have gone, Mr. Koebele contiruis results obtained by the Division^ in 

 the IsTew York hop fields in 1887. While it is undoubtedly true that 

 other mixtures may be applied more safely to the crop while in the 

 burr, the enlightened hop-grower will never allow his yard to be infested 

 as late in the season as this. Preventive work on neighboring- jilums 

 should come first. Then, if by chance the yard becomes stocked from 

 plum trees at a distance, all insecticide work should be done about the 

 time of the disappearance of the migrating generation. Thorough work 

 at this time will obviate the necessity for any farther labor. 



The insect portion of this bulletin is followed by some account of 

 gophers and moles, with the remedies to be used against them. The 

 remedies mentioned are exclusively in the line of traps and poisoned 

 food, the excellent bisulphide of carbon treatment, which has been 

 recommended for some years by the Division of Economic Ornithology 

 and Mammalogy of this Department, and which forms the subject of a 

 recent bulletin by Mr. ISTiswander of the Wyoming Station, being 

 ignored. 



Insects Injurious to Crops in England in 1892. — Our friend and corre- 

 spondent, Mr. Charles Whitehead, in his capacity of technical adviser 

 to the intelligence branch of the Board of Agriculture of Great Britain, 

 has just pul)lishcd an interesting and well-illustrated report upon the 

 insects and fungi injurious to crops in 1892 in that country. Most of 

 the species treated are distinctively European, but American readers 

 will be interested in what he has to say about the Grain Aphis [Sipho- 

 nophora granaria), the Turnip Aphis {Apliift hnissica'), and the Cab- 

 bage Fly [Anthomyia hrassiea>), as well as the Eed Spider [Tetranycliufi 

 tdarii(.s), although little or nothing new is brought out. The colored 

 plates accompanying the leport are esj)ecially good, that illustrating 

 the Apple-blossom Weevil {Antho)iomiiH pomorum) being particularly 

 interesting to us at the present time on account of the striking simi- 

 larity between the work of this insect and the work of our Strawberry 

 Weevil {Anthonomns sujiuituH). 



The Bud Moth.— Mr. Sliugerland has given us, in Bulletin 50* of the 

 Cornell Station, an admirable summary of the facts concerning Tmeto- 

 cera oceUaiM, a well-known orchard pest of the northeastern States. 

 He deals with its past history and classification, the indications of its 

 presence, its general appearance, its life-history, its natural enemies, 

 and the best methods of preventing its ravages. He shows from exper- 

 iiiient that Paris green spray applied at the time the buds are begin-
