PACIFIC SCIENCE, VoL V, October, 1951 
1946c). Northeast New Guinea: Draeger Har- 
bor, Cape Cretin (Edwards, 1926); Bulwa 
(Taylor, 1934); Lae (Marks, 1947^). Papua: 
Wasima Island, Yule Island (Hill, 1925); 
Lalapipi, Dobodura (Marks, 1947^); Milne 
Bay (Marks, l9Ala\ Author). 
HABITAT: Wallacei has been recorded from 
leaf axils of banana, taro, pineapple, and Fan- 
danus^ and from fallen palm leaves (Taylor, 
1934; King and Hoogstraal, 1946c; Marks, 
1947^). 
My three collections were all from leaf 
axils — two from pineapple and one from 
Pandanus— in clear, shaded water. Wallacei 
occurred once in a pure collection, once with 
U. papua, and once with T. himacuUpes . 
Aedes (Skusea) dasyorrhus 
King and Hoogstraal 
Aedes {Skusea) dasyorrhus King and Hoog- 
straal, 1946, Ent. Soc. Wash. Proc. 48 (4): 
100. Type locality: Cape Tjeweri, Jatufa 
Bay, Hollandia, Dutch New Guinea. 
DISTRIBUTION: Dutch New Guinea: Hol- 
landia, Biak (King and Hoogstraal, 1946c). 
Papua: Milne Bay (Author). 
HABITAT: Dasyorrhus has been reported by 
King and Hoogstraal (1946c) from cans at 
the edge of a mangrove swamp, possibly with 
partially salt water, and from a metal con- 
tainer. 
Our five collections were all from holes in 
low, horizontally placed tree trunks extend- 
ing out over the waters of Milne Bay and 
obviously receiving salt water spray. Three 
salinity readings showed 30, 50, and 65 per 
cent of sea water. A. dasyorrhus and C. sitiens 
were the only species collected from this very 
unusual habitat. Dasyorrhus occurred pri- 
marily in exposed, clear water with sparse 
amounts of algae, and always in pure collec- 
tions. 
Aedes (Stegomyia) albolineatus 
(Theobald) 
Scuteomyia alholineata Theobald, 1904, En-

landia (Knight and Rozeboom, 1946; King 
and Hoogstraal, 1946^^, c); Toem (Knight 
and Rozeboom, 1946); Padaido Islands, Am- 
sterdam Island (Author). Northeast New 
Guinea: Finschhafen, Saidor (Knight and 
Rozeboom, 1946; Author); Morobe (Au- 
thor). Papua: Dobodura (Knight and Roze- 
boom, 1946) ; Milne Bay (Knight and Roze-

Albolineatus and A. scutellaris were the only 
species present in every area studied. 
Taylor (1934), Lee (1944^), and Knight and 
Rozeboom (1946) record albolineatus from 
tree holes, coconut shells, artificial containers, 
leaf axils, fallen leaves, and rock pools. My 
habitat indices are in agreement with the 
literature and demonstrate the high affinity of 
albolineatus for tree holes. 
Albolineatus occurred almost equally in pure 
(44 per cent) and in mixed (56 per cent) col- 
lections. Percentages of associated species 
were: A. scutellaris, 11; T. bimaculipes, 7; A.
