middle, in male obscure ; a curved transverse dark fuscous line near hind- 

 margin, often obsolete : cilia in male ferruginous mixed with dark fuscous, 

 in female reddish-ochreous, lighter towards tips. Hindwings dark fuscous- 

 grey ; with a dark fuscous line near base. 



Easily known by its ferruginous or reddish-ochreous colouring, which 

 in the female closely approaches that of the much larger (Ecophora 

 phegophylla. 



Lake Wakatipu, in December ; very common amongst Fagus solandn, 

 from 1,000 to 3,000 feet. 



55. Cremn. aphrontis, n. sp. 



Minor, alis ant. ochreo-flavis, partim griseo-suffusis, puncto disci nigro ; 

 post, saturate griseis, basim versus dilutioribus. 



Male, female. — 12-14^ mm. Head and palpi ochreous-yellow, anterior 

 edge of palpi suffusedly dark fuscous. Antennae blackish. Thorax dark 

 fuscous, with yellowish lateral and posterior spots. Abdomen dark grey, 

 posteriorly becoming whitish-ochreous. Legs dark grey, apex of joints 

 obscurely ochreous-whitish, posterior tibiae with very dense ochreous- 

 whitish hairs. Forewings moderate, costa moderately arched, apex round- 

 pointed, hindmargin very obliquely rounded ; grey, more or less wholly 

 suffused irregularly with ochreous yellow ; a blackish dot in disc beyond 

 middle : cilia pale ochreous-yellow, somewhat mixed with grey. Hindwings 

 grey, darker towards apex : cilia ochreous-whitish, suffused with dark grey 

 towards base. 



The irregular grey suffusion causes this insect to look like a yellow 

 species in bad condition. 



Arthur's Pass, in January ; common amongst the grass and rough 

 herbage, at about 5,000 feet. 



AppENDrx. 



A certain number of descriptions, probably referable to species of this 

 family, I have not been able to identify with any specimens in my posses- 

 sion. Some of these probably indicate good species ; others are so inade- 

 quate as to remain always unidentifiable. I give here a list of these, with 

 remarks ; the number prefixed to each is for reference in the index 

 only. 



56. Izatha attactella, Walk., Brit. Mus. Cat., 787. 



I noted this in the British Museum collection as apparently a new 

 species of Semiocosma. Large ; forewings whitish, irrorated with grey, 

 with a black longitudinal interrupted streak, some dark fuscous transverse 

 discal marks, and a row of black spots along hindmargin and apical third 

 of costa ; hindwings light grey.
