on the Central Plateau at an elevation of not less than 3,000 feet at 

 least. It is quite common where it is found, and is endemic to the 

 Battak mountains.

M. dohertyi, Elwes, Proo. Zool. Soo. Lond., 1891, p. 261, pi. xxvii, fi^s. 3, male ; 

 4, female. 



Described from Perak in the Malay Peninsula. Dr. Martin obtain- 

 ed a single male from Selesseh, and later a female from Soeka- 

 randa, and in 1894 one pair from Bekantschan. It is one of the rarest 

 butterflies in Sumatra, as in thirteen years' collecting he only obtained 

 these four specimens. 



63. *Mycalesis (Mydosama) asophis, Hewitson. 



Grose Smith. Originally described from Mysol. Recorded also 

 from New Guinea, Waigiou and Ternate by Moore. Unknown to us. 



64. Mtcalesis (Loesa) oeoatis, Hewitson. 



Hagen as oroatis and ustulata. Mr. F. Moore allows L. surlcha, 

 Marshall, to stand for this species, in preference to L. fervida, Butler, 

 which is an older name, being the first published. Colonel Marshall's 

 description of M. surkha was read before Mr. Butler's paper was pub- 

 lished, but that does not give priority. M. fervida, M. surkha and 

 M. ustulata, Distant, are all synonyms of M. oroatis, described from Java. 

 The first two names represent dry-season, the last two wet-season forms 

 of one and the same species. The dry-season form certainly does not 

 occur in Sumatra, it is unknown to me if it is found in Java. M. oroatis 

 is somewhat uncommon in the lower hills at Namoe Oekor, Namoe 

 Tambis, and Bekantschan. It is the darkest of the yellow species of 

 Mycalesis found in Sumatra. Females are rare. 



65. *Mtcalesis medusa. 



Grose Smith. This species does not appear to liave ever been 

 described. 



66. *Mycalesis bockii. 



Grose Smith. Also apparently nondescript. 



It may perhaps be here noted that all the Sumatran species of 

 Mycalesis are very earth-loving insects, they always keep close to the 

 ground, which they only leave for higher flights on two occasions, viz., 

 during the wedding flight, and when two jealous males meet and fight. 

 Mycalesis are out on rainy days when there is no sun, and give on such
