PACIFIC SCIENCE, Vol. V, October, 1951 
sent in the study areas. It was collected with 
An. punctulatus, An. farauti^ U. argyrotarsis, 
and C. fraudatrix. 
Anopheles (Myzomyia) farauti Laveran 
Anopheles farauti 1902, Soc. de Biol. 
[Paris] Compt. Rend. 54: 908. 
Anopheles punctulatus molluccensis Sw. and Sw. 
de Graaf. Lee and Woodhill (1944: 140). 
Anopheles punctulatus farauti Laveran. Macker- 
ras and Aberdeen (1946: 770); Mackerras 
(1947: 1-8). 
In 1945 Owen described An. koliensis from 
the Solomons. This form is intermediate be- 
tween An. punctulatus and farauti. Certain 
earlier workers have long recognized "inter- 
mediates” which are clearly koliensis; others 
make no distinction. Obviously, in the latter 
cases the material cannot be safely referred to 
any of the three species (or subspecies) of the 
complex. I have limited the literature in the 
following discussions to those who, ap- 
parently, were clearly aware of koliensis or at 
least of intermediate forms. I believe that 
most of my material is farauti but, since all 
of the collections were made without knowl- 
edge of koliensis and since only a relatively few 
individuals were available for subsequent 
careful checking, certainty is impossible.

In the New Hebrides and Solomon Islands, 
Belkin et al. (1945), Perry (1946), and Daggy 
(1945) found that the breeding places con- 
sisted primarily of relatively large collections 
of surface water, but that after heavy rains a 
great variety of small temporary water collec- 
tions was used. In New Guinea, Lee and 
Woodhill (1944) considered sago swamps, 
backwaters of creeks, and grassy pools and 
puddles as common habitats. Horsfall and 
Porter (1947) also give natural pools and
