NV. plumbeomicans comes into quite a different group from M. macrophthalma, from which 
it is of course abundantly distinct, having an extra fascia or rather two extra strigc to the fore- 
wing on the underside, but it is very near to Ceylon specimens of WV. prominens, Moore, from 
which it differs in its slightly paler coloration on the upperside in the male, rather broader 
forewing, the outer margin less oblique, the inner margin longer. The markings on the under- 
side are precisely similar, being narrow and clearly defined, the edges of the whitish fascize not 
at all blurred. The female is less variable than that sex of V. prominens, the metallic blue 
patch on the upperside of the forewing being always small, while in V. Arominens it varies 
very greatly in size. 
NV. plumbeomicans was taken by Dr. Anderson in considerable numbers in the Mergui 
Archipelago during the cold weather, there is asingle male specimen from the Chittagong 
Hill Tracts in the Indian Museum, Calcutta, and in the Andamans it appears to be a common 
species. 
Local race xécobaricus, ‘‘ MALE. UNDERSIDE, doth wings purplish slate-colour, the 
marginal and suomarginal macular fasciz more distinct, iron-grey, narrower, and separated 
by a wider space of the ground-colour from the discal fascia, in having all the fascize more 
sharply defined ; and in having a very much larger subanal black spot, which is more broadly 
encircled with brighter orange, on the Ainzdwing, than in WV. plumbeomicans.” (Wood-Mason and 
de Niceville, 1.c., Journ. A. S. B., vol. 1.) 
This local race occurs on Kamorta and Katschall in the Nicobar Isles, and seems to be 
rare. I have only seen four specimens in all. 
Two other species of this group occur in the Malay Peninsula, their descriptions will be 
found below.* Without specimens of them for comparison with the Indian species, it is quite 
impossible for me to give any distinguishing characters,

DESCRIPTION: ** MaLE. UpPERsIDE, doi wings of a leaden-violet tint, with a black-fuscous anteciliary streak, 
Unpbersipk, both wings of a pale hoary-brown colour, with fuscous macular double fasciz, margined with 
white, and closely touching one another along the margin of the wing. Forewing with the following fascia <— 
One subbasal almost touching the costa, then a subcostal spot, a short disco-cellular fascia, an exterior chain- 
like fascia broken at the second median nervule. A/indwing with a basal fascia, adisco-cellular fasciole, and 
‘an exterior fascia contiguous at the second median nervule, anteriorly twice strongly broken, and posteriorly 
broken, chain-like, of the colour of the ground, [all] laterally surrounded with fuscous and margined with 
white ; also a posterior spot, which is orbicular, inwardly girt bya yellowish circle, outwardly divided by a 
delicate metallic bow, it has alsoa pair of minute black anal spots which have inwardly a narrow border 
of a metallic yellowish tint.” - .

‘* This species seems to be very closely allied to WV. atvata, Horsfield, and so again with the equally 
similar form described as NV. frominens, Moore. Horsfield’s species, however, appears to be distinct by the 
colour pattern of the wings of the female ‘ transmitting a white patch on the disc.’ ” (D/stant, 1. c.)

This description is absolutely worthless, and till this species and others described by Mr. Druce are re- 
described, they will never be recognised. The figures are equally bad. On the single page where WV. 
a/mora is described, five other “ new species” are also described in from three to six lines apiece, Mr, Distant 
figures this Species without tails. ; :
