c e r a s i] was very abundant at one time this season, but a lady bug and 

 its larva and other beneficial insects soon reduced it to comparatively 

 harmless numbers. The Hessian fly [Cecidomyia destructor] 

 has done considerable damage to some pieces of wheat in this section. 

 The currant worm [Pteronus ribesii] was not as abundant as in 

 previous years. July 7. 



Steuben county (E. P. St John, Prattsburg)— The webs of the 

 appletree tent-caterpillar, Clisiocampa americana, are very 

 abundant on wild cherry. The first web was noticed May 2. Some- 

 times one tree contains a dozen webs. May 7. The recent cold weather 

 has apparently not harmed the tent-caterpillars. The caterpillars have 

 not been very numerous on my farm since I sprayed my trees last year 

 just after they blossomed, with paris green and bordeaux mixture and 

 supplemented that by burning the nests. This year I found the eggs 

 most abundant in one corner of my orchard near some wild cherrytrees, 

 on which the insects evidently bred. May 15. 



Tompkins county (C. E. Chapman, Peruville) — Appletree tent-cater- 

 pillars [Clisiocampa americana] began hatching Ap. 22; only 

 about two thirds of the eggs hatched. Green aphids [Aphis mali| 

 are abundant on appletrees. May i. The cold weather has held the 

 tent-caterpillars in check but otherwise it does not seem to have harmed 

 them. May 15. Potato beetles [Doryphora lo-lineata] are 

 numerous on early planted potatoes. Ap|)letree tent-caterpillars are now 

 well grown. Plant lice are thick on young plumtrees and also on straw- 

 berry plants. June 5. The grubs of May beetles are feeding on young 

 blackberry shoots. June 12. Forest tent-caterpillars [Clisiocampa 

 d i sst r i a] are everywhere but not in sufficient numbers to cause much 

 damage. The 12-spotted Diabrotica [D i a b r o t ic a 12-punctata] 

 is attacking sugar beets in small numbers. Potato beetles are not thick 

 and no eggs have hatched yet. June 26. Striped cucumber beetles 

 [Diabrotica vittata] are abundant, and the same is now true of 

 potato beetles. Some forests show the effects of the forest tent-caterpil- 

 lars, and some bee-keepers complain of the lack of basswood blossoms, 

 which have been cut off by the caterpillars. July 9. Hessian fly 

 [Cecidomyia destructor] is bad in unharvested fields of wheat.

Ulster county {('. ^. Clarke, Milton) — Appletree tent-caterpillars 

 ^Clisiocampa americana] are much more numerous than they 

 were last year. They threaten to do considerable damage. The bud
