Wyoming and Genesee counties, as shown by a recent trip ; in some 

 places the trees are entirely denuded. Cankerworms are very abundant, 

 and, unless the trees are sprayed, many of them will be denuded of foli- 

 age. May 31. 



Yates county (Cyrus R. Crosby, Penn Yan) — Appletrees are badly in- 

 fested by aphids [Aphis m al i], there being 20 to 30 lice on each bud. 

 About 1 0% of the buds are infested with bud moth larvae [Tmetocera 

 o cell an a]. Mourning cloak butterflies [Euvanessa antiopa] 

 are more abundant than usual. May 4. The grapevine flea beetle 

 [Haltica chalybea] is doing very little damage. One vineyard 

 of three acres which was badly affected two years ago, and in which 

 they were very numerous last spring is entirely free now. The beetles 

 were thoroughly picked last spring, and the leaves sprayed with paris 

 green. May 11. The cold does not seem to have affected the appletree 

 tent-caterpillars [Clisiocampa americana]. I have seen but 

 one bunch of forest tent-caterpillars [Clisiocampa disstria]. 

 May 12. Appletree tent-caterpillars are as abundant on the apple, peach 

 and plum, as last year, but the forest tent-caterpillars appear to be far 

 less numerous. May 18. Tent-caterpillars [probably both species] are 

 doing damage everywhere. May 25. Tent-caterpillars are doing great 

 damage to appletrees around Penn Yan, and some maples are as bare as 

 in winter. June 2. I find a species of [X y 1 i n a] to be quite common 

 on apricots as well as the plum curculio [Conotrachelus nenu- 

 phar]. June 9. Cankerworms are said to be doing considerable dam- 

 age in the northern part of the county. I found several larvae [A 1 y p i a 

 octomaculata] on grapes. June 15. I have found trouble in 

 keeping the vinegar fly [Drosophila ampelophila] out of 

 cheese case. July 2. The wheat in a great many fields is from one 

 fourth to one half down as the result of the work of the Hessian fly, 

 Cecidomyia destructor. July 13. Late peas are full of bugs 

 [Bruchus p i s i]. July 20.
