about 18-lOOths of an inch long, and a third as broad, within 

 which it changes to a pupa. Analogy teaches us that from this 

 pupa will come a winged moth or miller, such as often flutters 

 about our candles in the evening. This moth will lay its eggs 

 upon the leaves or in the chinks of the bark of the apple treej 

 from which eggs another generation of tliese 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 marginis slightly 

 hollowed or concave; and running parallel with the anterior 

 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 ^rgyro-lapia, and 

 the sub-genius Lozopera of the distinguished British Entomologist,. 

 Mr. Stephens ; and as this species does not appear to have beea 

 hitherto described, I propose to call it the Jirgyrolepia pomarianay 

 the specific name being derived from the Latin, /xwiarzttm, 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 Jir- 

 gyrolepia.
