262 DB. A. G. BUTLER ON LEPIDOPTEBA [Mar. 19, 



A. acrita and A. imdorina, Stand. : the latter therefore can only 

 be regarded as an imperfectly isolated race of A. acrita. 



45. AcBJEA, sp. inc. 



A somewhat melanistic female specimen, having the primaries 

 very like A. acrita on both surfaces ; but the pattern and color- 

 ation of the under surface of the secondaries curiously like 

 A. armcreon, with the central rosy band well developed. It would 

 be rash to describe it on this single example, without carefuUy 

 studying the whole of the species, as it may prove to be an 

 aberrant example of some described species ; but, so far, I have 

 failed to identify it. At first I supposed it to be the female of 

 M. Oberthiir's A, cJueribuIa, but a careful comparison with the 

 male of that species proves clearly that it is distinct.

48. Almsa aueantiaoa, sp. n. (Plate XV. fig. 4.) 



Bright orange above; the cell of primaries black, leaving a 

 triangular subbasal spot and a quadrate subterminal spot of 

 orange ; costal border black, with a fine basal orange streak ; base, 

 nervures, one or two spots near the base below origin of first 

 median branch and internal border black ; external border rather 

 more broadly black, widest at apex, its inner edge siuuated between 

 the nervures ; base of the secondaries occupied by a broad irregular 

 black blotch ; a black spot on upper discocellular ; veins partly 

 black, outer border broadly black : body black ; collar tufted at the 

 sides with orange ; abdomen orange at the sides. Under surface 

 with the black slightly more restricted than above, the costa of 

 primaries streaked with ochreous, the outer border interrupted by 

 two rows of cream-coloured spots, the inner row irregular, 

 abbreviated, consisting of five oval spots, the outer regular, of 

 seven : secondaries — the basal black patch interrupted by two rows 

 of creamy spots, the inner consisting of four, the outer of two 

 spots ; external border enclosing two series of eight creamy-white 

 spots : body black, legs and sides of abdomen orange. Expanse of 

 wings 34 millim. 



Two examples (one much damaged), Fwambo. 



In the pattern of the upper surface this pretty little species is 

 nearest to A. amazoula, but the under surface more nearly 

 approaches A. interposita.
