P. periculosa Warr. (13 c). Ground-colour as in vagabunda, hindwing more angled, lines slighter, differ¬ 
ently shaped, cell-marks red, complex, fringes pale buff. British and Dutch New Guinea. 
P. florediscata Warr. (4 i) may be known at a glance by the very large, irregularly shaped central 
marks, that of the hindwing bright red. Owen Stanley Bunge, Mount Goliath and Weyland Mountains. 
P. caniola Warr. ( = phaeostigma Turn.) (4h as carniola). Rather thinly scaled, somewhat as in peri¬ 
culosa. Larger and more bluish, with the fringes concolorous, the cell-marks less red, differently shaped, containing 
proximally and distally a black dot or spot. British and Dutch New Guinea and N. Queensland. 
P. geometrica Trout is similarly coloured to caniola (4 h), but much smaller, the hindwing less angled, 
the black markings increased, forming 3 (not 2) marks on the cell-mark (the distal one angular), sharp ter¬ 
minal dots between the veins and some dusting on the lines. Mount Goliath, only the type known. 
P. signifera Warr., from the Owen Stanley Range, has the cell-marks reddish, mixed with black and 
surrounded with white. — In superba Prout (4 h) that of the hindwing is enlarged and almost devoid of black 
admixture. Mt. Goliath and the Snow Mountains. 
P. in tut bid a Prout. Probably related to tripuncta (4 h), agreeing in having the palpus short, almost as 
in a Chlorocoma. Subtranslucent whitish green, closely irrorated with blue-green; cell-dots black, lines diffuse, 
greenish, lunulate-dentate, weakly pale-edged on their reverse sides; hindwing crenulate, with a stronger tooth 
at the 3rd radial. Expanse 26 mm. Weyland Mountains, 1 $. 
P. tripuncta Prout (4 h) is slightly more translucent than is suggested by our figure and the post¬ 
median line not quite so strong, blackest on the veins. Named from the presence, in addition to the two 
cell-dots, of a blackish dot on the median vein of the forewing, midway between base and discocellulars. 
Mount Goliath. 
P. bipuncta Prout. Still paler (whitish green, with some blue-green irroration), the additional dot 
absent, the postmedian line more proximally placed, the distal margin with minute black vein-dots. Mount 
Goliath. 
P. seminivea Warr. (13 c). Not translucent; white, dotted and spotted with deep green and with the 
green lines broader than in the two preceding. Angabunga River, British New Guinea. — respersa Prout, 
from Mount Goliath, is rather larger, the green scaling more uniformly sprinkled, except in the median area 
of the forewing posteriorly, where the white spot remains tolerably conspicuous. 
P. albiseriata Warr. (4 f) is generally smaller than seminivea and has the green and white parts 
more sharply differentiated, especially near the distal margin, where a definite though irregular row of white 
spots is formed, and on the hindwing, where a green basal area is succeeded by a white central band. 
Owen Stanley Range and Mount Goliath. 
P. scintillans Warr. Size, shape and colouring nearly as in seminivea (13 c) but with the white very 
much reduced, appearing only in scattered dots and spots, the largest being near the tornus of the forewing. 
Angabunga River. — isorrhopia Prout (4 f) is rather larger, the white dots of the cell-fold and distal area 
better developed. Mount Goliath. 
P. nictata Prout differs from scintillans in having the white dots minute (chiefly subterminal and 
on the forewing antemedian), only the hindmost subterminal of the forewing somewhat enlarged, the cell-dots 
black, surrounded on the forewing by glittering whitish scales, on both wings by a small area of purplish- 
grey suffusion. Mount Goliath. 
P. iosticta Meyr. Larger than nictata (31—38 mm), the white markings similar, the outer row of 
dots running obliquely inward to R 2 , excurved between this and the fold, the enlarged hindmarginal one 
edged with red proximally and distally. New South Wales (loc. typ.) and Queensland. 
P. nivisparsa Btlr. (= triseriata Warr.) (13 c). Widely distributed and scarcely at all subject to varia¬ 
tion. Nearest to isorrhopia (4 f) but without the white apical spot and tornal patch of the forewing, the 
white lines and rows of dots very regular in development throughout . Distributed from Buru and Obi to the 
Bismarck Archipelago; Butler’s type was from Duke of York Island. 
P. debilis Prout (4 f) is one of the already-mentioned transitions to Gelasma; placed here on account 
of the shape, scaling and long $ palpus. Excepting the following (q. v.), I know of no species with which 
it is likely to be confused. Mount Goliath. 
P. fragilis Warr. (4 f). Rather smaller than debilis, the distal margin of the hindwing more bent in the 
middle (not shown in our figure), the cell-dots less dark, in the typical race edged distally with whitish, the 
postmedian row of dots fainter, less excurved; forewing beneath with a bright green median shade, which
