228 XV.—THE TORTRICIDAE. 
3. 
is about 2 inch in length, stout, rather flattened 
and rapidly tapering from a little before the middle, 
with the segmental divisions deeply excised. The head is 
pale ochreous with brown markings; the rest of the body 
rather dark vivid green with a very bright crimson dorsal 
streak; the segmental divisions are marked in yellow; there 
are a few indistinct shining warts emitting short bristles. 
It is rather a striking larva for a Tortrix and much less 
active than usual. 
The pupa is enclosed in a silken cocoon between joined 
leaves of the Coprosma. 
The perfect insect appears from September till Janu- 
ary, and again in April or May, there being clearly two 
distinct broods in the year. I have noticed that the black 
and white form, treated here as the type, frequents beech 
forests on mountains at elevations of about 3,000 feet. Mr. 
Meyrick records the capture of nine specimens near Christ- 
church, but in my experience the insect is a rare one. This 
species might perhaps be mistaken for a small and very 
pale variety of Ctenopseustis obliquana, but on closer 
examination it will be found that it has no real affinity 
with that insect. 
TORTRIX ORTHROPIS. 
(Tortrix orthropis, Meyr., Trans. Ent. Soc. Lond., 1901, 573.) 
(Plate XXIV., figs. 11, 31, 32 varieties.) 
This brightly-ecoloured and variable species has oc- 
eurred at Ohakune, Wellington, Nelson, Dunedin, Wynd- 
ham and Invercargill. 
The expansion of the wings is slightly over 3 inch. The 
fore-wings have the costa strongly arched, the termen indented 
below the apex and rounded beneath; pale brownish-ochreous to 
bright reddish-brown, there is a darker basal area; two very 
dark reddish-brown elongate spots on the costa, one at 4 and the 
other just before the apex, the space between these spots being 
more or less clouded with the darker colour, the whole thus 
forming a large and conspicuous costal patch; there is also a 
much less distinct shaded patch near the tornus. The hind-wings 
are very pale brownish-ochreous spotted with grey. 
In addition to the variation above indicated, the lighter 
portions of the fore-wings are often faintly mottled with 
reddish-brown, and there are frequently two small black 
spots close to the termen near the middle, and several simi- 
lar dots above the tornus. Specimens from the southern 
portions of the South Island have all the wings strongly 
clouded with dark brownish-grey, and but for the fact that 
the markings in both the northern and southern forms are 
identical, each would most certainly be ranked as consti- 
tuting a distinct species (fig. 11.) 
The perfect insect appears in December and January. 
It seems to chiefly frequent scrubby forest, composed 
mainly of Fuchsia, where the males are sometimes fairly 
common. The female has not yet been discovered. 

TORTRIX POSTVITTANA. 
(Tortriz postvittana, Walk., Cat. xxviii., 297; Meyr. Proc. Linn. 
Soc. N.S.W., 1881, 502; retractana, Walk., Cat. xxviii., 288; 
scitulana, ib. 298; basialbana ib. 299; secretana, ib. 300; 
consociand, ib. 311; reversana, ib. 321; foedana, ib. 321; 
vicariana, Walk., Char. Het. 82.) 
(Plate XE te 0 ass) 
This very common Australian species was first de- 
tected in New Zealand in 1891 and since that time has 
frequently occurred in the neighbourhood of Wellington. 
Mr. Clarke reports that it is very common in the Auckland 
Domain. It is also abundant around the Manawatu River 
near Ashhurst, and at Nelson. 
The expansion of the wings is slightly over # inch. 
The fore-wings have the costa very strongly arched; there is 
an ochreous-brown basal area extending to 4 of the costa and to 
8 of the dorsum; the rest of the wing is bright reddish-brown, 
the boundary between the two areas being slightly waved and 
very oblique; there are a few small brown marks on the basal 
area and sometimes a small ochreous patch on the terminal area 
near the tornus. The hind-wings are pale ochreous with a faint 
grey mottling. 
The larva feeds on Pelargonium. It joins two leaves 
together and lives between them, changing into a pupa in 
the same situation. 
The perfect insect appears from October till March. 
It is often observed on windows and seems to frequent gar- 
dens and other cultivated localities. Specimens are occa- 
sionally met with in the middle of winter. 
Mr. Meyrick states that this species is extremely abun- 
dant in Australia, where its larva feeds on a great many 
different plants and it has no doubt been introduced from 
that country to New Zealand through civilization. 
TORTRIX TOROGRAMMA. 
(Cacoecia torogramma, Meyr., Trans. Ent. Soc., Lond., 1897, 388.) 
(Plate XXVL., fig. 27 @.) 
This very distinct and remarkable-looking species has 
occurred at Kaeo, Auckland and Wellington in the North 
Island, to which it appears to be confined. 
The expansion of the wings is slightly under # inch. The 
fore-wings are pale purplish-grey with brown and white mark- 
ings; there are two oblique brownish transverse lines from about 
4 of the costa to about 3 of the dorsum; two similar lines close 
together enclosing an elongate wedge-shaped white patch from 
2 
3 of the costa nearly reaching to the tornus; there are one or 
two brown dots near the apex and a more or less distinct discal 
dot; the cilia are brown. The hind-wings are pale brownish-grey. 
Specimens from the northern parts of the North Island 
are apparently darker in colour than those from the neigh- 
bourhood of Wellington. 
The perfect insect appears in September and October, 
and again in February and March, there being evidently 
two distinct broods in a season. It frequents dense forests 
and is especially attached to the silver tree-fern (Cyathea 
dealbata), its general colouring being highly protective
