The fore-wings of this fine species are rather narrow and subfalcate, 

 with the apical margin rather waved ; they are of a huff-brown, very 

 much irrorated with darker scales, the basal half of the wing and costa 

 being much paler ; they are traversed by three very oblique brown 

 strigse, of which the middle one is the thickest ; the anterior one is 

 very much waved and dentated, the second much-waved, having at- 

 tached to it near the middle of the wing a small oval ocellus, of which 

 the anterior half is brown and the other half vitreous : the third fascia 

 arises on the costa from a larger brown spot. The hind-wings are 

 similarly coloured to the apical portion of the fore-ones, except that 

 the anterior portion is of a rich pinkish red which extends half round 

 the ocellus, which is large and central, having a small semicircular 

 vitreous pupil surrounded by a black iris round which is a very 

 slender luteous ring, and another black, followed by a pinkish-buff 

 broader ring, and this by a white one. Across the base of the wing 

 is a brown angulated striga, being the continuation of the central one 

 of the fore- wings, and from the inner margin of the ocellus runs a waved 

 one to the anal margin, followed by another running across the wing 

 parallel to the apical margin. The apical part of the wing is much 

 freckled with brown, and a thin brown line runs just within the mar- 

 gin. The thorax is dark brown, with a pale buff collar ; the hind- 

 part pale, with a short black bar. Wings beneath coloured as above, 

 except that the fore-ones are tinged on the inner margin with pink, 

 which colour is entirely wanting in the hind-wings, which are more 

 freckled with brown than above, the ocellus being replaced by a small 

 brown spot. 



The pectinations of the antennae of the only specimen I have seen 

 (which is probably a female) are comparatively short, each antenna 

 having thirty-eight rays on each side (four from each joint), and about 

 one-fourth of the antennae at the apex is destitute of rays. The palpi 

 are very small, but distinct. 



This fine insect is unique in the collection of Conrad Loddiges, 

 Esq., of Hackney, who is not aware of its locality ; but from its rela- 

 tionship to S. Isis, I have but little doubt of its being a native of 

 Africa.

I have not seen any specimen of this insect, the veins of which 

 agree rather with Saturnia than Lasiocampa, although the antennae 

 seem but narrowly pectinated.
