This paper contains a description of Skuse's types in the above 

 Museum, at the University of Sydney. The author proposes to refer 

 Anopheles stigmaticus and A. atratijjes to Pyretophorus, Cidexflavifrons 

 and C. vittiger to Culicada, and to give a new name to Grabhamia 

 flavifrons, Theo. Cidex linealis is placed in Culicelsa, while C. atripes 

 is transferred to Scutomyia and shown to be distinct from Stegomyia 

 pundolateralis, Theo. 



Jack (R. W.). Report of Expedition to Sebungwe District, Southern 



l^ho^Qsidi.— Salisbury, 14th Nov. 1913. [Received 30th March 1914.] 



This expedition was undertaken between 25th August and 1st 

 November 1913, to investigate the distribution of G. morsitans in the 

 Sebungwe District of Southern Rhodesia. The main object of the 

 trip, which aimed at improving the existing map of the infested country 

 between the Sengwa and Umniati Rivers, was accomplished. Notes 

 as to the distribution of the fly bore out previous experience in the 

 dry season, the insect being confined to the shady banks of water- 

 courses and vleis, and apparently only crossing a watershed if carried. 

 The author, on one occasion, saw five tsetse-flies carried for six miles 

 across a watershed on the back of a native and thinks this may often 

 happen, but believes that the majority of specimens so carried make 

 their way back to their old haunts when no serious barrier intervenes, 

 otherwise the spread of the fly would be more rapid than is actually 

 the case. On the Sengwa side, game is everywhere abundant in the 

 fly-belts, but towards the southern end of the Umniati belt both fly 

 and game are much scarcer. There is, however, abundant evidence 

 that game is much more plentiful near the Umniati in the wet season. 

 Game is also plentiful in many parts not infested by tsetse. Since 

 the opening of part of the district to shooting, a large number of himters 

 have been there, but they are almost without exception in search of 

 elephants, and the antelopes are left unreduced, except for those killed 

 by sportsmen ; such shooting is regarded as hardly likely to effect 

 the removal of the reservoir of trypanosomiasis. 



Fleming (Dr. A. M.). Report on the Public Health for the year 1913, 

 Southern Rhodesia. — Salisbury, 1914, 46 pp. 

 Seven hundred and seventy-nine persons out of a population of 

 30,344 were admitted to hospital in Southern Rhodesia during 1913 

 suffering from malaria, of which 13 died, as compared with 770 cases 

 and 6 deaths in 1912. These cases however in no way represent the 

 true malarial incidence in the country generally, as a large proportion 

 of cases are treated in their own homes, frequently without medical 

 assistance. There were 57 cases of black water fever as compared with 

 60 in 1912. The relation of malaria and blackwater fever, both to 

 each other and to the rainfall, has been investigated, and it was found 

 that blackwater fever is at its maximum some thirty days after that 

 of malaria has been reached. Malaria commences to increase about 

 thirty days after the advent of the early rains, and reaches a maximum 

 in May, about three months after the greatest rainfall, and almost
