and the outer side of the third of which are suffused with 

 brown towards the costa. The hind-wings are greyish-yellow 

 externally, and more or less rust-coloured towards the base, 

 with the anal angle white. 



The larva feeds singly on young oaks, and is very difficult 

 to rear. It resembles that of SnierijitJiiis ocellattis and 

 AmorpJia popiiU^ but has the lateral lines yellowish, and alter- 

 nately broad and narrow ; the last extends to the pale blue 

 horn. The head ends above in a short bifid point, and is pale 

 green bordered with orange ; the spiracles are deep yellow. 

 The metallic brown pupa is formed in the ground, and the 

 moth appears in about three weeks.

In this genus the proboscis is short, but distinct, and the 

 wings are narrower than in Laothoe^ and not denticulated. The 

 fore-wings have a large concavity in the middle, and a smaller 

 one above the hinder angle, which forms a rounded projection. 

 The hind-wings have two rounded concavities. The wings 

 are variegated, and differ considerably both in colour and in 

 the extent of the markings in different specimens.
