from which eggs another generation of these worms will be hatch¬ 
ed. Dry, hot weather, in the month of June, it is certain, favors 
the multiplication of these worms. Before they were observed, 
it was currently remarked that such a spell of sultry, dry weather 
as we then had, was never before known so early in the season. 
On the night of June 23d we had heavy thunder showers, and the 
next day few of these worms could be found upon the trees. And 
though they are still present (June 30th) their numbers are now 
greatly reduced. Query—will not drenching the trees with wa¬ 
ter from a garden or fire engine prove to be the most effectual 
way of ridding them of these worms. 
On beating and shaking the apple trees, I have repeatedly seen 
a moth fly from among the leaves, which I have little doubt is 
the parent of these worms. It is a delicate, pretty little insect, 
measuring six-tenths of an inch across its wings when they are 
spread. Its fore wings are of a shining pale yellow color, coarsely 
freckled with darker orange-yellow spots. The hind ends of its 
wings are occupied with a broad band of a purple color, blended 
with orange, and towards the outer or costal edge with a pale 
yellow. This band is double the width upon the costal that it is 
upon the inner side of the wing, and its anterior margin is slightly 
hollowed or concave; and running parallel with the ariterior 
margin is a curved stripe, of ,an orange color, often tinged with 
purple, extending across the wing, slightly forward of its middle. 
The hind wings are grayish-brown, and white anteriorly on the 
outer side. This moth pertains to the genius Argyro-lapia, and 
the sub-genius Lozopera of the distinguished British Entomologist, 
Mr. Stephens; and as this species'does not appear to have been 
hitherto described, I propose to call it the Argyrolepia pomariana , 
the specific name being derived from the Latin, pomarium, which, 
translated, will give us for the common name of this insect, the 
Orchard Moth , or, if we wish to be more definite, the Orchard Ar- 
gyrolepia. 
Our forests at present are infested to an unusual extent with a 
worm so exactly like that in the orchards, that every body regards 
them as being identical; nor have I been able to detect any marks 
by which they can be told the one from the other. Still, it is
