{"abstract":"We, the U.S. Fish and Wildlife Service, propose to list the Mount Charleston blue butterfly (Plebejus shasta charlestonensis) as an endangered species under the Endangered Species Act of 1973, as amended (Act). We also propose to list the lupine blue butterfly (Plebejus lupini texanus), Reakirt's blue butterfly (Echinargus isola), Spring Mountains icarioides blue butterfly (Plebejus icarioides austinorum), and the two Spring Mountains dark blue butterflies (Euphilotes ancilla cryptica and E. a. purpura) as threatened due to similarity of appearance to the Mount Charleston blue, with a special rule pursuant to section 4(d) of the Act. We solicit additional data, information, and comments that may assist us in making a final decision on this proposed action. In addition, we propose to make nonsubstantive, administrative changes to a previously published listing and special rule regarding five other butterflies to correct some inadvertent errors and to make these two special rules more consistent.","action":"Proposed rule.","agencies":[{"raw_name":"DEPARTMENT OF THE INTERIOR","name":"Interior Department","id":253,"url":"https://www.federalregister.gov/agencies/interior-department","json_url":"https://www.federalregister.gov/api/v1/agencies/253","parent_id":null,"slug":"interior-department"},{"raw_name":"Fish and Wildlife Service","name":"Fish and Wildlife Service","id":197,"url":"https://www.federalregister.gov/agencies/fish-and-wildlife-service","json_url":"https://www.federalregister.gov/api/v1/agencies/197","parent_id":253,"slug":"fish-and-wildlife-service"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2012/09/27/2012-23747.html","cfr_references":[{"chapter":null,"citation_url":null,"part":17,"title":50}],"citation":"77 FR 59518","comment_url":null,"comments_close_on":"2012-11-26","correction_of":null,"corrections":[],"dates":"We will accept comments received or postmarked on or before November 26, 2012.
