310 LYCANIDA. EUASPA. 
HINDWING, short, very broad, exterior margin convex and slightly sinuous, with a single 
slender ¢ai/ from the end of the first median nervule ; costa/ and subcostal nervures joined toge- 
ther at their base, the former much arched from the juncture ; désco¢dal cell broad, extend- 
ing to half length of the wing; first subcostal nervule emitted at one-fifth before the end of 
the cell ; disco-cellular nervule very slender, erect ; discotda/ nervule from near its middle ; 
second and third median nervules from the end of the cell, #s¢ median at one-third before the 
end ; submedian nervure curved ; internal nervure short, recurved. Bopy, short ; Aa//z porrect, 
second joint long, extending half beyond front of the head, pilose beneath, third joint slender, 
one-fifth as long as the second; /egs slender; avtenne thickened at the end, tip blunt.”

The above diagnosis appears to me to give a very erroneous account of the neuration 
of this genus, which is somewhat peculiar. The second subcostal nervule of the forewing 
most certainly is not bifid, if any it is the third ; nor do I understand how Mr, Moore makes 
the fourth and fifth subcostal nervules originate from the end of the cell. He only describes 
one disco-cellular nervule in each wing with the discoidal nervule from its middle, of course 
there are two, in the forewing the lower discoidal, in the hindwing the single discoidal nervule 
originate from their point of junction. In the hindwing there is nothing peculiar about 
the costal and subcostal nervures being joined together at their base, it is a common feature 
for these two veins to run side by side for some little distance from the base of the wing 
before they take different courses ; the disco-cellular nervules are not erect, but outwardly 
oblique. I should describe the neuration as follows:—In the forewing the costal nervure 
terminates opposite the apex of the discoidal cell; the first subcostal nervule originates at 
about two-thirds of the length of the cell from the base; the second subcostal originates 
half as near to the origin of the middle disco-cellular as to the base of the first subcostal ; 
the third subcostal is short, originates nearer to the apex of the wing than to the base of the 
upper discoidal ; the upper discoidal is giyen off from the subcostal nervure some little 
distance beyond the cell, which character is only found amongst Indian Zyc@nide in the 
genera Gerydus, Paragerydus, Logania, some species of Poritia, Zephyrus and Liphyra; 
the middle disco-cellular nervule springs necessarily therefore from the subcostal nervure, 
is short, straight, upright; the lower disco-cellular is about one-fourth longer than the 
middle disco-cellular, upright, concave ; the second median nervule given off a short distance 
before the lower end of the cell. In the hiadwing the first subcostal nervule is given off 
quite close to the apex of the cell; the disco-cellular nervules are outwardly oblique, 
concave, the upper slightly shorter than the lower; the second median nervule given off 
exactly at the lower end of the cell. The male has no secondary sexual characters. 
The genus Zwuasfa contains buta single species, which is strictly confined to the outer 
ranges of the Western Himalayas. In general appearance it is a “Blue” rather than a 
“ Hair-streak,” the apex of the forewing broadly black on the upperside, both wings with a 
broad discal white band, the rest of the wings blue. The underside is pale brown, 
the white discal band narrower, longer and very clearly defined, some white markings on the 
margin, the hindwing with a black spot in the first median interspace near the margin 
surrounded with a bright orange ring, with a streak of the same colour on the abdominal margin, 
The flight of Z. milicnia, Hewitson, is weak, and I have only found it amongst trees and bushes, 
upon which rather than on the ground it frequently settles, The sexes are alike.
