X.—THE 
wings are pale ochreous-brown, in the female strongly sinuate 
below the apex, in which sex there is also a cloudy subterminal 
line. 
The perfect insect appears in April. This species 
may be recognised by its small size, dull colouring and very 
indefinite markings. 
SELIDOSEMA LUTBA. 
(Selidosema lutea, Philp., Trans. N.Z. Inst. xlvi., 119.) 
(Plate XVI., fig. 832 @, 339.) 
This very fine species was discovered by Mr. C. Fen- 
wick on Bold Peak, at the head of Lake Wakatipu, at an 
elevation of about 3,500 feet above the sea-level. 
The expansion of the wings is about 1% inches. The fore- 
wings, which have the apex slightly hooked and the termen 
strongly bowed, are warm ochreous-brown; there is a very jagged 
broken blackish transverse line near the middle of tte wing, 
distinctly marked on the dorsum and in the disc. The hind- 
wings are very pale ochreous, clouded with pale brown on the 
termen; there is a small round black discal spot. All the wings 
have a few very minute blackish terminal dots. In the female 
the apical patch and inner median area of the fore-wings is 
faintly clouded with whitish. 
The perfect insect appears from December till Feb- 
ruary, and may be looked for at the upper edge of the 
beech forest on high mountains. 
Described and figured from specimens in the Dominion 
Museum. 
SELIDOSEMA LUPINATA. 
(Cidaria lupinata, Feld., Reis. Nov. pl. exxxi., 19; Pseudocoremia 
lupinata, Butl., Cist. Ent. ii., 496; Boarmia lupinata, Meyr., 
Trans. N.Z. Inst. xxiif, 101; Selidosema humillima, Huds., 
N.Z. Moths, 83, pl. ix., 5; Selidosema lupinata, Meyr., Trans. 
N.Z. Inst. xli., 7.) 
(BlateweX Vile fic bas 6.9.) 
This rather inconspicuous species has occurred at Pae- 
kakariki, Wellington, Dunedin and Invercargill. 
The expansion of the wings is from 14 to 1% inches. The 
fore-wings are pale dull pinkish-brown; there are three short 
oblique dark brown stripes on the costa, inclined very much 
towards the termen; the first of these stripes is distinctly double, 
and the second and third partially so; there is an indistinct 
brown mark just below the apex, several slender faint streaks 
on the veins near the middle of the wing, and a very distinct 
brown shading on the dorsum. The hind-wings are very pale 
ochreous. In the female the sub-apical marking is darker and 
both fore- and hind-wings are more or less sprinkled with brown. 
This species may be distinguished from the other 
species of the genus by the peculiar ground colour of the 
fore-wings and the obliquity of the costal stripes. In S. 
lupinata the costal markings slope very rapidly from the 
base towards the termen; in other allied species these mark- 
ings are but slightly inclined, and in some slope in the 
reverse direction. 
The perfect insect appears from December till June. 
It seems to frequent cultivated places, but is not by any 
means a common species.

SELIDOSEMA RUDIATA, 
(Cidaria rudisata, Walk., Cat. xxv., 1420; Boarmia astrapia, 
Meyr., Trans. N.Z. Inst. xxii., 218; Boarmia rudiata, Meyr., 
Trans. N.Z. Inst. xxiii., 101.) 
(Plate XVI., fig. 28 ¢@; 24 9, large southern form; Plate II, 
fig. 20, larva.) 
This species is fairly common in the neighbourhood 
of Wellington, and has occurred at Kaeo, North of Auck- 
land, Thames, Arthur’s Pass, Otira, Dunedin, Invereargill 
and Stewart Island. It is probably generally distributed 
throughout the country. 
The expansion of the wings of the male is 14 inches, of 
the female 12 inches. The fore-wings are very pale ochreous- 
brown; there is a double interrupted jagged transverse line near 
the base; a rather indistinct line in the middle; a double, nearly 
continuous jagged transverse line beyond the middle; a double 
jagged subterminal line completely interrupted in the middle, 
and generally a dark patch on the termen just below the apex. 
The hind-wings are pale ochreous with a very indistinct sub- 
terminal line. There is a series of black dots on the termen of 
both fore-wings and hind-wings and the termen of the hind-wing 
is slightly indented. 
This species varies a good deal in size; the specimens 
from the south are considerably larger and have more dis- 
tinet markings, than those found in the vicinity of Wel- 
lineton. 
The egg is oval, shghtly squared «at one end, pale 
bronzy-blue, with numerous hexagonal depressions irregu- 
larly arranged. 
The larva when full-grown is about 14 inches in 
length, cylindrical, of even thickness throughout, and 
almost uniform dull greyish-brown in colour, occasionally 
with a series of small oblong back marks on segments 5, 
6, 7, 8, and 9. It is also sometimes irregularly streaked 
and mottled with blackish. It feeds on the young leaves 
and buds of ake ake (Olearia forsteri), rangiora (Brachy- 
glottis repanda) and tauhinu (Cassinia). It is extremely 
difficult} to find as it almost exactly resembles a twig of its 
foodplant, on which it remains motionless for hours at a 
time. Full-grown larvae are met with in November and 
April, so that there appear to be at least two broods in a 
season. 
The pupa is concealed in the earth. 
The perfect’ insect appears from October till May. It 
seems to prefer cultivated districts, and is generally 
observed at rest on garden fences or tree-trunks. It also 
frequents flowers in the evening. 
SELIDOSEMA AMPLA. 
(Selidosema anpla, Huds. Ent. Mo. Mag. lix., 129.) 
(Platew ls fi258 (2h) 
This very broad-winged species was discovered by Mr. 
F. S. Oliver at Stoney Creek, near Glenorchy, at the head 
of Lake Wakatipu. 
The expansion of the wings is 18 inches. The fore-wings 
are very broad with the termen hardly waved and very oblique, 
pale brownish-ochreous strongly tinged with grey, with the prin- 
cipal veins broadly marked in ochreous; the first, median and
