122 X.—THE 
XANTHORHOEH OXYPTERA. 
(Xanthorhoe oxyptera, Huds., Sub. Ant. Islds. of N.Z. i., 67, pl. 
115235) 
(Plate XIII, fig. 50 ¢.) 
This very interesting species was discovered by Cap- 
tain Dorrien-Smith at the head of the northern arm of 
Carnley Harbour, Auckland Island, during the visit of 
the scientific expedition in November, 1907. 
The expansion of the wings is 1 inches. The head, thorax, 
and abdomen are brownish-ochreous, the last-named with two 
blackish spots on the back of each segment. The palpi are 
slender, nearly as long as the head, whitish-ochreous. The 
antennae are whitish-ochreous, with long black pectinations 
extending to the apex. The fore-wings are elongate, narrow, 
with the apex extremely acute and the tornus rounded, rather 
dark greyish-brown, very glossy, with the bases of the veins and 
a broad costal band pale brownish-ochreous; a small black discal 
dot. Hind-wings narrow, apex and tornus rounded, greyish- 
brown, very glossy, without markings except a few extremely 
minute blackish marginal dots. On the underside all the wings 
are whitish-ochreous, the costa of the forewing and the whole 
of the hind-wing darker; the basal portions of all the veins are 
strongly marked in blackish-brown. The cilia of all the wings 
are very pale-ochreous. 
XANTHORHOE MNESICHOLA., 
(Larentia mnesichola, Meyr., Trans. N.Z. Inst. xx., 56.) 
(Plate XIV., fig. 31 @, 32 9.) 
This very obscurely-marked species has occurred in 
the South Island on Mount Arthur, at elevations of from 
3,900 to 4,500 feet. 
The expansion of the wings is 1 inch. The fore-wings are 
pale brownish-ochreous, and rather glossy; there is a series of 
minute black dots at the base, a second series at about one-third, 
then a cloudy curved band, slightly darker than the rest of the 
wing, followed by a third series of minute black dots; a fourth 
series is situated on the subterminal area. The hind-wings are 
very pale brownish-ochreous. 
The perfect insect appears in January and February, 
and frequents sub-alpine serub. 
XANTHORHOE OCCULTA. 
Philpi,, Dranss N-“ow Inst. socxys, 24.6, DL. 
3:O:0.6 ly, 15)5)) 
(Plate XIV., fig. 14 @, 15 9.) 
(Xanthorhoe occulta, 
This dull bronzy-looking species, which was discovered 
by Mr. Philpott, has occurred on Mount Ruapehu, and on 
the Tararua Ranges in the North Island, and at Mount 
Arthur, Arthur’s Pass, Otira, Dunedin and Invercargill in 
the South Island. ‘It’ has also been found on Stewart 
Island. 
The expansion of the wings is about 1 inch. The fore-wings, 
which have the costa straight and the apex acute, especially in 
the female, are deep bronzy-ochreous-brown strongly tinged with 
reddish in the female; the basal area and median band are 
clouded with grey; the veins are faintly marked in purplish- 
grey and at each point where they enter and leave the median 
band there is a confluent dark brown and white dot. The hind- 
wings are pale ochreous, tinged with reddish in the female; 
there is a median series of grey dots on the veins. 

GHOMETRIDAE, 
This species varies considerably in size and slightly in 
the depth of the colouring. 
The perfect insect appears from October till February, 
and is attracted by light. In the North Island and 
northern portions of the South Island it seems to be a 
sub-alpine species, having been found in forest glades 
between 3,000 and 4,000 feet above the sea-level. In the 
extreme south it occurs in the lowlands. 
XANTHORHOE STINARIA. 
(Camptogramma stinaria, Gn., Ent. Mo. Mag. v., 92; Larentia 
stinaria, Meyr., Trans. N.Z. Inst. xvi., 78.) 
(PlatesXLy., fig. 13 4.) 
This very bright-looking species has occurred in the 
North Island at Waiouru and Puketiritiri (Napier), and in 
the South Island at Mount Grey, Christchurch, Mount 
Hutt, Otira, Dunedin, Queenstown, Lake Wanaka, and 
Otatara, near Invercargill. 
The expansion of the wings is barely 1 inch. The fore-wings 
are bright ochreous-brown; there is an oblique dark-edged white 
line running from the dorsum near the base towards the middle 
of the wing, and a very conspicuous, oblique, slightly waved 
dark-edged white line at about %; the space between these lines 
is often considerably darker and there is generally a series of 
faint subterminal dots and a distinct terminal shading. The 
hind-wings are ochreous, without markings, The female is paler 
and more uniform in colour than the male 
The perfect insect appears from November till Feb- 
ruary, and frequents tussock country, or grassy openings 
in scrubby forest. 
Genus 15—NOTOREAS, Meyr. 
Face and palpi roughly hairy. Antennae in ¢@ bipectinated. 
Thorax and femora rough-haired beneath. Fore-wings: areole 
double. Hind-wings normal. : 
(Plate C., fig. 48, fore-wing of Notoreas brephos.) 
This interesting endemic genus, of which we have no 
less than twenty-three species, comprises a number of gaily 
coloured little insects, chiefly inhabiting mountain regions. 
All the species are day-fliers, and most of them only appear 
during the hottest: sunshine. One species is confined to 
the North Island, eighteen to the South Island, and four 
are common to both islands. 
NOTOREAS SYNCLINALIS, 
(Notoreas synclinalis, Huds., Trans. N.Z. Inst. xxxv., 244, pl. 
xxx., 6; Meyr., Trans. Ent. Soc. Lond., 1905, 220.) 
(Plate XIV., fig. 33 4, 34 9.) 
This very interesting and remarkable-looking species 
was discovered by Mr. Philpott at Seaward Moss, near 
Invereargill. It has also oeeurred on the hills near Pre- 
servation Inlet, at an altitude of about 1,000 feet above the 
sea-level, at Wyndham, on Longwood Range, and on 
Stewart Island. 
The expansion of the wings is nearly 14 inches. The fore 
wings have the costa broadly bordered with dark greyish-black;
