450 FROCEEDINUIS OF THE NATIONAL MUt^EUM. 



CENEIS SEMIDEA(?) (Say). 



Five specimens from the Barren Grounds and one from Point 

 Epworth, taken by Hanbiiry, are referred by Mr. Elwes to either 

 seinldea^ or eramhls Freyer, Init not closely approaching either.* 

 Oranihis is given as a synonym of xnhJiyalina by Dj'ar.^ 



CENEIS CARYI Dyar. 



The tjT^a of this new variety, a male in beautiful condition, was 

 taken June 13, 19(»3, in an open growth of Banksian pine {Pluas diva- 

 rlcatd) on the Smith Portage, Atliabaska. 



Caryi is a form of norna-y and differs from that species, as well as 

 from var. h(f(ihdhi Newcomb, in having the red color of the wings 

 much darker and more rusty. 



CENEIS NAHANNI Dyar. 



The type of this well characterized species came from Nahanni Moun- 

 tains, Mackenzie. The pair from which it has been described was 

 collected on Mount Tha-on'-tha, Nahanni Mountains, Mackenzie, July 

 16, 1903, at 2,500 feet altitude. 



Butterflies of this genus were fairly common on the north slope of 

 the mountain, occurring chietl}^ among the rock slides. It v/ould be 

 impossible to say which species predominated, as I was occupied with 

 miscellaneous collecting, and merely caught lepidoptera as occasion 

 offered. There is no distinguishing of species on the wing with but- 

 terflies of this genus. One habit all shared alike — that of ''sneaking," 

 i. e., crawling and half flitting about on the rock piles until a conven- 

 ient crack or crevice afforded them concealinent. This Avas almost 

 invarial)ly done inuiiediately after the insect alighted. I found them 

 very diflicult to flush, and when a butterfly did take to the air the 

 flight seldom was sustained for more than a rod. 



O. nahanni differs in color from aider I Reakirt, and the markings 

 and striations below are much coarser than in the forms of noma 

 Thunberg. I can do no better than quote the characterization from 

 the original description:^ 



Blackish above, washed with ferruginous brown, the veins darker, tlie markings of 

 underside showing. A small ocellus or none above vein five, on fore wings, two to 

 five on hind wings, the one above vein five largest, the rest small or absent. Hind 

 wings below black and white, coarsely strigose, somewhat as in uhleri Reakirt, and 

 varuna Edwards, but much more densely, the white of the wing being largely 

 obscured. Median band weakly indicated; ocelli black with white pupils; fore 

 wings shaded with red over the disk.
