52. LYCENID. NEOPITHECOPS. 
before the apex, fi [upper discoidal] from the end of the ‘cell ; disco-cellular nervules very 
slender, miadle disco-cellular slightly longest, nearly straight ; discoidal cell long, broad ; second 
median nervule emitted at one-sixth before the end of the cell, firs¢ median at nearly one-half 
before its end; sudmedian nervure straight. HINDWING, small, very broad, oval; exterior 
margin very convex ; costal nervure arched at the base, extending to the apex ; first subcostal 
ner vule emitted at one-fourth before the end of the cell; disco-cellular nervules very slender, 
upper disco-cellular curved outwards, ower disco-cellular curved inwards ; discotdal cell broad ; 
third and second median nervules emitted from the end of the cell, /rs¢ median at one-third, 
before its end; sudmedian and internal nervures straight. Bopy slender; palpi porrect, 
slender, clothed with short lax scales, second joint laterally compressed, long, projecting 
half its length beyond the head, third joint about half its length, longer in the female, 
slightly clavate at the tip in the male and cylindrica! in the female ; /egs slender, 
fore tarsi composed of five joints, laterally spined, and in the male with a terminal bifid claw and 
in the female with a blunt claw ; anfenne witha well-formed lengthened spatular club.” 
(Moore, 1. c. in Lep. Cey.) ; 
In the forewing the costal nervure terminates before the end of the cell, the first subcostal 
nervule terminates just beyond its end, the base of the second subcostal is rather nearer to the 
base of the first than to that of the upper discoidal, the third subcostal is emitted about midway 
between the base of the upper discoidal and the apex of the wing; the eyes are naked. 
““This genus is quite distinct from Pithecops, Horsfield, (of which the type is the Javan 
species P. hylax, Fabricius), although similarity in colouring and markings has led to consider- 
able confusion. In Piéthecops the first subcostal nervule is distinctly and strongly anastomosed 
with the costal nervure, in Meofithecops that nervule is quite free and situated some clear 
distance from the costal nervure.”’ (Déstazt, |. c.) 
As far as I am aware, Neopithecops occurs only in India, Ceylon, the Andaman Isles, in 
Burma, and the Malay Peninsula, though Herr Rober has described what is probably a species of 
this genus (Iris, vol, i, p. 61, pl. iv, fig. 5 (1886) from the Aru and Key Islands under the name 
of Plebeius lucifer. Mr. Doherty notes that “ WV. zalmora is commoner than Pithecops hylax, 
Fabricius, at Mergui and Myitta, Burma, and_ occurs in Java and Sumba, but is rare 
in both. It is common from the Chittagong Hill Tracts to South-Eastern Borneo.” 
With regard to the described species from the Indian region, I recognise only one as 
distinct. Mr. Distant says that there is an undescribed form from the Andaman Isles, 
Mr. Moore proposes to name the form occurring in the Nilgiri Hills 4. ¢odara, which with the 
four already described makes six in all, All these species appear to me to owe their origin to the 
want of appreciation of the great extent of the seasonal dimorphism which obtains in them, at any 
rate in those districts where there are two well-marked seasons, a dry anda wet. The darkest 
ofall is M. horsfeldi, Distant, described from a single male specimen from Singapore ; this form 
has no white whatever on the upperside, and may be constant in the Malay Peninsula, where 
it rains, I believe, almost throughout the year, so that there is no distinct dry-season. 
This form is found in Calcutta, in the Malda district, and doubtless elsewhere during 
the rains. V. 2a/mora is said to have a small white patch on the dise of the forewing, none 
on the hindwing, as also have JV. /uct/er, Rober, and the form which occurs in the Andamans. 
N. dharma has small patches on both wings. Mr. Butler in naming the former species gave no 
habitat for it, but Mr. Moore has recorded it from the N.-W. Himalayas (not improbably these 
specimens were some from Calcutta L sent Mr. Hocking, and which he omitted to label), and 
writes me that it occursinthe Calcutta district; W. dharma comes from Ceylon. 2. gaura 
has the white patches the largest of all, occupying more than half the upper surface of the 
wings. Mr. Moore described it from Calcuttaand Assam, but it occurs in the Malda dis- 
trict and in Orissa as well, and doubtless elsewhere. It is found in the middle of the dry- 
season in Calcutta, and also differs from the wet-season form in having all the markings of the 
underside more or less obliterated. The MS. species ¢odara from the Nilgiris has the patches 
of moderate size as in V. dharma, The Andaman form might perhaps be considered distinct
