156 ZOOLOGICAL EESULTS OP THE EUWENZOEI EXPEDITION. 



Chakaxes opinatus, sp. n. (Plate V. fig. 7, 6 .) 



Expanse 78 mm. d" . 



Above the species has the appearance of a member of the C. ethalion group, and 

 below resembles some ally of C. anticlea^ thus apparently forming a link between these 

 two divergent groups. 



In wing-shape hardly differing from the same sex of G. ethalion, except that the 

 tornus of the fore-wings is a little less acute, while the hind-wings are rather more 

 produced and the tail at vein 4 is a third longer than that at 2, which latter is about 

 the usual ethalion length, though in that species the proportionate length of the tails is 

 reversed. 



Upperside. Head, body, and wings seal-brown, the wing-border narrowly black; 

 cilia white on hind wings and interrupted with black at veins on fore-wing. Fore- 

 wing uniform seal-brown. Hind-wing with a submarginal band about 1"5 mm. wide, 

 which is of an ochraceous rufous-brown colour, except at the tornus, where are a few 

 gallstone-yellow scales ; the submarginal spots, of the usual ethalion shape, are grey- 

 blue scaled with white centres, the white colour disappearing in the more costalward 

 spots. A narrow (1 mm.) post-discal macular band of tawny brown to dull brown 

 from vein 7 to 1 5, subparallel to the external margin. 



Underside. The markings in j'^ellowish and olivaceous greys suggest the brown to 

 light red ones of anticlea d , but on the fore-wing the discal band is proportionately 

 wider, more expanded costalwards, straighter externally, and more broken internally ; 

 the fine sinuate line which bounds externally the next patch of the ground-colour is, 

 from vein 1 to the costal margin, closer to the discal band, which thus exceeds the 

 width of the ground-colour band, except near the costa. On the hind-wings the space 

 outside this sinuate line is olivaceous green, with a faint line of demarcation from the 

 band of purple-grey ground-colour which adjoins it externally ; the outer border is 

 gallstone-yellow, becoming more rufous towards the costa. The dark linear mark 

 internally delimitating the lunules of purple and grey scales, and the marginal line 

 of hind wings, black. 



The underside of the palpi and breast, and the tarsi of the fore legs, pale Naples 

 yellow. Underside of the thorax and abdomen, and the tibiae and tarsi of the raid and 

 hind legs, of the same grey shade as the underside of the wings.
