 ing Southern Africa. By Roland Tkimen,

 Museum, Cape Town. 



[Read December 3rd, 1879.] 



Of the eleven species described in this paper three 

 {^Amauris dominicanus, Lihythea Laius, Myrina ,ficeduhi) 

 are Southern representatives of tropical West African 

 forms; two {Debis Indosa and Eurema SchcB7ieia) are 

 near allies of other South African species ; and three 

 {Precis Tuyela, Neptis Goochii and Pieris Hcemus) 

 present characters linking them to both Southern and 

 Western forms. The most interesting species is Lach- 

 noptera Ayresii, which is very distinct from L. lole — 

 hitherto the only known representative of the genus. 

 Junonia Boopis is so evidently a form of the widely- 

 ranging and variable J. Orithyia of Southern Asia, that 

 it is not without hesitation that I award it species-rank ; 

 but, as it is sufficiently different to be readily dis- 

 tinguished from the Asiatic butterfly, and as the case is 

 analogous to that of J. Cebrene and J. ^none, it seems 

 desirable that the Afi'ican insect should bear a name of 

 its own.
