A NOTE ON SOME AFRICAN RHOPALOCERA. 75 



This, the commoner species by far, hardly needs description. 

 The male is excellently figured by Dixey {I. c), the female by 

 Butler {l. c), whilst Eltringham very accurately describes both 

 sexes and figures the genitalia of the male. 



The species may be separated at a glance by the undersides of 

 the hind wings. In ^4. miranda there is a broad, sharply defined 

 whitish band beyond the central band ; this is absent in A. 

 niirabilis, the buffy marginal area only being separated from the 

 central band, by a diffuse, clear white area broadest in inter- 

 spaces 4 and 5. 



There are numerous other differences. The blackening of 

 the extremities of the veins is much heavier in A. miranda ; the 

 hind marginal borders of both wings broader ; the inner line of 

 border of hind wing underside is formed of a series of crescents 

 in A. miranda, whilst it is an even, continuous line in A. niirabilis ; 

 the black shade beyond the pale sub-apical patch of fore wing is 

 obsolescent in A. miranda, and the general coloration richer and 

 darker. 



The genitalia of the males are quite distinct. A. mirabilis 

 lias a long, straight penis and ventral " keel " and a simple 

 uncus ; A. miranda a sickle-shaped penis, a short ventral " keel " 

 or vinculum and a bifid uncus. 



Length of fore wing 2'25 cm. 



B.M. Type No. Rh. 048, ? . " More than 80 miles south of 

 Berbera, Somaliland, Thrupp." 



This is Butler's type of A. mirabilis, 2 . 



The species would appear to belong to the interior plateau and 

 the highlands of Somaliland, whence came Butler's female type 

 and the specimens mentioned by Dixey {l. c). Further south 

 Selous obtained another form of the female. 



A. miranda, ? - f. selousi, nov. 



? . Differs from typical A. miranda, female, by being of a 

 general dirty, translucent, pale grey-brown coloration; dark 

 markings as in typical form, but grey, not black. Below, the 

 central transverse band of hind wing broader, and the light band 

 succeeding it pale yellow. 



Length of fore wing 2"6 cm. 



B.M. Type No. Pih. 049, ? , labelled " E. Africa, Namanga, 

 12:ii:'16, P. C. Selous," but most probably obtained during 

 February, 1912, between Lake Baringo and Lorian Swamp, 

 British East Africa. 



There are three females in the Museum of this form, and 

 three males from same locality, which, however, do not appear 

 to be separable from typical males of A. miranda.
