544 Di. i Eltringham on the 
and three, sometimes four beyond it. A submarginal border con- 
sisting of two lines faintly darker than ground-colour, between 
which are developed minute white dots especially towards the apex. 
A small hind-marginal spot of deep yellow followed by a large discal 
spot in 2 and 3, more quadrate than in /robenia. A subapical spot 
made up of patches of nearly equal length in 5, 6, and 8. H.-w. 
with traces of a hind-marginal border of lighter and darker markings 
and with a discal band of deep yellow of sharply defined but irregular 
outline, not more than about 3 mm. wide at its broadest part, deeply 
concave between the nervules from 1b to 4 and projecting suddenly 
outwards in area 4, 
Underside more or less reproducing the pattern of upperside, but 
ground-colour much paler and f.-w. hind-marginal and subapical 
spots nearly white, also a whitish transverse mark across end of 
cell. Hind-wing base with faint indications of pale spots, a curved 
row of small whitish spots in 4, 5, 6, and 7, followed by the discal 
band which is white or pinkish, sharply defined on both edges, and 
distally edged with dark brown followed by a greyish line. Slight 
indications of a double submarginal row of pale spots. Male with 
a pearly opalescent area in f.-w. extending from inner margin 
beyond nervule 2. 
The following description of the larva is from Oberthiir. 
Originally fed on Trajia reticulata, but now feeds on Acalypha 
marginata, plants introduced from Mauritius. Larva pale chestnut. 
Flexed, about 22 mm. long. Six lateral membranous protuberances ; 
the intermediate ones longer and projecting forward like horns. 
Three sublateral festoons edged with white and above the angle 
of the festoon white oblique marks. The last festoon rises posteriorly 
towards the caudal extremity, which ends in four fine points. Under- 
side rose brown. The last segment has a pale shining mark of 
“ arabesque’ form. A paler median dorsal line arises from the 
prothorax and ends well before the caudal extremity. 
The chrysalis is angular, short, flattened laterally, and projecting 
at the alar extremities. Gold pink tending to yellow or cream, 
opalescent. All the dorsal projections end in green points with 
a green iridescence. The prominent abdominal lines are touched 
with gold. The abdominal segments have a gold reflection. 
Alleged occurrences of this species elsewhere than in the 
island of Bourbon seem unreliable. The male clasper 
resembles that of comorarum, but presents small differences 
which will be noted in the figure.
