the Butterflies of Mauritius. 303 
9. Atella Phalanta, Dru. 
This butterfly is by no means uncommon in Mauritius, but it 
is smaller and with stronger markings than those occurring on the 
African continent. The largest specimens that I have seen are 
from China. I found Phalanta most numerous at Pamplemousses, 
but took it also at Terre Rouge and at Vakoa. It is stated by 
M. Maillard to be “very common” in Bourbon, the @ being, 
however, much rarer than the ¢. 
10.4 Pyrameis Cardui, Linn. 
I was surprised not to meet with this familiar acquaintance in 
Mauritius, seeing that Boisduval mentions it as one of the insular 
inhabitants. A Mauritian example, given me by Mr. Caldwell, 
differs in no respect from the usual appearance of the species. 
M. Maillard records the butterfly as a native of Bourbon. 
11.¢ Pyrameis Hippomene, Boisd. 
This handsome insect appears to be decidedly scarce in Mauri- 
tius, and, according to M. Maillard, is rare in Bourbon. Mr. 
Colville Barclay showed me the wings of a specimen taken by him, 
some years ago, in the Moka district. From these, from some 
specimens which I hastily examined in the Port Louis Museum, 
and from Boisduval’s figures and description, I think that the 
Mauritian form of the species may well be held distinct from the 
south African form as a marked variety, if not as a sub-species. 
The examples from Mauritius are considerably larger and darker, 
with the apical region of the fore-wings and the tails of the hind- 
wings much more produced ; the apical white spots of the fore- 
wing are smaller, and the under-surface markings of the hind-wing 
are brighter, with the strize more angulated. 
12.* Junonia Rhadama, Boisd. 
I was rejoiced to find this brilliant butterfly not uncommon in 
Mauritius. I first saw it flitting about a grassy bank at the side 
of the road at Terre Rouge, between Port Louis and Pample- 
mousses, and instantly recognised the species by its size and 
colour. The richness and glitter of the metallic-blue upper- 
surface in a fresh ¢ is exquisitely beautiful, as the insect basks 
with fully expanded wings in the tropical sunlight; and the @, 
though less splendid, is by no means inconspicuous. In flight the
