CULEX QUINQUEFASCIATUS 349 



length of the thorax in the J', shorter in the $; dorsally dark violet-scaled, each seg- 

 ment narrowly ochre-banded in front; venter whitish-scaled; external genitalia 

 ochreous, densely haired. Legs violet-brown scaled, the femora with whitish scales, 

 and slightly at the base, the latter and the tibiae very slightly ochre-tipped; tibiae 

 and tarsi with a pale ochreous reflection beneath; coxae brownish-yellow, with white 

 scales. Wings longer than the abdomen, hyaline, veins densely violet-brown scaled. 

 Auxiliary, joining the costa opposite the tip of the hinder branch of fifth longitudinal 

 vein; middle about equal to the posterior transverse vein, placed twice the length 

 of the latter in front of it; first sub-marginal longer, and somewhat narrower than 

 the second posterior cell, its base opposite that of the latter in the c^, slightly before 

 it in the $; anterior branch of fifth longitudinal originating at a point nearer the 

 origin of the second than to the tip of the sixth longitudinal vein. 



Observation. Individual specimens of this species apparently vary somewhat in 

 colour, as nearly every reference to colour is in the original, expressed by several 

 nearly synonymous words. Considerations of space render it impracticable to give 

 these in full. The same remark applies to a less extent to many others of the species 

 described by this author. 



Habitat. Widespread in Australia. Found in towns, throughout the year, but 

 most annoying during the summer. 



Original Description of Culex quasipipiens: 



Thorax brown, with narrow curved golden scales. Abdomen brown, with curved 

 very pale yellow to white basal bands, last segment often pale scaled. Legs un- 

 handed, brown; knee spot pale; ungues equal and simple. Wings much as in 

 C. pipiens, but the stem of the first sub-marginal a little longer, and the posterior 

 cross-vein considerably further off, and the relative positions of the sub-costal, costal, 

 and the base of the first fork-cell different. Head with pale scales. Thoracic scales 

 broader than in C. pipiens. 



5. Head deep brown, with very narrow grey curved scales on the occiput, and 

 black upright forked scales, which form a black patch on each side near the neck, 

 a narrow band of pale scales bordering the eyes, and a row of six bristles on each 

 side projecting inwards and over the eyes; clypeus bright brown; palpi like 

 C. pipiens, covered with black scales and black bristles; proboscis deep brown; 

 antennae deep brown, basal joint chestnut-brown, base of the second joint testaceous. 



Thorax deep brown, with narrow pale golden curved scales, which become paler 

 in front of the scutellum; scutellum ochraceous-brown, with narrow curved 

 scales and golden-brown border bristles; metanotum chestnut-brown; pleurae pale 

 ochraceous. 



Abdomen ochraceous, with deep brown scales and basal pale creamy bands curved 

 from side to side; with thin rather long border-bristles and numerous long lateral 

 brown hairs; venter pale ochraceous. 



Legs unhanded, brown; coxae and venter of femora pallid; a pale indistinct spot 

 at the apex of the femora and tibiae, especially noticeable on the apex of the hind 

 tibiae; hind metatarsus a little longer than the hind tibia; ungues equal and simple. 



Wings with venation differing from Culex pipiens, in that the base of the first 

 sub-marginal cell is much nearer the apex of the wing than the junction of the sub- 

 costal and costal. 



Length. 5 mm. 



Habitat. Sambalpur, Central Provinces, India (Murphy) (99). 



Observations. Very like C. pipiens, but differing in wing venation and in the 

 form of the head scales, which are smaller in this species and in the larger thoracic 

 scales. 



Original, Description of Culex fouchowensis: 



Thorax dark brown, with narrow curved dull golden scales. Abdomen deep brown, 

 almost black, with basal dull white bands. Legs unhanded, dark brown; hind 

 metatarsus much longer than the hind tibia. Wings with brown scales, the lateral 

 ones linear and very dense, venation as in fatigans. Border-bristles of abdominal 

 segments alternately long and short. Ungues of the female equal and simple. 



$. Head dark brown, with narrow golden curved scales in the middle, becoming 

 paler at the sides, which are covered with flat white scales, a narrow-white-scaled 

 border surrounds the eyes, on each side of the occiput is a patch of black upright 

 forked bristles and some ochraceous ones between; clypeus, palpi, antennae and 

 proboscis deep brown, the antennae with deep brown basal joint and pale pubescence; 

 palpi short. 



Thorax deep brown, covered with short, scattered, very narrow curved golden- 

 brow^n scales, most dense and rather brighter on the anterior border of the meso-
