Occurrence of the Argentine ant in Texas, W. Newell {Jour. Econ. Ent., 

 7 {1914), No. 1, p. 153). — irkJomyrmex humiUs was found throughout a con- 

 isiderable portion of the business and residential sections of Beaumont, Tex., on 

 January 5, 1914. 



A natural enemy of the Argentine ant, W. Newell {Jour. Econ. Ent., 7 

 {1014), No. 1, p. 147). — Ec-iton {Acamatus) schmitti has been found to be very 

 active in raiding colonies of Iridoinyrnicx humility, destroying the adults and 

 carrying off the larvte and pupie in the Louisiana citrus growing section. 



Calliephialtes in California, H. S. Smith and E. J. Vosler {Mo. Bui. Com. 

 Hort. Cal, 3 {1914), No. 5, pp. 195-211, figs. i5).— This is a report of studies of 

 this codling moth j)arasite in California which were commenced in the spring 

 of 1913. The information presented is supplementary to that by Cushman in an 

 article previously noted (E. S. R., 30, p. 360). 



'• On account of the wide differences in handling the apple crop in CaUfornia 

 and that of the native habitat, the physical limitations of the parasite, the 

 fact that the birds destroy a large percentage of the codling moth larvaj, and 

 the habits of the codling moth larvae seeking hibernating quarters, we believe 

 that Calliephialtes sp. will be of no practical value in controlling the host." 



Some information on the parasites of the eggs of Eurygaster integriceps, 

 X. A. DoBRovoLSKi {Ent. Vtestnik [Kief], 1 {1913), No. 2, pp. 229-236; abs. in 

 Rev. Appl. Ent., 1 {1913), Ser. A, No. 11, pp. 450, 451).— The proportion of eggs 

 j)arasitized in the Government of Kharkof was found to vary from 88 to 9t5 per 

 cent, from 37..5 to OS i)er cent being parasitized by Telenomus scmistriatus, 2G.7 

 to .50 j)er cent by T. Hokolori, and 1.3 to S.S per cent by a new species. 



The Tenthredinoidea of Argentina, P. Jorgensen {An. Miis. Nac. Hist. Nat. 

 Buenos Aires, 24 {1913), pp. 247-288, pis. S, fig. i).— This paper includes de- 

 scriptions of 3 genera and 13 species new to science. 



Ammonia gas as a fumigant, D. E. Fink {Jour. Econ. Ent., 7 (1914), No. 1, 

 pp. 149, 150). — Three oz. of concentrated ammonia, placed in a fumigation box 

 of 8s cu. ft. capacity with 6 qt. bags of cowpeas containing living weevils, re- 

 sulted in 100 per cent mortality. The same amount placed in the same box 

 with a 50-lb. bag of cowpeas and an exposure of IS hours gave from 75 to 85 

 per cent mortality. 



FOODS— HUMAN NUTRITION. 



The milling and baking qualities of Victorian wheat, A. E. V. Richardson, 

 P. R. Scott, and F. H. Winslow {Jour. Dept. Agr. Victoria, 11 {1913), Nos. 9, 

 pp. 521-533, figs. 6; 10, pp. 625-639, figs. 6; 12, pp. 755-765, figs. 2).— In the first 

 of these papers the small milling plant and electric baking oven and the 

 laboratory equipment installed in the Victoria Department of Agriculture, for 

 use in milling and baking tests with A'ictorian wheats and flours, are de- 

 scribed, the structure of wheat discussed, and some analytical data reported. 



A representative composite sample of Victorian wheat (1911-12) of "fair 

 average quality" had, according to the authors, the following percentage com- 

 position: Water, 10.43; protein, 11.26; crude fiber, 2.32; nitrogen-free extract, 

 71.97; ether extract, 2.79; and ash, 1.23. As shown by the average of 10 

 typical Victorian wheats, the total ash was made up as follows: Ferric oxid, 

 0.5 ; alumina, 0.58 ; brown oxid of manganese. 1.62 ; lime. 3.72 ; magnesia, 14.61 ; 

 potash. 29.93 ; soda, 3.24 : chlorin. 0.9 ; sulphuric auhydrid, 3.02 ; phosphoric 

 anhydrid, 40.87; and silica, 1.51 per cent; a total of 100.5 per cent, or 100 per 

 cent when 0.5 per cent oxygen (=chlorin) is deducted. The chemical testing 

 of flour is described in detail. 



In the second paper the methods followed in milling wheat and testing flour 

 are des.-'ribed at length, tbe descriptions being elucidated by data comparing 

 Victorian with New South Wales and South Australian wheats.
