 1919, pp. 223-229, 2 plates. 



The occurrence of malarial parasites in the blood of ruminants has 

 not apparently been previously recorded except by Bruce, who 

 discovered two infected antelopes in Nyasaland in 1913 [R.A.E., B, 

 i, 99]. The author of the present paper records the finding of the 

 parasite in blood-smears taken in India from a plains buffalo after 

 death. The morphology of the organism is described and shows it 

 to be quite distinct from that recorded by Bruce. There was no 

 regular periodicity of the fever produced. An examination of the 

 blood corpuscles showed 1-6 per cent, containing parasites. Should 

 the parasite prove to be a new one, the name suggested for it is 

 Plasmodium huhalis. 



A further case of malarial infection in the buffalo has been discovered 

 since the above paper was written.

An account is given of the mosquitos occurring in Florida, which 

 include Culex fatigans, Wied. {quinquefasciatus. Say), Anopheles cru- 

 cians, Wied., A. quadrimaculatus, Say, Stegomyiafasciata, F. {calopus, 

 Meig.), Psorophora ciliata, F., P.floridensis, D. & K., and Megarhinus 

 sp. The various stages are described and their hfe-histories, breeding- 

 places and habits are discussed. A later paper will deal with 

 remedial measures.

Necrobia ruficollis, F., was bred abundantly in the " fly room " 

 at the Imperial College of Science, London, in 1917-18. The tempera- 

 ture ranged between 70° and 80° F. (about 21° and 27° C.) with 

 extremes of 64° and 89° F. (18° and 32° C). Breeding and general 

 activity apparently continued regardless of the temperature. The 

 work of previous authors with regard to the diet and behaviour of 

 N. ruficollis and aUied species is reviewed. 



The present observations show that the larvae are usually sapro- 

 phagous and only with great difficulty were induced to kill and eat 

 fly maggots. Pupation occurs in any suitable existing cavity, 

 especially in the interior of a fly puparium, for which purpose a cell 

 is made by the larva. Pupation does not occur immediately after
