This description applies with sufficient exactness to the insect, 

 which, however, is subject to great variety. I have a host of 

 specimens before me, reared from the worms, and captured upon 

 the wing every where in our orchards and forests, since the first 

 week of the present month. On the 8th inst., a large white oak 

 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 body and wings similarly colored 

 and dotted, but having only the outer or costal half of the fore- 

 wings of a dull cream-wliite 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, Chmlochilus 

 conlubernalellus, 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.

 tance from town, discovered these worms upon his apple trees,
