is no pale patch on the wing-fringe, and the base of the first 
sub-marginal cell is a little nearer the base of the wing than 
that of the second posterior cell. The costal spots are also 
smaller, and the majority of the specimens are not so large as 
those from China. Tan der Wulp thought it might be 
synonymous with A. Sinensis, and I am also of opinion that the 
two are mere local races. There is much variation in regard to 
the banding of the legs and palpi in this species, which is 
evidently very abundant in Perak. It answers so nearly to 
A. annularis that I adopt that name for this sub-species and 
apply A. barbirostris to the darker Anopheles from the same 
locality. Walker’s A. vanus is evidently a £ of this, but the 
type is so denuded that it is difficult to say with certainty. The 
Sambalpur specimens have broad leg-bands involving both sides 
of the tarsal joints. 
Variability of the sub-species. —The large series sent by 
Mr. Wray, from Taipang, shows considerable variation both in 
size and markings, one distinct variety being easily separated 
from them ; this I call variety A, in which the bands of the hind 
tarsi invoice both sides of the joints. In some these bands are 
narrow, in others very wide. Although this variety can easily 
be separated from the type, there are forms which can be placed 
in either, several specimens showing partial apical and basal 
bands, some on one or more joints only, whilst in others the 
banding is so small as to be scarcely perceptible. The palpi 
also vary in regard to the white bands. 
Original description.*

longitudinal, fuscous lines ; pleurae light grey with black spots 
arranged in long rows. Antennae with light * brown hairs; 
rostrum black ; palpi fuscous, as long as the rostrum ; base of the 
first and second joints and the whole of the apical joint white. 
Legs long and slender, testaceous ; anterior tarsi with a ring of
