surface only. When the specimen dries the palpi become so distorted that 
the amount of white scaling is made out with difficulty. The wing is much 
more lightly scaled than in the female and there is only one dark spot on 
the sixth vein. The lateral aspects of the abdomen are fringed with long 
jchraceous hairs. The genital lobes are densely clad with dark brown 
scales. 
Occurrence.— The larvae are to be found in any large collection of water 
in the open, such as lakes and large ponds supplied by springs. They are 
not to be found in very stagnant water. 
Remarks .—Described from a large series bred from larvae. The larvae 
differ constantly from those of M. Sinensis. The wing scaling also differs 
from that of M. Sinensis as it is much darker and the contrast of the two 
colours is more pronounced and the lateral scales are broader.. The 
posterior cross vein is much nearer the median in M. Sinensis than m t is 
mosquito. 
In the larva of M. Sinensis each frontal hair consists of a short thick 
stem supporting numerous stiff bristle-like hairs, in M. Peditaniatus it is 
formed by a long thin stem which splits into a few (five or six) fine hairs. 
Myzorhyncus Barbirostris. 
A large black mosquito with very heavily scaled palpi and proboscis. 
Thorax, dark slate with golden hairs. Palpi, without white bands. Y\ ings, 
with two costal spots and a pale spot on the fringe opposite the lover bianch 
of the fifth vein. Legs, minutely banded. 
Female Head.— Black. A tuft of long hair-like ochraceous scales and a 
few shorter or narrow curved scales on the vertex, behind these, one, or per¬ 
haps two rows of bluish-white upright scales, succeeded by scales vhich are 
black in some lights, blue-black in others. Basal joint of antenna, black, 
with a few small black scales on its upper face, second joint black, as long 
as any two succeeding joints, and clad with a few brownish-black clavate 
scales, remaining joints black with white downy hairs and black verticils. 
Palpi, as long as the proboscis, clad entirely with black scales, vhich, vhen 
dry, have a brownish tinge ; towards the base they are very long and stand 
out from their insertion, making the palpi appear very thick. Pioboscis, 
black scaled. 
Thorax .—Prothoracic lobes, black, with a tuft of black cla\ ate palisade 
scales on the apex of each. Mesonotum, black with a silvery frosting, clad 
in front just over the neck with rather long narrow white scales, and on 
either shoulder above the prothoracic lobes with a tuft of cla\ate.palisade 
scales, dark blackish-brown in colour, the rest of the mesonotum is thinly 
clad with hair-like scales which are creamy, with some pale golden ones inter¬ 
mixed ; scutellum, black, with creamy hair-like scales and golden bristles. 
Pleurae, black, with a few long hair-like creamy scales below the wing,, and 
some clavate scales on the portion between front and middle coxae.. m o s > 
Jj! narrow, clad with black and creamy scales, these latter are sometimes pale 
yellow. Costa, clad with black scales, except where the subcosta joins .it, 
!i where there is a creamy spot and at the apex where the first long vein joins 
i the costa is 'another small creamy spot; subcostal vein entirely black
