weather seems to have kept insect pests in check. May 13. 
Forest tent-caterpillars have not done much damage. They are 
about one third as abundant as last year. Plant lice are quite 
numerous on apple, plum and cherry trees. Currant worms 
[Pteronus ribesii] are quite abundant in this vicinity. 
June 6. Potato beetles [Doryphora 10-lineata] have 
appeared, and plant lice are quite abundant on cherrytrees, 
causing the leaves to shrivel and die. Forest tent-caterpillars 
are spinning their cocoons and have not caused much damage. 
Grasshoppers are present in large numbers. The moths of the 
forest tent-caterpillar appeared July 1 and have commenced to 
deposit eggs. Potato beetles are very abundant. July 11. 
Grasshoppers are very numerous and are injuring corn and buck- 
wheat. Aug. 12. | . 
Schuyler county (Harriet M. Smith, North Hector)—Appletree 
tent-caterpillars [Clisiocampa americana] were first 
seen May 1, canker worms [? Paleacrita vernata]| May 
6. The latter have been very destructive to buds and small 
leaves on plumtrees. The tent-caterpillars are very abundant, 
but have caused but little damage as yet. May 17. Both the 
common and the 12 spotted asparagus beetles [Crioceris 
asparagi and C. 12-punctata] are abundant. Sanker 
worms are defoliating many maple trees. Owing to the de- 
struction of the nests of the appletree tent-caterpillar in 
orchards, this pest has caused but little injury in this vicinity. 
The late storm has apparently killed many insects. June 7. 
White marked tussock moth caterpillars [Notolophus 
leucostigma] have been quite injurious to horse chestnut 
trees. Oats are reported as seriously damaged by a plant louse 
in Seneca county. July 12. I am unable to learn of any wheat 
being seriously injured by the Hessian fly [Cecidom yia 
destructor] in this vicinity, as most of it was sown late. 
June 14. Potato beetles [Doryphora 10-lineata] ap- 
peared for the first time this season about June 15, and they 
are now present in great abundance. June 21. The Hessian 
fly has injured wheat at North Reading. July 19.
