Canker-worms in Ohio, A. F. BuRtiEss {Ohio Dejd. Ayr., J)lv. Xur.senj and Ordiard 

 Iiixpi'clioii Bill. J, pj). l,i,Ji[/s. 7). — Notes are given on tlie liabits, life history, and 

 distribution in Ohio of tlie fall and spring cankerwornis. Attention is called to the 

 intlnence of unfavorable weather conditions upon the prevalence and distribution of 

 the insect, and brief notes are given on the natural enemies of the cankerw^orm and 

 on aitilicial remedies, such as ])anding the trees and spraying with arsenicals. 



Insects injurious to the apple, (J. PI. Fkencii {Trans. Ill'niois Hart. Soc, ii. ser., 

 S7 {190o),pp. 5.W-5:i5). — The author discusses briefly the habits, life history, and 

 means of combating codling moth, fiat-headed ai)iile-tree borer, and scale insects. 



The curculio and the apple, C. B. Ckandall {Trans. Illinois ILM. Soc, n. ser., 

 37 {I'JOo), pp. 17>!-1S0). — The injuries of the plum curculio, apple curculio, and iilmn 

 gouger are briefly described. Spraying experiments were made, during which 

 aj)i)lications of standard Bordeaux mixture and Paris green were given to apjile 

 trees at 3 periods, viz, when the ]juds were bursting, just after the petals had fallen, 

 and 1 week later. The results indicated that thfe injury from the plum and apple 

 curculios is considerably reduced by this treatment. Notes are also given on the 

 hal»its and life history of these insects. 



The ribbed cocoon maker of the apple, ]\I. V. Slingekl.\xd and Philena B. 

 Fletciiek {New York Cornell >Stu. Bui. :214, pp. 69-78, pis. 4, .fiff-"^- S). — This is a new 

 name proposed Ijy the authors in place of the one which has hitherto been in use, 

 viz, apple bucculatrix. The pest is apparently increasing in number in New York 

 orchards. Descriptive notes are given on the cocoons, caterpillars, and adult insects. 

 The moths of the first brood emerge about the middle of May. They seldom fly 

 except when disturbed. The number of eggs deposited by each female is 4 or 5, and 

 they hatch within from 6 to 10 days. A gradual migration of caterpillars takes place 

 from the upper to the lower branches. In the southern part of New York there are 

 2 broods per year. The ajiple appears to be the preferred food plant. Pear, plum, 

 peach, and cherry trees seem to be immune. A numl>er of parasitic insects are 

 mentioned as assisting in the control of this pest, which is also attacked by birds and 

 spiders. There is a large mortality of the pupa? during the winter. In experiments 

 with remedies it was found that the pupa? of this jjest could be killed by spraying 

 with whale-oil soap at the rate of 1 lb. per gallon of water. Good results were also 

 obtained by tlie use of lime-sulphur-salt and mechanical mixtures of kerosene and 

 water. 



The peach-tree borer, F. Sherman, Jr. {North Carolina Dept. Agr., Ent. Circ. 7, 

 jyp. 5, Jig. 1). — Brief notes are given on the habits and life history of this insect, 

 together with recommendations concerning the most promising methods of com- 

 bating it. 



The Coccidse of Ceylon, III, E. E. Green {London: Dulau d: Co., J 904, pp. 171- 

 249, ]>ls. S3). — In this part of the author's monograph of the Coccidfe of Ceylon the 

 subfamily Lecaniime is considered. A synopsis is given of tlie various genera 

 belonging to this subfamily, and detailed descriptive notes are presented on 33 

 species of Lecanium. 



Treatment of the San Jose scale in cities, A. F. Bukgess {Ohio DejJt. Agr., 

 Div. Nursery and Orchard Inspection Bid. 1, pp. 8, pi. 1, fig. 1) . — Brief descriptive 

 notes on the San Jose scale, together with an account of its life history, distribution 

 in Ohio, natural enemies, and food plants. Formulas are presented for preparing 

 the insecticides most commonly used in destroying this pest. 



A new method of destroying the woolly aphis, E. Andre {Rev. Hort. ^Paris'], 

 76 {1904), No. 4, jjp. S3, 84).— In an orchard infested with the woolly aphis it was 

 noticed tliat trees in close proximity to walnut trees were comparatively immune.
