Male Head .—Scaled as in the female. The antennae have pale inter- 
odes and dark nodes, and the two last joints are very long ; verticillate 
airs long and black. Palpi about four-fifths the length of the proboscis, 
irty white and clad with black scales. A naked area in the middle of 
icond joint shows white under a lens. White scales which may or may 
ot form a complete band at the apex of second and third joints. These 
:a les may involve both sides of the joint. They are variable. Proboscis 
)n o-, black scaled with a narrow band of white scales about its centre, 
"he'thoracic scaling is the same as in the female and the leg scaling also. 
Ving scaling similar but not so heavy. Abdominal banding more marked 
.11 the segments showing fairly broad basal white bands and large lateral 
pots. The penultimate segment has a dorsal patch of white scales with a 
,early lustre. The fore and mid ungues large unequal larger unguis 
•iserrate. 
Occurrence .—This mosquito is a very distinct species. It is a bamboo 
ireeder the other species is rarer and apparently only breeds in rock pools 
upplied by a river. It is by no means a common mosquito is entirely 
;ylvan and a blood sucker. It has been caught at Bukit Kutu and in 
ungle on the Pahang Road five miles from Kuala Lumpur and at Liu 
3 ombak thirteen miles from Kuala Lumpur but as it is a bamboo breeder it 
s probably to be found wherever bamboo is plentiful. The band on the 
iroboscis is very variable and in some specimens it is entirely absent m 
others only marked on the under side. 
Time of capture at Bukit Kutu in May and in the neighbourhood of 
Kuala Lumpur April, May, July, October and December.

Helecocteomyia Jugraensis. n. sp. 
Head with golden orbital margins and creamy central line with blackish- 
brown patches on either side of this with a band of white scales low 
down laterally. Thorax with variable ornamentation but as a rule with 
one central golden unforked and a short line on either side of the posterior 
half of the mesonotum. Pearly lateral spots on the last four abdominal 
segments. 
Female Head. —Black. Viewed from above there is seen a central line 
of creamy narrow-curved scales with similar scales scattered irregularly 
over the nape, a row of pale golden scales along the orbital margin of 
either side and dark patches of spatulate blackish-brown scales o\er the 
rest of the head with numerous rows of black upright scales inserted as 
far forwards as the vertex. If the head is viewed from the side a 
lateral band of white scales can be seen but this is too low down to be seen 
when looking down upon the upper surface. Vertical bristles creamy-yellow. 
Clypeus deep brown. Palpi about one fifth the length of the proboscis clad 
with black scales and in some specimens shewing two or three white scales 
at the tip. Proboscis long, longer than the abdomen, clad with black 
n scales. 
Thorax .—Prothoracic lobes black clad with small elliptical silvery 
scales. Mesonotum deep chestnut-brown entirely co\ered with blackish-
