ventral surface ; there is no other marking on any of the legs the remainder 
of all being clad with the dark purple-brown scales; ungues equal and 
simple on all the legs. 
Abdomen. —Slender; entirely clad with rich purple-brown scales with 
large pearly-white apical lateral spots ; venter clad with pale golden scales. 
The spots almost meet above in some specimens but never enough to give 
the appearance of banding. 
Male .—Antenna slightly plumose last two joints elongated. The 
pearly-white patch on the side of the head is more marked the proboscis is 
longer and the fore and mid ungues unequal the larger unguis shewing a 
minute process in place of a tooth ; the scales on the fork cells in the wing 
are broader than those on the female wing, and the lateral patch on the 
eighth segment is much larger than any of the others. 
Occurrence .—Described from a series of males and females bred from 
larvae taken from water in bamboo at Bukit Kutu and Ulu Klang. 
Remarks .—The light orange-coloured mesonotum the black scaled 
prothoracic lobes and the narrow wing scales constitute a ready means 
of distinguishing this mosquito from C. Similis, which has a black 
mesonotum and silvery scales on the prothoracic lobes. From C. Hybrida it 
is distinguished by the colour of mesonotum, and the colour of the scales on 
the prothoracic lobes and on the mesonotum. 
COLONEMYIA SlMILIS. N. SP. 
A large patch of deep ultramarine-blue scales on the upper part of the 
head in front, with dark purple scales behind and at the sides. Thorax 
dark brown. Proboscis very long. Abdomen with broad pearly-white 
lateral spots largest on second, fifth and seventh segments. Femora with 
pearly-white spots. 
Female Head .—Dark blackish-brown entirely clad with spatulate scales 
set in imbricate rows. In front stretching from the vertex backwards to 
about one-third of the distance between vertex and occipital foramen is a large 
patch of scales which are deep ultramarine-blue in the living specimen but 
may fade to a paler blue or almost white in the dried specimen; the patch 
is semi-circular towards the nape, and it is bounded by dark purple-brown 
or bronze scales which extend back to the occipital foramen and laterally 
down the orbital margin; beyond these on the orbital margin there is a 
patch of pearly-white scales. The blue scales vary with the direction of the 
light looking almost white in some lights in others a beautiful violet. There 
are two or three rows of dark brown upright forked scales behind on the 
nape. Basal joint of antenna bright brown with a few black hairs on the 
inner face and one or two small scales below these hairs, second joint with 
small scales dark brown in colour, remaining joints dusky-brown with white 
downy hairs ; verticillate hairs long, dark brown in colour. Clypeus dark 
brown with a few short hairs on its upper surface. Palpi about one-seventh 
the length of the proboscis, joints concealed by scales dark brown in colour. 
Proboscis of great length, as long as the whole body, clad with dark 
purple-brown scales.
