ther two- to four-branched; a' medium, simple 
or rarely two-forked near apex. 
Paddle: Roundly oval, length not greatly ex- 
ceeding width; margin very finely toothed api- 
cally, not obvious without high-power magnifi- 
cation; midrib strong, dividing the paddle almost 
equally, the medial face only slightly wider than 
the lateral face; terminal seta strong, simple. 
Specimens examined. — The pupal exuviae 
of twelve males and four females from Hilimoi, 
Milne Bay, Papua. 
Subgenus MACLEAYA Theobald 
A certain diagnosis of Macleaya is not pos- 
sible at present since the single species assigned 
to this subgenus has not been completely de- 
scribed in the pupal stage.

Pupa undescribed, but Hill (1925: 72) in- 
cluded figures of the trumpet, posterior margin 
of segment VIII, and the paddles of specimens 
from Queensland, Australia. These have been 
redrawn and are included here. 
If Hill’s figures are correct, the elongate na- 
ture of the paddles ( twice as long as wide ) and 
the coarsely serrate apex should prove to be of 
diagnostic value for the species as well as the 
subgenus among the known Aedes of New 
Guinea. 
Subgenus PSEUDOSKUSEA Theobald 
The pupa of none of the three New Guinean 
species belonging here has been described. 
Subgenus Skusea Theobald 
Diagnosis. — Only one species of Skusea has 
been recorded from New Guinea and only three 
or four from the whole Australasian Region, but 
these are distinct in the pupal stage from other 
Aedes in possessing wide paddles with a fringe 
of long fine hairs almost all around the margin, 
and in having the dorsal seta (8) of cephalo- 
thorax placed between the trumpets.

Cephalothorax. — Postocular: 1 small, two- 
or three-forked; 2 very long, stout, two- or 
three-forked; 3 long, two-forked or simple. 
Anterothoracic: 4 long, stout, three- or four- 
forked; 5 small, two- to four-forked, rarely 
simple; 6 small, simple; 7 medium, simple or 
occasionally two-forked. 
Dorsal: 8 medium, about one-half length of 
trumpet, simple or two- to three-forked. 
Supra-alar: 9 long, nearly equal to trumpet, two- 
forked or rarely simple. 
Metanotum: 10 small, simple or two-forked, 
rarely three-forked; 11 long, simple; 12 medium, 
three- or four-forked, rarely simple or two- 
forked. 
Trumpet: Small, length a little more than three 
times the greatest diameter of meatus; pinna a 
little more than one-fourth of total length; uni- 
formly lightly pigmented. 
Abdomen. — Segment I: h medium, simple; 
K long, simple; L small, two- or three-forked or 
simple; M medium, four- or five-forked, occa- 
sionally three-forked; S long, simply T long, 
two- or three-forked; U small, simple. 
Segment II: A small, simple spine; B long, 
simple; C long, four- or five-forked near basal 
fourth, or rarely three-forked; c' medium, 
simple; 1 medium, three- or four-forked near 
base; 2 long, two- or three-forked or occasion- 
ally simple; 3 small, two- to four-forked near 
middle; 4 small, two- to four-forked near middle. 
Segment HI: A small, simple spine; B long, 
simple or rarely two-forked at apex; C small, 
simple or two-forked; c' small, simple on this
