A small genus of general distribution, the species more numerous 
in the Tropics. The larvae are peculiar in having the air tube 
adapted for piercing the vascular roots of certain aquatic plants, 
from which they get their supply of air. The eggs are deposited in 
rafts in swamps where suitable plants grow, and the young larvae 
descend to the roots, never coming to the surface again. 
The genus has been divided into subgenera on genitalic characters,® 
as follows:
