colour; a submarginal narrow waved similar fascia, the outer margin, especially 
at the apex, broadly dark fuscous. Hindewing with the base and a large discal 
area rich shining purple, the latter area inwardly bounded by the false termina- 
tion to the discoidal cell, anteriorly by the second subcostal nervule, posteriorly 
by the first median nervule, outwardly not reaching the margin ; a waved, 
rather broad, submarginal line. UNDERSIDE, both wings asin the male, but 
the ground-colour and the shining pale purple lines all paler. 
Nearest to 7’. robertsia, Butler, from the Malay Peninsula, from which it 
differs conspicuously in both sexes in lacking the two white (sometimes tinted 
with ochreous) spots on the upperside of the hindwing near the outer margin in 
the upper median and discoidal interspaces ; and on the underside of the hind- 
wing in having the marginal narrow slightly waved line, and the submarginal 
highly waved broad line, pale purple throughout, in 7’. robertsia they are white. 
Mr, A. RB. Wallace describes a “‘ Local form £&.” of T. robertsia from 
Sumatra* thus :—“ Browner [than 7’. robertsia], with the blue portions more 
violet, and the white posterior spots replaced by rufous.” In 7’. feos these spots 
are barely traceable. “The [lower] disco-cellular [nervule of the forewing | 
meets the median nervure at the origin of the second median nervule.” In the 
four specimens of 7’. feos and eight of 7’. rebertsia before me as I write, I find 
that the lower disco-cellular nervule of the forewing, though varying a hundred 
per cent. in position, always meets the median nervure well before the origin of 
the second median nervule, which agrees with Mr. Wallace’s remarks on the 
neuration of the latter species, and would appear to separate his Local form JA. 
and my 7’, teos from it. It is interesting to note that 7. atlita, Fabricius, and 
T’, teos, de Nicéville, differ precisely in the same way, 7.¢., in the absence of the 
white spots on the upperside of the hindwing, these spots being present in their 
Malay Peninsula correlatives, T. teuthras, HiGwiteon and 7’, robertsia, Butler. 
Described from three male specimens in my own and one female in the collec- 
tion of Dr. L. Martin.

Description: Mare. UpprrsipE, both wings black. Forewing with the 
following milky-white markings :—a very narrow streak in the discoidal cell 
extending beyond it but for a very short distance; three narrow subapical spots, 
the middle one the largest ; a large oval spot in the first median interspace, a 
quadrate one below it filling the interspace and indented at both sides, a small 
elongated spot on the sutural area, these three spots outwardly marked with 
pale blue; a discontinuous submarginal whitish line, broken in the upper
