ENTOMOLOGY. 339 
of the fore wings marked with a brilliant blue or pale purple patch, 
are so closely allied together as to suggest the possibility of their being 
geographical sub-species ; they appear indeed to be constant in their 
characteristic markings, and the females are even more distinct than 
the males, which they are generally so unlike that their sexual rela- 
tions might readily be suspected. 
In the male specimens of C. lone., captured by Mr. Gates 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 
wirigs 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 the specimens taken by Mr. Oates at Tati is very 
small (i| 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, here for the first time represented (PI. E, figs. 
9, 10), has the wings on the upper side white, with the veins concolor- 
ous ; 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 grayish 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 2/^ 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.
