SOUTH-AFRICAN BUTTERFLIES.

Thysa, HopfF., is deceptively close in both sexes; and M. Poppea, 
(Cram.), is similarly copied by P. Rhodope, (Fab.), on the West Coast. 
M. Agathina is also mimicked by the $ Eronia Argia, (Fab.).

$ White, loith Mack marginal spots. Fore-iving : costa narrowly, 
apex more widely, black ; fonr small black rounded spots on hind- 
margin at ends of nervules. Hind-wing : six black spots on hind- 
margin at extremities of nervules. Under side. — Markings similar 
to those of icpper side. Fore-wing : apex yellow-ochreous ; on its hind- 
marginal edge are three small spots continuous of the row along hind- 
margin ; hase broadly suffused with deep orange-red. Plind-ioing : 
entirely pale yellow-ochreous ; hind-marginal spots rounder than on 
upper side ; portion of costa above costal nervure orange-red. 
$ Varies from didl tvhitish-ochrcous to d%dl orange-ochreous ; spots 
on hind-margins larger than in $. Under side. — As in but ground- 
colour of fore-wing usually dull yellowish instead of white, and its apex 
and whole of hind-wing of a deeper yellow-ochreous. 
In the ^ the lowest hind-marginal spot in the fore-wing is at the 
extremity of the first median nervule, and is much smaller than the 
rest, being occasionally a mere dot ; while in the hind-wing the two 
uppermost, respectively on second subcostal and radial nervules, are 
considerably less than the other four. 
In the % the spot on first median nervule of fore-wing is propor- 
tionately larger than in the 3^, there is an additional spot (very small) 
at extremity of submedian nervure, and there is more or less tendency 
in all the spots to extend acutely in the direction of base. The spots 
of the hind-wing, although sometimes much larger than in (J, do not 
exhibit this tendency. 
In both sexes the neuration of the under side is more or less 
clouded with whitish where traversing the ochre-yellow ground-colour, 
and the costal edging of the fore-wing is much more densely white- 
scaled than on the upper side.-^ 
The % s exhibit on the upper side gradations, from being only 
^ Oberthiir records that specimens taken in Abyssinia by M. Raffray were smaller, and 
with less developed black markings than those found in Natal. A i example captui-ed by 
Colonel Bowker at Quilimane presents the same differences.
