yellow,' Tibiae violet-black sprinkled with yellowish scales. 
Tarsi violet-black, each joint with a narrow ring of white at the 
base, rather indistinct on the last two joints of the fore and 
intermediate legs. In the hind legs the metatarsus rather more 
than two-thirds the length of the tibiae. Wings longer than the 
abdomen, hyaline, with a pale yellowish tint anteriorly, veins 
covered with slender brown scales, cilia grey ; rather brilliant 
reflections. Auxiliary vein joining the costa a little before the 
posterior branch of the fifth longitudinal fork ; middle cross-vein 
longer than the posterior cross-vein, situated a short distance 
in front of the former ; first sub-marginal cell somewhat longer 
and slightly narrower than the second posterior cell, the base of 
the former situated a little beyond the base of the latter ; anterior 
branch of the fifth longitudinal vein originating opposite a point 
about mid-way between the origin of the second longitudinal 
and the tip of the sixth longitudinal vein, joining the posterior 
border opposite the middle of the second posterior cell. 
g . Head black, with pale golden curved scales and black 
and brown narrow upright forked ones, sides densely covered 
with flat white scales. Antenna? banded, plumes silky-brown 
and dull yellow, the top joints of the antennae dark ; proboscis 
dark brown, quite black towards the tip ; palpi almost black, 
the penultimate joint and apex of the antepenultimate swollen, 
the apical joint thinner, faint basal pale bands on the last two 
joints, hair- tufts yellow. Abdomen with basal white bands, 
the last segment unbanded, but with a few white scales, the ante- 
penultimate with the basal band expanded laterally, and with 
yellow apical scales ; densely golden haired. Ungues of fore 
feet unequal, the larger one with two teeth, the smaller with one ; 
hind ungues equal, each with a single tooth. 
Length, 4.8 to 5 mm. 
Tins is the " Black Bush-Mosquito," a most plentiful species 
everywhere in Southern Queensland, along the sea coast, more 
especially ; it bites all the year round, both by day and night, 
and the bite is very painfu 1 ; it sometimes occurs in millions ; 
it does not come into the house, which is about all that can be 
said favourably o+ it. It lays its eggs singly in salt water swamps 
and pools of sea water that are left behind after high spring 
tides and king tides ; the water in such pools becomes concentrated 
by evaporation, often up to a specific gravity of 1,060, but the 
larvae are uninjured ; small fish, if any, die before the water 
reaches a specific gravity of 1,040. Larvae have been found 
in fresh-water creeks a few miles inland from the sea,, but not 
in plentiful numbers. This mosquito prefers salt water. It 
can be told at a glance by its black colour and white banded 
legs. It extends into New South Wales (Skuse) ; specimens 
have been sent from the Johnstone River by Mr. A. Owen Jones 
and Mr. Edgar H, Webb.
