478 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



ochreous, with a dark fuscous line near base. Hind wings pale 

 grey spotted with darker ; cilia pale grey, darker towards base. 



Variable in size, as well as in intensity of colouring ; but well 

 characterised by the remarkably elongate and narrow forewings, 

 with costa hardly arched, and the ochreous-brown tint of the 

 ground-colour is also a constant point of distinction. 



Taken commonly at Blackheath in the Blue Mountains (3,600 

 feet), and also occurs at Nowra, on the Shoalhaven Eiver, 

 and occasionally near Sydney ; it is plentiful near Melbourne ; 

 in low heathy scrub, from January to March. 



10. Dich. atristrigana, n. sp. 



<$ ? . 5$" -6j". Head, palpi, antennae, and thorax dark fuscous. 

 Abdomen fuscous-grey. Legs ochreous-whitish, anterior and 

 middle tibiae and tarsi suffused above with dark fuscous. Fore- 

 wings moderately elongate, somewhat dilated, costa moderately 

 arched, hindmargin very oblique ; greyish-fuscous or dark 

 fuscous ; costa and inner margin coarsely strigulated with black ; 

 an oblique black streak from one-fourth of inner margin, reach- 

 ing half across wing ; a short black longitudinal streak in middle 

 of disc, both extremities generally somewhat turned upwards so 

 as to appear somewhat crescentic in form, sometimes connected 

 with oblique dark shades from costa ; a blackish elongate oblique 

 mark above anal angle : a slender black streak along hindmargin 

 from apex : cilia light ochreous-brown, paler towards anal angle, 

 indistinctly barred with blackish, and with a black line near base 

 along hindmargin. Hindwings light grey spotted with darker ; 

 cilia pale grey with a darker line near base. 



Nearest to D. solana in form of wing, but costa more evenly 

 arched, and hindmargin more oblique ; distinguished by the dark 

 colouring and black marks, especially the longitudinal discal 

 streak, which is however variable. 



I took four specimens flying in the evening amongst open scrub 

 near Parramatta, New South Wales, in March.
