wings long but broader than in the preceding species ; costa 

 very faintly rounded ; apex full, almost angulated ; hind 

 margin curved, rather long and oblique, but very full at the 

 anal angle ; dorsal margin very slightly curved ; white ; 

 markings almost exactly as in the preceding species {C. fiir- 

 cula), except that the transverse purple-grey band is edged 

 outwardly by a regularly curved line, not indented ; the band 

 is also usually broader on the costal margin and less extended 

 on the dorsal. The basal dotted line, the first line, the triple 

 second line and following apical ovate blotch, the stigmatic 

 streak and the marginal dots are all as in C.furcula, as also 

 are the hind wings which, however, are a little longer and 

 have a more distinct central lunule. Female with antennse 

 more shortly pectinated, and body stouter, sometimes with 

 a conspicuous cloudy transverse grey shade on the hind wings, 

 otherwise quite similar. 



Underside of the fore wings clouded with pale smoky-grey, 

 with whitish bands ; margins white, with blotches and spots 

 as in C.furcula; central black stigma conspicuous; central 

 area of the wings thickly covered with upstanding whitish 

 scales ; hind wings white, with a long black central streak and 

 the usual marginal spots. 



Rather variable in depth of grey colour, but not so variable 

 in the distinctness of the black lines as C. furcula, nor so 

 much disposed to increased orange shading as that species. 

 In the late Mr. F. Bond's collection is a large female speci- 

 men in which the dark band of the fore wings is extremely 

 broad and much bent outward toward the anal angle. Mr. F. 

 Norgate has one in which the black lines are bordered on 

 both sides with pale orange, and another in which the dark 

 central band is extremely perpendicular and entirely blackish- 

 grey, the subapical oval spot being also very black and full. 

 This is an extremely handsome example. 



On the wing at the end of May, and in June.
