P. indistincta Warr. (4h). Recognizable by the shape, the dark colour and the obsolescense of the 
lines. Terminal joint of palpus less elongate than in the 4 preceding species. British and Dutch New Guinea. 
P. obsoleta Warr. Blue-green, less dark than in the preceding group, with the costal edge of the fore- 
wing more broadly cream-buff, the fringes also lighter and cleaner cream-buff than in vestigiata ; lines as faint 
as in indistincta, cell-spots more so. The name-typical form, from Angabunga River (Owen Stanley Range) 
is very broad-winged, the distal margin of the forewings very straight. — subobsoleta Prout (4 g) is slightly 
less broad-winged, the colour a little less bluish green, the lines and on the forewing the cell-dot a little bet¬ 
ter expressed. Possibly a separate species. Mount Goliath. 
P. infirma Prout, founded on a single $ from Mount Goliath, is smaller (34 mm), not quite so bluish 
as in obsoleta, more irrorated with white, the lines formed of white dots or dashes on the veins, the postmedian 
of the hindwing nearer to the distal margin than to the cell; terminal dots wanting; fringes green, tipped with 
white. 
P. delicata Warr. (13 b) likewise has the postmedian line more or less punctiform, but is very different 
from infirma in having this line more proximally placed, as well as in its smoother green colouring, clean 
buff costal edge and fringes, more oblique distal margin of forewing and more produced anal angle of hind¬ 
wing; black terminal dots present, though sometimes minute. Snow Mountains (type), Owen Stanley Range, 
Hvdrographer Mountains and Mount Rossel (Rossel Island). 
P. dentatilineata Prout (4g as dentilineata). Nearest to punctulata, but with the face green, the white 
lines broader. The $$, on which the species was founded, are further distinguishable by having the cell-dots green, 
not blackish, and the terminal dots minute or absent, but a form which I suppose to be dentatilineata ^resembles 
punctulata in both these respects. Mount Goliath, also from the Aifak and Wandammen Mountains. 
P. tryphera Prout (12 h) is another green-faced relative of punctulata, rather small, with the pale lines 
almost obsolete, the cell-dot and terminal dots black, but minute; fringes whitish; the buff costal edge of the 
fore wing is mixed with grey. Mount Kunupi, Weyland Mountains. 
P. punctulata Warr. (4g). Pace red, not (as in all the preceding species of the group) green. Palpus 
of $ very long. British and Dutch New Guinea. — leucogramma Prout, from Ceram and subsequently from 
Buru, differs chiefly in the presence of a conspicuous white dorsal line on the abdomen. Of both races, the 
$ is locally abundant, the $ extraordinarily scarce. 
P. glauca Warr. differs from delicata (13 b) in its rather duller green colouring (though much brighter 
than in the vestigiata group) and in having the lines composed of white spots on the veins, the ones on the 
2nd submedian, especially of the forewing, strongly enlarged. Biagi (type), Mount Goliath and 
Wandammen Mountains. 
P. philocala Prout. 31 mm. Coloration about as in coerulea (4 g), abdomen with a white dorsal line as in 
leucogramma ; lines formed of white vein-spots, differing from those of glauca in that the central ones (on base 
of M 2 and on middle of R 3 respectively) are as large as, or larger than, those on SM 2 . Mount Kunupi, Wey¬ 
land Mountains. 
P. caeruleotincta Prout. 27 mm. Blue, only in a little more greenish than in the genus Derxena. Face 
olive-fuscous. Forewing broad, with the cell-spot large, black, the lines formed of black-grey (not white) spots 
on the veins. Only the type known, collected by A. F. R. Wollaston on the Mimika River, Dutch New 
Guinea. A very distinct species. 
P. coerulea Warr. (4g). Face red above, green below, becoming whitish at lower edge. This species 
and the following are distinguishable at a glance from all the others by the maculation of the abdomen; in 
coerulea the bright ochreous spot on the anterior part of the 2nd tergite is large. British and Dutch New 
Guinea; also Ceram and Buru. 
P. punctifimbria Warr. Close to coerulea (4g), but of a yellower green, the green part of the face 
not becoming whitish below, the ochreous part of the spot on the 2nd tergite smaller, the fringe dotted with 
black-brown at the vein-ends. Upper Aroa River and Hydrographer Mountains, British New Guinea. 
P. phoenicogramma Prout. A small species (22 mm), of a paler green colour than the preceding 
group, with somewhat shorter palpus, and very distinct in having the cell-dots and the lines (including a 
terminal one) reddish ; postmedian on the forewing nearly parallel with distal margin, a little farther therefrom 
than from the cell-dot, on the hindwing very near the cell-dot, slightly bent outward at the base of the 3rd 
radial. Forewing beneath suffused with reddish except posteriorly. Mount Goliath, only the type ^ known. 
P. (?) phyllosa Pagenst. is unknown to me, but seems more likely to be a Prasinocyma than an 
Oenospila, as was formerly supposed. “22 mm.” Bright sap-green, with dark cell-dot and ill-developed red
