490 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



nected with, the triangular costal patch by a slender cloudy streak ; 

 an obscure dark fuscous mark on hindmargin above middle : 

 cilia light brownish-ochreous or fuscous-grey, with a dark fuscous 

 line. Hindwings whitish-grey tinged with ochreous, thickly 

 spotted with dark grey, apex dark grey ; cilia grey-whitish, with 

 a dark grey line near base. 



Nearly allied to C. spurcatana, but the forewings are not 

 posteriorly dilated in the male, the groundcolour is more greyish 

 and less ochreous, there is no conspicuous dark oblique streak from 

 inner margin near base, and the dark markings from costa are 

 mixed with reddish towards disc. The female is rather lighter 

 and less strongly marked than the male. 



I have four specimens (three males, one female) taken amongst 

 forest growth near Dunedin, New Zealand, in January. Walker's 

 types are from Auckland. 



5. Oac. cuneigera, Sutler. 

 (Term cuneigera, Butler.) 



10". Head and thorax light grey ; palpi rather elongate. Fore- 

 wings moderately broad, somewhat dilated posteriorly, costa 

 gently arched, hindmargin sinuate, not oblique ; whitish-grey, 

 clouded with darker along inner margin and more strongly along 

 hindmargin ; a large sharply-defined blackish-grey costal tri- 

 angular blotch, extending on costa from one-fourth nearly to 

 apex, and reaching more than half across wing. Hindwings 

 grey spotted with darker. 



A very distinct species, separable from all by the large clearly- 

 marked dark triangular blotch on costa. 



I am only acquainted with Butler's type, which seems to be 

 referable to this genus, as far as I can judge without complete 

 investigation ; the above diagnosis is drawn from it. 



6. Cac. biguttana, Walk. 

 (Teras liguttana, "Walk., Brit. Mus. Oat. 305).
