39. Larvae of T. vicina, A. (S) albopictus, A. (F) niveoides (Bar.) were collected from various tree holes at various times, and adults hatched out. On several occasions whilst making the collections adults were captured, amongst them being A. (S) walba, but so far the larvae of this species have not been obtained, and attempts to get them from captives did not succeed, even though these mosquitoes could be induced to take blood in the Laboratory, they invariably died without laying eggs. T. vicina was observed to feed upon man when encountered in the jungle although a slow beginner. In the Laboratory a larva of T. vicina was observed feeding upon a larva of A. (S) albopictus.
40. Laboratory bred specimens of Aedes togoi, a seashore pest, were found to breed in captivity without a blood meal, being only fed upon raisins; another generation was obtained from these. This mosquito has been experimentally infected during the year with micro-filariae (W. bancrofti).
41. A mosquito which closely resembles C. vishnui but whose larvae differ in some respects from those of C. vishnui, is being investigated.
42. Specimens of A. (S) aegypti larvae and imagines, were received from Dr. Scharff, this mosquito is rarely met with in the Colony, but one was captured by an Inspector on a mosquito net in a hut behind the village of Aberdeen. The captive laid eggs from which larvae and adults were obtained.
43. A. (S) albopictus are often found breeding in anti-formicaries, jugs, basins, etc. inside houses; in discarded bottles, tins, jars, etc. in the compounds of houses and under such circumstances cause a considerable nuisance. They also breed in tree holes. Near the quarters occupied by the Malariologist, breeding was taking place in tree holes in secondary jungle some 50 yards from the house. During the hot weather this mosquito could be caught in abundance in the jungle yet so few ever came into the house that it was not thought worth while to take any action especially as these tree holes were being kept under observation to ascertain what other species not forgetting Anophelines, might be found in them.
44. C. fatigans, 1042 in number, were dissected for Avian malaria and for filarial infections. These mosquitoes were obtained from village huts and contractor's matsheds whilst searching for Anopheline mosquitoes. No infections were found.
45. Specimens of larvae and adults of various mosquitoes were given to Dr. S. Hu (Lester Institute, Shanghai) on the occasion of his visit to the Laboratory, also living larvae of C. fatigans which he required for experimental purposes.
