Chelis sordida is a moth of the family Erebidae. It was described by James Halliday McDunnough in 1921. It is found in the mountains of Alberta and British Columbia and possibly Yukon and Alaska. The habitat consists of dry rocky alpine tundra.
The length of the forewings is 15–16 mm. Adults are on wing from July to mid-August.[1]
This species was formerly a member of the genus Holoarctia, but was moved to Chelis along with the other species of the genera Holoarctia, Neoarctia, and Hyperborea.
