rather long precostal of the hindwings. Veins otherwise as in the genera Discophora and Enispe, yet the veins 
themselves are more delicate. In contradistinction to Faunis, the sexual hair tufts on the hindwings are wan¬ 
ting, and the forewings are apically produced into a decided point. Only two species are known, which must be 
included among the greatest rarities of the soutli-chinese-indian region. According to my observations they 
are twilight fliers, which first appear shortly before sunset, and inhabit damp valleys. 
A. amathusia. Two geographical races of this have been discovered, namely amathusia Heiv. from amathusia. 
North India, probably first obtained from Bhutan, and more recently found in Assam. Hewitson’s figure 
refers to the dry season form; $ upper surface yellow with a reel-brown longitudinal line beyond the cell, 
which crosses both wings, and with a dentate submarginal band on the hindwings. Under side with a 
small white ocellus in the anal angle of the forewing, and six tiny ocelli in the submarginal area of the 
hindwing. $ with blackish apex and lighter ochre-yellow median area on the forewings, also broader red- 
brown longitudinal bands on the underside. — peali Wood-Mas. considered by Doherty to be the wet peali. 
season form, and he is probably right in this, for the rounder wings and more prominent eye-spots, which 
also show through above and are distinctly black centred, form the only differentiating characters, peali has 
hitherto been observed only in Upper Assam. Flies in September to December, whereas amathusia is known 
also from the Khasia-, Garo- and Naga Hills. •—- oberthuri Stick, (described in Vol. I, p. 156 and there figured oberthuri. 
on PI. 49 e) is the rare west-chinese local form and considerably darker than the Himalaya race. 
A. lena Ath. (102 b) was discovered by Dr. Anderson in 1868 during the english Yunnan Expedition lena. 
in the south of that province, since which time only 6—7 <$S have been taken, all in Burma. The $ figured by 
us was unknown before my travels in Tenasserim, ivhere I took it at Tandong in the Karen Hills at an eleva¬ 
tion of about 1200 m. The $ is paler with more delicate black lattice markings and the underside is uniform 
light yellowish without the brown median area which the $ possesses. 
3. Genus: Xanthotaenia Westw. 
It Doherty’s statement, that the larva of the only species is entirely naked should be confirmed, then 
Xanthotaenia comes closest to the Satyridae, with which it further agrees in the closed cell, found elsewhere 
among the Amathusiidae only in Hyantis. Only one subcostal nervule is given off before the apex of the cell 
in the forewing. Precostal in hindwing straight and stout, as in Faunis. Hindwing with a tuft of dark hair on the 
submedian similar to Faunis faunula, but without the grey androconia-cavity of the latter. — Only one 
species known, which has become distributed from Tenasserim over Macromalaya with the exception of Java. 
X. busiris is easily recognized by the fiery yellow transverse band on the forewings, which stands out busiris. 
from a red-brown or dark brown ground according to the locality, busiris Westw. originally described from the 
Malay Peninsula, occurs in a very similar form also in Tenasserim and North Sumatra. Specimens from Tenasse¬ 
rim show a tendency towards extension of the yellow subapical bar. Martin states, that busiris flies throughout 
the whole year in high woods of the plains and foot-hills; the flight is higher and stronger than that of Faunis 
but just as erratic so that capture is more difficult. Martin always found the insect in channels recently cut 
through the primeval forest, drinking the water, and flying along them in a manner wich rendered pursuit 
impossible. The $$ are larger and have the yellow transverse band on the forewings lighter, busaris has only 
the second ocellus of the series on the under surface of the forewing complete in every respect, whereas 
3 larger ocelli on the underside of the hindwing are incomplete and rudimentary, as there is nothing left of the 
black iris excepting a slight trace outside the pupil. In Tenasserim busiris goes up to a height of 2000 m. $$ 
are rather uncommon. In West Sumatra a local form has been already developed, sadija subs]), nov. known sadija. 
by the narrowed rich dark yellow oblique band on the forewing, which appears proximally more sharply defined 
than in busiris and burra. The general colouring is darker red-brown than in busiris from North Sumatra, the 
band on the is just as splendidly yellow beneath as above, but white in the $ instead of pale yellow as 
in specimens from Borneo and North Sumatra. — burra Stick, may be known by the band on the forewing burra.

surface and the especially extensive violet or brown-red diffused bands on the underside. The ocelli on the 
hindwing are also more distinctly centred than in sadija from Sumatra. Nias Island, not uncommon. 
4. Genus: Hyantis Hew. 
Comes very close to the preceding and following genera in the closed cell, and two subcostal nervules 
given off before the apex of the cell as in Morphopsis. The apical boundary of the cell is almost straight, its poste¬ 
rior angle only slightly produced. Anterior discocellular very short as in Aemona, the central decidedly longer
