778 NEW YORK STATH MUSEUM 
(H. D. Lewis, Annandale)—The egg masses of both the forest 
and appletree tent-caterpillars [Clisiocampa ameri- 
cana, ©. disstria] are very numerous, and the indications. 
are that these pests will be very destructive. Appletree bark 
lice [Mytilaspis pomorum] and scurfy bark lice 
[Chionaspis furfura] are very abundant in this sec- 
tion. Ap. 13. Tent-caterpillars appeared in large quantities. 
from Ap. 25 to May 1, and the forest tent-caterpillars were very 
numerous about a week later. Both species will be fully as: 
abundant as last year, though the cool wet weather has held 
them somewhat in check. May18. Forest tent-caterpillars are 
more abundant than ever before. Some orchard and shade 
trees are being completely defoliated by them. The common — 
appletree tent-caterpillar, though numerous. does not appear to 
be so abundant as last year. The rains have been so frequent 
that it has been very difficult to keep insecticides on the trees, 
and consequently these pests are not controlled even by the most 
careful growers. May 24. There are large numbers of tent- 
caterpillars of both species. Cutworms are very numerous, and 
there are some plant lice of different species. The continuous 
rains have made it very difficult to keep the immense numbers 
of forest tent-caterpillars under control. June 1. Potato 
beetles [Doryphora 10-lineata] are just appearing in 
considerable numbers. Tent-caterpillars are beginning to spin 
their cocoons, after having caused more injury than ever before. 
I have noticed robins picking open the cocoons and devouring | 
their contents. Striped squash beetles [Diabrotica vit- 
tata] are quite abundant. Injury by the plum curculio 
[Conotrachelus nenuphar] is apparently much less 
than for many years. June 17. Fall webworms [Hy phan- 
tria cunea] are just making their appearance. Potato 
beetles are more abundant than they have been for years. 
June 29. Trees that were defoliated by tent-caterpillars have 
developed new foliage. Many of the cocoons of the forest tent- 
caterpillar appear dead and shriveled, but no moths have been 
seen in this vicinity. July 19. Red-humped appletreé worms
