SOUTH-AFEICAN BUTTEEFLIES. 
Fore-wing : immediately beyond terminal disco-cellular spot a whitish 
spot, and outwardly edging discal row of blackish spots a series of six 
or seven more or less developed didl-whitish spots ; blackish spot in cell 
and another below its outside cell larger than in Frotumnus, but 
suffused. Hind-ioing : almost spotless, the paler and darker markings 
of the disc being extremely indistinct ; in some specimens a broad 
deeper-fuscous shade over costal area from base to beyond middle. 
Under side. — Ahnost uniform whitish-grey, with a very faint yellowish 
tinge over disc of fore-wing ; all the markings of hind-wing very thin 
and faint ; a common sid)marginal row of very small hlackish spots, not 
sagittate. Fore-wing : all the blackish spots distinct, but separate and 
very small, except the spot below discoidal cell, which is enlarged, 
and confluent with a fuscous mark extending to base ; a small ad- 
ditional spot in discoidal cell near base. Hind-ioing : spots arranged 
as in Frotumnus, but separate, very much smaller, and extremely 
indistinct ; the discal row sharply interrupted on second subcostal 
nervule. Cilia greyish or greyish-white, very indistinctly varied with 
fuscous on nervules. 
$ Darker, without yelloiv-ochreous tinge ; all the hlack and whitish 
markings mitch erdarged. Fore-wing : black spots strongly marked and 
more or less confluent, as in typical Frotumnus ; the white spots very 
conspicuous, and those of discal row occasionally confluent ; usually 
a whitish spot between the terminal and interior disco-cellular black 
spots. Hhid-iving : disco-cellular terminal spot and discal row of spots 
better marked than in J, sometimes quite distinct, and relieved by 
whitish suffused markings corresponding to the much more conspicuous 
white ones of fore-wing. Under side. — Hind-vjing and horder of fore- 
wing pale o.shy-grey ; disc of fore-vnng much whiter. Fore-wing : spots 
larger than in but still separate. Hind-wing : all the spots larger 
and much more distinct, being of a light-brownish tint (but smaller 
than in Frotumnus). Cilia greyish mixed, but not regularly interrupted 
with fuscous. 
The characters italicised afford ready distinctions between this 
species and its congeners. In its dingy colouring the ^ is nearer to 
the $ Brachycera ; but the though nearer to the $ Frotumnus in the 
size and confluence of the black markings of the fore-wing, differs 
strikingly from both that species and the $ Brachycera in the conspi- 
cuous white spots of the same wing. The paleness and faint small 
spotting of the under side distinguish both sexes of Basuta from the 
other species ; and the greater development of the thorax (which in 
the ^ is most remarkable, and gives that sex the look of a Hesperide) 
is also a singular distinction. 
I have not met with this interesting species in life. Colonel Bowker wrote 
to me that it frequented grassy spots at Fort Bowker, near the Bashee River ; 
and Mr. W. Morant noted that he had found the species in the Orange Free 
State on stony hillsides during the month of December, and in the Transvaal
