per morning, about one-third of the catch obtained from the northern group. It would thus appear that habitations closest to the breeding places receive most attention from this Anopheline.
41. As in former years the majority of the A. jeyporiensis were obtained in the last quarter of the year although there is now no rice cultivation in the area. No A. fluviatilis were captured in the rainy months. Table VI gives the results of morning catches, and Table VII of the dissections.
42. In this locality A. minimus adults can be obtained throughout the year without difficulty, but comparatively few A. maculatus or A. hyrcanus were ever got in either day or night catches from human habitations, in spite of the fact that their larvae can be collected in abundance in the neighbourhood.
43. During the latter half of 1935 catching was done in two pigsties, one at the head of the main valley near the village of Little Hong Kong, the other at the head of the former Rice Ravine. The catchers remained in the pigsties for an hour and a half from dusk onwards and by means of a torch light and catching apparatus, collected such mosquitoes as could be seen resting on the walls or roof. Catching was done every night except Saturdays, Sundays, and holidays. Out of 524 Anophelines thus obtained, approximately 40% were A. maculatus, 45% A. hyrcanus, 7% A. minimus, 7% A. tessellatus, 1% A. jeyporiensis. No infections were found amongst 493 dissected.
44. These operations were repeated throughout the present year. Catching was done during 301 nights; 2319 Anophelines were captured, 2088 dissected, 78 were subjected to precipitin tests. Of those captured 1211 were A. hyrcanus, 874 A. maculatus, 106 A. minimus, 71 A. jeyporiensis, 33 A. tessellatus, 24 A. fluviatilis. The majority of the dissections were done in the malarious season; no infections were found in 101 A. minimus, 16 A. fluviatilis, 70 A. jeyporiensis, 754 A. maculatus, 1123 A. hyrcanus, 24 A. tessellatus.
45. The results of the precipitin tests are given in Table X. All the A. hyrcanus and A. maculatus tested reacted to anti-pig serum.
46. Taking all these factors into consideration, it would appear that A. hyrcanus and A. maculatus are of no importance in the spread of malaria in this locality, owing to their partiality for pig blood.
