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 SaturnicB.

The texture of this insect, as described by Boisduval, is " mince et 

 duhcate " ; the same author states that it is " tout autant uue Liparide 

 qu'une Saturnide." The veins of the fore-wings are however ar- 

 ranged as in the typical Saturnice ; but the antennae 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 annee, 

 aux environs de Port Natal, on aurait pu en prendre par centaines en 

 quelques heures. Deux ou trois jours apres il n'existait plus. La fe- 

 melle que nous est inconnue ne vole pas, peutetre meme est-elle aptere, 

 et tons 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 antennae and presence of a spiral tongue, 

 together with the fragile texture of the insect, will require a subgenus 

 for its reception.
