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 Celimcne, JSidimene, and Chrysonome 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 S^obfasciatus, Agoye, lone, Uvenina, and Vesta groups do 
not appear to range any farther to the southward, and the Cclimene 
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., Siibfasciatus, Evenina, Microcale^ and Lais, and possessing 
one (Bowkeri) 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. ; Halyattcs, 
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 Teracolus thins out westward, only two species 
— small varieties of Evenina, Wallengr., and Omphale, Godt. — having 
been taken in Little Namaqualand, and the latter form in the south- 
west extending as far as Kobertson. The Knysna district, besides 
the variety of Omphale, has hitherto yielded only Achine, Cram., and 
Antevippe, Boisd. ; but the eastern districts are far more jDroductive, 
possessing, in addition to the three last-named species, nine others, 
viz., Eris, King ; AnncG, Wallengr. ; Wallengrenii, Butl. ; Auxo, Lucas ; 
Topha, Wallengr. ; Gavisa, Wallengr. ; Theogone, Boisd. ; Phlegctonia^ 
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 Sulfasciatus — the type of the genus — which occurs in 
Griqualand West.
