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. 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. {13}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 [M], 20 [F].) 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.
