658 EXPERIMENT STATION RECORD. 



duced into New York State in June, 1909, on foreign nursery stock. It is said 

 that tliis is tlie first time tbat the pest, wliicli in certain European countries is a 

 very destructive enemy oi' fruit trees, has been introduced into tlie United States. 

 Present knowledge indicates tbat it has not established itself in the State. Fur- 

 ther Observations on Empoasca mali; Notes on Papaiiwina nitcla and P. cata-, 

 phracta (E. S. R., 21, p. 56) were presented by F. L. Washburn (pp. 162-168), 

 and a paper on Work on the Apple Maggot by W. C. O'Kane (pp. 169-172). In 

 a paper on Spraying for the Codling Moth (pp. 172-176), E. P. Felt reported 

 experiments made to test the efficiency of a coarse driving spray as compared 

 with a fine mist spray. He concludes that the results obtained seem, so far as 

 the Hudson River is concerned, to justify the belief that one thorough spraying 

 with a Vermorel nozzle within a week or 10 days after the blossoms fall will 

 result in protecting a very large percentage of the fruit from codling moth 

 injury. Notes on the Ten-Lined Potato Beetle in Montana were presented by 

 R. A. Cooley (pp. 178, 179). The author has found that there is but one brood 

 of the Colorado potato beetle in the Gallatin Valley. Under Insect Notes from 

 Illinois for 1909 (pp. 180-186) J. J. Davis reported upon the occurrence of insects 

 of the truck farm and vegetable garden, and insects injurious to flowering plants, 

 shade trees, and ornamental shrubs. 



Several papers read by title are presented in the report, namely. The 

 Season's Work on Arsenical Poisoning of Fruit Trees, by E. D. Ball, E. G.

 Hertzog (pp. 198-202) ; Studies of the Development of Etipchmis aUynii and 

 Stictonotus isosomatus, by E. O. G. Kelly (pp. 202-204) ; Collembola as Injuri-

 sorghicoUt) (pp. 205-207), by W. H. Dean (E. S, R., 2.3, p. 364) ; Some Insecti-

 Beneficial Insect, by A. F. Burgess (pp. 217-222). 



Proceedings of the eighth annual meeting of horticultural inspectors 

 {Jour. Ecun. Ent., 3 {1910), No. 2, pp. 223-250). — This is a continuation of the 

 report previously noted (E. S. R., 23, p. 360). Three papers were presented, 

 namely. What Should be the Form of our Certificates V by F. Sherman; Some 

 Obscure Diseases of Peach, by J. B. S. Norton; and Local Inspection. Public 

 Sprayers and the Osage Orange Hedge, by T. B. Symons. A general discussion 

 followed. 



The entomological section, D. Gunn and F. Thomsen {Transvaal Agr. Jour., 

 8 {1909), No. 29, pp. 77-94, pis. o). — The injury caused by the granary weevil, 

 rice weevil, and Angoumois grain moth, and remedial measures therefor are 

 considered. An account is then given of the potato tuber moth {Gelechia oper- 

 culella) which is an important pest in the Transvaal. Tests made in continua- 

 tion of investigations previously noted ( E. S. R., 22. p. 357), to determine the 

 value of chemicals and other substances in preventing the injury to wood by 

 termites are reported. The woolly aphis, cottony cushion scale, peach-tree 

 aphis, cockchafers, fruit fly, and the red and green colored grasshopper {Ochro- 

 phcbus carinata) are also considered. 



Entomological notes, B. C. Burt {Rpt. Caicnpore [India], Agr. Sta., 1909, 

 pp. Jfl-45). — Among the species the occurrence of which is noted are the cotton 

 leaf-roller {Si/lcpta deroguta), cabbage aphis, spotted boll-worms {Earias fabia 

 and E insulana), red boll-worm {(Iclcchia gossginelhi), Clavigalla horrcns,
