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. 1 hese skippers 
are distinguished as follows :— 
The Northern Cloudy-wing, Thorybespylades (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. 
Martial's Dusky-wing, Thanaos 
martialis (Than'a-os mar-ti-a'lis).— 
The wings are grayish brown with Fig. 453,— Thanaos martialis.
