simonovi, reared from the bollworm (Chloridea obsoleta [HeUothis armigera]) ; 

 and Chelomis caradrinw and Microplites rufiventris, reared from larvae of Cara- 

 drina exigua, all from Tashkend, as new to science. 



Injury caused by Janus luteipes in osiers, W. Baer (Naturic. Ztschr. Forst 

 u. Landic, 12 (1914), No. 6, pp. 292-29.'j; ahs. in Rev. AppL Ent., 2 (191^), 

 Ser. A, A'o. 11, pp. 6//2. 643). — This sawfly is a source of considerable injury to 

 osiers in the Tharandt district through boring in the stems. 



The yellow gooseberry sawfly, L. Fulmek {Reprint from Obstsiichter, No. 

 6 {1914), PP- 4, fiffs. 2; abs. in Rev. Appl. Ent., 2 {1914), Ser. A, No. 10, p. 590).— 

 An account of rteronus ribesii and means for its control. 



An imported red spider attacking fruit trees, L,. Caesar {Canad. Ent., 

 47 {1915), No. 2, pp. 57, 5S, figs. 2). — Tetranychus pilosvs, a European species 

 that attacks fruit trees and is closely related to and perhaps identical with 

 T. mytilaspidis which feeds chiefly on oranges, has been found to occur com- 

 monly on fruit trees in Ontario. The foliage of badly infested trees becomes 

 covered with numerous fine whitish blotches very noticeable on the upper sur- 

 face and after a time turns brown. 



Four new tetranychids, E. A. McGregor {Ann. Ent. Soc. Amer., 7 {1914). 

 No. 4, pp. 354-364, figs. 27). — Four phytophagous mites from the southeastern 

 United States, said to be of considerable economic importance, are described as 

 Temiipalpus bioculatus from privet, strawberry, and other plants at Batesburg, 

 S. C, and Baton Rouge, I^a. ; Tetranychus yothersi from camphor and eucalypts 

 at Orlando, Fla., and elm, oak, and pecans at Batesburg, S. C, etc. ; T. banJcsi 

 from castor beans and velvet beans at Orlando,- Fla. ; and T. quinquenychus 

 from castor beans at Orlando, Fla. 



The beaver fluke (Amphistomum subtriquetrum), Dorothy Duff (Proc. 

 and Trans. Roy. Soc. Canada, S. ser., 8 '{1914), Sect. IV, pp.. S7-98, pis. ^/).— A 

 report of an anatomical and histological study of this fluke. A list of refer- 

 ences to the literature cited is appended. 



Leeches: Exotic leeches, A. E. Shipley {Brit. Med. Jour., No. 2814 {1914), 

 pp. 962-964, figs. 6). — A brief account of leeches of importance. 



FOODS— HUMAN NUTRITION. 



Milling and baking qualities of Victorian wheats, A. E. V. Richardson, 

 P. R. Scott, and F. G. B. Winslow {Jour. Dept. Agr. Victoria, 12 {1914), No. 

 11, pp. 668-675). — In continuation of previous work (E. S. R., 32, p. 659), the 

 authors report a study of the milling and baking qualities of wheat grown under 

 different soil and climatic conditions. 



Regardless of the conditions under which they were cultivated, the same 

 varieties showed the same relative differences in the quality of the grain. In 

 chemical composition it Is thought that seasonal conditions and soil are impor- 

 tant in determining quality. The varieties of highest milling quality were the 

 least prolific growers, and vice versa. 



The gluten content of flours, M. H. Hitier {Bui. Soc. Eneour. Indus. Nat. 

 [Paris], 121 {1914), No. 1, pp. 76-87). — A summary and digest of data which 

 considers the variation, during different years and in different countries, of the 

 gluten content of flours. The variety of seed, kind of soil, and cultivation, and. 

 most important of all, the influence of climatic conditions, are the factors at- 

 tributed by the author to the steadily decreasing gluten content in French 

 wheats especially noticeable during recent years. 



Bread, K. Scheringa {Chem. WcekU., 11 {1914), No. 51, p. i07//).— Chemical 

 examinations of bread are reported which indicate that the fiber content depends
