any case it applies to insects distinct from those shewn in his figure 9, which I here retain 
as metallica; and if hereafter his figs. 7 and 8 are proved to denote a distinct species, it will 
need to be renamed. 
I possess seventeen males and five females of Z. metallica taken in the Chandra Valley, 
Lahoul, at 10,309, 10,400, ¥0,500, 11,000, and 1 1,300 feet at different dates in July and 
August by Mr. A. Grahame Young ; and at Sakti village, south side of the Chang La, Ladak, 
13,000 feet, in July, by Mr. R. D. Oldham. JZ. metallica may be known from L. galathea, Blan- 
chard, and L. omfphissa, Moore, by its uniformly smaller size ; the male on the upperside having 
the blue coloration of adifferent shade, being bluish-green, the forewing with the blue area sharp- 
ly defined, leaving the outer third of the wing black, the veins crossing the blue area also black.

DEscrIPTION : ‘* Allied to P. [=Z.] galathea, Blanchard. MALE. UPPERSIDE, oth wings 
very dark purple, the base only suffused with blue. UNDERSIDE, forewing pale greyish fawn- 
colour, disc suffused with fuliginous, a prominent disco-cellular white-bordered black streak 
and transverse discal row of six spots. Aindwing metallic golden green, a distinct white disco- 
cellular spot, and angular discal series of white spots). FEMALE. UPPERSIDE, both wings 
glossy vinous purple, with indistinct dull orange marginal spots. Cz/ia white, with brown inner 
line.” Otherwise asin the male. (Joore, |. c.) 
This is a very distinct species, and separable at a glance from Z. galathea ; in the male the 
blue of the upperside is of a much deeper shade and restricted to the base of the wing. The 
markings of the underside do not differ. The female may be known by the marginal orange 
spots of the upperside being obsolete, instead of large and prominent. It is very near to 
L. metallica, Felder ; the males can be distinguished by their larger size, the more restricted 
blue area of the upperside, and the purplish tinge of the blue, which is greenish in Z. metallica. 
The females of the two species are exactly alike. I took numerous specimens in the Dras 
Valley, Ladak, in June, 1879 and 1887. 
The sixth group contains but a single species in India, which, according to Mr. Butler, 
belongs to the genus Scolitantides, Hiibner, all the species of which ‘‘ have a peculiar type of 
coloration, the fringe of the wings being alternated with black and white, and the spots of the 
under surface large and black.’* Dr. Lang gives three species of this group as occurring in 
Europe, Z. davius, Eversmann, which is found in South Russia, Asia Minor, and Syria ; 
7. orion, Pallas, which occurs in Central and Southern Europe, Asia Minor, Armenia, South 
Siberia, and Amurland, and is a larger and much darker species than the third species, Z. hylas, 
Wiener Verzeichniss, which occurs in Central and South-Eastern Europe, and Western Asia, 
mcluding Kashmir and Ladak. On the upperside the male is greyish-blue ; on the underside 
white, the black spots very prominent, and the two marginal series on the hindwing enclosing a 
series of orange lunules. The female is smoky-black on the upperside, the base of the wings 
irrorated with purplish scales, and with a distinct disco-cellular black spot on the forewing, and 
indistinct marginal lunules on the hindwing, sometimes with the orange band below showing 
through obscurely ; the underside is like the male. The prominence of the black-spotting 
of the cilia is a marked characteristic of this group, and is only found slightly in Z. medon, 
Hufnagel, and Z. devanica, Moore, of the first and second groups.

+ Dr. Lang in his “‘ Butterflies of Europe” calls this species by Bergstrasser's name dazon, but I follow 
Mr. Kirby in giving precedence to the name Ay/as of the Wiener Verzeichniss. Dr. Lang uses the name hydas 
of Esper (not the Aydas of the Wiener Verzeichniss) for the species generally known as dorydas, Wiener 
Verzeichniss and Hiibner,
