not determined with certainty, which in Java is called Dawon-oundjek (perhaps a species of Pittosporum 
or Caryodaphne). The Pupation takes place on a leaf in a tlat, parchment-like cocoon. 
The genus is Indo-Malayan and extends northwards to North-East Tibet, whilst Celebes is the most 
eastern locality. The species are easy to recognise by the two widely separated pairs of slender spurs on 
the hindtibia and by the antennae. 
A. hypomelas spec. nov. Thorax above yellow, with a large black spot front and back on the hypomelas. 
metanotum; breast, legs and underside of the abdomen blue-black; upperside of the abdomen in the cf 
yellow and ringed with black, in the ? yellow, the end-segment entirely purple-black. In the forewing the 
two subapical spots completely merged together into a slightly reniform patch, the two posterior discal spots 
united to a rounded patch. Hindwing in cf and ? yellow, with black marginal band and black subcostal 
streak, which does not reach the marginal band. — Mandi, North-West India, and Chumbi Valley, Sikkim. 
A. walkeri. Antenna yellow before the tip. Abdomen in the cf above black with yellow rings, 
beneath for the most part 3 r ellow, in the ¥ beneath entirely black or the segments margined with yellow; 
penultimate segment in cf and ¥ above and beneath black; forewing with 6 or 7 yellow spots, the two 
outermost separated, rarely confluent. — In the Javan race, walkeri Moore, the black band of the hindwing walkeri. 
is rather broad and the abdominal segments in the ? above are thinly margined with black. — nigrescens nigrescens. 
Btlr. (8b), from North India, has somewhat less black on the hindwing than the Javan form and the 
abdomen of the ¥ is not ringed with black above, only the penultimate segment being black. In ab. confusa confusa. 
Btlr. the two subapical spots of the forewing are united into a reniform spot. — hainana Btlr. has in the ? hainana. 
somewhat larger yellow spots than the ¥ of nigrescens; from Hainan and Tonkin. — baliensis subsp. nov. baliensis. 
Marginal band of the hindwing narrow, abdomen of the ¥ above entirely yellow. Bali, 1 ¥ in the British Museum. 
A. fulvida Btlr. (8b), from North India and Burma, is very similar to the preceding species, but fulvida. 
smaller; abdomen in the cf above black, with yellow rings, beneath yellow, with indications of black rings, 
the penultimate segment black, the 1. ventral segment almost white, in the ¥ on the contraiy the abdomen 
above and beneath is yellow, the penultimate segment however is black beneath and laterally, the ventral 
plate of the 4. segment is also more or less black, whilst the two following segments are entirely yellow 
or only have small black lateral spots. The two subapical spots of the forewing are united into a reniform 
patch, but are separated in ab. diffusa Obertli. from Burma. diffusa. 
A. zebraica is more slender and smaller than the preceding species; abdomen above in both sexes 
ringed with black, beneath in the cf yellow, with some black, in the ¥ beneath black, with or without 
yellow margins to the segments. Antenna with white spot before the tip. Hindwing of the cf often hyaline 
in the middle. The anterior subapical spot of the forewing larger than the posterior one, in the ¥ the spots 
usually united into a reniform spot. — In zebraica Btlr., from North-West India, the underside of the zebraica. 
abdomen in the cf shows distinct black lateral spots and the penultimate ventral plate is entirely black; in 
the ¥ the ventral segments are margined with yellow. — In khasiana subsp. nov. (8a), from Assam, the khasiana. 
abdomen in the ¥ is entirely black beneath, whilst in the cf it is more extended yellow than in the 
preceding form, the yellow colour also occupying the middle of the penultimate ventral segment. — 
guttata Snell., from Sumatra. The subapical spots of the forewing separated; on the hindwing 2 black guttata. 
stripes run from the distal margin to the base, one behind the costa, the other behind the cell; the black ■ 
bands of the 3.—6. abdominal segments interrupted above. 
A. zebra Elw. With broader wings than the preceding species; abdomen in the cf (the ? is not zebra. 
known) black, with faint whitish rings. Forewing with 4 yellow spots, of which the subapical spot is 
composed of two. Hindwing with yellow central longitudinal spot. Fringes yellow, except at the apex of 
both wings. — Sikkim, 10,000 ft., in coll. Elwes. 
A. refulgens Hamps. (8b). The body coppeiy; abdomen ringed with white. Wings black; fore- refulgens. 
wing with a copper-coloured basal spot and 4 yellow spots, of which 2 are placed before the middle and 
2 distally to it. Hindwing yellow, bordered with black, the yellow area interrupted by a band running 
obliquely from the apex of the cell to the distal margin. — Burma; in the Museum at Genoa. 
A. discivitta Walk. (8 c). Forewing with a rather large subapical spot and a longitudinal line, which discivitta. 
reaches from the base almost to the spot. Hindwing with longitudinal patch from the base to beyond the 
middle. These markings pale yellow. — Only the cf known. Almora, North India, and the Nilgiris. 
A. lucasseni Snell. (8 b) is easy to recognise by the yellow longitudinal patches of which there are lucasseni. 
three each on forewing and hindwing. Abdomen above black, with jmllow spots (cf), beneath 3 T ellow. 
According to Snellen the sexes alike (is the ¥ really known?). — Java. The larva found by Piepers on 
Bambusa; not described. 
A. pulchra Drury. This Chinese form is only known to us from Drury’s figure. Forewing with pulchra. 
five yellow spots, the outermost rounded, the posterior one elongate wedge-shaped. Hindwing with broad 
black distal margin.
