margin ; costa black from base to beyond middle, at first very narrowly, 

 but shortly dilating to form a triangular sharply-defined patch, of which 

 apex is in middle of disc ; claviform dot-like, black, or sometimes obsolete ; 

 reniform 8-shaped, obscurely outlined with blackish ; second line not paler, 

 but distinctly dark-margined, somewhat bent but hardly sinuate ; a row of 

 black dots immediately before hindmargin ; cilia grey- whitish, with a grey 

 basal line. Hindwings 1J, in male whitish, in female very pale whitish- 

 grey ; postmedian line and hindmargin very faintly greyer ; cilia whitish, 

 with a faint grey line. 



Very distinct by the peculiar black costal marking. Felder's figure is 

 very coarse, but indicates this correctly. 



Makatoku and Dunedin, amongst forest, in March ; five specimens. 

 32. Sco23. melancegis, n. sp. 



Male, female. — 22-23 mm. Head and thorax ochreous mixed with 

 whitish, shoulders suffused with dark fuscous. Palpi 2 \, dark fuscous, apex 

 whitish, basal joint white. Antennae grey. Abdomen ochreous-grey- 

 whitish. Legs white irrorated with dark fuscous, tibiae and tarsi banded 

 with dark fuscous. Forewings elongate, triangular, costa slightly arched, 

 apex rounded, hindmargin slightly sinuate, oblique ; pale fuscous, very 

 densely irrorated with black ; a whitish streak from base to inner margin 

 at i, beneath which the black suffusion is obsolete ; an obscure dentate 

 irregular whitish transverse line a little before first line, between which and 

 first line the ground colour is mixed with pale yellow ; first line slender, 

 white, almost straight, oblique, not reaching inner margin, but continued 

 near and parallel to it to meet second line, which is also narrow, sharply 

 defined, and does not reach inner margin ; reniform somewhat 8-shaped, 

 narrow, clear white ; space included between a straight line passing through 

 anterior edge of reniform and blackish margin of second line suffused with 

 white ; inner margin from before first line to anal angle suffused with pale 

 yellow ; veins in terminal space more or less indicated with yellowish ; 

 subterminal line cloudy whitish, rather broad, obscurely interrupted, hardly 

 touching second line ; a waved white hindmarginal line : cilia whitish, 

 basal third barred with dark grey, with a grey posterior line. Hindwings 

 11, very pale whitish-grey, faintly ochreous-tinged ; postmedian line and 

 hindmargin obscurely darker grey ; cilia white, with a grey line. 



The blackish suffusion appears to form a very large blotch on costa 

 beyond first line, nearly reaching to inner margin ; this distinguishes the 

 species from all others. 



Arthur's Pass (1,700 to 2,600 feet) and Lake Wakatipu (4,200 feet), 

 frequenting rocks in sheltered situations or amongst bush, in December and 

 January ; rather common.
