 was comparatively little to report from this section. — June 10 



Cattaraugus county [F. A. Fitch, Randolph] — Appletree tent 

 caterpillars (Malacosoma a in er i c a n a Fabr.) appeared 

 the latter part of April and were very abundant in neglected 

 orchards, increasing immensely in numbers during the last two or 

 three years. Squash bugs (Anasa tristis DeGeer) ruined a 

 crop of squashes in this section last year. Cabbage butterflies 

 (Pieris rapae Linn.) appeared about the middle of May, 

 and the same was true of May bugs, species unknown, and various 

 mosquitos. The white grub of the May beetle has not been as 

 destructive as in former years. — May 18. Potato beetles (Dor y- 

 p h o r a 10-1 i n e a t a Say) , grasshoppers and the 'plum curculio 

 (Conotrachelus nenuphar Herbst.) made their appear- 

 ance May 26. Early in June curculios were reported as being at 

 work, potato beetles as laying eggs, and plant lice as being present 

 on cherrytrees. The latter are the ordinary black species 

 (Myzus cerasi Fabr.) which has been unusually destructive 

 and injurious in various sections of the State. Squash bugs ap- 

 peared June 18, horn flies (Haemotobia serrata Rob. 

 Desv.) the second week in June, and rose beetles (Macrodac- 

 tylus subspinosus Fabr.) were very abundant on some 

 rose bushes. Potato beetles are somewhat abundant and are lay- 

 ing eggs on potatoes. So far this season insects appeared to be 

 less injurious than usual, probably on account of cold rains. 

 — June 22. Large, green horseflies are quite troublesome and 

 young grasshoppers are numerous on lowlands. Insect depreda- 

 tions are less than usual. — July 8. There are few mosquitos in 

 the village and on the farm we saw none where commonly there 

 have been millions. Ditching the land has undoubtedly aided 

 very much in reducing their number. Flies are also less abun- 

 dant than usual. — July 22. The first cabbage butterfly w r as ob- 

 served in the field Aug. 11. A single mosquito was observed re- 

 cently, though none had been seen for weeks before. Cabbage 

 maggots (Phorbia brassicae Bouche') are working to 

 some extent on cabbage, and the same is true of the cabbage louse
