P. despecta Wkr. (74 e) resembles the darker forms of the preceding species and is separated by the 
longer and narrower wings, smaller body and antennae, and the absence of certain apical spots. January, 
generally taken on the light. New Zealand, southern island (Christchurch, Otira River, Lake Wakatipu). 
P. fusca Pliilp. Thorax dark brownish ochre, abdomen grey. Porewing dark brownish ochre, the 
veins darker. A triangular white spot below x / 3 of the costal margin is edged with black below. An undulate 
irregular radial white stripe as far as before the centre of the wing, edged with a faded black colour. A 
white spot above the centre of the inner margin, edged below by a A-shaped line. A series of dark, light- 
edged spots extends from the costal margin near the apex to the anal angle, where they end with a A-mark. 
A series of dark, white-centred spots before the margin. Dark triangular marginal spots between the veins. 
Hindwing dark brown. The $ with an almost extinct marking and lighter ground-colour. A dark stripe below 
the costal margin from the base, and another stripe below it. A white spot in the centre of the wing. Hind¬ 
wing lighter than in the <J. 32—35 mm. Wakatipu District (New Zealand). 
P. descendens Huds. Similar to fusca. Body with reddish-brown hair. Forewing of £ rather broad, 
pale whitish ochreous with an irregular brown marking. Costal margin narrowly reddish-brown with a 
distinct subapical spot. A faded reddish-brown subcostal stripe extends from the base to % of the length of the 
body. A darker brown submarginal band encloses a few dark spots. A black streak at the cross-vein is distally 
edged with white. A very conspicuous black band above the inner margin is bent downward, finely edged 
with white towards the disc. A series of small blackish-brown spots within the submarginal band and below 
the apical spot. Marginal area spotted pale brown. Marginal spots light, centred dark. Hindwing dark brown. 
The $ is pale ochreous brown, the marking finer, less distinct. Submarginal band absent. 40—50 mm. 
Arthur Pass (New Zealand). 
P. autumnata Huds. Forewing intensely chocolate brown with a white and golden brown marking, but 
without a distinct radial streak. Oblong irregular white spots are at the origin of the veins 7—9. Six 
small spots follow behind them towards the margin. A large curved streak at the base of veins- 4—6, and 
3 triangular spots behind it. A few white spots behind the veins 2—4 near the base, and curved white mar¬ 
ginal spots between veins 2 and 8 . Nearly all the spots situate below the centre of the wing are edged with 
golden brown. Hindwing pale brown, somewhat diaphanous, the veins darker. $ 45 mm. Wellington. 
P. Oreas Huds. Forewing of $ chocolate brown, reddish towards the inner margin, with a white 
spot in the centre of the basal area. At the base below the middle there is an undulate black streak of 
about y 3 of the length of the inner margin, edged with white at the end above. 7 white, black-edged spots at 
the costal magin, one of them near the base, 2 before the centre, the 4 others near the apex in a row which 
is slightly bent downward. Indistinct dark spots before the margin, and a faded band before them. Ground- 
colour of $ redder. The marking smaller, more indistinct and edged somewhat red. Hindwing brownish-grey 
in both sexes, somewhat diaphanous. 45—50 mm. Mt. Egmont (New Zealand). 
P. gourlayi Philp. Antennae of serrate and finely ciliated. Thorax from pale to bright ochreous 
brown, abdomen greyish-brown. Forewing whitish ochreous brown to bright brown, with many dark brown, 
light-centred rings, the most conspicuous of which are: a somewhat triangular one in the centre of the wing 
and one or two others behind it. Moreover a spot at the costal margin near the base and one obliquely 
outwards below it. An indistinct dark submarginal shadow behind which a series of spots follows, and some¬ 
times also a series of spots before it. A blackish-brown band extends from the inner margin near the base 
nearly to the centre of the inner margin, dentate above and filled with whitish. Lunulate spots filled with 
dark are at the distal margin. Hindwing brownish ochre or grey ochre. Near oreas and descendens. q 34—38 mm. 
Mt. Arthur (New Zealand). 
P. ascendens Meyr. Body pale brownish ochre. Forewing pale bronze brown. An irregularly defined 
greyish-white wedge-shaped stripe below the centre of the wing from the base to % of the length of the wing, 
edged with blackish-brown above and in front. A submarginal row of white, dark-edged spots, and a similar 
row before it. The surroundings of the two rows are dusted greyish-white. Hindwing pale pinkish-grey, 
pale brown at the margin. $ 42—52 mm. Mt. Arthur. 
P. umbraculata Gn. (74 d). The most common Hepialida of New Zealand. Very variable in colouring 
and size (35—55 mm). Brownish-yellow, lighter or darker, a silvery white, dark-edged basal ray on the fore¬ 
wing is occasionally divided into 2 or 3 spots. Hindwing dull brownish ochreous, pink at the base. Distributed 
throughout New Zealand, from October to January, generally taken on the light. 
P. copularis Meyr. Thorax pale brownish ochreous, partly somewhat darker. Abdomen pale brownish 
ochreous, darker in the $ except at the anal tuft. Forewing similarly shaped as in umbraculata, but more con¬ 
cave at the costal margin. Forewing also pale brownish ochreous, darker in the $. A white, finely dark- 
edged spot in the centre of the wing at y 3 of its length. An oblong postmedian spot. A smaller spot is in 
the (J below the submedian fold between the two upper spots. An indistinct pale irregular transverse band 
at 2,3 0 f the length of the wing, sometimes strewn with dark scales and also with dark spots behind the 
band. Hindwing brown. 38—50 mm. Invercargill (New Zealand).
