 joints dark, testaceous, the basal joint with white scales internally ; clypeus 

 brown. Thorax brownish-black, with rich reddish-brown narrow-curved 

 scales, and a few broader gray ones at the sides in front, and some 

 arranged in lines behind the mesonotum, on its surface are two small pale 

 spots, two of the posterior white lines being continued back from them, two 

 short, broader ones are situated in front of the bare space before the scutel- 

 lum; the reddish-brown scales have a linear arrangement, due to two promi-

 gray to dull ochraceous, pale ventrally, with a row of white spots 

 above, almost forming a white line ; apex with a white spot ; tibife also 

 with a row of white spots, forming almost a line, apex white ; fore and 

 mid metatarsi and tarsi with narrow apical and basal yellowish bands, 

 except the last tarsal segment ; in the hind legs the metatarsi and tarsi 

 have broad, almost white bands, the last tarsal in some specimens being

 densely scaled with typical brown Culex scales ; those at the base of the 

 third long vein thicker, forming a small, rather obscure, dark spot ; first 

 submarginal cell longer and considerably narrower than the second 

 posterior cell, its base slightly nearer the base of the wing, its stem about 

 one-third of the length of the cell ; stem of the second posterior cell about 

 two-thirds the length of the cell ; posterior cross-vein not quite its own 

 length distant from the mid cross-vein ; fringe dark brown ; halteres

 penultimate, the penultimate slightly shorter than the apical ; the last two 

 joints with long brown hairs on each side, also on one side, of the apex of 

 ante-penultimate joint ; there is a narrow pale band at the base of the 

 last two joints and also near the base of the long ante-penultimate joint ;
