This large form, resembling faceta somewhat in its markings, 

 though differing in other respects, was recorded from Nebraska by 

 Uhler in 1876 {Bull. U. S. Geo!. Geog. Snrv. Terr., No. 5, ser. 2, 

 p. 21). The only addition to this record is a single male taken at 

 West Point in October, 1884, by L. Bruner. The species appears 

 to be nowhere common.
