20. Body glabrous or lightly granular 26 



26. Air tube regularly tapered, the tip not widened 28 



28. Both head hairs triple or multiple 29 



29. Lateral abdominal hairs in twos after the second segment; body

Description of Female, MAia;, and Laeva of Culex lamentatoe:

 bars at tips of segments and a row of sub-basal black spots; a row of whitish 

 hairs at tip of each segment dorsally. 



Wings moderate, hyaline; petiole of second marginal cell about one-third as 

 long as its cell, that of second posterior cell a little shorter than its cell ; basal 

 cross- vein four times its own length distant from anterior cross-vein; scales 

 blackish brown, outstanding one broadly linear, very dense on forks of second 

 vein. Halteres whitish, dark at tip. 



Legs moderate, femora white beneath almost to tip; tibiae white at apices,
