Examination of the genitalia shows that typical albertina posesses 

 a strong fold below the corona practically separating this structure 

 and the tip of the valve from the remaining portion; the present 

 species practically lacks this fold, only a vestige of it appearing along 

 the ventral edge of the valve. 



It is not impossible that hanhami will ultimately prove to be a 

 race of hillii a single female specimen of the latter, a topotype, labeled 

 "Lewis Co., N. Y., July 31, 7^, W. W. Hill, Coll." being in the Barnes 

 Collection. Judging from this single specimen, which agrees well with 

 Hampson's figure, (1908, Cat. Lep. Phal. B. M., VII, 413, pi. CXVIII, 

 f. 19), hanhami is a distinct species, heavier, larger, its wings longer 

 and less trigonate, the contrasts between the maculation and the 

 ground color not so pronounced, the under side much less heavily 

 suffused with blackish. 



Type locality: Duncans, Vancouver Island.

 pleasure in naming the species.
