9. Genus: Ortliorisma Prout. 
Probably related to Epipristis but with long terminal joint to the palpus, especially in the $, broader 
forewing, its distal margin anteriorly scarcely at all oblique, generally stronger abdominal crests and some 
slight differences in the venation. The frons is not — as in Neobalbis, Terpna and other allies — protuberant, 
the femora less hairy, the hindtibia of the not dilated. Only one species is known. 
0. netunaria Guen. (= crassistriga Warr., unicolor Warr.) (8a). Not likely to be confused with any netunuria. 
other species. The design of the underside bears some resemblance to that of A. musicoloraria , but the dark 
border of the forewing is still broader, almost straight-edged proximally, its proximal part almost black, its 
distal and broader part reddish grey, reaching the termen. Known from the Philippines, Borneo, the Natuna 
Islands and Perak; Guenee’s type was from Borneo. 
10. Genus: Epipristis Meyr. 
An offshoot of Pingasa, consisting of a few species, generally of smaller size, but characterized chiefly 
by their scarcely hairy pectus, smooth femora, short approximation of the costal vein of hindwing to the cell 
and non-pectinate <$ antenna. Confined to the Indo-Australian Region. 
E. mininiaria Guen. (— parvula Walk., truncataria Walk.) (8a) is the smallest species, whitish with minimaria. 
grey irroration, scarcely tinged with green, the lines slender, the spots outside the postmedian predominantly 
light reddish. Both wings beneath broadly dark-bordered almost to the distal margin. Described from Ceylon. 
Common in N. India and reaching Lower Burma. Doherty brought two specimens from S. Celebes, which 
may represent a race. 
E. nelearia Guen. (8 a). Less small than minimaria , the lines stronger, the postmedian with sharper teeth, nelearia. 
the spots outside it clouded with dark grey. The dark bands beneath, especially that of the hindwing, do 
not reach the distal margin. Described from Borneo, but reaching N. India in one direction and the Moluccas 
in the other. — oxycyma Meyr., hitherto referred to minimaria, is evidently, according to a good series from oxycyma. 
N. Queensland in the Tring Museum, a more whitish race of nelearia. 
E. rufilunata Warr. (5 e) is still larger, at least in the $, and may be likened to a giant, strongly- rufilunata, 
marked green minimaria , with rather broader hindwing, the proximal edge of its border beneath more curved. 
Only known from- Warren’s two originals, from Upper Aroa River, British New Guinea. — viridans Prout, viridans. 
erroneously described as a race of nelearia, is probably the <$ to rufilunata or a slight geographical modification 
from a lower altitude. Except for its much smaller size and less strong markings, it differs little from the 
Founded on two GS from Lower Aroa River. — antelucana subsp. nov. Cell-dots larger, above and beneath; antelucana. 
upperside rather deeper green, with the spots outside the postmedian line rather stronger; underside suffused 
with dusky grey, the dark borders blackened. New Hanover, April 1923, a pah in Mus. Tring. 
11. Genus: Eingasa Moore. 
A moderately large genus, easily recognizable by its shape, scheme of markings, whitish or pale green 
ground-colour and especially by the tufts of raised scales at the end of the short cell of the hindwing. Antenna 
of $ shortly pectinate, of $ simple. The underside, unless otherwise stated, is white, at base generally 
yellow, with broad black borders, which enclose white spots at apex and midtermen. The species are chiefly 
Indo-Australian and African, but 3 enter the Palaearctic Region (sec Vol. 4). 
P. angulifera Warr. (G = atriscripta Warr., munita T. P. Luc.) (5 e). The brightest green Pingasa angulifera. 
and showing rather strong sexual dimorphism. The $, on which Warren founded the species, is generally 
larger than the $ and has a very broad red band outside the post median line. Distributed in New Guinea, 
the D’Entrecasteaux (from which both the types were described) and the Bismarcks. 
P. meeki Warr. (4 b). Closely related to angulifera and with similar dimorphism. Slightly larger and mecki. 
paler, the cell-dot reddish, not black, the median area a little broader, the postmedian line of the forewing right- 
angled at the 1st radial. Described from Biagi, Owen Stanley Range, since found in a few of the mountains 
of Dutch New Guinea.
