346 APPENDIX. 



the males, which are generally so unlike the females that their sexual 

 relations might readily be questioned. 



In the male specimens of C. lone, captured by Mr. Oates at Tati, 

 the fore wings have the faintest trace of a very minute black discoidal 

 dot, a brilliant silky purple subapical patch, the apex itself black, and 

 the inner edge margined with black, which is slightly scalloped. The 

 hind wings are pure white, with delicate black veins, without any 

 discoidal spot. On the under side the fore wings have the minute 

 discoidal dot, and the apical patch is replaced by pale greyish buff, 

 with a slightly defined darker inner margin ; the veins of the hind 

 wings are not black, the basal half of the costa is orange, with a short 

 brownish transverse dash, near the middle of the costa, extending only 

 to the first branch of the subcostal vein ; the remainder of the wing 

 white. One of Mr. Oates's specimens is very small (if inch in the 

 expanse of the fore wings), with the black veins excessively slender.

The males have the veins of the fore wings, beyond the middle, 

 very slender and black, and with a very minute discoidal dot. The 

 female of this species, represented for the first time in the former 

 edition of this work, as cited above, has the wings on the upper 

 side white, with the veins concolorous ; a large black round spot at 

 the extremity of the discoidal cell, and a large purple-red subapical 

 spot, down the middle of which is a richer shade of purple, edged 

 internally with blackish brown, the apex and apical margin being of 

 the latter colour ; the base of the wings is slightly powdered with 

 greyish scales, and there are two minute dusky dots towards the inner 

 angle of the fore wings. On the under side the purple patch of the 

 fore wings is replaced by dirty pale buff, having an oblique row of five 

 pale black spots, and the hind wings are slightly fleshy buff coloured, 

 finely freckled all over with pale brown irrorations, with a discoidal 

 spot, and a curved row of oblong spots beyond the middle of the wing, 

 of pale brown ; the costal margin is slightly fulvous at its base. The 

 expansion of the fore wings is 2fV inches. Taken at Tati. 



A male, in the Hopeian collection, from the Zambesi, has the hind 

 wings marked along the outer margin with black dots at the extremity 

 of the longitudinal veins.
