A slender pale yellowish worm with a tawny yellow stripe along each 
side of its back, this stripe having a whitish stripe upon its lower as 
well as its upper side, and a pale yellow head; residing in the fold of 
a worm-eaten leaf, the fore part of July. 
The tawn y-stkiped palmer-worm, Chmtochilus Malif nliellus , new species. 
A similar worm, but having a shining black head and neck; residing in 
a similar situation, the latter part of June. . 
The comrade palmer-worm (probably), C. contubernalellus, Fitch. 
In addition to the common Palmer worm, described in the pro¬ 
ceeding pages, other worms very similar to it in their appear¬ 
ance, motions and habits, and pertaining to the same genus of 
moths with it, are occasionally met with upon the leaves of ap¬ 
ple trees. One of these I have noticed in different years, the 
fore part of July, at which time the common Palmer worm has 
nearly or quite disappeared. It is rather more narrow and slen¬ 
der than that worm but is otherwise like it in form and size. 
The stripes along each side of its back, however, are of a tawny 
yellow color, instead of dusky or blackish, and it has a pale 
stripe along the lower as well as the upper side of this dark 
stripe. It appears to be even more agile than that species, when 
disturbed wriggling and throwing itself about with lightning- 
like velocity. 
One of these worms which I met with in an apple leaf which 
it had folded and tied together with silken threads was placed in 
a large mouthed vial. Three days afterwards it had eaten the 
whole of the leaf except its mid-vein, under which and some 
fine threads which it had spun, it remained concealed. Two 
fresh leaves were now put into the vial, July 4th. Forsaking 
its former domicil the worm now took up its abode in one of 
these leaves, which it folded neatly together, with the edges ex¬ 
actly adjusted to each other and securely sewed in their places. 
Here entirely hid from view it ate but little more before enter¬ 
ing its pupa state, from which the perfect insect was obtained 
on the twenty-fifth of the same month. The accompanying fig¬ 
ure is designed to represent the manner in which 
these different species of Palmer worms draw r the 
leaves around them, tieing them together with 
fine silken threads and gnawing them more or 
less. The pupa also lies within these tufts of 
worm-eaten leaves, and when ready to disclose
