It feeds on the common primrose, f Primula v oris, J and 

 the broad-leaved primrose, f Primula elatior.J 



This species varies in the expanse of its wings from a little 

 under to a little over an inch and a quarter. On the upper 

 side the fore wings are dark fulvous, crossed with three waved 

 and indented bars of dark blackish brown, the inner one being 

 the most ii'regular, the indentations of each meeting the next 

 one, forming a kind of mosaic work; the base is entirely of 

 the dark blackish brown colour; the extreme margin is yellowish, 

 intersected at intervals by the outside bar, which is close to 

 it, and immediately inside which is a row of dots in the fulvous 

 part, which is a row of crescents formed by the extensions of 

 the next dark bar. The hind wings are nearly entirely of 

 the dark colour, the edge being a row of widely interrupted 

 whitish yellow marks, inside which is a row of fulvous crescents, 

 each with a black triangular-shaped dot within it, and in the 

 centre of the wing three fulvous dots semicircularly disposed, 

 between which and the base is one other, which may indeed 

 be considered as the upper part of the curve, in the shape of 

 a sickle. 



Underneath, the fore wings are of a paler fulvous ground 

 colour, the outside edge being cream-colour, indented with 

 broAvu, the centre of the wing being paler than the rest, with 

 two irregular short interrupted rows of large dark brown marks 

 on it and towards the inner edge and the lower corner, and 

 towards the tip a row of light dots partly following the margin, 

 with one extra one between the row and the tip itself. The 

 hind wings are of a rather darker and richer fulvous, crossed 

 with two irregular waved bars formed of large silvery cream 

 white spots, one near the base and the other about the middle; 

 the latter has some dark markings on its inner edges, and a 

 few more between it aiid the outside, on the fulvous ground 

 colour. 



In the female there is a greater extension of the pale colour 

 on the upper surface of the fore wings, and the blackish brown 

 colour is darker. 



The eggs are found solitary or in pairs, on the under side
