row of hastate markings, inside which, a little beyond the middle, is a row of lunular markings; the usual 
spots and markings towards the base. 
Expanse of wings 2^ inches. 
Nearest to T. svpercilia, Butler. 
12. Tenaris occulta. 
This species is near T. horsfieldii , Swainson, but differs from it in the following respects :— 
Male .— Upper side. The anal third of the posterior wings is wholly pale brownish white, instead of 
being margined with the same colour as the rest of the wings, the basal area being darker than in 
T. horsfieldii. 
Underside. The outer half of the posterior wings, in which the ocelli are situated, is pale brownish 
white, except a space near the apex, which is irrorated with dusky brown ; the rest of the posterior wings 
is dark brown, the outer edge of which colour does not extend to the ocelli, but forms two distinct curves 
partially round them, leaving on the inner side of the upper ocellus a narrow, and of the lower ocellus a 
broader area of the same colour as the outer portion of the wings. 
Female .— Upper side paler than in the male, and the lower ocellus on the posterior wings is entirely 
surrounded by the brownish-white colour of the anal area. 
Underside. The outer two thirds of the posterior wings is pale brownish white, the basal third dusky 
brown, which colour does not extend as far towards the ocelli as it extends in the male. The posterior 
wings are narrower than in the male. 
Expanse of wings, S 31, $ 2£ inches. 
13. Elymnias IvONGA. 
Male .— Upper side. Both wings dull bluish slate-colour, changing to dull brown on the margins; 
outer margins emarginate. 
Underside. Both wings dull brown, darker towards the base and mottled with brownish-grey markings. 
Anterior wings with several light grey markings on the costal margin towards the apex and an indistinct 
light grey area from the apex to near the middle. Posterior wings with a rather small white spot a little 
below the costal margin near the middle, halfway between which and the base is an indistinct rufous 
patch, the apex slightly rufous. 
Expanse of wings 2f inches. 
Near to E. penanga, Hewitson, and E. sumatrana, Wallace ; but, besides other differences, the apex 
of the anterior wings is less acute ; it has a subcostal white spot on the underside of the posterior wings 
which is absent in those species, and the outer margins are emarginate. 
14. SlTHON TEUNGA. 
Male .— Upperside. Anterior wings dull brown, with the inner margin projecting; around, depressed, 
sericeous spot above the submedian nervure about the middle. Posterior wings : anal third white, the 
veins across the white area black, rather broadly tipped with black on the margin ; the upper half smooth, 
devoid of scales ; two tails, that nearest the anal angle the longest. 
Underside. Both wings dull pale brown, darker towards the apex and almost white at the anal angle; 
the inner marginal third of the anterior wings smooth, 'with a tuft of pale brown hairs. Posterior wings: 
outer margin narrowly black, a black round spot at the anal angle, another and two black bars in a row 
above it, and inside these is another row of three sinuate black elongated spots. 
Expanse of wings inch. 
Somewhat resembles S. amrita , Feld., on the underside. 
15. SlTHON KIANA. 
Male. — Upperside. Anterior wings dark brown. Posterior wings : basal and costal third dark 
brown, the remaining part light blue, shading to white towards the anal angle, at which there is a black
