Butterflies of Mauritius and Bourbon. 439 
None of the larve I have seen agree with Dr. Vinson’s 
figure and description of the larva of A. borbonica (Oberth. 
“Etud d’Ent.” 12, p. 17, t. 4, 1888), except that the spines 
are yellow with black points, set on bright yellow or dull 
ochreous bases. The pupe are similar in shape, but, as I 
have shown elsewhere,* the colour is markedly influenced 
by its environment. 
The larva is very easily detected by its habit of forming 
a tent for itself by making two scimitar-shaped incisions 
in a leaf right down to the mid-rib, and then bending over 
the tip and attaching it to the under surface of the leaf 
with a few silken threads. The full-fed larvee frequently 
discard this method of concealment and feed openly, but 
invariably rest on the under surface of the leaf. 1 have 
found eggs, larve and pupz on the same plant at the 
same time. 
Antanartia borbonica, Oberth. 
Common in Bourbon above 2,000 feet, abundant at 
Hell-bourg, Salazie, 3,000 feet. I never saw the perfect 
insect, but evidences of the larva were everywhere abun- 
dant on the food-plants. My only captures were one 
empty egg-shell and one cast larval skin, which was 
aggravating, but illness was responsible for my non-success. 
It was considered to be peculiar to Bourbon, but Mabille 
has lately recorded it from the interior of Madagascar. 
Pyrameis cardui, L. 
10. Pyrameis Cardui, Linn. 
Mauritius. Rare and local. Its chief and almost only 
locality is the Trou-aux-cerfs, 2,000 ft. where I have 
occasionally found it in December, though it occurs 
sparingly in other months. It differs in no way from 
European specimens. 
Bourznon. Rare, and only in the hill districts. I saw 
a beautifully fresh specimen at Hell-Bourg, 3,000 ft. in 
April, 
Precis rhadama, Boisd. 
12. Junonia Rhadama, Boisd. 
Mauritius. Common everywhere and_ frequently 
abundant on the coast. It is perhaps the most strikingly
