SATURNIA CYNTHIA. 141 



as well as the rest of the head, are brown. The 

 spiral tongue appears to be wanting ; the antennae 

 are slightly bipectinated, being gradually more slen- 

 der from about one-third of the distance from the 

 base to the apex. The legs are short. 



This insect seems allied to Saturnia alenda, 

 Drury, vol. ii. pi. 19, and S. phcedura, Drury, vol. ii. 

 pi. 24 and 25, both of which are from Sierra Leone, 

 but differing from both in the form of the wings. 



In the possession of palpi, S. Iris agrees with 

 Aglaia rather than Saturnia, but that is evidently a 

 character of slight importance ; the giant Atlas moth 

 of China has similarly developed palpi, and yet 

 nothing would be more absurd than to place these 

 three species in one modern genus.

The expansion of the wings is about five inches : 

 head and antennae greyish-brown, the latter strongly 

 pectinated ; thorax and abdomen lighter grey ; wings 



* This and the following species might perhaps be included 

 in Hyalophora, but as they deviate somewhat from the type of 

 that genus, the old name has, in the mean time, been permitted 

 to remain.
