To the Regents of the University of the State of New York 
I have the honor of presenting herewith my report on the 
injurious and other insects of the state of New York for the year 
ending Oct. 15, 1901. 
General entomologic features. The forest tent-caterpillar, Clis- 
iocampa disstria Hibn., as was predicted last year, has, 
generally speaking, not been nearly so injurious the last season, 
though in places here and there in the state, it has inflicted 
considerable damage. Its abundance in orchards adjacent to 
woods badly infested the previous year was a somewhat char- 
acteristic feature of the attack this season. The common apple- 
tree tent-caterpillar, Clisiocampa americana Fabr., has 
also been abundant in different sections of the state, but it has 
not been specially injurious as a rule. The white marked tus- 
sock moth, Notolophus leucostigma Abb. & Sm., has 
been quite harmful to the shade trees of Buffalo. The destruc- 
tive work of the elm leaf beetle, Galerucella luteola 
Miill., has been continued in the Hudson river valley, and in its 
northern part this insect has succeeded in extending its range 
to a number of villages previously infested with very few or 
none of these pests. The fall web worm, Hyphantria 
cunea Drury, has been exceedingly abundant in portions of the 
southern part of the valley and near the western end of Long 
Island. The depredations of the Hessian fly, Cecidomyia
