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 hand ; 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 3 V to If inch. 
This very distinct and strongly marked skipper does not

Hesperia Sassacus. Sassacus Skipper. 
Dark brown above ; all the wings with a tawny-yellow 
spot occupying the greater part of the middle of each, and 
with two or three little detached spots of the same color near

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.

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

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

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