Butterflies of Mauritius and Bourbon. 4.49 
indeed I have not personally met with the latter, but am 
under the impression that I have seen one or two 
specimens in the Port Louis Museum. Its absence can 
be readily understood in the damp climate of Mauritius. 
It is not common, but is found at Moka and in the 
Botanical Gardens at Pamplemousses almost at sea-level, 
always in the neighbourhood of its food plant Tephrosia. 
It is absent, or very rare (once at Curepipe) above 1,000 
feet, and disappears in the cold weather. It is very 
variable in size, those found in October being usually 
larger than those captured in April. The transformations 
of 7. brigitta are well known, but those of 7’. pulchella 
have not been described. 
The egg laid April 9th; hatched April 11th. Spun up April 19th, 
and the butterfly emerged May 2nd. The larva when first hatched 
is uniform pale yellowish-green, and when magnified is seen to be 
covered with whitish reversed hairs, which, however, disappear 
when the larva is full grown. The full-fed larva is green, with thin 
yellow spiracular, and broader purplish-brown dorsal, lines. Pupa 
pale apple-green, wing covers streaked with purplish-brown; dorsum 
and sides thickly sprinkled with small spots of the same colour. 
Spins up on the stem of the food plant. Larva and pupa of the 
usual Pierine shape. 
It does not occur in Bourbon.

This beautiful buttery is common everywhere and 
excites the admiration of the least observant. It flies 
all the year round, though the specimens seen in the cold 
weather are usually tattered individuals of longer life than 
their fellows. The female can easily be distinguished on 
the wing by the absence of the white band which is such 
a conspicuous feature on the undersurface of the hind 
wing of the male. The larva feeds on citron, but I am 
unable to say in what respect it differs from the Bourbon 
species P. phorbanta. Dr. Vinson, writing on the butter- 
flies of Bourbon in 1896, makes the following interesting 
remark. He says that in 1669 the Count of Mont de 
Vergne arrived with ten vessels and sowed Madagascar 
and afterwards “Mascareigne” and Mauritius with the 
seeds of various citrons which he had brought from
