-cell, with eight smaller black spots round the cell placed one in each 

 interspace, of which the fourth, fifth, and seventh are smaller than 

 the others. Thorax and abdomen concolorous with the win^s. 

 Palpi (all except the short third joint which is deep black) bright- 

 ehrome-yellow. 



Though the female of this species differs so markedly in coloration 

 from its brilliantly snow-white male, I have no doubt whatever that 

 I have correctly paired the sexes. The position of the large spot at 

 the end of the discoidal cell of the forewing and the black spots on 

 the disc of the hindwing is the same in both, otherwise the sexes are 

 strikingly dissimilar in appearance. The palpi are bright chrome- 

 yellow also in both sexes, all except the terminal joint ; but the 

 thorax of the female is brown throughout, while in the male it 

 is anteriorly bright chrome-yellow. Mr. Doherty (1. c.) was evi- 

 dently perfectly correct in conjecturing that the female of this rare 

 butterfly would be " dark-coloured." 



Described from a single example in Mr. H. J. Elwes' collection 

 obtained by the Revd. Walter A. Hamilton's native collectors in 

 the Khasi Hills, Assam. Mr. Hamilton has given me three males 

 from the same locality. 



24. CELJENOERHINUS CLITUS, n. sp., PI. G, Fig. 2G, 6 . 



Habitat: Assam. 



Expanse: 6 , 2*2 inches. 



Description: Male. Upperside, both wings fuscous. Forewing 

 with the base overspread somewhat sparsely with yellow hair-like 

 scales ; three subapical dots, which form an oblique line whose inner 

 edge is straight, but the outer irregular owing to the spots varying 

 in size, the uppermost being oblong, and twice the size of the middle 

 smallest spot ; two small elongated spots divided by the lower discoi- 

 dal nervule placed below the subapical series and about co-equal in 

 size with the uppermost of these ; a large irregularly-shaped spot 

 across the discoidal cell at about two-thirds of its length from the 

 base, the inner edge of the spot straight, its lower half outwardly 

 produced, and therefore larger than the anterior half; a narrow out- 

 wardly-obliquely-placed spot in the middle of the second median 

 interspace ; a much larger one across the middle of the first median 

 interspace ; three spots in the subniedian interspace, the two anterior
