When attacking fruit trees the caterpillars feed upon both 
leaves and fruit, skeletonizing the former and eating irregular 
holes in the latter. (Plate XX VI, Figs. 5 and 2.) The injury to 
the fruit is quite characteristic. A shallow area is eaten out on 
one side and sometimes over a considerable portion of the fruit, 
from which one or more deep channels lead into the interior. 
Plate XX VII shows the characteristic injury to a young apple. 
The caterpillar is about to enter the channel. Favorite fruits 
for the caterpillars to work upon are those that hang so as to 
touch each other. In such cases the shallow area is often eaten 
out on both fruits and a deep channel made into each so that 
the caterpillar can pass from the interior of one directly into 
the interior of the other. In some cases very small apples may 
have nearly all the interior eaten away, the injury much resem- 
bling that of the green fruit worms. The result of such injury 
is to prevent the development of the fruit or cause it to become 
distorted. 
DESCRIPTION AND NOTES ON LIFE HISTORY. 
The egg.— The egg-laying habits of the females have remained 
amystery. So far as we have been able to ascertain there is no 
record of where the eggs are laid and no description of the egg. 
With the hope of securing some of the eggs a large number of 
moths were kept in confinement. No eggs were secured except 
in two instances. The moths that laid these eggs were kept in 
small glass bottles with a single apple leaf that had been care- 
fully examined before being placed in the bottle. After a few 
days two eggs were found on one leaf and one on another. They 
were stuck lightly to the surface and were easily jarred off. 
Two were placed on the upper and one on the under surface. 
None of the eggs hatched. In color they were pearly white, 
oblong-oval in shape, obtusely rounded at one end and tapering 
slightly toward the other. The shell was quite delicate and 
easily broken except at the smaller end where it was thickened. 
They were about uniform in size and measured 36 mm. by 
16 mm. 
The failure to secure eggs from the other moths and the fact 
that these eggs did not hatch, indicate that the conditions under
