to the tail; the tail itself more prominent and the concavity below it stronger. Forewing beneath yellow, 
the area below the cell and the marginal area pink; outer line in the lower half dark pink, sometimes black 
and thick. Hindwing beneath quite pink, except the base of the costa and the abdominal margin. — In ab. 
seminigra ab. nov. (50 a) the hindwing above is entirely suffused with blackish-brown, whereas the ground- wminigra, 
colour of the forewing is a lighter grey; these specimens are from the Ninay Vally; those from the Aroa R. 
are smaller, with darker forewings; the black hindwings are mixed with reddish. 
U. praecisa sp. nov. (50b). Forewing olive fawn-coloured, intensely tinted reddish; costal margin pracrim. 
with 2 usual small dark-spots, but the lines proceeding from them very indistinct; marginal area as usual darker 
red-brown; before the apex a dull yellow spot; fringes with white tips. Hindwing deep red, slightly speckled 
with brown, with some lustrous scales along the margin; before the black, white-tipped fringes a bright red 
line. Margin of hindwing straight from the apex to the small tail which is very prominent. Under surface of 
forewing rosy flesh-coloured with a diffuse golden yellow spot before the apex; margin and outer line with 
small violet and glossy scales; between veins 4 and 5 three blackish-brown spots in one line; hindwing quite 
pink with black fringes. 1 $ from the Oetakwa R. (Snow Mts. in Dutch New Guinea), at an altitude of 3500ft., 
October till December 1910, captured by A. S. Meek. 
A. fumosa sp. nov. (50 b). Forewing olive-brown with a darker striation; costal margin with 2 black fumosa. 
spots; the whole inner margin and the centre of the wing covered by a smoky violettish-brown cloud; a 
silvery white spot on the cross-vein, accompanied by small black scales. Towards the distal margin a few small 
glossy scales; fringes brown, at the indentations with white tips. Hindwing with a cloud occupying the basal 
half of the wing, the distal half being fawn-coloured speckled with black. Under surface red. clouded and 
speckled with black; costal margin of forewing yellow, before the concavity a streak of small glossy scales. 
Face and fore legs red; thorax and abdomen cloudy black; 1 <$ from the Angabunga R., Brit. New Guinea, 
at an altitude of 6000 ft., taken by A. S. Meek between November 1904 and February 1905. 
48. Genus: Orefa Whr. 
Proboscis and frenulum absent. Palpi very small, antennae pectinate in both sexes; middle and hind 
tibiae without spurs; legs fringed with hairs; forewing: apex produced to an obtuse point, distal margin curved. 
Hindwing with a rounded margin, the anal angle well marked. In the fore wing vein 6 rises from the upper 
cell-angle; 7 and 8 stalked from the angle, 9, 10, 11 stalked; 9 anastomoses for a short distance with 7, 
8 and forms an areola. Type: P. extensa Wkr. — The wings of this genus and of the allied genera are more 
densely clothed with hair-like scales than in the others to which they exhibit similar relations as the genus 
Striglina (cf. Vol. II, p. 273) and its group to the other Thyrididae. 
0. fulvata Warr. (50 e). Forewing dull yellowish with scanty reddish-yellow streaks along the basal fnlvata. 
half of the costa, before the apex and at the anal angle tinted with pink, lines dull yellowish-pink; inner 
line curved, and below the median distinct, distal line oblique to the apex before which it is sharply angular 
and bent back to the costal margin; cell-end spot angular, dull red with a dot of small white scales at the 
angle. In the hindwing the cross-vein is angular, with 3 white dots, followed by a rosy yellowish-red line 
terminating into a yellowish-red spot at the anal margin; traces of an inner yellowish-red line; marginal half 
of the wing coppery reddish-yellow with 2 or 3 rows of small dark spots between the veins; fringes pink. Under 
surface pale yellow, the oblique line of the forewing and a diffuse stripe along the submedian fold pink; marginal 
half of hindwing pink. Face, palpi, chest, and fore legs bright pink; thorax and abdomen yellow, tinted with 
pink. Described from a $ from the Key Is.; also 2 $9 from Kiriwina marked with brown instead of pink, as 
well as 1 9 from Woodlark I. 
0. unilinea Warr. (50 c). Forewing dull yellowish-red with a feeble lilac tint, the angular cross-vein unilinea. 
marked with small light scales forming dots at both ends. A yellowish-red. slightly curved line, outside bordered 
with light yellow, from the centre of the inner margin to the apex:; fringes brown. Hindwing with deep yellowish- 
red median and terminal shadows, costal-marginal area light. Under surface more yellow; the yellowish-red 
lines are finer and brighter; face and palpi of a bright scarlet; thorax and abdomen coloured like the wings. 
Shoulders flesh-coloured white. In this species the apex of the forewing is only slightly produced and obtusely 
pointed; distal margin slightly curved; forewing more oblong. Described from a $ from Roon I. (New Guinea).

0. cotltinua Warr. (50 f). Forewing brownish-ochreous, speckled with dark brown, costal margin continua. 
bright red; the whole upper surface glossy; cross-vein narrow silvery white with a white dot at the lower 
end, followed by a narrow yellowish-red spot; an oblique outer line being double above the centre extends 
from the centre of the inner margin into the apex and is filled with scales of a mother-of-pearl gloss; apical 
and marginal areas tinted with brown; at the distal margin between veins 1 and 4 there are three small silvery 
white triangles. Hindwing with' the brown antemedian line; cross-vein with 2 small white spots; at the apex 
a reddish spot. Under surface more yellow, more speckled; on the fore wing the costal-marginal and apical 
areas, fringes, and the upper half of the outer line are of a bright pink; in the hindwing only the apical
