[ 94 ] 
Male. Scaled as in the female. Antennae plumose with purple- 
black hairs; joints dusky at the base silvery at the apex. Palpi a little 
shorter than the proboscis black scaled and without hairs except on the 
apex of the terminal joint where there is one stout black hair and a few 
short slender hairs. In all other respects male resembles the female except 
that the fore and mid ungues are unequal but simple. Genitalia are rather 
complex but not easily seen. 
Occurrence .—A small stegomyia bred from larvae taken from the water 
collected at the bases of the leaves of an atap palm in the mangrove 
swamp, Port Swettenham. The adult is a blood sucker and common in 
jungle where atap palms are common. 
Genus 8.— Leicesteria.— Theobald. 
Head with large spatulate scales and upright forked scales confined to 
the nape. Proboscis thick. Palpi more than half the length of the pro¬ 
boscis in the female, in the male very slender and longer than the proboscis 
by the last joint. Mesonotum clad with hair-like scales on the dorsum and 
large spatulate scales on the margins and in front of the scutellum. 
Scutellum with spatulate scales. Large mosquitoes with very long 
slender abdomens and with thorax arched forwards over the neck and 
head. 
Remarks. This genus is founded on specimens sent from here to Mr. 
Theobald. Four species have been found all easily recognised by the long 
female palpi a character which marks every species and distinguishes them 
from Desvoidya which they somewhat resemble. They are all sylvan 
vicious day biters and all appear to breed in the water in bamboos. 
Leicesteria Longipalpis. — Theobald. 
A slender rather small mosquito with unbanded legs but conspicuous 
white lateral bands to the abdomen. The female palpi are very long fully 
two-thirds the proboscis. 
Female Head. Black, the vertex occiput and nape covered with broad 
spatulate black scales, and along the orbital margin a narrow row of 
spindle-shaped creamy scales ; laterally where the black scales end is a 
band of creamy scales and then black scales again. There is a moderate 
number of black upright forked scales confined to the nape. Basal joint of 
antenna, pale dirty yellow, the inner face thickly clad with small flat 
scales with a few dark ones interspersed ; the basal half of second joint is 
similar in colour to basal joint the apical half and the succeeding joints of the 
amennae are black covered with numerous short white hairs ; verticillate 
hairs black ; last joints of antennae not elongated. Clypeus dark brown with 
a few narrow white scales on its anterior margin. Palpi four-jointed clad 
with black scales, third joint very long, longer than all the other joints put 
together, fourth joint minute. The palpi in this species are unusually 
long being fully half the length of the proboscis. Proboscis thick clad with 
black scales. 
Thorax. Prothoracic lobes thickly clad with spatulate scales, white 
on the lower half, black above, while from the apex a tuft of
