dry for the last two or three weeks. Cabbage worms [P i e r i s 

 rapae] are very abundant. Aug. 2. Fall webworms are very 

 numerous on maples. Many dead grasshoppers are found in the 

 fields. Sep. 3. 



Livingston county (W. R. Houston, Geneseo) — Appletree tent- 

 caterpillars [Olisiocampa americana] made their ap- 

 pearance Ap. 28 almost before the buds began to swell. They 

 are just as numerous as last year. I understand that some 

 farmers sprayed before the buds opened. The cold weather 

 seems to keep them in check, and, though they wander over the 

 trees, they do not seem 1 to feed much. May 10. May 17 many 

 nests of the appletree tent-caterpillar were seen in cherry and 

 thorn trees beside the road, and there were also many unhatched 

 eggs. May 24. 



Montgomery county (S. H. French, Amsterdam) — The eggs of 

 the European praying mantis [Mantis r e 1 i g i o s a] were re- 

 ceived in good condition and have been distributed as follows: 

 one packet attached to a small rosebush in my back yard; one 

 in the yard of a friend of mine who lives in the suburbs of the 

 city; and the remainder in the cemetery, where there is plenty of 

 small vegetation. Ap. 17. I have discovered no evidence of the 

 presence in this section of the elm leaf beetle [Galerucella 

 luteola] or of the forest tent-caterpillar [CI i si o cam pa 

 -disstria], and I find very few nests of the appletree tent-cater- 

 pillar [Clisiocampa americana]. The latter are not as 

 numerous on cherry or apple trees as usual. May 13. 



Niagara county (R. L. Darrison, Lockport) — A large proportion 

 of the winter wheat is seriously damaged by the Hessian fly 

 [Cecidomyia destructor], and where but a few weeks 

 ago there was every promise of an abundant crop, many fields 

 are ruined, and some farmers are now plowing their wheat under. 

 The egg cases of the praying mantis [M a n t i s r e 1 i g i o s a] 

 were distributed among representative farmers, nurserymen and 

 market gardeners, but as yet none have been reported as 

 hatched. June 13. So far only one of the egg cases of the pray- 

 ing mantis has developed satisfactorily. This was placed in a
