152 LYCAINIDAS. NACADUBA., 
EXPANSE: @, 1:00 to I'I5 inches, : 
DESCRIPTION: ‘‘MALE, Upperstpr, doth wings shining bluish-purple, the outer 
margins somewhat widely black. Himdwing witha fine white anteciliary line from the anal 
angle to the first median nervule. UNDERSIDE, both wings dusky. Forewing with a 
subbasal straight fascia from the subcostal nervure to the inner margin darker than the ground- 
colour, and margined with white ; a similar fascia from near the costa to the inner margin 
enclosing the disco-cellular nervules, and a series of five similar spots forming an out- 
wardly-curved band from the costa to the second median nervule ; a submarginal series of 
dusky spots outwardly narrowly and inwardly widely defined with white ; an anteciliary 
fine white line. A¢zdweng with three indistinct basal spots, a subbasal straight band, 
another across the disc, coalescing with a shorter much curved one beyond, and enclosing a con- 
spicuous small oblong white spot, marginal markings as in forewing, but witha round 
black spot beyond the origin of the tail, outwardly defined with silvery-blue scales and in- 
wardly with an orange line, and with a few similar scales towards the analangle. Cz/ia dusky, 
as is also the /a7/, the latter tipped with white.” (de Wicévelle, 1.¢.) 
This species is quite unmistakable for any other known to me. It has a wide range, 
from Kumaon to Upper Assam, reappearing inthe Andaman Isles. It is strange that out 
of the very numerous male specimens I have received there should be not one female; this 
is probably to be accounted for by the males having been captured near water, and in the 
open, while the females keep to the bushes and thick forest. 
The figure shews both sides of a rather lightly-marked male specimen from Cachar now 
in the Indian Museum, Calcutta.

DescripTION: “MALE. Differs from Sikkim specimens of WV. ardates, Moore, in being 
larger, the band crossing the middle of the cell on the UNDERSIDE of the forewzng in N. ardates 
not extending below it in M. é/z¢ea, and the lower spot of the discal series well retired from the 
line of the five spots above it, whereas in 4. avdates there are two lower spots out of line, one 
being additional.” 
“I took asingle specimen on the Darjeeling cart-road between 2,000 and 5,000 feet elevation, 
in October, 1880, and numerous specimens have since been taken in Sikkim at low elevations. 
It seems a constant and well-marked species. ” (de Nzcévzile, 1. c.) 
“This species, though very close to V. ardates, may be distinguished without difficulty, 
if fresh specimens are compared. The best character is in the lower spots of the discal series 
on the forewing below, which form a bar right across the wing in WV. ardates, andin NM. bhutea 
are less in number, and do not reach the hind margin. De Nicéville says truly that the band 
crossing the middle of the cell on the forewing below does not extend below it in NM. dhutea, 
and, though in MV. ardaées it usually does, yet I find some specimens in which this bar is 
variable in length.” 
‘* NM. bhutea is not so common as NM. ardates, and, like it, frequents wet sandy spots in 
the beds of rivers at 1-3,000 feet. I took it below Mongpo in June, and Moller gets it from 
April to October.” (Z/wes, 1. c.) 
In speaking of M. ardates, Moore, Mr. Butler notes on some specimens collected *‘ near 
Assam” that ‘* four damaged males were obtained, no two of them absolutely alike in the 
pattern on the underside of the forewing, A nearly allied ‘species’ described by de Nicéville, 
is separated from the above [WV. ardates] by its superior size, by the abbreviation of the band 
crossing the cell [of the forewing] on the underside, and by the absence of the lowest spot in the 
discal series. The specimens before me vary from 22 to 24 millim, [= ‘go to 95 ofan inch] in ex- 
panse of wing ; the band is only abbreviated in one of the larger specimens, and, though all have
