a white tip. The male differs from the female only in having the apex of 

 the forewing more produced. 



Closely allied to G. decidia, Hewitson, and G. liamatus, Moore, btit 

 differing from Ceylon specimens of the latter in that the black mark- 

 ings on the upperside of both wings are far more restricted, and on the un- 

 derside of the hindwing much smaller and partially separated into spots. 



The specimen figured (a female) was taken at Khurda, Orissa, by Mr. 

 W. C. Taylor ; I have since received numerous males and females from 

 Bholahat in the Malda District, Bengal, where they were taken by Mr. W. 

 H. Irvine in the cold weather. There is also a single female specimen from 

 Sikkim in Mr. Otto Moller's collection. 



14. Castaltus ananda, n. sp. (Plate I, fig. 11, S ; 11«, ?.) 



Hab. Sikkim ; Kadur District, Mysore. 



Expanse : <?, -85 to 1-15 ; ? , '85 to 1-05 inches. 



Desceiption. Male. Upperside, both wings deep shining purple, 

 the outer margins black ; and with all the black markings of the underside 

 showing through by transparency in some specimens. Underside, fore- 

 wing sullied white, with the following black markings : — a basal streak, a 

 transverse streak from the middle of the costa to near the middle of the 

 wing, almost joined to another wider streak placed within it from the sub- 

 costal to the submedian nervure ; a very irregular discal series of four or 

 five oblong spots, an even submarginal series of seven spots, and a similar 

 but smaller series on the margin divided from the cilia by a very fine white 

 line. Hindwing with numerous spots placed irregularly over the whole 

 surface, and with the submarginal and marginal series as in the forewing ; 

 the spot, however, at the base of the tail, and the two confluent ones placed 

 within it irrorated with metallic greenish scales. Gilia dusky throughout ; 

 tail long, black with a white tip. 



I have only seen three specimens of this species, the male figured and 

 another one much smaller I took in the valley of the Great Runjit, Sikkim, 

 in October, 1882, the third was sent to the Museum by Mr. Kearney from 

 the Kadur District, Mysore ; the latter is much the largest specimen of 

 the three, and has the apex of the forewing more produced. All three 

 specimens differ slightly in the markings of the underside, but all undoubt- 

 edly belong to one sex of the same species. 



Since the above was written I took a male and a female also in the 

 Great Runjit valley in October, 1883, and have seen numerous specimens 

 from Sikkim in Mr. Moller's collection, including two females, which latter 

 differ from the male on the upperside in being pale dusky fuliginous, the 

 markings of the underside showing through even more prominently than 

 in the male, and the base of both wings thickly irrorated with metallic 

 blue scales. Underside as in tiie male.
