296 LYCAENIDA. THECLA. 
The sixth division that I have made in the Indian Lycanide I have called the 7hec/a group, 
and it contains eighteen genera, which may be divided into two subgroups: the first contain- 
ing six genera, which, asa rule, possess one short tail to the hindwing from the termination of 
the first median nervule, though there are some exceptions, the tail being sometimes absent : 
the second containing twelve genera, which all possess two short tails (under half an inch in 
{ength) to the hindwing in both sexes, though one aberrant genus, Zes¢us, Hiibner, has three 
tails in the female. In all these genera the tails arise from the terminations of the submedian 
nervure and first median nervule, except in A/o¢a, mihi, in which they arise from the termina- 
tions of the first and second median nervules. The genus 7hama/a is also aberrant, but in 
another way, the outer tail from the termination of the first median nervule being much longer 
in the female than in the male ; the inner tail is also a little longer in the female. 
The first genus of the first subgroup, Zec/a, Fabricius, as restricted in this work, is, I 
believe, purely palzearctic, one species only being found on our north-western frontier. It isa 
very plain-looking insect, upperside glossy purplish-fuliginous, the underside dull brown, with 
a prominent discal white line. The males are furnished witha small oblong patch of differently- 
formed scales at the upper outer end of the cell of the forewing on the upperside, which are want- 
ing in the females, the neuration at this point differing in the opposite sexes. Both sexes have 
only two subcostal nervules to the forewing, all the other genera of the subgroup having three. 
The next genus, Zephyrus, Dalman, is probably also purely palzarctic. Two species occur 
in Europe, many others are found in the northern half of Asia from the shores of the Black 
Sea to Japan. In India it is only found in the Himalayas and in the hilly portions of Assam ; 
thirteen species are included in this work. There is much diversity in the coloration and markings 
of these species, many of them are brilliant metallic green on the upperside in the males, others 
are duller green in some lights, violet in other lights, others are brown with some ochreous 
markings on the forewing. Some species are brilliant silvery or satiny-white on the underside, 
as in the genera Curetis, Hiibner, and Driva, mihi, One Indian species entirely lacks 
tails, usually however the species are tailed. 
The next genus, Zuasfa, Moore, shares with the genera Gerydus, Boisduval, Paragerydus, 
Distant, Zogania, Distant, some species of oritia, Moore, Zephyrus, Dalman, and Liphyra, 
Westwood, the peculiarity of the upper discoidal nervule of the forewing being emitted from 
the subcostal nervure some little distance beyond the apex of the discoidal cell, instead of 
at a greater or less distance before the apex of the cell as usual, The genus contain but a 
single species, which is strictly confined to the outer ranges of the Western Himalayas. On 
the upperside it is blue, the apical third of the forewing black, the disc of both wings bearing 
a broad white band. 
The genus Chetoprocta, mihi, has been proposed in this work for the reception of a single 
‘*hair-streak ” which has the end of the abdomen inthe female thickly coated with hairs, 
with which the eggs of the butterfly are thickly covered after being laid on the branches of 
narrowly, the internal region darker. UNpeErsipr, both wings white, scarcely glossy, dotted with black, 
with an exterior undulate striga interruptedly broken and dots within the margin black, an evanescent 
striga placed between.” ; : A ahd ee . 
“« Smaller than the preceding species [C. madlayzca, Felder), and differs distinctly from it in being broader 
throughout the length of the costa, in having the terminal margin of the forewing much narrower and 
bulging out into a bow, in the absence of a little tooth on the disco-cellular nervule of the forewirg, in 
having the border of the hindwing generally narrower though broadening out at the costa, and also in having 
shorter inner margins to both wings.” (/edder, |. c.) 1 j ; 
“FemMaALe. Upprrsipe, Goth wings dark chocolate brown. Forewing with a large discal streak, occupying 
near'y all the lower half of the cell, and deflected and covering more than half of the median nervules, orange- 
yellow. Hindwing with a discal patch, which is much waved and sinuated, and extends from near the apex to the 
third median nervule, orange-yellow. UNDERSIDE, doth wings pearly grey, with a small fuscous streak near the 
ends of the discoidal cells, a waved fuscous linear fascia a little beyond the middle, followed by a wider and more 
obscure fascia, and a submarginal series of dark fuscous linear spots. Body both above and beneath more or 
less concolorous with the wings. /a//z pearly grey, with their upper surface and apex fuscous. Legs 
pearly grey, more or less annulated with fuscous. MaALr. A specimen of this sex in the Briti»h Museum 
resembles the female, but has the pale discal markings on the uppERsIDE of doth wings more reddish in hue, 
and the discal patch on the Aindwing larger in size.”’ 4 ; : : 
“J have only received a singe fema'e specimen of this apparently somewhat rare spec’es. It is peculiar 
by the similarity of the sexes, the usual fema'e characters of colour and markings being, in this species, also 
transferred to the other sex.” (Distant, }. c.) Ay. 
I have not seen this species, so can offer no remarks regarding it,
