The mosquitos are small to medium sized flies, characterized 

 by the projecting proboscis (sometimes lobed) and by the plu- 

 mose antennae of the male. The head is small, round; eyes 

 reniform, and ocelli are wanting. The antennae are threadlike, 

 composed of 15 joints, counting the disklike base; the first 

 joint is thick, the following joints small, round and beset with 

 whorls of hairs, forming in the male a long, dense plumosity; 

 the last two joints in the male are slender and bare, or nearly 

 80. The thorax is ovate, arched, but not projecting over the 

 head, without transverse suture, scutellum narrow; metanotum 

 jHrched. Abdomen long and narrow, somewhat flattened, com- 

 posed of eight segments; male genitalia prominent, ovipositor 

 short, legs long and slender, the coxae not elongated; the tarsi 

 long. AVings long and narrow, with numerous veins; the hind 

 margin fringed, the costal vein extending all around the wing, 

 iind ill all known American forms the veins are covered with 

 scales. Venation as in the figures. 



The larvae are known as " wrigglers." Tlie head is fully 

 differentiated and usually has eyes; the mouth is usually thickly
