Generic Diagnosis of Adult: 



Palpi short in the female, generally long in the male, occasionally shorter, half 

 as long as the proboscis or even as short as those of the female. Antennal shaft 

 filiform, the joints subequal in the female, with basal whorls of rather sparse hairs 

 on the joints; all but last two joints shortened in the male, with a curved, raised 

 rim bearing the hair-whorls, which are long, dense, appearing plumose. Proboscis 

 varying in length, stout or slender, uniform or enlarged at apex, straight in the 

 male, more or less curved in the female. Prothoracic lobes well separated. Meso- 

 notum with rows of coarse setae on disk. Scutellum trilobate. Abdomen sub- 

 cylindrical, truncate at tip in the female, the cerci short and inconspicuous; slightly 

 or not at all expanded at the tip in the male, occasionally depressed, often with 

 dense lateral ciliation. Legs moderate; scraper of hind tibiae of not more than five 

 teeth; claws equal and simple in female, unequal and some of them toothed in male. 

 Wing of male generally narrower than that of the female, basal cross-vein remote 

 from anterior cross-vein, never incident. 



Generic Diagnosis of Larva: 



Head rounded, flattened; antennae large, usually with the tuft large and placed 

 beyond the middle, arising from a distinct notch. Air-tube usually over three times 

 as long as wide, rarely short, always with several scattered hair-tufts or single hairs, 

 rarely reduced to obsolescence; pecten present in two rows at base of tube. Lateral 

 comb of eighth abdominal segment of generally numerous scales in a row or patch. 

 Anal segment completely ringed by a chitinous band in last stage and with well- 

 developed ventral brush. Anal gills variously developed. 



Distribution throughout the world, except in the Arctic regions. 



The males have the claws of the front and middle legs large and unequal, 

 in the typical forms each with a long slender tooth near its middle. In many 

 forms the lesser claw of these legs appears to be simple, but close examination 

 will in most cases reveal a slender tooth inserted close to base on the inner side. 

 The male palpi in the more typical forms are acuminate and curved upward;
