marginal area darker with some light and dark small scales almost forming a subterminal line that ends rtk... 
a whitish square spot at the proximal margin. At the distal margin some orange-red spots; fringes blackish- 
brown with silvery tips. Discocellular oblique with a pearl-streak in the centre and a small dot at the lower 
end, followed by a spot of small brown scales. Hindwing with a light grey base, defined as far as a line at 1 / 3 , 
which is lighter, by a brown shade. The whole area behind the line is dark brown, with a brown, dentate line 
composed of small crescents, which terminates and is flawed on vein 4 at 3 / 4 , once more shorter angled on 
vein 1 and indented on the submedian fold. On the transverse vein 2 white dots. Under surface olive- 
ochreous, hued with a flesh-colour, on the forewing more so. Both wings covered with grey streaks. Costa 
of forewing red; head, legs, and chest bright red. Collar yellowish red-brown; tegulae and patagia lilac-grey; 
distal half of thorax and basal segments of abdominal dorsum olive, rest of abdomen whitish, tinted olive; 
on the 4th ring a double brown transverse streak. It is very much like H. continua Warr. (50 f) from Milne Bay 
in New Guinea, but this species is above straw-coloured and beneath unspotted yellow. 1 <$ from the Upper 
Setekwa (Snow Mountains, Dutch New Guinea), taken by A. S. Meek in August 1910. 2 $9 from the same 
localityt aken few months later represent, in my opinion, the other sex of it, but they differ very much. They 
are dull flesh-coloured, with a yellow shade, faintly speckled dark, like in the grey <$. Cellular spot silvery 
with a slightly redder spot behind it, the whole wing as far as the distal line covered with small lustrous scales; 
distal line fine, more irregular, before the apex bent to the costal margin, edged with a deep yellow line which 
widens upwards and runs into the apex. Marginal area with a deeper red tinge, in 1 specimen with brownish 
black, but in such a way that the veins remain red; at the proximal margin behind the distal line a square 
white spot with dark streaks; hindwing with a yellow proximal line; the distal one yellowish or flesh- 
coloured, in the shape exactly like in the <$. Under surface like in the fj\ but much more yellow. Thorax, 
patagia and abdomen coloured like the wings. The sexes also differ by the contours of the wings. The U has 
the apex obtusely extended, the margin below indented and slightly flawed on vein 3; the 9 shows almost 
a square apex, the margin almost vertical as far as vein 3, then obliquely inwards. Beside these differences, 
however, the sexes exactly agree on the under surface of both wings as well as in the course of the distal 
line on the hindwing. 
0. aurata sp. nov. (50 i). Forewing deep yellow, streaked light brown, without a distinct proximal aurata. 
line; distal line finely tinged brown and flesh-coloured, extending like in the 9 of dissimilis, and pushed black 
at the costal margin; transverse vein with a fine silvery angular streak or small crescent in the centre and at 
the lower end, followed by a slightly darker spot. On vein 1, midway between the distal line and anal angle, 
a small square spot of blackish or white small scales; the area from the base to the distal line spread with 
small lustrous scales; marginal area of a deeper yellow. Hindwing at 1 / 4 with a flesh-coloured line, the 
distal line in the shape exactly like in dissimilis ; the apex hued with light brown. Under surface like in dissi¬ 
milis, but yellow without any flesh-colour. Head, thorax and abdomen yellowish, like the wings. 2 9$ 
taken at the same place and time with dissimilis. Owing to the differences between and 9 dissimilis, 
it seems to be impossible that these are the 9? °f continua Warr. which are yellow beneath. 
0. ustimacula sp. nov. (50 i). The 9 with dull yellow forewings spotted and speckled with black; uslimacuta. 
costal margin purer; a diffuse spot at the base, leaving free a yellow boundary before the black proximal line; 
in and below the cell some smaller spots; on the transverse vein an angular, silvery scaled line; distal line of 
variable thickness, blackish, broadly bordered with yellow, before the apex bent towards the costal margin; 
marginal area below with diffuse, irregular, black spots, and quadrangular black marginal spots below the 
apex. Hindwing with a yellow basal area and 2 black lines. At 1 / i a dark line and a distal one shaped as in 
dissimilis ; the median space between them filled up with black spots between the veins; marginal area with 
black spots between the veins, those at the apex being larger, and a large blackish spot at the anal angle. Under 
surface similar, the whole black markings reduced; the distal black line is twice broken. Face, palpi and legs 
reddish, vertex reddish-yellow, thorax grey, patagia flesh-coloured grey; metathorax blackish-brown; abdominal 
dorsum olive-grey, tinted brown. — Another specimen, ah. fulvata ab. nov. (50 i) is entirely flesh-coloured fulvata. 
and orange, except the basal area of the hindwing remaining purely pale yellow; the black spots are very much 
reduced, whereas a third specimen, ab. lilacina ab. nov. (50 i) has the forewing lustrous flesh-coloured as far as lilacina. 
the distal line, with a large black spot behind the proximal line which is distinct. Base of hindwing pale 
yellow. All 3 from the Oetakwa River, taken at the same time with the two preceding species. Types in the 
Tring Museum. 
0. triumbrata Warr. (50 i). Forewing yellowish-red; costal margin broad lighter, more flesh-coloured, triumbrata. 
and interspersed with small blackish scales; at y 3 an oblique, diffuse, deeper yellowish-red shading, and another 
one at 2 / 3 , neither of which reaches to the costal margin. A broad, deep yellowish-red marginal band containing 
an extinct dentate subterminal band, at the anal angle distinct, where it forms two dark spots on the veins 
1 and 2. Fringes yellowish-red, on both folds marked blackish-brown, and here in front of them a lilac-grey 
streak. Discocellular angular, upper half with a silvery line, the lower with a dot at the cell-end. Hindwing 
yellowish-red, the lines indistinct; transverse vein as in the forewing. Under surface more yellow, the striae
