100 Mr. H. Eltringham's Monograph of the 



Underside. F.-w. Rose pink. A minute white dot near base 

 above costal. Black markings as on upperside but apical and 

 marginal border much reduced. Subapical area bluish white 

 wiih elongated triangular internervular orange marks. H.-w. 

 Basal black very sliarply defined and spotted with white as in 

 previous forms. Broad black marginal border with medium- 

 sized internervular white spots, a white sulmiarginal streak in 

 lb, and la. Discal area pinkish white bordered basally and 

 distally with red internervular marks. Fringes in both wings 

 spotted with white. Thorax sooty black with two or four white 

 spots above and many below. Abdomen black above, to near 

 extremity, remainder deep orange. 



$. Resembles ^ but f.-w. brownish ochreous, and basal 

 black much reduced in areas la and lb, hind-marginal border 

 much narrower. H.-w. rather duller than in ^. Underside 

 with ground-colour of apical area of f.-w., and discal area of 

 h.-w., creamy white. H.-w. hind margin spots creamy white 

 and larger. Abdomen, and in some cases thorax, reddish ochreous. 

 Dorsal thoracic spots more conspicuous. 



Some 9 examples are much paler and lack the discal spots 

 in f.-w. An example of this kind before me is almost indis- 

 tinguishable from some specimens of A. anemosa. 



That wehuitschii and anemosa are really different species 

 seems to me extremely doubtful. Series of prepara- 

 tions of the genitalia show that, allowing for a narrow 

 limit of individual variation, there is little or no constant 

 difference. In the $ genital plate there is a small but 

 noticeable difference, those of wclwitschii and alhoradiata 

 being alike and differing slightly from that of anemosa. 

 With our present conception of species-f )rmation it is 

 inevitable that we should occasionally find forms which 

 are so near to the line of specific distinction that we 

 cannot say with certainty, on which side tliey lie. Mean- 

 while I have kept anemosa separate from wehoitschii, though 

 it matters little whether we regard them as specifically 

 distinct or not. 



A single $ from Angollo (Angola) in the Tring collec- 

 tion is intermediate between welwitschii and alhoradiata 

 and has a white mark in area lb of £-w. 



Neither Aurivillius' description nor figure of wehvitschii 

 quite agrees with the original reference of Rogenhofer. 

 That author describes the $, and I have been fortunate 

 enough to obtain a cotype from amongst the Felder
