DURING THE EECENT ARCTIC EXPEDITION. 115 



Varies slightly, some examples having the darker central band 

 of the anterior wings distinct, whereas in some it is scarcely indi- 

 cated. The two from Upernavik are remarkable for being paler 

 (pale silky grey), with no trace of markings. In none are the 

 markings so sharply defined and distinct as indicated by Curtis in - 

 his figure (Appendix to E-oss's Second Voyage, pi. A. fig. 12). 

 That given by Packard (^Phalcenidce of North America, pi. viii. 

 fig, 20) is much better. 



In Capt. Feilden's collection there is also an empty puparium, 

 with the crippled moth that emerged from it. 



Larvae of a geometridous Moth are in Capt. Feilden's collec- 

 tion — one indicated as from lat. 82° 33', and others from the 

 stomach of a Tern, lat. 82° 27'. The full-grown larva appears very 

 large for this insect ; but still I am inclined to think these pertain 

 thereto, especially as no other Moth of this family was observed. 

 Dr. Bessels appears to have found the same larva at Polaris Bay. 



Not being satisfied as to the true position of the insect, I have 

 retained Kirby's generic name. Packard places it in Olaucopteryx, 

 Hiibner, as adopted by him. I submitted the larvae to Mr. 

 Buckler, so well-known for his investigations of the larvee of 

 British species ; and he is strongly of opinion that they are related 

 to those of the genus Coremia, of which he says they have the 

 characteristic markings. The perfect insect reminds one of the 

 genus Cheimatohia ; but there is no real relationship.

SCOPARIA GELIDA, n. Sp. 



Anterior wings very narrow and elongate, the costal margin 

 straight, the apex subacute, with very oblique apical margin. 

 Grround-colour smoky blackish, rather silky, sprinkled with white 

 scales ; the two transverse lines darker : first line inconspicuous, 

 oblique, slightly angulate ; second line distinct, oblique inwardly 

 on the costal margin, then forming a very sharp curve outwardly, 

 running inwardly almost longitudinally to within the level of the 

 reniform spot, and then continued almost straight to the inner 

 margin ; it is bordered outwardly by white scales rather more 

 densely placed than on the rest of the wing ; the orbicular and 

 reniform spots dark (like the lines), without pale centres ; the 

 orbicular small, placed halfway between the first line and the re- 

 niform spot ; the latter larger, scarcely forming a solid 8 ; the 

 claviform spot not indicated ; fringes pale greyish. Posterior wings
