New Mosquito from Fiji — Laird

medially directed setae of this type (location 
indicated diagramatically in Fig. 2 B); an 
irregular double row of elongate straight or 
slightly curved setae extends down the sternal 
face of the coxite, whilst on the inner sternal 
edge, and at about one-quarter of the length 
of the coxite from its base, a bent, slender 
and inconspicuous specialized seta arises from 
a prominent tubercle (Figs. 1, 4 A); no sub- 
terminal setae are borne by the curved and 
slender style, which is about twice the length 
of its terminal appendage (Fig. 1); the ap- 
pendage of the harpago is sharply pointed 
and broadly triangular (Fig. 3), and the para- 
proct has a single tooth. 
LARVA: Very pale, the head and siphon 
lightly chitinized and the thorax and abdo- 
men bearing stellate setae. Antenna non- 
spiculate, the tuft a single simple seta of 
rather more than half the length of the an- 
tenna and inserted at about the apical one- 
third; a long and sinuous subterminal seta 
ventrally (Fig. 5). Clypeal spine double. Head 
seta A stellate, posterior to B and d, and 
having from 9 to 13 frayed branches with 
forked tips, the longest branch being half as 
long again as the antenna; d and B two- or 
three-branched and simple, d rather shorter 
than B which exceeds the antenna in length; 
B originating in front of d, and these two 
setae a little closer to one another than B is 
to A; C an elongate simple seta originating 
behind the level of the base of the antenna 
and more or less in line with B; e with two 
branches and f three- or four-branched, the 
branches of these setae being simple and 
about as long as the clypeal spines (Fig. 5). 
Mentum (Fig. 7) with a stout medial tooth 
and eight smaller lateral teeth, the most basal 
of which is minute and widely separated from 
its nearest neighbour. 
Abdominal segments I to VI each bearing 
a pair of long and plumose lateral setae, those 
of segment I being 8- to 10-branched, those 
of II 7- to 9-branched and those of III to VI 
2-branched. 
The lateral comb is a broadly triangular 
patch of from 70 to 80 scales in four irregular 
rows (Fig. 6), those of the distal row number- 
ing from 14 to 16 and measuring some 65/x 
in length; these scales (Fig. 10, A), which 
are spatulate and fringed both laterally and 
apically, altogether lack lateral spines; the 
scales of the other rows are similar but shorter; 
two or three uneven lines of minute setae are 
located in front of the proximal row (Fig. 6). 
The first and fifth pentad hairs are stellate, 
the frayed branches ranging from 8 to 12 in 
number and having forked tips; both the sec- 
ond and fourth pentad hairs are single and 
simple, while the third is four-branched and 
plumose (Fig. 6). The siphonal index is about 
2.5 to 3.0, the siphon itself being bare except 
for sparse spicules basally and bordering the 
pecten, and an apico-dorsal patch (Fig. 6). 
There are from 8 to 11 pecten spines, the
