Guenee, in the work cited above, refers the Arctia cervini, which 

 is very closely allied to A. Quenselii, to the genus Nemeophila of 

 Stephens, and then goes so far in the subdivision of this " genus " 

 (Nemeophila) as to eliminate from it the genus CJnonophila, in 

 which he includes Cliionophila plantaginis (Linn.), C. Quenselii (Pay- 

 kull), C. glaplujra (Eversm.), and C. virguncula (Kirby). 



We have two males from Okak, together with two females from the 

 alpine summits of the White Mountains of New Hampshire. One of 

 the latter was reared from the pupa by the late Mr. C. A. ShurtlelF, 

 and taken on Mount Washington, while the other was reared by my- 

 self from a larva found by Mr. Scudder on the summit of Mount 

 Madison. None of the specimens arc alike, all presenting marked va- 

 riations. The (? specimens from Okak are much smaller than those 

 (?) from the White Mountains, the abdomen is blacker, and the yel- 

 lowish white lines are not visible from above on the abdomen ; but 

 these seem to be but sexual differences. In one of the Okak speci- 

 mens the hind wings are entirely black, with the darker diffuse discal 

 spot unusually distinct ; but another much rubbed specimen presents 

 indications of being streaked on the hind wings like one of the White 

 Mountain (?) specimens. The two specimens from Okak differ as 

 much from one another as the two White Mountain moths ; the two 

 outer subcostal square patches in one being united, and in the other, 

 separated. One of the White Mountain moths differs from all the 

 others of both sexes, in having a transverse yellow band crossing the 

 inner third of the wing, thus breaking the surface up into black 

 spots, which seems to be an unusual variation. The front of the head, 

 also, is entirely black, where in all the others it is yellowish with a 

 central black spot varying in size. 



Both 3 i differ much from Moschler's figure of A. Quenselii^ var. 

 speciosa, in that the body is entirely black above, and the fore wings 

 have broader yellow bands and the hind wings are entirely black. 



Arctia ? 



A singular larva was found on the Larch, at Square Island, July 

 8th. It is remarkably short, thick, broad, and a little flattened ; and 

 so densely covered with short, evenly cut, very broadly spinulated hairs 

 that the segments of the body can not be distinguished ; the dorsal hairs 

 are shortest and thickest, those on the sides are longer and more un- 

 even. Seen from above, both ends of the body are concealed by 

 over-arching hairs, causing both extremities to look alike. The head 

 is black, body beneath black ; false legs livid ; hairs dark umber- 

 brown, appearing as if dusted over, owing to the remarkably long 

 pectinations or spinules of the hairs. On each side is a subdorsal,
