segments, the fifth sometimes very inconspicuous ; basal lateral white 

 spots most prominent on the apical segments ; venter clothed with 

 creamy yellow scales; border-bristles of the dorsum pale golden. 

 Legs deep brown, except the coxfe and venter of the femora, which 

 are grey to creamy yellow; femora, tibife, and hind metatarsi with 

 black bristles ; hind metatarsi very nearly as long as the hind tibife ; 

 fore and mid ungues equal, uniserrated ; hind equal and simple. 

 Wings clothed with typical brown Culex scales; fork-cells rather 

 short ; first submarginal cell very slightly longer, but narrower than 

 the second posterior cell, its stem about as long as the cell, its base 

 about level with the base of the second posterior cell, if anything 

 slightly nearer the apex ; stem of the sec6nd posterior cell not quite 

 as long as the cell ; posterior cross-vein very short, about twice its 

 own length distant from the mid; a pale spot at the base of the wing; 

 halteres testaceous. Length 4 to 4*5 mm.

Time of capture. August. 



Observations. — Described from a series of females taken by 

 Dr. Grabham. They are very distinct, small, thick-set mos- 

 quitoes, easily told by the thoracic adornment, the two dark 

 spots on the front of the mesothorax being very characteristic ; 

 their unhanded legs at once separate them from Culex secutor, 

 Theob., or C. janitor, Theob., and they are of much stouter 

 build. When alive they can easily be identified by the character 

 noticed by Dr. Grabham, of carrying their hind legs twisted 

 right forward over their head, when settled, after the manner of 

 Wycomyias. There is some variation in the venation. Some 

 specimens show the base of the first submarginal cell slightly 

 nearest the apex, and the posterior cross-vein as long as the mid 

 cross-vein, and about its own length distant from it. In others 

 the basal abdominal banding is very faint; in one there is a 

 trace of an additional basal abdominal band.

Head metallic violet, white between the eyes in front ; palpi and 

 proboscis black ; antennae pale brown. Thorax metallic green ; pleuraa 

 snowy white. Abdomen bright metalhc violet, with three prominent 

 and one faint silvery white basal bands and white lateral spots. Legs

? . Head clothed with flat metallic violet scales, except a patch 

 between the eyes, which are white, and at the sides, where they are 

 grey and black ; black bristles project over the eyes, and there is a 

 trace of a narrow pale border surrounding them ; clypeus with a frosty 

 sheen ; palpi black ; proboscis black, curved upwards, nearly as long 

 as the whole body ; antennse pale brown, basal segments deep brown,
