A genus of world-wide distribution, especially in tropical and 
warm temperate regions, rare or absent in the North. The larvae 
are surface feeders, occurring mostly in ground pools of a perma- 
nent character, some in running water, and a few species restricted 
to tree holes or leaves of Bromeliaceae. The larvae are easily told 
by the short air tube. They le attached to the surface film. The 
adults fly principally in the dusk. Some species freely enter houses. 
The hibernation is as adult. Most of the species of Anopheles trans- 
mit malaria, and are consequently of great economic importance. 
The following subgenera, based on characters of the male genitalia, 
are suggested for the United States species:
