from Pnlvinaria bigclovice at Grand Junction, Colo., and Port Lavaca, Tex. ; 

 C. minor reared from the blackhead fireworm at Whitesbog, N. J., from Gnori- 

 moschcma artemisieUa at Chicago, 111., from Oelechia sp., at Benton Harbor, 

 Mich., from the pecan cigar case-bearer at Victoria, Tex., and from Eucosma 

 strenuana on Ambrosia trifida at Washington, D. C. : platynotce and Platy- 

 nota fiaredana at Tempe, Ariz. ; C. tortricidis and C. epagoges reared from 

 Epagoges sulfureana at Nashville, Tenn. ; C. evetrice from Evetria bushnelli at 

 Fort Bayard, N. Mex. ; C. cleridivorus reared from the larv£e of Enoclerus 

 quarigutiatus at Kanawha Station, W. Va., Tryon, N. C, and Lawrence, Kans. ; 

 C. ros(E from rose hips in company with Rhynchytes bicolor but which were also 

 apparently infested with a lepidopterous larva, at Vienna, Va. ; C. tetralophcB 

 from Tctralopfia subcaruilis at Monticello, Pla. ; and C. mordellisteruB from Mor- 

 dellistena morula in Colorado. 



The author has found that C. decoratus has apparently been introduced into 

 the United States with one of its European hosts, Evetria buoliana, a specimen 

 having been reared from that host on Long Island, N. Y. C. forbesii, originally 

 described from specimens reared from Acleris minuta, is represented in the 

 National Museum by specimens reared from Gelechia trialbamaculella at Pem- 

 berton, N. J., blackhead fireworm at Pemberton, N. J., O. confusella at Benton 

 Harbor, Mich., and Episimus argutanus at East River, Conn. 



Notes and descriptions of miscellaneous chalcid flies (Hymenoptera), A. A. 

 GiBAULT {Proc. U. S. Nat. Mus., 53 (1917), pp. 445-450). — Twelve species rep- 

 resenting ten genera are described as new. Among these are Tumidiscapus 

 oophagus, many specimens of both sexes of which were reared from eggs of 

 Oxya velox, at Coimbatore, Southern India ; Abbella americana reared from 

 jassid eggs in Elymus. at Salt Lake City, Utah; and Sympieses ancylce reared 

 from Ancylis sp. at Whitesboro, N. J. 



The fish louse (Argulus foliaceus), R. Meele (Sci. Amer. Sup., 84 {1911), 

 No. 2189. p. 373, fig. 1). — A brief account of A. foliaceus, w'hich destroys carp, 

 etc., with a discussion of preventive and remedial measures. 



Brazilian cecidia of plants belonging to the families Compositae, Rubia- 

 ceae, Tiliace^, Lythracese, and Artocarpacese, J. S. Tavares {Broteria, Ser. 

 Zool., 15 (1917), No. 3, pp. 113-181, pis. 6, figs. 4).— This contribution to the 

 knowledge of Brazilian cecidia includes descriptions of 4 genera and 11 species 

 new to science. 



FOODS— HUMAN NTJTEITION. 



Chemistry of food and nutrition, H. C. Sherman (New York: The Macmillan 

 Co., 1918, 2. ed., rev. and enl., pp. XIII+454, figs. i6).— This book has been 

 rewritten and enlarged to include the results of the more important investiga- 

 tions in nutrition since the first edition (E. S. R., 24, p. 759). Among these 

 may be mentioned the greatly extended knowledge of the nature and nutritive 

 value of individual proteins and of the chemical changes involved in the inter- 

 mediary metabolism of carbohydrates, fats, and proteins; new data on energy 

 requirements under different conditions; and additional facts concerning inor- 

 ganic constituents, particularly calcium and phosphorus, and the maintenance 

 of neutrality in the body. Perhaps the most interesting and significant of the 

 recent investigations are those which have led to the establishment of new 

 factors essential to the nutritive requirements of the body, the unidentified sub- 

 stances referred to as " vitamins " or as " fat soluble A" and " water soluble B." 

 These are described in the chapters on antiscorbutic and antineuritic properties 

 of food in relation to growth and development. 



The book closes with a chapter on dietary standards and economic use of food 

 in which the problems of an adequate diet are discussed from the viewpoint of
