here were almost denuded cf foliage. The arsenate of lead spraying 
is very effective for this: the few trees sprayed last year were the 
least infested. The peculiar phase about this insect with us is 
that we have found it only on plane' trees. In Highland Park, where 
basswoeds , crab apples, maples, and elms are nearby and touching 
the plane trees, they are found almost entirely on the plane trees, 
which are badly eaten. It seems strange that this is reported as 
a general feeder. The weather this summer is exceptionally cool 
and as a rule insect pests are much less noticeable than usual.
