Monroe County — Rochester, Brighton and vicinity in limited 

numbers. Wayne County — Lake Side, not abundant. Ontario 
County — Geneva and in limited numbers throughout the County. 
Seneca County — Waterloo. Although few definite reports were 
received from the extreme Western counties, it is not improbable 
that the caterpillars were to be found scatteringly at least through- 
out the western part of the State, as the conditions would be very 
similar to those in the western New York counties where they were 
observed. 
FOOD PLANTS. 
The early references to the food-plants of this insect indicate 
that it was most destructive to maples, oaks and elms. Later 
observers have recorded a large number of species of trees, shrubs 
and vines. The most complete list of food-plants is given by 
Weed.’* These represent sixteen families as follows: Rosaceae, 
apple, plum, hawthorn, mountain ash, cherry; Hamamelidaceae, 
sweet gum; Berberidaceae, barberry; Cupuliferae, beech,. birch, 
oak; Oleaceae, ash, fringe tree; Tvlaceae, linden; Salicaceae. 
poplar, willow; Sapindaceae, maple, horsechestnut; Cornaceae, 
sour gum; Juglandaceae, hickory, walnut; Saaxifragaceae, cur- 
rant; Caprifoliaceae, diervilla, honeysuckle; Urticaceae, elm; 
Leguminosae, pea, locust; Mlagnoliaceae, magnolia; Vataceae, 
woodbine. | 
During the past season the caterpillars have been especially 
destructive to sugar maples. Next to the maples they seemed to 
prefer basswood and elm, but in some localities were especially 
destructive to poplar and oak. At Little Falls, N. Y., the writer 
observed them feeding upon ironwood (Ostryia), family Cupuli- 
ferae, making a food-plant additional to the above list.
