 the base of the last two segments, last two segments with long brown hairs on each side ; 

 antennse banded brown and white, plume hairs very fine and brown. 



Thorax as in the ?. Abdomen black with traces of yellow basal bands (in some

Wings (Text-fig. 6 a) with rather long fork-cells, the scales broader than in the ? , 

 first fork-cell much longer and narrower than the second fork-cell, its stem one-fourth the 

 length of the cell, its base considerably nearer the base of the wing, stem of the second 

 fork-cell about two-thirds the length of the cell, posterior cross-vein about the same length 

 as the mid and about twice its own length distant from it. 



Length. 4'5 mm. 



Localities. Seychelles: Mah^ and Silhouette, 1908 — 9 (H. Scott). 



Observations. Described from a series of 41 $s and 3 ^s. 



The following notes sent with them : — " Mahe, Cascade Estate, about 1000 feet, 

 calmer and wetter season X. 1908 and XL 1909. Come into house at evening, especially 

 when lamps are lighted"; " Mah^ near Morne Blanc, 1000 feet X. — XL 1908, come into 

 house when lamp is lighted and bite"; "Silhouette forests about 1000 feet and more, 

 trade wind season VIII. — IX. 1908, come in evening when there is lamplight and bite; 

 on very windy evenings much less numerous." 



There is not much variation in the specimens, but some do not show the thoracic 

 ornamentation as clearly as others. Its marked thoracic appearance and unhanded 

 abdomen in the female will at once separate it from other Culices. The male shows 

 abdominal banding, but again the thoracic ornamentation is very marked.
