weather. What appears to be a species of Culicoides has also been found on C. fatigans. Larvae found in a pitcher plant by Dr. Herklots were identified as those of Armigeres magnus, and a species of Culex. By hatching out single larvae and mounting the larval and pupal skins thrown off, endeavours were made to obtain as many specimens as possible of mosquitoes and the corresponding skins. It would seem by this method that other spotted wing species of Culex akin to Culex mimeticus are to be found in this part of the world. Mounts of the Culicine larvae in pure Carbolic ringed with Canada Balsam, have turned out most satisfactory.
Specimens of larvae have been received from Dr. Hu, Nanking, and of mosquitoes from Dr. Li, Hangchow. Specimens of mosquitoes and their larvae have been sent to Dr. F. W. Edwards, British Museum, Dr. W. V. King, Mosquito Investigations, Bureau of Science, Manila, to Major Covell and Captain Barrand (Malaria Survey of India, Kasauli), to Dr. Li, Bureau of Entomology, Hangchow, and Dr. Hu, Nanking.

Malaria.
From the results of the dissections of Anophelines done during 1932, it is seen that A. minimus is an important carrier in the Colony. During the last quarter of the year A. jeyporiensis was also found infected. It is hoped during the coming year to get a larger number of dissections done in the early months than were done in 1932 in order to ascertain with greater certainty how matters stand as regards the infection rate during this period. It would appear from the 1932 dissections that malaria is more prevalent in the second half of the year, no infected glands being found until the middle of June when over five hundred A. minimus had been dissected from a malarious area. If this is borne out by further research the incidence in the first half must be largely due to relapses and infections from the previous year. Records obtained from the R.A.M.C. authorities indicated, as formerly, a much higher incidence for the second half of the year, forty-one fresh cases out of a total of forty-five fresh cases amongst British troops; eighteen out of twenty-four amongst Indian troops. The figures for Lai Chi Kok Gaol (male) which is close to a hill stream where A. minimus has been found, were eighty-seven cases of malaria for the year, sixty-six of which occurred from July onwards. The 1930 and 1931 figures show the same seasonal incidence. Amongst the Government servants (excluding coolies) out of one hundred and fifty-one cases diagnosed as malaria, one hundred and thirteen occurred during the latter half of the year as was similarly found in 1930 and 1931.
Statistics for 1932 obtained from M.O.H. show that 455 deaths were ascribed to malaria in the Colony and New Territories, these being 2.28 per cent of the total deaths. The death
