742 EAST AFBICAN LEPIDOPTEItA—HOLLAXD. voL.xvin. 



Sliarpe' has given us a most instructive paper upon "The zoo-geo- 

 graphical areas of the worhl." This eminent ornithologist has recorded 

 a distinction between what he delimits and names as the "South Afri- 

 can SubEegiou" and the "East African Sub-Eegion." He, however, 

 says that "the East African Snl)-Eegion is not a very natural division, 

 and may have to be sunk in one of the others." With this view my study 

 of a number of the collections of lepidoptera made in recent years in 

 Eastern Africa leads me to concur very positively. So very lar^e a 

 proportion of the lepidoptera taken in tropical East Africa also occur 

 in the region of Natal and the Transvaal tliat it seems to me that it is 

 but natural, at least from an entomological standpoint, to sink the two 

 subregious into one, which might be designated as the Southeastern 

 African Sub-Eegion. It is characterized especially by the great develop- 

 ment of the Acraeas of the Ilorta group, and the numerous species of 

 the genus Teracolus, which are but sparingly represented elsewhere 

 upon African soil, and are altogether wanting from the hot wooded 

 valleys of the Equatorial region.
