(Plate IV., fig. 21 [M], 22 [F].) This species has occurred commonly at Christchurch, Mount Torlesse, and Dunedin. The expansion of the wings is from 1-1/8 to 1-3/8 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.) (Plate IV., fig. 23 [F].) This rather striking insect has occurred at Napier and at Blenheim. The expansion of the wings is about 1½ inches. _The fore-wings are cream-coloured with the veins darker_; there are three faint black dots at about one-third, a curved series of black dots near the termen, _the termen itself being strongly shaded with dark greyish-brown_; the cilia are dark greyish-brown. The hind-wings are grey, paler towards the base; the cilia are also grey. Described and figured from a specimen in Mr. Fereday's collection. LEUCANIA UNIPUNCTA, Haw. (_Leucania unipuncta_, Haw., Lepidoptera Britannica, p. 174, No. 37. _Leucania extranea_, Gn., Noct. v. 77; Butl., Voy. Ereb., pl. ix. 2; Meyr., Trans. N. Z. Inst. xix. 12.) (Plate IV., fig. 24.) This species has occurred at Napier and at Wellington in the North Island. In the South Island it has been found at Nelson and at Christchurch. The expansion of the wings is 1¾ inches. The fore-wings vary from dull ochreous to bright reddish-ochreous; there are numerous indistinct blackish dots; _the orbicular and reniform are almost round and slightly paler than the rest of the wing; there is a minute white dot immediately below the reniform and an obscure, oblique blackish line from the apex of the wing_ ending in a series of minute black dots; _the termen is not indented_. The hind-wings are grey, darker near the termen; the cilia are white. Varies considerably in the ground colour and in the extent of the black speckling. "The larva is extremely variable. Its usual colour is pale brown with a white dorsal line and several dark lines on each side. {14}"Young larvæ closely resemble their food-plant in colour, and occasionally this is persistent throughout life; in fact the larva is very variable. Feeds on various grasses."[13]
