559. Hiposcritia cardena, Hewitson. 
Grose Smith. Snellen. Wallace. Distant. Hagen. Quite as 
common as H. pandione, Hiibner, and occurs in the same localities 
throughout the year. No female obtained.

560. Saletara nathalia, Felder. 
Grose Smith. Snellen as panda. Hagen. Wallace. Distant as 
nathalia and panda. Mr. Distant records both S. panda , Godart, and 
S. nathalia from the Malay Peninsula and Sumatra. Dr. Wallace con¬ 
siders that S. panda is confined to Java, while S. nathalia also occurs in 
Java, and in the Malay Peninsula, Sumatra, Borneo, the Philippine 
Isles, and Celebes. S. panda in the male is known by the pale primrose- 
yellow colour of the upperside, while S. nathalia is “ creamy white with 
a faint greenish tinge.” I greatly doubt if this character is sufficiently 
constant to separate the two species, I have one specimen from Sumatra 
which is quite intermediate between them. Mr. Distant considers that 
S. nathalia having five [three according to my way of computing 
them] subcostal nervules to the forewing in the male, while S. panda 
has only four [two], while the females of both species has four [two], 
is a character by which the two species may be separated, though 
he admits that he has a specimen of S. nathalia in which one wing 
has the neuration of S. nathalia , while the other has that of S. panda. 
In my series of thirty males of this genus, I have one from the Philip¬ 
pines and one from Singapore with two subcostal nervules only, one 
from Singapore, one from Great Nicobar, and one from Little Nicobar 
with two subcostal nervules on one side only and three on the other, 
while all the rest have three subcostal nervules on both sides. The 
females seem to be more constant, having two subcostal nervules only in 
all the specimens I have been able to examine. Neuration certainly 
will not suffice to keep these two species distinct. I use Felder’s name 
for the species as most of the writers on Sumatran butterflies have done 
so, and as the majority of male specimens from thence agree with the 
description of that species rather than with that of S. panda , the older 
name. It has been beautifully figured by Heer P. 0. T. Snellen as Pieris 
panda , Godart, in Midden-Sumatra, Lepidoptera, pi. ii, figs. 9, 10, 
male; 6, 7, female (1892). It is found only in the forest at low ele¬ 
vations, not higher than Namoe Oekor as far as we have noticed, but 
Dr. Hagen mentions its occurrence on the Central Plateau. Not at 
all common, and flies from March to July. The Saletara schoenhergi 
of Semper, described from Nias and South-East Borneo, also from Great 
and Little Nicobar in my collection, has been described and figured by
