the winged moth it crowds itself partly out from between them, 
in which situation the empty shell remains after the moth has 
evacuated it. At the upper left-hand corner of the figure the 
relics of the pupa are represented, protruding in this manner 
from between the leaves. 
The larva when full grown is half an inch long and about 0.06 in diameter, 
composed of thirteen segments, distinctly marked by strong wide contractions 
at each of the sutures. The last segment is divided into two parts by a su¬ 
ture across its middle. The body is slightly flattened and of a pale tawny 
yellow color above, with two stripes upon the back and one along each side 
of a white or yellowish white color. Below the lateral white stripe the body 
on the sides and beneath is pale watery yellowish. Upon the back the edges 
of the segments are yellowish white, and on the hind part of each, outside of 
the white dorsal stripes is a polished black dot, from which arises a fine hair. 
A few other hairs are scattered symmetrically over the surface, arising from 
small faint dots. The head is flattened, slightly shining and of a paler yellow 
color than the body, with the antennae and the tips of the feelers dusky. The 
neck has five or six dark brown dots each side, irregularly placed and some of 
them slightly confluent. 
The moth is very similar to that of the common species, from which it may 
be distinguished, however, by its fore wings being destitute of any black or 
darker colored atoms. They are ash-gray and glossy, often with a purplish 
red reflection, with a row of equidistant black dots on the apical edge at the 
base of the fringe. Forward of the tips is a dull tawny yellow band margined 
on its anterior side with dull white. Two dots behind and two forward of the 
middle, placed as they arc in the common species, are also of a dull tawny 
yellow color margined anteriorly with dull white, sometimes these dots are 
confluent, forming two short oblique stripes. The expanded wings measure 
0.65. 
The common Palmer worm is so variable both in the larva and 
the perfect stages of its life, that I am not without suspicions 
this may be merely a variety of that species. But as it is later 
in the season in making its appearance in each instance where I 
have met with it, and is differently marked in its larva as well 
as its perfect state, I am induced to regard it as a distinct spe¬ 
cies. 
Associated with the Palmer worms on apple and also on forest 
trees are found worms which are in all respects like them, ex¬ 
cept that the head and the upper side of the neck or second seg¬ 
ment is black and highly polished, the neck having a slender 
whitish line on the middle. Though I have not succeeded in 
breeding any of these it is quite probable they are the progeny 
of a moth which may occasionally be met with in company with 
that of the Palmer worm, and which I named C. contubernalellus
