 Hesperia Mingo, nov. sp. 



Male. Expands 1 inch. Upper side brown, much marked with 

 bright fulvous, which covers the central margin of primaries from the 

 base to near the end of the cell and back to the median nervure, ex-

 lique row of confluent spots extends from the costa to the inner mar- 

 gin, broken opposite the cell, two small spots ranging outside the line, 

 with a space between them and the costal spot; edge of inner margin 

 also fulvous. 



Secondaries have a similar row, or rather, one long spot across the 

 wing, and two spots in the disc and on costa; fringes fulvous. 



Under side pale-brown washed with fulvous, which last color prevails
