with juniper- trees and scrub-pines. It is about 20 miles east of south 

 of Mokiak Pass. 



Neominois dionysus^ nov. sp. — Differs from N. ridingsii, to which it is 

 closely allied, by its larger size, its more cinereous tints, and by the 

 much more produced serrations of the margins of all the banded mark- 

 ings of the hind wings. In most specimens, this latter feature is much 

 more conspicuous below than above, and is generally more noticeable 

 than elsewhere in the interspace beyond the cell, the tooth of the black 

 line which crosses the middle of the wing sometimes extending one-third 

 the distance to the margin of the wing. Where specimens of the two 

 species approach each other in the sharpness and length of the serra- 

 tions, this species can always be distinguished by its larger size, lighter 

 tone, and the lesser contrast of its darker and paler markings. The 

 lower median interspace of the hind wings bears a small, oval, longi- 

 tudinal spot on the upper surface next the outer limit of the broad, 

 subraarginal, pale band, smaller and even obsolete in the male. The 

 same spot occasionally appears, but less conspicuously, in the female 

 of N. ridingsii. Although Nevada specimens of the latter appear to 

 be larger than those from Colorado (c/. Edwards's description of Sat. 

 stretcMi), iu so far approaching this species, Satyrtis stretchii appears to 

 be a true synonym of JV. ridingsii, being in other respects no closer to 

 the species here separated.

Argynnis coronis Behr. — A single female was taken by Dr. Palmer 

 on the Beaver Mountains, July 18-20, which differs from specimens sent 

 me bj^ Mr. W. H. Edwards, under this name, in the darker color of the 

 upper surface of the wings, the brown becoming nearly black and the 

 fulvous deepening to tawny, and in its smaller size, since it only expands
