nervure ; the disco-cellular nervules defined with a fine black line ; beyond 

 which is a bow-shaped figure composed of two lines joined at their ends, 

 the outer line straight, the inner one curved, with their points resting on 

 the second median nervule and subcostal nervure ; below the cell a pair of 

 streaks reaching the inner margin, the origin of the inner one being where 

 the first median, and the outer one where the second median nervule is 

 given off, the space between them being thickly irrorated with black scales, 

 leaving but little of the ochreous ground-colour visible ; two discal lines from 

 the subcostal nervure to the inner margin, the outer one lunulate, the inner 

 one sinuate, the two lines being nearer together at their middle, wider apart 

 at the inner margin, the space between them and within the inner one 

 being irrorated with black scales ; a submarginal series of seven bright 

 ochreous spots, broadly defined inwardly with black, one in each interspace 

 except the two lower, which are smaller and placed between the first median 

 nervule and the submedian nervure ; the outer margin broadly black, bear- 

 ing two obsolete paler lines. Sindwing crossed by four black lines, the 

 space between each pair, and between both pairs being thickly irrorated 

 with black scales, especially at the lower extremity of the outer pair, where 

 the ground-colour is entirely black, at the upper extremity the ground- 

 colour increasingly to the costa is very pale ochreous ; a submarginal line 

 composed of six lunules, each lunule having a bright ochreous spot placed 

 outwardly against it ; the outer margin more broadly black than in the 

 forewing, the black portion ending at the first median nervule, bearing two 

 intensely black lines, the outer one defined on both sides with a pale fine 

 line, the outer of these two pale fine lines becoming almost pure white 

 from the tail to the anal lobe ; which latter, together with a round spot 

 above it is bright ochreous, defined (especially outwardly) with black. 

 There are also some small white, black, and metallic deep steel-blue mark- 

 ings above the round ochreous spot. The tail black, the extremity white. 

 Undeeside pale ochreous, the outer portion of the forewing and on either 

 side of the submarginal lunules on the hindwing somewhat deeper ochreous, 

 becoming ferruginous at the anal angle of the latter. All the markings 

 of the upperside, but narrower and better defined, with no black irrorations, 

 the outer margins (except the extreme margin which is black) concolourous 

 with the rest of the wings ; the veins throughout pale ochreous. AnttnncB 

 black, the extreme tip ochreous. Thorax and hodg rich ochreous above 

 marked with three black lines, beneath pale ochreous. 



Length of forewing 1'15 ; whence expanse = 2"4i inches. 

 Hab. Great Nicobar. 



Closely allied to C. tJiyonneus^ Cramer (pi. ccxx, figs. E, F), from 

 Amboyna and Bouru in the Malay archepelago, but differing from the
