PACIFIC SCIENCE, Vol. V, October, 1951 
detailed studies of the biology of A. scutellaris 
were published by Mackerras (1946), Forbes 
and Horsfall (1947), and Penn (1947^). All 
detailed studies have demonstrated that arti- 
ficial containers are the primary habitat of 
this important dengue vector. 
. Scutellaris occurred mostly (73 per cent) in 
pure collections. The main associate was A. 
alholineatus (6 per cent), but there was an 
extremely long list of 20 other associates 
which has been given by Penn (1947^).

Vexans was widely distributed but an un- 
common species. The above records are the 
first for Northeast New Guinea. My limited 
data and records of Bonne-Wepster and Brug 
(1937, 1939) and Lee (1944<^) show that it is 
exclusively a surface breeder. However, 
Bonne-Wepster and Brug (1939) found it in 
fresh, brackish, and salt water, whereas my 
specimens were entirely from fresh water. It 
occurred primarily (75 per cent) in mixed col- 
lections. Percentages of associates were: An. 
punctulatus, 25; C. pullus, 17; others, 33. 
Aedes (Aedes) funereus (Theobald) 
Skusea funerea Theobald, 1903, Mon. Cul. 3:

distribution: Dutch New Guinea: Wamal, 
Tanahmerah, Merauke, Assike (Bonne-Wep- 
ster, 1938); Hollandia (Toffaleti and King, 
1947 ). Northeast New Guinea: Saidor, 
Finschhafen (Author). Papua: Mekeo Dis- 
trict (Taylor, 1914^?; Edwards, 1924); Milne 
Bay (King and Hoogstraal, 1947; Author).

These records from Saidor and Finschhafen 
are the first from Northeast New Guinea. 
Hill ( 1922 ) recorded 
it in an algae- and grass- 
covered seepage, in fresh water pools, and in 
salt puddles in mangrove swamps. Lee 
( 1944 ^) lists it from fresh water swamps. In 
my collections also, funereus occurred in sur- 
face water only, and 
was never found in salt 
or brackish water. 
It occurred mostly in
