The perfect insect appears in January, February and March. It frequents dry, open, sunny situations, generally alighting on paths or roads. It is also attracted by light. Genus 2.--THEOXENA, Meyr. "Palpi moderate, triangularly scaled, porrected. Antennæ in male bi-ciliated with long tufts of cilia (5). Fore-wings with vein 6 from below 9, 7 from angle of areole, 10 out of 9 above 7, 11 anastomosing shortly with 9, 12 free, closely approximated to 11 on areole. Hind-wings with veins 6 and 7 from a point or short-stalked, 8 free, closely approximated to 7 from base to near transverse vein."--(Meyrick.) We have one species. THEOXENA SCISSARIA, Gn. (_Panagra scissaria_, Gn., E. M. M. v. 43. _Theoxena scissaria_, Meyr., Trans. N. Z. Inst. xvi. 56.) (Plate VIII., fig. 41.) This delicate-looking species has occurred at Christchurch. The expansion of the wings is 1 inch. _All the wings are white. The fore-wings have a longitudinal, slightly curved black line, extending from a little beyond the base, almost as far as the termen below the apex_; above this line there is a black dot at about one-third; the apex of the fore-wing is slightly hooked, and there is a row of minute black dots on the termen of both fore- and hind-wings. The perfect insect appears in January. According to Mr. Fereday it frequents the plains near Christchurch, and towards the foot of Mount Hutt. Described and figured from a specimen in Mr. Fereday's collection. Family 4.--ORTHOSTIXIDÆ. "Hind-wings with vein 5 fully developed, rising from about middle of transverse vein, 8 connected with upper margin of cell by an oblique bar towards base."--(Meyrick.) (See Plate II., figs. 46 and 47.) This small family is represented in New Zealand by a single genus only. The peculiar oblique bar connecting vein 8 with the cell towards base, combined with the development of vein 5, distinguish it from all other families. If there is any chance of confusion with those forms of _Hydriomenidæ_ in which vein 8 is also connected by a bar (though in them the bar is placed beyond and not before the middle of cell), the absence of the characteristic areole of the _Hydriomenidæ_ will be a further test. Genus 1.--EPIRRANTHIS, Hb. "Face with appressed scales. Tongue developed. Palpi very short or moderate, porrected or subascending, rough-scaled. Antennæ in male evenly ciliated. Thorax rather hairy beneath. Femora glabrous; posterior tibiæ with all spurs present. Fore-wings with vein 10 anastomosing with 9, 11 anastomosing with 12 and 10 before 9. Hind-wings with 6 and 7 separate."--(Meyrick.) (Plate II., figs. 46 and 47, neuration of _Epirranthis alectoraria_; fig. 48, head of ditto.) Represented in New Zealand by two species. {80}EPIRRANTHIS ALECTORARIA, Walk.
