that research be made by competent observers among the Glossinre for micro- 

 sporidian parasites allied to the Nosema of bees, and, possibly, equally patho- 

 genic to the tsetse flies that may harbor them." 



The evolution and larval forms of Diachasma crawfordi n. sp., D. Keilin 

 and C. PiCADO {Bui. ScL France and Belg., Ifl (1913), No. 2, pp. 203-21.'f, pi. 1, 

 figs. Jf). — The braconid parasite of the fruit fly Anastrepha striata here de- 

 scribed as new was discovered by the authors while conducting studies in 

 Paris of material brought from Orosi, Costa Ilica, where this fly highly infests 

 the guava (Psidium). It is thought that this may be the same as the para- 

 site collected by Crawford (E. S. R., 25, p. 50) in Mexico, and which, appar- 

 ently unknown to the present authors, was described by Viereck (E. S. R., 

 26, p. 352) as D. crawfordi. Some 10 per cent of fruit fly larvre were found to 

 be parasitized. It is stated that Biosteres hrasiliensis and B. areolatus have 

 been reared from pupae of A. fraterculus from Brazil. 



The brown-tail and g^ipsy moths and parasites, E. E. Philbrook (Bui. 

 [Maine] Dept. Agr., 12 (1913), No. 4, pp. 18, pis. 11). — A detailed discussion ol 

 these pests with an account on Parasite Introduction into Maine, by A. M. G. 

 Soule (pp. 10-18). 



Hereditary infection, with special reference to its occurrence in Hyalomma 

 segyptium infected with Crithidia hyalommse, W. R. O'Faerell (Ann. Trop. 

 Med. and Par., 7 (1913), No. 4, pp. 545-562, pis. 5).—" C. hyalommw is a flagel- 

 late parasite occurring in the hsemocoelic fluid, salivary glands, ovary, oviducts 

 and ova of H. wgyptium, the common cattle tick of the Anglo-Egyptian Sudan. 

 The parasite has 4 periods in its life cycle, a preflagellate stage passed chiefly 

 in the hsemocoelic fluid, a fln gel late stage in the h^emocoelic fluid and in the 

 ovary and oviducts, a posttiagellate stage in the hiemocoelic fluid, and a post- 

 flagellate or ovarian stage in the ovary and oviducts, ovarian cells, and ova. . . . 



" Multiplication of C. hyalommw by longitudinal division takes place in all 

 its stages. Infection of H. cegyptium by C hyalommw in the adult is purely a 

 hereditary infection. The flagellate is a strictly parasitic flagellate of the 

 tick, and is nonpathogenic to the tick host." 



FOODS— HUMAN NUTRITION. 



The chemical milling and baking value of Utah wheats, R. Stewart and 

 C. T. Hirst {Utah 8ta. Bui. 125, pp. 115-150). — Additional data are reported 

 regarding the studies of Utah wheats which have been carried on (E. S. R., 

 25, p. 263). The necessity for standardizing western grains is insisted upon 

 and the details given of studies of 1907-1909 spring wheats and winteV wheats 

 grown under dry-farming conditions and of irrigated wheats. 



The authors summarize the data regarding the yield and composition of the 

 milling products, the composition of the flours, and the bread making qualities 

 of these wheats as follows: 



" The weight per 100 kernels of the irrigated wheat is greater than that of 

 either the spring or winter dry-farming wheat. The yield of flour, bran, and 

 shorts shows nothing characteristic. . . . 



" Nothing characteristic is shown with respect to the moisture content except 

 that it is low in every case. The protein content of irrigated wheat is lower 

 than that of either the spring or winter dry-farm wheat. The spring wheat 

 contains the highest protein content. The bran and shorts produced from the 

 irrigated w^heat have a lower protein content than that produced from dry- 

 farm wheat. . . . 



" The flour produced from the winter dry-farm wheat has a slightly lower 

 moisture content than the flour produced from the other kinds of wheat. The
