band on the hindwing; the $ exhibits yet the general upper surface shown by the Ticherra, Eooxylides. and 
many other genera; above brownish-black with a white anal area of the hindwing. The under surface, however, 
is entirely characteristic, and here the two sexes agree in the forewing showing dark brown transverse bands 
and the hindwing being dotted dark. nioorei Fruhst. (= sugriva Hsf. p. p.) (158 h) is at once discernible moorei.

surface exhibiting distinct, rather intense bands and spots (which are absent in areca), though with less marking 
than in phorides. — Still farther to the south the species proceeds as isabella Fldr. ($ = jolcus Fldr.) (158 h) isabella. 
as far as Australia, where, however, they only inhabit the north-eastern portion, to the south as far as 
Townsville or Kuranda in Queensland. In this form the marginal blue of the hindwing only extends below 
the apex to little beyond the centre of the margin downwards, but it extends deeper into the wing, as in Indian 
races, so that it almost forms an ellipse; also in the $ the hindwing is white almost as far as below the apex 
and at the hind-margin proximad as far as beyond its centre. Specimens from the Salomons and some inter¬ 
mediary islands differ from the latter in the extent and bordering of the blue resp. white area, as for instance 
the New Guinea form: arfaki B.-Balc. — To the east the species proceeds farther, over Celebes as Bangkai, arfaki.

Palawan form the dark dots of the hindwing beneath are considerably thicker than in isabella, and the white 
anal portion of the upper surface of the $$ is smaller and is more thickly crossed by the veins. The species 
goes on to the Philippines where, however, Semper only mentions it from Mindanao. In these origenes -Fruhst. origenes. 
(= sugriva Smpr. nec Hsf.) the two grey silver streaks at the anal angle of the hindwing are more distinct; 
and the under surface of the wings as well as the tails are lighter brown in phocas, darker brown in origenes. 
— Larva very similar to that of Deudorix ( Virachola) isocrates, but easily discernible by the 7th and 8th segments 
being white, with small purple brown spots on the sides, whereas isocrates has only on the dorsum of these 
segments single small white spots. Pupa exactly like that of isocrates. The imago prefers the blossoms of 
Leea; it favours certain habitats and, for instance, disappeared in a district of India (Karwar) after the place, 
where it was frequently met with before, was cultivated. It has a very agile flight and likes to settle on the 
ends of twigs projecting over the road, though frequently at an altitude of 4 to 5 m, so that it can only be 
captured with nets on long rods; in this way, however, I took dozens of them. The when meeting 
each other, most swiftly fly about in an oscillating way, whizzing to and fro in couples in enormous swings. 
- A form or species of this genus, ines Sivh., from the Andamans, has remained unknown to me. for which 
reason nothing can be said about it, whether it belongs here or not.

Separated already in the exterior by the hemochrome colour above from most of the species of the 
preceding genera; distinguished by the pointed apex of the forewing and by the hindwing terminating in an 
entirely straight tail. Subcostal vein with three branches, whereby it is separated from the following genus 
(which is more externally similar than closely allied.

the hindwing of the $ some small blackish spots form a transverse chain from below the apex to the submedian

Java, whereas in East Java the form singama Fruhst. (157 c as singana) occurs. The latter is said to be smaller singama.

maintainable as a geographical race). Also in Sumatra pita occurs, where it is said also to differ somewhat 
from Javanese.
