A LIST OF THE BUTTERFLIES OF BORNEO. 137 
Underside. Dark grey fuscous. Fore-wing: first discal spot 
indistinct, 2nd elongate right across cell, third large. The 
transverse band unbroken but angled at the 4th spot as in 
basiviridis, de Nicéy., the 5th spot being shifted well in, the 
6th slightly out again and the 7th immediately beneath almost 
obsolete and enclosed in a light grey patch which reaches 
from the outer half of inner margin to 1st median nervule. 
A distinct sub-marginal row of spots the upper three of which 
are slightly shifted inwards. MWind-wing: indistinct costal- 
basal spot, regular basal row composed of four well-formed 
spots; median row of three spots, the two first well-defined, 
the third large and irregular; a transverse band of two con- 
fluent spots ‘below the costa, followed by one elongate and 
slightly shifted in closing to the end of cell, this last succeeded 
outwardly by a smaller elongate spot, which is the first of an 
irregular series of confluent spots continuing the band to the 
inner margin: a rough sub-marginal row ending at anal angle 
in bright blue iridescent scales ‘outwardly touched with black. 
Cilia fuscous. : 
FEMALE. Upperside. Purple, heavily margined with dark 
fuscous. ore-wing: the dark costal margin extends along the 
sub-costal nervure, partially closes the cell and stretching 
across the radials and 3rd median nervyule, leaves a broad fus- 
cous apical region and an even margin 4-5 mm. wide from 2nd 
median nervule to inner margin. Hind-w ing: margined as in 
male except that the purple disc (brass-green in male) ex- 
tends rather more towards the hind-margin: tail twice as long 
as in male. Underside. Bronze-fuscous. Markings as in 
male, except that the discal spots of the fore-wing are rather 
heavier.

Messrs. Druce and Bethune-Baker who kindly examined this 
species for me, reported it as unknown to them. ‘The underside 
ds like that of basiviridis, but the totally different upperside of 
the male at once distinguishes it from that species.

Distribution: Burma, Malacea, Sumatra and Java. 
All the Sarawak males before me have the costal basal spot 
in the hind-wing, which is not shown in Bethune-Baker’s 
figure of the species. One specimen has the 5th spot of the 
fore-wing transverse band less shifted in than in the typical 
form, so that the spots form an arched, but continuous, band;
