330 Mr. R. Trimen’s Votes on 
noticed that specimens were continually visiting trees of the Citrus 
group, upon which Boisduval notes that the larve feed. I never 
saw a living specimen of the $, and from what Mr. Caldwell, 
who kindly gave me an example, stated as his experience, I be- 
lieve it to be very scarce. In connection with the apparent rarity 
of this sex, it is interesting to observe that M. Maillard * notes 
the 9 of the very closely-allied Papilio disparilis of Bourbon 
is much rarer than the ¢, the proportion of g to ¢@ being 
20 tol. Mr. Bates (Proc. Zool. Soc., November, 1863), with 
some doubt, includes a single specimen of P. Phorbanta in a col- 
lection of Mr. Caldwell’s as a native of Madagascar. Judging 
from what is known concerning the nearly-related forms in other 
Archipelagic groups, it seems to me highly improbable that Phor- 
banta co-exists with its very close ally Epiphorbas, in Madagascar. 
In looking over Mr. Caldwell’s collection at Port Louis, I found 
that his Madagascarene and Mauritian captures were mingled 
together, and it is not improbable that in the collection submitted 
to Mr. Bates for examination, an example of Phorbanta may have . 
been inadvertently substituted for Epiphorbas. 
2.* Callidryas Florella, Fabr. 
This did not appear to be a common insect in Mauritius; but I 
met with several specimens in Port Louis, at Réduit, and at Pam- 
plemousses. It is a species widely distributed over Africa, and is 
found in the Cape de Verde Islands; but I am not aware of its 
occurrence in Madagascar, though, as Dr. Peters met with it at 
Querimba, and M. Maillard found it ‘very common” in Bourbon, 
there is good ground for imagining that it does inhabit the great 
island. 
A specimen of Florella was among a few other butterflies 
shown to me as having been collected by Dr. Burrowes, of 
H.M.S. “ Ariel,” at Zanzibar. 
3.* Callidryas Rhadia, Boisd. 
A species rather scarcer than C. Fiorella, but of quite similar 
flight and habits. Taken at Réduit and at Pamplemousses, and 
seen at Riversdale. This Callidryas has also an extensive African 
range, though I find no record of its inhabiting Eastern Africa.

knowledge of which I owe to the kindness of Mr. Edward Newton, of 
Mauritius.
