Scop.) put in appearance May 18, and the same is true of the 

 appletree aphis (Aphis mali Fabr.) . — May 22. Eggs of the 

 potato beetle (D o r y p h o r a 10 - 1 i n e a t a Say) were observed 

 May 21, and shad flies or May flies, the 22d. Mosquitos were 

 abundant on the 25th. Generally speaking, no insects are spe- 

 cially injurious. — May 28. Cucumber beetles (Diabrotica 

 vittata Fabr.) were very numerous June 4; same was true 

 on the 10th of strawberry weevil (?Anthonomus signatus 

 Say) and potato beetles. White grubs are abundant and totally 

 destroying oats. — June 11. Cabbage worms appeared on the 20th, 

 and onion maggots (Phorbia ceparum Meigen) were at 

 work the 22d. This latter insect has destroyed one fourth of 

 the onion crop. Cabbages have likewise suffered from the maggot 

 (Phorbia brassicae Bouche') . Rose slugs were observed 

 at work on the 23d. — June 25. A second brood »of currant worms 

 appeared July 1. Cabbage worms, cucumber beetles, plant lice 

 and onion maggots are very numerous and destructive. The wet 

 weather continues, accompanied by an increase of leaf-eating 

 insects. The foliage of appletrees, plumtrees, maples and elms 

 are all attacked by plant lice. Some apples are dropping and 

 show no sign of injury except at the end of the stem, probably the 

 work of the codling moth (Carpocap'sa pomonella 

 Schiff.). — July 9. Crane flies and dragon flies were numerous 

 July 10, and a single specimen of the tomato worm (P h 1 eg e - 

 thontius 5 - m a c u 1 a t u s Haw.) was observed on the 15th. 

 Cabbage worms, potato beetles and plant lice continue abundant 

 and destructive. Mosquitos are abundant and rains continue. 

 Striped cucumber beetles and plant lice are attacking vines, egg 

 plants and wild tansy. — July 16. White marked tussock moths 

 (Notolophus leucostigma Abb. & Sm.) were observed 

 July 20, and dragon flies on the 15th. Potato beetles are abund- 

 ant and plant lice very numerous, mosquitos are rare. Cool and 

 wet weather has interfered with the successful application and 

 efficiency of insecticides, and as a consequence caterpillars are 

 abundant. Apples are dropping from the tree, and only about 

 one quarter of the crop will be saved. Most of the trouble is
