27G L. de Niceville — New Butterflies from the Indian Begion. [No. 4, 



4. Neptis nana, n. sp., PL XIII, Fig. 1, ^ , 

 Habitat : Bhutan. 



Expanse : cf , 2*5 inches. 



Description : Male. Upperside, hotli wings distinguished from N. 

 narayana, Moore,* by having all the markings bright ochreous instead 

 of ^'ptcre ivhite," as described and figured by Mr. Moore for that species, 

 or just very faintly tinged with palest ochreous, as in the specimens 

 I have seen. Hindwing with the submarginal band narrower. Under- 

 side, both wings with the ground-colour and pale violet markings of a 

 deeper and richer shade of colour. Hindiving with the submarginal 

 band as above narrower, the pale violet band between it and the discal 

 band broader and better- defined, and the marginal pale violet line nearer 

 the margin. 



There are three male specimens of N. 7iana in the collections of 

 Messrs. Otto MoUer and A. V. Knyvett taken in April and June by 

 their native collectors in Bhutan. The rich ochreous coloration of the 

 markings of the upperside will at once distinguish N. nana from N. 

 narayana. The range of the latter species has been considerably ex- 

 tended by Colonel A. M. Lang, R. E,, taking it at Naini Tal rarely at 

 from 5,500 to 6,500 feet elevation in the middle of May. N. nana is also 

 allied to " Limenitis " antonia, Oberthiir,t from Moupin, from which it 

 may be known, on the upperside of the forewing, by the discal streak 

 being shorter, and the lower portion of the discal macular band (in 

 N. antonia formed of four spots at regular intervals divided only by 

 the veins, in N. nana apparently of two spots only, with a considerable 

 space of the ground between them, the upper spot nearly a circle, 

 the lower an elongated streak) differently shaped. On the hindwing 

 the submarginal yellow band in N. nana is narrower. It is also more 

 distantly allied to " Limenitis " armandia, Oberthiir,| described without 

 exact locality as from China, but the extreme tenuity of the yellow 

 markings on the upperside of both wings in that species will at once 

 distinguish it from N. nana ; the markings of the underside are similar 

 in character, but those on the hindwing are much blurred, and the 

 ground-colour is pale yellow almost throughout. N. nana is also allied 

 to N. thisbe, Menetries,§ a species that has no yellow submarginal band 

 on the upperside of the hindwing, and occurs in Amurland.
