Allied (Nonbiting) Flies in the Spread of Infective Diseases — A Summary of 

 our Present Knowledge, by G. H. F. Nuttall and F. P. Jepson (pp. 13-30). 



An extensive bibliography accompanies the last-mentioned paper. 



The relation of mosquitoes to filariasis in the region of San Francisco Bay, 

 C. Wellman, E. von Adelung, and F. M. Eastman (Jour. Aiuer. Med. Assoc, 

 55 {1910), No. 3, pp. 217, 218). — The authors consider that they have shown by 

 the experiment reported that the 2 commonest species of Culex mosquitoes in 

 Oaliland, Cal. (Culex consobrinus and C. tarsalis) were not efficient hosts at 

 room temperature for the nocturnal sheathed microfilariae occurring in a 

 Japanese patient. They conclude that there is probably little danger that 

 Orientals who are infected with filarise will infect the inhabitants of the San 

 Francisco Bay cities under present conditions. 



Hibernation of mosquitoes in northern China, H. I. Cazeneuve (Bui. Soc. 

 Path. Exot., 3 (1910), No. 3, pp. 155-159). — Observations made on Anopheles at 

 Chinvan-tao, a small port on the frontier of the province of Chili, and of 

 Manchuria, are thought to show that the winter is largely passed in the egg 

 stage. It is stated that the winter is so rigorous in this region that the suc- 

 cessful hibernation of adults and larvae appears to be the exception. 



The present epidemic of malaria in the port of Bombay: A description of 

 the mosquito which is carrying the disease, with some remarks on pre- 

 ventive measures, W. G. Liston (Jour. Bombay Nat. Hist. Soc, 18 (1908), No. 

 4, pp. 872-881, pis. 4). — Anopheles stephensi was the species responsible for the 

 transmission of malaria in Bombay, nearly 25 per cent of these mosquitoes 

 when dissected being found to harbor the malaria parasite in some stage of its 

 development. It is said that A. rossii, which is met with all over Bombay, has 

 never been observed to be infected in nature. 



Health progress and administration in the "West Indies, R. W. Boyce ( Lon- 

 don, 1910, pp. XV +328, pis. Ji7, map 1). — A report upon the results obtained in 

 combating mosquitoes in the West Indies. See also a previous note (E. S. R., 

 22, p. 556). 



Phlebotomus or sand-fly fever, C. Birt (Brit. Med. Jour., 1910, No. 2595, 

 Epit., pp. 875-878). — The experimental evidence here presented shows that the 

 sand-fly of Malta (Phlebotomus papatasii) can convey the virus of this fever 

 and that the bite of only one fly is sufficient for the purpose; also that the sand- 

 flies are infective from 7 to 10 days after sucking virulent blood. This afliection, 

 which is prevalent throughout the Mediterranean area, is said to be of short 

 duration and to cause no mortality. 



On fever caused by the bite of the sand-fly (Phlebotomus papatasii), T. G. 

 Wakeling (Brit. Med. Jour., 1910, No. 2598, pp. 1115, 1116).— An account of 

 this nonfatal, 3 days' fever, which is known to exist in Egypt, parts of Austria, 

 in Malta, and in Italy, and which it is thought will be found widely distributed. 



A report of two cases of external myiasis, J. M. Swan (Jour. Trop. Med. 

 and Hyg. [London], 13 (1910), No. 1, pp. 1-3, pi. l).—LuciUa sericata and 

 L. ccesar were implicated in the 2 cases here reported from Philadelphia, Pa. 

 The length of time required for the development of L. sericata from egg to 

 adult fly was found to be between 15 and 16 days. The eggs apparently de- 

 veloped into larvse within 24 to 48 hours. The larvfe pupated in 3 or 4 days 

 and images emerged 10 days later. The development of L. ccesar from egg 

 to imago required from 19 to 20 days. It is estimated that the larvse emerge 

 from the egg in 12 hours. From 8 to 9 days are passed as larvse and from 10 

 to 11 days as pupse. 



The development of trypanosomes in tsetse flies, D. Bruce et al. (Jour. 

 Roy. Army Med. Corps, 15 (1910), No. 4, pp. 422-U3) .—The conclusions arrived 

 at are that Trypanosoma gambiense multiplies in the gut of about one in 20
