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 each 
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 the 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 
which 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. But 
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 completes the account of all the insects at present known to 
infest our fruit trees, both cultivated and wild, the latter embracing 
the chestnut, hickory, butternut and hazelnut, which I class as 
fruit rather than forest trees, for the reason that they are more 
valued through our country generally, in consequence of the fruit
