whilst resting on the underside of the fronds. In this re- 
spect it closely resembles Selidosema aristarcha, both species 
having evidently acquired a similar wing pattern for the 
same protective purpose. 
TORTRIX ORTHOCOPA. 
(Tortrix orthocopa, Meyr., Trans. N.Z. Inst., lv., 661.) 
(Plate XXIV ,, fiz, 1 s:) 
This very distinetly-marked species has occurred at 
Kaeo, north of Auckland, Swanson, Waimarino, and Well- 
ington, but appears to be very rare. 
The expansion of the wings is about % inch. The fore-wings 
are light brown, sometimes slightly tinged with purplish-grey on 
the costa and termen; there is an oblique basal patch; a very 
broad, oblique, central band extending from a little before the 
middle of the costa to the tornus and a V-shaped mark on the 
costa before the apex; all these markings are narrowly edged 
with dark brown and clouded with purplish-grey. The hind-wings 
are very pale brownish-ochreous with a few very obscure greyish 
spots. 
The perfect insect appears from January till March, 
and frequents forest. 
TORTRIX TIGRIS. 
(Tortriz tigris, Philp., Trans. N.Z. Inst., xlvi., 120.) 
(Plate XLYV., fig. 19 @.) 
This rather striking species was discovered by Mr. 
Philpott at Tisbury near Invereargill. It has also occurred 
at Kaeo, north of Auckland, Swanson, Wellington, and on 
Stewart Island. 
The expansion of the wings is { inch. The fore-wings are 
pale ochreous-brown traversed by three broad, very oblique, wavy 
brown transverse lines; the first covers the whole of the basal 
area and extends beyond 4 on the dorsum; between this and the 
second band there is a double fine, wavy transverse line; the 
second band covers the whole of the median area and has a large 
patch of pale ochreous-brown in the middle; between the middle 
and the apical bands there is a fine, wavy transverse line; the 
apical band is elongate-triangular, its base resting on the costa 
immediately before the tip of the wing and its apex touching the 
termen above the tornus. The hind-wings are pale ochreous 
spotted with pale grey. 
Although somewhat resembling Tortrx torogramma 
and 7’. orthocopa this species is quite distinct from either. 
It is larger and paler and the fine wavy transverse lines, 
‘between the broad bands, are not present in either of those 
species. 
The perfect insect appears in January, and frequents 
tree-ferns (Dicksonia). It is a very rare species. 
TORTRIX CONDITANA. 
(Tortrix conditana, Walk., Cat. xxviii., 306; Cacoecia enoplana, 
Meyr., Trans. N.Z. Inst., xv., 49; Cacoecia astrologana, 
Meyr., Trans. N.Z. Inst. xxi., 156.) 
(Plate XXIV., figs. 42-44 varieties.) 
This species has occurred at Ohakune, Wellington, 
Otira Gorge, Dunedin, Lake Wakatipu and Invercargill. 
TORTRICIDAE., 229 
The expansion of the wings is slightly under 1 inch. The 
fore-wings have the costa moderately arched, the apex acute and 
the termen strongly rounded, bright ochreous with reddish-brown 
markings; there is usually a large, irregular, oval spot touching 
the costa a little before the middle and a broad triangular mark 
on the costa beyond the middle with a narrow stripe of the 
ground colour between them; there are usually two rather large 
dots on the disc near the termen, an irregular row of sub-terminal 
dots and frequently a few scattered dots on the other portions 
of the wing. The hind-wings are white with a few faint grey 
spots and a series of black terminal dots on the basal portion of 
the cilia. 
There is considerable variation; the large reddish- 
brown costal spots are sometimes absent, their place being 
taken by an obscure, short, reddish-brown longitudinal line 
near the middle of the wing, the wing itself being often 
thickly studded with black dots: other forms have the 
fore-wings strongly clouded with bright brownish-ochreous 
throughout and the reddish-brown markings very faintly 
indicated. 
The perfect insect appears from October till March, 
and is occasionally taken in the middle of winter. It 
usually frequents gardens and other cultivated places, and 
sometimes enters houses, but is never plentiful. 
TORTRIX SPATIOSA. 
(Tortriz spatiosa, Philp., Trans. N.Z. Inst., liv., 150.) 
(Plate XLIX., fig. 5 9.) 
This species has oecurred at Ohakune in the North 
Island and on the Dun Mountain near Nelson, in the 
South Island. 
The expansion of the wings is almost 14 inches. The fore- 
wings have the costa strongly arched, the apex acute and the 
termen strongly bent outwards before the tornus; pale brownish- 
ochreous, covered with fine darker strigulae; a broad oblique, 
slightly waved, paler dark edged transverse band from about +} 
of costa to middle of dorsum and « very conspicuous deep brown 
triangular mark on costa before apex. The hind-wings are cream 
coloured tinged with yellow near the apex, where the cilia are 
brown. In the single male specimen in my collection the fore- 
wings are strongly suffused with dark brown. 
The perfect insect appears in January, and is found 
in forest. 
TORTRIX SYNTONA. 
(Cacoecia syntona, Meyr., Subantarctic Islands of N.Z., i., 73.) 
(Plate XXIV., fig. 46 9.) 
This interesting species was discovered at Auckland 
Island, during the scientific expedition of November, 1907. 
The expansion of the wings is about 1 inch. The fore-wings 
are elongate with the apex somewhat produced and the termen 
obliquely rounded; ochreous with brown markings; there is a 
moderately broad, straight longitudinal streak from the apez, 
almost reaching the base; a few indistinct marks on the termen 
and two more or less distinct dots in the dise before the middle. 
The hind-wings are whitish-ochreous with an obscure grey streak 
along the posterior part of the median fold and another streak 
beneath vein 2.
