blunt extremity of the head of the pupa is brown and crusty over eyes and palpi, and behind each sheath 
of the antennae we notice a small, pointed brown wart. Around the end of the anus, the cremaster, there 
are, like in athamas, six brownish-yellow, glandular protuberances. The pupa] stage lasts 13 days and 
the imago appeared between 9 and 10 in the forenoon, after the pupa had turned dark in the evening 
before and the discal white band of the forewings had been shining through in the morning. The food- 
plant was Nephelium lappaceum L., but the large •species yielding finer fruit which the Javanese call 
,,Rambutan Atjeh“ (Dr. Martin). The butterfly occurs from the coast up to an elevation of about 1200 m. 
It flies swiftly and does not fear even the proximity of human beings, for I saw it flying in large gardens near 
Sukabumi and both Dr. Hagen and Doherty have come across it in the streets of Singapore and Tungo. It 
is also frequently stated that single wings were found from which we may conclude that schreiber is very much 
pursued by birds. The butterfly, however, is everywhere extremely rare except in Java, of some races even 
only the one sex is known. Range: Macromalayana, to the north as far as Assam, observed by myself in Siam 
and Tonkin, one race mentioned also from the North Philippines. It is presumably found yet in Palawan and 
in other islands of the South and Central Philippines. — wardi Moore is considered one of the most beautiful wardi. 
and rarest day-butterflies of South India. Upper surface extensively bordered in ochreous also in the <$, cell 
of the forewing with two elongated maculae instead of a white spot as in insular races. The white median band 
on both the wings peripherically richly bordered in light blue. The butterfly is fond of fluttering round iso¬ 
lated trees on rocky ledges of rocks during the hottest hours of the day. Larva on Wagartea spicata the thorns 
of which make it rather dangerous to hunt for the larva. As in all the large species, the development 
from the larva into a pupa takes a long time, and a larva which had crept out on the 25th of October, 
pupated only on January 26th. Larva dark green with a yellow lateral stripe. Horns rust-brown as well as 
the sides of the head. — assamensis R. and J. White median band of the forewings brought nearer to the assamensis.

margined by ochreous. Very rare, only few and one $ known from the Naga and Khasia Hills. — tisamenus tisamenus. 
subsp. nov. approaches schreiber vom Java (135 a). The however, are considerably larger than the 
of the other insular vicarious types. The small white subapical spots of the forewings either absent, or to be 
noticed only as minute clots. White median band of the hindwings distinctly broader than in Borneo-^^. 
Type from the Malayan Peninsula or from Singapore, in the Museum of which I also found it among the stock 
of duplicates. In the Tring Museum there are from Penang and Perak. Maybe also specimens from Birma 
and the Riouw Archipelago belong to tisamenus and presumably also the specimens I observed near Muok-Lek 
in Central Siam, as well as a specimen which was taken near Chiem-Hoa (Tonkin) in August and which is now 
in the Tring Museum. — entheatus subsp. nov. is known to me from a $ in the collection of the British Mu- entheatus.

of the upper surface of the hindwings, an entirely paler total colouring and beneath more considerable brown 
spots. Billiton, in a nearly allied form also in Banka. — valesius subsp. nov., undoubtedly one of the rarest yatesius. 
day butterflies of Sumatra, lies before me from Padang-Pandjang, the west of the island. $ smaller than the 
$$ of the Malayan Peninsula; like in schreiber schreiber, with a very large white subapical spot and a supple¬ 
mentary macula in the cell of the forewing. Discal stripes of both wings broader than in tisamenus. The bor¬ 
dering of the band on the hinclwing lighter blue and more extensive than in tisamenus and malayicus. In spite 
of having collected in North East Sumatra for 13 years, Dr. Martin did not find it, but Dr. Hagen got in 
about the same period, a $ from the Gaju-Districts from natives in January 1892, as well as two from the 
Island of Banka. $ according to the material of the British Museum larger than the £ of tisamenus from Singa¬ 
pore with more extensive white bands. — niasicus Btlr., according to the $ lying before me and being hitherto niasicus. 
not yet described, differs from the $ of schreiber from Java by the more undulated white band of the forewings, 
a somewhat narrower median stripe of the hindwings exhibiting at the same time more pronounced white sub¬ 
marginal lunae. The subbasal band of the under surface much broader than in Javanese of a greyish-green 
colouring and bordered more intensely black; Island of Nias, very rare. — schreiber Godt., the name-type, is schreiber. 
of the smallest habitus. The small preapical spots of the forewings are always distinct. Median band more 
strangulated than in the allied forms, but sharply defined and bordered either by light-blue or violet. $ with 
indistinct, $ with distinct reddish-brown terminal band of the hindwings. A $ from East Java has a broader 
white median area and a larger white transcellular spot of the forewings, but a more reduced white silvery 
band on the under surface of the hindwings, than my West Javanese specimens. Butterflies not very rare 
in the Monsun period especially in Sukabumi (West Java) and its surroundings, the most numerous at ele¬ 
vations of about 6 to 800 m. Larva, according to Dr. Piepers, on Cynometra cauliflora. — malayicus R. and J. malayicus.

of the island. <$ about of an inferior shape compared with tisamenus, median area considerably narrower, the 
small white submarginal spots of the hindwings decidedly larger. Under surface of the hindwings decorated 
with more pronounced reddish-brown crescents than the other neighbouring races. — luzonicus R. and J. is luzonicus.
