Rubithoracis the scales on the eighth and ninth joints are longer in 
Rubithoracis than in this mosquito while on the tenth joint there are no 
:ales in L. Rubithoracis. The mosquitoes differ in colour L. Rubithoracis 
eing much lighter and the wing scales on the male of this mosquito are 
eavier and broader than those on the wing of the male L. Rubithoracis. 
Lophoceratomyia Sylvestris. n. sp. 
Head with well-marked silvery orbital margin and golden vertical 
ristles. Thorax blackish-brown, pleura greenish ; proboscis, legs and 
bdomen blackish-brown. 
Female Head. —Blackish-brown with a row of silvery elliptical scales 
long the orbital margin of either side, pale brown narrow-curved scales in 
ae centre, and outside these a few spatulate scales which take the colour 
f the background, and beyond these a patch of blue-grey spatulate scales ; 
pright forked scales dark brown and inserted over the whole of the upper 
ortion of the head ; on the vertex are two conspicuous golden bristles, 
fill the above may be much altered when the specimen drys the silvery 
rbital margin entirely disappearing as that part shrinks beneath the darker 
ortion of the head. Basal joint of antenna dark brown with silvery hairs 
nd dark brown verticillate hairs. Palpi about one-sixth the length of the 
roboscis clad with scales which are almost black. Proboscis clad with 
>rown scales, bronze-purple in some lights. 
Thorax .—Prothoracic lobes dull black, without scales. Mesonotum 
usky, clad with bronzy narrow-curved scales. Scutellum paler than the 
nesonotum clad with black narrow-curved scales and with dark brown 
>ristles, four to the central lobe. Pleurae colourless usually green tinted 
rom thoracic contents. Wings clad with dark brown scales of the usual type ; 
ork cells long, the first longer and narrower than the second, its base slightly 
tearer the wing base, its stem scarcely half the length of the cell; posterior 
ross-vein three times its own length from the median. Coxae colourless clad 
vith a few white scales. Femora dull white beneath dark brown above 
.nd laterally; remainder of legs with dark purple-brown scales ; ungues 
•qual and simple. 
Abdomen .—Clad with blackish-brown scales above dirty-white beneath. 
Male .—Head with well marked silvery line of scales along the orbital 
nargins and in addition there are a few silvery narrow-curved scales on the 
/ertex and laterally the scales are paler than those on the female head. 
The basal joint of antenna is not such a dark brown as that in the female ; 
emaining joints pale silvery-brown with dark brown crescentic ridges for 
he insertions of the verticils. The scale tuft on the sixth joint is confined 
o the outer side ; it consists of a few (four or five at the most) dark brown 
leedle-like scales; the tufts of crumpled scales on the seventh, eighth and 
finth joints exactly resemble those in L. Variata; the verticillate hairs 
in the joints beyond the tenth are very long and at their bases are bright 
faxen. Fore and mid ungues unequal the larger uni-serrate. 
Occurrence .—Bred from larvae found in the still pools in the jungle. 
Remarks.— This mosquito somewhat resembles M. Niger but should 
lot be difficult to distinguish from that species. The white line along the
