scales at the base. The penultimate joint is much thicker than the 
ultimate and is more or less barrel-shaped, there is a broad white band in 
the centre of the anti-penultimate joint. The mesonotum is lighter brown 
than in the female and the posterior fourth is clad with white scales. 
Abdominal segments with well-marked basal bands. Fore and mid ungues 
unequal the larger unguis toothed. 
Occurrence. Described from a series bred from larvae in water collected 
in the pools and ruts in a jungle waggon track at Ulu Klang near 
Kuala Lumpur. 
Remarks. —As the scutellar scaling and the palpi are quite distinct from 
those of a culex I have no hesitation in placing this mosquito in a separate 
genus. 
Genus 25.—Theobaldia.— Neveu-Lemaire. 
Formerly included in Culex. Not known to occur in Malaya. 
Genus 26.—Lutzia.— Theobald. 
Like Theobaldia separated from Culex in which Genus it was formerly 
included. No species of the genus known to occur in Malaya. 
Genus 27.— Melanoconion.— Theobald. 
I he species in this genus closely resemble Culex, but the apices of 
the wing veins are clad with large clavate lateral scales. 
Remarks.— Only one species of this genus occurs in Malaya and it 
presents peculiarities which in my opinion make its position here dou >tful. 
Mr. Theobald classified it from specimens I sent him but the very peculiar 
male palpi seem to have been overlooked, and the wing scaling is more that 
of a Culex than a Melanoconion. 
Melanoconion Uniformis. — Theobald. 
A very variable mosquito as to size and colouring. Thorax a dingy 
washed-out black tinged with green from thoracic contents clad with pale 
brown scales. Wing scales more linear than clavate and hence resembling 
the scales of a culex wing rather than that of other members of this genus. 
Legs and abdomen with dark brown scales. Male palpi about 
two-thirds the length of the proboscis and of a very peculiar shape. 
Female Head. —When fresh of a dark mouse-grey but in the dried 
specimen if the head is much shrunken it appears dark purple-black. In one 
specimen I have it is pale fawn-brown. Along either orbital margin there 
is a line of silvery-white narrow-curved scales the rest of the upper surface 
is very sparsely clad with golden-brown narrow-curved scales and numerous 
very long golden-brown upright forked scales ; low down on the sides there 
is a patch of silvery-grey spatulate scales very difficult to see and not seen 
at all when one looks directly down upon the upper surface of the head; 
vertical bristles very long and dark brown, orbital bristles paler brown. 
Basal joint of antenna dull brown with darker shading on the inner side 
where there are a very few small scales, remaining joints dull brown with 
dark brown verticillate hairs. Clypeus dull brown, pale ochraceous in one 
specimen. Palpi about one-eighth the length of the proboscis clad with 
dark brown scales. Proboscis enlarged towards the apex, clad with dark 
brown scales, purple-bronze in some lights.
