Paddle: Elongate oval shaped, length nearly 
one-third greater than width; margin rounded, 
smooth; midrib strong, reaching apex, dividing 
the paddle almost equally although the lateral 
face is slightly wider than the medial face; ter-

cessory seta small, simple. 
Specimens examined. — The pupal exuviae 
of nine males and eleven females from Gama- 
dodo, WagaWaga, and Hilimoi, Milne Bay, 
Papua, and Draeger Harbor, Northeast New 
Guinea. 
Subgenus Acallyntrum Stone and Penn 
Diagnosis. — The pupae of the two New 
Guinean species of Acallyntrum are distinct 
from those of all other Culex of the island in 
the absence of both the terminal and accessory 
paddle setae. 
Key to Species of Culex ( Acallyntrum ) 
Lateral margins of paddles finely serrate; only 
the larger setae of segments III to VII plu- 
mose, all other setae non-plumose (Fig. 
54) C. bicki 
Lateral margins of paddles smoothly rounded, 
not serrate; nearly all of the dorsal abdom- 
inal setae finely plumose (Fig. 55) 
C. binigrolineatus 
Culex (Acallyntrum) bicki Stone and Penn 
1947

This pupa was described and figured by Stone 
and Penn (1947: 89). The following descrip- 
tion is taken from this paper with additional 
unpublished notes on the species.

nent, plumose, three- or four-branched.

simple; 12 usually three -branched. 
Abdomen. — Segment I: H small, simple; K 
long, simple; L small, four-forked near middle; 
M small, six-forked near base; S long, simple; T 
long, two-branched; U small, simple. 
Segment II: A small, simple spine; B medium, 
simple; C small, six- or seven-branched; c' small, 
simple on this and all following segments; 1 
medium, two-branched; 2 long, simple; 3 small, 
simple; 4 small, three-forked near base; 5 mi- 
nute, simple on this and all following segments. 
Segment III: A small, simple spine; B long, 
simple; C medium, three-branched; 1 medium, 
simple; 2 small, two-branched; 3 represented 
only by its socket on this and segments IV and
