Lake Wakatipu, 4,000 ft. (Hudson), in February ; one specimen. Allied 

 to siraea and aenea, but cannot be united with either ; doubtless the <£ , 

 as in those species, is very different, with dark hind wings. 



Oecophoridae. 

 Izatha metadelta Meyr. 



Mr. Hudson suggests that percnitis Meyr. is the $ of this species, and 

 on consideration of the available material, having now several specimens 

 of each form, all the pewnitis being <$ and all the metadelta $, I have no 

 doubt his view is correct, and they must be united as sexes. 



Glyphipterygidae. 

 Simaethis zomeuta n. sp. 



$. 18 mm. Head and thorax bronzy-brown, sprinkled with whitish. 

 Palpi with whorls of blackish white-tipped scales, base white. Antennae 

 dark fuscous dotted with white. Abdomen dark fuscous. Forewings 

 elongate, posteriorly dilated, costa gently arched, apex obtuse, termen 

 bowed, rather oblique ; bronzy-ochreous-fuscous ; some violet-white irro- 

 ration towards base and termen ; a moderately broad darker median 

 transverse fascia, angulated above middle, edged by obscure shades of 

 violet-white irroration, becoming more distinct on costa, where the second 

 forms a clear white oblique mark : cilia bronzy-ochreous, with two dark- 

 fuscous shades, and white patches on outer half above and below middle. 

 Hindwings bronzy-fuscous, becoming blackish on posterior half ; a rather 

 incurved white streak crossing dorsal half of wing from £ of disc to tornus, 

 and some whitish irroration between this and termen ; cilia whitish, basal 

 third dark fuscous. 



Mount Arthur, 4,600 ft. ; one specimen taken by myself in January t 

 not in fine condition, but twenty-five years have passed without further 

 captures. Near combinatana, but distinguishable by clear white streak of 

 hindwings, and the joints of antennae are relatively much more elongate 

 and slender. 



Simaethis ministra n. sp. 



S- 9 mm. Head dark fuscous, face sprinkled with white. Palpi 

 with whorls of dark-fuscous white-tipped scales, base white. Antennae 

 dark fuscous, shortly pubescent-ciliated. Thorax dark fuscous. Abdo- 

 men dark fuscous, segmental margins partially white. Forewings sub- 

 oblong, costa moderately arched anteriorly, apex obtuse, termen slightly 

 rounded, somewhat oblique ; dark bronzy-fuscous ; five very undefined 

 irregular transverse shades of white irroration, first three rather curved 

 or bent, fourth forming a clear white spot on costa beyond middle and 

 then a fine silvery quadrangular loop passing behind a transverse linear 

 discal mark of white irroration, fifth straight, interrupted above middle ; 

 two or three silvery-metallic scales before termen above middle : cilia 

 white with dark-fuscous shade (imperfect). Hindwings light fuscous, 

 becoming darker towards termen ; dorsal half with scattered white scales ; 

 a well-marked irregular white streak extending across dorsal half of wing 

 from disc at f nearly to tornus, its lower half approximated to termen ; 

 cilia white, with fuscous subbasal and post-median shades. 



Mount Holdsworth (Hudson); one specimen. This and the two fol- 

 lowing species are closely allied and very similar, agreeing together in
