ance of the one shown at Plate XL, Fig. 2, and by the second 
day all were drawn over as shown at Fig. 3. The caterpillars 
thus roll the leaves in a manner somewhat similar to a true leaf 
roller. They evidently feed for a time in these retreats before 
pupating, as out of a large number examined the parenchyma on 
the upper side was entirely eaten away in most cases. 
Before pupating the caterpillars line their retreats heavily with 
white, closely woven silk. Every one examined both in the labora- 
tory and in the orchard was lined in this way. The silk is not 
closely attached to the leaf except at the edges which are fas- 
tened together and to the leaf tissue. Within this snug retreat 
the chrysalis is formed. At Plate XL, Fig. 4, the edges of the 
leaf that were drawn together have been pulled apart, exposing 
the white, cocoon-like covering of the chrysalis. In this stage 
the insect evidently passes the winter, although it is probable 
that some of the larve hibernate, as Forbes® states he has found 
them as late as the middle of November. Our own observations 
are similar to those of Forbes,as we found hibernating larve

Length 5.5 mm, to 7 mm. General color light greenish drab to slate. 
With the exception of the first, each segment has eight dull white slightly - 
raised blotches, four on each side of the median line. Hach bears one or 
two slender white hairs. Head half as broad as first segment, light yellow- 
ish green to light brown. Mouth parts brown. Along the posterior mar- 
gin of the head is a row of six large deep black irregular spots. The two 
end spots are sub-marginal, triangular and slightly larger than the others. 
There is also a somewhat paler spot at the base of each mandible. A row 
of four similar spots extends across the first segment midway between the 
anterior and posterior margins. The spots are larger than those or the 
head. Thoracic, abdominal, and anal legs well developed. Outer surface of- 
thoracie legs black and smooth. Inner surface same color as ventral sur- 
face ef body and sparsely furnished with hair.
