X.—THE 
discal dot; beyond this there is a more or less distinct wavy 
band of pale grey or brown, and one or two obscure wavy black- 
ish lines near the termen. The hind-wings are bright orange, 
dotted with grey near the base and dorsum, with from two to 
four more or less distinet wavy black transverse lines, generally 
rather narrow; the termen is moderately broadly bordered with 
black. 
This insect is rather variable; the ground colour of 
the fore-wings is often more or less suffused with brown, 
and the spaces immediately before and beyond the median 
band are occasionally clouded with brown. or deep orange; 
the terminal band of the hind-wings also varies in width. 
A small form, often met with on mountains or in river 
beds, has the fore-wings almost blue with the transverse 
lines rather indistinct and the hind-wings very bright 
orange with very narrow black markings. This form was 
long regarded as a distinct’ species under the name of 
Notoreas zopyra. 
The egg, which is laid on its side, is about one-fiftieth 
of an inch long, oval, depressed on upper surface, bright 
orange-brown, covered with fine hexagonal depressions. 
The perfect insect appears from December to March. 
It is very active, and is extremely fond of settling on roads 
or bare ground in the hot sunshine, darting away on the 
approach of an enemy. It is very common on the moun- 
tains, and is often found at elevations of from 3,000 to 
4,000 feet above the sea-level. 
NOTOREAS VULCANICA. 
(Pasithea vuleanica, Meyr., Trans. N.Z. Inst. xvi., 89; Notoreas 
vulcanica, ib. xvili., 184.) 
(Plate XV., fig. 35 @.) 
This very dark richly-coloured species has occurred at 
Waimarino, Waiouru, on the lower slopes of Mount Rua- 
pehu, and at Makotuku, and the Kaweka Range, in the 
Hawke’s Bay District. In the South Island it has occurred 
at Macetown. 
The expansion of the wings is fully 1 inch. The fore-wings 
are rich brownish-black with speckled grey markings; the edge 
of the basal patch and the inner margin of the median band are 
bounded by jagged grey lines; the median band is broad, very 
dark, with an irregular speckled grey centre, containing a con- 
spicuous black discal dot; the subterminal area is mottled with 
deep brown and traversed by an irregular broken grey sub- 
terminal line, The hind-wings are bright orange; there is a 
very large blackish-brown basal patch, followed by an extremely 
broad band, then one or two variable transverse lines and a very 
broad terminal band. The cilia of all the wings are brownish- 
black with indistinct paler bars. 
The perfect insect appears from January till March, 
frequenting dry stony places and flying rapidly in hot 
sunshine. It seems to be extremely local. 
NOTOREAS OMICHLIAS.

(Plate XIV., fig. 41 @.) 
Notoreas 
This very dull-looking, obscurely-marked species, has 
occurred on the Tararua Ranges in the North Island, and 
GEOMETRIDAE. 127 
on the Mount Arthur Tableland, the mountains around 
Castle Hill and Lake Wakatipu, and the Hunter Moun- 
tains in the South Island. 
The expansion of the wings is about 1 inch. The fore-wings 
are dark grey in the male, paler grey in the female more or 
less sprinkled with whitish scales; there are three rather broad 
speckled brown wavy transverse lines and a faint sub-marginal 
shading. The hind-wings are brownish-grey, paler in the female. 
Considerable variation exists in the distinetness of the 
transverse lines, which are often bordered with black and 
white scales; a discal dot is usually, although not invari- 
ably, present on the fore-wings. Specimens from the 
Hunter Mountains are paler and greyer than the usual 
form with much more distinct brown markings. 
This species has a superficial resemblance to a very 
dark specimen of Xanthorhoe semisignata, but the num- 
erous fine transverse lines, which are always present in 
that species, will at once serve to distinguish it. 
The perfect insect appears in January and February, 
and frequents open rocky country on high mountains, at 
about 5,000 feet above the sea-level. It is extremely 
abundant on the Tararua Range, near Wellington, and 
apparently is specially characteristic of mountains in the 
North Island. 
NOTOREAS FULVA. 
(Lythria fulva, Huds., Trans. N.Z. Inst. xxxvii., 357, pl. xxii., 3.) 
(Plate XV., fig. 7 @.) 
This very distinct species was discovered by Mr. J. 
H. Lewis near Mount Ida, Central Otago, at’ about 3,500 
feet above the sea-level. It has also oceurred at Alexandra. 
The expansion of the wings is ? inch. The fore-wings are 
pale greyish-brown, with blackish markings; there is a wavy 
darker band near the base; a broad median band with a strong 
rounded projection towards termen near the middle, the centre 
of the median band is paler, and often’ clouded with reddish- 
ochreous; it contains a distinct blackish discal dot; there is a 
wavy subterminal line interrupted by a series of blackish marks 
on the veins and a dull reddish-ochreous terminal band; the 
cilia are grey with blackish bars. The hind-wings are! dull 
reddish-ochreous. There are three very obscure blackish trans- 
verse lines. The cilia are grey, faintly barred with darker. 
This species varies considerably in the depth of the 
general colouring, and in the intensity of the markings. 
Some of the females are very pale, and have the fore-wings 
much suffused with reddish-ochreous. 
The perfect insect appears in March.

Island; nine to the South Island, and one common to both 
islands.
