the radial nervure two vitte united at the base, the upper one 
followed by a round spot; above these between the nervules five 
vittee, of which the one nearest the costa is pointed, the others 
bifid externally, each vitta followed by three spots, of which the 
lower are somewhat lunulate, the upper ones more rounded ; four 
rounded spots near the apex, two near the anal angle. The imner 
margin is glaucous, the apex tinged with brown. Posterior wings 
castaneous, darker in the females than in the males, with seven 
whitish subdiaphanous vittz placed between the nervules, all, ex- 
cept the innermost, followed by a round white dot, beyond which 
the ground-colour of the wings is slightly darker; towards the 
outer margin a series of indistinct whitish spots, sometimes nearly 
obsolete. Cilia of all the wings spotted with white. Below, the 
anterior wings are black with strong blue reflections, the apex 
broadly chestnut, slightly bronzed towards the disc ; the markings 
as above but clearer, with two additional spots on the costa near 
the base. Posterior wings paler than above, the white portions 
more or less irrorated with chestnut scales; on the margin a di- 
stinct series of whitish lunules. 
Head, thorax and abdomen black, clothed with gray hairs ; 
head above and thorax below spotted with white ; abdomen below 
gray ; palpi black, spotted with white ; antenne black.

This species, which much resembles Pap. Agestor and Danais 
Tytia, has the cells of all the wings open. The genus Diadema 
as it now stands requires subdivision ; the neuration I believe will 
be of great service for this purpose.

Anterior wings fuscous with whitish markings, viz. an elon- 
gate spot at the base and extremity of the discoidal cell, an oval 
one near the costa towards the middle, a series of vittee between 
the nervules, of which the first and third from the costa are short 
and narrow, the second also slender but longer, the fourth long, 
the fifth and sixth progressively shorter, well-defined towards the 
base, less so externally, the seventh broad, short, the eighth broad, 
longer than the seventh, the ninth long, commencing near the 
base, the tenth occupying the mner margin from the base nearly 
to the anal angle ; near the margin between the nervules a series of 
seven more or less rounded spots, of which the one nearest the anal 
angle is geminate ; this series, preceded by another of six spots, 
of which all except the first are connected with the vittee by im- 
distinct prolongations. Posterior wings with the base and abdo- 
minal margin whitish, the nervures broadly brown, a broad yitta
