towards the costa indistinct or suppressed here, the light discal stripes much narrower than the dark vein-

Fruhst., of which only a few HU are known, has rounder wings, very broad white stripes and small yellow anal 
spot. Siam. — xenoclides Fruhst., from Hainan, has narrower light stripes than all the other forms. xenoclides. 
P. Ieucothoe. Differs from P. macareus and P. xenocles chiefly in the shorter and more rounded hind¬ 
wing, which has no yellow anal spot, in the reduction from the basal side of the light patches and the longer 
discal stripes of the hindwing. Even in the lightest specimens the cell-spots of the forewing are not developed 
costally; none of the light stripes of the hindwing nor the posterior stripes of the forewing quite reach the base, 
whilst the discal stripes of the hindwing are very broad and extend close to the submarginal spots; in the darkest 
specimens only the submarginal spots of both wings and the short discal stripes on the hindwing are developed. 
The $ has even less and smaller light markings than the H- Malayan. The butterfly, which is Euploeid- 
like in appearance and flight, flies in the spring and autumn in wooded districts of the plains and hills. — leu- Ieucothoe.

forewing brown, with small submarginal spots, and before the hindmargin a trace of a discal streak; on 
the hindwing, in addition to the submarginal spots, there are 6 brown-shaded grey discal stripes, which are 
more distinct on the underside, moreover the cell bears beneath a small apical spot, which above is only indi¬ 
cated. Malay Peninsula and North-East Sumatra. Some specimens not distinguishable from the next form. 
— interjectus Hour., from South-East and West Sumatra, has no spots in the cell of the forewing, the discal interjectus. 
stripes of the forewing are short, the anterior discal spots usually dot-like, and the cell of the hindwing for 
the most part black-brown. In the $ the discal stripes of the hindwing are somewhat smaller than in the $ 
of Ieucothoe. —- ramaceus Westw. (47 b). A much darkened form. H : the discal stripes of the forewing are ramaceus. 
suppressed, at most there are traces of two spots before the hindmargin. The discal stripes of the hindwing 
are short and always much narrower than in the preceding forms, usually much narrower than the interspaces. 
$ without discal spot on either wing; the submarginal spots small, partly suppressed, beneath somewhat 
larger and here there are also faint discal stripes before the abdominal margin of the hindwing. North and 
South Borneo. 
P. delesserti. Body above black, at the sides of the thorax with greenish grey hairs, head spotted 
with white, underside of the body white, abdomen with black median and lateral lines. H : wings white, 
very slightly greenish, with black vein-stripes which are widened at the distal margin, the white stripes of 
the forewing enclose a submarginal row of black patches, the cell of the forewing for the most part black, with 
white spots and lines; hindwing with yellow anal spot, before which a second spot is usually placed, both spots 
beneath large. The black markings on the under surface smaller than above. The $ larger than the H> the 
black markings reduced, the light parts of the wings transparent, smoky or chalky white, the yellow anal spot 
small. The earlier stages unknown. The butterfly flies in wooded districts in the plains and in the hills and 
occurs all the year round, but is especially common in the spring. Whilst the $$ are only rarely captured, 
the He? are me t with in large numbers on sandy places on the river-banks and at wayside puddles. The $ 
is a strikingly faithful copy of the Danaid Ideopsis daos and the Zygaenid Cyclosia pieridoides. Malay Pen¬

(= laodocus Deh., dehaani Wall., catoris Grose-Smith, labienus Fruhst., sacerdotalis Fruhst.) (47 c). The three 
short white discal streaks near the apex of the cell on the hindwing above are narrower in the H than the black 
vein-stripes between them. Malay Peninsula, Penang, Sumatra, Banka, Java, Borneo, Natuna. — hyalinus hyalinus. 
Fruhst. The costal margin of the forewing beneath somewhat more extended black at the apex in both sexes 
than in the preceding form, and the white submarginal spots on the upperside of the hindwing straighter in 
the H- Nias. — palawanus Stgr. (= palaAvanicus Rothsch.). The three white discal stripes which are placed palawanus. 
near the apex of the cell on the upper surface of the hindwing are broader than in the preceding forms, the 
white cell-patches on the forewing beneath are intersected by black longitudinal lines, which seldom occurs 
in the other forms. Palawan. 
P. megarus. Underside of the abdomen without black median lines. The scent-organ of the H strongly 
developed. The white markings slightly greenish; forewing with 3 rows of greenish white spots between 'cell 
and distal margin, the spots of the two inner rows placed between the 1 st median and the submedian united 
into three stripes, on the other hand the spots placed before the 1 st median nearly always isolated; on the hind¬ 
wing in the basal half some long greenish white stripes, round the apex of the cell several short streaks and 
between these and the distal margin three rows of spots, of which the submarginal ones are lunular. The
