ciated with a closely allied form, P. Mohopaani, Wallengren, 
which may be easily distinguished by two viteous spots in the dis- 
coidal cell of the fore-wing, and (in the ¢ ) by the discal streak. 
23. Pamphila Marchalii, Boisd. 
I did not meet with this insect, but observed a much injured 
Pamphila in Mr. Caldwell’s collection which I referred to the 
species. Since my return to the Cape, Lady Barkly has sent me 
a g example, which was, I believe, taken in the grounds at 
Réduit. The species is easily distinguished from P. Borbonica 
by its rufous-brown colour, orange-mixed cilia and under surface, 
and by the absence of spots, there being only two small discal 
vitreous ones in the fore-wing (between the first and third median 
nervules), and none in the hind-wing. The outline of the wings 
also differs, being considerably less prominent in the apical region 
of the fore-wing and in the anal-angular region of the hind-wing. 
24, Nisoniades Sabadius, Boisd. 
I met with this species only in wooded ground at Réduit, where 
I noticed six or seven examples and took three. It is rapid and 
active in its movements, frequently settling on the under surface 
of leaves. It frequented the small blue flowers of a species of 
Salvia abundant on the estate. ‘The wings are held fully expanded 
when the butterfly is at rest. Mauritian specimens are smaller, 
redder in tint, and less distinctly marked than the South African 
examples of the species. 
25. Ismene Florestan, Cram. 
Not a common butterfly in Mauritius: I saw but four specimens 
on the wing during my stay. Its flight is very swift, but is some- 
what bustling, reminding one of that of the diurnal Noctuina, e. g. 
the Plusig. Like the moths referred to, Florestan seems to 
require much nourishment, and keeps steadily to flowers, from 
which its long proboscis pumps the nectar in a most effectual and 
business-like manner. The wings are elevated when the insect is 
settled, the hinder pair being held slightly apart from the fore- 
wings. I found this species at Port Louis, Pamplemousses and 
Vakoa; and Lady Barkly has sent me examples taken at Réduit. 
All these individuals belong to the type-form of the species; the
