J Orange-red, with blackish horders. Fore-wing: border rather 
narrow at base (where it is suffused with greyish-yellow-ochreous, 
which sometimes narrowly edges costa to a,pex), but widening greatly 
to apex, whence, abruptly narrowing on third median nervule, it is 
moderately broad along hind-margin to posterior angle, where it 
usually widens again ; base blackish mixed with ochreous. Hind- 
wing : border sometimes nearly obsolete on costa, but in many Cape 
Town examples rather broad ; always developed very broadly about 
apex, narrowed abruptly on third median nervule, and thence only a 
dentate edging to anal angle. Under side. — Hind-iuing and border 
of fore-wing greyish or broivnish ochrco2is, or often pwylish-lake, the 
former with irregular whitish streaks and spots. Fore-wing: orange 
usually paler, especially towards inner margin, which is bordered with 
whitish ; two black spots in cell, one closing it ; an inwardlj^-oblique, 
transverse, bi-angulated row of five or six beyond it, and a suffused 
submarginal row, — all spots above median nervure and its first branch 
silvery- white centred, those of cell very conspicuously ; below cell two 
blackish markings (one basal, one just beyond), usually confluent. 
Hind-iving : two small spots at base, one on costa, one in cell ; a 
transverse row of four before middle (one in cell) ; a long streak closing 
cell, usually confluent inferiorly with a most irregular, very sharply 
dentated, more or less suffused transverse stripe immediately succeeding 
it ; a small spot touching costal nervure about middle ; a submarginal 
dentated streak, often indistinct, always so towards costa. In both 
wings a rather indistinct hind-marginal row of spots, sometimes in- 
teriorly bordered by some whitish marks. Cilia blackish, interrupted 
with white between nervules. 
$ Orange usually rather pcder aiid didler, border not so dark ; 
ochreous basal suffusion usually much broader. Fore-wing : at outer 
and upper edge of orange there is often an upward projection of that 
colour as far as first radial nervule ; border often very broad at 
posterior angle. Hind-wing : apical border usually broader than in 
$ ; usually a suffused blackish spot between first median nervule and 
submedian nervure near anal angle. Under side. — As in 
This species is very variable, chiefly in the colour of under side 
of hind-wing and the distinctness of its markings, but also in the 
extent and tint of the orange of upper side, which in some specimens 
is very limited in extent, in others very broad. I have no doubt of 
this being the true Thyra of Linne, having taken one specimen near 
Cape Town which answers in every particular to the details given in 
" Museum Ludovica?, &c." In the majority of examples the under- 
side markings are not so bright as Linne notes them.
