The other lines are all present, with the AM and PM lines doubled and filled with paler scales. HW darker brown with a pale fringe. Female genitalia bisaccate and the ovipositor lobes without flanges and covered with small conical setae apically; male with short saccular extensions curving away from the cucullus. The median band on the FW and the dark HW will usually identify this species.

The Seton Lake Dart is usually fairly easy to identify. Most specimens have a slightly more prominent median band than the one illustrated. It flies fairly early for a Euxoa. It has been taken along the river valleys of the Alberta plains, from Edmonton south to Writing-on-Stone Park on the Milk River, and in the foothills north to the Nordegg region. Although not listed by Bowman, specimens from Edmonton were found in his collection under the name quinquilinea incallida. Euxoa incallida is now a synonym of comosa lutulenta, a similar appearing species. However, females of comosa have flanges on the tip of the ovipositor lobes while setonia has none. The Bowman specimen examined is without flanges.
