wings in male ochreous-yellowish, posteriorly suffusedly spotted 

 with grey, and with a large irregular black blotch at base, cilia 

 whitish, becoming grey at apex, with a darker grey basal 

 line : in female light grey, darker posteriorly and spotted with 

 darker, cilia light grey. 



The male is immediately distinguished by the peculiarly 

 coloured hindwings, which are unique in their way ; the female 

 is more cafficult of definition, but may be known from D. monti- 

 vagana by the broader f orewings, more arched costa, and distinct 

 basal patch ; from D. atristrigana by the rather lighter colouring 

 and the absence of the black markings ; it approaches very nearly 

 D, hyperetana, but is larger, rather broader- winged, with the costa 

 slightly more arched, and the markings less obscure, 



Common, and often taken at rest on fences near gardens ; it 

 occurs at Sydney, Bulli, and Parramatta, in New South Wales ; 

 at Melbourne ; and at Brisbane and Rosewood, in Queensland ; 

 from August to October, and in December and April.

 fuscous ; a small cloudy fuscous spot on inner margin before 

 middle ; an oblique rather narrow dark fuscous fascia from before 

 middle of costa, reaching only half across wing, rarely obscurely 

 produced to inner margin before anal angle, in which case its 

 outer edge is semicircularly excavated in middle ; an indistinc^ 

 triangular d^rk fuscous patch on costa at three-fourths ; an 

 obscure triangular dark fuscous blotch on middle of hindmargin ; 

 all these markings vary in intensity and are often obsolete : cilia
