 A. oreas oreas. 



(J. Expanse 48 to 58 mm. F.-w. much angulated and hind 

 margin markedly convex. Black with large lemon yellow 

 spots.* Of these there is one in cell extending from subcostal 

 to median and lying between origin of 2 and 3. A subapical 

 band of three in 6, 5, and 4, the last somewhat more distally 

 placed, one in 2 not quite touching- the median, and beneath it 

 and nearer margin a spot in lb. Usually a small yellow streak 

 near base of lb close to median. 



H.-w, black with a central lemon yellow patch of peculiar 

 shape. This patch occuj^ies the basal portion of 7, nearly the 

 whole of cell except a small streak on lower side at base, and 

 extends beyond cell slightly into 6, 5, 4, 3, and 2. 



Underside. F.-w. Costa dark to pale reddish brown. Yellow 

 spots as on upperside but paler. From base to subapical spots 

 brown-black, base of cell and the edges of median nervure 

 and its branches laterally dusted with large yellowish scales. 

 Apical and hind-marginal Ijorders in some cases also brown- 

 black but more usually reddish brown to brownish ochreous 

 striated by the black nervules and internervular rays. 



H.-w, varying from black-brown to reddish ochreous, A 

 central yellow patch as above but paler and usually extending 

 in a narrow suffused streak across areas Ic, and lb, near their 

 middle. Area 8, a streak on lower side of base of cell, and 

 basal part of Ic, lb, and la more distinctly reddish than 

 remainder of ground-colour. A small black spot in 8, rarely 

 one near base of cell, two in Ic (the second on the inner edge 

 of extension of yellow patch) two in lb and usually one in la. 

 Outer half of wing striated by black nervule ends and inter- 

 nervular rays, 



* Miss Sharpe's figure shows yellow spots in f.-w^, whilst her descrip- 

 tion states that they are white. I liave, liowever, examined tlie ty]>e 

 in the Jackson collection, and it has yellow spots agreeing with the 

 figure.
