This interesting species differs from all the eastern ibrnis l)y its heavily- 

 ciliated antennae, its bright brick-red wings, whieli are pare odireous beneath. 

 It is closely allied to IIk; Californian A. ruhro/ineata, Ijnt rather darkei-, with 

 darker lines, and the body is rather more hairy than in th(! Californian species. 

 It (liflTers, in flict, from the Californian rubroHneata in those characters which 

 Arctic species are apt to have, viz, a tendency to melanism, a more hairv 

 body, and heavily-ciliated antenna'.
