chaetae, some golden at the base, the golden scales show some- 

 what linear arrangement ; scutellum brown with pale curved 

 scales and seven brown border-bristles to the mid lobe ; meta- 

 notum brown. 



Abdomen black with snowy-white basal bands, the apical 

 segment with two basal lateral snowy-white spots, border-bristles 

 and lateral hairs pale golden. 



Legs deep brown, femora pale at the base, knee spots pale ; 

 fore legs with a white band at the base of the first tarsal, mid 

 with white bands on second to fourth tarsals, that on the fourth 

 minute, the bands more pronounced on the hind legs and involving 

 both sides of the joints on all the legs ; ungues of fore and mid 

 legs equal and uniserrate, on the hind equal and simple. 



Wings rather short ; fork-cells short and the scales rather 

 dense, median vein scales broad, long and diverging ; first sub- 

 marginal cell a little longer and narrower than the second 

 posterior cell, its base a little nearer the apex of the wing, its 

 stem rather more than half the length of the cell ; stem of the 

 second posterior cell also about half the length of the cell ; 

 posterior cross-vein twice its own length distant from the mid. 



Length. — 4 to 4*5 mm. 



Habitat. — Osaka, Japan.

 somewhat aberrant from the genus Culex, but I can see nothing 

 to exclude it unless it is placed on account of the rather dense 

 wing scales with C. taeniorhyncltus in the genus Culiselsa, Felt.
