Boisduval informs us that this species “ est trés commune d quatre 
a cing lieues dans l’intérieur du pays sur les Mimosa. Les cafres se 
servent du cocon qui est trés-gros et trés-solide pour se faire des 
tabatiéres. Pour cela ils y font un trou pour extraire la chrysalide, 
et ils le bouchent ensuite avec une cheville de bois.” 
A beautiful figure of this species is given by Mr. Angas in his 
plate of Zoolu Moths, fig. 18. 
This is evidently the species alluded to in the following note, pub- 
lished by M. Signoret in the Journal of the Proceedings of the 
Entomological Society of France, Annales 1845, p. xevii :—* M. V. 
Signoret présente a la Société un dessin d’une nouvelle espéce appar- 
tenant au genre Saturnia, et il communique une note a ce sujet. M. 
V. Signoret dit que le Chenille de cette espéce est inconnue, que les 
chrysalides en furent trouvées en Novembre 1844, sur un Mimosa 
prés de la rivitre Toogela, limite des frontiéres du royaume Aucayoolao, 
situé entre Lugoo-Baie et Port-Natal: l’insecte parfait a été rapporté 
par M. Campion de Douai, et notre collégue propose 4 la Société de 
lui appliquer le nom de Saturnia Campionea.”

The fore-wings are considerably rounded along the apical margin, 
and the tails of the hind-wings are much longer in proportion than 
in Mimose, Luna, &c. The veins of the fore-wings are similarly ar- 
ranged to those of S. Mimose, &c., but those of the hind-wings are 
peculiar in having the veinlet which connects the inner branch of the 
post-costal vein and the outer branch of the median vein closing the 
discoidal cell so oblique (as well as subangulated in the middle), that 
it seems like a real fourth branch of the post-costal, running down 
within the outer margin of the tail, the base of the outer branch of 
the median vein being so thin and short that it resembles the ordinary 
condition of the veinlet closing the cell, although its nearly longitudi- 
nal direction indicates its real nature as a branch of the median vein*. 
* Saturnia (Eudemonia) Semiramis, Cramer, pl. 13 A, differs materially in the 
veining of its wings from S. 4rgus. In the fore-wings the inner branch of the 
post-costal vein, instead of arising from the preceding branch in an acute fork, as 
in the typical Saturnia, arises from the middle of the transverse vein closing the 
discoidal cell, whilst in the hind-wings the inner branch of the post-costal vein 
runs within the outer edge of the tail throughout its whole length, the first 
branch of the median vein arising nearly opposite to the base of the tail, and the 
second branch at some length down the tail.
