witli two transverse rows of spots of the same colonv, the outer row consists 

 of seven very small markings with a white centre, the inner one of two sjiots 

 situated not far from the two first of the exterior row ; apical margin with 

 yellow double spots in the cellules, these spots form a narrow marginal band 

 which is interrupted at the nervules and is bordered exteriorly with a brownish 

 black line. 



Underside of both wings dark olive buft', tinged with yellow. Anterior 

 wings with three narrow black cellular streaks, the exterior of them flexuose ; 

 discocellular ner-siiles thinly bordered with black scales ; a thin short line near 

 the apex of the cell, two rather broad bar-like markings behind the cell, and a 

 transverse row of three angular marks between the median nervules and submedian 

 nervure, black ; a double mark in the anal angle, and a feeble spot in the next 

 cellule also black, bearing interiorly a yellowish olive, lunular marking each ; a 

 white spot near the costal margin corresijondiug to the spot on the upjier surface; 

 some faint submarginal lunules of a pale olive buff colour ; all the black markings 

 bordered with light blue. Posterior wings with a number of very thin black 

 lines : one basal, short ; the second between costal margin and median nervure, 

 crossing the basal half of the cell, interrupted at the nervures ; the third extending 

 from the costa to the median nervure again, crossing the apical half of the 

 cell, flexuose, scarcely interrupted at the nervures ; the others, short, standing in a 

 quite irregular transverse row, which begins in the middle of the costal margin 

 and ends at the inner margin rather close to the anal angle ; beyond the middle 

 of the disc there are some yellowish olive buff marks the posterior of which are 

 bordered inside and outside with black ; a submarginal row of very small spots, 

 light blue, each spot bearing a white point behind ; outer margin marked as on 

 the upperside, l)nt the yellow spots paler. 



Posterior wings shortly dentated, even more shortly so than in Gh. numenes 

 Hew. 



? . Upper and under surface of the forewings almost exactly marked as in 

 Cli. tiridates Cram., but the basal half of the upperside of a paler wood brown 

 colour. 



Upperside of the hindwings wood brown like the base of the forewings ; 

 apical and inner margins brownish black ; a small spot of grey scales beyond 

 the middle of the costa ; two or three ill-defined submarginal spots of a bafF 

 colour anteriorly at the inside of the blackish marginal area ; in this area is a 

 row of faint bluish grey spots ; outer margin with buff markings. 



Underside as in CIt. tiridates Cram. 



Tails of the hindwings very short.

The male diffei-s from Ch. tiridates Cram, and Ck. numenes How. in the 

 absence of the exterior row of blue spots from the forewings, in the inner row 

 on the hindwings consisting of two spots only, and in the pattern of the 

 under surface. Both sexes have the hindwings very shortly toothed.
