Described and figured from a specimen in Mr. Fereday's collection.

{12}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 1-5/8 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 1-3/8 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.

LEUCANIA AROTIS, Meyr.

(Leucania arotis, Meyr., Trans. N. Z. Inst. xix. 11. Leucania aulacias, Meyr., Trans. N. Z. Inst. xix. 11.)

(Plate IV., fig. 18.)

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.
