SATURNIA CYNTHIA. HI 
as well as the rest of tlie 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. phoedura^ 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 C'hina has similarly developed palpi, and yet 
nothing w^ould be more absurd than to place these 
three species in one modern genus.

The expansion of the wings is about five inches : 
head and antenna 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 
tliat genus, the old name has, in the mean time, been permitted 
to remain.
