30 SOUTH-AFRICAX BUTTERFLIES. 



by Pieriuas of related genera. The irQitation of M. Agatliina by Pieris 

 Thysa, Hopff., is deceptively close in both sexes; and M. Poppea, 

 (Cram.), is similarly copied by P. PJiodope, (Fab.), on the West Coast. 

 M. Agathina is also mimicked by the $ Eronia Argia, (Fab.).

$ White, with black marginal spots. Fore-wing : costa narrowly, 

 apex more widely, black ; four 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 upp)er side. Fore-ioing : apex yelloiv-ochreous ; on its hind- 

 marginal edge are three small spots continuous of the row along hind- 

 margin ; lase broadly suffused loith deep orange-red. Hind-iving : 

 entirely pale ycllow-ochreous ; hind-marginal spots rounder than on 

 upper side ; portion of costa above costal nervure orange-red. 



$ Varies from didl ivhitish-ochrcoiis to didl orange-oehreous ; sp)ots 

 on hind-margins larger than in $. Under side. — As in $, but ground- 

 colour of fore-iving 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 $, 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 ^, 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 



^ Oberthtir records that specimens taken in Abyssinia by M. Raffray were smaller, and 

 with less developed black markings than those found in Natal. A 6 example captured by 

 Colonel Bowker at Quilimane presents the same differences.
