XV—THE TORTRICIDAE. 
The perfect insect appears in April. 
Described and figured from specimens kindly given to 
me by Mr. Philpott. 
yenus 5.—HKURYTHECTA, Meyr. 
Antennae in male ciliated. Palpi moderate, porrected, sec- 
ond joint with projecting scales above and beneath, terminal 
short. Thorax without crest. Fore-wings with vein 4 absent, 7 
separate, to termen, or absent. Hind-wings with veins 6 and 7 
approximated at base. (Plate E., figs. 25, 26 neuration of Hury- 
thecta zelaea; fig. 27 head of ditto.) 
Confined to New Zealand, being a local development of 
Epichorista. The first two species have vein 7 of the fore- 
wings absent, in the rest it is present; the alliance being 
close in all other respects, and the genus being sufficiently 
defined as a whole, it is needless to separate the two forms. 
(Meyrick. ) 
There are nine New Zealand species. 
EURYTHECTA ROBUSTA. 
(Zelotherses robusta, Butl. Proce. Z.S.L., 1877, 403, Pl. xliii., 17; 
Steganoptycha negligens, ib., 404, Pl. xliii., 18; Hurythecta 
robusta, Meyr., Trans. N.Z. Inst., xv., 56.) 
(Plate XXVI., fig. 23 ¢@.) 
This very distinetly-marked little species was discov- 
ered by Fereday, at Christchurch, over 50 years ago. It 
has since been taken at Alexandra and on Ben Lomond, 
Lake Wakatipu, and was re-discovered by Mr. S. Lindsay 
at Harewood, near the Waimakariri River, Christchurch, in 
1925. 
The expansion of the wing is about 3 inch. The fore-wings 
are lanceolate, rather narrow, with the termen very oblique, 
white, pale grey, ochreous or reddish-ochreous-brown with well- 
defined dark brown or blackish markings; there is a narrow, 
oblique band near the base; a moderate oblique band from before 
the middle of the wing to the dorsum at 2; three small oblique 
spots on the costa between the central band and the apex; a 
fourth spot at the apex, and two or three others on the termen. 
The hind-wings are pale brown. 
The perfect insect appears from October till April, 
and frequents grassy situations. 
EURYTHECTA ZELAFA. 
(Hurythecta zgelaea, Meyr., Trans. Ent. Soc. Lond., 1905, 233.) 
(Plate XXVL., fig. 10 @.) 
This interesting little species was discovered by Mr. 
J. H. Lewis at Ida Valley, Central Otago, and subse- 
quently observed by him near Arrow. 
The expansion of the wings is slightly under 4 inch. The 
fore-wings are lanceolate, round pointed, obviously more elongate 
than in HE. robusta, dull ochreous speckled with dull brown and 
white; there is a series of small brown marks on the costa, the 
spaces between being clouded with white; a dark brown spot 
before the middle and another on the tornus; the cilia are dull 
ochreous mixed with brown, The hhind-wings and cilia are rather 
dark brown. 
The larva inhabits a pear-shaped case, composed of 
sand, very much attenuated at its posterior extremity. It 
was found by Mr. Lewis on lichen-covered rocks, the larva 
no doubt feeding on the lichens. 
The perfect insect appears in November and Decem- 
ber. Mr. Lewis states it is very common amongst rocks, 
but evidently has a very restricted range. 
EURYTHECTA VARIA. 
(Hurythecta varia, Philp., Trans. N.Z. Inst., xlviii., 421.) 
(Plate -XLV., fig. 8 9.) 
This very distinetly-marked little species was diseov- 
ered by Mr. Fenwick at Kaikoura. It has also oceurred 
at Horseshoe Lake near Christchurch. 
The expansion of the wings is § inch. The fore-wings are 
dull white; there are three large black blotches, one near the 
base, another near the middle and a third just before the tornus; 
there is a reddish-ochreous patch on the costa from the base to 
about the middle, speckled with blackish scales; three similar 
small roundish patches before the apex, a fourth below the apex 
and a large irregular patch on the termen. The hind-wings are 
dark blackish-brown. The head and thorax are reddish-ochreous. 
The perfect insect appears in December and March 
and is common in swampy places. 
Deseribed and figured from a specimen in the Fen- 
wick collection. 
EURYTHECTA TRIMACULATA. 
(Hurythecta trimaculata, Philp., Trans. N.Z. Inst., xlvii., 198.) 
(PlateeeXvil sie Gar anor) 
This very distinectly-marked little insect was discoy- 
ered by Mr. Philpott near Queenstown, Lake Wakatipu. 
Mr. 8. Lindsay has also found it fairly commonly at 
Horseshoe Lake, near Christchurch. 
The expansion of the wings of the male is 2 inch; of the 
female seven-sixteenths of an inch. The fore-wings of the male 
are pale grey, sprinkled with darker grey; there is a broad, 
oblique, bronzy-brown bar on the dorsum at about 4; a fainter 
patch on the tornus and several small indistinct marks on the 
costa and termen. The hind-wings are grey. In the female the 
fore-wings are rather dark grey thinly speckled with brownish- 
grey; there is a broken oblique black transverse line near the 
base; a broad black transverse line at 4; several fine broken 
markings near the middle of the wing and three short bars on 
the apical half of the costa; a very broad, triangular black patch 
on the tornus, its apex nearly touching the costa; another patch 
below the apex and several small black marks between these. 
The hind-wings are bronzy-grey, darker near the apex and ter- 
men. 
The perfect insect appears in November and Decem- 
ber, and is found on open country, sometimes from 2,000 
to 3,000 feet above the sea-level. 
EURYTHECTA POTAMIAS. 
(Lurythecta potamias Meyr., Trans. N.Z. Inst., xli., 11.) 
(Plate XXXVI. fig. 11 A. 220.) 
This interesting species was discovered by Mr. Phil- 
pott at Riverton near Invereargill. a
