894 EXPERIMENT STATION RECORD. 



The yellow fly of the dismal swamp, N. Banks (Ent. Neivs, 15 {1904), No. 9, pp. 

 290, 291). — The yellow fly of the dismal swamp was identified as Diachlorus ferruga- 

 liis. This fly frequently attacks man, causing painful swellings. 



Lepidoptera taken in a moth trap at Ditching-ham, Suffolk, Mrs. H. E. 

 Mann (Ent. Mo. Mag., 2. ser., 16 (1905), No. 181, pp. 10-13).— Notes are given on 

 large and small lepidoptera captured in moth traps since 1901. The peculiarities of 

 the trap used in these experiments are briefly described. The variety of species cap- 

 tured was considerable and the author believes that this is a useful device to assist 

 collectors. 



Insecticides and fungicides, H. A. Gossabd and H. H. Hume (Florida Sta. Bui. 

 76, pp. 201-250, figs. 28). — General directions are given for the preparation of various 

 insecticides and fungicides including arsenic bran mash, Criddle mixture, arsenite of 

 lime, Paris green, green arsenoid, London purple, arsenate of lead, white hellebore, 

 whale-oil soap, kerosene emulsion, resin wash, lime-sulphur-soda wash, pyrethrum, 

 tobacco, bisulphid of carbon, hydrocyanic-acid gas, Bordeaux mixture, corrosive 

 sublimate, formalin, etc. 



The parasites of Culicidae, L. Dye (Arch. Par., 9 (1904), No. 1, pp. 5-77, figs. 

 6). — The habits of mosquitoes are briefly discussed with reference to the possibility 

 of parasitism from various sources. A brief systematic account is given of the 

 families and genera of the mosquitoes. 



Among the internal parasites which are known to affect mosquitoes a number of 

 bacteria and fungi are mentioned including Empusa culicis, a bacterial species resem- 

 bling Leptothrix buccalis, etc. Numerous animal parasites also occur in the bodies of 

 mosquitoes in different stages of development. Among these parasites mention is 

 made of species of Nosema, gregarines, hemosporidia, such as the malarial parasite, 

 etc., flagellate infusoria, trematodes, round worms, including various species of 

 Filaria, etc. As external parasites of mosquitoes, mention is made of certain fungi 

 such as the trichophyton infusoria, various species of mites, and diptera. Particular 

 attention is given to a discussion of the parasitic mites of mosquitoes. A brief 

 bibliography of the subject is appended to the article. 



Wintering of bees, Devauchelle (Apicultear, 48 (1904), No. 10, pp. 400-403). — 

 Brief notes on the internal temperature of bee hives during the period of hibernation, 

 and other matters relating to this question. 



FOODS— NUTRITION. 



Standards of purity for food products ( U. S. Dept. Agr., Office of Secretary, 

 Circ. 13, pp. 14)- — This circular is designed to replace the standards included in a 

 previous publication (E. S. R., 15, p. 702). The form of statement of the standards 

 previously proclaimed has been modified in some cases, and standards for grain 

 products, honey, fermented fruit juices, and vinegar added. The standards fixed 

 for grains and meals follow: 



"Grain is the fully matured, clean, sound, air-dry seed of wheat, maize, rice, oats, 

 rye, buckwheat, barley, sorghum, millet, or spelt. 



"Meal is the sound product made by grinding grain. 



"Zlour is the fine, sound product made by bolting wheat meal and contains not 

 more than 13.5 per cent of moisture, not less than 1.25 per cent of nitrogen, not 

 more than 1 per cent of ash, and not more than 0.50 per cent of fiber. 



"Graham flour is unbolted wheat meal. 



" 'Whole wheat flour,' 'entire wheat flour,' improperly so-called, is fine wheat meal 

 from which a part of the bran has been removed. 



"Gluten flour is the product made from flour by the removal of starch and contains 

 not less than 5.6 per cent of nitrogen and not more than 10 per cent of moisture.
