A Monograph of Culicidae. 



This genus is founded on Coquillett's Culex trivittatus, which 

 resembles to some extent Howardina walkeri, Theobald. 



It is separated from Howardina by the fact that all the 

 scutellar scales are narrow-curved ones, whilst some of those of 

 Howardina are flat. 



The cephalic characters resemble those of Hulecoeteomyia, 

 Theobald, but the scutellar characters again separate the two 

 genera.
