444 LYCENIDA. LEHERA. 
apices of the cell and of the wing, and is rather short, not nearly reaching the apex of the wing, 
the middle disco-cellular nervule originates from the upper discoidal quite close to its origin, 
and is about one-third shorter than the lower disco-cellular, both are slightly concave and upright, 
the second median nervule arises some little distance before the lower end of the cell. In the hind- 
wing the disco-cellular nervules are concave, of equal length, and together form a very obtuse 
angle, the second median nervule originating immediately before the lower end of the cell, the 
internal nervure strongly recurved, tail moderately long, very slightly ciliated. Male without 
secondary sexual characters. In the female the wings are broader, the forewing has the outer 
margin regularly convex, the hindwing has the tail fully four times as long as in the male and 
very fluffy, being heavily ciliated on both edges. The eyes are hairy. The neuration of Lehera 
is very much as in typical Deudorix, Hewitson, but the very different facies, and the length of the 
tail in the female are sufficient to keep Zefera distinct. 
The genus contains but two known species, one of which is represented by a unique 
example. The male of Z. evyx, Linnzus, is brilliantly glossed with rich dark purplish-blue on 
the upperside, the anal lobe is green, as is also the underside throughout except an inconspicuous 
discal series of white spots, the anal lobe of the hindwing is black, the tail black tipped with 
white. The female is very much larger than the male, the upperside shining fuscous, the hind- 
wing with the outer anal third pure white enclosing some marginal black spots between the veins, 
the cilia and tail entirely white, the latter very long. Z. skinneri, Wood-Mason and de 
Nicéville, differs only in having all the green coloration replaced by clear ochreous. It occurs in 
Cachar, while Z. eryx is found in Sikkim, Assam, Burma, and has been recorded from China.

DESCRIPTION: MALE. UPPERSIDE, both wings black. Forewing with the basal two- 
thirds glossed with rich steely purplish-blue, gradually merging into the black ground- 
colour, not sharply-limited. Ci/za black. Aimdwing almost entirely glossed with the same 
shade of purple, the costal and abdominal margins alone free, the latter somewhat pale fus- 
cous, and thickly clothed with long fur-like modified scales; the anal lobe emerald green, 
extending narrowly up the abdominal margin; the /az/ black tipped with white. Cilia 
cinereous. UNDERSIDE, doth wings uniformly emerald green. Forewing with the inner 
margin paler, a very indistinct greenish-white somewhat macular discal band not reaching 
the costa. Hindwing with a macular whitish irregular discal band, the anal lobe centred 
with deep black, two indistinct submarginal irrorated black spots beyond, a whitish anteciliary 
fine line towards the analangle. FEMALE. UPPERSIDE, doth wings shining fuscous. Hind- 
wing with the outer anal third of the wing from the abdominal margin decreasingly to the 
discoidal interspace pure white, its inner edge very irregular, the black area extending into 
the white portion anteriorly and marginally as far as the second median nervule, posterior to 
which are two large oval black spots, the large anal lobe centred with green, the ¢az/ long, pure 
white and strongly ciliated, the abdominal margin pale fuscous. C7/ia long, pure white, becom: 
ing fuscous towards the apex of the wing. UNDERSIDE, doth wings greenas in the male.
