31. A. aitkeni var. bengalensis. The larvae were met with in shady pools in hill streams but no adults were obtained in catches. This mosquito has plain wings like a Culicine, specimens hatched out from larvae have been observed to adopt the Culicine attitude whilst resting.
32. A. tessellatus. No larvae of this species were collected during the year but a few imagines were obtained from huts at Little Hong Kong, and many more in catches done there at night in pigsties. One of the mosquitoes obtained from the huts was found infected with oocysts.
33. A. vagus.
Larvae were collected from small grassy muddy pools and from pools in rice stubble in the course of surveys done on the mainland. Adults were captured in the catches done at the Dairy Farm cowbyres, Pokfulam, and in cowbyres on the mainland.
34. A number of larvae of A. karwari and A. splendidus were collected from fallow rice fields in the rainy season. It has been found that the lateral hairs on the 5th and 6th segments are of great help in distinguishing the larvae of A. karwari from those of A. splendidus and of A. maculatus. Few adults of either species were captured.
35. Specimens of larvae and imagines were received from Dr. L. C. Feng, Peiping Union Medical College, specimens of larvae from Mr. F. E. Baisas, Bureau of Health, Manila, of imagines from Dr. I. M. Puri, Malaria Survey of India, Kassauli. Specimens of imagines were sent to Dr. Feng, of imagines, larvae and eggs to Mr. Baisas, of imagines to Dr. G. A. Rose, Hangchow, of imagines to Professor Davis, Hong Kong University, of imagines to Dr. Scharff, Singapore.
36. Blood from the midguts of mosquitoes captured in various places were sent to M. Toumanoff, Chef du Laboratoire d'Entomologie de l'Institut Pasteur de Saigon for favour of examination. A full report has not yet been received but such information as is available is furnished in Table VIII.
Culicines.
37. Larvae of C. gelidus were met with and identified, this mosquito has not previously been recorded for Hong Kong.
38. Two new species of Ficalbia were submitted to Dr. Edwards, British Museum, one he considers to be a new species, the other to be closely related to F. chamberlaini.
