green hairs. The larvae feed upon both Leguminosae and 

 Cruciferae. In the South it is sometimes a pest in gardens, 

 cutting and rolling the leaves of beans, turnips, and cabbage, 

 and feeding within the rolls thus formed. It is found on 

 the Atlantic border from New York southward into Mexico. 



There are two common skippers which are nearly as 

 large as the two described above, but which have neither 

 the yellow band of the first nor the long tails of the second ; 

 neither do they have the brown spots characteristic of the 

 following genus. These two skippers belong to the genus 

 Thorybes. The wings are of an even dark brown ; the fore 

 wings are flecked with small or very small irregular white 

 spots, and the hind wings are crossed beneath by two rather 

 narrow, parallel, inconspicuous darker bands. These skippers 

 are distinguished as follows : 



The Northern Cloudy-wing, Thorybes pylades (Thor'y-bes 

 pyl'a-des). In this species the white spots on the fore wing 

 are usually mere points, although their number and size 

 vary. The species is found in nearly all parts of the United 

 States. The larva commonly feeds on clover. 



The Southern Cloudy-wing, Thorybes bathyllus (T. 

 ba-thyl'lus). In this species the white spots are larger 

 than in the preceding, almost forming a continuous band. 

 This skipper is widely distributed over the eastern United 

 States, except the more northern portions. 



To the genus Thanaos belong a large number of species 

 which on account of their dark colors have been named 

 Dusky-wings. These species resemble each other so closely 

 in markings that it is very difficult to separate them with- 

 out longer descriptions than we can 

 give here. The one following will 

 serve as an example.
