apex of the fore-wing is not rendered conspicuous by any bright con- 

 trasting colour. All these groups except the first are specially preva- 

 lent in the barren or even desert tracts of Eastern North -Tropical 

 Africa, Southern Arabia, and Western India ; but it must at the same 

 time be noted that a good many of the brightly-tipped species of 

 other groups inhabit the same countries. 



The under side, where not white, is singularly colourless, apart 

 from various tints more or less approaching the isabelline ; and it is 

 only in the Celimene, Fulimene, and Clirysonome sections that a more 

 lively coloration, characterised by red neuration, is found. 



In South Africa, undoubtedly the tract most productive of this 

 genus is that lying between the tropical boundary and 30° lat. ; 

 indeed, the Snhfasciaius, Agoyc, lone, Uvenina, and Vesta groups do 

 not appear to range any farther to the southward, and the Celimene 

 group stops short about lat. 28° As far as my records go, all the 

 twelve South-African groups are represented in Transvaal (eighteen 

 species known) ; nine in Cape Colony, including the territories of 

 Griqualand West and Basutoland (seventeen species) ; eight in Natal 

 (eighteen species) ; eight in Swaziland (thirteen species) ; eight in 

 Delagoa Bay (twelve species) ; and six in Kaffraria Proper (eleven 

 species). The comparative richness of the Cape Colony is due to its 

 receiving several interior forms along its north-western and northern 

 border, viz., Suhfasciatus, Uvenina, Microcale, and Lais, and possessing 

 one (BowJccri) peculiar to that tract. 



Besides the last-named butterfly, only four others seem to be pecu- 

 liar to South Africa, viz., Speciosa, Wallengr. ; Johina, Butl. ; Halyaitcs, 

 Butl. ; and Topha, Wallengr. ; and it is not improbable that further 

 exploration will prove that even these few also inhabit the tropical 

 region. 



In the Cape Colony Teracohis thins out westward, only two species 

 — small varieties of Evenina, Wallengr., and Omphalc, Godt. — having 

 been taken in Little Namaqualand, and the latter form in the south- 

 west extending as far as Robertson. The Knysna district, besides 

 the variety of Omphale, has hitherto yielded only Achine, Cram., and 

 Antevip)pe, Boisd. ; but the eastern districts are far more productive, 

 possessing, in addition to the three last-named species, nine others, 

 viz., Eris, Klug ; Annce, Wallengr. ; Wallengrenii, Butl. ; Aiixo, Lucas ; 

 Topha, Wallengr. ; Gavisa, Wallengr. ; Theogone, Boisd. ; Phlegetonia, 

 Boisd. ; and Antigone, Boisd. All the species that I have seen in life 

 flit actively along the edges or about the outskirts of woods, with the 

 exception of Eris, which flies with great rapidity over more open 

 country. Even swifter than this last is (I learn from Colonel Bowker) 

 the beautiful Suhfasciatus — the type of the genus— which occurs in 

 Griqualand West.
