but it has been several times confounded with small 

 specimens of Adippe and with Euphrosyne, and its 

 capture has thereupon been erroneously published; but 

 this must have been the effect of a description imper- 

 fectly written or read. It will be observed that the 

 form of the front wings differs in this from the rest of 

 the Fritillaries, the outer margin being concave in its 

 outline. The inner corner of the hind wings also is 

 more sharply angular. 



Above, the colouring of the wings is similar to that 

 of the others of the genus, tawny-brown and black.

 the tip, the ground colour of the hind wing is yellowish,

 and parallel with its edge, are seven dark-brown spots 

 with silver centres. 



The caterpillar is brown, striped with white, and 

 yellowish tint; head, legs, and thorns, tawny coloured. 

 It feeds on the wild heartsease, also on sainfoin and

 British butterflies, it has been found in a great many
