the fact of its being lined with silk precludes the idea that the larva 
feeds in the fall or during hibernation, except perhaps in the mere oper- 
ation of excavating the chamber. 
The young larva, as taken from the burrow, is not above 2 milli- 
meters long, and is of a general yellow color, w the head and cer ‘vical 
and anal plates dark brown, almost black (fig. 1, ¢). 
While in their winter “neta the larvie are subject to the attacks 
of predaceous mites, and many of them are destroyed by this means, 
as will be later noted. They are also occasionally parasitized by a 
chaleidid fly. 
Early in April the larve begin to abandon their hibernating quarters 
and attack the new leaf shoots, but some individuals were found in the 
crotches by Mr. Ehrhorn as late as April 21. The damage becomes 
noticeable, as a rule, at the time the shoots are from one-half inch to 2 
inches in length, or, more properly 
speaking, mere clusters of newly 
expanded leaves. 
Glover’s account of their work- 
ing downward in the old twigs 
from the terminal. buds before the 
starting of the leaves in April ap- 
parently can not be questioned, 
but seems not to be the normal 
course, aS Shown by the observa- 
tions since made. 
In our experience, the larvie be- 
gin to migrate only after the new 
foliage has begun to put out, and a

apex, either near or in the crotch 
formed by the leaf petiole and the stem. The longest burrow observed 
was 14 inches and the shortest one-fourth inch. Sometimes the burrow 
extends about one-eighth inch above the entrance, and occasionally 
the larve simply -eat into the shoot as far as the pith and then go 
elsewhere. The larve are seemingly restless and not easily satisfied, 
and are coutinually moving from one shoot to another, and are most 
active travelers. In this way a single larva may destroy or injure 
several shoots before reaching maturity, thus greatly increasing the 
damage. 
Professor Comstock’s observations on the habits of the larve in the 
young shoots are slightly at variance with the above. He says the 
larvee puncture the shoots at the base, eating them off completely, the 
severed twigs remaining attached to the branch by the gummy sub- 
stance which exudes from the wound. This particular form of injury 
we have not noted.
