Ae. prasina Warr. (8 e). <$ less variegated above than in most of the group, the forewing, however, 
with the basal patch and median area filled in with brown. Hindwing beneath with the post median line angled 
or bent outward at the 3rd radial. $ rather larger, with costal edge reddish, median area not darkened, the 
reddish subterminal shading strengthened, sometimes extended. New Guinea and the adjacent islands, the 
type from Eergusson. — spadicocampa Prout , from Biak, is smaller, with larger cell-spots, postmedian line 
thickened in the middle, the red markings amplified. —- angustifascia Prout, from Dampier Island, has the 
median band of the forewing narrowed. — defasciata Prout, from Rook Island, New Britain, (loc. typ.), New 
Ireland and New Hanover, has the median band broadened, especially posteriorly, and remaining predominantly 
green, the band beyond it amplified, though less brightly coloured than in spadicocampa. Superficially this 
race recalls viridimedia. — louisa subsp. n., from St. Aignan, is in both sexes rather weakly marked above, the 
median area rather narrow, making a transition in this respect towards angustifascia, while in the increase 
of the green ground-colom in this area it more approaches defasciata. Type in Mus. Tring. 
Ae. albifusaria Walk. (8e, f). The A differs from all the allies in the prevalence of purple coloration 
on both wings above. The underside is similar to that of prasina, but with the blackish markings broader and 
more intense; on the hindwing the postmedian line and the distal band are confluent posteriorly, the intermediate 
white band consequently incomplete. The typical £ is recognizable at a glance by the white patches on the 
upperside and is prevalent on Mysol (the type locality), in W. and N. New Guinea and perhaps at higher allitudes 
in British New Guinea. — discolor Warr., from Korrido, is possibly a $ aberration, but I believe merely a 
discoloured example. — suffusa Warr. (8 f) is scarcely distinguishable in the q from the form albifusaria, 
but its $ lacks the white patches. It differs from that of prasina in its rather smaller size, differently shaped 
median area, absence of reddish costal shade etc. Warren mistook a slightly suffused ab. of prasina for 
the $ to suffusa. D’Entrecasteaux Islands (loc. typ.) and from coastal regions in British New Guinea. 
14. Genus: MetalJolopliia Warr. 
This genus is in a measure intermediate between Aeolochroma and Terpna and I am now doubtful 
whether it should not be made another section of the latter. Face not protuberant. Antenna of A not pectinate. 
The type species ( vitticosta ) is well distinguishable in having the abdominal crests metallic and the wings of 
the $ narrowed, but the other species which I have associated with it are transitional. Evidently Indo-Malayan 
in its origin, though one species has straggled into Central China. 
M. vitticosta Walk. (8 f). Unmistakable in the generic characters given above and in the broad 
pale subcostal streak of the forewing. Described from Sarawak, also known from the Malay Peninsula and 
Sumatra. 
M. subradiata Warr. has the same large, obliquely placed, somewhat reniform cell-spots as the allies, 
but has the base of both wings dark-clouded and a somewhat Pingasa- like underside, with yellow base and 
broad purple submarginal band, somewhat broken by pale veins, the cell-spot large on the forewing, obsolescent 
on the hindwing. Penang (type) and Borneo, very rare. 
M. opalina Warr. (8 f), from Sikkim, is similar to arenaria (vol 4, pi. 1 e), but with the £ antenna simple, 
the coloration rather darker, but with whitish admixture on the forewing anteriorly, the lines strongly den¬ 
tate. Underside yellow at base, otherwise pale purple with darker cell-rings and on the fore wing a longitudinal 
streak in the cell. 
M. ocellata Warr. (8 f). Similar to the preceding and following species. Upperside with ill-defined 
green bands, but without blackish lines. Forewing beneath white with the cell-spots and bands deep pimple, 
much as in arenaria, but with the long purple streak behind the median and its second branch reduced to a 
small spot behind the cell. Ivhasis. 
M. arenaria Leech (= danielaria Oberth.) has been described and figured in Mol. 4, p. 12, pi. 1 e, 
but is now known also, and in better specimens, from Burma and Tibet. The antenna of the A is subpectinate. 
The maculation of the underside is purple, as in the allies. 
15. Genus: Terpna H.-Sch. 
Face more or less protuberant (except in pictaria and perhaps neonoma). Antenna of A nearly always, 
of $ sometimes pectinate. Pectus densely hairy. Abdominal crests well developed. Forewing rarely with distal 
margin very oblique. Hindwing generally with abdominal margin elongate. 
A somewhat heterogeneous assemblage of Indo-Australian species of robust build which do not fall 
naturally into either of the other recognized genera.
