Seneca county (J. F. Hunt, Kendaia) 
Appletree tent-caterpillar 
[Clisiocampa americana] eggs hatched Ap. 26, and 
those of the forest tent-caterpillar [Clisiocampa dis- 
Stria| May 3s. Canker worms [?Paleacrita vernata| 
commenced work on appletrees about May 1. May 7. Cherry 
aphids [Myzus cerasi] have just begun to appear. Both 
appletree and forest tent-caterpillars are less abundant than 
last year. There are not so many nests of the former species 
to be seen. The steely blue grapevine beetle [Haltica 
chalybea] has not been seen this spring in localities where 
it was abundant last year. May 1%. Currant worms 
[Pteronus ribesii] appeared May 20, and work of the 
plum curculio [Conotrachelus nenuphar]| is now 
evident, but this pest is not so injurious as in former years. 
The forest tent-caterpillar in particular is not so abundant 
as it has been in recent years. Bud moths [Tmetocera 
ocellana] are more numerous than for years. Currant 
worms and raspberry sawflies [Monophadnoides rubi|] 
are both scarce. The fruit tree bark beetle [Scolytus 
rugulosus] is working quite abundantly in plum and peach- | 
trees, but not so badly, however, in the latter. The orchard 
which the canker worms defoliated last year and in which 
they appeared this year is now all right, the pests having been 
controlled by two sprayings. May 29. The work of the Hes- 
sian fly [Cecidomyia destructor] is now in evidence, 
it having destroyed about one third of some species of wheat, 
and there are but few curculio marks on apricots and plums. 
Tent-caterpillars are showing up a littie more abundantly than 
was reported last week. There are no potato beetles 
Mierwpeora L0-lineata] to speak of yet.. The last 
week of rain has apparently had no bad effect on the cater- 
pillars. June 7. Eggs of the potato beetle are beginning to 
hatch, and the parent insects are very plentiful. Tent-cater- 
pillars are now leaving the trees and spinning cocoons. The 
Hessian fly is very destructive in some pieces of wheat, while 
in others not much is seen of it. Zebra caterpillars [Mam-
