XV.—THE TORTRICIDAE. 227 nih 
The expansion of the wings is about ~ inch. The fore-wings 
are rather elongate triangular; pale dull reddish-brown with the 
veins very faintly marked in lighter brown; there is an elongate 
pale greyish discal dot and the basal and discal portions of the 
wing are slightly clouded with ochreous. The hind-wings are 
greyish-ochreous. 
The perfect insect appears in February and March and 
frequents open country or serub. It seems to be a very 
rare and local species. 
TORTRIX INDIGESTANA. 
(Tortrix indigestana, Meyr., Proe. Linn. Soe. N.S.W. 1881, 520.) 
(Plate XXVL., fig. 8.) 
This delicate-looking little species has occurred at 
Whangarei, Waimarino, Mount Ruapehu (4,000 ft.), at 
Makara Beach near Wellington and at Waitati near Dune- 
din. 
The expansion of the wings is slightly over 4 inch. The 
fore-wings are elongate-oblong with the termen obliquely 
rounded; pale grey very densely speckled with darker grey; there 
are four more or less distinct discal dots; one near the base, two 
near the middle and one on the termen. The hind-wings are 
pale brownish-grey. 
The larva feeds on Pimelea prostrata in October and 
November. 
The perfect insect appears from October till December. 
It is found in the neighbourhood of its foodplant, but seems 
to be confined to very restricted spots. 
Described and figured from specimens bred by Mr. R. 
M. Sunley. 
Mr. Meyrick states that this species is common in Aus- 
tralia, where the larva feeds on Hitbbertia linearis, and 
very likely also on other plants. 
TORTRIX ARGENTOSA. 
(Tortrix argentosa, Philp., Trans. N.Z. Inst., lv., 209.) 
This species was discovered by Mr. Philpott on the 
Dun Mountain near Nelson, at about 3,000 feet above sea- 
level. 
Like Tortrix indigestana, from which it differs in the whiter 
ground colour and absence of black speckling. 
The perfect insect appears in December and flies in the 
evening amongst low shrubs and herbage. 
TORTRIX SUBDOLA. 
(Tortrix subdola, Philp., Trans. N.Z. Inst., lv., 212.) 
This species, which is very similar to Tortrix indiges- 
tana in general appearance, has occurred on Mount Rua- 
pehu and the Tararua Range at an altitude of about 4,000 
feet. 
It is chiefly distinguished by the structure of the palpi, 
which are greyish-white, darker apically, with the second joint 
thickened with scales, apex truncate, terminal joint very short, 
hardly projecting. 
The perfect insect appears in December and January. 
TORTRIX MELANOSPERMA. 
(Tortriz melanosperma, Meyr., Trans. N.Z. Inst., xlviii., 414.) 
(Plate XLVIL, fig. 4 @.) 
This dull-looking insect has occurred on Arthur’s Pass 
at an altitude of about 3,000 feet above the sea-level. 
The expansion of the wings is about { inch. The fore-wings 
are elongate with the apex rather pointed and the termen 
oblique; pale grey and very glossy with scattered black scales 
tending to form. rows; the costa is clouded with whitish and there 
is a conspicuous black dot in the dise at 3. The hind-wings are 
pale grey. 
The perfect insect appears in January. It is evidently 
attached to open mountain country, but apparently very 
loeal. 
TORTRIX AERODANA. 
(Tortrix aérodana, Meyr., Proc. Linn. Soc. N.S.W. 1881, 520; 
rans Neva ENS exe, Oo.) 
(Plate XLV., fig. 17 @.) 
This very obseure-looking little species was discovered 
by Mr. Meyrick at Hamilton in 1880. 
The expansion of the wings is about 2 inch. The fore-wings 
are narrow with the termen very oblique, pale greyish-white 
without distinct markings. The hind-wings are brownish-grey. 
There is considerable resemblance between this speties 
and 7’. indigestana. T. aérodana is, however, much smaller, 
the termen of fore-wings much more oblique; the edge of 
the central band is often not traceable in either, but when 
perceptible it is much more oblique than in 7. indigestana. 
The perfect insect was found in January, frequenting 
heathy serub. 
Described and figured from one of the original speci- 
mens kindly given to me by Mr. Meyrick. 
TORTRIX CHARACTANA. 
(Tortriz charactana, Meyr., Proc. Linn. Soc. N.S.W., 1881, 492, 
Trans, N.Z: Inst., xv., 50.) 
(Plate XXIV., figs. 33, 34, 35 varieties; Plate III., fig. 17 
larva.) 
This very pretty and distinctly-marked species appears 
to be generally distributed throughout the country. 
The expansion of the wings is about ? inch. The fore-wings 
are white with black markings; there is a rather broad, jagged 
transverse line at the base; an oblique line from before the 
middle of the costa, becoming indefinite towards the tornus ana 
enitting a fainter branch which returns to the costa before the 
apex; there are four dots on the costa beyond the middle, sev- 
eral minute dots near the middle of the termen and along the 
dorsum. The hind-wings are white with a few small grey spots. 
There appears to be considerable variation. One small 
male from Invereargill has the fore-wings very pale brown- 
ish-grey with the markings obscure except a short, thick 
oblique mark on the costa. Another from Otira has the 
fore-wings very pale brown with a deep red kidney-shaped 
spot on the costa, the usual dotted markings being indicated 
in dull reddish-brown. (Fig. 34). 
The larva, which feeds between joined leaves 
of Coprosma rotundifolia, in October and January,
