Expands from 1*50 to 1‘70 in. Marginal fringes not variegated. 
Wings dull fulvous, black at the base, with the usual black spots, 
the central row being banded. Under side : Hind wings dull rusty 
brown ; near the base are some white patches, and there is a very 
distinct white discoidal spot in typical specimens ; external to this 
is a broad yellowish grey central band, with white zigzag borders ; 
along the hind margin is a row of conspicuous spots white or grey 
in colour, and having a lozenge or T-shape ; internal to this is a 
light streak, upon which is a row of black spots. PI. XLVIL, 6. 
This is the most conspicuous of the Polar Fritillaries, the milky- 
white markings of the under side being very striking in dark 
specimens, especially the marginal row of spots, which frequently 
have a distinct T-shape. It is a variable species, closely allied to 
its immediate congeners ; but attention to the above-mentioned 
points, and particularly to the presence of a ivhite discoidal spot, 
will assist the diagnosis. 
Time of Appeakance.— July. 
Habitat. — North Lapland, ? Iceland, Northern Siberia, 
Labrador, and Greenland. This species has probably been taken 
further north than any other butterfly, being reported as having 
been taken by Capt. Feilden at lat. 81° 52' N. 
Laeva, &c. — Unknown. 
In connection with the subject of Arctic butterflies, I quote 
the following passage from Mr. M‘Lachlan’s * report, already several 
times referred to (Journ. Linn. Soc., vol. xiv., p. 98, 1878): — 
“ Capt. Feilden, in answer to questions, gave me some valuable and 
interesting information on the habits of Lepidoptera in those 
latitudes. He informed me that, during the short period when 
'*■ This gentleman has, since these pages were written, kindly called my 
attention to an allusion in Markham’s ‘Polar Eeconnaissance,’ p. 351 (1881), 
concerning the occurrence in Novaya Zemlya of Ar(jtjnnis Improba, Butler. 
There are two specimens of this European butterfly in the British Museum 
(those originally alluded to by Markham). It is my intention to give a figure of 
it in a supplementary plate,
