» not always present. They are fairly common mosquitoes in the jungle 
i often appear in houses if there is any jungle in the neighbourhood, 
ley are vicious biters. They lay their eggs as single black thick-shelled 
very like those of Stegomyia. The larvae aie large and stout 
th very short respiratory syphons and greatly enlarged anal papillae, 
leir position is vertical to the surface of the water and they are mainly 
ttom feeders. Generally speaking their breeding habits are similar to 
)se of Stegomyia.

if* 
Head entirely clad with black scales except for a narrow silvery margin 
the eyes and a few pale scales on the nape. 1 horax with well marked 
irginal band of scales creamy or pale ochraceous and bronze scales on the 
rsum. Scutellum with large spatulate blue-black scales sometimes with 
me pale ochraceous ones on the central lobe. Legs with white knee 
ots. Abdomen with large triangular lateral patches. 
Female Head. —Black, on the space between the eyes are a few silvery 
rrow-curved scales and there is a small patch of similar scales in the 
ntre on the nape ; along the orbital margin of either side is a row of small 
very spatulate scales and low down on either side is a patch of similar 
ales; all the rest of the head is clad with large blue-black spatulate scales, 
cept that on the nape in front of the patch of narrow-curved scales are 
ree or four ochraceous spatulate scales. Unless the head is well separated 
om the thorax the patch of white narrow-curved scales cannot be seen, but I 
ive a large series of these mosquitoes and some of them shew this patch 
ry plainly. Vertical and orbital bristles brown. Basal joint of antenna 
rruginous with darker shading on the inner side, the inner and lower face 
clad with small silvery spatulate scales, second joint pale at its base deep 
own at its apex with a few dark brown scales, remaining joints deep 
own with dark brown verticils. Palpi almost one-third the length of the 
oboscis clad with blackish-brown scales. Clypeus purple-brown with 
very spatulate scales. Proboscis thick especially the apical third, clad 
ith blackish-brown scales. 
Thorax .—Prothoracic lobes deep purple, in front and below clad with a 
ixture of silvery scales some being spatulate others broad crescentic,. 
)ove and behind it is clad with dark bronze scales also of two shapes, 
he line separating the two colours is oblique passing from above down- 
ards and backwards. This differential scaling of the prothoracic lobes 
by no means uncommon in members of the Culicidae though it does not 
hem to have attracted any attention. A row of long dark brown bristles 
ins down each lobe. Mesonotum chestnut-brown with a purple tinge 
msely clothed with long hair-like bronzy scales ; on the anterior margin 
/er the nape and shoulders are patches of ochraceous rather broad cres- 
mtic scales, and on either shoulder is a large patch of similar scales while 
ong the lateral margin running backwards over the wing roots is a band 
broad crescentic scales ochraceous or sometimes white in colour. In a 
ell-preserved specimen this marginal band is very conspicuous but ne\ er 
) broad as in D. Jugraensis. In most specimens in the centre of the
