 be injurious to roses are classified according to their systematic position, and dis- 

 cussed imder the orders to which they belong, including Coleoptera, Ilymenoptera, 

 Lepido])tera, Diptera, Neuroptera, Orthoptera, and Hemiptera. The author alsodis- 

 cusses the injurious effects of red spiders anil nematode worms. The volume is pro-

Antheraea cytlierea on Pinus insignis at Fort Cunynghame plantation, 

 J. Sims ( Ai/r. Jour. Cape (load Jlopf, :;2 ( /.W.?), IS^o. 4, pp. 440-404, ph. S). — The cater- 

 pillars of this insect are reported as having defoliated Pinus iusUjrds io a large extent 

 and to cause some doubts as to the feasibility of successfully growing this tree in 

 plantations. The depredations caused by the insects are becoming less pronounced 

 from year to year, and the author believe.^ that the tree can be cultivated despite the 

 attacks of thecater[)illars. Notes are given on the habits and life history of this insect. 

 It is parasiti-sed in the egg and caterpillar stages, and is also affected by abacterial 

 disease. No Inrds or mammals were observed feeding upon it. 



The net-winged midges (Blepharoceridaej of North America, V. L. Kel- 

 Locc; {Contrlh. HioL, ILipJdnx Sea.vdr Lnh., J^ehtiid Stanford .Jr. Cnir., 1903, No. 30, 

 pp. 1S3-232, ph. ,'i,fig. 1). — Notes on the anatomy, habits, and life history of species 

 of this family, a number of species l)eing descril)ed as new. 



Intraradical nutrition of diseased trees for the purpose of curing them 

 and destroying parasites, I. Shevuikev {Sehk. Khoz. i Lyesov., JO'.) (1903), Apr., 

 pp. .58-103, Jig.^. .)).— The author describes a number of experiments in which vari- 

 ous substances were introduced directly into the trunks and roots of trees, especially 

 birch and api)le trees, for the purpose of testing the al)sorptive power of these trees 

 and the effect of the substance upon injurious insects. A list of substances thus 

 used included potassium silicate, copper sulphate, various solutions of eosin, fuchsin, 

 carmin, etc. These substances were introduce<l into the tree in ojienings produt-ed 

 by means of an auger. As a result of these experiments the author Ijelieves that a 

 means has been found of benefiting the tree by nutrient solutions at tlie same time 

 that insects are prevented from committing depredations upon the treated trees. A 

 brief bibliography of this subject is presented. 



The [Alabama] horticultural laAW. Notes on some of the insecta and fun- 

 gus diseases affecting horticultural crops, R. S. Mackintosh {Alabama Sta. 

 Bid. 1J4, pp. 73-104, fiy!^. 8). — A copy is given of the recent act passed by the Ala- 

 bama legislature providing means for the protection of horticulture, fruit growing, 

 and truck gardening. The horticulturist of the station is made State horticulturist 

 in charge of the enforcement of this act. The jiests specified in the act as dangerous 

 are San Jose scale, new peach scale, black knot, crf>wn gall, peach yellows, peach 

 and plum rosette, and woolly aphis. Notes are given on the ai)i)earance, habits, and 

 means of combating these pests and formulas are suggested for the preparation of 

 suitable fungicides and insecticides. 



Report of the inspector of fumigation appliances, 1902, P. \V. Hodgetts 

 [Turonta: Ontario Dept. Agr., 1903, pp. 15, Jigs. 2).- — The condition of districts 

 infested with San Jos^ scale is said to be quite serious. Brief notes are given on 

 spring and fall inspection for this insect and on the results of experiments to deter- 

 mine the influence of hydrocyanic-acid gas on plants. Extensive tests with this 

 insecticide showed that plants of all species bear treatment without harm. 



Crude oil and soap, a ne-w general insecticide, II. Maxwell-Lefkov ( Wrst 

 Indian Bui, 3 (1903), JVo. 4, pp. 319-326).— .Kttenium is called to the desirability of 

 using crude oil in the place of kerosene wherever jjossible on account of the mudi
