This species varies slightly in the depth of its colouring.
The perfect insect is met with from January till March. On the Mount Arthur Tableland it occurred very commonly at about 3,800 feet above the sea-level. In this locality it was freely attracted by light, and large numbers of specimens were captured by the aid of a single candle, exhibited at the tent door during mild evenings.
LEUCANIA ACONTISTIS, Meyr.
(Leucania acontistis, Meyr., Trans. N. Z. Inst. xix. 9.)
(Plate IV., fig. 14.)
A single specimen of this species was captured at Castle Hill by Mr. J. D. Enys, and is now in Mr. Fereday's collection.
The expansion of the wings is 1⅜ inches. The fore-wings are dull ochreous; the veins are slightly darker; there is a fine, black, doubly-curved, longitudinal streak from the base to about one-third. The hind-wings are pale yellowish-grey. The cilia of all the wings are dull ochreous.
Described and figured from the specimen in Mr. Fereday's collection.
LEUCANIA PHAULA, Meyr.
(Leucania phaula, Meyr., Trans. N. Z. Inst. xix. 10.)
(Plate IV., fig. 15.)
Two specimens of this insect, "bred from tussock grass," were found at Christchurch.[11]
The expansion of the wings is 1½ inches. The fore-wings are dull ochreous, with the veins obscurely indicated by black and white dots; there is a curved series of minute black dots near the termen. The hind-wings are pale ochreous, clouded with grey towards the termen. The cilia of all the wings are dull ochreous. This insect may be distinguished from Leucania unica by its larger size, duller coloration, less oblique termen of fore-wings, and simple antennæ in the male.
The perfect insect appears in November.
Described and figured from a specimen in Mr. Fereday's collection.
LEUCANIA ALOPA, Meyr.
(Leucania alopa, Meyr., Trans. N. Z. Inst. xix. 10.)
(Plate IV., fig. 16.)
This species has occurred at Lake Coleridge and at Lake Guyon.
The expansion of the wings is about 1½ inches. The fore-wings are dull orange-brown; there are three obscure black dots at about one-third; the reniform is represented by a rather conspicuous cloudy spot; there is a curved series of black dots near the termen. The hind-wings are grey, paler towards the base. The cilia of all the wings are dull orange-brown.
The moth appears in March.
Described and figured from a specimen in Mr. Fereday's collection.
LEUCANIA MICRASTRA, Meyr.
(Leucania micrastra, Meyr., Trans. Ent. Soc. Lond. 1897, 383.)
(Plate IV., fig. 10.)
Three specimens of this insect have occurred in my garden at Karori.
The expansion of the wings is 1⅝ inches. The fore-wings are bright orange-brown; there are several white scales near the base, two black-edged white dots at about one-third, a small black spot with a shining white dot on each side of it at the origin of veins 3 and 4, and a series of black and white dots on all the veins near the termen; the cilia are orange-brown tipped with white. The hind-wings are pale ochreous-brown. The cilia are ochreous broadly tipped with white.
This species somewhat resembles Leucania alopa in general appearance, but the wings are narrower and the colour of the fore-wings is considerably brighter.
The moth appears in December.
LEUCANIA UNICA, Walk.
(Leucania unica, Walk., Noct. 112; Butl., Voy. Ereb., pl. ix. 9. Nonagria juncicolor, Gn., Ent. Mo. Mag. v. 2. Leucania unica, Meyr., Trans. N. Z. Inst. xix. 10.)
(Plate IV., fig. 17.)
This insect has been taken at Blenheim and at Rakaia.
The expansion of the wings is 1⅜ inches. The fore-wings are dull ochreous with the veins darker; there are one or two obscure blackish dots at about one-third from the base, and several faint dots near the termen. Hind-wings paler with very pale cilia; the antennæ in the male are moderately bipectinated.
The moth appears in November.
Described and figured from Mr. Fereday's specimens.
LEUCANIA AROTIS, Meyr.
(Leucania arotis, Meyr., Trans. N. Z. Inst. xix. 11. Leucania aulacias,[12] Meyr., Trans. N. Z. Inst. xix. 11.)
(Plate IV., fig. 18.)
This species has occurred at Wellington in the North Island. In the South Island it has been found at Blenheim, Christchurch, and Rakaia.
The expansion of the wings is about 1½ inches. The fore-wings are cream-colour with the veins finely marked in grey; there is a series of streaks of darker cream-colour between the veins, and a row of minute black dots near the termen; the cilia are cream-colour. The hind-wings are dark grey with the cilia white.
The perfect insect appears in November and December. It is rather a scarce species.
LEUCANIA SULCANA, Fereday.
(Leucania sulcana, Frdy., Trans. N. Z. Inst. xii. 267, pl. ix.; Meyr., Trans. N. Z. Inst. xix. 11.)
(Plate IV., fig. 19 ♂, 20 ♀.)
This species has occurred at Akaroa and at Dunedin.
The expansion of the wings is from 1½ to 1¾ inches. The fore-wings are light ochreous with the veins white; there is a shaded, brownish, longitudinal streak near the apex, another from the end of the cell to the termen, a stronger streak from the base of the wing to near the tornus, and another along the dorsum; there is a minute black dot near the base above the middle, a slightly larger dot at about one-third, a conspicuous dot between the origins of veins 3 and 4, and a very minute dot on vein 6. Hind-wings dark blackish-grey, cilia paler.
The perfect insect appears in February, and has been taken at sugar.
Described and figured from specimens in Mr. Fereday's collection.
LEUCANIA SEMIVITTATA, Walk.
(Leucania semivittata, Walk., Suppl. 628; Meyr., Trans. N. Z. Inst. xix. 12.)
(Plate IV., fig. 21 ♂, 22 ♀.)
This species has occurred commonly at Christchurch, Mount Torlesse, and Dunedin.
The expansion of the wings is from 1⅛ to 1⅜ inches. The fore-wings are pale ochreous; there is a very obscure, shaded, brownish, longitudinal streak below the middle, a conspicuous black dot at the base, a second at about one-sixth, a third at one-third, a fourth between the origins of veins 3 and 4, a curved series of minute terminal dots. Hind-wings much paler with a darker blotch near the middle. In the female the wings are browner with the dots much smaller or absent.
The moth appears in April and May, being found at night on the blossoms of the scabious.
Described and figured from specimens in Mr. Fereday's collection.
LEUCANIA BLENHEIMENSIS, Frdy.
(Leucania blenheimensis, Frdy., Trans. N. Z. Inst. xv. 196; Meyr., ib. xix. 12.)
