The above description is taken from a single male example sent us by Morrison 

 under the name of Pamjphila Colorado, Scudder, which is now generally treated, like 

 several other North- American forms, as nothing more than a variety of E. comma (Linn.). 

 We have nine specimens from North America from Mr. Strecker named P. Colorado, 

 with none of which does it quite agree. Compared with Mr. Scudder's figures of the 

 North-American forms of this species (Mem. Bost. Soc. 1874, t. 10), it seems to come 

 nearest to E. juba and E. nevada. It is unnecessary to quote the lengthy synonymy 

 here.

Morrison has sent us a single female under this name which agrees very well with a 

 male from Colorado in our collection ; from this latter insect our description of that 

 sex is taken. E. morrisoni is closely allied to E. comma, but may at once be 

 distinguished from it by the angulated fulvous submarginal band on both wings above 

 and by the similarly shaped white band on the secondaries beneath. 



Our fi ures are taken from the Colorado male. 



IV. Antennas short, with a stout club, terminating in a short crook ; terminal joint of 

 the palpi short ; hind tibiae with two pairs of spurs ; primaries of the male with a 

 greatly developed brand.

The type of this genus is Hesperia huron, Edw. (=11. campestris, Boisd.), and it also 

 includes H. ctrnaxa, Hew. (=H. mesogramma, Poey). It is separable from Thymelicus 

 by the great development of the brand on the primaries in the males : in this sex the 

 neuration is modified to make room for it, the cell being very narrow from the base to 

 beyond the middle, the second median segment arched forward and much longer than 

 in the female, and the first and second median branches strongly curved towards the 

 base. The brand of the male consists of a large, broad, oblique, closely compacted 

 mass of small dull greyish scales, filling the angle between the second median segment 

 and the first median branch, and extending some distance below the latter, this being
