ALLOTINUS. By H. Fruhstorfer. 
of 5 obliquely arranged maculae. Both the wings covered with an anteterminal series of brown dots. Hindwings 
white, densely covered with grey dots and more prominent brown maculae and splashes. -—- It may be that 
' parapus represents only a considerably modified insular race of A. apus Nicev. But as the position of the 
median spots of the hindwings of parapus is different, I ranged the Borneo-form as a species of its own. North 
Borneo, (Kina-Balu): 1 <$ Coll. Fruhstorfer. 1 co-type I handed over to the British Museum. 
b) Group of species Paragerydus Dist. 
A. nivalis denotes the most insignificant species of this group. We meet with it in Macromalayana 
and, in a vicarious type, in the Philippines. Upper surface in both sexes unicolorously clark-brown. <$ with 
a delicate, yellowish sexual line being formed by the base of the somewhat thickened, unsealed anterior median. 
$ with rounder wings. Under surface whitish with black anteterminal dots being clistally set with white, a 
nivalis, black costal spot of the hindwing and brown longitudinal bands in the discal and submarginal region. — nivalis 
Druce (141 g) is the largest form. The apical part of the under surface of the forewings more extensively and 
magaris. more intensely dusted with brown than in the neighbouring races. -—- magaris Fruhst. with the type from North 
East Sumatra. Smaller than nivalis. Forewings more pointed. Under surface more copiously and more deli- 
lenaia. cately dusted with brown. Dr. Piepers discovered quite a similar race also in West Java. — lenaia Fruhst. 
Just as small as magaris. Under surface, however, faded, almost purely white with uncommonly neat, hardly 
snbstrigosa. recognizable, brown macular series being combined to small, delicate bands. Island of Nias. -—■ substrigosa 
Floore from the Mergui-Archipelago, also passes over to the continent of Tenasserim and is found to the sonth 
as far as Perak. The under surface is just as faded as in lenaia , though the brown splashes are somewhat more 
distinct. 
feldcri. A. felderi Semj). is very rare in the Philippines, but it is reported from the north (Luzon) as well a 
the south (Mindanao) of the archipelago. I am without any examples, so that I am unable to ascertain, whethe 
felderi is to be considered as a species. Judging from Sempers figure, it is only a geographical race of A. nivalis. 
A. aphocha is an insignificant and slightly differing species which, in most of the collections, is con¬ 
founded with small A. horsfieldi Floore and A. posidion Fruhst. Martin and Nicevtlle did not recognize it, 
so that I may ascertain it as a novelty for Sumatra, Engano, Penang, Singapore, Java, Bali, and Celebes. 
aphocha slightly exceeds A. nivalis in size, the shape of the wings is entirely more roundish, the sexual spot 
of the forewings of the is somewhat broader and grey. It is somewhat shorter than in A. unicolor Fldr. 
The hindwings of the $$ are above bordered with a pure white, extraordinarily sharply and pointedly dentate. 
Under surface chalk-coloured, sometimes with a yellowish hue. The anteterminal dots are more distinct than 
in A. unicolor , the submarginal spots less prominent. The other marbling as in A. posidion Fruhst. The clasping- 
organs are more slender than in the genuine Allotinus, dorsally slightly caved in; valve extremely 
aphocha. characteristic, more slender, more pointed than in A. unicolor, with 2 lamels. — aphocha Kheil (141 g), ori¬ 
ginally described from Nias, also from Engano, Penang, Singapore, and Deli (Sumatra) in my collection, is 
rebilus. distinguished by an almost purely white under surface. — rebilus Fruhst. is a form being darkened beneath, 
enatheus. with a blackish, instead of brown, marbling. Distributed over the whole of Borneo. -— enatheus Fruhst. from 
West Java and the island of Bali. Under surface chalk-coloured with light-brown, instead*of greyish-black, 
zitema. dots. -— zitema subsp. nov. was discovered by myself near Tontoli (North Celebes) from November to December. 
9 considerably more imposing than the Macromalayan allies. Under surface, corresponding to the character 
of all the Gerydinae from Celebes, more densely dotted and spotted with a greyish black. 
A. unicolor. An insignificant, rare species which has hitherto been often confounded with allied species. 
Inferior in size to A. horsfieldi and posidion, differing from all the allies by the distinctly roundish forewings 
reminding us of A. aphocha Kheil. The hindwings of the $ either entire, or in contrast with aphocha only with 
minute teeth. The sexual macula on the forewing above smaller than in posidion. Under surface white, but 
not so purely chalk-coloured as in paetus Nicev. Basal part and cell of both wings with thick, browm, little 
dashes. Both wings are, besides, distally from the cell, crossed by a remarkably pronounced series of brown 
spots being combined to a loose band. Uncus shorter, broader, dorsally less deeply indented than in A. aphocha. 
The species having been hitherto known only from Singapore, Penang, Borneo, is here ascertained for Engano, 
Java, Lombok, and Celebes. One specimen was found in the Berlin Museum, the patria being labelled as 
unicolor, from Mindoro. -— unicolor Fldr. (141 i). The type, a $ from Singapore, is before me by the kindness of Dr. 
Jordan. In the British Museum there is a $ from Penang. Dr. Piepers has a from West Java. Distant 
knew the species, though he figured a $ as A. horsfieldi. Moulton mentions A. unicolor from Borneo; I am 
without any specimens from there. We may be certain to expect unicolor from a number of other insular habitats; 
the more so as it was confounded in collections both with A. posidion (141 g) and with A. aphocha (141 g). 
Size analogous to the most imposing $$ of A. aphocha, from which it scarcely differs above. Under surface 
discernible from all the Allotinus (even A. paetus ) by the interrupted series of prominent, light-brown sub¬ 
marginal spots of the hindwings, the anterior ones of which are removed far inwardly. On the forewings, the
