MOSQUITOS OR CULICIDAE OP NEW YORK STATE 271 



CULICINAE 



This subfamily includes by far the largest number of species, 

 and its representatives are the ones most commonly met with 

 about h'ouses and in woods. The females have short palpi, while 

 they are long in the male. We have in this subfamily several 

 genera, such as Janthinosoma, which latter agrees closely in all 

 structural details with Culex except for the densely scaled legs 

 and is separated from other genera possessing this character by 

 the venation of the wings, which is the same as in Culex, and 

 by the broad, spindle-shaped scales of the head. This subfamily 

 also includes among native forms the giant Psor^ophora 

 c i 1 i a t a Abr., a species with densely scaled legs, and Stegomyia, 

 which is of particular interest because certain species are known 

 agents in disseminating yellow fever, A number of other genera 

 have been separated on minor structural differences.
