Genus Culex. 425 



" $ . Head dark, covered with light ochraceous, almost cream-coloured 

 curved, and light fawn-coloured forked scales on the occiput, with white 

 flat opalescent ones at the sides and a rim around the eyes; antennae 

 light brown, pubescence and verticels the same ; palpi light brown ; 

 proboscis light brown ; eyes dark blue. 



Thorax very light with two rather broad light-brown sub-median 

 lines and a light greenish-brown tinge, covered with a frosty bloom much 

 like that found on Anopheles, sparsely covered with very small hair-like 

 golden scales. Scutellum light brown with similar scales; metanotum 

 almost white, pleurae testaceous, a soft green-blue. The whole thorax 

 has a greenish tinge and a general translucent appearance. Abdomen 

 dark green sparsely covered with very thin white opalescent flat scales 

 and light brown hairs ; ventrally much the same. 



Legs : coxae and trochanters coloured like pleurae, femora light fawn- 

 coloured dorsally, white ventrally ; tibiae much the same ; all the tarsal 

 segments rather darker — a light brown— the scales are all small and on 

 these segments give golden reflections. Ungues small, simple and equal. 



Wings covered with small fawn-coloured scales ; first sub-marginal a 

 little longer and nearly the same width as the second posterior, the stems 

 of both about two-thirds the length of the cells ; the supernumerary cross- 

 vein the same length as the mid and about two and a half times its length 

 distant. Halteres, light stem, fawn-coloured knob. The third long vein 

 is extended into the basal cells by an incrassation nearly as heavy as that 

 found in the Desvoideae. 



Length. — 3 to 3*5 mm. 



$ . Differs from £ very slightly. Antennae a soft light brown and 

 the tufts of the palpi are small and of the same general fawn colour ; the 

 thorax frequently lacks the two light sub-median lines, and is perhaps 

 lighter. Ungues of fore and mid legs slightly uneven, the larger bearing 

 a large tooth about midway. 



Habitat. — Oras, Samar, Philippine Islands. 



Time of capture. — August (6th) (Miss Ludlow)." 



Observations. — This species described by Miss Ludlow is 

 clearly very distinct. It comes nearest my Culex viridis, and 

 perhaps, as in that species, the green colour may be due to green 

 algae in the body.

Head brown, with dull yellowish scales in the middle, a black 

 patch on each side and grey laterally. Male palpi deep brown, 

 with a narrow pale band at the base of each of the two apical 

 segments and a broader pale one on the ante-penultimate seg- 

 ment. Proboscis unbanded. Thorax deep brown with paler
