DESCRIPTION OF A NEW SPECIES OF CHIONOBAS FROM 



BRITISH AMERICA. 



BY W. H. EDWARDS, COALBURGH, W. VA. 



CHIONOBAS MACOUNII. 



MALE. — Expands 2.2 to 2.4 inches. 



Upper side brown-orange, color of C. Californica Boisd.; occasional 

 examples are dark, a dead-leaf-brown over whole surface ; hind margins 

 edged by a blackish border, of nearly equal width throughout, and ex- 

 tending to apex of primaries ; but sometimes this border is widest on 

 primaries ; costa of primaries dark brown ; in some examples this shade 

 scarcely if at all crosses costal nervure, in others it encroaches on the cell 

 more or less, and occasionally covers the whole cell ; but in nearly all 

 examples under view the cell is concolored with rest of wing ; the obHque 

 discal brown band, which is a conspicuous feature in the males of the 

 alhed species, does not appear in the present one, so far as the examples 

 show ; the coloration of the upper surface resembles that of the female of 

 Californica ; on secondaries, the costal margin is edged with brown, and 

 just outside the end of cell is an expansion of this, which forms a large 

 elongated patch, convex on interior side — not at all like the sub-triangular 

 and small patch seen in Californica and Idiina ; primaries have a black 

 ocellus, rounded or oval, with white pupil on upper discoidal interspace, 

 and a second on second median interspace, the last one usually blind, but 

 sometimes pupillated ; generally the lower ocellus is smallest, but occasion- 

 ally is equal to the upper ; one example under view has two additional 

 black spots, as large as the ocellus on secondaries, one on the interspace 

 next above each ocellus ; another has mere points on these interspaces ; 

 secondaries have a small ocellus, either blind or with white pupil, in 

 second median interspace ; fringes of both wings alternately yellow-white 

 and brown-black. 



Under side of primaries paler, frequently yellowish ; costal edge gray- 

 white, specked and streaked transversely with dark brown, next before 

 and at apex gray prevailing ; the hind margin brown ; the cell more or 

 less specked with brown, and just beyond the middle from base crossed 

 by a narrow brown stripe. 



Secondaries usually gray-white over costal margin and to middle of 

 cell, yellowish over remainder of wing, but sometimes the entire surface is
