376 LEPIDOPTERA. 



suppose that the insect has any home in these Islands or that 

 any other individual of the species has been taken here. It 

 is an insect of peculiar appearance, having very long narrow 

 fore wings, black brown, with the dorsal margin whitish, 

 shaded with reddish, and the orbicular and reniform stigmata 

 yellow or edged with yellow and placed far apart ; hind wings 

 pale brown. The female is devoid of the reddish colour 

 along the dorsal margin ; its ground colour is greyer and 

 stigmata whitish. Its home appears to be in Western 

 Siberia, whence it has been obtained in some numbers by the 

 Rev. N. F. Dobree, and its larva discovered feeding by day 

 upon Corydalis gigantca and Ujnlobium. Elsewhere it seems 

 to be always rare, or at any rate scarce ; yet is found in 

 Finland, Lapland, Northern Russia, Tartary, and widely 

 distributed in North America.]
