This species extends practically throughout the S.-African sub- 

 region except in the neighbourhood of Natal and Zululand. On 

 the western side it is not recorded further north than Datnara- 

 land,but on the east it extends to SomaHland. T. sipylus ( = callidia) 

 is the extreme development of the wet form, and T. deidamioides 

 represents the dry-season brood. The type of T. inornata is a very 

 lightly-marked dry-season male. T. casta probably represents the 

 dry-season form in the moister parts of Central Africa, having a 

 dry-seasou upperside combined with a white underside, the ends of 

 nervules being occasionally blackened in the latter part. 2\ evenina 

 varies extremely in size in accordance with the dryness or humidity 

 of the localities it frequents, some males from Namaqualand in 

 Mr. Trimen's collection being hardly larger thau typical T. evagore 

 (Klug). 



65. Teracolus cinctus. 



Teracolus cinctus, Butler, Ann. Mag. N. H. (5) xii. p. 105 

 (1883). 



The two males in the British Museum from Victoria Nyanza 

 present much affinity to T. pallene (Hopff.), but with my present 

 available material I must regard them as distinct \ T. cinctus forms 

 an interesting link between the T. achine and evagore groups. 



66. Teracolus teeburii. 



Teracolus yerburii, Swinhoe, Proc. Zool. Soc. p. 441, pi. xxxix. 

 fig. 12 (1884). 



Teracolus stvinJioei, Butler, ibid. p. 491 (1884). 



A purely Arabian species, being the representative there of the 

 African T. daira. T. swinhoei is founded on a single female from 

 Arabia, which is clearly only a yellow variety of T. yerburii. 



1 " Among Mr. Millar's Teracoli I found two males of T. pallene (HopfF.), 

 which he had caught in Natal. In my paper I kept T. cinctus, Butl., distinct 

 from that species ; but I now think I was wrong in doing so, and that it should 

 fall as a synonym of T. pallene." [See No. 70, infra\—G:. A. K. Marshall, in
