12. A. jeyporiensis. As in 1933 the larvae were found in flooded rice fields which had gone out of cultivation, in cultivated rice fields in October and November, and sometimes in pools amongst the rice stubble.
13. It was found to be an important carrier of malaria and to harbour larval filaria as in previous years.
14. A. karwari, A. aitkenii var. bengalensis, A. splendidus. Larvae of these were infrequently met with, a few adults of A. karwari and A. splendidus were captured. In the case of A. splendidus, two midgut infections were recorded from the Shing Mun captures and one instance of infection with larval filaria.
15. No larvae of A. tesselatus were collected and no adults captured.
16. Specimens of larvae and imagines were received from Dr. Toumanoff. Specimens were forwarded to Professor Gater, Singapore, for use in connection with the courses of Instruction held there under the auspices of the League of Nations, also to Dr. Toumanoff, to Captain Trimble, R.A.M.C., and to Dr. Dunscombe, Shanghai.
17. Dissections mounted on slides were given to Dr. Scharff, Senior Health Officer, Penang, and to Dr. Barnes of U. S. Public Health Service, Hong Kong.
Precipitin Tests.
18. Blood from midguts of Anophelines captured at Shing Mun, Wo Li Hop, and Little Hong Kong, were sent to Dr. Toumanoff, Pasteur Institut, Saigon for examination and report. The results are given in Table III.
19. At Shing Mun, where there are no cattle, 89% of the mosquitoes were positive for human blood. Goats are kept at times by the Indian Police.
20. At Wo Li Hop 83% of the Anophelines were positive for cattle blood. There are no cattle at Little Hong Kong.
21. It is hoped to send more material to Dr. Toumanoff who is making an extensive study of this subject, and also of the maxillary index of Anophelines, the results of which will be published by him later.
