S. scopas Stgr., likewise from Palawan, has the size and shape of the preceding species, in the disc scopas. 
of the forewing a group of 3 small spots, and the under surface of the hindwing is whitish, finely powdered 
with greyish brown, and with dark spots at the distal margin and in the disc. 
10. Genus: lasiibrix Wts. 
Morphologically distinguished from the preceding genus by the lower median branch of the forewing 
branching off here directly before the cell-end. In the habitus, however, they differ enormously from them. 
By the broad wings being invariably flatly spread out they much rather resemble the European Thanaos tages, 
whereas the Suada exhibit the approximate flight and attitude of the European Parnara , such as nostrodamus. 
8 forms are known, being confined to India with the Sunda Islands, where, however, they sometimes number 
among the most common lepidoptera. 
I. salsala Mr. ($ = luteipalpis Plotz) (168 d). Above and beneath dark brown, almost black. The salsala. 
d shows above a beautiful golden brown coating and a row of spots which becomes more conspicuous in a 
certain light, extending from the cell-end of the fore wing to the centre of the hind-margin; the $ forewing 
exhibits a postmedian angidar row of hyaline spots. Beneath the golden brown coating is still more beautiful; 
in the $ the chain of hyaline spots is continued on the hindwing by 3 or 4 white spots through the centre; 
in the there are often hardly traees of these small spots. From Sikkim through the whole of India as 
far as Ceylon. — vasuba Fruhst., from Tonkin, is a name for larger specimens; they are darker than Indian salsala, vasuba. 
the row of white spots on the forewing of the $ is very distinct, but the row of dots beneath is almost entirely 
absent. — The salsala number in South India and Ceylon among the most common lepidoptera bustling about 
on every little green place, preferably resting on dwarf bamboo and Mimosa, with their wings widely spread 
out. The larvae presumably all live on bamboo. 
I. stellifer Btlr. (168 d) was repeatedly treated as a race of salsala , what has been contested again stellifer. 
and again. Very similar to salsala, above blacker owing to its being less coated with golden brown, the dots 
on the forewing fine though distinct and so arranged that one is situate above the sub median area, one in 
the cell-end, and a third before the centre of the distal margin. Beneath there are behind the white spots of 
the hindwing some more small orange spots. Burma, Malacca, Sumatra, and Java. — niasicus Fruhst., from niasicus. 
the Isle of Nias, is smaller, darker, also beneath jet-black with very neat pure white dots. — Larva light green 
with a yellowish head with black marks; on bamboo. Not rare. 
1. sindu Fldr. (168 e). This species is at once recognisable by the forewing, which is otherwise uni- siyidu. 
coloured blackish brown, exhibiting a miniate transverse diffuse spot which is distinct on both sides. Malacca 
and Sumatra. Rarer than the preceding species. — yamanta Fruhst., from Borneo, is distinguished by a broader yamanta. 
red band of the forewing. — obliquans Mab. are specimens from East Java, which Fruhstorfer took there, obliquans. 
but which are not mentioned by Piepers in his Javanese Hesperidae, what may be due to the great exterior 
resemblance of sindu with the Koruthaiolos likewise exhibiting a red spot on the forewing. 
I. latifascia Elw. (168 d). In this species there is a large oval red spot in the distal half of the forewing, latifascia. 
Sumatra, Borneo. A West Sumatran $, according to Fruhstorfer, shows a still much broader band than 
the figure. 
11. Genus: Aeromaclius Nic. 
On p. 342 of Vol. I this genus has already been dealt with by Mabille who enumerated 6 forms 
there, being partly confined to the palearctic region ( chinensis Elio., piceus Leech , inachus Men., nanus Leech, 
catocyanea Mob.), partly passing over to it, such as A. stigmata Mr. On the whole, 12 species of the genus are 
known now, all of which are easily recognised by the under surface of the hindwing. 
A. stigmata Mr. (= discreta Plotz nee Elw. & Edw.) (168 e). In Vol. I we published an enlarged stigmata. 
figure of this species (2:1) (according to Leech), whereas here we figure the species in its natural size. 
Accordingly the palearctic specimens exhibit a much lighter, more brownish-grey ground-colour of the hindwing 
beneath, and the two chains of dots in the marginal thirds of both wings beneath are of a pure white. Accordingly 
the palearctic form of stigmata is more similar to the form discreta Elw. <£• Edw. (nec Plotz) which is distinguished discreta. 
by the white markings being replaced here by a dingy light brown colour. This form extends far into China, 
whereas typical stigmata come particularly from North India. — javanicus Elw. ( = discreta Piep. d ■ Snell.) javanicus. 
(168 e), from West Java, shows the anteterminal spots above and beneath quite obsolete, and is almost uni¬ 
coloured dark. — In jhora (168 e) the under surface of the hindwing is uniformly tinted with a greyish green; jhora. 
above it is dark olive brown, and the small light anteterminal spots are absent as in the Javanese form or 
they are only feebly marked. It is reported from Sikkim and, if it flies together with typical stigmata, it may 
be a distinct species, what is also supposed by Elwes and Edwards by reason of their anatomical examinations.
