A very black mosquito of medium size. Head black with narrow 
very orbital margin. Thorax black with white shoulders and broad 
very margins in the male. Abdomen black above with triangular silvery 
ots and I white band at the base of the fifth and sixth segments. Legs 
tirely black. 
Female Head .—Entirely scaled with black spatulate scales except for a 
iale row of silvery scales along the orbital margins and a few black narrow- 
rved scales on the nape seen with great difficulty and not at all unless 
e head is well flexed on the neck exposing the posterior portion, 
srtical bristles pale brown, orbital black. Basal joint of antenna b ack 
ith silvery piriform scales, remaining joints black with black vertici late 
lirs. Palpi about three-quarters the length of the proboscis and black

lypeus black and nude. 
Thorax .—Prothoracic lobes black, clad on the anterior face with 
Ivery spatulate scales, behind above with blackish narrow-curved sea es 
id below with silvery broad curved scales. Mesonotum black clad with 
amerous black narrow lanceolate scales but little curved ; shoulders 
ad with silvery fusiform scales, a few narrow silvery scales m 
out of each wing which do not extend as far forwards as the shoulder, 
'he scales on the mesonotum towards the base _ of the scutellum are 
roader than the scales in front and at the junction of mesonotum and 
cutellum the scales are long spatulate scales. Scutellum dark reddis 
rown at the base, black at the apex, clad with large spatulate black scales 
nd brown bristles six or seven to middle lobe. Pleura black with patches of 
Livery spatulate scales. Wings clad with black scales rather broader than

ut on the branches of the second vein the scales are much broader and 
horter ' first fork cell longer than second, its base nearer.the apex of the \\ mg 
:s stem about two-thirds the length of the cell; posterior cross vein about 
* long as the median from which it is distant less than its own ength Coxae

inder sides of hind femora which are silvery and very spiny; fore and mid

Abdomen .—Dorsally clad with black with a small silvery patch on the

ieven segments. 
Male .—The silvery margin along the eyes is broader than m the 
emale, the antennae are plumose with a black basal joint and the othe 
oints white ; the palpi are longer than the proboscis and the last tv o jo s 
tre about equal. On either margin of the mesonotum there is a \ ery broa 
oand of silvery scales ending at the bases of the wings. A narrow silvery
