ALLOTINUS. By H. Fruhstorfer. 813 
and submarginal macular series and accumulations of prominent, smoky-grey scales in the basal and inner- 
marginal region of both wings. 
A. taras initiates a small series of insignificant species of a predominantly dark-brown ground-colour 
of the upper surface and a brown, not grey or black marbled under surface. Clasping-organs of the most primitive 
formation, uncus-sheets not so long as those of the horsfieldi-posidion group nor as broad as those of the series 
of A. unicolor. The tip is also ventrally narrowed, the dorsal depression insignificant. The small ventral hooks 
relatively short, thin, the valve very short, of the plainest shape, slightly trough-shaped, but without any 
lamels or sharp points. Sexual spot relatively large, though not so very prominent as in the horsfieldi- group. — 
taras Doh., a rare form which has hitherto become known only from Tenasserim and Burma. The sexual spot taras. 
of the AA hardly contrasts with the ground-colour. The basal part of both wings is beneath almost whitish, 
the sharply dentate submarginal band of the forewing distinctly prominent. — battakanus Fruhst. (141 g) battalcanus. 
A brown-black, the forewings turning darker towards the distal margin. At the latter a black line. Cilia greyish- 
yellow. Shape of the forewings similar to that of A. fallax, without a sexual spot. Hindwings distinctly dentate. 
$ above somewhat lighter brown than the A, the wing-contours rounder, the hindwings more distinctly dentate. 
Under surface similar to that of sarrastes, but the reddish hue is confined to the distal margin of both wings. 
Ground-colour greyish-white with an extremely fine grey speckling. Both wings with a.series of minute black 
dots with a white periphery and a dark brown submarginal band. On the hindwings besides a median band 
and subbasal band. Montes Battak (Sumatra), February, March, collected in great numbers by Dr. L. Martin, 
but not recognized by de Niceville, not enumerated in the ,,Butterflies of Sumatra” and, therefore, a novelty 
for Sumatra. — narsares Fruhst. West Java; Sukabumi at an altitude of about 600 m. Smaller, above paler narsares. 
brown than specimens from Sumatra and Borneo. Under surface paler, resembling much rather taras Doh. 
from Burma than the insular vicarious types, Ground-colour dirty white, with unnoticeable, brown, small 
splashes. Rare, only 2 $$ in my collection. — sarrastes Fruhst. North Borneo. Habitus larger than that of sarrastes. 
Sumatra-faras, lighter brown. Under surface in the A darker smoky-grey, in the $, however, lighter than in 
taras. The brown spotting more intense and combined to more distinct bands. 
A. portunus was described according to the specimens I discovered in Java. The species is peculiar 
of the large Sunda Islands, but it will probably yet be discovered on the Malayan Peninsula. Both sexes some¬ 
what larger than A. taras Doh., but otherwise very near to this species. The $ has rounder wing-contours. 
Under surface in the A uniformly grey-brown with a reddish or violet reflection. The $ is whitish with series 
of red-brown spots. Both sexes exhibit a series of extremely neat, black anteterminal dots on both wings. 
Uncus-sheets knife-shaped, more slender and longer than in A. taras. The small ventral hooks are somewhat 
stronger than in taras. The uncus-sheets are dorsally not indented. Valve of the plainest formation, trough- 
shaped, somewhat longer than in A. taras. The butterflies chiefly inhabit the mountains, being apparently 
most common on the Kina-Balu. - — portunus Nicev. from the Volcano Gede from an altitude of about 1200 m. portunus. 
Under surface only unnoticeably marbled in red-brown. -— maitus Fruhst. from Sumatra. A A from the Battak maitus. 
Mountains differ from ‘portunus Nicev. from Java by the much lighter ground-colouring beneath, which we 
might denote as ^greyish-white, instead of brownish-violet as in pyxus and reddish-brown in portunus. The 
brown-grey speckling is lighter than in the portunus-races known. The $ approximates the most the $ of pyxus 
from Borneo, from which it differs by its more purely white ground-colour and more delicate brown-grey 
marbling. — pyxus Nicev. (= waterstradti Druce) (141 i) is before me in 36 specimens from the Kina Balu. pyxus. 
Under surface of the AA more distinctly spotted than in those from Java and Sumatra. — absens Druce is absens. 
a discoloration exhibiting only the more prominent macular bands of the under surface, whereas the finer 
brown lines are absent. 
A. strigatus was first recognized in Borneo, whilst it is ascertained here by myself as a novelty 
for Java and Sumatra, de Niceville confounded the A A with A A °f A. portunus. In size strigatus resembles 
A. horsfieldi of which it has the same large anclroconium of the forewing in common. The $ likewise reminds 
us of the light-coloured $$ of some races of horsfieldi by a yellowish, discal brightening of the forewings. By 
its preponderate^ red-brown marbled under-surface strigatus forms an intermediary between the A. taras 
and A. horsfieldi groups, strigatus is so far known only from the large Sunda Islands, we must, therefore, try 
to discover it yet on the Malayan Peninsula. Like in A. portunus there are three insular races. — strigatus strigatus. 
Moulton (141 i). Mr. Moulton had the great kindness to hand over his co-types to the British Museum, so 
that, I was able to look at this sharply separated race there. Size about that of A. horsfieldi Moore. Under 
surface distinguished by prominent, grey-brown, broad macular bands the components of which exhibit a reddish 
admixture. Another conspicuous mark are anteterminal marginal dots of both wings. Pulo Laut, Sarawak 
(Moulton), Kina Balu, Sintang (Coll. Fruhstorfer). -—• dositheus Fruhst. West Java, very rare. Under dosithcus. 
surface lighter grey, with more delicate brown maculae than in the Borneo-race. — eupalion Fruhst. from North eupalion. 
East Sumatra. Under surface covered with more intense brown maculae than strigatus from Kina Balu. Disco¬ 
vered by Dr. L. Martin, but confounded with A. portunus by de Niceville, and just as little enumerated 
in ,,Butterflies of Sumatra” as A. taras, so that the species was af first ascertained for Java as well as for 
Sumatra by myself.
