 Subfamily Satyrtn-E. 



48. Mycalesis (Satoa) maia, de Niceville. 



M. (Satoa) maia, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 1, n. 1, pi. i, figs. 

 1, male; 2, female (1894). 



Grose Smith as maianeas. Snellen as majaneas [sic]. Hagen as 

 maianeas. Occurs only in the large forest, and never at low elevations, 

 its region commencing at Namoe Oekor and thence into the hills. It 

 is always found on or very near to the ground. Very easily damaged, 

 hardly ever is a perfect specimen obtained. 



49. *Mycalesis (Dalapa) sudka, Felder. 



Moore. Not rare in Java, unknown to us from Sumatra. 



50. Mycalesis (Suralaya) orseis, Hewitson. 



Gi'ose Smith. Hagen. Snellen. Kirby. Distant. Also a true 

 butterfly of the high forest, and is the only Sumatran Mycalesis which 

 has a bluish gloss on the upperside of the wings as so many forest butter- 

 flies have in a greater or less degree, such as the Ccelites, Thaumantis, Ama- 

 thuxidia dllucida, Honrath, and others ; even the Lampides of the forest, 

 L. saturata, Snellen, L. elpis, Godart, and L. subdita, Moore, are far 

 richer and deeper blue than the Lampides celoio, Cramer, of the roads. 



51. Mycalesis (Orsotriaena) medus, Fabricius. 



Hewitson as hesione. Snellen as hesione. Grose Smith as hesione. 

 Hagen. Distant. Very common in the plains. The dry-season form of 

 the species found in many parts of India, M. runeka, Moore, is quite 

 unknown in Sumatra. Dr. Martin has bred it in Sumatra on grass, 

 from eggs laid by females shut up in glass prune bottles. He considers 

 that Orsotrizena should be used in its full generic sense, as the larva and 

 and pupa differ greatly from the larvae and pupa? of species of Galysisme 

 and Mydosama which he has also bred from the egg laid in confinement, 

 the larva? of these subgenera also feeding on various species of grass. 

 M. medus in Sumatra occurs all the year round, generation following 

 generation in rapid succession. Dr. Martin notes that " The ocelli on 

 the underside of the wings possess in this species a quite peculiar glossy 

 surrounding, which I know to occur only in the Indian genus Zipoetes, 

 Hewitson." 



52. Mycalesis (Calysisme) perseus, Fabricius. 



Grose Smith as samba and lalassis. Hagen as blasius, var. lalassis, 

 Hewitson. M. blasius is the wet-season, and M. perseus the dry-season
