Glover’s account of their working downward in the old twigs from the 
terminal buds before the starting of the leaves in April apparently 
can not be questioned, but seems not to be the normal course, as shown 
by the observations since made. 
In our experience, the larve begin to migrate only after the new 
foliage has begun to put out,and they attack the new shoots at any 
point, generally, however, from one-half inch to an inch from the apex, 
eiiher 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 
the entrance, and occasionally the larve simply eat into the shoot as far 
as the pith and then go elsewhere. The larvie are seemingly restless 
and not easily satisfied, and are continually moving from one shoot to 
another, aud 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 observa- 
tions on the habits of the larve in 
the young shoots are slightly at 
variance with the above. He says 
the larve puncture the shoots at 
the base, eating them off com- 
pletely, the severed twigs remain- 
ing attached to the branch by the 
guminy substance which exudes 
from the wound. This particular 
form of injury we have not noted.

new growth the larvie bores rather [then fom attacks of baw: B larva em 
rapidly, sufficiently so at least to 
excavate a burrow two-thirds of its length in an hour. The length of 
time spent by the hibernated larve in coming to full growth in the 
green shoots is comparatively short, not exceeding ten to fifteen days. 
In California and also in Washington the larvie begin transforming to 
pup in the latter part of April, and the moths of the first brood emerge 
throughout May. 
The adult larva tapers strongly toward either end, and attains a 
length of three-eighths to a half-inch, or slightly more when in motion. 
It is of a dull reddish-brown color, the reddish color predominating 
before maturity and the latter after maturity, and the head, and the 
cervical and anal shields are dark brown or almost black. The space 
between the segments is noticeably light-colored, and especially between 
the second and third thoracic segments. The hairs are long and spring 
singly from minute tubercles. . Other details of structural features are 
shown in the illustration (fig. 2 )). 
In confinement the larva on reaching full growth spins a seanty web,
