[ IJ 4 ] 
Female Head .—Deep purple, clad with broad scales elongated spatulan 
with concave ends. These scales shew interruption colours in a fresh specimer 
and may appear deep gold or rose-purple, in a dry specimen they fade anti 
become pale gold or in some lights azure-blue or peacock-green. There 
are a few black upright scales on the nape. Basal joint of antenna 
pyramidal in shape blackish-brown and with a few scales on the inner face 
Antennae unusually long, second joint as long as any two succeeding joints 
Remaining joints deep purple with dark brown verticillate hairs. Palpi 
clad with golden scales at the base and black at the apex. Proboscis clac 
with dark purple scales above, golden below. 
Thorax. Prothoracic lobes blackish-brown in some specimens, lighn 
brown in others, clad with long bristles only. Mesonotum deep purple- 
brown in some specimens in other light brown with deep purple lines and 
patches clad with black narrow-curved scales and bright golden scales anc 
bristles on either lateral margin. Scutellum deep brown with black 
narrow-curv ed scales. Pleurae bright ochraceous or light yellowish-brown. 
Wings clad with dark purple scales, the median scales on the first Ion" 
vein consist of a double row of rather broad short oblique-ended scales: 
on all the other veins there is a single row of median scales and on the 
branches of the fork cells and the extreme apex of the third long vein 
there are a lew short broad fan-shaped lateral scales; fork cells very short 
of about equal length, the first narrower than the second, its base nearer 
the wing apex, its stem nearly twice as long as the cell; posterior cross 
vein less than half its own length from the median. Coxae and bases ol 
femora ochraceous; fore and mid femora ochraceous at the base and 
beneath; purple above; tibia clad with purple scales, the hind tibia with a 
broad pale golden band at the apex ; metatarsus and first two tarsals joints 
on fore and mid legs purple scaled with a narrow apical band of pale golden 
scales on each, hind metatarsus and first three tarsal joints with narrow 
golden band, last joint entirely clad with golden scales much brighter in a fresh 
specimen than in the dry. Ungues equal and simple. 
Abdomen .—First segment dark purple in the centre and ochraceous at the 
sides. A central longitudinal golden line runs the whole length of the 
abdomen from the second segment the rest of the dorsum being clad with bright 
purple scales. The venter is golden but when dry becomes golden-brown. 
Male. I n a typical specimen the antennae are densely plumose the plumes 
being bright flaxen but in others they appear more of a steel-grey. The 
proboscis is very long and clad with golden scales with a black band at the 
apex. The palpi are as long as the proboscis and apparently consist of only 
two joints the ultimate joint being clavate with black scales at its 
a P ex > golden-brown at its base, penultimate joint bright golden with a 
black band at its base in its centre and at its apex. Fore and mid ungues 
unequal the larger unguis with one tooth. 
Occurrence .—-Described from a series bred from larvae taken in marshy 
ground round Kuala Lumpur and elsewhere. 
Remarks .—A very distinct mosquito the swollen clubbed male palpi the 
peculiar shape of the head scales and the long antennae being all points 
peculiar to members of this genus. The three species known are very 
similar in colouration.
