which it pertains, followed by a brief statement of (1st) the par- 

 ticular injury which each species does and the time of the year 

 when it commits its depredations, (2d,) the appearance of the 

 depredator, and if it be a worm or larva, add to this (3d) where 

 it secretes itself to repose during its pupa state, and (4th) the 

 appearance which it finally assumes when it comes out in its per- 

 fect form; and if it be a species the history of which has already 

 been published, give (lastly,) a reference to the work where 

 the most particular account of it and the remedies for opposing it 

 will be found. I endeavor in each instance to render this account 

 as succinct as possible, and at the same time sufficiently plain and 

 definite to enable any one, when he meets with an injurious insect, 

 to ascertain its name. As it is the leading design of these Reports 

 to impart information to common readers, I aim to use such terms 

 and give such comparisons as will make the subject most clear to 

 their comprehension, even at the risk in some instances of appear- 

 ing inelegant and uncouth. 



Many insects, it is well known, feed upon several different 

 kinds of vegetation. The account of these is introduced under the 

 particular tree or plant to which each appears to be most attached 

 and on which it occurs in the greatest abundance, and under eacli 

 of the other trees or plants on which it is known to feed, its name 

 only is given, with a reference to the place where tlie descrip- 

 tion of it will be found, the species being numbered in a continuous 

 series to facilitate such references. A large portion of the insects 

 whicli now infest our fruit trees, originally subsisted upon the 

 native forest trees of this country, and many of these still occur 

 in their original haunts in greater numbers than in the new situ- 

 ations to which circumstances have obliged them to resort. Eut 

 as such insects will be much more frequently noticed upon fruit 

 trees, and are more important to us in consequence of the depre- 

 dations they are liable to commit upon the trees of this class, I 

 place the description of them under this head. The present Report 

 thus ci)mi)lett'S the account of all the insects at j)resent known to 

 infest our fruit trees, both cultivated and wild, the latter embracing 

 the chestnut, hickory, butternut and hazelnut, which 1 class as 

 fruit rather than forest trees, for the reason that they are more 

 valued through our country generally, in consequence of the fruit
