ish-brown antemarginal spots are reduced. The upper tail long, the point rounded, not sharp as in athamas 
and arji. Forewings with a small round subapical dot and a large, nearly circular spot between the radials. 
Under surface very characteristic, quite different from that of the other athamas forms, in having on the 
hindwing the median band narrower than above and bordered clistally along its entire length from the costa to 
the anal angle by a broad, black undulate line. The brown submarginal lunules accompanying this black borde¬ 
ring line, are much larger than in the allied athamas forms and even arji, being margined distally by most 
conspicuous, unusually broad, black lunules. Also on the under surface the forewings have the submarginal 
lunules more broadly bordered with black proximally than in athamas or arji. Taking it all together, anda- 
manicus is the darkest by far of all athamas forms. Compared with India, Ceylon and the Macromalayan Re¬ 
gion, athamas seems to be very scarce in the Andamans, for Rothschild in his Monography on Oharaxes does 
not mention at all its occurrence there, and Moore just says: “8. Andamans”, without telling from what source 
he had that information, nor even without having any specimens to compare, which was not at all his wont. 
— uraeus R. a. J. A common butterfly of Borneo, also from the Natuna Islands, lacks, like faliscus (134 a), uraeus. 
on the forewings the small anterior subapical dot, but has the median bands on the upper surface larger. Tiie 
early stages were worked out by Dr. Martin in southern Borneo. Larva on Albizzia stipulata Boist., the 8ingon 
tree of the Javanese; of sap-green colour, fullgrown 5 cm in length. Head green, with 4 prongs or horns 
bent backward, the middle, frontal pair of which is twice as long as the lateral pair. The horns are finely ser¬ 
rate, the teeth pointing down and inwards. The very strong mandibles are yellow, with a short, comma- 
shaped black streak to the right and left in the place of the eyes. On either side a whitish festooned lateral 
line, above which white dots indicate the openings of the tracheae. Above the middle segments two streak¬ 
like whitish transverse bands. When pupating, the suspended larva forms almost a complete ring, the head 
touching the anal extremity. Pupa stout, smooth, rounded, green with dull gloss and shaded with white, or 
rather white with green markings; a fine green dorsal line, to the right and left of which two broader green 
lateral stripes; wing-cases more green cost.ally; altogether the front end and venter more green, back and anal 
end more white. The trachaeic openings represented by brownish-yellow dots; cremaster surrounded by 6 
glossy rufous tubercles. After 11 days the pupa appears in the morning discoloured, the white discal band 
of the forewings shining plainly through; but only between 1—2 o’clock in the afternoon the imago appears. 
— faliscus subsp. nov. (134 a) is not so large as uraeus of Borneo, which also influences the width of the me- faliscus. 
dian band, particularly on the under surface. The subapical spot likewise smaller than in uraeus, but some¬ 
times accompanied by a second one, approaching the mainland form. $ not yet known, although the $<$ are 
in the lowlands of northeastern Borneo not at all scarce in wet places or where excrements are exposed. 
The West-Sumatraform is very different from faliscus, approaching in size rather uraeus, but retaining, in 
contradistinction to the Borneo-form, the narrow band on the under surface of the hindwings. — kamie- kannegietcri. 
gieteri Lathy was lately discovered in Nias, and described from 8 specimens in the Adams collection of the 
British Museum. It is distinguished by the conspicuous black stripes on the underside, especially the black 
subanal spot on the forewings being more distinct at the submedian nervure, and the redbrown lunules are absent 
between the median nervules on the hindwings. Very scarce and local, since among ca. 20 000 specimens 
brought to Berlin within 10 years by Prof. Thieme, athamas was not represented. From the western form 
Icannegieteri is easily distinguished by the narrower green median band. If the form of the Malay Peninsula 
can be at all separated from faliscus and uraeus, it would have to receive the name samatha Moore which was samatha. 
created for the Tenasserim form which greatly resembles from Perak and Renong as well as Petjaburi 
(Siam). The small preapical spot on the forewing apparently always present, the median band somewhat 
narrower than in uraeus. A most interesting form, on account of its close approach to the North Indian race 
and the existence of two sharply separated seasonal forms, is the Javanese attalus Fldr., of which the rainy attains. 
season specimens approach uraeus, but with a larger subapical spot on the forewings and the white submar¬ 
ginal spots on the hindwings more prominent. $ somewhat like the figured f. bharata (134a). Common in the 
West of Java up to altitudes of about 3000 ft.; larva figured 1828 by Horsfield. Pupa largely green, with 
white Avingcases and delicate white subclorsal and lateral stripes. — fruhstorferi Rob. (134 a) is the form of fruhstorfer i.
