where these two places are, through Pooneh may be Poonch, which is a small State on the outer 
ranges bordering the plains. It has not been received by me from the Nicobar Isles, but occurs 
in the Andamans. Ifthe M. aluta of Druce is, as I suspect, synonymous with JV. ardates, then 
it occurs in the Malay peninsula and Borneo, and I have received the true MV. ardates from 
the Philippines from Herr Georg Semper. It is the smallest and commonest species of the 
genus.

DESCRIPTION : ‘‘ MALE. UPppPersIDE, both wings violet-blue, with the outer margins 
evenly narrowly black. UNDERSIDE, doth wings fawn-coloured. Forewing with a white- 
bordered dusky spot in the middle of the cell, a similar one at its end, a discal chain of six 
similar spots, the two lower ones out of line, (in some specimens the sixth lowest spot is. 
absent) ; submarginal and marginal indistinct series of pale lunules. Aindwing crossed by 
three much broken bands of white-bordered dusky spots, and submarginal and marginal 
lunules as in the forewing ; two small black spots at the anal angle on the margin. Cz/ia 
dusky throughout. FEMALE. UPPERSIDE, forewing black, the disc whitish and covered 
with pale blue metallic scales, the disco-cellulars marked witha black spot. Aindwing 
dusky, with pale bluish-white streaks between the nervules, a black disco-cellular spot, and 
obscure marginal pale lunules. UNDERSIDE, doth wings cream-coloured, the markings as in 
the male, but all the spots and bands (except the two black anal spots) pale ochreous.” 
“Two male specimens were taken in the Sikkim Terai in July and August, 1881, by 
Mr. Otto Miller, and four males from Bhurkhul and one from Demagiri in the Chittagong 
district were taken by Mr. H. M. Parish in February, 1883. All these specimens are very 
constant, showing no variation whatever. They present a superficial resemblance to 
N. ardates, Moore, but are a different colour on the upperside ; they have also no tail, and 
should therefore probably be placed in a different genus.* Mr. Otto Moller has also obtained 
numerous males at low elevations in Sikkim during the summer and autumn, including the 
female described, Mr. W. H. Irvine has sent it from the Malda district, the Calcutta Museum 
collector took it at Buxa, and I took it inthe Great Runjit valley, Sikkim, in October.” (de 
Nicéville, 1. c.) 
** Not socommon as WX, ardates, Moore. It is quite different from the tailless MW. ardates 
of Orissa, the hindwing being broad and truncate.” (Doherty, 1. c.) Occurs in Sikkim in 
June, October, November and December. Mr. Otto Moller possesses three female specimens, 
which differ somewhat in the extent of the bluish-white coloration of both wings on the 
upperside ; in the prominence or otherwise of the markings, and in the shade of the ground- 
colour, on the underside. 
Colonel Lang reports M. dana as “rare at Naini Tal, 5,500—6,500 feet, May; Kosi 
Valley, Kumaon, 3,200 feet, July; Ranibagh, plains, 1,000 feet, October.” Mr. Hampson 
reports (1. c,) that it occurs commonly in the Nilgiri Hills from 2,000 to 4,000 feet elevation.

* I have since examined the venation of this species, and as it does not differ in the smallest particular 
from that of VV, avdates, Moore, I do not now think that it should be placed in a different genus.
