knobbed antennae, while hylax differs in the shape of the wings and in 

 wanting the discal stigma in the male. 

 Distribution. Holarctic. 



8. Genus Erynnis. 



Erynnis, Schrank, Fauna Boica, ii. I, p. 157 (1801). 



Type, comma, Linn. 



Ocytes, Scudd. Syst. Rev. p. 55 (1872). Type, metea, Scudd. 



Antennae short, less than half the length of costa ; club short, 

 robust, terminal crook exceedingly minute. Palpi as in ILilepldla. 

 Neuration as in Hylephila except that vein 2 of the fore wing is 

 much nearer to the base of the wing in the male, and vein 7 of the 

 hind wing is slightly nearer the base of the wing in both sexes ; the 

 stigma on the fore wing is very similar to that of FI;//epki/u, except 

 that it entirely fills the angle at the bifurcation of vein 2, while in 

 Hi/lephila the discal stigma crosses the interspace beyond the origin 

 of vein 2.

9. Genus Anthomaster. 

 Anthomaster, Scudd. Syst. Rev. p. 57 (1872). 



Type, leonardus, Harr. 

 This genus does not differ appreciably from Erynnis in neuration 

 or the stigma of the male, while the sexual organs show a remark- 

 able similarity. The differences given by Scudder are very slight, 

 and as far as the autennse are concerned are absolutely imperceptible, 

 and if it had not been separated by the greatest living authority 

 on this group, it would have been unhesitatingly sunk in this paper 

 as identical with Erynnis.

10. Genus Ochlodes. 



OcUodes, Scudd. Syst. Rev. p. 57 (1872), Type, nemorum, Boisd. 



Antennae short ; club stout, rather elongate, with a minute ter- 

 minal crook. Palpi as in HylepMla. 



Neuration as in HylepMla, except that vein 7 of the hind wing is 

 nearer to the base of the wing. 



Male with a linear discal streak on fore wing, bordered on both 

 sides with differently formed, loosely compacted scales.
