402 LYCASNID. CHARANA, 
A rare species in Sikkim, where I have taken it at a low elevation in October. It occurs 
both in the lower hills and in the Terai. Mr. A. V. Knyvett has taken it Jalpaiguri. The Rev. 
Walter A. Hamilton has obtained it in Sylhet, and at Gauhati in September, it has been 
recorded from the Khasi Hills, and there are specimens in the Indian Museum, Calcutta, 
from Buxa, Bhutan. 
The figure shews both sides of a male specimen from the Khasi Hills in my collection. 
I give below as foot-notes* descriptions of the genera Meocheritra and Jacoona, Distant, 
which occur in the Malay Peninsula. 
* Genus Neocheritra, Distant, Rhop. Malay., p. 252 (1885). ‘* Allied to Cheritva, Moore. HinpwinaG, 
with the costal nevuure terminating at about two-thirds of the costal margin, the sudcostal nervules emitted a 
little before the end of the discoidal cell, and the position of the faz/s reversed, the long one being at the 
apex of the submedian nervnre, and the shorter one at the apex of the first median nervule.” (Destanz, 1. c.) 
The diagnosis of this genus as given above seems to be very incomplete, as Mr. Hewitson states that 
the type species, VV. amzita, Felder, has four subcostal nervules to the forewing in the male, three only in 
the female, excluding the terminal portion of the subcostal nervure, which Hewitson never reckons as a 
subcostal nervule ; and in addition to the tuft of hairs on the forewing of the male that sex has a corres- 
pending cup-like depression on the hindwing. None of these important characters are present in Chevritra ; 
lt appears to me therefore that Meochevitra is a particularly good genus, and very distinct indeed from Chevitra. 
I have seen a female specimen only of one species of this genus, Mr. Distant places two species in it, one 
of which, 4. gama, Distant, has been described from a female only, and may therefore not belong to the genus 
at all, as I consider the presence or absence of secondary sexual characters in the male in the Lycenid@ usually 
of generic importance, and the male of 4. gama may not possess them, in which case the species would come into 
my genus Chavana. N. amrita is remarkable for the great length of the inner tail to the hindwing, which as 
figured by Mr. Distant is 1°2 inches long in the male, rather shorter in the female. In MV. gama it is “4 of an inch 
only in length. I amunable to give the geographical distribution of the genus, but it is probably confined 
to the Indo-Malayan region, There are several species figured by Mr. Hewitson which probably belong to 
it, but it would be extremely hazardous to venture to name them without having seen them.

half powdered with cerulean-blue. Aindwing with three anal lunules, and four spots of the anal margin 
whitish. UNDERSIDE, forewing and the apex of the Aindwing deep fulvous, the rest of the latter whitish, 
with blackish spots in two series in the anal region. FRMALE, UppPeErsipE, doth wings fuscous.’’ UNDERSIDE, 
both wings as in the male. 
“ Allied to WZ. [= Eooxylides) tharis, Hiibner, greater almost by half.” (Felder, |. c.) 
“This species differs in a remarkable way from the rest of the genus [J/y7iza apud Hewitson]. In 
the male, the inner margin of the forewing is rounded and projected outwardly, as in Exfl@a ; the middle of 
this margin has a tuft of long hair projecting from it at right angles, which covers a curious circular cup-like 
hollow spot on the opposite margin of the hindwing, the male has, besides this, a fourth branch from the sub- 
costal nervure of the forewing.” (H/ew7tson, |. c.) 
“ Mace. Urprrsipk, both wings violaceous-blue, more or less dusted with fuscous, Forewzng with the 
costal margin and rather more than the apical half black. A/ixdwing with the outer margin black, broadest 
at apex and containing three submarginal transverse pale spots, the two uppermost pale bluish, and separated 
by the second median nervule, the third white and situated between the first median nervule and the sub- 
median nervure, where above the black margin is also a pale greyish spot, and above the third median nervule 
there isa discal black fascia, anal angle white, containing a small black spot ; ¢a7/s greyish-white, with an 
indistinct medial pale fuscous line; tuft of hairs at base of inner margin of forewing greyish with an 
ochraceous tinge. UNDERSIDE, doth wings pale greyish. Forewing with the whole cellular anc outer areas 
pale reddish-ochraceous. Hindwing with the costal and apical areas pale reddish-ochraceous, with two series 
of black spots, one marginal and separated by the nervules commencing near the discoidal nervule, the other 
and preceding series consisting of three transverse spots separated by the first median nervule and the sub- 
median nervure ; fai/s with their bases blackish, and with a medial fuscous line. Body and /egs more or less 
concolorous with the wings. FEMALE. UpPEeRSIDE, 40th wings fuliginous-brown. Hindwing with the black 
and white markings at the anal angular area asin the male, but with the white markings larger, or sometimes, 
as in the figure here given, with the white area andthe black spots therein much larger ; ¢az/s greyish-white, 
with prominent medial fuscous lines. UNDERSIDE, doth wings as in the male. Aindwing with the black 
markings at anal angular area somewhat larger.” 
‘© The female figured is from Singapore and exhibits the maximum of varietal character as observed in the 
species, and which appears to be found in the extent of the black and white markings on the anal angular area 
of the upperside of the hindwing.’ (Distant, |. c.) 
There is a single female specimen of this species in the Indian Musuem, Calcutta, from Perak. Mr. Butler 
records it from ‘‘ Assam and Nepal,” but almost certainly in error.
