PECK'S SKIPPER. 315 



ers ; fore wings in the female without the tawny front edge 

 and black line ; hind wings, in both sexes, with a central, 

 curved, tawny-yellow band ; wings beneath bright red- 

 brown ; the first pair blackish, from the middle to the inner 

 edge, and spotted as on the upper side ; hind wings with a 

 yellow dot in the middle, and a curved row of seven bright 

 yellow spots behind it. 



Expands from 1 2 V to lj inch. 



This very distinct and strongly marked skipper does not

 have dedicated the species. The females I have taken in the

Dark brown above ; all the wings with a tawny-yellow 

 spot occupying the greater part of the middle of each, and

 on the upper side of the fore wings ; and on the hind wings 

 seven small, square, pale yellow spots, namely, one before the 

 middle and the others in pairs behind it. 



Expands 1J inch. 



Of this skipper I have seen only the female, which was 

 taken in Cambridge in the month of June. Its upper side 

 is very much like that of the Hobomok skipper, but it differs

 seems not to have been described before. I have therefore 

 given it, as a new species, the name of an Indian warrior. 



Hesperia Peckius, Kirby. Peck's Skipper. (Fig. ,139.) 



Dark brown above ; fore wings with a row of contiguous 

 tawny-yellow spots, extending from the middle of the inner 

 margin towards the tip, where the spots are more distant, 

 and a tawny line from the base to the middle, behind which,
