Mosquito Larvae of New Guinea — Bick 
403 
stated that it has been found in relatively 
fresh water in tins, in old coconuts, and in 
tree holes. I did not collect it from tree holes 
or from leaf axils. Argenteiventris occurred to 
an approximately equal degree in pure (43 
per cent) and in mixed collections. Associates 
were: A. scutellaris (19 per cent), others (38 
per cent).

Taylor (1934) found bimaculipes in cut ends 
of bamboo, and Lee (1946) found it in hollow 
logs, tree holes, artificial containers, and 
coconut shells. In our surveys it occurred 
frequently (84 per cent) in mixed collections. 
Percentages of associated species were: A. 
alboUneatus, 19; scutellaris^ 14; U. nigerrima, 
11; Poxorhynchites spp., 7; A. notoscriptus, 7; 
Arm. milnensis, 5; U. argyrotarsis, 5; others, 16.

1934, Bui. Ent. Res. 25: 508. 
Lee (1946) stated that two specimens from 
Oro Bay and several from Biak (in the Uni- 
versity of Queensland collection) differ from 
T. brevipalpis in a few details. He believes that 
it would be wise to wait for more adequate 
material before describing this "probably new 
form." Miss Elizabeth Marks, University of 
Queensland, in a personal communication to 
me, states: "The specimens of T. brevipalpis? 
from Biak mentioned by Lee are your series."
