ENTOMOLOGY. 273 



remedy. A somewhat lengthy note on the pernicious scale, which has appeared in 

 the Province, besides mentioning something of the marvelous reproductive powers of 

 this insect in the United States ; notes on 3 classes of remedies applied to it, namely, 

 corrosive washes, such as whale-oil soap, penetrating substances, such as kerosene 

 emulsion and gases, and varnishes, such as resin washes. There are also given 

 brief instructions as to spraying mixtures, note being made of Bordeaux mixture, 

 amnioniacal copper sulphate, Paris green, 1 lb. to 200 to 300 gal., hellebore, pyreth- 

 rum, and kerosene emulsion. 



Entomology, W D. Hunter (Nebraska Sta. Rpt. 1897, pp. 27-30).— -The author 

 briefly notes experiments with Sporotrichum globuliferum, Empum grylli, and a bac- 

 terial disease of grasshoppers, commenting more or less favorably upon the effects 

 of the first two and on insecticides. The latter were with carbon bisulphid, con- 

 cerning which it is thought that the different conditions under which it may be 

 effectively employed are not well known, and the experiments were undertaken to 

 learn new methods of applying it, whereby the expense attending its use might be 

 lessened. The substance was used against plant lice inhabiting cucurbitous plants, 

 borers in peach trees, larva? of May beetles in nurseries and young orchards, and 

 some species, such as Sitodrepa panicea, which damage stored dry animal and vege-. 

 table matter. 



Insect notes of the season, W. E. Britton (Connecticut State Sta. Ept. 1897, pp. 

 314-319). — Descriptive and life history notes are given on the following insects, with 

 an account of their injuries during the season and suggestions as to remedies: 

 Apple curculio (Anthonomus quadrigibbus) on peach twigs; San Jose scale; "virgin" 

 or "white ermine" moth (Spilosoma virginica) on hollyhocks; grapevine flea-beetle 

 (Haltica (Graptodera) chaltjbea); a plant louse (Pemphigus acerifolii) on maples; a 

 lily-stalk borer, closely resembling Gortyna nitela, and presumably that species; 

 saw-tooth grain beetle (Silvanus surinamensis) ; meal snout moth (Pyralis farinulis), 

 and plant lice. A technical description is given of the lily-stalk borer. The gypsy 

 moth (Ocneria dispar) was reported from Hartford, but as all the specimens were 

 destroyed the scientific accuracy of the report could not be determined. The 

 author is inclined to believe, however, that the larvae belonged to some of the more 

 common species and not to the moth imported from Europe. 



Some new spiders, N. Banks (Canad. Ent., 30 (1898), No. 7, pp. 185-188).— Pceci- 

 lochroa minuta from Brazos County, Texas; Cybaodes (?) incerta from Salton, Cali- 

 fornia; Theridium subterraneum from Washington, D. C. ; Nasticus cavicola from 

 Chiricahua Mountains, Arizona; Erigone albescens from Washington, D. C; and 

 Philodromus pacificus from Olympia, Washington. 



The contests against grasshoppers in the delta of the Danube, E. Rekalo 

 (Selsk. Khoz. i Lyesov., 187 (1897), Oct., pp. 99-126).— Since the chief brooding ground 

 of the grasshoppers devastating Bessarabia is at the delta of the Danube, the author 

 recommends joint action of Russia and Rouinania in combating the iusects at the 

 delta. — P. FIREMAN. 



Insects injurious to Helianthus annuus, A. Krulikovski (Selsk. Khoz. i Lyesov., 

 185 (1897), June, pp. 585-598). 



The San Jose scale (Pennsylvania Dept. Agr. Bui. 34, pp. 45-49). — A popular paper, 

 quoting largely from P. H. Rolf (E. S. R., 9, p. 1068), from J. P. Smith and F. M. 

 Webster. 



Bordeaux mixture as an insecticide, J. H. Panton (Ontario Agr. Col. and Expt. 

 Farm Rpt. 1897, p. 24).— Experiments were made with Bordeaux mixture on goose- 

 berry bushes to test its efficacy as an insecticide. Three applications were gisen 

 the bushes. Further experiments were conducted in spraying tent caterpillars with 

 Bordeaux mixture and Bordeaux mixture with Paris green. The Bordeaux mixture 

 seemed to have some effect as an insecticide, but the author believes that applica- 

 tions of limewater gave results similar to those of Bordeaux mixture. The addi- 

 tion of Paris green increased the efficiency of the mixture.
