THE COMMON SKIPPERS 



Persius's Dusky-wing 

 Tlianaos persius (Than'a-os per'si-us) 

 Plate XLV, Fig. 3 

 The wings are dark brown above with a row of small white 

 spots just before the apex of the fore wings and a single one in 

 cell M 3 , as in the preceding species. On the fore wings there 

 is a transverse pale band just beyond the middle of the wings, 

 but this band is not as well defined as in the precedingspecies. 

 Expanse of wings from one and two-tenths to one and four- 

 tenths inches. 



This skipper is found over a large part of the 

 United States. The larva feeds on willow and 

 poplar. 



Martial's Dusky-wing 



Thanaos martialis (Than'a-os mar-ti-a'lis) 



Plate XLV, Fig. 5 



The wings are brown above, conspicuously marked with 



spots of a darker shade ; the spots are well defined and give 



the wings a checkered appearance. There is a row of small 



white spots just before the apex of the fore wing, one in cell 



M , and one more or less distinct in cell R + M. 



This species differs from the following, which it most 

 closely resembles of all our Eastern species, by its smaller size 

 and the more strongly contrasting colors. Expanse of wings 

 about one and one-fourth inches. 



This species is distributed throughout the 

 Atlantic States and westward to Colorado.
