CHIONOBAS I. 
CHIONOBAS IDUNA, 1-4. 
NEW SPECIES. 
Primaries in male much produced, costal margin nearly straight ; hind margin 
of primaries in both sexes slightly rounded, of secondaries deeply sinuate ; the 
exterior outline of discal band on under side of secondaries not scolloped, irregu¬ 
lar. 
Male. — Expands 2.5 inches. 
Upper side brown-orange, bright on primaries, less intense on secondaries; 
hind margins edged by a narrow fuscous border, of nearly uniform width on 
secondaries, but narrow on primaries at inner angle, and much expanded at 
apex, the inner side entire; costal border of primaries dark brown; upon the 
disk, from the lower outer angle of cell to sub-median nervure, and encroaching 
somewhat on the cell next above median, an oblique, dark brown band, the ex¬ 
terior side convex, the interior somewhat undefined, nearly lost in the brown 
shade that covers the basal half of cell; on the upper discoidal interspace a large, 
oval, black ocellus, without iris, with small white pupil ; sometimes in the next 
interspace above is a minute, round, black ocellus, either with or without white 
pupil, and a similar one, but blind, in the second median interspace; this last 
ocellus however, may be large and pupillated, and accompanied by a small 
blind ocellus in the first median interspace ; the number of ocelli therefore 
varies from one to four, and when four are present, two are large and pupillated; 
and whatever the number, they are so placed that a straight line would pass 
through the centre of each one ; secondaries have the costal margin slightly 
flecked with brown; at outer angle sometimes a small, brown, sub-triangular 
spot, but often wanting; on the second median interspace a small ocellus, either 
with or without white pupil; often this ocellus is wanting ; fringes of primaries 
fuscous cut with sordid white at middle of each interspace; of secondaries fus¬ 
cous, largely pure white in the interspaces. 
Under side of primaries paler; a dusky shade over cell corresponding to the 
oblique band; costal edge gray-brown, irrorated with blackish-brown next base, 
with white beyond ; at apex gray and white equally mingled ; the hind margin
