242 Mr. H. J. Elwes on a 



aberration, and T cannot say positively whether it is 

 polaris or char idea, though the size and the shape of the 

 wings indicate the latter species.

 Fapilio frigga, Thunberg, t.c, p. 33. 



Argynnis improha, Butler, Ent. Mo. Mag. XIII, 

 p. 206 (1877). 



Several from the Barren Grounds and one from Point 

 Epworth are like the type, and show but little variation.

Papilio orhitidus, Esper, Schmett. I, 2, PI. CXII, fig.

 Zycmna franki inii, Curtis, t. c, p. 69, PI. A, figs. 8, 9. 



A pair from the Barren Grounds are not so distinct 

 from the Arctic form found in Europe, var. ccqioilina, Stgr., 

 = aquilo, Bdv., as those from Labrador, and are perhaps 

 nearer to those I have taken in the Rocky Mountains 

 near Laggan. 



12. Oolias heel a. 



C. hecla, Lefebvre, Ann. Soc. Ent. Fr., 1836, p. 383, 

 PL IX, B, figs. 3-6. 



Four males and three females from the Barren Grounds, 

 114° W., 67 40 N., 13-16, vii. Agreeing well with other 

 specimens from Arctic America, some of which were 

 called glacialis by McLachlan. 



Staudinger now catalogues the Lapland form as var. 

 siditelnia, Anriv. The specimens in Mr. Hanbury's collection 

 differ inter se to a remarkable extent in the colour of the 

 borders and discal spots of the wings above. 



13. Colias hoothii. (Plate IX, figs. 1-4 ^,5 $.) 

 G. hoothii, Curtis, t. c., p. 65, PI. A, figs. 3-5. 



This was represented by several fresh specimens, which 

 enable me to confirm the opinion formed on very in- 

 sufficient previous knowledge, that it is a species perfectly 

 distinct from the last. The variation in this species is so 

 great that I have had to figure five specimens to give a 

 fair idea of it ; some of them would be supposed by their 

 markings to be females, but though the abdomens are
