 The ^ further differs from the $ in having the fore-wing 

 more pointed at tlie apex and more prominent at the 

 middle of the hind-margin, and the terminal joint of the 

 palpi longer, more slender, and more acuminate. 



Deloncura can no longer be held as an endemic South- 

 Afiican genus, two Tropical-Afiican congeners being now 

 known, one from Kinsembo, on the coast of North Angola, 

 and the other from Kisumu on the N.E. shore of Victoria 

 Nyanza. These two species have been constituted as a 

 new genus, FuuUooiia, hy Mr. S. A. Neave (Novit. Zool, xi, 

 1904, pp. 336-37) ; but now that both sexes of Beloneura 

 are forthcoming, it is unquestionable that Poidtonia is in 

 all respects structurally inseparable from the older genus. 

 It is noteworthy that these two tropical species, coming 

 from such widely-separated localities, are not only closely 

 related, but that in pattern and marking they are both 

 much nearer to the Natalian D. millari here described 

 and figured than to the unicolorous D. immaculata from 

 Kaffraria. They difier from D. millari in possessing a 

 fuscous-brown apical-hind-marginal border on the upper- 

 side of the hind-wings, broader in the Angolan D. barca 

 (H. G. Smith)* than in the Victoria-Nyanza D. ochrasccns
