NOTES FOR THE, YEAR 
The season has been remarkable for the scarcity of the apple 
tent caterpillar and the same has been true to a large extent of shade 
tree insects. The elm leaf beetle, presumably on account of the 
relatively cool spring and summer, caused very little injury. 
The marked scarcity of early leaf feeders observed both this 
season and last was offset to some extent by the abundance of late 
leaf feeders which was particularly marked in the case of the red- 
humped and yellow-necked apple worms noticed below, and to a 
less extent than last year, in the case of hairy caterpillars, such as 
those of the hickory tussock moth and its associates. 
A number of the more important or unusual insects attracting 
attention during the year are briefly noticed below. 
FRUIT INSECTS 
Yellow-iiecked and red-humped apple caterpillars. (Datana 
ministra, Drury ‘and Siehaziaa ‘clon cirmmas smenand 
Abb.). The yellow-necked and red-humped caterpillars, specially 
the former, have been exceptionally abundant and injurious, par- 
ticularly in the upper Hudson valley. These insects were unusually 
numerous in 1917, and appear to have been much more abundant 
the past season. The first reports of injury were received toward the 
last of June and related to small, red-humped caterpillars feeding 
upon young trees in Greene county. Injury continued so that
