformations under 

 ground, and are obliged to crawl up the trunks of tie trees to deposit 

 their eggs, one method is to prevent their ascent by putting bands of 

 heavy paper around the trunks, and painting them with some sticky 

 preparation, as printer's ink, or tar softened with oil. 



Another method is to put a trap of zino or tin around the trunks 

 of the trees in such a manner as to prevent the females from 

 ascending the trees. Care must be taken in putting the bands and 

 traps around the trees, to have tb2m fit so tightly that neither the 

 female moth nor the newly-hatcher' larvae can find a passage beneath. 



Probably the most effectual method is to shower the trees with 

 paris gr«en in water as soon as the eggs have hatched in the spring.
