more distinct, whilst the second and third spots of the transverse 
band of the secondaries are not dislocated.

Expanse, ¢ 54, 9 50 millim. 
¢o. Upperside: both wings dull violet; primaries with costa 
blackish, of medium width, and posterior margin rather broader ; 
cell closed by a distinct, black, curved, narrow spot, and nervures 
intersecting the surface with black. Secondaries with broad brown 
costa, rather narrow posterior margin, increasing broadly at the 
anal angle; abdominal fold grey; nervures darkly intersecting 
the surface. Tail longish, black, tipped with white; the closing 
of the cell is slightly darkened. Underside: wings ochreous 
brown, with darker spots encircled with whitish. Primaries with 
three large increasing cell-spots, the third vein very irregular and 
large ; below this is another large spot in the lower median angle, 
above it is a trace of a minute spot on the costa; subdiscal area 
slightly darker, edged very distinctly with whitish, whilst below 
the second cell-spot is a light Y-shaped mark in this area; trans- 
verse band composed of six longish spots, the upper four being 
distinct ovals, a small one near the costa; the second shifted right 
outwards, the third a little further out, but, on account of its 
larger size, its inner margin is shifted inwards also; fourth shifted 
outwards again, fifth and sixth spot below each other ard shifted 
well inwards ; below these is a trace of a small spot below the 
lower median nervule ; submarginal row indefinite and indistinct. 
Secondaries with a fair-sized spot at the basal extremity of the 
costa, and four longish basal spots below each other, the upper 
three being very close together, the fourth shifted right inwards 
and being in line (horizontally) with the third; following these 
are three large spots below each other; cell closed by a large 
irregular spot, below which is a larger spot than usual occupying 
the lower median angle ; transverse band composed of eight spots 
in pairs ; the lower of the first pair is shifted outwards, the second 
pair is shifted right out and detached, the lower of these two being 
further out than the upper; the third pair well inwards, the lower 
of these two being shifted slightly outwards; seventh angular spot 
shifted right inwards and confluent with the eighth spot, which is 
unusually long, extending close up to the fourth basal spot; submar- 
ginal band distinct, sublunar; lobe-spot black, edged above with blue 
metallic scales, a black spot on each side the tail, with superimposed 
blue metallic scales, which are more plentiful on the inner spot. 
2. Upperside : both wings violet ; primaries with broad brown 
costa, broader posterior margin, and very broad apical area; 
secondaries with broad brown margins all round, diminishing 
slightly in the anal area. Underside like the male, but paler and
