XANTHORHOE CYMOZEUCTA. 
(Larentia obarata, Meyr., nec. Feld., Trans. N.Z. Inst. xvi., 82; 
Huds., N.Z. Moths, 66, pl. vii., 45; Xanthorhoe cymozeucta, 
ibs; exv.j020>) 
(Plate XV, fe 9 (A 0N es) 
This interesting little species, which is closely allied 
to X. obarata, has occurred at Waimarino, Ohakune and 
Wellington in the North Island. In the South Island it 
has been found at Christchurch, Otira, Mount Hutt, 
Dunedin, Queenstown and Bold Peak, Lake Wakatipu. 
The expansion of the wings is almost 1 inch. The fore- 
wings, which have the apex prominent and the termen strongly 
bowed, are rather dark brownish-ochreous clouded with blackish 
on the median band; the small basal patch, which contains two 
brownish lines, is margined by a fine wavy whitish line; the 
space between this and the median band is clouded with dull 
reddish; the median band is broad with a strong angulation on 
its outer edge near the middle; it is irregularly bordered with 
whitish lines and contains one or two indistinct paler patches 
and a black discal dot; beyond the median band there is a dull 
reddish or purplish subterminal shading and a very regularly 
waved fine subterminal line; there is a terminal series of black- 
ish crescentic marks and the cilia are pale ochreous barred with 
dark brown. The hind-wings are whitish with a very pale 
greyish basal area and several faint wavy transverse lines; 
there is a terminal series of brownish crescentic marks and the 
cilia are pale ochreous barred with brown. The female is rather 
darker and duller than the male, with the transverse lines more 
deeply indented. 
A variety occasionally occurs in which the fore-wings 
are creamy-white, with a very conspicuous blackish-brown 
median band, paler in the centre; there is a small brownish 
basal patch, and the whole of the costa is broadly edged 
with very pale reddish-brown. 
The perfect insect appears in January, and inhabits 
damp forests. It is a very local species and seldom now 
met with. About’ forty years ago it was recorded by 
Fereday as common on the Canterbury Plain, and 
especially attached to gorse hedges. 
XANTHORHOE GLACIATA. 
(Xanthorhoe glaciata, Huds., Ent. Mo. Mag. 1xi., 220.) 
(Plate LII., fig. 11 @.) 
This very distinct and beautiful species was discovered 
by Mr. C. E. Clarke on Mount Moltke, Franz Joseph 
Glacier, at an elevation of 5,600 feet above the sea-level. 
The expansion of the wings is almost 14 inches. The fore- 
wings, which have the costa strongly arched near the apex and 
the termen obliquely rounded, are bright yellow-ochreous with 
blackish-brown and bluish-white markings; a small bluish-white 
basal patch, heavily sprinkled with blackish scales; a pale 
yellowish-brown sub-basal band edged with blackish-brown; 
except on costa a clear band of yellow-ochreous before median 
band; inner edge of median band from about 4 of costa to about 
4 of dorsum, margined with blackish-brown, with two deep 
rounded indentations above and below middle; centre of median 
band bluish-white, heavily sprinkled with blackish-brown scales; 
outer edge of median band from } of costa to 2 of dorsum, with 
a very strong rounded double projection slightly below middle; 
outer portion of band composed of several wavy lines of blackish- 
brown scales; a large suffused crescentic patch of dull brown

on termen below apex; a subterminal series of diffused bluish- 
white spots; an obscure terminal series of brown crescentic 
marks; cilia brownish-ochreous. The hind-wings are pale 
brownish-ochreous, with a broad suffused greyish terminal band, 
and numerous fine broken greyish lines and dots on basal 4; 
a distinct grey discal dot; cilia dull ochreous-brown. 
The perfect insect appears in January, and may be 
looked for on mountains in the South Western part of the 
South Island. 
Deseribed and figured from a slightly damaged speci- 
men kindly lent to me by Mr. Clarke. 
XANTHORHOEH PRYMNABA. 
(Xanthorhoe prymnaea, Meyr., Trans. N.Z. Inst. xliii., 73.) 
(Plates oe Oni Gema eect) 
This very striking species was discovered on the Mount 
Arthur Tableland, at an elevation of about 4,000 feet 
above the sea-level. Although apparently common in that 
locality it has not, so far, been found elsewhere. 
The expansion of the wings is about 14 inches. The fore- 
wings, which have the costa slightly arched and the apex rather 
prominent, are bright ochreous with rich reddish-brown mark- 
ings; the basal patch is faintly indicated by two indistinct trans- 
verse lines; the median band is broad, very distinct with a very 
strong double projection on its outer edge; the costal half of 
the median band is clear ochreous and contains an elongate 
black discal spot; the terminal area is strongly shaded with 
pinkish-brown except on the apical patch and along the edge of 
the median band; there is a fine wavy whitish subterminal line; 
the cilia are crimson-brown barred with darker brown. The 
hind-wings are bright ochreous with brown terminal marks and 
crimson-brown cilia. 
In the female all the markings are much paler and less dis- 
tinct than in the male. 
The perfect insect appears at the end of January, 
and frequents the limestone valleys on the Mount Arthur 
Tableland. It is probably out for a very brief season, as 
I have only once met with it, when, however, it was very 
common. 
XANTHORHOE CLARATA. 
(Larentia clarata, Walk., Cat. xxiv., 1197; Butl., Cat. N.Z. Lep. 
pl. iii, 14; Cideria pyramaria, Gn., Ent. Mo. Mag. v., 93. 
Larentia clarata, Meyr., Trans. N.Z. Inst. xvi., 79.) 
(Plate XIV., fig. 26 @, 27 9.) 
This very conspicuous species has occurred at Mount 
Egmont, Waimarino, Waiouru, and on the Tararua Range 
in the North Island. It is common and generally distri- 
buted throughout the South Island. 
The expansion of the wings of the male is nearly 14 inches; 
of the female about 14 inches. The fore-wings are pale ochreous- 
brown with numerous fine wavy dark brown and broad white 
transverse lines; there are two oblique white lines near the 
base; a broad wavy white line along the outer edge of the 
median band with a double prominent projection near the 
middle; a very wavy, somewhat broken white subterminal line 
and a curved apical streak; between the white lines there are 
rather faint wavy dark brown, or blackish, lines; two or three 
white spots of very variable size are situated in the middle of 
the median band, the uppermost containing a black discal dot. 
The hind-wings are bright ochreous. The cilia of all the wings 
are whitish-ochreous strongly barred with dark brown.
