easily recognised. Its nearest ally is probably A. Satis, Ward, also a native of 
East Africa ; but this species differs markedly in possessing two conspicuous 
white spaces in the fore-wing and an irregular transverse double row of black 
spots in the hind-wing. In the Hewitson Collection in the British Museum i 
there is another allied species (unnamed) labelled " Zanzibar ; " but in this 
butterfly the wings are only semi-transparent and warm reddish-ochreous, and 
the fore-wing has a conspicuous large black spot in the discoidal cell and a 
dusky hind-marginal border enclosing six or seven large spots of the ground- 
colour. 
The late Mr, Monteiro informed me that he met with A. Babhaioe not 
uncommonly at Delagoa Bay, but that it was not easily captured owing to its 
high flight. j

J Semi-transparent ; hrick-red with black spots ; the apical portion 
of forc'ioing transpa.rent ashy-grey. Fore-iving : base narrowly suffused 
with black ; red ground-colour abruptly and irregularly bounded by 
the apical grey in an oblique line from costa beyond middle to end of 
first median nervule ; an oblique irregular black streak closing dis- 
coidal cell ; in some specimens a small more or less distinct spot in 
cell near its extremity ; occasionally a small blackish spot beneath cell, 
between first and second median nervules ; more rarely another small 
spot nearer base, a little below median nervure ; along hind-margin a 
row of six more or less defined inter-nervular red spots, of which the 
first and second, next apex, are larger and more elongate than the rest. 
H'mcl-iving : all brick-red ; a conspicuous basal black patch, formed of 
three or four confluent large spots ; a separate spot close to costa near 
base ; two spots marking extremity of discoidal cell, and another near 
them in the cell ; a discal row of eight spots from costa to inner 
margin, highly irregular, the outermost spot being that immediately 
above third median nervule, and the spots between it and inner margin 
larger and less rounded than the others ; a hind-marginal black border
