XV—THE TORTRICIDAE. 249 
This species is rather variable. In some specimens the 
fore-wings are much clouded with rusty-red, or brownish. 
In others there are leaden-metallic marks between the 
strigulae near the apex. 
The perfect insect appears in January. 
This species is widely distributed in Australia. 
_ BACTRA SIDERITIS. 
(Noterdula sideritis, Meyr., Trans. Ent. Soc. Lond., 1905, 232.) 
The single specimen from which this species was 
deseribed is believed to have been taken at Wellington. 
The expansion of the wings is slightly over 4 inch. The 
fore-wings are elongate, somewhat dilated posteriorly, costa mod- 
erately arched, apex obtuse, termen slightly sinuate, rather 
oblique, rounded beneath; whitish-ochreous finely strigulated with 
dark fuscous, mixed in dise and towards apex wholly suffused 
with ferruginous-ochreous; two curved posterior oblique purplish- 
leaden-metallic striae from costa at 2 and #, terminating before 
and beyond tornus; a series of undefined blackish marks between 
these, starting from an oblique leaden-metallic costal streak; a 
short direct leaden-metallic costal streak before apex: cilia grey, 
basal third with a blackish-grey line broadly interrupted with 
brownish-ochreous, at tornus whitish-ochreous. Hind-wings grey, 
terminal edge whitish; cilia light grey, with darker basal line. 
In this species the palpi are much shorter and the ter- 
men of fore-wings much less oblique than in Bactra noter- 
wula. 
IT am unacquainted with this insect.

The above is 
BACTRA XYSTROTA. 
(Bactra xzystrota, Meyr., Trans. N.Z. Inst., xliii., 62.) 
(Plate XXVI., fig. 18 @.) 
This distinetly-marked species was diseovered at New 
River, near Invercargill, by Mr. Philpott. It has also 
occurred at Owenga in the Chatham Islands. 
The expansion of the wings is 2 inch. The fore-wings, 
which have the apex acute and the termen obliquely rounded, are 
pale brownish-ochreous faintly clouded with grey in the disc; 
the veins are clearly marked in blackish-grey and there are a 
few faint greyish dots on the spaces between the veins. The 
hind-wings are dark grey with the cilia ochreous, 
The perfect insect appears in January, and frequents 
sandhills on the sea-coast. 
Described and figured from a specimen in Mr. Phil- 
pott’s collection. 
Genus 6.—LASPEYRESIA, Hiibn. 
Antennae in male ciliated. Palpi moderate, more or less 
ascending second joint arched, with short projecting scales 
beneath, terminal joint short. Thorax without crest. Fore-wings 
with vein 7 separate, to termen. Hind-wings with veins 3 and 4 
connate or stalked, 5 nearly parallel to 4, 6 and 7 approximated 
towards base. (Plate F., figs. 22, 23 neuration of Laspeyresia 
pomonella; fig. 24, head of ditto.) 
A considerable genus generally distributed, but only 
represented in New Zealand by a single introduced species. 
LASPEYRESIA POMONELLA. 
(Carpocapsa pomonella, Linn. Syst. Nat. x., 538; Meyr. Proc. Linn. 
Soc. N.S.W. 1881, 657; Trans. N.Z. Inst. xv., 61.) 
(Plate XXY., fig. 38.) 
This handsome, though destructive little insect, 1s com- 
mon in most New Zealand orchards north of the lower end 
of Lake Wakatipu. 
The expansion of the wings is about # inch. The fore-wings 
are pale grey with numerous rather wavy darker grey transverse 
lines; there is a large dark brown patch on the termen contdin- 
ing @ conspicuous Oval ring-shaped coppery mark and edged with 
black towards the tornus. The hind-wings are brownish-grey, 
darker on the termen. 
There is considerable variation in size but the colour- 
ing is very constant. 
The larva is pale pink with the head scarcely darker ; 
the second segment is pale yellowish-brown; it feeds inside 
apples and pears, forming galleries in the substance of the 
fruit, in which it deposits its dark brown exerement; when 
full fed it quits the fruit. The pupa is enclosed in a silken 
cocoon, usually attached to the trunk of an apple tree. 
The perfect insect appears from December till March, 
and is often very common in orchards, not infrequently 
entering houses. Owing to its extremely destructive habits 
it is a most notable insect, being popularly termed the 
Codlin Moth. It has received much attention from eco- 
nomie entomologists and a great deal has been written 
regarding its habits and the best means of combatting its 
ravages. It was no doubt accidentally introduced into New 
Zealand many years ago, but is now very firmly established. 
It also appears to occur in most other countries where 
apples and pears are cultivated. 
Genus 7—ARGYROPLOCEH, Hiibn. 
Palpi moderate, porrected or ascending, second joint rough- 
sealed. Thorax with posterior crest. Fore-wings without costal 
fold, vein 7 separate to termen. Hind-wings with veins 3 and 4 
connate or stalked, 5 approximated, 6 and 7 closely approxim- 
ated towards base. Posterior tibiae often tufted with scales. 
Represented in New Zealand by a single species. 
ARGYROPLOCE CHLOROSARIS. 
(Argyroploce chlorosaris, Meyr., Trans. N.Z. Inst., xlvi., 106.) 
(Plate XXVI., fig. 26 @.) 
This pretty little species appears to be very rare. It 
has occurred on the hills near Day’s Bay, Wellington Har- 
bour, Orongorongo, and at Plimmerton. 
The expansion of thé wings is considerably over 4 inch. The 
fore-wings are rather broad with the termen oblique; pale purp- 
lish-brown irregularly spotted with darker brown; there is a very 
large cream-coloured costal patch just beyond the base prolonged 
as a narrow stripe almost to the apex; there are also several 
faint cream-coloured marks on the dorsum and a reddish-brown 
spot at apex. The hind-wings are brown. 
Apparently variable in the extent of the cream- 
coloured markings. 
The perfect insect appears early in December and is 
found in dry forest on hill sides.
