HOW TO KNOW THE BUTTERFLIES 



Juvenal's Dusky-wing 



Thanaos juvenalis (Than'a-os ju-ve-na'lis) 



Plate XLV, Fig. 6 



The wings are dark brown marked with brown spots of a 

 darker shade, and with small white spots on the fore wings. 

 This insect can be distinguished from the preceding species, 

 which it most closely resembles of all our Eastern species, by 

 its larger size, and the fact that the checkered appearance of 

 the wings is less obvious. Expanse of wings about one and 

 one-half inches. 



It has been found throughout the eastern 

 United States except perhaps the Northwest. 

 The larva feeds on oak. 



The Tessellate Skipper 



Hespcria tessellata (Hes-pe'ri-a tes-sel-la'ta) 



Plate XLV, Fig. 7 



Wings blackish brown largely checkered with white ; more 

 than one-half of the outer two-thirds of both and hind wings 

 being white. In this species the white spots in the band just 

 beyond the middle of the fore wings are much broader than 

 high. Expanse of wings about one and two-tenths inches. 



This insect is found throughout nearly the 

 whole United States. The larva feeds on holly- 

 hocks and Indian mallow.
