the border and another further back, and many dark scales from 
this to the base. First sub-marginal cell longer and narrower 
than the second posterior cell, its base a little way in front of 
the costal spot. 
Length. —4*5 to 5 mm. 
Habitat .—Calcutta (Daniels) (7. 4. 1899) ; Naim Tal (Giles) ; 
Travancore (James). 
Observations .-—Three bad specimens only in the collection, for 
which Major Giles suggests the name of nigerrimus in his 
compilation on Culicidae. There is not sufficient material, how¬ 
ever, to express an opinion definitely. It is very clearly related 
to A. Sinensis , of which it is no doubt a sub-species ; annularis is 
its nearest relative, but it differs from it in that the scales of 
the wings seem to be less elongated ; the apical fringe is also 
black, and there is a pale patch at the end of the lower half 
of the fifth long vein, thus-bringing it near to A. barbirostris as 
well as to A. Sinensis, sub-species annularis. 
This is one of the dapple-winged mosquitoes of Ross, the three 
specimens in the Museum having been presented by him. 
Major Giles has also sent me recently a specimen from 
Nairn Tal.

(Leyden Museum Notes, vi. p. 48.) 
(PL A.) 
Thorax deep greyish, with slaty reflections, dark longitudinal 
lines and minute black specks, with long scattered golden hair¬ 
like scales. Abdomen nearly black. Legs dark brown, with 
apical pale bands to the tibiae and tarsi. Costa black, with two 
small yellow spots on the apical half; apical fringe black, except 
between the second and third veins; scales more robust than in 
A. Sinensis. (Vide Plate A.) 
9 . Head black, covered with black upright broad forked 
scales behind, grey at the tips, and with creamy white ones in 
front, a median bare space and a few projecting white and black 
bristles in front ; antennae black, with pale bands, basal joints 
black; palpi densely covered with deep black scales, making 
them nearly as wide as the head, as long as the proboscis, all 
traces of the joints hidden by the dense scales. 
Thorax deep greyish, with slaty reflections, deeper coloured 
thin longitudinal lines, and numerous dark specks covered with
