430 L. de Niceville & Dr. L. Martin —Butterflies of Sumatra. [No, 3, 
Java “ In not having a continuous fuscons [costal] margin to the fore¬ 
wing on the upperside, and in the greater amount of ochraceous colora¬ 
tion near the anal angle of the hind wing on the upperside.” (Distant). 
Found in Sumatra from near the sea to Soengei Batoe on forest roads, 
where it settles with wide-spread wings on moist places and by the side 
of small pools; if pursued it settles on the underside of leaves by the 
roadside. On the wing when flying rapidly along a forest road in search 
of moisture it may easily be taken for a pierine butterfly. All the 
butterflies of this genus in India are well named “ The Map ” from 
their characteristic markings and coloration.

Forbes. Staudinger as 'msenalis , var. sumatrensis. Semper as 
msenalis. I have redescribed this species in Journ. Bomb. Nat. Hist. 
Soc., vol. vi, p. 358, n. 11 (1891). It occurs in the hills of Perak 
in the Malay Peninsula at 3-4,000 feet elevation. C. msenalis , Ericlison, 
is a distinct species, and is found in the Philippine Isles. From the 
point where G. nivalis , Felder, no longer occurs, at Soengei Batoe 
and on the higher mountains and the Central Plateau, this beautiful 
and very distinct species is found commonly throughout the year. It is 
somewhat smaller than C. nivalis. The liattak collectors report that 
it comes down to the small hill streams in crowds with numerous 
Pierinse to suck up the moisture.

Grose Smith. Staudinger. This beautiful species occurs only 
on the western boundary of our area at higher elevations. Herr M. Ude, 
the European collector of Dr. H. Dohrn, took some thirty specimens 
near Boliorok in May, 1894. Dr. Martin obtained his first specimens 
from Kepras in January, 1895, and also a single example, perhaps a 
straggler to the south-east, from the Karo mountains in December, 1894. 
Dr. Martin has caught it himself on the Penang Hill, or “ The Crag.”

Dr. Martin obtained a single specimen in May, 1893, from the 
forest near Selesseh, caught by a very clever and intelligent Chinese 
collector. Mr. de Niceville recogmised it at once as a species new to 
science, and at Dr. Martin’s request named it in honour of H. R. H. 
Princess Therese of Bavaria, who is well-known by her valuable
