and short hair-like curved scales. Prothoracic lobes have a few 
hairs on them. 
Abdomen has no scales on either surface, hut long brown 
hairs. 
Wing is spotted, with costa showing seven dark spots, four long 
and three short. Sub-costal vein has two dark spots below the 
fifth and sixth costal spots. The first longitudinal has four black 
spots, the second is divided into two, sometimes three. The 
second vein has two black spots on main stem, two on upper and 
three on lower stem of each branch—often one spot is wanting on 
each. The third vein has two small patches near its origin and 
one near its termination—this is most constant. The fourth 
long vein has two long black spots on the main stem and two on 
each branch. The fifth has one small spot on the main stem, 
two on the upper and one on the lower branch. The sixth 
vein has three spots, one near its origin, one in the centre and 
one at its termination. The wing fringe is dark with white areas 
at the junction of all the veins and with a white spot between 
the junction of the sixth vein and the base of the wing. This 
spot is sometimes absent. 
Legs dark brown and yellowish bands at all the joints. The 
femora and tibia of the hind legs are speckled, the latter often has. 
a well marked band at its lower end ; ungues are simple and equal. 
$ . The upright forked scales are better marked, otherwise the 
cephalic ornamentation is the same as in the female. Palpi are 
lightly scaled, the lowest band is the same as in the female, though 
less distinct. The next band is situated at the junction of the 
club-shaped apical segment with the lower end, then follows a 
long white band, then a small black patch, which is sometimes 
wanting, and lastly the apex is white. The thorax and abdomen 
are the same as in the female, sometimes a few spindle-shaped 
scales are seen on the last abdominal segment. Genitalia ; basal 
segment is curved and globular, covered with brown hairs, apical 
segment is long and narrow terminating in a point.

Observations .—The above account is taken from Patton. It 
is certainly not an Anopheles , but the description lacks sufficient 
technical details to place it in its proper place, at least if the 
scale structure is properly recorded. It is important to settle this 
species as Patton says (p. 626) :—“ It is the common Anopheles 
of the district, and, as far as the writer can say, the only certain
