 see, very dark, and this seems to be its most prominent charac- 

 teristic.

 Bremneri is the darkest of all our Argynnids on the underside, 

 the males being almost black near the center of the wing. It flies 

 on the low lands along the sea coast, and never, so far as I know, 

 at any considerable height on the hills, nor at a great distance 

 from the ocean.

I have taken in that locality a variety, indistinguishable on the 

 upper side, but which on the underside of hind wings is very 

 different, the white or buff spots being almost obliterated, and 

 the whole wing suffused with a sordid rusty color. This form I 

 tentatively call Sordida. It bears the same relation to Bremneri 

 that Hydaspe does to Zerene ; each variety being a rusty or cin- 

 namon-colored variety of the parent species, we may call them. 

 The figure of Sordida was crowded out at the last moment by 

 other figures which could not possibly be left out.

 Zerene is one of the prominent species of mountain Argynnids 



of Northern California, being very abundant everywhere in the 

 mountains of California and Oregon, and extending south in the 

 high Sierras to Lake Tahoe, which locality seems to be its southern 

 limit. The spots on the underside of hind wing are large, and buff 

 in color, and are not silvered in either sex, as a rule.
