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 1-3/8 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. {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.
