XVII,—THE 
All the markings appear to be very variable and in 
some specimens the white discal blotches are replaced by 
pale brown; others are almost wholly coppery purple. A 
very beautiful variety from Mr. Clarke’s collection is 
figured on Plate XLVII, fig. 17. 
According to Mr. Meyrick the larva has 16 legs, is 
moderately stout, cylindrical, rather tapering at both ends; 
dull light greenish-ochreous; there is a narrow ochreous- 
whitish dorsal line bordered on each side by a slender dull 
reddish-brown streak, coalescing towards extremities; the 
head is brownish-ochreous. It feeds in December amongst 
loosely spun-together leaves of ‘Totara (Podocurpus totara.) 
I have observed the larva in great abundance on the sum- 
mit of Arthur’s Pass (3,000 feet) feeding on Phyllocladus 
alpwmus. 
The pupa is enclosed in a thin cocoon. 
The perfect insect appears from September till March 
-and frequents open forest and serub. 
ORTHENCHES PRASINODES. 
(Orthenches prasinodes, Meyr., Trans. N.Z. Inst., xviii., 176.) 
(Plate XXXVI., fig. 5 9.) 
This rather obscurely-marked species has oecurred at 
Wainuiomata, near Wellington, and at Christchurch and 
Greymouth, but is apparently a very rare insect. 
The expansion of the wings is = inch. The fore-wings are 
rather elongate with the apex and tornus rounded; yellowish- 
brown with numerous obscure pale Ochreous dots along the dor- 
sum and some of the veins and very faint purplish reflections; 
there is a very indefinite dark brown transverse shading before 
the middle; a streak before the apex and several darker dots on 
the termen and dorsum, The hind-wings are very pale greyish- 
ochreous, almost white. 
The perfect insect appears from December till March, 
and frequents forest. 
ORTHENCHES SEMIFASCIATA., 
(Orthenches semifasciata, Philp., Trans. N.Z. Inst., xlvii., 200; 
Orthenches similis, Philp., ib. lv., 211.) 
(Plate XL., fig. 3 9.) 
This neatly-marked species has occurred at Kaitoke, 
near Wellington, in the North Island. In the South 
Island it has been taken on Mount Arthur at 3,500 feet, at 
Queenstown and at Hakapoua, Fiord County. 
The expansion of the wings is about #4 inch. The fore- 
wings are elongate-oblong with the costa strongly arched before 
the apex, whitish, mottled and spotted with greyish-brown; there 
is a number of short bars of variable size along the margins of 
the wing; an irregular patch in the disc before the middle and 
a larger patch beyond the middle; a large cloudy patch on the 
termen containing a broad oblique bar of the grownd colour; 
there is a strong iridescent purplish sheen on the fold and below 
the apex; the cilia are whitish barred with greyish-brown. The 
hind-wings are greyish-ochreous. 
The perfect insect appears in December and January, 
and may be looked for in open beech forests. 
ORTHENCHES VINITINCTA. 
(Orthenches vinitincta, Philp., Trans. N.Z. Inst., xlix., 244.) 
(Plate XXXVIIL., fig. 20 @.) 
This very beautiful species was discovered by Mr. C. 
C. Fenwick at Rowallan, Waiau, Southland. 



TINEIDAE. 329 
The expansion of the wings is about # inch. The fore- 
wings, which are rather elongate with the apex and tornus very 
much rounded, are glaucous green with black markings and 
warm reddish-brown mottling; there are three large irregular 
patches of reddish-brown on the dorsum and a very conspicuous 
almcst round paich on the subterminal area; a series of smail 
black marks on the costa; several irregular patches of blackish 
seales in the dise and a black spot on the inner edge of the 
reddish subterminal patch; all the reddish patches have purplish 
reflections and are sprinkled with a few purplish scales; the 
cilia are warm yellowish-brown strongly barred with reddish- 
brown; there are two conspicuous tufts of black cilia at the 
tornus. The hind-wings are pale ochreous; there are small tufts 
of black and reddish-brown cilia at the apex, the rest of the cilia 
being whitish-ochreous. 
Varies considerably in depth of colour and distinctness 
of markings. 
The perfect insect appears in December, and fre- 
quents coastal forest. Its colouring would evidently be 
highly protective on lichen-covered tree trunks. 
Described and figured from the type specimen in the 
Fenwick collection. 
ORTHENCHES POLITA. 
(Orthenches polita, Philp., Trans. N.Z. Inst., 1., 131.) 
(Plate XLVI., fig. 4 9.) 
This very handyome species was discovered by Mr. 
Philpott at Tisbury, near Invereargill. 
The expansion of the wings is seven-sixteenths of an inch. 
The fore-wings, which have the apex rather pointed and the 
termen very oblique, are golden-ochreous-brown with vivid pink 
reflections, especially at the base; there are three large white 
blotches in the dise at 4, 4 and 4, the middle blotch touching 
the dorsum, and two longitudinal deep blue stripes, oné on the 
fold interrupted, the other much shorter above the fold. The 
hind-wings are pale greyish-white. ' 
The perfect insect has been taken in February and 
July. 
Described and figured from the type specimen kindly 
lent to me by Mr. Philpott. 
ORTHENCHES CHLOROCOMA. 
(Orthenches chlorocoma, Meyr., Trans. N.Z. Inst., xviii., 175.) 
(Plate XXXVIII., fig. 19.) 
This rather dull-looking species has occurred at Auck- 
land, on the hills around the French Pass near Nelson, 
and at Christchurch. 
The expansion of the wings is about % inch. The fore- 
wings are elongate-oblong with the apex and tornus very 
rounded, dull greyish-ochreous very slightly tinged with green- 
ish; there is a conspicuous black spot on the fold at about 4 and 
a fainter mark beyond this; another conspicuous black spot in 
the dise at about 3; there is a chain of minute black marks on 
all the margins of the wing; the veins are very faintly marked 
in grey, the cilia are greyish-ochreous tinged with greenish and 
faintly barred with blackish. The hind-wings and cilia are pale 
whitish-ochreous; the cilia have a dark tuft near the apex. 
The larva, which feeds on the native broom (Curmichaelia), 
is about # inch in length, considerably flattened, strongly taper- 
ing posteriorly. The head is brownish-yellow marbled with 
blackish-brown; the body bright green; the second segment is 
edged with pink; there is a broad white lateral line; segments 
2, 3 and 4 have a single row of conspicuous black warts; the
