Tuaco.—Male. Upperside. Forewing dark, velvety ; purpurescent blackish- 
brown, in fresh specimens somewhat tinged with blue, and the edge of the outer 
margin with purple; in older specimens the ground-colour is generally more or less 
dark chestnut-brown; some blue irrorated-strige along the costal margin, and an 
excurved subapical series of small violet-blue irrorated spots disposed between the 
veinlets, the spots elongated near the apex, those below rounded ; between the basal 
interspace of the median and submedian vein is an inconspicuous rounded impressed 
black glandular patch, which is clothed with short broad many-pointed tipt black 
scales, and with some longer narrower tridentate-tipt scales. Hindwing somewhat 
paler, purpurescent blackish-brown, or chestnut-brown, the outer border being broadly 
suffused chestnut-red, fading to dull dark ferruginous, which is sometimes traversed 
by a submarginal series of very small more-or-less pale red or white spots ; the veins 
across the red band also sometimes being black lined; within the upper base of 
the cell is an elongated glandular patch, which is clothed with very densely-packed 
laxly-raised scales, which are of equal width throughout and have obtuse rounded 
tip and base, and with numerous short fusiform slender blackish scales (androconia) 
with an acute point at each end, the patch being also overlapped from its 
posterior edge by a tuft of long blackish hairs. Ciha alternately edged with white. 
Underside deep chestnut-red, with numerous wavy transverse lilacine-cinereous 
strige of more-or-less intensity, these strige being sparsely-disposed on the basal 
two-thirds, and are generally densely-packed and confluent on the outer border, 
where their density forms a more-or-less defined paler nebulous border, the division 
generally being indicated by the angulated curved edge of the dark basal area. On 
the forewing is a prominent triangular costal patch before the apex, which is 
densely covered with lilacine cinereous strige, and on the middle of the discocellular 
veinlet is a minute whitish speckled-spot ; on the hindwing, also, there is a more or 
less prominent subcostal white spot above end of the cell, and occasionally a sub- 
marginal series of white points are more or less apparent. Body beneath, legs, and 
palpi paler brown ; legs beneath cinereous-brown ; antennz brown with a pale tip. 
Female. Upperside coloured and marked somewhat after the style of Salatura 
Genutia. Forewing with the costal border from the base, the outer half, and below 
the submedian vein blackish-brown, the medial area from the lower base of the cell 
being ochreous ; along the base of the costa are some violescent-white strige, and 
before the apex a broad violescent-white subapical band intersected by the dark 
veins, below which are three submarginal decreasing white rounded spots. Hind- 
wing with the costal border and outer margin broadly dark brown, the latter
