PLATYPTHIMA; HARSIESIS. By H. Fruhstorfer.

pupils stand out distinctly. hindwing beneath predominantly black with a yellow discal spot. Length 
of the forewing 25 mm. Only one pair yet known, discovered by Meek in the Aroa district. 
9. Genus: Platyptliinia R. A- J. 
Likewise near to Hypocysta and hence also to Argyronympha , mainly with the same structure. Eyes 
hairy. Wings short and broad. The genus, the type of which is the figured ornata , embraces also a few species 
which for want of material cannot yet be definately proved to belong here. Only three certain species known 
as yet, all from British New Guinea. 
P. ornata R. & J. (99 c). Under surface of the forewing unicolorous brown, but hindwing with varie- ornata . 
gated markings, the arrangement of which somewhat recalls certain Pedaliodes from South America. Beyond 
the cell a spar-shaped yellowish stripe, distally bordered by a similar but red-brown one. Two larger round 
black, white-dotted ocelli with reddish bordering in the submarginal area. Hindwing in addition with a violet, 
metallic median band and a similar subterminal stripe. From 2000 m. Flies November to February. 
P. simplex R. & J. Body and upper surface of the wings as in ornata, the white area of the forewing, simplex . 
however, distally more rounded, the black admarginal line of the hindwing standing out somewhat more distinctly 
from the first median onwards. Under surface: forewing slightly tinged with purple, but with no trace of eye- 
spots, in place of which there is a fine undulate line, bordered by a small olive-coloured stripe. Hindwing dense¬ 
ly scaled from the base to the apex of the cell, then a band-like olive-coloured median area, which is accom¬ 
panied distally by a black and a metallic line. In addition about 5 ocelli and a metallic admarginal band. Length 
of the forewing about 18—20 mm. Only 2 known, from the Aroa region. 
P. decolor R. <k J . Body above dark brown, a broad lateral line on the palpi and behind the eyes decolor . 
cream-coloured. Wings above brown, forewing in the basal half of the cell densely haired. Under surface: 
forewing with dark apex, a narrow, angled, cream-coloured band and three small ocelli. Hindwing dark olive- 
coloured, sprinkled with cream-white and chocolate-coloured scales, a yellowish white band, touching another 
narrower one, and four white ocelli. Length of the fore wing 20 mm; only of this charming species as yet 
discovered. Locality likewise the upper region of the Aroa River, British New Guinea. 
10. Genus: Harsiesis gen. nov. 
The single certain species of this hitherto overlooked genus has been united with Hypocysta , from which, 
however, it is easy to separate by the broader cells on both wings and the longer upper discocellular of the fore¬ 
wing. Moreover in Harsiesis two subcostal veins arise far before the end of the cell, in Hypocysta only one, 
whilst the second arises directly at the end of the cell. The very long lower discocellular of the forewing more 
deeply incurved, not almost rectilinear. The $ bears in addition 3 tufts of hair at the anterior margin of the 
cell and on the submedian of the hindwing, which are absent in Hypocysta. Precostal straight, distally not 
excurved as in Hypocysta. Hitherto only known from the Papuan region and apparently like Hypocysta not 
even extending on to the eastern satellite islands of New Guinea. 
H. hygea, of which there are three branch-races to record: noctula subsp. nov. (93 d), which is above noctula . 
more uniform dark blue-grey than hygea from the Aru Islands. The subanal eye-spot on the underside of the 
hindwing is much smaller than in hygea. German New Guinea, very rare. Flies in January, mostly on the spurs 
of the mountains. — hygea Hew. Above differing from noctula in the paler grey, distinctly defined apical area hygea . 
of the forewing. The silver-coloured median band on the underside of the hindwing scarcely half as broad as 
in noctula. Hitherto only recorded from the Aru Islands, apparently not extending to the Key Islands. Ober- 
thItr records an allied form from Andai near Dorey in Dutch New Guinea. — jobina subsp. nov. is the most jolina . 
pronounced geographical subspecies. Upper surface transparent, light slate-grey, with brilliant blue metallic 
gloss in the cell. Under surface of the forewing with a broad whitish median area, the metallic band much restric¬ 
ted and narrowed by the'’large ocelli. Jobi. 
H. hecaerge Hew., described from New Guinea and certainly very rare, as since the time of Wallace liecaerge . 
and. Hewitson (thus the fifth and sixth decades of the last century) it has not again been brought to Europe 
and Hewitson’s type is perhaps the only example known. $ differing from hygea Hew. in the more rounded 
wings and the presence of a large apical ocellus on the underside of the hindwing, so that the red-brown band 
encloses a double eye-spot. Forewing lighter grey than in hygea-Q, with a very broad pale yellow band, which 
is reproduced beneath. It is not impossible that hecaerge is only a pale aberration of hygea. Dutch New Guinea.
