July 17. 
Oswego county (C. D. Cook, Oswego Center)—Appletree tent- 
eaterpillars [Clisiocampa americana], bud moths 
[Tmetocera ocellana] and cigar case-bearers [Coleo- 
phora fletcherella] appeared about the time the buds 
began to develop, the two former being abundant, the tent-cater- 
pillars being exceedingly so. No forest tent-caterpillars 
[Clisiocampa disstria] have been observed thus far. 
Plant lice [Aphis mali] are abundant on appletrees, and 
many cigar case-bearers can be found. May 20. Currant worms 
[Pteronus ribesii] and cutworms are numerous and 
causing considerable injury. Plant lice are very abundant on 
plum, pear and apple trees. Tent-caterpillars have not caused 
much injury to the trees. The cold, wet weather has retarded 
the development of insect life. June 5. Hessian fly [Ceci- 
domyia destructor] has caused considerable damage in 
this vicinity. June 19. The forest tent-caterpillar has been 
very destructive in Yates county, the woods about Penn Yan 
being brown and bare in places from their work. The appletree 
tent-caterpillar has also been quite injurious about Penn Yan. 
July 8. 
Otsego county (L. I. Holdredge, Oneonta)—Willow and cabbage 
butterflies [Euvanessa antiopa and Pieris rapae] 
have made an early appearance this season, and the currant 
plant louse [Myzus ribis] is present in great numbers. 
May 6. 
Queens county (C. L. Allen, Floral Park)—Cabbage butterflies 
[Pieris rapae] appeared in large numbers about May 10. 
The rains have destroyed nearly all of them, however. Potato 
beetles [Doryphora 10-lineata| are less numerous than 
usual. June 21. The destructive peaaphis[Nectarophora 
pisi] appeared about June 18, and thus far it has done but lit- 
tle damage. At the present time there are few or none to be 
seen, the severe rains having apparently destroyed them. July
