264 REPORT OF THE DEPARTMENT OF ENTOMOLOGY OF THD 
Two species of apple leaf miners were unusually common in 
Western New York orchards, but caused little injury as they do 
not appear until late in the season. 
Peaches in an orchard near Rochester were injured by the 
tarnished plant-bug, which sucked the juice from the young 
fruits, causing them to wither and become permanently distorted. 
I. THE FOREST TENT-CATERPILLAR, 
Clisiocampa disstrva Hubn. 
The forest tent-caterpillars appeared again last spring in-suf- 
ficient numbers to cause much annoyance, and in some cases 
serious loss. The questions as to whether the caterpillars appear 
to be increasing or decreasing in numbers, taking the State as a 
whole, and whether they are becoming more destructive to 
orchard trees are of importance to fruit growers. To Secure 
data bearing on these questions, circular letters were sent, as 
last year, to correspondents in nearly every county in the State. 
Summing up the reports and adding our own observations, the 
extent and character of the outbreak were approximately as 
follows: In most of the western Counties the caterpillars were 
widely scattered, the same as last year. In Allegany and Steu- 
ben Counties, they were less in numbers, as a rule, in the inaple 
groves, woodlands and orchards that were extensively infested 
last year; but much more abundant in neighboring localities in 
which they appeared in less numbers the year previous. The 
reports from Cortland, Chenango, Madison, Oneida and Herkimer 
Counties state that the caterpillars were usually more numerous 
in the forest trees and orchards than last year but less in num- 
bers on shade trees. The reports from Herkimer County indi- 
cate that in that section they were somewhat less abundant 
in forest trees, but more numerous in orchard trees. Similar 
reports came from Saratoga and Washington Counties and the 
Mohawk and Upper Hudson valleys. In the northern part of 
the State, especially St. Lawrence, Franklin and Clinton Coun- 
ties, there is a reported decline in numbers.
