in cell; 6 from areole, a little above the upper angle; 7 from areole just before 
its end; areole long, reaching till about frd upper angle to apex; 8 and 9 
stalked for half the length of 9 beyond the end of the areole, stalk originating 
from end of areole; 10 almost from end of areole, but from beyond 7; 11 from 
beyond frd upper median; 12 parallel to costa; hind wing semicircular; costa 
arched at frd; apex produced from 8 to 7, then acutely rounded; termen very 
oblique, slightly lobed at 4; tornus well rounded; inner margin rounded and 
oblique ; 1 a straight ; 1 b curved ; 2 from lower median at before frd ; 3 from 
near lower angle ; 4 from lower angle ; 5 from above middle of discocellulars of 
which the lower is oblique and the upper nearly erect; 6 and 7 on a stalk of over 
frd and from upper angle; 8 parallel to upper median to near upper angle, then 
oblique to costa before apex ; a faint bar at frd of upper median. Abdomen of <$ 
with a forked tuft of hairs and lateral black spots as in Antheua and P haler a ; 
hairs of thorax short, smooth or only very slightly crested. The venation appears 
to differ in some specimens as much as in Antheua, some specimens of ornata 
have vein 7, stalk of 8, 9 and 10 from end of areole; the length of stalk 6-7 
of hind wing also varies somewhat ; in woerdeni the areole is shorter (about T U th 
of wing length), 6 is from areole at just before middle; 7 from stalk of 8, 9 at fth 
of stalk; 9 from 8 at frd distance of end areole to apex; 10 from stalk of 8, 9 
at beyond frd of stalk and far beyond origin of 7. 
Three species were placed in this genus by other writers, but I removed 
aurifodinae from here to Antheua. 
The remaining two species may be separated as follows: 
la. Abdomen orange-yellow above; thorax almost entirely yellow; fore 
wing with stigma at the end of cell and with a terminal dark 
shading ......... woerdeni 
b. Abdomen black to near tip above; thorax yellow, much suffused with 
brown; fore wing without a stigma and with a broad terminal 
dark line which is much crenulated .... ornata

I have both sexes of this species from Transvaal (Pretoria, Waterval onder, 
Kaapmuiden, Noordkaap, Barberton) ; Natal (Karkloof, New Hanover,
