My examples from Amurland do not differ from Chinese or Japanese

Distribution. North, Central, and Western China, Japan, Amurland, and

" Subsimilis S. macidato, Brem., alis fusco-nigris ; anfcicis cum duabus lineis punctorum alborum,

 blackish ; no trace of the angulated submarginal white streak common to P. maculatm : 

 fringe white, spotted with brown. Expanse of wings 1 inch 'S lines." {Butler, I. c.)
