The extremes iuc presented by tlie I^ahnKlor and Vancouver Island (.-xamides. 

 The Pacific-coast I'ornis iirc larjfcr, lilackcr, tlic fore winf^s more elon<;at('d 

 toward tlie apex than the eastern specimens, much as observed in ^ciiiinlliisd 

 dispunda (Walk.), in wliich the Labrador individuuls an; stunted, while 

 the west-coast (Vancouver Island) specimens are larifer. They are paler, 

 however, than the Labrador and New Enirland individuals. Tlie Colorado 

 F. prunafa \av. luguhrdla scarcely ditfers from the Oalifornian ami \'ancouver 

 Island ones. My Lal)rador individual (well |»reserved) has already lieeu 

 described. The Adirondack (Mount Marcy) one is very similar, but dilfers in 

 being of a peculiar reddish-brow n tint, especially along the costa and veins. 

 The outer line between the costa and median vein is angulated outw ard, instead 

 of curved regularly outward, as in Ihe Labrador example. The Adirondack 

 is very near the Labrador one, though a little browner along the veins. In 

 the Colorado and Pacific specimens, the outer line near the costa is scalloped 

 four or five times. The middle band of the fore wings is much darker than 

 the rest of the wing; the inner and outer portimis being much paler than in 

 the eastern examples. Expanse of wings of Colorado and \'ancouver Island 

 specimens, L43 inches; of Labrador aiul alpine. Eastern L'nited States, L25 

 inches. 



In the general style of markings, this siiecies closely resembles C. j>opu- 

 lata, as remarked by Moeschler. I do not much doubt but that both have 

 come from a common stock; luguhiata being perhaps originally derived 

 from a melanotic variety oi populata. 



There are, then, four Ibrms, or varieties, o^ pn/inita. viz: the normal /;;■«- 

 mato(fig. 47); and the vars. destinata (very vnswx pvuKala), lugubrata (fig. 48), 

 and nubllata (fig. 4G). 



Staudinger gives the following localities of the torm jniniatn: Central 



and Northern Euroj)e, excluding (?) the polar regions; Central and Northern 



Italy; Dalmatia; Ural Mountains ; Altai .\[ountaius ; Northern and Eastern 



Siberia.
