REPORT. 
[OOrY-RIOHT SECURED TO TH* AUTHOR.] 
Executive Committee of the New- York State Agricultural Society: 
I herewith submit a Report upon the Noxious and other Insects 
of the State of New-York, particularly such as are injurious to 
fruit trees, pursuant to your instructions, delivered to me in May 
last. I also present specimens of the several insects herein 
described, and of the vegetation as depredated upon by them, 
from which drawings may be taken for illustrating this report, 
and which are thereafter to be deposited in the Entomological 
department of the Museuih of the Society. 
It has been common in treatises upon economical entomology, 
to arrange the several species in their scientific order. Although 
this mode of arrangement has its advantages, it presupposes such 
an acquaintance with scientific entomology as but very few indi¬ 
viduals in our country possess. A person who meets with a 
worm, say, mining a cavity in the leaves of the apple tree, and 
consuming their parenchyma, knows not whether that worm is the 
larva ot a Coleopterous, a Lepidopterous, or some other Order of 
insects, and consequently, is at a loss in what part of a work upon 
noxious insects, arranged in the usual manner, to lock for an 
■account of it. Even an experienced entomologist would be 
equally embarrassed in the case we have supposed, and would be 
unable to decide whether such worm was a leaf-mining moth of 
the Order Lepidoptera, or a Prickly beetle [Hispa) of the Order 
Coleoptera—so closely, according to accounts, do the larvae of
