Hind-wi7ig and apex of fore-iving 7nore or less yellowish, hut without, 
or almost ivithout, any irr oration. Fore-iving : costal bar beyond middle 
obsolete ; a faint yellowish suffusion in basal area ; discal blackisli 
spot well-marked. Hind-wing : markings as indistinct as in ^ ; orange 
edging on costa from base more developed, extending almost to end of 
costal nervure. 
Wallengren's note (loc. cit.) of posticis maris utrin(iue albis'^ ren- 
ders it clear that lie bad not before him in association with the $ 
Pigea, Boisd., the actual $ of that species (in which the under side of 
the hind-wings is pale dull-yellowish), but the $ Simana, Hopff.,^ to 
which alone among the males of the South-African species of this 
group the character in question belongs. 
The larger size of both sexes, the white under-side of the $, and 
almost spotless and unirrorated nature of that surface in both ^ and 
^, and the greater development of the blackish markings on the upper 
side of the ^, are the principal features distinguishing Simana from 
Charina. The singular character which Hopffer gives of the presence 
in the $ of the discal blackish spot between third and second median 
nervules on the under side of the fore-wing is entirely wanting in the 
seven Natalian $ s before me. I feel doubtful whether this form should 
be considered as more than a variety of Charina, Boisd. ; hitherto I 
have seen no examples linking it to the specimens of Charina which 
are little irrorated on the under side. 
D'Urban, in Natal, is the only locality known to me for this butterfly 
within South- African limits. The first $ example I saw was one taken by 
Mr. W. Morant in November 1869 ; before then I had referred two (^s which 
I captured in February 1867 to Charina. Several (^sand a 9 were received 
at the South-African Museum in 1870 from the late Mr. M. J. M'Ken; and 
in November 1881 Colonel Bowker sent me a pair taken m copula. The 
of this pair has only the very faintest traces of a few spots on the under side 
of the hind-wing, and the $ is slightly yellowish-tinged on the upper side, but 
distinctly pale-yellowish on the under side. 2

2 Altogether similar paired sexes, captured on loth December 1887 at D'Urban, have 
been kindly forwarded to me by Mr. A. D. Millar. Colonel Bowker has also sent a 
further pair, with the 9 rather whiter beneath, taken together at Malvern, near D'Urban, in 
May 1888,
