 2. ncr., 190.}, No. 17, pp. /f.i-124, ph. 7). — A detailed description of the more impor- 

 tant anatomical features, habits, and life history of various species of this group.

 1903, ])j>. ,s'.7, //ry.s'. .)0). — A discussion is presented on the anatomical details, feeding 

 lial)its, life history, parasites, and construction of the nests of ]^e.tp(i. erahro, 1'. media,

Biolog-y of the genus Chermes with special reference to C. piceae, O. Ntjss- 

 LiN ( VcrJiandl. Xaturn: Vcr. Karlsralte, 10 {1 90 2-3) , pp. 3-20). — As a result of the 

 study i)f Chermes picex and other species of this genus the author conies to the con- 

 clusion that C. piceir. is reprodu(;ed parthenogenically and that the disadvantages of 

 this form of reproduction are partly overcome by the existence of a long-lived larval 

 form. 



How^ to combat the Mexican cotton-boll w^eevil in summer and fall, E. D. 

 Sandeksox {Te.vas Sta. Circ. 4, PP- 4)- — The remedies fur this insect, as mentioned 

 by the author, consist in growing an early maturing cotton, and in destroying the 

 beetles by grazing the cotton with cattle and pulling and burning stalks which are 

 unused. It is also recommended that the land be plowed deeplj' in late fall or early 

 winter. 



Insects attacking cotton in the West Indies, H. A. Ballou ( }Yest Indian Bui., 

 4 {1903), Xn. 3, pp. 268-286, Jigx. 4). — Economic and biological notes are presented 

 on cotton worm, bollworm, Mexican cotton-boll weevil, cotton-plant louse, scale 

 insects, cutworms, grasshoppers, D>jsdercus undrew, D. annulliger, species of Phytop- 

 tus, etc. 



Some insects attacking the stems of growing wheat, rye, barley, and 

 oats, w^ith methods of prevention and suppression, F. M. Webster ( JJ. S. Dept. 

 Agr., Division of Entomology Bed. 42, pp. 62, figs. 15). — The chief purpose of this 

 bulletin is to present descriptions and notes on the habits and life history of a num- 

 ber of small insects of cereal crops. The injury due to these insects has frequently 

 been mistaken for the attacks of the Hessian fly. The species specially considered 

 in the bulletin are Isosoma grande, I. tritici, I. liordei, I. captivum, I. wehsieri, I. hirti- 

 frons, I. secale, I. filchii, Meromyza americana, Oscinis carbonaria, and 0. soror. 



In connection with a discussion of each one of these species various suggestions are 

 made regarding cultural methods which will materially assist in controlling the 

 pests. According to the author's observations it may be stated as a general rule that 

 the same remedies which tend to hold the Hessian fly in check are effective against 

 other small cereal insects. The cultural remedies most confidently recommended 

 include the destruction of grass and other jslants on which these pests may live in 

 the neighborhood of grain fields, rotation of crops, burning of stubble, and late 

 seeding. 



A brief account of the principal insect enemies of the sugar beet, F. H. 

 Chittexdex ( U. S. Dept. Agr., Division of Entomology Bui. 43, pp. 71, figs. 65). — This 

 material has already been abstracted from another source (E. S. R., 15, p. 379). 



Catalogue of the Museum of the Experiment Station for Sugar Cane in 

 West Java, W. Yax Devexter {Froefstat. Sidkerriet West Java, Bui. 6, 1903, pp. 46, 

 pi. 1). — A list is presented of the varieties of sugar cane-in the museum and of the 

 species of insects and other injurious animals and fungus diseases which occur on 

 sugar cane. The different species of insects and fungus pests are briefly described 

 and recommendations are given regarding the best methods for combating them. 



The sugar-cane borer (Chilo simplex), E. P. Stebbing {Indian Mus. Circ. Agr. 

 Econ. Ent., Xo. 3, 2)p. 6, figs. 2). — This insect may be controlled by cutting out and 

 destroying infested canes and burning or burying all discarded tops and refuse after 

 the crop has been cut over.
