THE LEPIDOPTERA-RHOPALOCERA OF HUDSON'S BAY. 99 



other, or from Grapta C- Album, Linn. The former species was 

 captured in May ; the latter in June, July, and August. 



Lyccena Lucia, Kirby. — This species reminds me very much 

 of our L. argiolus, and would appear also to be double-brooded, 

 one of the specimens having been captured as early as June 13th, 

 and another as late as September. 



CoUas Eurytheme, var. 



Colias Keeivaydin, Edwards.— Can scarcely be distinguished 

 from our well-known Colias Eclusa. The specimens sent me were 

 taken in August and September. 



The four species belonging to British genera, which have no 

 near allies in these islands, but are represented on the Continent, 

 are as follows, viz. : — 



Argynnis Lapponica, Esp., and A. Tarquinius, Curt.--The 

 Hudson's Bay form of the first species differs in no way from the 

 European ; and the second may probably be only a geographical 

 variety, hardly differentiated sufficiently to be termed a distinct 

 species. They appear in June. 



Argynnis Bellona, Fabr. — In the shape of its upper wings, 

 which are long and narrow, this is much further removed from 

 the European species of the genus Argynnis than any of those 

 above mentioned : it iias a peculiar vinous-coloured under 

 side to the secondary wings, and the silver spots are quite 

 absent. 



Papilio Glaucus, Linn., var. Turnus, Linn. — In Europe this 

 fine species is represented by P. Alexanor, which it much 

 resembles ; it is also very like P. Podalirius. In July it is found 

 commonly by Mr. Haydon ; but the melanic variety, the true 

 P. Glaucus, does not seem to occur. 



The American type of an European genus is Limenitis 

 Arthemis, Drury, var. lamina, Fab. ; the only European species 

 which this approaches is L. populi. This latter species appears 

 to stand midway between such European species as L. Sibylla, 

 Linn , L. Camilla, Wien. Verz., and the American form assumed 

 by the genus on that Continent. The four specimens received 

 very closely resemble in both sexes Edwards' figures of 

 L. lamina, Fab., in the second volume of the ' Butterflies of 

 North America.' 



All the species dealt with I regard as Arctic or Sub-Arctic 

 forms, standing on the same footing as the Arctic birds, and to
