BUTTERFLIES FROM WE INDO-MALAYAN- REGION. 351 



his remarks, and a pair of which he kindly gave me. Regarded 

 superficially, these "Buxar" specimens might (specimens from other 

 localities being left out of consideration), by straining a point, in fact,, 

 be admitted to be a species distinct from the immensely common 

 Euthalia appiades, Menetries, of Nipal, Sikkim, Bhutan, Assam, &c. 

 The points on which Messrs. Swinhoe and Moore rely in distinguishing 

 these two species are that in the forewing, on both sides, in both sexes 

 the double discal band is contracted and approximates in the lower 

 discoidal interspace, and that inthe female it anteriorly expands beyond 

 that point, forming large white spots on both sides of the wings. 



To take the males first. E. sedeva is not a local race confined to 

 one particular locality, as Colonel Swinhoe admits that it occurs with 

 E. appiades at Buxar, and I possess- exactly similar specimens from 

 Sikkim on the west and from Cachar in. Assam on the east. The 

 contraction of the discal band is also characteristic of E. xiphiones, 

 Butler, which occurs to the south of Assam in Burma and in the 

 Malay peninsula. E. xiphiones may, however, be known in the male 

 by its broader blue border to the hindwing on the upperside. 



Then as to the females. Their characteristic feature is a white 

 discal macular band to the forewing much expanded anteriorly. I 

 have not ypical specimens of this form from Sikkim, where the females 

 of E. appiades appear to be very eonstant ; but directly one goes 

 east of Sikkim into the next State, Bhutan,, one finds all forms rang- 

 ing from t} r pical E. appiades to typical E. sedeva, as is also the case 

 in Assam and Burma. I maintain, therefore, that although extreme 

 specimens of E. appiades may be picked out and are typical E. sedeva, 

 that intermediates between the two forms occur, and that E. sedeva 

 cannot be maintained as a distinct species or even as a local race, as it 

 inhabits no restricted area as has been shewn above. 



In the Annals and Magazine of Natural History, sixth series, 

 vol. v, p. 354, n.2 (1890), Colonel Swinhoe describes i?. khasiana from 

 the Khasia Hills. He compares it with E. appiades, Menetries, but 

 says the blue coloration of the upperside of the hindwing in the male 

 is either confined to a " few greyish-blue scales on the outer margin 

 towards the anal angle," oris "obsolete" altogether, the latter form 

 being typical E. adima, Moore. In the Journal of the Asiatic Society 

 of Bengal, vol. lvii, part 2, p. 278, n. 6 (1888), I have at some length
