Uiidermle pale drab or fawn-colour, sometimes ecru drab ; basal to median bars 



light chestnut. Forewing : basal cell-spot conspicuous, three cell-bars heavy : 



median bars li^— SM- in a nearly straight row, almost at right angles to veins, bars 

 R'—M-' curved distad, ends pointing basad, bar R^— R^ about ^ to 2 mm. from cell, 

 2| mm. from bar R" — R- ; discal interspaces ecm drab at median bars, this colour 

 forming an inconspicuous baud of about 3 mm. width, rest of discal interspaces 

 bistre colour ; postdiscal bars strongly arched, black, the series turning basad from 

 R' to SC* ; j)ostdiscal bars represented by patches, of which the submedian ones are 

 black and nearly fused together, while the others are chestnut, patches SO'— R^ and 

 R^ — M' small ; these patches followed posteriorly by creamy ones, of which only 

 patches M' — SM^ are clearly marked, wliile the others become somewhat con- 

 spicuous only in consequence of the snbmarginal luniform bars, which border 

 them distally, being rather obviously marked in this species ; tips of veins chestnut; 



margin with creamy spots between veins. Hindwihg : median series of bars 



nearly continuous, curving distad in middle, crossing M' 2i mm. from base of vein ; 

 basal costal bar and basal cell-spot present, subbasal costal bar also marked, cell-bar 

 3 sometimes indicated by a dot ; submediau bars M — SM- forming together an 

 acute angle which points distad, a pale chestnut line along part of fold SM- — SM^ 

 another, shorter, one behind SM^ ; discal, strongly arched, bars blackish chestnut, 

 close to median series, the distance being nearly the same from C to M", about 

 1 to 2 mm. between veins ; postdiscal bars halfmoon-shaped, chestnut, the second, 

 fourth and fifth vestigial, all separated from discal bars by pale halfmoons, of which 

 the last three are cream-colour or yellowish cream-colour ; the postdiscal spots 

 outwardly shading into drab, this colour much extended between C and R' ; sub- 

 marginal black dots shaded proximally with bluish grey scaling, and the upper 

 three, besides, with drab scales, which form a halfmoon the ends of which point 

 distad, the wide interspace between the series of submarginal and postdiscal 

 spots pale cream-colour; admarginal interspaces bnff; admarginal line as above, 

 anteriorly broader ; veins brown within i)ale area ; upper tail slightly widened 

 beyond middle, 8 to 9 mm. long, second thinner, faintly curved costad, to 

 mm. long. 



?. Like cj, larger, wings broader, creamy colour slightly more extended; 

 upper tail 9 mm., second 7 mm. long. 

 Length of forewing : S 39 — 44 mm. 



„ ,, ? 47 mm. 



Clasper broad, produced into a rather short, evenly curved, slender, but strongly 

 chitinised hook ; 10th tergite broadly sinuate, the two processes conical, rather 

 thin ; penis with one large tooth standing before the apex and a few minute ones 

 further back (PI. H. f. 6.) ; penis-funnel as in Ch. marmax. 

 Hab. Timor and Wetter. 



The most interesting feature of this peculiar species is the development of what 

 is in other species a series of white submarginal dots on the hindwing to a very 

 broad band, necessarily accompanied by a basad movement of the postdiscal bars, 

 which in the other species of this grouji are fused with the snbmarginal bars. The 

 submarginal band on the upperside of the forewing corresponds to the white 

 submarginal scaling of the underside found in all the tawny Ckaraxes. Dr. Butler, 

 in his Revision of the genus Churaxes put orilus between fabius and etkeocles 

 from which it is very dilfereut both in structure and pattern. It is like ocellatus a 

 member of the polyxena group.
