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. Canker 

 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 [N otolophus 

 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 [Cecidomyia 

 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.
