four-forked near middle; 3 represented only by 
its socket; 4 medium, simple or rarely two- 
forked. 
Segment VI: A small, simple spine; B very long, 
plumose, two- or three-branched; C long, plu- 
mose, two- or three-branched; 1 medium, simple 
or occasionally two-forked; 2 medium, two- 
forked near middle or occasionally four-forked; 
3 absent; 4 long, simple or rarely two-forked. 
Segment VU: A long, plumose, four- to eight- 
branched, most frequently seven-branched; B 
medium, simple; C long, simple; 1 small, two- 
forked or rarely simple; 2 medium, simple; 4 
medium, simple. 
Segment VIII: A long, plumose, nine- to thir- 
teen-branched, most frequently eleven-branched; 
A' long, simple. 
Segment IX: v minute, stout, simple. 
Paddle: Rounded, slightly longer than greatest 
width, apex with a notch at end of midrib; 
margin smooth; midrib dividing paddle un- 
equally, lateral face a little wider than medial 
face; terminal seta very small, simple; accessory 
seta a little longer, simple. 
Specimens examined. — The pupal exuviae 
of three males and seven females from Gama- 
dodo, WagaWaga, and Hilimoi, Milne Bay, 
Papua. 
Subgenus Neoculex Dyar 
None of the four species recorded from New 
Guinea has been seen in the pupal stage, and 
so few pupae of Neoculex have been described 
that it is impossible to present a subgeneric 
diagnosis at the present time. 
Subgenus MOCHTHOGENES Edwards 
Diagnosis. — Only two of the species of this 
subgenus have been described in the pupal 
stage. For these Edwards (1941: 412) notes 
the following features: All cephalothoracic setae 
inconspicuous; seta 11 of metanotum double; 
setae K and S about equally long and simple; 
T also simple but shorter; paddle seta somewhat 
stronger than usual, and accessory seta present. 
The pupa of the single species recorded from 
New Guinea is unknown. 
Subgenus Lophoceraomyia Theobald 
Diagnosis. — The pupae of the two species 
recorded from New Guinea agree in the follow- 
ing features: Trumpets fairly long, with well- 
developed tracheoid portion. Seta C with more 
than six branches on segments II and III; seta 2 
on segment II long and simple, the most con- 
spicuous seta on the segment; setae A-VII and 
A- VIII, the only plumose tufts on the abdomen. 
Key to Species of Culex ( Lophoceraomyia ) 
Seta B on segments IV through VII less than 
the length of the following segment; seta 
1 on segments III through VI a branched 
tuft (Fig. 49) ... C. fraudatrix 
Seta B on segments IV through VI much 
longer than the following segment; seta 1 
on segments III through VI usually simple, 
never more than two-branched (Fig- 50)

Cephalothorax. — Postocular: 1 small, 
three- to six-forked; 2 medium, two- to four- 
forked; 3 medium, three- or four-forked, rarely 
five-forked. 
Anterothoracic: 4 medium, three- or four- 
forked, rarely five-forked; 5 medium, simple or 
two-forked, rarely three-forked; 6 small, simple 
or two-forked, rarely three-forked; 7 medium, 
two-forked or occasionally three-forked. 
Dorsal: 8 medium, one-half length of trumpet, 
two-forked. 
Supra-alar : 9 small, simple or two-forked, rarely 
three-forked. 
Metanotum: 10 medium, two-forked or rarely 
simple; 11 medium, two-forked or rarely simple; 
12 medium, two- to four-forked. 
Trumpet: Long, narrow, length about twelve 
times the greatest diameter of the meatus; tra- 
cheoid area fairly well developed, dark; pinna 
short, less than one-eighth of the total length 
of the trumpet. 
Abdomen. — Segment I: h small, simple; K 
long, two-branched; L very small, two-forked;
