Abdomen. —Dark purple-brown with pale lateral translucent areas at the 
mses of the segments, covered with numerous tawny hairs specially dense 
)n the apical segments. The last two segments are covered with narrow 
curved scales very dense on the genitalia, golden-yellow in colour. 
Male Head. —The colour and scaling is that of the female. Basal joint 
)f antennae, large, dark brown, and as far as one can see, without scales, the 
second joint is very short and heavily scaled with white scales. All the 
Joints beyond the first are translucent and of a muddy-white colour being 
iarker at the insertion of the verticils. The two terminal joints are black 
md elongated. The plumes are very dense and light brown in colour. 
Palpi, with the first apparent joint slender, black scaled, the scales at the 
base long and clavate, while about the centre there is an absence of scales 
giving the appearance under a hand lens of a narrow band, the second and 
:hird joints are entirely black scaled beneath, above and at the sides, they 
ire clad with snowy-white scales, the ultimate joint having a narrow black 
oand at its base. For the rest the male resembles the female. 
Occurrence. —Larvae taken at Jugra and near Kuala Lumpur in the 
grassy edges of slowly flowing streams. 
Remarks. —This mosquito is easily told from Maculatus and YY illmori 
sy the absence of spots on tibiae and femora and by the different banding of 
the palpi and hind legs.
