X.—THE 
The expansion of the wings is 1$ inches. All the wings 
are pale ochreous. The fore-wings have a black discal dot; the 
median band is clouded with grey and its edges clearly indicated 
by fine wavy blackish lines; there is a cloudy blackish patch 
below the apex. Both wings have a terminal series of double 
dots. On the underside the fore-wings are deeply clouded with 
grey, except on the costa and apex, and the hind-wings have two 
very conspicuous broad, white-edged, brown streaks; the first 
across the middle of the wing from the base to the middle of 
the termen, the second along the dorsum. 
The perfect insect appears in December, and is found 
on open hill tops. 
XANTHORHOE EXORIENS. 
(Larentia exoriens, Prout., Proc. N.Z. Inst. xliv., 54.) 
(Plate XIV., fig. 8 @.) 
This species was discovered by Mr. Howes at Glen- 
orchy, Lake Wakatipu. It has also occurred at Nevis, 
Central Otago. 
The expansion of the wings is 14 inches. All the wings are 
ochreous, the fore-wings being strongly tinged with reddish on 
the costa and extreme base; the median band consists of four 
very irregular faint blackish lines, the second and third lines 
forming three distinct loops; there is a distinct blackish discal 
dot and the outer edge of the median band is very strongly 
waved, with distinct projections above and below: the middle; 
the subterminal area is broad with one or two very faint cloudy 
marks; all the wings have a terminal series of minute brown 
marks, and all the cilia are plain ochreous without bars. The 
underside of the hind-wings is dull reddish-ochreous, without 
distinct markings. 
The perfect insect appears in March, and frequents 
open grassy country. 
XANTHORHOE IMPERFECTA. 
(Xanthorhoe imperfecta, Philp., Trans. N.Z. Inst. xxxvii., 330, 
ak vec, Ai) 
(Plate XIV.) 1legselGaea) 
This very distinct species was discovered by Mr. Phil- 
pott at West’ Plains, near Invercargill. It has also 
occurred at Dunedin. 
The expansion of the wings is about 14 inches. All the 
wings are bright ochreous. The fore-wings are tinged with red- 
dish towards the apex and clouded with darker ochreous on the 
terminal area; there are several brown bars on the costa each 
usually followed by a whitish mark; in the female these bars 
are very faintly produced across the wing as transverse lines; 
there is a brownish discal dot. The cilia are ochreous barred 
with blackish. 
The perfect insect appears in December and January, 
and frequents low-lying swampy forest. It is a rare and 
local species. 
I am indebted to Mr. Philpott for specimens. 
XANTHORHOE ORARIA. 
(Xanthorhoe oraria, Philp., Trans. N.Z. Inst. 
xXxxii., 6.) 
(Plate XIV., fig. 30 @.) 
Xxxv., 248, pl. 
This very plain-looking species was discovered by Mr. 
Philpott at New River, near Invereargill. It has also been 
TFEOMETRIDAE. 
121 
found on Ben Lomond and Mount Earnslaw, Lake Waka- 
tipu, at elevations of about 4,000 feet above the sea-level, 
as well as on Stewart Island. 
The expansion of the wings of the male is slightly over 1 
inch. All the wings are pale ochreous, the fore-wings being 
usually a little darker and occasionally very faintly tinged with 
dull greenish; there is a distinct blackish discal dot and the 
edges of the median band are rarely indicated by obscure wavy 
greyish transverse lines. 
The female is unknown at present, and may possibly be 
semiapterous. 
According to Mr. Philpott specimens from Ben Lomond 
are longer-winged than the coastal form, and those from 
Mount Earnslaw are still longer. 
The perfect’ insect appears from November till April, 
occurring plentifully amongst tussock grass on sand-hills. 
Described and figured from specimens kindly given to 
me by Mr. Philpott. 
XANTHORHOE SERICODES, 
(Xanthorhoe sericodes, Meyr., Trans. N.Z. Inst. xlvii:, 202.) 
(PlateexaivV.,. te. 20) 4) 
This species, which is very closely allied to Xanthorhoe 
oraria, was discovered on the lower slopes of Mount Earns- 
law, Lake Wakatipu, at an elevation of about 3,500 feet 
above the sea-level. 
The expansion of the wings of the male is about 14 inches 
The fore-wings are very glossy, dull ochreous tinged with brown- 
ish; there is a blackish discal dot and faint traces of a wavy 
transverse line at about %; a cloudy greyish spot is sometimes 
situated at the apex. The hind-wings are uniform dull ochreous. 
The female is unknown at present, and may perhaps 
be semi-apterous. 
The perfect insect appears in January, and frequents 
tussock openings amongst sub-alpine serub. 
XANTHORHOH NEPHELIAS. 
(Larentia nephelias, Meyr., Trans. N.Z. Inst. xvi., 78; Xanthorhoe 
subflava, Howes, ib., xlix., 274.) 
(Plate XIV., fig. 45 @.) 
This large and very distinet species has occurred at 
Arthur’s Pass. 
The expansion of the wings is about 14 inches. The fore- 
wings are very pale whitish-ochreous darker on the costa where 
there are no grey markings; the basal area as far as the outer 
edge of the median band is clouded and speckled with very pale 
grey, the first and second lines being slightly darker; there is 
a broad wavy whitish-ochreous subterminal band and a grey 
terminal band, often composed of a double series of confluent 
spots. The hind-wings are pale ochreous with a terminal series 
of elongate pale grey spots. The cilia are whitish-ochreous 
faintly barred with grey. 
The perfect insect appears in February. It frequents 
open tussock country above the limits of ordinary forest, 
sometimes attaining an elevation of 4,600 feet above the 
sea-level,
