66 EXPEEIMENT STATION EECOED, 



tratiou, of a mechanical device constructed by the author the use of which 

 combines in one process cultivation of the crop and the drawing of fallen in- 

 fested squares to the middles of the rows, where they are exposed to the heat 

 of the sun, resulting in the killing of the weevil stages. The device is of special 

 value during periods of hot, dry weather on soils that are not baked. A full 

 description of this drag is given in Farmers' Bulletin 344, of this Department, 

 previously noted (E. S. R., 20, p. 853). 



A new parasite of the chinch bug' egg, J. W. McColloch and H. Yuasa 

 (Ent. Neivs, 26 {1915), No. //, pp. U7-l.'f9, figs. 5).— During the course of inves- 

 tigations of the life history of the chinch bug egg parasite at the Kansas State 

 Agricultural College, an account of which parasite has been previously noted 

 by Gahan (E. S. R., 31, p. 355), the authors have reared a second parasite that 

 has been determined as Abella subflava. 



A parasite of the cottonwood borer beetle, H. B. Hungerford (Ent. News, 

 26 (1915), No. 3, p. 135). — Over 90 per cent of the cottonwood borer beetles 

 (Plcctodcra scalator) collected in western Kansas in 1913 are said to have been 

 parasitized by Sarcophaga vcricauda, a species hitherto reared only from grass- 

 hoppers.

FOODS— HUMAN NUTRITION. 



The lye hulling of corn for hominy, J. W. Marden and J. A. Montgomery 

 {Jour. Indus, and Engin. Chcin., 7 {1915), No. 10, pp. 850-853). — Experimental 

 data are reported of work undertaken to study the effect of different substances 

 on the hulling of corn and the details necessary to secure the best product. 



Solutions of salt, acetic acid, hydrochloric acid, and calcium clilorid, used as 

 a substitute for lye, were entirely inofTective ; sodium bicarbonate partially 

 luilled the corn after several hours' heating, and both soda lime and lime worked 

 fairly well. Lye proved to be the only substance wliicli gave satisfactory results. 



Not more than 2 lbs. of lye to 12 gal. of water was necessary for good hulling, 

 while one-half of this concentration was nearly as efficient. The authors con-
