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 inten)5e on secondaries ; 

 hind nuirgins edged by a narrow fuscous border, of nearly uniform width on 

 secondaries, but n.arrow 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 secondai'ies 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
