Male. Head as in the female. Antennae, with light brown joints and 
pale fawn-brown plumes. Palpi, with two last joints enlarged, ultimate 
joint, ochraceous with a narrow ring of dark brown scales at the base and 
on the whole ventral surface, its upper surface covered with creamy-white 
scales, penultimate joint scaled exactly like the ultimate, antepenultimate 
wuth dark brown scales and a narrow' ring of white scales about its centre. 
4 here are the usual differences from the female in the wing, viz., shorter 
fork cells and less dense scaling. Fore ungues unequal, larger ungues with 
one (? two) teeth, smaller simple. 
Occurrence. One adult fly, caught in hut at Ulu Gombak. Larvae 
taken from hill streams in jungle near Kuala Lumpur and at Tu^ra and 
“The Gap.” J ° 
Remarks. This mosquito evidently bears a strong resemblance to 
Nyssorhyncus maculatus , specimens of which have been taken at Taiping. It 
differs, howe\ er, in the banding of the palpi. A drawdng of the palpi 
Maculatus is given in Theobald’s “ Monograph ,” and shews three white bands 
at the apex, instead of two equal bands present in Willmori. On carefully 
comparing the descriptions of the two, I find besides the difference men¬ 
tioned, another point of distinction in the banding of the legs. The fore and 
mid metatarsi in this mosquito have three broad creamy bands one of which 
is apical, in maculatus the metatarsus has only one apical band. The two 
first tarsal joints in Willmori have apical and basal bands, in Maculatus only 
the first joint has basal and apical, the second has a basal band only. 
Nyssorhyncus Nivipes. — Theobald. 
Thorax black, clad with broad fusiform wdiite scales. Palpi, black 
scaled with white apical bands on the second, third and fourth joints, the 
fifth is pure white. The last three tarsal joints and half the first joint of 
the hind leg are pure white. 
Female Head. —Black, on the vertex projecting forwards betw r een the eyes 
is a tuft of long silky white hair-like scales, and along the upper part of each 
orbital margin is a row of narrow-curved white scales, behind these are a 
few rows of white upright scales and further back numerous black upright 
scales which extend outwards on each side. Basal joint of antenna, black 
with a tuft of small white scales on its outer side, remaining joints, black 
with white scales on the second and third and white downy hairs on the 
succeeding joints; verticillate hairs, white. Palpi, clad with black scales with 
narrow ring of white scales on the apex of the second, third and fourth 
joints, the last being entirely white. Proboscis, entirely covered with black 
scales. 
Thorax.- Prothoracic lobes, blackish-brown, clad with a few white fusi- 
orm scales. Mesonotum, black with broad fusiform white scales arranged 
in lines on the dorsum, a tuft of lanceolate scales on the anterior margin pro¬ 
jecting over the neck, and a tuft of dark scales on each shoulder above the 
prothoracic lobes. The scales running down the middle of the mesonotum 
are not quite so broad as those at the sides. Scutellum, similar in colour and 
scalmg to the mesonotum. Pleurae, dark brown, with darker brown spots and 
clad with a few small white scales. Wings clothed with dark brown and 
pure white scales, the brown scaled costa broken by six white spots, the
