442 LYCALNIDAS. DRINA. 
Genus 166.—DRINA, nov. (PLATE XXIX). 
FOREWING, costa somewhat strongly and regularly arched, afex acute, outer margin 
slightly concave, ier margin slightly sinuous ; cosfal nervure ending on the margin consider- 
ably beyond the apex of the discoidal cell ; second subcostal nervule with its base equi-distant 
between the bases of the first subcostal and upper discoidal nervules ; ¢hivd subcostal long, 
originating about midway between the apices of the cell and of the wing ; terminal portion 
of subcostal nervure reaching the extreme apex of the wing ; xfer discoidal nervule originating 
immediately before the apex of the cell ; middle and lower disco-cellular nervules upright, 
slightly concave, the lower a little the longer ; second median nervule originating some distance 
before the lower end of the cell ; swbmedian mervure nearly straight. HINDWING, costa arched, 
apex rounded, outer margin nearly straight to the base of the tail, then at right-angles to anal 
angle, abdominal margin recurved ; costal nervure curved throughout its length ; first szdcostal 
nervule originating far before the apex of the cell ; upper disco-cellular nervule straight, out- 
wardly oblique ; ower disco-cellular concave, upright, a little longer than the upper ; second 
median nervule originating a little before the lower end of the cell ; swbmedian nervure straight 5 
internal nervure rather long, recurved. Antenne short, much less than half the length of the 
costa of the forewing, with a gradually-formed, rather long, slender club. Zyesnaked. Palpé 
porrect, reaching to about the middle of the eyes, clothed with adpressed close scales. Body 
moderately robust. 7zz/ rather short, less than one-third of an inch in length, rather broad, 
placed at the termination of the first median nervule. Type, A/yriza donina, Hewitson,. 
Drina is perhaps nearest to Cheritra, Moore, from whichit may at once be known by 
the much shorter single tail to the hindwing, the absence of an anal lobe, the disco-cellular 
nervules more upright ; in the forewing by the costal nervure being much longer ; the palpi 
are also much shorter. My knowledge of the genus is derived from a single female specimen 
of the type species, which is so unusual in appearance on both surfaces, and moreover so very 
different in structure from its apparently nearest ally, that I have no doubt that it constitutes 
the type of a very good genus. The genus contains possibly three species, two of which are 
included in this work, and occur in Burma and the Malay Peninsula, the third is the AZyrina 
mavortia of Hewitson, which was described from Mindanao, one of the Philippine Isles.

DESCRIPTION: “MALE. UPPERSIDE, 60th wings fuscous. Aindwing ciliated with dull 
whitish, the external border darker, adorned with two series of whitish spots, the inner one 
bent, the outer one incomplete. UNDERSIDE, d0/h wings silky whitish, a blackish-fuscous 
line before the cilia, a striga beyond the disc, straight in the forewing, wavy in the hindwing, 
another external broader, marked on the hindwing with a black subanal spot, and a third 
obsolete before the margin, hoary-fuscescent. orewing with the internal border hoary- 
fuscescent. AMzndwing with a black anal spot circled with hoary and fuscous.” 
‘* This not less remarkable insect belongs, as does the preceding [A/yrina discophora, Felder, 
from the Philippines] to the neighbourhood of JZ. maneia, Hewitson” [see foot-note, p. 443].
