)lour according to the direction of the light from blue-black to dark olive- 
rown. Basal joint of antenna black, scaled above, remaining joints black, 
■ith a dense tuft of scales on the inner side of the second joint; verticillate 
airs, black. Palpi, entirely black scaled. The palpi are longer, than 
1 Barbirostris and not so heavily scaled at the base. Some specimens 
xceptionally shew a tendency to pale bands at the junction of third and 
ourth and fourth and fifth joints. 
Thorax .—Prothoracic lobes black, with a tuft of dark brown scales on 
le apex and some golden-brown bristles beneath these. Mesonotum, dark 
urple clad with pale golden hairs. Scutellum, brown with golden hairs, 
heurse, blackish-brown. Wings, clad mainly with dark brown scales 
Vhich are mingled with pale golden scales on some of the veins. There is 
small pale spot on the costa at its junction with the subcosta, and another 
.t the apex which passes on to the upper branch of the second. Lateral 
vin^s scales fusiform, broad, slightly broader than the scales on t e 
vin? of Barbirostris, fringe scales black, and there is no pale spot opposite 
ower branch of fifth vein and no pale fringe spot at the apex of wing. 
2 oxse, blackish-brown with pale hairs only. Legs, ochraceous with black 
scales and narrow pale bands involving both sides of the joint on the 
netatarsal and first two tarsal joints of fore and mid legs. On the hind 
e^s there is a narrow pale band at the apex of tibia and metatarsus a 
Droad band at the apex of the first tarsal joint and a broad creamy band 
it base and apex of second tarsal joint and also the third tarsal joint, 
while the fourth joint is creamy at the base and black at the apex. 
Abdomen.— Black, with numerous pale ochraceous hairs. There are 
leither scales on the genital lobes nor ventral tuft on the eighth segment. 
Occurrence .—Larvae taken from a pool within tidal influence at Port 
Swettenham and also in pools near Kuala Lumpur. 
Remarks .—A very distinct species in some points resembling Barbirostris, 
but easily told from that mosquito by the broad tarsal banding of the hmd 
leg, the absence of a pale apical fringe spot on the wing, and of a pale spot 
opposite the lower branch of the fifth vein. The wing has fewer golden 
scales than Barbirostris and the lateral scales are rather broader than m 
that mosquito. The scales at the base of the palpi and proboscis are not 
so long as in Barbirostris and the palpi are longer. The larva is evidently 
capable of living in water of a very high degree of salinity, the water of the 
pool at Port Swettenham in which larvae were found contained 2.8 parts 
of saline matter (chiefly sodium chloride) in 1,000 parts. It is a very 
large mosquito and the larva is the most intensely black of any of this group. 
Myzorhyncus Umbrosus. — Theobald. 
Palpi, black with a tuft of long white hair-like scales on the vertex, 
and dark blackish-brown upright scales elsewhere. Thorax, deep brown 
with Dale golden hairs. Wings, with only one costal spot and one small 
pale fringe spot where the third vein joins the costa. Legs, narrowly banded. 
Female Head .—On the vertex projecting forwards between the eyes a 
tuft of long silky white hair-like scales, immediately behind these on either 
side of the middle line a few white narrow curved scales, and behind these 
a cr ain two or three rows of bluish-white upright scales followed by numerous
