453. Tajuria thru, de Niceville. 



T. thria, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. x, p. , n. 26, pi. T, 

 figs. 38, male; 39, female (1896). 



Found in Tenasserim, Burma, and the Battak Mountains south 

 of Bekantschan, Sumatra, in March, May and July. It is rare, and 

 may easily be distinguished from its allies by the male being entirely 

 black on the upperside of the forewiug. 



454. Tajuria blanka, de Niceville. 



T. blanka, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 39, n. 34, pi. iv, 

 fig. 4, female (1894). 



Two females of this very rare species have been obtained in the 

 higher mountains ; the type specimen in October, 1893. 



455. Tajuria donatana, de Niceville. 



Originally described from Burma. Two male specimens only 

 have been obtained in March and July at Bekantschan at the foot 

 of the Battak mountains in Sumatra. This species is quite distinct 

 from the Celebesian species, T. orsolina, Hewitson, to which it is 

 nearly allied. 



456. Ops ogyges, de NiceVille. 



0. ogyges, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. ix, p. 298, n. 25, 

 pi. P, figs. 36, male ; 37, female (1895). 



Originally described from Maulmain in Burma. Vei'y rare, Dr. 

 Martin obtained one male specimen in the Battak mountains in Sep- 

 tember, 1891, which I have not seen. 



457. Ops melastigma, de Niceville. 



In 0. ogyges, de Niceville, the "male-mark" on the disc of the 

 forewing on the upperside is indistinct, and can be seen only in certain 

 lights. In 0. melastigma it is exceedingly prominent, quadrate, and 

 dingy black or fuliginous in colour. It is very rare in Sumatra, Dr. 

 Martin possesses a single male taken in the Battak mountains in 

 December. 



458. Brltomartis cleoboides, Elwes. 



B cleoboides, de Niceville, Journ. Bomb. Nat. Hist. Soc, vol. ix, p. 306, n. 1 (1895). 



Messrs. Grose Smith and Kirby have both recorded Tajuria isseus 



Hewitson (see No. 452) from Sumatra, but probably the specimens so 



identified should be the present one, which has only recently been 



described. The true " Iolaus" isseus, the type specimen of which was
