P. sigmata Wkr. (= novae-zealandiae Wkr., variolaris Guen.) (75 d). Near copularis, larger (up to signala. 
60 mm). Forewing dark ochreous, dull white near the centre and at the distal margin. The blackish dark 
radial band contains a few white spots and extends through the centre of the wing. Irregular dark, light- 
centred spots near the veins and often forming 2 or 3 rows near the distal margin. Hindwing yellowish - 
brown. Larva long-stretched, up to 70 mm long, yellowish, dorsum and stigmata brown, head very hard, 
horny, dark brown, the 3 first segments with horn-shields, the others with horny tubercles on which there 
are bristles. Very lively when being disturbed. It usually emits a quantity of black sap from its mouth 
and bites at the same time so as to frighten its enemies. It lives on the roots of grass. Imago in January 
till March, often common on the light. New Zealand, northern island (Napier, Palmerston, Wellington). 
P. antipoda H.-Schdjf. (77 b). Thorax and forewing greyish-brown. A square spot in the cell. Behind antipoda. 
it three rows of irregular blackish spots. Besides 2 submarginal rows of smaller paler spots. Abdomen and hind¬ 
wing somewhat darker brown. Postmedian rows of dark spots. $ 62 mm. New Zealand. 
P. fuscomaculata Wkr. (76 e). With this common and widely distributed species we begin the series fuscomacu- 
of Porina from Australia Proper. ^$ 65—73 mm. Of a transparent dull brown colour, forewing mixed more lata - 
or less with a lighter colour, with rows of brown transverse stripes and marginal spots. $ with long, strongly 
pectinated antennae. The form pardalinus Wkr., from South Australia (and Tasmania), is more brownish ochre- pardalinus. 
ous, especially on the abdomen and the margins of the wings. With 4 oblique bands of irregular square dark 
brown spiots which are dusted somewhat ash-grey. Marginal spots dark brown. Victoria, South Australia, 
Tasmania. — The species Oxyc. sordidus mentioned by Herrich-Schaffer in “AuBereuropaische Sclimetter- 
linge” may belong to this place here. But nothing can be said about it, as it is not even sure that Australia 
is its patria. 
P. aedesima Trnr. Thorax dark brown, abdomen lighter, reddish at the base. Forewing brown, densely aedesima. 
covered with whitish ochreous hair-like scales. Costal streak blackish-brown. Obliquely distad is an oblong 
white antemedian discal streak, finely edged with blackish. Besides 3 oblique lines of blackish-brown spots, 
sometimes white-centred, variably developed. The first from the middle of the costal margin, excurved 
around the discal spot, then straight to 2 / 5 of the inner margin. The second from % of the costal margin 
to 3 / 5 of the inner margin, almost straight. The third from 7 / 8 of the costal margin to the anal angle, also al¬ 
most straight. Sometimes another incompletely developed line near the base. Hindwing pale brown, red¬ 
dish or quite pale reddish at the base. 65 mm. North Queensland. 
P. beltista Trnr. Somewhat similar to rufescens (76 e). Thorax dark brown, abdomen more reddish, beltista. 
Costal margin of forewing strongly bent before the apex, apex pointed. Brownish ochreous, darker at the 
base. Costal margin dark brown as far as % of its length. A round faded light brown spot below the cell at 
Y 3 of the length of the wing. A series of faded similar spots from % of the costal margin to the centre of 
the inner margin, and a similar row before the margin, the latter with dark centres. A few scattered dark 
spots behind them and very light spots close before the margin. Hindwing drill reddish, more intensely red 
at the base. Somewhat brownish ochreous at the apex. <$ 100 mm. Queensland. 
P. australis Wkr. (= Pielus maculosus Fldr.) (77 b). <$ 68—84 mm. Head and thorax dark brown. An- australis. 
tennae with shorter pectinations. Fore wing brownish ochreous, numerous irregular small silvery white spots 
in black rings, in front larger and irregular, behind in three transverse rows. Hindwing ochreous, with a dark 
brown tinge. Tasmania. 
P. faseiculata Wkr. $ brownish yellow, ash-grey. Abdomen ash-grey. Forewing ochreous, pointed, fasciculata. 
with a white, black-edged longitudinal stripe near the basal part of the inner margin. Hindwing brownish 
ash-grey, slightly transparent. Length of body 17—18 mm, wings 35 mm. Australia. 
P. dirempta Wkr. (76 d). Thorax blackish-brown, abdomen yellowish ochreous. Forewing dark brown, dirempta. 
brownish ochreous in the disc in front. Costal margin narrowly blackish. A whitish radial stripe from the 
base through the centre, broadly faded brownish-white in the distal part as far as the anal angle. Two 
small triangular silvery white, dark-edged spots at the upper margin of the band before the centre. Two 
or three similar rows of spots are marked in the exterior part at the costal margin. Hindwing ochreous. 
cj 68 mm. South Australia. 
P. determinata Wkr. <$ 58 mm. Head, thorax rather dark brownish ochreous. Antennae as in austra- determina- 
lis (77 b). Forewing ochreous blackish-brown, with different indistinct continuous rows of somewhat faded dark in 
dots; an oblique silvery white transverse macula, apparently composed of 3 spots, in the midst of the disc, 
bordered on both sides by a darker brown colour. Hindwing brownish ochreous. West Australia (?) ac¬ 
cording to Meyrick. 
P. rufescens Wkr. (76 e). Thorax very dark brown, abdomen reddish at the base. Forewing dark rufescens. 
brown with 2 or 3 blackish-brown spots in the centre of the wing in front and two rows of spots behind, 
all of them edged with brownish ochre. Besides 2 silvery white, dark-edged spots in the centre of the wing. 
Hind wing dull brownish ochreous, reddish at the base. Very variable. The 4 specimens in the Coll. Pfitzner, 
from the mountains to the north of Melbourne, exhibit a much lighter brown of the forewing broadly inter¬ 
mixed with whitish ochre, especially at the distal margin, and bright reddish ochreous hindwings. The two 
silvery dots lying together in the centre of the disc of the forewing, mentioned by Meyrick in the Tas-
