and Harma (all Nymphalinai) are each represented by a single species 

 only. 



The following table exhibits, as far as known to me, the total 

 representation of the Rhopalocera in Extra-Ti'opical Southern Africa, 

 and the proportion borne to it by the genera and species which appear 

 to be peculiar to the Sub-Region : — 



South-African Rhopalocera. 



Omitting the solitary representative of the Erycinidm, it will be 

 seen that the several Families almost follow their scientific order as 

 regards their respective numbers of genera and species, the Nymphalidm 

 leading ■ with 3 5 genera and 118 species ; Lycccnidm following with 

 much fewer (15) genera, but with an almost equal number (116) of 

 species ; and the Papilionidm and Hes])erid(B succeeding, with the same 

 number of genera (9), but with 84 and 61 species respectively. 



The genera most richly represented are two of the Family Lycccnidm, 

 viz., Lycmna (46 species) and Zeritis (28 species), and one of the 

 Family Papilionidce, viz., Teracolus (37 species). The next most 

 numerous genus is the Nymphalide one of ..4cr(X'a, which has 20 South- 

 African species. 



As regards endemic forms, the genera richest in them — apart from 

 the six genera above mentioned as themselves peculiar to South Africa 

 — are exactly those which have just been indicated as the most fully 

 represented in the country, viz., Lycmna with 29, Zeritis with 23, and 

 Teracolus with 22 species, which have hitherto not been recorded as 

 occurring out of the Sub-Region. As regards genera, the LyccenidcK 

 exhibit, both absolutely and relatively, the greater peculiarity, more than
