tree was observed, wholly stripped of its leaves, save merely a 
few fragments upon some of the lowest limbs; and at every step 
taken among the weeds and grass growing beneath this tree, a 
swarm of these moths would arise. An inspection of the several 
specimens in my possession shows that no two individuals are ex¬ 
actly alike in all their details. The general color of the fore¬ 
wings varies from tarnished cream-white to dark ash-gray, often 
with a pale purplish-red reflection, and mottled more or less 
with darker cloud-like spots of tawny yellowish-brown, which 
spots sometimes form four equidistant transverse bands There 
are often two larger black dots slightly forward of the middle 
of the wing, and two others half way from these to the tip; 
but these dots are sometimes indistinct or wholly wanting. The 
seven black dots in a semicircular row, at the base of the termi¬ 
nal fringe, are almost always present. The veins of the hind- 
wings are commonly darker than the general surface; the fringe 
is of the same color or sometimes lighter. 
Associated with this species, both in our orchards and forests, 
may frequently be met with another moth of the same size and 
general appearance, and with its bodyand wings similarly colored 
and dotted, but having only the outer or costal half of the fore¬ 
wings of a dull cream-white or ash-gray color, whilst the inner 
half, the whole length of the wing, is of a brownish-black, the 
one color not shaded gradually into the other, but the transition 
being abrupt. I have named this the Comrade Moth, Chcetochilus 
contubemalellus, from the latin contubernalis, a comrade. The 
worms which this moth breeds, doubtless infest the apple and 
other trees the same as those of the other species. As already 
intimated, I propose preparing a full account of these insects, at 
an early day. A. F. 
Note. —A gentleman of Albany, who has a farm a short dis¬ 
tance from town, discovered these worms upon his apple trees, 
having destroyed the leaves upon two trees. He procured some 
whale oil soap, diluted it with water, and with a garden engine 
thoroughly drenched the remainder of his trees, and they were 
entirely preserved from the ravages of the worms. J.
