An account is first given of the particular injury which each 
species does to the vegetation which it infests ; to this succeeds a 
description of the inseot itself, in the different stages of its exist¬ 
ence, and finally an account is presented of the remedies by 
which the insect can be destroyed, or the plant and tree which it 
infests shielded from its attacks. The whole is couched in plain, 
familiar language, perfectly intelligible to the general reader, and 
giving a dear and distinct view of each topic discussed. It ^in¬ 
tended also, to illustrate by wood cuts and engravings, the mode 
in which the leaves, wood, &c., are gnawed or otherwise injured, 
by each particular species, with figures of the insect in different 
stages of its life. A number of the insects whose history is given 
in the report, have never been named ami described before, al¬ 
though occasional notices of the injuries done by some of them 
have appeared in our agricultural periodicals ; and of the species 
before known, the account here presented has been principally 
drawn from original observations. 
These observations frequently show that the accounts previously 
published, even of some of the most common and injurious spe¬ 
cies, are imperfect, and in some instances so inaccurate, that intel¬ 
ligent nurserymen, farmers, and editors of agricultural papers, 
have sometimes been misled, and have pronounced certain depre- 
datorsto be a new and undescribed species. The full and thorough 
examination that has been given to several of these species, has 
led to the discovery of new and more efficient means for subdu¬ 
ing them. For instance, the mode here pointed out for detecting 
and destroying the apple tree borer, is so simple, and obviously so 
effectual, that we doubt not, upon the publication of this report, 
it will immediately attract notice, and will supercede all the 
modes which have hitherto been employed for destroying this 
most pei nicious insect. And your committee are of the opinion, * 
that the able and interesting account which is here given of this 
insect, will induce thousands of our orchardists henceforth to be 
on the alert, and save their trees from this pest, now shown to 
be so common, and thus annually save to our State, fiom the 
depredations of this one insect, an amount much exceeding the 
•sum required to continue these investigations.
