posterior veins thinly, upper ones lieavily black, this black scaling dilated at 



extreme edge of wing. Hindwing : a short, pale buff, triangular, discal band 



from costal margin to R^ or R-, often reduced to a patch before Sfl^ ; submarginal 

 black bars well defined, bar C— SU- generally excepted, upper ones arched, posterior 

 ones more straight, but curved distad at veins ; the bars form the outer border of 

 a large, pale blue, triangular patch, which is widest at M", reaching to base of 

 M', expanded between C or S(J- and SM-, narrowing costad, being only 2 to 

 3 mm. ))road between SC^ and R' ; admarginal interspaces maize yellow, forming- 

 a similar band as on forewing, very wide, upper patches widest, patch R' — ^R^ 

 measuring 6 to " mm. lietween veins, anal one greenish olive, veins within 

 band thinly black or bluish olive : black marginal line as in Ch. pelias 

 sattii-nns, extremely thin at anal angle, fringe heavily white, black only at tips 

 of veins. 



Underside as in Ck. pelias saturnus, slightly varying in the depth of the 



red and ochraceons tints. Forewing : median bars more distal, and discal 



ones, which are all present, more proximal than in sati/rniis, the white discal 

 interspaces reduced to a thin band, which, moreover, includes a series of ferruginous 

 red patches lietween SC^ and M^, hence the white band here represented only 

 by the distal white border of the median and the proximal border of the discal 

 bars ; postdiscal interstitial patches ochraceous rufous, touching each other or 

 fixintly separated, variable in size, mostly triangular, often transverse ; black 

 postdiscal patches as in saturnus, variable ; bluish olive grey scaling at this spot 

 less extended than in Ch. pelias, partly replaced by cream coloured scaling 

 posteriorly ; submarginal black bars not vestigial ; admarginal interspaces smaller 



than above and paler ; edge of wing black at ends of veins. Hindwing : as 



in saturnus, white discal band narrower, sometimes with ferruginous red scaling 

 at the outer side of the median bars C— R', besides the patch at costal margin, 

 median bar R' — M' sometimes vestigial ; ferruginous red postdiscal patches and 

 olivaceous submarginal interspaces narrower than in C//. pelias owing to the 

 extension of the admarginal interspaces ; upper submarginal black bars generally 

 rather shaded with olive grey ; blue snbmarginal spots conspicuous ; admarginal 

 interspaces a little smaller than above, very pale buff yellow, whitish at vein.s 

 distally ; dentition of wing as in saturnus, upper tail 5 to 8 mm., second 9 to 

 11 mm. long. 



?. Like (J, larger, upperside of wings a little more brown, white band of 

 underside broader, and postdiscal interstitial patches of forewing less bright. 



Length of forewing : cJ, 38 — 45 mm.

Genital armature as in Ck.jason.

Feisthamel, I.e., describes a sport in which the yellow colour of the band of 

 the hindwing above has changed into a greenish colour, and in which the underside 

 is greenish brown, with a broad middle band of a paler colour, tiie bars having 

 disappeared.
