segments, aud with a slightly raised ridge on the posterior 

 portion of each ; pale pink, paler beneath ; head light chest- 

 nut ; dorsal plate rather broad, yellowish brown ; anal plate 

 minute, brown. 



August, on CentauTca scahiosa, in the flower or seed-head, 

 eating out the seeds and the pith at their base. Before the 

 involucrum wil;hers and spreads open, the larva is full-fed and 

 has deserted it to spin a tough cocoon under a stone or 

 among rubbish on the ground. Here it remains unchanged 

 until the following June or even July, a very short time 

 being spent in the pupa state. 



Eather a local species, but often common upon the sea 

 coast aud inland in chalky districts. Of rather deliberate 

 habits, hiding among undergrowth ; easily disturbed in the 

 daytime but keeping near its favourite Centaurca and 

 often sitting upon it. Rather a handsome and attractive 

 insect ; found in Kent, Surrey, Sussex, the Isle of Wight, 

 Dorset, Wilts, Berks, Essex, Suffolk, Norfolk, Cambs, 

 Oxfordshire, and Herefordshire ; but apparently not in the 

 midland and northern counties ; in Wales common in the 

 limestone districts of Pembrokeshire ; in Scotland in the 

 extreme south-west, about Wigtown ; and in Ireland on the 

 Dublin coast, at Sligo, and Armagh. Abroad it is found in 

 most parts of Central Europe, the North of Italy, and Livonia.
