The genus Bironella occurred mostly (68 
per cent) in pure collections. Percentages of 
associates were: U. argyrotarsis, 11; C. frauda- 
trix, 9; C. pullus^ 4; others, 8.

Anopheles papuae soesiloi Strickland (Bei Soesilo 
and van Slooten, 1931) Swellengrebel and 
Rodenwaldt (1932: 62). 
DISTRIBUTION: Dutch New Guinea: Boemi- 
Bezirk, Hollandia (Swellengrebel and Roden- 
waldt, 1932). Lee and Woodhill record it as 
questionable from Boemi and Hollandia. 
Papua: Milne Bay (Lee and Woodhill, 1944; 
Author) . 
HABITAT: Lee and Woodhill (1944) record 
it from a swampy creek. Both of my collec- 
tions were from pot holes in creeks, in fresh, 
temporary, clear, shaded water at a pYi of 5. 
It was found once in a pure collection and 
once with U. argyrotarsis, C. papuensis, and B. 
travestitus.

DISTRIBUTION: Dutch New Guinea: Tahah-

Papua: Cape Endaiadere (Lee and Woodhill, 
1944); Milne Bay (Lee and Woodhill, 1944; 
Author) . 
HABITAT: Lee and Woodhill record it in 
partially shaded swamps and in pools in a 
sago swamp. My single collection was from 
a temporary, shaded pot hole in a creek, with 
a sparse amount of debris, at a pW of 5, and 
in association with U. argyrotarsis, C. fragilis, 
and B. soesiloi sensu Swellengrebel and Roden- 
waldt. 
Anopheles (Anopheles) bancrofti 
pseudobarbirostris Ludlow 
Anopheles pseudobarbirostris Ludlow, 1902, 
N. Y. Ent. Soc. Jour. 10: 129. 
DISTRIBUTION: Northeast New Guinea: 
Sepik River, Madang (Lee and Woodhill, 
1944); Saidor (Author). Papua: Cape Endai- 
dere, Oro Bay, Terapo, Lalapipi, Dobodura 
(Lee and Woodhill, 1944); Milne Bay (Lee 
and Woodhill, 1944). 
HABITAT: Lee and Woodhill state that it is 
found only in the jungle, usually in clear 
pools with abundant aquatic vegetation, in 
dense shade, or in places which receive direct 
sunlight only during the middle of the day. 
In our survey, pseudobarbirostris was present 
in three collections from ponds with vegeta- 
tion. Its scarcity may be due to the fact that 
its chief habitat seems to be rather large, 
permanent, well-vegetated bodies of clear, 
shaded water which were almost entirely ab-
