A. natalica natalica. It is a matter of some difficulty 

 adequately to describe this species owing to its extreme 

 variability. It is however abundant and widely distributed, 

 and familiarity with its general appearance is easily attained 

 by reference to the long series to be found in most collec- 

 tions. Average examples may be described as follows : — 



(J. Expanse 50-80 mm. F.-w. rosy red to pinkish ochreous, 

 subapical area deep oclireous. A basal black suffusion extending 

 nearly to middle of cell, Costa very narrowly black. Apex 

 black (3-4 mm. wide), becoming very narrow at 4 and con- 

 tinued as a fine marginal line to hind angle. Black spots 

 variable. When all present arranged as follows : — One in cell at 

 or just before origin of 2, a double spot on upper part of dis- 

 cocellulars. Just beyond cell a discal row of confluent spots 

 widest near costa and extending to nervule 4, and forming 

 together a characteHstic ivedcje-shaped marh. A submarginal 

 row of three spots in 3, 2 and la. A spot near Imse of 3 in line 

 with, but separated from, the wedge-shaped row. A similar spot 

 near base of 2 well separated from the neighbouring nervules. 

 Immediately beneath this a spot in la, and in the same area 

 another spot at the edge of the black basal suffusion. 



H.-w. with a black basal suffusion extending nearly to middle 

 of cell, and a black hind-marginal band with a very faint 

 indication of paler internervular marks. This band varies in 

 width from about 2-4 mm. Tlie discal and Imsal spots are 

 always small, and while corresponding to those on the underside, 

 are in many cases only faintly indicated. 



Underside. F.-w. ground-colour as on upperside but paler 

 and duller. The black basal suffusion only shows through from 

 the upperside and the apex is greenish- ochreous with orange 

 internervular marks, the margin being narrowly black. Two 

 black spots at base of costa, remaining spots as above but those 

 just beyond cell more distinctly separated. 



H.-w. ground-colour pinkish ochreous. No basal suffusion. 

 A hind-marginal band formed of large pale sage-green spots 

 surrounded by heavy black arches and a black marginal line. 

 In area lb there is a marginal line of the same colour as the 

 spots. About the base, inner margin, and along inner edge of
