Culex (Acallyntrum) bicki Stone and Penn 
Culex bicki Stone and Penn, 1947, Wash. 
Acad. Sci. Jour. 37: 89. Type locality: 
Toem, Dutch New Guinea. 
Culex {Acallyntrum) bicki Stone and Penn 
(1948: 109). 
DISTRIBUTION: Dutch New Guinea: Toem 
(Stone and Penn, 1947). Papua: Milne Bay 
(Stone and Penn, 1947; Author). 
HABITAT: My single collection of bicki was 
a pure collection from a clear, shsided Pan- 
danus leaf axil with abundant debris. Stone 
and Penn (1947) recorded it from sago and 
taro leaf axils.

Specific locality records for New Guinea 
are few, the typical reference being "along all 
coasts of the Australasian Region." No doubt 
most authors have considered it too common 
to merit specific records. My collections from 
Milne Bay are apparently the first records 
from Papua. 
Bonne- Wepster and Brug (1937), Taylor 
( 1943 ), and Lee (1944^^) report annulirostris- 
mostly from fresh surface water but also from 
brackish habitats. In my collections it was 
found almost entirely in surface water (pri- 
marily puddles, 75 per cent) but never in 
brackish situations. The puddles commonly 
utilized were usually old, large, rather deep, 
and well vegetated in contrast with the small, 
shallow, muddy, and non-vegetated puddles 
so often utilized by C. pullus, C. halifaxi, and 
An. punctulatus. Furthermore, in contrast with 
the above species, annulirostris was found al- 
most entirely (96 per cent) in shade, the 
highest per cent recorded for any surface 
water species. 
Annulirostris occurred mostly (74 per cent) 
in mixed collections. Percentages of asso- 
ciates were: C. pullus, 16; An. punctulatus., 16; 
An. far auti, 16; C. halifaxi, 13; others, 13.
