butterfly throughout Celebes in suitable localities, occurring both in low country and in the hills. Fore¬ 
wing long, above rarely with slight indications of vein-stripes, these stripes sometimes very distinct beneath; 
hindwing always with a large, long gold spot before the subcostal, which distally extends to the costa, the 
black marginal band broader than in the following subspecies and less deeply incised. $: forewing beneath 
with a broad white stripe at the submedian even when the wing has no other stripes; cell-spot of the hind¬ 
wing obliquely truncate, anteriorly extending to the point of origin of the subcostal vein or even shorter; 
marginal band as in the 3 comparatively broad at the veins; two principal forms: $-f. lygaea form, nov., 
forewing above without distinct vein-stripes; $-f. lucinda form, nov., forewing above and beneath with grey- 
white vein-stripes and the apex of the cell of the same colour. Peepers says that the insect also occurs on 
Saleyer, which probably rests on a confusion with thestius Stgr. — propinquus Rothsch. (14 a). Abdomen above 
as dark as in hephaestus. 3 : forewing beneath with distinct or faint vein-streaks ; gold spot long, reaching 
the costa distally, 4 black discal spots, the last so united with the marginal and abdominal band that no yelloAV 
submarginal spot is left, distal part of the gold spot placed below the cell about 1 ls as long as the proximal 
part. the vein stripes of the forewing and the apex of the cell grey-white also above; hindwing with gold 
discal spot before the subcostal, the black marginal band more deeply incised than in helena; only the white- 
striped form known. Sumbawa, apparently very rare; the varions collectors who have been on the island 
(Doherty, Everett, Fruhstorfer, etc.) have only captured very few specimens. — sagittatus Fruhst. The 3 
not constantly different from j^'opinquus; forewing rarely with vein-stripes, but these sometimes very distinct; 
the gold spot placed before the subcostal of the hindwing mostly narrow, sometimes very small, rarely absent, 
but sometimes as large as in propinquus, the yellow streak-spot placed below the cell longer than in that sub¬ 
species; most specimens with 2 black discal spots, often only the anal one present, sometimes 3 or 4, always 
a submarginal gold spot at the anal angle. §: hindwing without discal gold spot before the subcostal, commonly 
also the gold spot placed below this vein much reduced; the black discal spots always large, not very variable, 
at least the posterior ones united with the marginal band; two forms: $-f. sciara form, nov., forewing above 
without distinct vein-stripes, and $-f. nympha form, nov., forewing also above with strong vein-stripes and 
grey-white apex to the cell, the extent of the white in the cell variable. Lombok, rather common. — nereides 
Fruhst. <3 very similar to that of the Javan form; hindwing with a row of black discal spots. In the $ 
the cell and disc more extended grey-white. Bawean. — antileuca Rothsch. Abdomen above as dark as in 
sagittatus, not so distinctly lighter in the middle as in helena from Java. <$: forewing above and beneath 
entirely without vein-stripes; hindwing similar to that of helena, without discal gold spot before the subcostal. 
$ above without vein-stripes and with the apex of the cell not margined with grey, beneath with quite indis¬ 
tinct traces of vein-stripes; hindwing with a discal and a submarginal gold spot before the 1. radial, both 
very small, the gold spot placed below the cell almost reaches the base; the black discal spots moderately 
large, the last 3 united with the marginal band, the cell-spot cut off in the prolongation ef the 1. radial. A 
pair from the Ivangean Islands (Prillwitz), in the Tring Museum. — helena L. (= astenous F., heliacon F., 
nymphalides Swains.) (11 c). 3'■ forewing also above at least with traces of vein-stripes, these beneath mostly 
broad, sometimes reduced to faint submarginal patches, the upper ones often reaching the cell; the apex of 
the cell commonly grey-white, no white or yellowish streak behind the cell between the 2. median and the 
base; hindwing usually without gold spot before the subcostal, sometimes with one or two small spots or 
with a long narrow streak before that vein; on the disc 0—5 black spots. $: forewing above always at least 
with faint submarginal vein-stripes, these beneath always distinct and in the middle between cell and distal 
margin broader than the brown-black interspaces, the stripes placed at the 2. median vein not extending to 
the cell, usually also the preceding pair shortened; no stripe behind the cell between the 2. median and the 
base, sometimes the distal half of the wing almost entirely white-grey; the cell-spot of the hindwing very 
variable, sometimes only occupying [U of the cell; no yellow discal spot before the subcostal; the black discal 
spots very variable, often large and joined together, and just as often small, but very rarely quite absent; 
we differentiate 2 forms: §-f. penetia form, nov., forewing above without grey-white apex to the cell and without 
distinct, long grey-white vein-stripes and $-f. pompeus Cr., forewing also above with grey-white apex to the 
cell and grey-white vein-stripes; these cell-patches mostly longer than broad and produced anteriorly 
towards the base, not M-shaped. The specimens of both sexes in which the black discal spots are wanting 
on the hindwing are ab. Jupiter Oberth., whilst those with yellowish red hindwing are ab. rutilans Oberth. 
(= holzi Pagenst.). In ab. pluto Fldr. the yellow area of the hindwing is likewise yellowish red anteriorly, 
the vein-stripes of the forewing are indistinct above, but beneath as broad as in Javan specimens; the spe¬ 
cimen (§) is without indication of locality and probably does not come from Java, as it has on the under 
surface of the forewing behind the cell basally from the 2. median a strong white streak, which is commonly 
found in 3 and $ from localities further west, but never seems to occur in Javan specimens. Java and South- 
West Sumatra. — nereis Doll. 3 '• forewing above with distinct vein-stripes, which on the under surface 
are narrower than in helena; hindwing before the subcostal with long gold spot, which does not reach the 
costa; sometimes a complete row of black discal spots. $: apical third of the cell of the forewing and the 
sharply defined vein-stripes almost pure white, the stripes placed at the 2. median not reaching the cell; 
hindwing above pale yellow, beneath cream-coloured, the black discal spots large, joined together. Engano.
