burn them with their inhabitants. This advice it may be proper 

 for us to follow, although it is not yet certain that our turpentine- 

 moths are actually the same as those of Europe. 



Among the insects, that have been brought to America with 

 other productions of Europe, may be mentioned the apple-worm, 

 as it is here called, which has become naturalized wherever the 

 apple-tree has been introduced. This mischievous creature has 

 sometimes been mistaken for the plum-weevil (Rhynchctnus Co- 

 nolrachelus Nenuphar), described in another part* of this essay ; 

 but it may be easily distinguished therefrom by its shape, its hab- 

 its, and its transformations. Although the plum-weevil prefers 

 stone fruit, it is sometimes found in apples also ; and Dr. Joel 

 Burnett, of Southborough, Massachusetts, has lately sent to me 

 specimens of plum-weevils, in the pupa state, raised by him from 

 grubs in apples. On the other hand, the apple-worm has never 

 been found here in plums. It is not a grub, but a true caterpillar, 

 belonging to the Tortrix tribe, and in due time, is changed to a 

 moth, called Carpocapsa Pomonella], the codling-moth, or fruit- 

 moth of the apple. An anonymous writer, in the "Entomologi- 

 cal Magazine "| of London, has well remarked that this moth " is 

 the most beautiful of the beautiful tribe to which it belongs ; yet, 

 from its habits not being known, it is seldom seen in the moth 

 state ; and the apple-grower knows no more than the man in the 

 moon to what cause he is indebted for his basketfuls of worm- 

 eaten windfalls in the stillest weather." 



Before proceeding to a description of this insect, it may be 

 proper to state some facts respecting the habits of the plum-wee- 

 vil, that were omitted in the foregoing part of this essay, with 

 others that have recently come to my knowledge ; for, by means 

 of these, the difference between the two insects will be made 

 more clear. It must be borne in mind that this plum-weevil, an 

 insect unknown in Europe, when arrived at maturity, is a little,

 nus be correct, it was probably formed from two Greek words signifying to devour 

 fruit. Perhaps the name should have been Carpocampa, that is, in English, fruit- 

 caterpillar.
