apex, and a series of apical and terminal dots. The hind-wings 
are pale grey, with faint purplish reflections. 
The perfect insect appears in January, and frequents 
the faded foliage of the Nikau Palm. 
Genus 1d. 

PROTERODESMA, Meyr. 
Head rough. Labial palpi long, curved, second joint rough- 
sealed beneath, with numerous bristles. Maxillary palpi long, 
drooping. Fore-wings with 8-11 becoming obsolete near costa 
and connected by an indistinct subcostal bar. Hind-wings ovate- 
lanceolate; 6 to costa. 
An endemic genus represented by two species. 
PROTERODESMA BYRSOPOLA. 
(Proterodesma byrsopola, Meyr., Sub-antarctice Ilds. of N.Z., 
Bee hts) 
CRia tes XC Ve tee Ne es, Oey) 
This interesting species was originally discovered at 
Auckland Island during the scientific expedition of No- 
vember, 1907, but Mr. Philpott has since found it at Inver- 
eargill and at Orepuki. . 
The expansion of the wings is considerably over # inch. 
The fore-wings are elongate-elliptical with the termen very 
obliquely rounded; ochreous more or less speckled with brown, 
except on the veins and towards the costa and dorsum; there is 
a broken black line on the fold; a binoad, dark brown longitu- 
dinal streak in the disc from the base to about 3, thence deflected 
towards the tornus and an indistinct blackish discal mark. The 
hind-wings are greyish-ochreous very faintly tinged with purple. 
In the female the body is very much larger and heavier and 
the wings relatively narrower and more pointed, the insect 
thus clearly approaching a semi-apterous condition; the general 
colouring is darker and duller, the brown speckling being more 
extensive, and the discal mark darker and more distinct than 
in the male. 
This species varies considerably in the distinctness of 
the markings. 
The perfect insect appears from October till Janu- 
ary. At Auckland Island it was found in the rata forest, 
resting on the rough undersurface of dead logs lying on 
the ground. I have never observed either sex on the wing 
and it is perhaps doubtful if the female is able to fly. 
Mr. Philpott has taken this species on Longwood Range, 
at an altitude of 3,000 feet above the sea-level. 
PROTERODESMA MYSTICOPA. 
(Tinea mysticopa, Meyr., Trans. N.Z. Inst., xlvi., 115.) 
(Plate Sin eo) 
This species has occurred at Greymouth, Dunedin and 
Invereargill. It is also found on the Chatham Islands. 
The expansion of the wings is § inch. The fore-wings are 
rather narrow with the apex slightly rounded and the termen 
oblique; ochreous, heavily speckled and clouded with brown, ex- 
cept on a wide irregular streak along the basal portion of the 
dorsum; there is a series of elongate black marks on the fold, 
and another series in the disc beyond the middle. The hind- 
wings are pale ochreous tinged with dusky brown along the 
termen. 
Varies somewhat in the brown and ochreous colouring, 
which is much brighter in some specimens than in others. 
The perfect insect appears from September till De- 
cember, and frequents forest. 
TINEIDAE. 
Genus 16—TRITHAMNORA, Meyr. 
Head rough. Labial palpi moderate, porrected, second joint 
rough-sealed beneath. Maxillary palpi long, drooping. Fore-. 
wings with sub-dorsal tufts; all veins present. Hind-wings 
elongate-ovate. 
Another endemic genus containing one species. 
TRITHAMNORA CERTELLA. 
(Tinea certella, Walk., Cat. xxviii., 484; Trithamnora improba, 
Meyr., Trans. N.Z. Inst., xlv., 29.) 
(Plate LVI, fie, dba 5016) 9°) 
This very dark-looking insect has occurred at Well- 
ington. 
The expansion of the wings of the male is about & inch, of 
the female nearly # inch. The fore-wings are rather elongate 
with the cilia expanded at the tornus, very rich brownish-black 
with a large black patch lon the costa extending from the base 
to % but not reaching the dorsum; there vs a series of tufts of 
dull yellowish raised scales along the lower edge of the costal 
patch which itself is strongly waved; the cilia are blackish- 
brown, narrowly barred with dull white. The hind-wings are 
deep brownish-black, darker towards the apex. The female is 
considerably larger and much paler in colour than the male, 
with the basal $ of the fore-wings (except along the dorsal edge) 
deep chocolate-brown. The hind-wings are pale greyish-ochre- 
ous, with very faint purplish reflections. 
This species was at one tima confused with Tinea con- 
ferta, but is a much darker and more richly-coloured 
insect ; the patches of raised yellowish-scales also constitute 
a good distinction. 
The perfect insect appears in November, December 
and January, and frequents dark forests. When at rest 
with closed wings, this species is manifestly protected by 
its resemblance to bark, the tufts of raised scales on the 
fore-wings are then very conspicuous and certainly give 
the impression of minute lichens growing on the bark. 
Genus 17.—LYSIPHRAGMA, Meyr. 
Head loosely scaled. Labial palpi curved, ascending, second 
joint with rough projecting scales beneath, terminal joint 
broadly flattened. Maxillary palpi long, drooping. Fore-wings 
with subdorsal tufts; all veins present. Hind-wings elongate- 
ovate, transverse vein sometimes absent between 3 and 4. (Plate 
K., figs. 31, 32, 33 neuration and head of Lysiphragma epixyla.) 
An endemic genus containing three species. 
LYSIPHRAGMA MIXOCHLORA. 
(Lysiphragma mixochlora, Meyr., Trans. N.Z. Inst., xx., 105.) 
(Plate XXXIX., fig. 9 @.) 
This very pretty green species has occurred in the 
North Island at Auckland, Makotuku, Kaitoke and Well- 
ington, and in the South Island, on the Lyttelton Hills. 
The expansion of the wings is about # inch. The fore-wings, 
which have the costa strongly arched and the termen obliquely 
rounded, are rather dull pale green more or less mottled with 
brighter green; there is a very conspicuous tuft of black scales 
on the dorsum near the base followed by a series of short black 
streaks and a smaller tuft of rusty red scales; a series of short 
black bars is situated on the costa and a conspicuous cream- 
coloured patch near the apex, bordered with blackish-brown to- 
wards the base; there is a terminal series of blackish dots and 
a number of brown bars on the cilia.- The hind-wings are white,
