Metamorphosis M. culiciformis a De Geer descripta ; larvae 
in aqua vitam degunt; victus rapax. 
The species are of medium size or perhaps rather small, 
like the species of Corethra; in habit, although they come 
very near the last-named midges, they nevertheless in some 
respects more resemble the species of Culex than the true 
midges. Nearly the same may be said of the other genera 
here under consideration ; the larvee of Culew and Mochlonya 
in habit come nearer to each other than the larvae of Woch- 
lonyx and Corethra, but the relation is reversed when we take 
into consideration the essential characters.
