PACIFIC SCIENCE, Vol. XII, July, 1958 
pay study along these lines is the genus Theo- 
baldia , expecially as the Australian species 
have been recently revised (Dobrotworsky, 
1954). 
A description of the new species follows. 
Culex ( Culex ) iyengari n. sp. 
The description which follows is based on 
holotype male from We, Lifu, Loyalty Islands, 
7:x:1955, bred out by one of us (J.R.) from a 
native canoe, allotype female and 4 male and 1 
female paratypes with data as for the holo- 
type; 12 male and 4 female paratypes with 
similar data but bred from a barrel and a tank 
on ll:x:1955; 5 male paratypes from Baie de 
la Corbeille, lie des Pins, New Caledonia, bred 
out by J.R. from native canoe on I4:xii : 1955 ; 
1 male and 1 female paratype from Poncrihuen, 
New Caledonia, bred out from rainwater in a 
metal cistern by M. O. T. Iyengar in ii : 1956; 
2 whole larvae from the same batch as these 
last 2 adults and a large number of whole 
larvae from We, Lifu, 8:x:1955 (native canoe) 
and 9:x:1955 (old barrel and tank), Ba River, 
near Houailou, 9 :vi : 1955 (rock pool in stream 
bed), Hnanemuhaetra, Lifu, 9:x:1955 (hole in 
coconut trunk), Joj, Lifu, 9:x:1955 (rock pool 
in coral), Kedany, Lifu (well 38 m. deep) and 
Kuto, lie des Pins, I4:xii: 1955 (all collect. J. 
R.). The larvae from We (9:x:1955) were asso- 
ciated with larvae of Culex pipiens fatigans 
(Wied.), Aedes notoscriptus Skuse and Trip- 
teroides melanesiensis Belkin, those from Hnane- 
muhaetra and Joj with larvae of Ae. notoscriptus 
and T. melanesiensis , and those from Ba River 
with larvae of Culex cheesmanae Mattingly and 
Marks and Culex pipiens australicus Dobr. and 
Dr. The holotype and allotype and the bulk of 
the paratypes will be deposited in the British 
Museum (Natural History) but some para- 
types will be sent to the U. S. National Mu- 
seum, the Department of Entomology, Uni- 
versity of Brisbane and the Institut d’Enseig- 
nements et des Recherches Tropicales, Bondy, 
France. 
adult male: Palps upturned at tip, exceed- 
ing the proboscis by about the length of the 
terminal segment, the hairs on the under sur- 
face rather short (Fig. 3a), very much more so 
than in C. pervigilans (Fig. 3c) or C. pipiens 
(Fig. 3d). A narrow ventral line of broad, flat, 
pale scales present on the sub apical segment 
and the extreme base of the apical segment. A 
small subapical pale patch below on shaft. 
Tori dark brown with a few small dark scales. 
Vertex with numerous creamy, narrow, curved, 
decumbent scales and pale- to dark-brown 
upright forked scales. Proboscis mainly dark 
but pale below to a variable extent about the 
middle. Central area of mesonotum covered 
with narrow, curved, bronze-coloured scales, 
extreme edges with similar scales, intervening 
lateral areas with dark-brown scales which are 
separated into anterior and posterior patches 
by an intervening whitish spot halfway be- 
tween the wing root and the scutal angle. 
This spot produced backwards to fuse with 
an indefinite area of whitish scales round the 
prescutellar bare space. 
All scutellar scales whitish and very narrow. 
Some broader, creamy, curved scales on an- 
terior border of mesonotum. Anterior and 
posterior pronota with narrow, curved, whit- 
ish scales. A few scales apparently present on 
the postspiracular area and the knob of the 
sternopleura but these areas rubbed. The usual 
upper and lower sternopleural and the mese- 
pimeral scale patch well developed. A single 
well- developed lower mesepimeral bristle pres- 
ent in the usual position. Wings dark. Alula 
with a fringe of narrow scales. Squama with a 
strongly developed fringe of slender hairs. 
Anterior fork cell a little less than two and a 
half times the length of its stem. Haltere with 
stem pale and knob only slightly darkened. 
Legs mainly dark. Hind femur with a narrow, 
incomplete, dark dorsal line which does not 
reach base and which expands onto the an- 
terior and posterior surfaces only at extreme 
tip. Hind tibia with a small pale spot at tip 
scarcely as long as broad. Fore tibial claw ab- 
sent. First abdominal tergite wholly or largely 
dark, remainder with pale basal bands which 
are shallower on the more posterior segments
