Mosquitoes of New Guinea — PENN 
67 
Segment VII: A long, stout, black, plumose, very 
similar to B-VI, three- or four-branched, rarely 
two-branched or forked; B small, various, two- 
to six-forked near base; c very small, simple or 
two-forked near base; 1 small, two- or three- 
forked near base, rarely simple; 2 very small, 
two-forked near base or simple; 4 small, usually 
three-forked near base, occasionally simple or 
two- to four-forked. 
Segment VIII: A very long, large, conspicuous, 
black, plumose tuft, range from six- to eleven- 
branched, usually nine-branched; a' small, two- 
or three-branched, occasionally simple or four- 
branched. 
Fig. 47. Armigeres milnensis: dorsal aspect of right 
half of abdomen of female from Hilimoi, Papua. 
Paddle: Roundly oval, slightly longer than wide; 
with a fringe of long fine hairs on the margin 
starting at the apical one-third laterally and ex- 
tending to the apical one-half medially; midrib 
stronger than in breinli, dividing the paddle 
almost equally into halves; with an irregular 
broken line of black pigment across basal part 
of paddle; terminal seta medium, strong, simple. 
Specimens examined. — The pupal exuviae 
of two males and eight females from Hilimoi, 
Milne Bay, Papua, and Draeger Harbor, North- 
east New Guinea. 
Armigeres lacuum Edwards 1922 
Pupa undescribed, but Hill (1925: 70) in- 
cluded figures of the trumpets, terminal abdom- 
inal segments, and paddles. These figures are 
not included here since they lack the detail 
necessary to bring out features which would 
distinguish A. lacuum from the other species 
in New Guinea. 
Genus CULEX Linnaeus 
Diagnosis. — The pupae of Culex can usually 
be distinguished from those of other genera 
by the presence of an accessory seta situated 
beside the terminal seta at the tip of the midrib 
of the paddle, and by the presence of a small 
spine-like seta on the postero-lateral corner of 
segment IX. These features are both somewhat 
difficult to appreciate on all specimens and are 
not absolutely diagnostic because the New 
Guinean species of the subgenus Acallyntrum- 
have neither terminal nor accessory paddle setae, 
and the accessory seta is absent from C. squamo- 
sus; seta v-IX is extremely difficult to see on 
most species and apparently is not always pres- 
ent on C. sitiens. Two other features charac- 
terize the large majority of Culex pupae, though 
again there are exceptions; the trumpets have a 
dark tracheoid area close to the base; and setae 
A- VII and A- VIII, which usually form well- 
marked plumose tufts, are placed well before 
the corners of the segments. The dorsal seta 
(8) of cephalothorax is usually placed well 
behind the bases of the trumpets.
