they are generally speckled with white within and at the sides, and insome cases adorned with 
a few silvery spots. ody deep blackish-brown or purple above, and ferruginous-brown and 
hairy underneath. Antenne are nearly throughout ferruginous-brown, The intermediate ¢az/ 
is narrowly tipt with gray. Za7sz of the male covered above with small, and of the female with 
large scales, which appear pendulous under the lens. FEMALE. UPPERSIDE, doth wings 
blackish-brown, with a brilliant cyaneous patch, adorned with a rich silvery gloss of a more 
jntense tint at the base, and defined in both wings according to the outline of the wing, being 
separated from the margin by a broad regular border of the blackish-brown ground-colour. 
UNDERSIDE, both wings as in the male.”’ (Horsfield,1.c.) Dr. Horsfield places this species in 
his three-tailed group, but the tail at the extreme anal angle and the one at the termination of 
the second median nervule are extremely small. 
Larva limaciform, black, marked with longitudinal reddish-brown and pale yellow stripes ; 
the segments well-defined, the sides furnished with numerous short bristly hairs ; the head small ; 
the second segment unusually large, pale yellow, marked with a median fine black line, then on 
each side a U-shaped mark, and lastly a small round dot placed posteriorly ; each segment bearing 
laterally a prominent round dot placed on a pale yellow patch ; the third to the penultimate seg- 
ment inclusive of nearly equal size, the last segment anteriorly cut off or flattened. PUPA rather 
elongated, smooth, the head rounded, the thorax but slightly humped, the tail pointed ; colour 
pale reddish, streaked and marked with dark brown and black. Described from the figures 
in Horsfield and Moore’s Catalogue. Dr, Horsfield says that in Java ‘‘ the larva feeds on the 
leaves of several species of Zugenia and Caljptranthes,” and that the insect occurs commonly 
in the island. 
I have seen but a single specimen of this species, a male from Borneo in the collection of 
the Indian Museum, Calcutta. The species may be known from every other by the very broad 
regular dark brown band on the underside of the hindwing, which extends across the disc from 
the second subcostal nervule to the abdominal margin ; the band anterior to this is pale purple, 
and bears a series of dark brown spots, the first on the costa is large and quadrate, the next 
in the middle cf the wing is smaller, the third in the submedian interspace oval and the 
smallest of all. A specimen in the British Museum from Moulmein recorded by Mr. butler 
is the only knowledge I have of the occurrence of A. afidanus within strictly Indian limits. 
Mr. Distant considers it to be a very rare species in the Malay Peninsula, Captain Pinwill 
obtained it at Malacca, and Mr. Godfery at Singapore. 
Since the above was written I have seen a female of 4. apidanus taken by Mr. W. Doherty 
at Mergui in the cold weather. He writes regarding it :—‘‘ Mr. Distant makes no mention of 
the singular scarlet costal area at the base of both wings below in this species, though they had 
long ago been observed by Cramer, Godart, and Horsfield. They are occasionally present, though 
much less marked, on the forewing of some of the Himalayan species of this genus, as Mr, de 
Nicéville has shewn me.” 
“This species is the type of my genus /7os, the life-history of which I hope to publish 
before long. I have taken it in Eastern Java, and slightly different forms occur in Celebes and 
in the mountains of Sambawa.”’
