posterior margin, two otellate spots of more than tsual size, the exterior one presenting a re- 
gularly orbicular black spot in place of a pupil, and being bounded exteriorly by a narrow 
pale rufous ring, a more saturated narrow rufous arc forming the interior iris ; this is continu~ 
ed in form.of a narrow band in an oblique course through the middle of the adjoining spo 
to the anal appendage, from whence it rises again for a short distance along the extreme angle 
of the wing, being edged exteriorly by a black streak coveted with greenish-silvery irrorations ; 
an obsolete series of three siiccessively paler black lunules, of which the first is covered with 
a silvery crescent, stands exterior to the large ocellus in close contact with the posterior 
margin. ead and dody brown above. Thorax covered with lax white hairs. Addomen with 
‘shorter yellowish hairs underneath. Avenue banded with white and tipt with rufous.” 
(orsfield, 1. 6.) Described from a single specimen. 
“Mate. Differs from Horsfield’s description on the UpPERSIDE of the A‘ndwing in that 
thé cyanéous colour is placed broadly on the outer margin, extending upwards towards the 
middle of the wing between the third median nervule and the subcostal nervure, not as 
stated by Horsfield covering the hindwing ‘excepting the exterior and interior borders,’ 
‘Hewitson’s figure shows the hindwing entirely covered with the blue colour. [In specimens 
from Sikkim the blue colour pervades all the hindwing as desctibed by Horsfield and figured 
by Hewitson, it is only restricted in specimens from the Western Himalayas.] Forewing 
furnished on the underside with a bunch of long black hairs attached to the inner margin 
jear the base and folded beneath. Azzdwing with a corresponding cup-like depression on 
the underside, marked on the upperside by 4 shining bate round patch near the costal base 
of the wing and covered by the forewing. A male from Sikkim differs from specimens taken in 
the Kulu Valley in the grotind-colour of the underside being much Garker and of a cupreous 
purple shade. FEMALE. UppersIDE, doth wings glossy fuliginous, paler on the disc of the 
jorewing. Hindiving witha conspicuous black spot on the margin between the first and second 
median nervules, marked anteriorly with scattered white scales, which also appear decreasingly 
in the two next interspaces beyond and in the one before that containing the black spot, a fine 
marginal white line not reaching the outer angle, then a black line; the c/a white between 
the tail and the discoidal nervule ; the anal lobe with an ochreous and metallic green spot, 
tail black with a white tip. UNDERSIDE, doth wings agreeing in the ground-colour with 
N.-W. Himalayan specimens.” 
“ The single fernale described above was taken at a low elevation in Sikkim in October.” 
(de Nicéville, \. c.) 
Mr. Moore says that specimens from the Kangra Valley are “identical with Javan type.”’ 
In my long series of specimens I find considerable variation : those from the Western Hima. 
layas have the ground-colour of the underside much paler and all the markings less promi- 
nent than those from the Eastern Himalayas ; the size of the black spot on the underside of 
the hindwing near the margin in the first median interspace is very variable, being in some speci- 
mens obsolete, in others very large, broadly surrounded with orange; and there are many 
other minor differences. Vhe black portions of the wings on the upperside are beautifully 
glossed with golden bronze in some lights. S$. zasaka appears to be nowhere common, though 
Mr. A. Grahame Young has obtained several specimens in the Kulu Valley, Mr. Otto MOller 
possesses specimens of both sexes taken in March and June, and the Rev, Walter A. Hamilton 
has sent it to me from Shillong.
