152 RHOPALOCERA AFRICA AUSTRALIS. 



a row of white spots near and parallel to hind-margin, 

 arranged in pairs on each nervule ; fringe conspicuously 

 marked with white in hollows of sinuate margin. UNDER- 

 SIDE. Olivaceous-brown, rather glistening ; with white bands 

 and spots. Fore-wing : white band, from about middle of 

 costa, extending to just above anal angle ; white spots near 

 apex distinct ; spots that on upper-side edge the violet space, 

 near hind-margin, larger than above ; before white band, the 

 ground-colour is darker ; a few small, white spots near base. 

 Hind-wing : white, transverse band continued narrowly to 

 apex ; each spot in the row running parallel to hind-margin 

 divided into two parts. 



? . Similarly marked ; white bands much broader and 

 more conspicuous, and only narrowly bordered with greyish- 

 blue. UNDER-SIDE. Quite similar to that of $ . 



This splendid species of Diadema has long been known as an inhabitant 

 of Tropical West Africa. It was first discovered as a native of extra- 

 tropical Southern Africa by the French traveller Delegorgue, as noted in 

 the Appendix to his work, "Voyage dans L'Afrique Australe," by M. 

 Boisduval.

$ . Black ; with large patches of iridescent white. Fore- 

 wing : an elongate, more or less distinct, longitudinal white 

 streak in discoidal cell ; a broad, oblique, white stripe, beyond 

 middle, from costa, crossed by three nervules, almost entirely 

 separates apical portion from rest of wing ; a large, somewhat 

 semi-circular, white blotch occupies nearly the whole of inner- 

 margin, rising as far as median nervule. Hind-wing: iridescent 

 white ; basal portion blackish ; a broad, black band along 

 hind-margin, radiating in streaks between nervules. UNDER- 

 SIDE. Paler ; similar in pattern. Fore-wing : a small white 

 spot at base ; another on costa, near base ; a third in discoidal 

 cell, before the white streak ; costa tinged with ochreous- 

 brown, as well as apical portion beyond oblique white band. 

 Hind-wing: hind-marginal band coloured with ochreous-brown, 

 much narrower than on upper-side^ radiating very distinctly 

 between nervules. On both wings are the traces of a double 

 row of minute, whitish lunules, along hind-margin. 



In some West African specimens, the iridescent light forms 

 a bluish bordering to the white markings; and the hind-
