^ Pull fuscous-yellow-ochreouSj with hlach spots^ and dull hlachish 
hordcTs. Fore-wing : a large, more or less defined, elongate spot at 
end of, and running into, cell ; beyond it, from costa, a row of con- 
fluent spots, angulated inwardly on third median nervule and extending 
to middle of submedian nervure (the whole of the row below third 
median is often wanting or very faintly marked) ; costa rather narrowly 
bordered with greyish; hind-marginal blackish border broad, nearly 
even throughout ; a smooth greyish sp}ace covers median nervides at their 
origin. Hind-udng : the broad blackish border leaves only an inner- 
marginal and discal ochreous space, not extending above discoidal 
nervule ; crossing ochreous nearly to submedian nervure an ill-defined 
macular stripe. Under side. — Hind-wing and horders of fore-iving 
hoary-grey, the former crossed hy two roius of faint-hrownish confluent 
spots. Fore-wing : ixde yellow-ochrcons ; spots as above, but smaller and 
more distinct, — that closing cell divided into two, of which the inner 
is very much the smaller ; below the inner of these two, outside cell, 
a small round spot ; hind-rnarginal border faint-fuscous towards anal 
angle, sometimes marked interiorly by a row of very indistinct, small, 
dark spots. Hind-ioing : markings variable and often very indistinct ; 
macular row before middle very irregular and sometimes very much 
broken up, — a portion of it always marks end of cell, where it is often 
confluent with the more regular, broader, and better-defined discal 
row ; two or three indistinct brownish spots near base. Cilia white 
or whitish, interrupted with dull-blackish on nervules. 
$ Similar, but ochreous much clearer and yellower, so that the black 
spots are more conspicuous ; horders hrownish. Fore-wing : spot at end 
of cell often divided, sometimes confluent with discal row on third 
median ; no grey space at origin of median nervules. Rind-wing : 
a streak closing cell sometimes visible. Under side. — As in ^, but 
markings of hind-wing sometimes better marked. 
This species varies much in both sexes, both as""regards the extent and 
clearness of the ochreous-yellow of the upper side, and the definition, size, and 
shape of the spots on the under side of the hind-wing. Near Cape Town and 
at Stellenbosch, the dusky typical form (described by Linnseus and the ? 
figured by Cramer) prevails, and in these the discal black spots are almost 
always strongly developed on the upper side. At Triangle Station (elevation
