872 EXPERIMENT STATION RECORD. 



Insect injurious to rosaceous plants, E. LUCET (Bui. Soc. Cent. JTort. Seine-In f 6- 

 rieure, .'. ser., 2(1898), No.5, pp. 321-359, pis. ^.-^The present paper treats principally 



of scarabids and curculios. 



New genera and species of Australian Coleoptera, T. Blackburn ( Trans. Hog. 

 Soc. South Australia, 22 (189S), No. J, pp. 221-233). 



Notes on Australian Lepidoptera, A. J. TURNER ( Trans. Hoy. Sue. South Australia, 

 : : i 1898), No. 2, pp. 90-100. pi. 1). 



Descriptions of new Microlepidoptera, A. J. Turner ( Trans. Roy. Soc. South 

 Australia, 22 (1898), No. 2, pp. 200-214). 



The Hessian fly,W. G. Johnson (Maryland Sta. Bul.58,pp. 117-122, fig. I). — A brief 

 popular account is given of the Hessian fly, its distribution throughout the State, 

 and the best means for its suppression and control. 



The ravages of Bombyx pini in Siedlec, Russian Poland (Oesterr. Forst. u. 

 Jagdw. Ztg., 17 (1S99), No. 6, p. 43, figs. 2). 



Recent investigations of the European ccale insects in comparison "with the 

 San Jose scale, Frank (Gartenflora, 4S (1S99), No. 3, pp. 57-66). 



Experiments in combating Cochylis ambiguella, A. Battaglini (Hal. Knt. 

 Agr. e Patol., 5 (1898), Nos. 1, 3, 4, 5; abs. in Ztschr. Pflanzenkrank., 8 ( 1898), Xo. 5, 

 jip. 311, 312). — Experiments with finely powered sulphur and 2 per cent rubin, and 

 with preparation made of Bordeaux mixture and rubin, are reported. In addition 

 to having valuable insecticidal properties, they also reduced the amount of mildew 

 present. 



Experiments in combating Cochylis ambiguella, A. Berlese (Bol. Knt. Agr. e 

 Patol., 5 (1898),pp. 51-53; abs. in Ztschr. Pflanzenlcrank., S (1898), No. 5, p. 312).— The 

 author reports favorably upon -what is known as Martini's mixture for the suppres- 

 sion of this insect. This mixture is composed of Bordeaux mixture and ruliin a. id 

 has an important fungicidal action. Soap emulsions were found to be valueless in 

 combating this insect. 



FOODS— ANIMAL PKODUCTION. 



Food and food adulterants, II. W. Wiley et al (JJ. S. Bept. 

 A</>\, Division of Chemistry Bui. 13, pt. IX, pp. VII + 1169-1374, pis. 7, 

 fitjs. 1). — This bulletin is an extended treatise on cereal grains and the 

 products made from them. The composition of different grains and 

 their various constituents are discussed on the basis of bulletins 9 and 

 45 of the division. The various constituents of different grains are 

 spoken of in detail as well as methods of preparing cereals for food and 

 the method of making and baking bread. The work of many investi- 

 gators on the insoluble carbohydrates of wheat is cited, and investiga- 

 tions conducted by the Division of Chemistry are reported. Following- 

 are some of the chief results : 



"As determined by the analysis of the osazones, only the pentoses, xylose, and 

 arabinose result from the hydrolysis of the hemicellulose. This is, therefore, prac- 

 tically identical -with the free or normal pentosans which the wheat contains. 



" The preparation of cellulose from the liber insoluble in dilute acid was found to 

 be best effected by means of alkali and chlorin as described by Cross and Bevan. . . . 



"The cellulose obtained as just mentioned, or by fusion of the fiber with strong 

 alkali (Lange's method), contains furfuraldchy de-yielding bodies whose deportment 

 toward reagents indicates the presence of penta-anhydrid, probably in combination 

 with apart of the hexanhydrid or normal cellulose. When dissolved in sulphuric 

 acid, diluted, and hydrolyzed, a small quantity of dextrose only was obtained as 

 osazone. 



"The property of dyeing in a solution of ferric chlorid and potassium ferricyanid 

 is possessed in a marked degree by the wheat fiber, and the reaction has been found
