Argyrotarsis was quite common in my col- 
lections but apparently it has not previously 
been reported from either Papua or Northeast 
New Guinea. 
It has been recorded by Taylor (1934) and 
by King and Hoogstraal (1946/) from ground 
pools. Ninety per cent of my collections were 
from surface water, but 10 per cent were from 
artificial containers. Argyrotarsis occurred 
mostly (71 per cent) in mixed collections. 
Percentages of associates were: C. pullus, 20; 
C. halifaxi, 13; An. farauti, 10; C fraudatrix, 
7; Bironella spp., 5; others, 16.

Nigerrima has been recorded from fallen 
leaves, fallen coconut bracts, coconut shells, 
and tree holes (Taylor, 1934; Lee, 1944^; 
King and Hoogstraal, 1946c). However, my 
indices show that spathes and leaves were 
seldom utilized and that tree holes were never 
used. Artificial containers and coconut shells 
were the more important habitats. This 
species occurred to an approximately equal 
degree in pure (52 per cent) and mixed col- 
lections. Percentages of associates were: 
Arm. hreinli, 9; T. himaculipes, 9', A. alhoUne- 
atus, 7; A. scutellaris, 6; Toxorhynchites spp., 
6; C. fragilis, 6; others, 5.
