joint ; second joint and tuft dark grej, becoming wliitisli towards 

 base and apex of joint, terminal joint anteriorly dark grey, 

 posteriorly wliitish. Antennae wliitisb. Thorax rather dark grey. 

 Abdomen whitish-ochreous. Anterior tibiae and tarsi dark grey ; 

 middle tibiae whitish with a broad dark grey band before apex, 

 tarsi dark grey with w^hitish rings at apex of joints ; posterior 

 tibiae and tarsi whitish. Forewings moderate, posteriorly dilated, 

 costa very slightly arched, apex strongly produced, acute, hind- 

 margin oblique, strongly concave ; snow-white ; all the veins 

 marked with thick cloudy dark fuscous lines, coarsely and suf- 

 f usedly on basal two-thirds, on apical third more sharply defined, 

 reaching costa, but terminating abruptly a little before hind- 

 margin ; a cloudy greyish-ochreous suffusion between the veins 

 towards hindmargin, ending abruptly with the veins a little 

 below costa, leaving a narrow clear white marginal streak ; space 

 beneath fold suffused with dark fuscous-grey, except towards 

 middle, and along inner margin from i to f ; an oblique cloudy 

 ill-defined fuscous-grey streak from costa at -} to middle of inner 

 margin, and a shorter similar streak from middle of costa to disc 

 at f from base ; a sharply defined blackish hindmarginal line : 

 cilia grey, mixed with grey- whitish. Hind wings with hindmargin 

 distinctly sinuate beneath apex ; pale ochreous-yellow, apex 

 slightly infuscated ; cilia yellow- whitish, with a suffused irregular 

 dark grey line near base. 



This very distinct and elegant species may be at once known 

 by the white groundcolour and dark veins ; in form it approaches 

 P. uncinella, but the apex of the forewings is more produced. 

 One of my specimens presents a curious deformity of venation on 

 one forewing only, vein 4 being furcate towards extremity, and 

 all the other veins being present, so that there are strictly 13 

 veins ; the wing is quite normal in form, but it cannot be regarded 

 as a natural variation ; the colouring follows the irregularity. 



Two specimens beaten from a Cupressus on the hills at 

 Murrurundi, New South "Wales, in November.
