are scarce. Currant worms (Pteronus ribesii Scop.) have 

 commenced operations, and black flea beetles (Crepidodera 

 cucumeris Harr.) are at work on tomatoes. Scarcely any 

 plum curculios (Conotrachelus nenuphar Hrbst.) have 

 been observed. Cold, wet weather seems to have checked the 

 development of insects. Many peartrees have blighted; this is 

 probably due to their inability to withstand the severe winter after 

 being badly injured by pear psylla (Psylla pyricola Forst.) 

 the preceding year. — June i8. Striped cucumber beetles (D i a- 

 brotica vittata Fabr.) appeared in some numbers on squash 

 vines. — June 2j. Other insects have not attracted attention by 

 their abundance. — June 26. Fall webworms (Hyphantria 

 t e X t o r Harr.) have been much more abundant than usual. 

 Cabbage butterflies are not as thick as they were last year. Other 

 insects have not been abundant enough to cause trouble during the 

 past season. — Sep. 8 



Ca3niga county [Purley Mintum, Locke] — A worm, probably a 

 species of cutworm, has been eating cabbage plants off just at the 

 top of the groimd. — July 8. Apparently, insects are remarkably 

 scarce in that section, as no other reports were received. 



Genesee county [J. F, Rose, South Byron] — No complaints of 

 canker worms (Paleacrita vernata Peck) have been 

 received. Tent caterpillars (Malacosoma americana 

 Fabr.) are very scarce. A long ride along highways fringed with 

 wild cherries and bordered by many orchard trees, resulted in 

 the discovery of only three nests. Rosebushes are as usual infested 

 with plant lice. A few currant worms (Pteronus ribesii 

 Scop.) have appeared and the currant stem sawfly Q a n u s 

 integer Nort.) has begun its operations. A farmer reports 

 plowing up potato beetles (Doryphora lo-lineata Say) 

 in lively condition. — May ji. Striped cucumber beetles (D i a - 

 brotica vittata Fabr.) appeared flrst June 9 and became 

 numerous the 12th. The first squash bugs (Anasa tristis 

 DeGeer) were met with June 12. The cabbage stem maggots 

 (Phorbia brassicae Bouch^) are very destructive; they 

 left only one out of 23 early cabbage plants, in spite of the fact 

 that the plants were treated with fine salt. Cankerworms and tent 

 caterpillars are not abundant. Potato bugs are numerous on early 

 potatoes and some egg clusters have been deposited. There are 

 very few plant lice on fruit trees. — June ij. Fall webworms 

 (Hyphantria textor Harr.) were first observed July 2. 

 Plant lice of various kinds continue scarce. We hear no com-
