A Monograph of Culicidae. 
tropical climates, species having been recorded from N. and S. 
America, East and West Indies, Central Asia, India, Natal, 
Central Africa, and Australia. Specimens too denuded to 
identify have been sent from British Guiana and Zomba in 
British Central Africa. No less than six of the known species 
come from South America. The probability is that forest 
collecting would add many more species to this beautiful genus. 
Nothing whatever is known of the life-history of these insects 
as far as I can find out. 
At present the genus can only stand roughly, as I have had 
just enough material to find certain aberrations which may 
cause it to be considerably modified.
