thorax and body brown above. Abdomen and palpi white. Antennae 

 black above, whitish tipped with red l^elow. This species was taken at 

 Glencoe, Nebraska, upon high rolling prairie, from the first to the middle 

 of September. 



The above is the original description, copied from Canadian Ento- 

 mologist, Vol. VI, No. 3. 



Distribution The Western plains, Utah and Nebraska,, according to 

 Dyar. Given in "List of Butterflies taken by H. K. Morrison in Dakota 

 and Montana, 1881," in Canadian Entomologist, Vol. XIV, 1882. We 

 cannot tell from this list whether it was taken on the plains of Dakota or 

 Montana. 



THE WOODLAND SKIPPER, Thymencus sylvanoides, Boisduval. 



Butterfly Expanse, 1.25 to 1.34 inches, 31 to 34 mm. 



Male, upper side fulvous, darker at outer edge; a black stigma, large; 

 several (three) light spots near outer angle, beyond stigma. Female, 

 upper side with less fulvous, the wings prevalently fuscus, and the red 

 color reduced to a spot at the end of the cell; a median band of fulvous 

 spots on both wings. On the under side in both sexes the wings are 

 quite pale gray, with the costa near the base and the cell of the primaries 

 reddish. The primaries at the base near the inner margin are blac. The 

 spots on the under side reappear, but are pale and faint. This is to be 

 expected in the state, but we nave not seen the species among the col- 

 lections. 



Early Stages Unknown. 



Distribution The species ranges along the Pacific coast from British 

 Columbia to California, and eastward to Colorado. 

 Genus OCHLODES, Scudder. 

 THE INDIAN SKIPPER, Ochlodes sassacus Harris. Fig. 115.

 cell and along the border, the base dusky. A black, oblique stigma or 

 sex-mark below the cell. 



Under side pale fulvous, the posterior part fuscus; the five sub- 

 terminal spots of the upper surface repeated, a spot at the end of the cell, 

 a large triangular patch, with dentate outline, all yellowish white. The 

 hind wings have a sub-terminal band of six whitish spots across the 

 anterior two-third of the wing, and a spot at the end of the cell.
