A preliminary survey of tlie mosquitos m the town of Madras 

 showed that Stegoinia fasciata is more widespread than *S'. scutel- 

 laris, the former species being essentially a house mosquito, 

 whereas the latter is common where there are trees, and is 

 apparently an outdoor mosquito. Occasionally the author has 

 been bitten by S. fasciata between 7 and 10 p.m. Stegomyia 

 sugens, Desvoidya sp. and probably a Reedoviyia were also found. 

 The breeding places are enumerated and their elimination 

 recommended.

Stegomyia fasciata, S. scutellaris and Devoidya ohturhans have 

 been found to breed in Rangoon. The breeding places are 

 enumerated and an account of laboratory experiments given 

 which were conducted with a view to the discovery of a cheap and 

 effective larvicide. The following alone were found to satisfy the 

 required condition: Cyllin, 1 in 1,250; and coal tar and turpen- 

 tine in equal parts, emulsitied with '075 grms. of Hudson's 

 extract of soap to each cc, 1 in 2,500.

The author has been conducting experiments on laboratory 

 animals with blood-sucking arthropods at Chosica, Peru, with a 

 view to solving the verruga problem. At first he inclined to the 

 view that the disease is transmitted by Acari, but as no Argasid 

 ticks commonly occur on mammals in the verruga zones, and the 

 presence of Ixodid ticks will not explain the night infection, such 

 transmission now seems improbable. The experiments upon 

 animals with the blood-sucking gamasid mites of the vizcacha 

 have led to no results. Culicids, Simulitim, Tabanids, Stomoxys,
