SATYR INAE 
277 
Forewing with two similar pale ochreous costal spots. Hindwing with larger sub- 
marginal blackish spots ; those of the female with a pale centre. Underside darker 
than in the wet-season brood. Forewing with the cell streak paler bordered, the 
transverse oblique discal line somewhat posteriorly angulated, more defined, and with 
more prominent pale lilacine-white external costal border, the outer pale descending 
costal spot also distinct, and the four subapical superposed ocellate spots larger and 
with blurred lilacine-blue centres. Hindwing with similar basal glossy lilacine-blue 
wavy lines, and marginal lunular line, the submarginal ocelli being of more uniform 
size, especially those of the female, and in both sexes the upper five have entirely 
blurred lilacine-blue centres, the lower duplex ocellus only being perfect. 
Expanse, $ 2f, ? 2f inches. 
Habitat. —E. Himalayas, Sikkim; Assam ; Khasia Hills ; Sylhet. 
The dry-season form of S. Sidonis above described is distinguishable from the 
same form of S. Vaivarta , on the upperside, by its general darker colour, the dusky 
lunular submarginal border on both wings, and somewhat larger spots on the hind- 
wing, On the underside both sexes are also much darker coloured ; the forewing 
having a lilacine anterior border to the discal line, this border being much less 
defined in both sexes, the subapical ocelli are also larger and with blurred lilacine 
centres ; the hindwing has all the ocelli, except the lower duplex one, with large 
blurred lilacine-blue centres. 
Distribution and Habits. —In Sikkim, at from 5000 to 7000 feet elevation, Mr. 
L. de Niceville took it most commonly in roads through forests, in October, and the 
late C£ Mr. Cock took it at Shillong in July 55 (Butt. India, 160). Specimens in the 
late Mr. W. S. Atkinson’s collection were labelled Darjiling and Cherra. According 
to Mr. H. J. Elwes (Tr. Ent. Soc. 1888, 316) this Is ct the commonest species of 
Lethe in Sikkim in the zone of forest from 4000 to 8000 feet, between April and 
November, where it is constantly seen flitting along the forest paths, and settling 
both on the ground and on low vegetation. The female seems much rarer, and 
probably flies but little. Sikkim specimens show the markings of the hind wing 
below of a much more distinct and brilliant violet than those from Mandi in the 
N.-W. Himalayas [wet-season brood of Vaivarta], and are rather smaller and less 
brilliant than those I took in the Khasias.” Specimens of both sexes obtained 
by Mr. Otto Moller in Bhotan, in August, are in Mr. J. H. Leech’s collection. 
Specimens from the Khasia Hills are in the collection of Colonel C. Swinhoe. 
Of the illustrations of this species on our Plate No. 87, figs. 1, la, represent 
the male of the wet-season brood, and figs, 1, b, c, the male and female of the dry. 
season brood.
