mine the first male obtained by me, which I took to him on paying 
my first visit to Darjiling, after I had had the animal returned to me 
as undeterminable from Berlin. Afterwards I sent collectors especially 
to the mountains to obtain females, when de Niceville’s identification 
was splendidly confirmed. As far as I am aware, no specimens from 
Java, from whence this species was first obtained, have been recorded 
since the female was described by Dr. Felder. L. darena is doubtless 
one of the rarest, as well as one of the most beautiful, if not the most 
beautiful, species in this large genus.” 
76. Lethe europa, Fabricius. 
Snellen. Hagen as europa and arete. Distant. Occurs in nearly 
the same localities as L. mekara , Moore, and has the same habits but is 
considerably rarer, especially the female. Dr. Hagen records both 
L. europa and L. arete , Cramer, from Sumatra. The latter, according to 
Mr. F. Moore, is found in the Sula islands and Amboina only, while 
L. arcuata , another allied species described by Butler, is confined to 
Celebes. 
77. Lethe rohria, Fabricius. 
Snellen. Hagen. A common species, but confined to the Central 
Plateau of the Battak mountains. 
78. # Ypthima ceylonica, Hewitson. 
Elwes. Unknown to us from Sumatra. It occurs on the eastern 
coast of India (Orissa and Ganjam), in South India, and in Ceylon. 
79. Ypthima baldus, Fabricius. 
Hewitson. Grose Smith. Hagen as methora , Fabricius [sic]. Elwes. 
Probably the commonest species of Ypthima in the plains and found 
everywhere. The larva feeds on the same ubiquitous Graminece as 
Mycalesis mineus , Linnaeus. Dr. Hagen evidently followed Mr. W. L. 
Distant in Rhop. Malay., who described and figured this species erro¬ 
neously under the name of Y. methora , Hewitson. No species of Ypthima 
presents dry-season forms in Sumatra, all are strongly ocellated.

figs. 7, male; 8, female (1895). 
Very rare, in all Dr. Martin has not obtained more than a dozen 
specimens. It is of large size, 1'6 to 1‘8 inches in expanse, and has five 
ocelli only on the hindwing, a pair at the anal angle, a pair in the 
median interspaces, and a single one in the upper subcostal interspace.
