2o6 LEPIDOPTERA. 



C. scopoliana, from Centmirca nigra, but the larva was over- 

 looked and may have fed in a root — where also it is said to 

 assume the pupa state. 



The moth sits in the daytime in plants of Ccntaurea 

 nigra, and when disturbed by the foot or the beating-stick, 

 dashes swiftly away, rising at the same time a few feet into 

 the air, but soon falls and hides again among herbage. 

 Often also it will sit upon a bit of limestone on the ground 

 — especially in its favourite haunt, a quarry — and here it 

 cannot be discriminated with any certainty until it flies up. 

 A very local species ; to be found in the chalk districts of 

 Kent, Sussex, Surrey, Essex, and Dorset, and on the lime- 

 stone of Pembrokeshire in Wales. I know of no other 

 haunts in the British Isles. Abroad it is to be found through 

 Central and Southern Europe, Norway, Finland, Livonia, 

 Armenia, and the Taurus mountain district.
