24 TEBACOLUS. 



in South Africa from Grahamstown to Natal, beyond which point it is probably replaced 

 by T. opalescejts. It is one of the smallest of the T. errs group, being (in its largest 

 examples) only slightly superior in size to the typical form, from which it differs in 

 its more elongated primaries, the more elongate form of the white area on these 

 wings and the apical ochraceous streaks or internervular spots, the less heavily 

 bordered inner marginal black border on the primaries of the female, and the more 

 abruptly terminated black costal band on the secondaries, which emits an acute 

 streak to the apex along the costa, instead of being extended transversely almost to 

 the radial vein." Mr. Cecil Barker procured the species on the Umfolozi River, 

 Zululand, where he makes the remark that it frequents the "thorn bush country." 

 Dr. Trimen writes : " I know of no part of South Africa where this widely-ranging 

 African species is at all numerous. I saw a few examples in the ' Thorn ' country 

 near Greytown, in Natal ; they were males, and flew with great rapidity. This was 

 in ^larch lb67, and the only other opportunity I had of seeing the butterfly in life 

 was in January and February 1870, in the Albany district of the Cape Colony, where 

 I captured one of each sex." 



" Mr. W. Morant sent me some specimens from near Pochefstroom, with the note 

 that they were taken on the 25th of February about a stony kopje, and flew very 

 strongly. Mr. D' Urban found the species near King William's Town in March and 

 April."
