lii^tory and econoinic iiu])(jrtancc. Tlu' instx't docs the greatest injury to strawber- 

 ries in late summer and early fall and has been reported from New York State. 

 Infested strawV)erry })iants should not be introduced into uninfested regions and 

 jilants for jiropagation should be grown in nurseries isolated from the fruiting beds. 

 Old infested fields should be plowed under as soon as the fruit is harvested. When 

 the insect becomes so abundant in fields as to re(iuire treatment spraying with kero- 

 sene emulsion or whale-oil soap will give good results. 



Beneficial parasites, W. B. Wall {Jonr. Dept. Agr. West A antra lia, 7 {1903), 

 Xo. 1, pp. 45, 46). — Short notes on the beneficial effects of ladybirds and other pre- 

 dacious parasitic insects which liave been reared and distril>uted for the purpose of 

 assisting in the control of injurious insects. 



Tho Phasmidse, or walkingsticks, of the United States, A. N. Caudell 

 {Proc. U. >S'. Nat. Mm., 2G {1903), pp. 863-885, ph. 4). — Notes are given on the anatomy 

 of this family of insects and an analytical table is presented to assist in the identifi- 

 cation of species belonging to the family. A brief account is presented of the habits 

 and life history of the various species. 



Contribution to a knowledge of the Coleopterous fauna of the Lower Rio 

 Grande "Valley in Texas and Tamaulipas, C. H. T. Townsend {Trans. Texas 

 Acad. Sri, 5 {1903), pp. 51-101). — Notes on the habits, life history, and geographical 

 distril)ution of a number of beetles which occur in this region, 552 species being 

 listed in the article. 



Contribvition to a monograph of the insects of the order Thysanoptera 

 inhabiting North America, W. E. Hixds {Pruc. U. S. Xnt. Mus., 26 {1903), pp. 

 79-242, }th. 11). — The author's investigations on the classification, biology, and 

 means of combating injurious members of this order of insects are systematized in 

 this paper in a monographic form. Notes are given on the history of investigations 

 relating to this order; systematic position of the order; methods of collecting, pre- 

 serving, and mounting; external anatomy; development; and on beneficial and inju- 

 rious species. Various species of thrips are found on flowering jilants, grasses, and 

 other cultivated plants. 



These pests are subject to the attacks of a number of parasites, both of an insect 

 and fungus nature, and to the injurious effects of unfavorable climatic conditions. 

 They may be combated directly l)y means of whale-oil soap or other contact insecti- 

 cides and by cultural methods. A bibliography of 480 titles relating to this order 

 of insects is appended to the article. 



Grasshopper destruction and, white ants, H. Tryon [Queensland Agr. Jour., 

 13 {1903), No. 3, pp. 282-285). — Notes on the prevalence, life history, and means of 

 combating grasshoppers and white ants. The methods recommended for grasshop- 

 pers include various mechanical devices, the use of poison baits, and spraying with 

 arsenical preparations and contact insecticides. Where the white ant colonies are 

 accessible it is possible to dig them up and destroy the ants, or to apply water or 

 contact insecticides. 



The destruction of white ants, A. Loir {Compt. Rend. Acad. Sci. Pctrls, 136 

 {1903), No. 21, jip. 1290, 1291). — Various remedies were tested in the destruction of 

 these insects. The best results were obtained from the use of sulphur fumes, which 

 were drawn through the galleries of the white ants by suction; after introducing a 

 tube into either end of the gallery.

 No. 8, pp. 726-730, pi. 1, figs. 7). — A popular account of the habits and life history of 

 Termes lacteus. 



Flies, E. L. Moore [South Dakota Sla. Hid. 8/, pp. 41, .;/).— A mixture containing 

 fish oil, oil of tar, and crude carlwlic acid is recommended for ridding animals of flies. 

 This mixture was prepared at a co.st of about 35 cts. per gallon and was applied by 

 means of a hand spray pump. One application was found to be effective for 2 days. 

 The milk was not tainted by the odors of the insecticide.
