Tliis easily recognizable species may b(^ known by the uniformly black 

 wings, with the broad white band in the middle of both wings; the band vary- 

 ing much in width, and sometimes entirely wanting on the hinder pair. 



Compared w ith an Alaskan example, a Colorado one is larger, with the 

 white band on the hind wings three times as wide, thus leaving a narrow, 

 dark margin, and a liiint, dusky shade at the base of the wing. I had regarded 

 the Alaskan and Maine specimens as quite distinct, and tlie latter as distinct 

 from the Lalira(hir var. ohductatd; l)ut a Pacific-coast specimen, received 

 from Mr. Jann's Behrings, labeled "Kenay" (near Kodiak, Alaska), is inter- 

 mediate bet\\T'en vars. hodiakaia and ohJiictata. The Paciiic-coast individual 

 has the white band on the fore wings much bent, as in Maine specimens, 

 and the hind wings almost black, as in var. concordata ; the white line being 

 almost obsolete. The Labrador individuals are more stunted than the Maine 

 ones, but both have black hind wings: while the Pacific-coast and Colorado 

 examples are mncli whiter, with broader white bands. The Alaskan moth 

 closely resemldes Dupimclicrs figure. Thus tiie Pacific and Colorado forms 

 resemble the Einoix an much more than the New England and Labrador 

 examples. It inhal)ils Central Europe, Lapland, tln^, Ural and Altai Mount- 

 ains, and Amur. It is i (ported by Grote as having ))een collected by Ken- 

 uicott along the route from the IMackenzie Piver to Lake Athabasca.
