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 edropa, Fabricius. 



Snellen. Hagen as euro-pa 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. *Tpthima ceylonica, Hewitson. 



Elwes. Unknown to us from Sumatra. It occurs on the eastern 

 coast of India (Orissa and Granjam), 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 Gramineai as 

 Mycalesis mineus, Linnasus. 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. 



80. Ypthima urba, de Niceville. 



7. iarba, de Niceville, Journ. Bomb. Nafc. Hist. Soc, vol. x, p. 18, n. 4, pi. K, 

 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, P6 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.
