the forewing, as well as by its small shape and the almost blackish-grey colouring of the upper surface. On 
the under surface, bajanus reminds us of A. paetus Nicev. (141 i) by the almost chalk-coloured ground-colour 
and a prominent submarginal band of blackish-grey spots. Also the cellular, subbasal and anteterminal maculae 
are remarkably developed as in paetus. — damodar Fruhst. (141 i). A known from South Celebes, $ from North damodar. 
Celebes. The characteristic mark of the collective species, the wings being distinctly rounded off, is particularly 
distinct in this race. The uncommonly narrow sexual spot is longer than in the Macromalayan allies. Under 
surface bluish-white, the submarginal macular band still more prominent than in A. bajanus Fruhst. from Lombok, 
in the $ from North Celebes, however, again somewhat more faded. — leitus subsp. nov. Habitus scarcely leitus.

A. leogoron spec. nov. forms a peculiar transition from A. unicolor (141 i) to A. posidion (141 g, h). icogoron. 
From the unicolor-iovm.fi known to me it is immediately distinguishable by the roundish and very broad sexual 
stripe of the forewing, anatomically by the short, stout shape of the uncus-plates. The distribution of the 
macular series of the forewings beneath resembles that of A. unicolor, the contours, however, are still less distinct. 
As to its habitus, A. leogoron approximates A. posidion. $$ of the size of the $$ of posidion. Sumatra, South 
Borneo. 
A. paetus, an interesting, easily recognizable species, considerably superior in size to the species ■paetus. 
having been dealt with so far, also at once discernible from unicolor (141 i) and aphocha (141 g) by the long, 
narrow, prominent sexual spot on the upper surface of the Uc? forewings, by which it reminds us of A. liors- 
fieldi. The chief characteristic is exhibited beneath by the ground-colouring being of a pure chalk-white parti¬ 
cularly in the $. The dotting of the forewings is something like that of A. unicolor, but the anteterminal dots 
are more pronounced, the submarginal ones more isolated. In addition, another third, prominent, discal macular 
series. Uncus slender, with an insignificant, dorsal depression. Valve, compared with A. unicolor and aphocha, 
short, stout without any lamels. Two geographical races beside which we may expect another vicarious form 
from the Malayan Peninsula. The species will perhaps be also found yet in Java, paetus N icev. (141 i) from paetus.

A. posidion. smaller than A. horsfieldi, but superior in size to A. unicolor. Immediately discernible 
from A. horsfieldi by the narrower and shorter sexual spot of the forewing, from A. unicolor by the more 
pointed forewings. Under surface similar to that of horsfieldi with a less pregnant dotting. Hindwing of the 
$ very distinctly dentate, but the points are shorter and blunter than in A. horsfieldi. posidion is easily separated 
from A. unicolor by the fainter submarginal spots of the forewings. A. posidion always occurs beside A. hors¬ 
fieldi, and is much more common than A. horsfieldi with which it was hitherto confounded, and is immediately 
discernible from A. horsfieldi by its smaller shape. The clasping-organs exhibit considerable differences, being 
the more conspicuous when considering the general resemblance of the genitals of all the Gerydinae. A large 
series of posidion compared with a similar one of horsfieldi-iorms, yields the following differences: Shape, con¬ 
sidering the small size of A. posidion, considerably smaller. The uncus-plates shorter, stouter, dorsally but 
slightly sinuous. The small ventral hooks shorter, neater. Valve scarcely shorter, but much broader, without 
the rostriform point by which horsfieldi is distinguished. The species is distributed from Burma all over Macro- 
and Micromalayana as far as the Philippines. — atacinus subsp. nov. is before me only in the female. Upper atacinus. 
surface remarkably light brown with a broad, dull greyish-yellow transcellular stripe of the forewing. Hindwing 
remarkably sharply dentate. Under surface peculiarly greyish-yellow with an uncommonly neat, red-brown 
marbling and indistinct submarginal spots. The form figured by Niceville as A. horsfieldi (in Lep. Indica, 
t. 26 fig. 156), from Burma, pretty surely belongs to atacinus as its U- — myriandus Fruhst. remains in the myriandus 
female above unicolorously brown, $ with a short —■ compared with A. horsfieldi also very narrow — grey 
sexual spot of the forewing. The under surface varies, being sometimes grey, sometimes yellowish-white. The 
speckling and bands more prominent. Type from Sumatra. Also from the Malayan Peninsula, Nias, Engano

by the paler brown ground-colour from the other Macromalayan allies. Under surface yellowish white, some¬ 
what more pregnantly speckled than in atacinus. ■ — eurytanus Fruhst. Under surface greyish-white with an eurytanus. 
uncommonly dense, but delicate, lightgrey speckling. Both wings are traversed by a series of black, oblong, 
small submarginal dashes, as well as by a series of strong, crescentiform postdiscal maculae which, however, 
are less distinctly prominent nor as pregnant as in A. unicolor. West Borneo, Sintang; flying in April. — 
molionides Fruhst. The difference of this form from the Javanese, already struck Elwes who wrote to Niceville molionides.
