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

 an inch. 



Like other species of the genus, A. exulans varies somewhat 

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

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

 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. filipendula.
