" Upperside, black. Anterior wings with ca row of six bhie spots, forming a 

 band from near the apex to near the middle of the inner margin, the first spot 

 small, the others gradually larger, the spot on the inner margin being the 

 largest ; a blue spot within the cell near the discoccllular nervules. Posterior 

 wing with a similar band of spots from the centre of the anterior margin across 

 the middle of the wing to the fold ; a submarginal row of eight minute bluish- 

 white spots, and a marginal thin blue line extending from the inner margin 

 beyond the tail, which is small. 



" Underside resembles C. Kcsiope and C. Mtjccrina* This species differs from 

 Xf'aiopc in the position of the blue spots on the upperside of both wings, and the 

 row of small white spots on the posterior wing, and from Mycerina in the absence 

 of the broad blue band within the cell of anterior wing, as well as in the position 

 of the band of blue spots on both wings, and on the posterior wing in the sub- 

 stitution of the row of small white spots and the thin blue marginal line for the 

 band of blue spots on the margin of Myctrina.

The specimen fi^^-ed is a male. The under surface is more uniform in colour, with more 

 sharpl}--defiued markings than in C. Nesiope. The fore wings are of a light reddish-brown, 

 darkest on the hind margin below the apex, beyond the brown hne (only distinct below), which 

 runs to the inner margin at two-thirds of its length ; in the cell, near the base, are two round 

 black dots, in whitish rings, the upper one furthest from the base ; there is a black streak on the 

 upper part of the discocellular nervules, and two black irregular undulating lines, inteniipted by 

 the nerrures, cross the wings, one within the cell, and one beyond it, each narrowly edged with 

 whitish ; the palest part of the wing is between the outermost line, and the obsolete brown hne 

 running from below the tip. The hind wings are of a more silver}' and paler grey than the fore 

 wings, with two undulating inteiTupted Unes similar to those on the fore wings, the innermost 

 nearer the base, the outermost running (more faintly below) as far as the lowest median nervule ; 

 from a point corresponding to the obsolete brown line on the inner margin of the fore wings a 

 slightly curved dull-reddish line nins nearly to the anal angle ; nearer the hind margin is a row of 

 eight white dots, as above, the two nearest the anal angle being nearest together and marked with 

 black ; along the hind margin runs a red line, commencing opposite the second spot from the 

 costa, and ceasing nearly opposite, or a little before the seventh spot.
