diffused patch extending nearly to autimedial line, then out- 

 wardly oblique to hind margin near tornus, where it is edged 

 on each side by a white lunule ; subterminal line represented 

 by cin irregular row of black and white spots and a few 

 violet specks, nearly parallel with the postniedial shade; a 

 conspicuous round white marginal spot at IV, a white mar- 

 ginal streak in fold, and black, slightly pale-edged terminal 

 spots. 



Hind wing grey-brown with a cupreous gloss, paler at 

 base, with a pale postmedial line and a fine pale line at base 

 of fringe. 



Underside of fore wing and distal and costal areas of hind 

 wing shining gTcy-brown; a slightly crenulate, dark post- 

 medial line running across both wings from about two-thirds 

 costa of fore wing to near tornus of hind wing; four white 

 dots on costa of fore wing between postmedial line and apex 

 (less clearly visible above). Hind wing with basal inner 

 area paler, shading gradually to grey-brown ; a slight 

 brown lunule on DC^ and a very slight diffused subterminal 

 line.

 Also from Escourt, Natal, 1 $ in the British Museum. 

 Near P. limbirena, Gn., from which, however, it is easily 

 distinguishable by the following characters. The fore wing 

 is shorter on the apical half, the distal margin being slightly 

 angled at R^, instead of evenly curved, as in limbirena ; the 

 hind w ing is more smoky in tone than in limbirena, especially 

 on the basal area ; the pale marginal mark at R^ is a slight 

 pinkish streak extending to M' in limbirena, an almost 

 round white spot in cenescens ; and the shining bronze-gold 

 shades of cenescens are quite absent in limbirena, which is also 

 generally less black in its darker shades — altogether less 

 contrasted than (enescens.

 with dark brown ; collar with a fan of scarlet scales on
