the remaining 7,027 specimens are being prepared for despatch as 

 quickly as possible. Up to the present two distinct broods of Stegomyia 

 fasciata have been found widely separated from each other in the city 

 of Victoria. All the others are apparently Stegomyia scutellans, 

 except for a single S. tv-alha, Theo.

 According to Dr. Watson, Sumatra, owing to the scarcity of Anopheles 

 maculatus there, is markedly free from malaria as compared with the 

 Federated Malay States.

 — La Vie Agric. et Rur., Paris, iii, no. 14, 7th March 1914, 

 pp. 373-378, 3 figs. 



The author records the following species of flies as associated with 

 the transmission of disease : the common house-fly, Musca domestica, 

 the small house-fly, Homalomyia canicidaris, the blue-bottle fly, 

 Calliphora vomitoria, a green and gold fly, Lucilia caesar, and the 

 stable flies, Sfomoxys ccdcitrans and Muscina sfabulans ; the two latter 

 being rare in chvelling houses. In view of their disease-bearing poten- 

 tialities, flies should be prevented access to dwelling houses wherever 

 possible. Various methods are given for destroying flies once they 

 have entered the house, such as traps containing soap solution, sticlcy 

 papers, pyrethrum powder either as a fumigant, slowly burned, or 

 as a powder, or formol mixed with milk. Bouet and Roubaud recom- 

 mend fumigating with " cresyl," the fumes of which act instantaneously 

 on flies and mosquitos, but are not harmful to metal work, leather, etc., 

 and beyond causing slight irritation to the eyes, are harmless to human 

 beings. Manure and rubbish heaps, etc., in which the flies breed, should 

 be as far away as possible and treated with larvicides such as chloride 

 of lime, a 20 per cent, solution of slaked lime, petrol and sulphate of 

 iron, a solution of borax and arsenate of soda, or crude oil mixed with 

 water. 



No very efficient natural enemies are known. They are preyed on by 

 species of Bembex, and the fungus Emqjusa muscae is very pathogenic 

 to them, but has not yet been successfully cultivated artificially.
