“‘This species varies greatly in size, the smallest specimen examined being a female 
and expanding only 1°3 inches. As Mr. Hewitson pointed out, an excellent differential 
specific character is found in the spot-like projection to the discal fascia on the underside 
of the forewing ; but when the describer states that in the female the last spot of this fascia 
also projects outwardly, he has described what is found on none of the specimens now before 
me.” (Distant, 1. c.) 
Mr. Distant identifies this species with the Amdlypodia ampkimuta of Felder, and the 
A. hypomuta of Hewitson. As I have stated elsewhere (p. 276), not only do I think that 
those two species are distinct from one another, but also that the species now under discussion 
is distinct from both, not only by its having a tail, which the others lack, but also in its 
coloration and markings. Two male specimens captured in Singapore which I have received from 
Mr. W. Davison, agree almost exactly with Mr. Distant’s description and figure of the same sex, 
the only point of difference being that one subcostal spot only is described to the forewing on the 
underside, while my specimens have two. The species is, I think, a good and easily recognis- 
able one. Itis nearest to 4. aida, mihi, from which it may be known in the male having the 
outer black margin of the forewing on the upperside narrower ; the colour of the ground on the 
underside is also very different, being dull brown, without any of the purple gloss, which is so 
very characteristic of A. aida. I amenabled to include it amongst the Indian species owing 
to Mr. W. Doherty having obtained a single male at Myitta, in the Tenasserim Valley, Burma, 
in the cold season of 1888-89.

A. basalus is a very distinct and easily-recognised species. On the underside of the 
forewing the inner margin is broadly pale, the apex irrorated with grey and glossed with purple, 
all the markings very large and surrounded narrowly with whitish, a good-sized spot near the 
base of the cell, a large spot at its middle, a very large spot at its end ; a very broad discal 
band, consisting first of four spots placed obliquely outwards, then two spots shifted inwardly 
and breaking the line, often with a seventh small separated spot below the first median 
nervule, the usual submarginal and marginal obscure fasci. Hindwing heavily irrorated 
with whitish, the spots more numerous than usual and prominent ; in addition to the usual 
four basal spots, there are two large spots near the base of the wing above the costal 
nervure, a large spot below the outer of these two spots beneath the costal nervure, a large 
spot in the middle of the cell, and one closing it, with two spots below the last divided 
by the first median nervule ; the usual discal band very irregular, its anterior portion 
consisting of two very large and prominent spots; a prominent submarginal lunular line; 
the anal lobe black, with a sprinkling of metallic dull green scales beyond. 
This species occurs rarely in the neighbourhood of Shillong, and Mr. Wood-Mason 
obtained one female at Silcuri on 31st May, and another at Dhurmkhal on 14th July, 1884,
