The Pear-Midge. (Albany Evening Journal, for May 30, 1893, 



p. 6, c. 5 — 8 cm.)

The Invasion of Plant-Lice in New York. (American Farmer, 

 Ixxiv, for June 1, 1893, p. 1, c. 4 — 28 cm.) 



The apple-tree aphis, Aphis malt, is unusually abundant, apparently 

 throughout the State. Importance of reducing it by spraying. The early 

 rains do not seem to have materially diminished it. Anxiety of the hop- 

 growers lest the conditions favorable to aphis multiplication this year 

 should so increase the hop-vine aphis that its injuries of 1886 shall be 

 repeated; they are urged to watch for its first appearnce and at once spray 

 for it. The " hop-washings" in England.

 Iviii, p. 419, c. 2 — 15 cm.) 



Replying to an inquiry from Seneca county, N. Y. : The aphis may occur 

 on the opening buds without blighting the blossoms. Young aphides are 

 destroyed by heavy rainfalls. Their multiplication may seriously impair 

 fruit crops. Young apple trees may be killed by aphis attack. Importance 

 of spraying to prevent injury just after the aphides have hatched.

 Iviii, p. 4 IP, c. 2, 3 — 18 cm.)

 and remedies .

 as operating on field potatoes. J. ccendeocinctus not the cause of the 

 scab.— See Country Gentleman, for April 27, 1893, p. 329. Kainit given as 

 a remedy for the thousand-legged worm . Wire-worms would not be killed

A Greenhouse Pest. (Gardening, for June 15, 1893, i, p. 313, 

 c. 1-3 — 61 cm.) 



Reply made to a communication from Boise, Idaho, of flies injuring

 Mr, R. H. Meade, near to the European S. nervosa. Some of the flies, re- 

 ceived in 1889 from a gentleman in Albany as injuring mushrooms, were 

 sent to Mr. William Falconer. He states that ' ' he had never regarded them 

 as injurious to mushrooms, although there were thousands of them in the
