1896, ] MR. H. H. DRUCE ON BORNEAN LYCENIDH. 661 
ARHOPALA DRUCEI, sp. n., Bethune-Baker. (Plate XXX. figs. 
1,22.) 
Kinu Balu. 
Expanse, ¢ 55, 2 50 millim. 
3. Upperside: both wings purple, quite dull or somewhat 
bright according to light; costa and outer margin of primaries 
narrowly brown ; costa of secondaries broadly, outer margin nar- 
rowly, brown; tail long, tipped with white, lobe fairly distinct, 
abdominal margin grey. Underside: both wings ochreous brown, 
with darker spots palely margined, those before the transverse 
lines being the darkest. Primaries with three good-sized increasing 
cell-spots, above and below the third is another spot ; subdiscoidal 
area dark, with an indefinite pale lunular mark in the upper part 
at the centre ; transverse catenulated band composed of six con- 
fluent spots, below which is a double spot like the figure 8; the 
upper four spots are slightly curved outwards, the fifth and sixth 
have their inner margins shifted well inwards, but the outer 
margins very slightly so, and these two spots have an outward 
inclination ; submarginal row indefinite but fairly distinct; sub- 
median area paler. Secondaries with a small spot at the basal 
upper extremity ; four basal spots below each other, second shifted 
slightly inwards, fourth well inwards outside the internal nervure ; 
beyond these are three larger spots below each other; cell closed 
by a long subquadrate spot, below which is a small spot in the 
lower median angle; transverse band beginning below the upper 
discoidal nervule, composed of six laterally-edged spots, the second 
shifted outwards, third inwards, fourth inclined outwards, fifth 
angular spot right inwards; sixth long spot very irregular in shape, 
slightly outwards, but extending up to the internal nervure ; just 
above and between the uppermost spot of this series and that 
closing the cell are two confluent spots occupying ,the interspaces 
between the costal, subcostal, and upper discoidal nervures, the 
lower of which is the longer of the two; submarginal row inde- 
finite but fairly distinct ; anal area occupied by bluish meiallic 
scales over a blackish patch ; tail brown, tipped with white; lobe- 
spot velvety black, edged above with metallic blue. 
Q. Upperside: both wings bluish purple, not nearly so deep as 
in the male, with broad margins all round, the apical area being 
the broadest. Underside: both wings rather darker than in the 
male; in the primaries the transverse band has no 8-shaped double 
spot, but ceases on the lower median nervule. In the secondaries 
the transverse band just touches the lower of the two spots on the 
costa, and the three upper spots of the transversal series are 
nearly (not absolutely) confluent, whilst the fifth and sixth are 
confluent. 
In spite of these little differences, the two insects look so pre- 
cisely similar in general pattern and tone that I do not doubt their 
being sexes of the same species, which will come next to A. adatha, 
Hew. ‘There are a male and two females before me, all taken on 
Kina Balu, and kindly lent to us by Dr. Staudinger.
