Town scales ; posterior cross vein commencing almost in a line with, but 
. little to the apical side of, the median cross vein ; fork cells, short. Coxae 
ilack, clad with silvery scales ; thighs rich purple above and at the sides, but 
>eneath the scales are pale, in some lights silvery-white, but in certain 
crhts shewing the most brilliant iridescent colours, blues and greens ; the 
emainder of all the legs brillant purple, the only attempt at banding being 
,n imperfect band on the first tarsal joint of the hind legs. This is only 
een below and at the sides. Fore and mid ungues unequal, the larger 
miserrate. 
Abdomen .—First segment clad with greenish-yellow metallic scales, 
emaining segments clad above with rich velvety-brown scales, almost 
>lack ; owing to shrinking, it is little difficult to say what the lateral orna- 
nentation consists of, but the first segments have distinct pale metallic 
yellowish-green lateral spots, and I believe these are present on all the 
•.egments, though they are hidden on the apical segments. There are also 
,vhite spots below these, and at the base of the caudal tuft there are 
Deacock-blue patches ; the venter is clad with velvety dark brown scales 
3xcept on the third, fifth and sixth segments which are entirely scaled 
>ilvery-white. The caudal tuft is black in some lights, rich purple-bronze 
n others. 
Occurrence .—Described from one male bred from a pupa taken in a 
oamboo in jungle about six miles from Kuala Lumpur. 
Remarks .—Evidently a rare species, and it is to be regretted I have no 
iemale. To the naked eye it is a very funereal looking mosquito, some of 
ihe more beautiful colours are only seen with a lens. 
Genus 3.— Toxorhynchites.— Theobald. 
Characters .—Head entirely clad with spatulate scales with a few 
upright scales confined to the nape. Thorax with fusiform, elliptical, and 
spatulate scales. Female palpi about one-sixth the length of the proboscis 
four-jointed and rather slender. Caudal tuft absent. Mosquitoes of slender 
build. Eggs and larvae as in the other genera of the sub-family. Two 
species occur here. 
Remarks .—The Malayan species of this genus are readily distinguished 
from the members of the other genera of this sub-family by the absence 
of the caudal tuft and generally more slender build. The larva of 
T. Leicesteri is very peculiarly marked and the pupa is pure black and 
has the paddles like the tail of a fish. 
Toxorhynchites Leicesteri.— Theobald. 
Slender mosquito of moderate size with a handsome metallic-green 
scaled thorax, purple abdomen banded with blue. Legs banded in the 
female. 
Female Head. —Black, covered with broad spatulate scales; along the 
orbital margin is a narrow band of scales broadening out laterally which 
are peacock-blue or in some lights rose-purple; the rest of the upper 
surface of the head is clothed with metallic-golden scales which may assume 
a golden-brown colour in the dry specimen. Immediately round the occipital
