insect is a thorough Vanessa, often settling, but active, wary and 
rapid. Boisduval’s figure (Faune Ent. de Mad. &c., pl. vii. fig. 
2) gives but a faint idea of the size and beauty of Rhadama.. ‘The 
outline of the wings varies much, but the angulation is more 
marked in the 2 than inthe ¢. In both sexes there is a double 
streak of a lighter blue than the ground-colour along the hind- 
margin of the hind-wing; and, in the same wing, between the 
lower sub-costal and discoidal nervules, a second ocellus, dull- 
red, black-ringed (with a black-dotted violaceous pupil), which is 
occasionally almost obsolete in the ¢, but always large and well- 
marked in the @. In the latter sex, the small ocellus in the 
fore-wing is more distinct ; the apical white dots in the same wing 
are larger, while there is a row of four other white spots from the 
costa, conspicuously margining the outer edge of the transverse 
black streak ; and the blue is duller, and much obscured in the 
basal regions of both wings. Some ¢ specimens present a fuscous 
surface, in which the blue is almost obsolete. As in most species 
of Junonia, the under-surface is very variable in both sexes, 
chiefly in the number and distinctness of the ocelli: in some 
examples it is throughout suffused with greyish, while in others 
the whitish and blackish streaks and shadings are conspicuous. 
I found this species at Réduit, in the Pamplemousses Gardens 
(where it frequented the attractive flowers of Lantana), and once 
in Port Louis. It was very interesting to learn, on the testimony 
of many residents (including M. Bouton, Superintendent of the 
Museum, Mr. Caldwell and Mr. Colville Barclay), that the but- 
terfly was unknown in Mauritius till a few yearsago. It appeared 
suddenly in 1857 or 1858, and was not rare from the first, several 
specimens having been brought to the Museum at that time from 
different parts of the Island. M. Maillard observes, that it is a 
“‘yvery common” insect in Bourbon, and Dr. Peters found it at 
Querimba on the Mozambique Coast; so that Rhadama, until 
lately supposed to be a peculiar product of Madagascar, appears 
to be not only extending its range, but to have been probably 
African in its origin. 
13.¢ Junonia Augustina, Boisd. 
This fine and very peculiar looking Junonia is only known to 
occur in Madagascar, Bourbon and Mauritius. In the latter 
island it is rare, and, according to M. Maillard, is seldom to be 
met with in Bourbon. I saw some faded examples in the Port 
Louis Museum, and two or three, much damaged by insects, in a
