HOW TO KNOW THE BUTTERFLIES 



transverse row of spots beyond the middle of the fore wings. 

 A rather small species expanding less than one and one- 

 fifth inches. 



The species is distributed throughout the 

 United States east of the Rocky Mountains. The 

 larva feed on grasses. The common name was 

 probably suggested by the tawny patch along the 

 costal margin of the fore wings. 



The Yellow Spot 

 Politcs peckius (Po-li'tes peck'i-us) 

 Plate XLI, Fig. io, ii, 12 

 The upper surface of both fore and hind wings is dark 

 brown with a row of yellow spots beyond the middle of each, 

 and the costal border is more or less yellow. The male has 

 a velvety black brand which is sinuous and interrupted be- 

 fore the middle. Lower surface of the wings cinnamon brown, 

 with the markings of the upper surface repeated in yellow ; 

 on the hind wings there is a large central yellow patch cover- 

 ing more than half of the wing. This is a small species 

 expanding from seven-eighths inch to one inch. 



The species was named in honor of Professor 

 Peck, one time of Cambridge, Mass. The com- 

 mon name was suggested by the yellow spots on 

 the wings. The skipper is found in Canada and 

 in the Northern States, west to Kansas.
