three to four times as susceptible as A. rossii, whicli has hitherto been consid- 

 ered tlie malaria carrier of the Philippines, and eleven times as susceptible as 

 A. barhirostris. The number of mosquitoes of the species A. sinensis and A. 

 maculatus dissected, especially in the comparative experiments, is too small to 

 give reliable percentages. It is possible that a larger series of experiments with 

 A. sinensis would show that this species can be infected. . . . 



" The role plaj- ed by a species of Anopheles in the transmission of malaria in 

 any country depends chiefly upon (1) its susceptibility and (2) its geographical 

 distribution and prevalence; also, to some extent, upon (3) its avidity for 

 human blood and (4) its domesticity." 



A list of 21 references to the literature is included. 



On the life history of the pipuncTilids, intracoelomic parasites of 

 Typhlocyba, D. Keilin and W. Thompson {Compt. Rend. Soc. Biol. [Paris'\, 

 78 (1915), No. 1, pp. 9-12, figs. 11; ahs. in Rev. Appl. Ent, 3 {1915), Ser. A, 

 No. 5, p. 252). — It is pointed out that, aside from the discovery by Boheman in 

 1854 of the parasitism of ciccadellids by a pipunculid larva, the discovery by 

 Giard in 1889 of the parasitism of Typhlocyba by Atelenevra spuria, and the 

 fact that they usually oviposit in the bodies of Homoptera and may be employed 

 in controlling some species injurious to plants, such as sugar cane, very little 

 is known of their bionomics. 



The authors report upon studies of Typhlocyha rosw, T. Mppocastani, and 

 T. douglasi attacked by A. spuria and what is thought to be another pipunculid. 



A new Sarcophaga parasitic on Allorhina nitida, J. M. Aldeich (Jour. 

 Econ. Ent., 8 (1915), No. 1, pp. 151, 152, fig. 1). — A new dipteran reared from 

 pupae of A. nitida in Virginia, Indiana, Illinois, Michigan, Geox'gia, Florida, and 

 Louisiana is described as Sarcopliaga utilis. 



Notes on certain points of economic importance in the biology of the house 

 fly, F. 0. BisHOPP, W. E. Dove, and D, C. Paeman (Jour. Econ. Ent., 8 (1915), 

 No. 1, pp. 5ff-71). — This report of studies of the biology of the house fly con- 

 ducted in Texas includes tables which show in detail the preoviposition period, 

 developmental periods, and longevity of the house fly at Dallas. 



Note on the use of poisoned bait for controlling the house fly (Musca 

 domestica), G. W. Mally (So. African Jour. Sci., 11 (1915), No. 9, pp. 321- 

 328). — The author concludes that from the standpoint of expense the poison bait 

 method is very much cheaper than any other that has come to his attention. 



The effect of temperature on the life cycle of Musca dom.estica and Culex 

 pipiens, S. D. Kramee (Science, n. ser., U (1915), No. 1067, pp. 87^-877).— The 

 results of studies of the average duration of the egg, larval, and pupal stages 

 of the house fly at 20, 30, and 35° C. are presented in tabular form, as are 

 studies of the immature stages of mosquitoes (C. pipiens) at 20°, room tem- 

 perature, and 30°. 



The celery fly (Acidia heraclei), J. Feytaxtd (Bui. Soc. Etude et Vulg. Zool. 

 Agr., 13 (1914), No. 7, pp. 109-114, figs. 2; a1)S. in Rev. Appl. Ent, 3 (1915), 

 Ser. A, No. 4, p. 188) . — This dipteran is a source of injury to celery in southwest 

 France through its mining in the leaves. 



A new species of TJlidinae from Tucuman, J. Br£;thes (Bui. Soc. Ent. 

 France, No. 2 (1914), PP- 87, 88, fig. 1). — The new dipteran here described as 

 Euxesta chavannei is said to cause the decomposition of the young shoots of 

 the sugar cane, and the canes are then invaded by Bacillus sacchari which 

 causes a disease known as " polvillo."
