552 EXPERIMENT STATION RECORD. 



The life of the fly, J. H. Fabre {Hiew York, 1913, pp. 477).— A popular work 

 containing a translation of all the essays on Diptera from the author's 

 Souvenirs Entomologiques. 



The Syrphidse of Ohio, C. L. Metcaxf (Ohio State Univ. Bui, 17 {1913), 

 2V^o. 31, pp. 123, figs. 255).— This paper treats of the subject in three parts. 



The first (pp. 12-52) consists of a general discussion of the family; general 

 characters of the egg, larva, pupa, and adult; an evolutionary table of larval 

 habits; biological and ecological relations and economic importance of the 

 larv£E; ecological relations and economic importance of the adults; enemies; 

 and practical measures. The second part (pp. 52-74) consists of a key to 

 known larvae of Syrphidse; synopses of life histoi-y studies of 10 species, sev- 

 eral of which have been previously noted (E. S. R., 29, p. 456) ; and a generic 

 review of the literature on the biology of Syrphidse. The third part (pp. 

 74-100) consists of a key to the genera of Syrphidse; list of Ohio species with 

 keys to the species and various genera which have been, or are likely to be, 

 collected in the State ; and a bibliography of 23 titles. 



Fruit flies of Fiji, J. F. Illingworth (Hawaii. Forester and Agr., 10 {1913), 

 No. 12, pp. 366-370). — Four species of fruit flies of the genus Dacus have been 

 reared from fruit in the Fiji Islands, namely, the Fiji fruit fly {D. passi- 

 floriw), from granadilla fruits and mangoes; the pineapple fruit fly {D, 

 xanthrodes^) ; the South Sea guava fly (D. psidii) ; and the banana fruit fly 

 (D. curvipennis). 



The occurrence of the warble fly, Hypoderma bovis, in Canada, C. G. 

 Hewitt {Canad. Ent., 46 {19U), No. 1, pp. 1, 2).— The author reports records 

 of the occurrence of H. hovis which show it to be widely distributed in Canada 

 from the Atlantic to the Pacific. 



Flies in relation to disease. — Nonbloodsucking flies, G. S. Graham-Smith 

 {Cam'bridge, England, 1913, pp. XIV-\-292, pis. 24, figs. 32).— In the preparation 

 of this book the author has attempted to collect the most important and re- 

 liable information available on the subject. In addition to accounts of the 

 anatomy and biology of flies, methods employed in studying them, bacteriology 

 and ways in which bacteria are distributed, and their relation to specific 

 diseases, he discusses the part played by flies in the disi^ersal of the eggs of 

 parasitic worms, myiasis, diseases, parasites, and enemies of flies, flies breed- 

 ing in or frequenting human feces, and prevention and control of flies. 



A bibliography of 17 pages and author and subject indexes are included. 



The conservation of pathogenic bacteria by flies during hibernation, V. 

 BfiRiisoFF {Russ. Vrach., No. 26 {1913), pp. 917-921; ahs. in Presse Med. 

 [Paris], No. 93 {1913), p. 939). — Studies were made of 150 flies collected in St. 

 Petersburg hospitals after a hibernation of from 4 to 5 months. After having 

 been washed in a sublimate solution to destroy all micro-organisms on the sur- 

 face of the body, cultures w^ere made from the digestive tube which showed 

 the presence of Staphylococcus pyogenes alhus, S. pyogenes aureus, Proteus 

 mirahilis, Bacillus coli, and three additional varieties of S. pyogenes. The 

 intraperitoneal injection of a culture of one of the streptococci killed a mouse 

 In 24 hours. In addition to the above mentioned species the author isolated a 

 large number of micrococci and bacilli nonpathogenic for man, and also 5 

 micro-organisms which did not appear to have been previously described. Thus 

 the investigations show that a large number of pathogenic micro-organisms are 

 conserved alive in the flies during hibernation. 



Hydrotaea dentipes, its biology and the destruction by its larvae of the 

 larvae of Musca domestica, I. A. Portchinsky {Trudy Biuro Ent. [St. 

 Petersl).'\, 9 {1913), No. 5, pp. 30, figs. 23; al)s. in Rev. Appl. Ent., 1 {1913), 

 Ser. B, No. 9, pp. 149-152). — The author here reports studies of H. dentipes
