NXV.—THE 
The larva is polyphagous and has been found feeding 
on the following plants: Suttoma australis, Aristotelia 
racemosa , Nothopanax arboreum, Myoporum  laetum 
(Ngaio), Leptospermwm scoparium (Manuka), and Muhlen- 
beckia. It also attacks apples and is often rather destruc- 
tive in orchards, joining the leaves of the tree to the fruit 
by means of silken threads and eating the surface of the 
apples. It does not, however, live inside the apple like its 
introduced congener Laspeyresia pomonella. In addition 
the larva feeds on honeysuckle and many other introduced 
plants. 
The length of the full-grown larva is about 1 inch, 
rather slender, tapering towards the posterior extremity, 
pale green with darker green dorsal line and yellow seg- 
mental divisions; there are a few scattered whitish hairs; 
the head is yellowish, darker coloured on the sides. It 
feeds between two leaves joined together or, where more 
convenient, within a single curled leaf. The pupa is freely 
enclosed in the same situation. 
The perfect insect may be found throughout the entire 
year, but is most abundant during the summer months. It 
is very common in gardens and other cultivated places and 
frequently enters houses. 
TORTRIX FLAVESCENS. 
(Teras fiavescens, Butl., Proc. Zool. Soc. Lond., 1877, 402; 
Cacoecia acrocausta, Meyr., Trans. N.Z. Inst., xxxix., 116.) 
(Plate = XX Vin fies Ie oe 2°.) 
This species has occurred at Auckland, Wellington, 
Christchurch, Otira, Dunedin, and Invereargill. 
The expansion of the wings is slightly over # inch. The 
fore-wings have the apex obtuse and the termen rounded and 
slightly oblique; rather dull yellowish-ochreous; the basal area 
to 2 is more or less clouded with brown and the costal edge is 
rusty red; there is often a number of blackish-grey spots near 
the termen and dorsum; below the apex the cilia are rusty red 
tipped with grey, the rest of the cilia being entirely yellow. The 
hind-wings are pale ochreous with faint grey spots. The female 
has rather more elongate wings than the male, is pale yellow 
with a series of rusty-brown spots on the costa and one spot on 
the termen below the apex. 
Mr. Philpott informs me that the perfect insect ap- 
pears from the middle of October until the end of January. 
It always frequents forest and is a common species in the 
neighbourhood of Invereargill. 
TORTRIX FASTLIGATA. 
(Tortrix fastigata, Philp., Trans. N.Z. Inst., xlviii., 422. 
(Plate XaL1V., fig, 26 @5 27 9.) 
This species, which is very closely allied to 7’. flaves- 
cens, was discovered by Mr. Philpott on Longwood Range 
at an elevation of 3,000 feet above the sea-level. It has also 
occurred on the Hunter Mountains at 3,500 feet. 
The expansion of the wings is about 1 inch. The male 
is very similar to the same sex in 7. jflavescens, but differs in 
having longer and narrower wings. In the female the fore-wings 
have “an obscure basal striga with a blunt projection outwardly 
TORTRICIDAE. 231 
at the middle and the triangular costal patch is connected with 
the curved median mark beneath it.” 
The perfect insect appears in December and January, 
and is found on open mountainous country between 3,000 
and 4,000 feet above the sea-level. Mr. Philpott states that 
Tortriz fastigata is probably attached to open country and 
T. flavescens to forest. 
Described and figured from specimens in Mr. Philpott’s 
collection. 
TORTRIX FERVIDA. 
(Cacoecia fervida, Meyr., Trans. Ent. Soc. London, 1901, 572.) 
(Plate XXvVi,, fea 27 9%) 
This richly-coloured little species has occurred at Kai- 
toke near Wellington, Otira Gorge and at West Plains, near 
Invercargill. 
The expansion of the wings is slightly over 4 inch. The 
fore-wings are rich pinkish-brown often slightly tinged with 
purple; there is a rather indistinct basal patch of crimson-brown; 
a curved, irregular band of very dark crimson brown near the 
middle of the wing often divided into several branches before the 
dorsum; another similar band from about % of the costa to the 
tornus; a small triangular mark of the same colour at the apex; 
the edges of all these bands are strongly sprinkled with golden 
yellow scales. The hind-wings are dark grey, darker near the 
termen. The female has the fore-wings slightly longer and nar- 
rower than the male and all the transverse bands are indistinct, 
except the one reaching from the costa to the tornus. 
Some of the males have the spaces between the bands 
considerably paler in colour. 
The perfect insect appears in November and frequents 
forest. It is not a common species. 
TORTRIX SPHENIAS. 
(Cacoecia sphenias, Meyr., Trans. N.Z. Inst., xli., 11.) 
(Plate XLYV., fig. 28 ¢.) 
This bright-looking species has occurred at Dunedin 
and Invercargill. 
The expansion of the wings is nearly $~ inch. The fore- 
wings are pale straw-colour much speckled and clouded with. red- 
dish-brown; there is a narrow basal area, a very broad, irregular 
median band, clouded with reddish-brown, and a very deep, dis- 
tinct wavy reddish-brown band from the costa before the apex 
to the termen below the middle. The hind-wings are rather dark 
grey. 
This species is evidently very closely allied to T. fer- 
vida, from which it is stated to differ in the longer ciliations 
of the antennae of the male and the more oblique termen 
ot tke fore-wings. 
The perfect insect appears in December and January. 
Deseribed and figured from a specimen kindly given to 
me by Mr. Clarke. 
TORTRIX MOLYBDITIS. 
(Tortriz molybditis, Meyr., Trans. N.Z. Inst., MKS Ge) 
(Plate “XVEn fig) 3 45 Plate lily fig? 4 larva in case; fig. 5 
ditto withdrawn from case.) 
This interesting little species has occurred at Kaeo, 
north of Auckland, Waimarino, Wellington, Invercargill 
and Stewart Island.
