The expansion of the wings is about 1½ inches. The fore-wings vary from very pale grey to dark blackish-grey; there is an obscure transverse line near the base, and another at about one-fourth; _the orbicular is oval and dark centred, the claviform is elongate, often very obscure, the reniform is broad dark centred, usually joined to the orbicular by a dark patch_; all the stigmata are outlined in black; beyond the reniform there is a rather jagged transverse line, and _several faint wedge-shaped markings_; there is a series of minute elongate black marks on the termen; the cilia are grey with three dark lines. The hind-wings are grey with several fine black marks on the termen; the cilia are white. This species seems to be rather variable both in ground colour and in markings. The perfect insect appears in October, November, December and January. It is not a common species. {32}AGROTIS CEROPACHOIDES, Gn. (_Agrotis ceropachoides_, Gn., Ent. Mo. Mag. v. 39; Meyr., Trans. N. Z. Inst. xix. 34.) (Plate VI., fig. 1.) This species has occurred at Rakaia. The expansion of the wings is 1½ inches. _The fore-wings are bluish-grey, dotted and streaked with darker grey; there are no distinct markings_, except an obscure transverse shading near the termen, and a series of dull terminal spots; _the costa is slightly concave_. The hind-wings are grey, paler towards the base, with a dark line on the termen; the cilia of all the wings are grey. The perfect insect appears in July, August and September. Described and figured from a specimen in Mr. Fereday's collection. Genus 11.--HELIOTHIS, Ochs. "Head rough-scaled; eyes naked. Antennæ in [M] ciliated. Thorax without crest. Abdomen not crested. Tibiæ spinose, anterior tibiæ with horny apical hook. "A rather small genus, but very generally distributed, though commoner in subtropical regions; it is a development of _Caradrina_; some of the species have a very wide natural range. The larvæ feed especially on the blossoms of their food-plants."--(Meyrick.) This genus is represented in New Zealand by the world-wide _Heliothis armigera_. HELIOTHIS ARMIGERA, Hb. (_Heliothis armigera_, Hb. _H. conferta_, Walk., Noct. 690. _H. armigera_, Meyr., Trans. N. Z. Inst. xix. 34.) (Plate V., fig. 40 [M], 41 [F].) This species has occurred plentifully at Waimarama (Hawkes Bay) and Wellington, in the North Island; and at Nelson, Blenheim, Christchurch, Rakaia, and Ashburton in the South Island. In Wellington it is certainly not so common as formerly, and Mr. Meyrick observes that its abundance is declining in some other localities also.
