wings are bounded by a silvery cilia. Forewing marked near the costa with two small 
irregular dots of an intense black, Himdwing at the posterior angle [apex] with a large 
regularly circumscribed spot of the same colour, a minute dot is in some individuals obscurely 
perceptible near the anal angle. Zegs covered with lax villi of  silvery-white, tarsi 
surrounded by a black ring. Body brown above and white underneath. yes uncommonly 
prominent, and bordered with white. Axéenne brown, annulated with white. FEMALE. 
Wings somewhat broader. UppersipE, forewing, disc marked with a rhomboidal white 
patch, more intensely coloured exteriorly.” (Horsfield, 1.c.) Iam nearly sure Horsfield has 
mistaken a Meopithecops for the female of his Pithecops hylax, the markings of both sexes of the 
latter being alike. 
Dr. Horsfield notes that the LARVA in Java feeds on a leguminous plant. The PUPA as 
figured by him is very short and thick, pale ochreous-brown marked with dark brown, 
and as delineated these markings on the thorax assume the appearance of the face of a 
monkey, eyes, nose, nostrils and mouth. Dr. Horsfield states that he has ‘‘given the 
name of Fithecops* from the peculiar aspect of the chrysalis.” 
Occurs in Sikkim in March and October. It is found in heavy forest only, and has a 
weak fluttering flight, settling on the leavesof shrubs and plants. As has been noted in the 
habitat above, this species has a very wide range. Except Sikkim, Nias Island and Java, Mr. 
Doherty is responsible for all the other localities, in which he has personally met with it. 
The figure shews both sides of an example from Sikkim in my collection.

HABITAT: Margherita, Upper Assam. 
EXPANSE: & 92, 1'0 to I'I inches. 
DESCRIPTION: “MALE. UPPERSIDE, 40th wings black. Forewing with the discoidal 
cell, the interno-median interspace, and the disc of the Iower discoidal interspace, resplendent 
cyaneous blue in some lights, dull violet in others, the black border wide, extending one-third 
towards the base. Hindwing similarly blue from the lower subcostal nervule to the submedian 
nervure, the black border somewhat narrower, especially towards the anal angle; cz/éa of the 
hindwing whitish, except at the ends of the veins. UNDERSIDE, doth wings pure white ; a very 
slender dark marginal line, a narrow submarginal white band containing a line of six minute 
dark transverse streaks in the forewing and five [usually six] in the hindwing, within which isa 
narrow transverse ochreous-brown fascia very clearly defined (in the hindwing by an obscure dark 
line onits inner border), extending across the whole breadth of the forewing, and on the hindwing 
from the first subcostal nervule to the submedian nervure ; traces of slender discal streaks in the 
forewing near the lower angle within the ochreous band. Forewing with the apex obscured with 
black seales ; [two small costal black spots]. Hindwing with a large and conspicuous subapical 
black spot extending from the costa to the lower subcostal nervule. FEMALE. UPPERSIDE, 
both wings blackish. Forewing with the costa and outer margin darker ; cé/ia of the forewing 
pale, of the hindwing white. UNDERSIDE, doth wings as in the male.” 
‘* Margherita, where it perhaps takes the place of P. Ayl/ax, Fabricius. According to 
Mr. de Nicéville that species is in Sikkim much commoner than JVeofithecops, which I did not 
see in Assam at all. But in the Chittagong Hill Tracts, at Sandoway and Bassein in Burma, 
and in the Malay Peninsula, Pithecops is the rarer form, In Java it is Meopithecops that is rare, 
another instance of its close faunal resemblance to the Himalayas. In Celebes I did not ob- 
serve any Meopithecops, but a large protected Fithecops (P. phanix, Rober)t is very common 
and conspicuous. On the other hand, Weofithecops seems to occur alone in Malabar (where I 
found it as far north as the Gersapa Falls in North Kanara), and Ceylon, and alsoas far as my 
experience goes, in the islands of Lombok, Sambawa and Sumba east of Java.” 
‘* The genera differ in many important points. As regards prehensores, the clasp (harpago) 
of Neopithecops, seen from the side, is simply clavate at the tip, while that of Pithecops is long
