NEW NORTH-EASTERN SUMATRA BUTTERFLIES. At 
outwardly beyond the chevron mark rich chrome-yellow, this colour outwardly 
extending into the interspace on either side of the submedian one. Hindwing 
with a broad discal rich deep brown band crossing the middle of the cell, widest 
on the costa, dislocated and slightly shifted outwardly posterior to the cell, 
fading away to nothing in the submedian interspace; a broad outer discal 
irreoular similar band, anteriorly it curves round the large anterior ocellus and 
throws out inwardly a spur placed on the lower disco-cellular nervule, ending 
posteriorly on the submedian nervure ; a submarginal series of six perfect ocelli, 
the anterior one much the largest, the fifth the next largest, the second, fourth 
and sixth the next in size and equal-sized, the third the smallest, the sixth 
bipupiled ; two submarginal limes—the inner one broad and deep red, the outer 
“narrow and deep brown ; cilia pale yellow inwardly defined by a fine dark 
thread. Antennce with the shaft red, the club black with a red tip. 
Described from three male examples obtained in the Battak Mountains. The 
Species was originally described from a female example. It is the most beauti- 
ful species of the genus known to me, and is probably very rare, as out of some 
thousands of Javan butterflies 1 have received, I have not found LZ. darena 
amongst them, 
Subfamily NyMPHALIN ZA.

Description : Mane. UPprrsipe, both wings rich shining purple, all the 
veins more or less narrowly defined with reddish-ochreous. Forewing with the 
usual velvety-black shining sexual patch occupying half the surface, commenc- 
ing on the inner margin ab less than half the length of the margin from the base 
and reaching the anal angle, reaching to the lower discoidal nervule, and extend- 
ing on the disc along the first median nervule and submedian nervure, but never | 
quite touching the discoidal cell; a similar black streak extends broadly along 
both sides of the upper discoidal nervule. Hindwing with a large velvety-black 
shining sexual patch at the apex, ending abruptly at the second subcostal ner- 
vule ; the outer margin rather, and the abdominal margin very, broadly fuscous. 
Cilia of the hindwing reddish-ochreous, of the forewing posteriorly reddish- 
ochreous, anteriorly black. UNDERSIDE, both wings castaneous, crossed by 
numerous more or less zigzag shining pale purple lines. Forewing with a 
round white subapical spot. Aindwing with a discal series of five oval deep 
castaneous spots, one in each interspace from the submedian to the upper sub- 
costal, except the discoidal which lacks a spot, the middle spot the smallest. 
FEMALE. UPPERSIDE, loth wings fuscous. Forewing with the basal area 
extending just beyond the disco-cellular nervules rich shining purple ; a broad 
discal somewhat obscure dark fuscous fascia outwardly touched with the purple
