Genus Anopheles. 179 
taceous towards the apex; antennae dark brown, with pale 
pubescence, basal joint dark, the second with white scales. 
Thorax dark brown at the sides, broadly grey in the middle, 
with almost white narrow scales, those in the middle of the 
mesonotum a little broader than the rest, and with golden hairs, 
with darker longitudinal lines along the pale median areas; 
scutellum darker in the middle than the sides ; metanotum deep 
brown; pleurae dark chestnut-brown, with grey reflections often 
arranged as six spots. 
Abdomen blackish-brown (bluish-grey when alive), with 
scattered pale hairs. 
Legs dark brown to nearly black, with a few pale apical scales 
to the metatarsi and tarsi, often indistinct unless seen under the 
microscope ; ungues equal and simple ; hind metatarsi a little 
longer than the hind tibiae. 
Wings with the black costa with six pale creamy almost 
white spots, the three apical ones extending on to the first long 
vein, remaining veins with patches of white and black scales as 
follows : one small and one large dusky patch on each of the 
branches of the first sub-marginal cell, the greater part of its 
stalk dark scaled, a dark patch at the base and apex of the third 
long vein, two dark patches on each branch of the second fork¬ 
cell, and the greater part of the root and stem dusky, two dark 
patches on the upper and one on the lower branch of the fifth 
vein, another at the fork and another at the base of the vein, 
two small dusky patches on the sixth ; first sub-marginal 
cell considerably longer and a little narrower than the second 
posterior cell, its base much nearer the base of the wing than 
that of the latter, its stem rather more than half the length of 
the cell; stem of the second posterior cell a little longer than the 
cell ; mid cross-vein nearer the apex of the wing than either the 
supernumerary or posterior cross-veins. Fringe black, with pale 
spots at the junctions of all the veins, except the sixth ; apex 
mostly yellow, but with a black spot between the two branches of 
the first sub-marginal cell. Halteres pale, with a fuscous knob. 
Length .—3 to 3 5 mm. 
£ . Antennae blackish, with black verticillate hairs, paler in 
certain lights ; palpi with the apex grey, followed by a narrow 
black and then a grey ring, the remainder black scaled. 
Wings slightly different to the 9 ) the first sub-marginal cell 
is twice as long as the posterior cell, and its stem much shorter 
than the cell; the posterior cell is very short, and very little
