New Zealand Lepidoptcra. 221 



streak along costa, in $ mixed with whitish, connected at hase with 

 a white longitudinal median streak reaching to f of disc ; two longi- 

 tudinal black streaks above and below middle, curved upwards 

 posteriorly, not reaching termen, upper interrupted near base and 

 more broadly posteriorly, lower indented above on veins, margined 

 beneath by a white streak curved up round its extremity, indented 

 beneath extremity of upper and continued round it to apex of wing ; 

 a slender dark grey terminal streak, in $ mixed with whitish : cilia 

 dark grey, more or less mixed with white, especially in $ . Hind- 

 wings blackish-grey, with faint pale post-median shade. 



Three specimens ; Seaward Moss, Invercargill. Allied 

 to N insignis, but very distinct. 



Notoreas mechanitis, Meyr. 



Three specimens sent of a well-marked local form 

 occurring on Mt. Holdsworth, Tararua Range, north of 

 Wellington, at 4000 feet, characterized as follows : 



25-27 mm. (typical form does not exceed 23 mm.) ; duller, with 

 less yellow intermixture ; specially characterised by the obsolescence 

 of the black lines on under-surface of hind-wings, which are strongly 

 marked in all South Island forms. 



Notoreas isoleuca, Meyr. (the locality for which should, I 

 am informed, be Castle Hill, not Wellington), is, as I am 

 now satisfied from further material, only a form of N. 

 mechanitis, the chief differences being due to a diminution 

 of the yellow suffusion. The species is however in all 

 its forms always quite distinct from N paradelpha, in 

 which the wings are differently formed, the fore-wings 

 being somewhat more elongate, with the costa straighter, 

 and the hind-wings obviously more elongate in proportion 

 to the fore-wings, the cilia sharply barred, the median 

 band of fore-wings narrower and differently formed, its 

 anterior margin much less curved, and posterior less 

 angulated in middle, and regularly indented above and 

 below middle. 



Notoreas ischnocyma, sp. n. 



Notoreas isoleuca, Huds., N. Zeal. Moths, 72, pi. viii, 

 27, nee Meyr. 

 <$ . 20 mm. Head and thorax dark fuscous. Fore-wings trian- 

 gular, costa slightly arched, termen obliquely rounded ; dark fuscous, 

 with some scattered yellow-whitish scales ; subbasal, first, median,
