joint with one short ray on each side; the rays set on obliquely and 
directed backwards, the tips of the rays being turned forwards. 
There are no traces of palpi to be perceived. The veins of the 
fore-wings are arranged as in the typical Saturnia.

The texture of this insect, as described by Boisduval, is “ mince et 
délicate”’ ; the same author states that it is “tout autant une Liparide 
qu'une Saturnide.” The veins of the fore-wings are however ar- 
ranged as in the typical Saturnie; but the antenne are different, 
consisting of about thirty-six joints, bipectinated in both sexes with 
only thirty-four rays on each side, each joint except one or two at 
the apex emitting only a pair of rays, which are rather short. The 
palpi are distinct and turned upwards, extending rather further than 
the hairs of the face: the spiral tongue is distinct. 
Boisduval states that this species ‘‘ vole en plein jour. Une année, 
aux environs de Port Natal, on aurait pu en prendre par centaines en 
quelques heures. Deux ou trois jours aprés il n’existait plus. La fe- 
melle que nous est inconnue ne vole pas, peutétre méme est-elle aptére, 
et tous les males voltigeaient sans doute a sa recherche.” The female 
is however winged and scarcely distinguishable from the male, as I 
have ascertained by extracting eggs from the abdomen of a specimen 
in the British Museum collection, which M. Boisduval would doubt- 
less have taken for a male. 
The structure of the antennz and presence of a spiral tongue, 
together with the fragile texture of the insect, will require a subgenus 
for its reception.
