there appears to be a short crop of injurious insects. Apple tree tent 

 caterpillars [Clisiocampa americana] are not up to the 

 average, and those seen appear to be less active. May 9. A few elm 

 leaf beetles [Galerucella luteola] have made their appearance 

 in the southern part of the township. Insect pests very scarce. May 27. 

 Work of forest tent caterpillars [Clisiocampa disstria] not 

 seen. Aphids are appearing somewhat, specially the black cherry aphis 

 [Myzus cerasi|. Potato beetles [Doryphora 10-lineata] 

 not abundant. June 2. A decided increase in plant lice of all kinds, in 

 spite of the dry weather. One attack by forest tent caterpillars on about 

 10 or 12 trees has been brought to my attention. Potato beetles more 

 numerous. Rose bugs [Macrodactylus subspinosus] very 

 numerous. Currant worms [Pteronus ribesii] abundant. June 16. 

 Apple aphis still increasing in numbers and doing considerable injury to 

 recently set trees and in some cases tc the new growth of mature trees, 

 June 30. A few trees in this section badly affected by elm leaf beetle. 

 The pest is not so bad as two or three years ago but worse than last year. 

 Work of the codling moth [Carpocapsa pomonella] is beginning 

 to show. I am satisfied that if orchards were persistently sprayed and 

 all wormy fruit destroyed this pest would be much reduced. July 29. 



(Ruth Sherwood, Fishkill) — Apple aphis [Aphis m a 1 i] present in 

 numbers. Grapevine flea beetle [Hal tic a c h a 1 y b e a] is doing 

 much injury by eating out the buds. May 20. The foliage of forest and 

 fruit trees shows no injury from insects. Grape vine flea beetles inflicting 

 much injury on young apples. Horse flies [Tabanidae] very 

 annoying to cows. June 10. 



(Franklin A. Taber, Poughkeepsie) — Cold, dry weather has been 

 unfavorable for many insects. A few apple tree tent caterpillars 

 '[Clisiocampa americana] and currant worms [Pteronus 

 ribesii] have appeared. Black flea beetles [E p i t r i x cucumeris] 

 have appeared on early potatoes No Colorado potato beetles [Doryph- 

 ora 1 o-l i n e a t aj in sight, not even an old one. A few aphids on 

 sour cherries. Larvae of grape vine flea beetle [Haltica chalyb- 

 e a] attacking grape leaves, most numerous next to the woods on the 

 north side of the vineyard. May 25. This season has been marked by 

 fewer insect pests than for years. There was a late crop of potato 

 beetles which did little damage. An insect has been working in the 

 stems of potato vines. Aug. 11. 



Erie county (M. F. Adams, Buffalo) — The syringa borer, Podo- 

 sesia syringae, was found three years ago infesting and badly
