fore wing quite or almost obsolete ; whilst 1 from Bhutan (named 

 sahadeva by Col. Swinhoe), 3 from Cachar, 1 from Khasia, 1 from 

 Burmah, 2 from Tenasserim, and 4 from the Karen Hills have the 

 whitish band more or less well marked, and the apical patches distinct 

 and well defined. Two species might very well be made ef the 

 female sex, but as both forms are found in the central part of its 

 range I should rather consider it as a case of sexual dimorphism. 



EUTHALIA JAHNU. 



Adolias jahnu, Moore, Cat. E. I. C. p. 192 $ ; Butt. Ind. ii. p. 211. 



Adolias sananda, Moore, Trans. Ent. Soc. 1859, p. 7G, t. vii. 3 S . 



One male and three females from the Naga and Karen Hills ; the 

 latter are rather smaller and paler than those from Sikkim and 

 Khasia. 



EUTHALIA KESAVA, Var. DISCISPILOTA. 



Adolias ditcispilota, Moore, P. Z. S. 1878, p. 831, t. lii. 2 ; Butt. 

 Ind. ii. p. 213. 



Though the form found in the Karen Hills and Tenasserim is 

 smaller and slightly different in the markings from kesava of Sikkim 

 and the Khasias, I hard!)' think it can be treated as a distinct species ; 

 the male in this case is more different from kesava than the female, 

 which is almost identical. 



Athyma nefte, var. nivifera. 



A. nivifera, Butl. Trans. Linn. Soc, 2nd ser. Zool. i. p. 540, t. 69. 

 4(1879). 



A. nefte, var. nivifera, Dist. Rhop. Mai. p. 163, t. xvi. 6, 7. 



A single male from Perak has the white band above suffused and 

 edged with blue. I follow Distant in treating it as a variety of nefte, 

 not having the material which would allow me to judge for myself. 



Athyma kbesna. 



A. kresna, Moore, P. Z. S. 1858, p. 12, t. 1. 4 (5. 



A male from Perak agrees with one in my collection from Sumatra. 



Athyma sulpitia.

A. sulpitia. Butt. Ind. ii. p. 174. 



A specimen from Bhamo, collected by Major Adamson, agrees 

 with Chinese examples from Ningpo and the valley of the Yang-tse- 

 kiang. 



Athyma selenophora. 



Limenitis selenophora, Koll. Hiigel's Kash. iv. p. 426. 

 A. selenophora, Butt. Ind. ii. p. 176. 



Two pairs from the Karen Hills, of which the females are much 

 smaller than any of my Indian specimens.
