Butterfly—Expanse of wings inches, 55-75 mm. Ground color pale fulvous, but little obscured with fuscous at base; a heavy black border at base; at least heavier than in nevadensis; lighter buff than nevadensis, under side of hind wings with large silver spots, olive brown color; the olivaceous of the wings encroaches on the marginal band. It may be known by its large size, by the long and pointed fore wings, and by the great size of the silver spots that ornament its under side. Distribution—According to Holland the species is not uncommon in Montana and Colorado. In Montana it has been taken by Wiley at Miles City, Douglass at New Chicago, and Fish Creek. Collected by Coues in 1874 on Chief Mountain. Remarks—Attention was called in the introduction to specimens identified by Edwards. One specimen sent by Wiley and another by Elrod from Miles City in different years were identified respectively as nevadensis and edwardsii. When placed side by side they are indis- tinguishable either in size or markings. Larger specimens from low ele- vation are likely to be called edwardsii, smaller ones from higher eleva- tion nevadensis. We believe that experiments in breeding will show the two species to Ije Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original University of Montana (Missoula); University of Montana (Missoula).
