The arctic species Dasyuris polata , described by Duponchel (1830: 402; Pl. 199, Fig. 4) from northern Europe, has been known from America since early times. The species is notoriously variable; until recently, however, it has not been possible to assess the geographic components of its variation. There are now, largely as a product of the Northern Insect Survey, excellent series of D. polata in the Canadian National Collection. Through the kindness of correspondents I have been able to supplement these series by borrowing material of certain non-Canadian forms, and it has become evident that D. polata has striking geographic variation in North America.
