a strong sharply-defined black longitudinal mark in middle of 

 disc, its anterior extremity connected with an oblique dark fuscous 

 streak running to costa at one-third, and also produced a little 

 beneath towards inner margin ; above the black mark is a 

 suffused ochreous patch ; below it is a fuscous-grey cloud, 

 suffusedly continued to anal angle ; a cloudy fuscous-grey 

 triangular blotch on apical third of costa, from apex of which 

 proceeds a very irregularly waved cloudy-grey streak to hind- 

 margin above anal angle ; a small elongate cloudy-grey blotch 

 on middle of hindmargin : cilia whitish, basal third separated by 

 an interrupted dark fuscous line and barred with dark fuscous. 

 Hindwings fuscous grey ; cilia fuscous-grey, extreme tips and 

 base whitish. 



$. 11A-". Forewings with costa moderately arched near base ; 

 markings as in male, but the ochreous tints generally replaced 

 by grey, central black mark extremely slender, basal patch more 

 distinctly but very irregularly indicated. Hindwings slightly 

 paler than in male, spotted with darker. 



The narrowest-winged species of the genus, distinguished by 

 its ashy-grey tints and the ochreous cliscal patch of the male ; it 

 also has veins 6 and 7 of hindwings stalked, and therefore 

 approximates to Pyrgotis, but is too intimately allied to the 

 preceding species to be separated from it. 



Tolerably common and generally distributed ; I have usually 

 found it at rest on tree-trunks. It occurs at Sydney and Parramatta, 

 at Melbourne, and at Helidon in Queensland ; from September 

 to November. 



The types of Walter's descriptions quoted above are all 

 referable to this species ; that of Sciaph. rudisana is much worn, 

 the others are normal.
