CULEX ALIS. nN. Sp. 
Thorax brown, ornamented with brown and pale scales, the 
latter on each side in front and forming two large pale spots 
towards the centre of the mesonotum, and also pale in front of 
the scutellum. Head dark brown, with paler scales, creamy 
white at the sides; proboscis deep brown, with a median pale 
band. Abdomen brown, with pale basal bands ; legs deep brown, 
with narrow pale basal bands to the joints ; the tibio-metatarsal 
jeint pale on each side. Wings with the fork-cells short, their 
stems longer than their cells, the base of the first sub-marginal 
much the nearer to the apex of the wing. 
Q. Head deep brown, with narrow-curved, pale golden scales 
and flat white ones at the sides of the head, border round the 
eyes pale, there are numerous ochraceous, upright forked ones 
over the occiput; clypeus, palpi and antennae deep brown, 
the former with whitish hairs at the tips; proboscis deep 
brown, with a narrow yet pronounced pale creamy median band. 
Thorax deep brown, with golden brown narrow-curved scales, 
they are of a creamy colour at the sides of the front of the 
mesonotum, and spread on to the dorsum about its middle, 
forming two large pale spot-like areas ; there are also pale scales 
around the bare space in front of the scutellum ; bristles black ; 
scutellum brown, with narrow-curved pale scales and six black 
border-bristles to the mid lobe; metanotum brown; pleurae

also base and venter of femora, knee-spot indistinctly pale on the 
fore and mid legs, but white in the hind ; tibio-metatarsal joint 
yellow, the band involving both sides of the joint, especially in 
the hind legs; narrow pale basal bands to the metatarsi and 
tarsi scarcely perceptible on the last tarsal of each leg ; ungues 
small, equal and simple. 
Wings densely scaled, with rather long broadish brown scales ; 
fork-cells relatively short, the first sub-marginal cell scarcely longer, 
but narrower than the second posterior, its base much nearer 
the apex of the wing than that of the second posterior, its stem 
longer than the cell ; stem of the second posterior cell as long as
