An account is given of a severe epidemio of malaria that occurred in 

 1917 in the State of S. Paulo. Of 1,400 persons on one estate, 1,300- 

 were affected and 17 deaths occurred. The use of quinine and the 

 clearing of the neighbouring streams and their banks were the 

 measures adopted. They are fully described and proved entirely 

 successful, no fresh cases having occurred during a period of 15 months. 



Sturtevant (A. H.). Flies of the Genus Drosopkila as possible 

 Disease Carriers. — Jl. Parasitology, Urbana, III., v, no. 2, December 

 1918, pp. 84-85. 



Observations are recorded upon certain species of DrosopJiihy 

 which are of some importance as possible carriers of typhoid or other 

 diseases. All are known to feed more or less upon human excrement. 

 D. melanogaster, Meig. {anipelophila, Lw.) is a cosmopolitan species^ 

 which, although it has been recorded as an excrement fly, is considered 

 by the author to infest chiefly decayed fruit and to be of Mttle or 

 no importance as a disease carrier. D. caribbea, Sturt., which is 

 common throughout the American tropics, has very similar habits 

 to D. melanogaster, but is nmch more frequently attracted to excrement. 

 D. biiscki, Coq., and D.funebris, F., while probably breeding in excre- 

 ment, are not likely to be important as disease carriers, as they are 

 not common near food. The former also breeds in badly decayed 

 potatoes and other foodstuffs. D. repleta, Will., is commonest near 

 houses, where it is attracted to various organic substances and is 

 frequently found resting on a white surface. It is easily collected 

 about latrines and also in kitchens and restaurants. D. repleta has 

 a wide range of breeding habits. It breeds in banana, pineapple, 

 tomato and other fruits, in decayed potato, flour paste, moist bran, 

 and similar substances, and although it has not been bred from excre- 

 ment it undoubtedly feeds upon it.
