in flooded rice stubble. It has been ascertained that after feeding, the great majority of these Anophelines leave the building, hence do not figure to any extent in day catches, as was conjectured in the 1932 report. In the Shing Mun collections they were obtained in large numbers in the latter part of the year following screening of the lines and have been found infected with malaria but not in the collections from elsewhere. They have been found infected with larval filaria in the thorax, head and proboscis.
A. jeyporiensis. Larvae of A. jeyporiensis were found to breed in profusion in water on abandoned rice fields in hilly country. They have been found along with those of A. hyrcanus in the stubble of rice fields situated at the foot of hills, but adults previously absent from catches in this locality began to appear before the rice was cut whilst the water was being drained off. They were found in terraced rice fields in hilly country during the month of October along with the larvae of A. hyrcanus and A. minimus when the crop was almost ripe and the water was being drained off. The larvae were met with occasionally in hill streams, but so far, such sources have not been found to contribute to any appreciable extent.
This mosquito was found to be a most important carrier of malaria. Large numbers were dissected in 1933 as compared with 1932 when it was only found infected during the last quarter of the year. It has been found infected with filaria. At the Shing Mun Camp large numbers were captured and in certain directions its range of flight much exceeds half a mile. Most likely the variety candidiensis is the sole representative of the species to be found here.
A. karwari, A. aitkeni and A. splendidus. Larvae of A. karwari, A. aitkeni, A. splendidus (maculipalpis) were obtained only in small numbers. A few adults of A. karwari and A. splendidus were captured in houses. No larvae of A. tesselatus were encountered and no adults were taken.
