In its general character this species closely resembles C. orithea. The specimen in 

 the Hopeian Collection is a male, having the fore wings triangular and pointed at the 

 tip, and the oval patch of rough black scales on the upperside of the base of the hind 

 wing, and the tuft of luteous hairs on the hind margin of the underside of the fore 

 wing, whilst two individuals in the British Museum, from Espirito Santo, want these 

 characteristic sexual markings. In these two specimens, however, the antennae are 

 slightly bipectinated, proving the anomalous fact that simple antennse may be 

 characteristic of the males of a species of which the female has those organs more or 

 less pectinated. 



In the Hopeian specimen the coloured patch of the hind wings is elongate-conic, 

 broadest at the costa, with its sides nearly even and straight, and terminating in a 

 somewhat flesh-coloured streak extending nearly to the anal angle ; but in the British- 

 Museum specimens the outer margin of this blue patch is somewhat more scalloped. 

 The terminal joint of the palpi is very short and clavate. On the underside the wings 

 are brown, the basal portion being only slightly tinted with ochreous buff; the fore 

 wings without the pale marks at the base, the central one entii'e and white with a 

 pearly tinge, the apical margin nearly as on the upper side. The under wings beneath 

 have a slightly defined, central, oblique, waved fascia of palish lilac, preceded towards 

 the base by two slender, brown, dentated, waved lines. The patch of luteous hairs on 

 the underside of the fore wings is covered by the costal margin of the hind wing, and 

 forms a triangular patch lying flat on the wing, and reaching to the first branch of the 

 median vein. Beyond the fascia the hind wing is uniform brown with a small 

 pale triangular patch between the anal angle and the tail, which is brown and tipped 

 with white.

The remarkable elongated and bipectinated antennae of the female in this species 

 distinguish it at once from all its congeners. As the wings do not exhibit the secondary 

 sexual characters noticed in the males of the preceding species, I am compelled to
