tusa and -S^. motozi in South Africa ; S. pertusa var. and 8. eliminata 

 in British East Africa at the same spot ; we have S. pertusa from 

 Aden, and S. eliminata from Ahyssinia. Altogether these forms 

 do not look like good distinct species.

117. PxEGtrs BETTOifi, sp. n. (Plate XXXII. fig. 1.) 



Nearest to P. zebra and P. asteroclia, but not very closely allied 

 to any African species known to me, and on the upper surface 

 somewhat resembling the Xew-World P. asychis. Upper surface 

 black-brown ; a vrhite spot near the base of each discoidal cell ; a 

 central interrupted white belt, not reaching the borders of the 

 wings, commencing with a subcostal dot on the primaries, where it 

 is divided into three quadrate spots by the first and second median 

 branches, oblique and terminating in a subconfluent dot on the 

 secondaries ; a transverse trifid subapical white bar on the pri- 

 maries, and a single small spot on the second median interspace ; 

 submarginal series of dots unequal, the first, second, and fifth 

 extremely minute ; in the secondaries the first, fourth, fifth, and 

 sixth extremely minute ; fringe white, varied with blackish at the 

 extremities of the veins : body normal. Primaries below dark 

 greyish, but with the usual copper-brown reflections ; white spots 

 broader and more confluent than above, internal border greyish 

 white ; secondaries with the basal two-thirds and abdominal border 

 white ; a spot across the base of the cell and a broad irregular 

 oblique belt from near base of costa across the cell, a short central 

 costal streak and a spot just below the latter, greyish olivaceous ; 

 external third occupied by a broad belt of the same colour, slightly 

 flecked with whitish and grey at apex and towards anal angle (so 

 as vaguely to indicate the pale outer border which occurs in P. zebra); 

 fringe of all the wings white, spotted with grey. Body below 

 sordid white, the venter rather purer than the pectus. Expanse of 

 wings 24 millim.
