and thick, with a rounded end. It expands a Httle more than 

 an inch. 



Like other species of the genus, A. exu/ans varies somewhat 

 in colour and in the density or otherwise of its scahng, and 

 some of the Scotch specimens have been called A. siibochra- 

 cea^ but this form does not appear to have been separated on 

 any constant characters. 



The larva is black, with a greenish-black head, and a row of 

 yellow oval spots on each side. The incisions are yellowish. 

 It feeds on Azalea procumbens.

 This is the commonest of the five-spotted Burnets, and is 

 very variable, the spots sometimes coalescing to such a degree 

 that the insect resembles A. purpuralis, but the wings are 

 much more densely scaled. A. trifolii is found in damp woods 

 and meadows, and is a local insect in Britain, though in many 

 places on the Continent it is far more abundant and generally 

 distributed than A. filipendulce.
