XV.—THE 
PROSELENA NIPHOSTROTA. 
(Prothelymna niphostrota, Meyr., Trans. N.Z. Inst. xxxix., 117.) 
(Plate XXII., fig. 14 @.) 
This species has occurred at Wellington, Dunedin, 
Clifden (Wallace), and Invercargill. 
The expansion of the wings is about 2 inch. The head and 
anterior portion of the thorax are white. The fore-wings are 
elongate, oblong, with the apex and tornus rounded and the ter- 
men oblique, white with dull chocolate brown markings consist- 
ing of @ basal patch covering the entire wing to about 4; a rhom- 
boidal patch on the costa at about 4 and a much smaller square 
spot at about #; a number of very irregular transverse bands on 
the dorsum extending from the basal patch to the tornus and 
half reaching to the costia; a small elongate-oval patch near the 
vermen below the apex and several minute terminal dots. The 
hind-wings are pale greyish-brown. 
Varies considerably in the extent and intensity of the 
brown markings which, in some specimens, are more or less 
tinged with grey. 
The perfect insect appears from December till March, 
and frequents forest or scrub. Although usually very rare, 
it sometimes occurs plentifully on the blossoms of the com- 
mon Veronca (V. salicifolia), which flowers during March 
and April. It flies freely soon after sunset. 
PROSELENA ANTIQUANA. 
(P. antiquana Walk., Cat., vol. xxviii., 307; maoriana, ib., 308; 
fusiferand, ib., 355; spoliatanda, ib., 356; vetustana, ib., 358; 
morosanda, 1b., 382; accensand, ib., vol. xxx., 983; Prothe- 
lymna nephelotana, Meyr., Trans. N.Z. Inst., xv., 57.) 
(Plate XLV., fig. 29 @.) 
This rather obscure, narrow-winged species has oc- 
curred at Wellington, Christchurch and Dunedin. It is 
evidently a local insect. 
The expansion of the wings is about $ inch. The fore-wings 
are elongate-oval with the termen oblique; brownish-ochreous 
dappled with numerous indistinct darker brown markings; there 
is a cloudy shading on the basal third of the costa and another 
shading on the apical half; four indistinct transverse lines before 
the middle; a pale reddish-brown patch in the dise and a series 
of dusky longitudinal streaks on the terminal area. The hind- 
wings are very pale whitish-ochreous with the veins very faintly 
marked in grey. 
Varies considerably in the distinctness of the mark- 
ings. 
The perfect insect appears from September till March, 
and may be looked for amongst serub, near the sea-coast. 
Deseribed and figured from a specimen in Mr. Phil- 
pott’s collection. 
Genus 2—PYRGOTIS, Meyr. 
Antennae in male moderately strongly ciliated. Palpi mod- 
erate, sub-ascending, second joint with rough projecting scales 
beneath and towards apex above, terminal moderate. Thorax with 
posterior crest. Fore-wings with veins 7 and 8 stalked, 7 to ter- 
men. Hind-wings with veins 3-5 separate, equidistant, rather 
approximated towards base, 6 and 7 short-stialked. (Plate E., figs. 
138, 14 neuration of Pyrgotis pyramidias; fig. 15 head of ditto.) 
We have three species in New Zealand and one species 
is known from Australia.

PYRGOTIS. PYRAMIDIAS. 
(Pyrgotis pyramidias, Meyr., Trans. Ent. Soc. Lond., 1901, 571.) 
(Plate XXIV., fig. 12 9.) 
This bright-looking little species has occurred on the 
Tararua Range in the North Island. In the South Island 
it has been found on the Mount Arthur Tableland, the 
Humboldt Range, and in the Routeburn Valley, near Lake 
Wakatipu, as well as at Otatara, near Invereargill. . 
The expansion of the wings is a little over # inch. The 
fore-wings are rather broad with the apex round-pointed and the 
termen strongly curved and very oblique; bright orange-yellow 
to bright orange-brown; there are sometimes a few obscure purp- 
lish-brown spots near the middle of the wing and always a very 
conspicuous triangular white spot placed obliquely on the dorsum 
at 4, with its longest side towards the termen; a small whiie 
mark near the tornus and several very minute white marks on 
the termen; there are usually four minute blackish or dark brown 
marks on the costa immediately before the apex; the cilia are 
orange-brown barred with darker brown. The hind-wings are 
shining white, sometimes with a few very faint grey spots to- 
wards the dorsum; the cilia are white. 
There is considerable variation in the depth of the 
eround colour of the fore-wings as well as in the presence 
or absence of the faint purplish-brown spots. The white 
markings are also somewhat variable in number, extent, and 
intensity. 
The perfect insect appears from October till February. 
It usually frequents beech forests, at elevations of between 
1,500 and 3,000 feet above the sea-level, and in certain re- 
stricted localities is very common. In the Routeburn Valley 
it occurs in great profusion amongst clumps of Polystichum 
vestitum. 
PYRGOTIS EUDORANA. 
(Pyrgotis eudorana, Meyr., Trans. N.Z. Inst. xvii., 1438.) 
(Plate Xcite si) a.) 
This handsome species has occurred in the North Island 
at Taranaki, Lake Horowhenua, Kaitoke and Wellington. 
It has not been recorded from the South Island at present. 
The expansion of the wings is slightly under } inch. The 
fore-wings are broad with the costa strongly arched, the apex 
somewhat acute and projecting, the termen curved and hardly 
oblique, deep purplish-brown,; there are two obscure darker 
oblique bands, one at about 4 and one at about 3, plainest on the 
dorsum; a conspicuous pale yellow or reddish-yellow apical patch 
with the veins and numerous short transverse lines sharply 
marked in reddish-brown. The hind-wings are bright ochreous- 
yellow clouded with grey towards the body. 
The perfect insect appears in December and February, 
and frequents forest. It seems to be a very rare insect. 
PYRGOTIS CONSENTIENS. 
(Pyrgotis consentiens, Philp., Trans. N.Z. Inst., xlviii., 421.) 
(Plate XLV., fig. 10 @.) 
This. rather lurid-looking little species was discovered 
by Mr. Philpott on Table Hill, Stewart Island, at an alti- 
tude of about 2,000 feet. It has also occurred on Mount 
Cleughearn, Hunter Mountains, at an elevation of about 
3,000 feet.
