(65 per cent) in mixed collections. Percent- 
ages of associates were: C pullus, 18; An. 
farauti, 15; C. halifaxi, 12; C. annulirostris, 6; 
C. squamosus, 5; others, 9. 
Toxorhynchites spp. 
In our series of reared individuals, only 
adult females are represented, so that accurate 
specific determinations are impossible. How- 
ever, because many collections of larvae were 
obtained, it is considered worth while to give 
my distribution and habitat data for the genus 
even though possibly more than one species 
is represented. 
DISTRIBUTION: The genus is represented in 
my records from Padaido Islands, Saidor, 
Finschhafen, and Milne Bay.

Newkirk (1947) found Toxorhynchites splen- 
dens commonly in rain barrels and once in a 
latrine pit at Milne Bay. My specimens were 
found most abundantly in artificial con- 
tainers. They occurred to an approximately 
equal extent in pure (52 per cent) and in 
mixed collections. Percentages of associates 
were: A. scntellaris^ 6; T. himaculipes, 5; A. 
albolineatus, 5; Arm. hreinli, 5; C. fragilis, 5; 
others, 22. 
Tripteroides (Rachisoura) confusa Lee 
Tripteroides (Rachisoura) confusa Lee, 1946, 
Linn. Soc. N. S. Wales, Proc. 70: 251. Type 
locality: Milne Bay, Papua. 
"Known with certainty only from the type 
locality but probably quite widely distributed. 
This is very likely the species which has 
usually been called T. atra, owing to the para- 
type of that name seen by Edwards not being 
conspecific with the type." (Lee, 1946.) 
Lee (1946) recorded T. confusa from tins 
and coconut shells, in association with T. 
himaculipes. My single pure collection from 
Milne Bay was from a taro leaf axil in clear, 
temporary, shaded water.

Polylepidomyia argenteiventris Theobald, 1905,

DISTRIBUTION: Dutch New Guinea: Assike, 
Merauke, Tanahmerah (Bonne- Wepster,

Guinea: Tsili Tsili, Nadzab (Lee, 1946); Lae 
(Lee, 1946; Mackerras, 1946); Finschhafen 
(Author). Papua: Paimumu River (Theobald, 
1905); Dobodura (Lee, 1946); Milne Bay
