Some, and perhaps all of the species belonging to this genus, 

 roll their wings round them when they fall down, so as to re- 

 semble a piece of dead stick; and in this respect they ap- 

 proach the genus CucuUia, an opinion which M. Treitschke 

 entertains no doubt, from his having placed them next to 

 each other in his valuable work. 



The following are British species: those with a * have 

 never been recorded by any English author. 



*1. X. vetusta Hiib. — exoleta Don. 6. 187. — Mr. Stone beat 

 a fine specimen of this moth, the beginning of September, out 

 of a hedge in Darent Lane ; and I purchased another in the 

 cabinet of the late Mr. E. Blunt. Mr. Donovan has repre- 

 sented this moth, and with it unfortunately the caterpillar of 

 the next.

 tiful caterpillar of this moth is found in July in gardens and 

 marshes, feeding upon the Iris, Serratula tinctoria (pi. 183),
