Although this is the smallest British species of true Argyn- 

 nis, only measuring two inches or less across the wings, it is, 

 perhaps, the handsomest of all. 



The wings are fulvous on the upper surface, with two rows of 

 sub-marginal black spots, and the base is rather broadly black, 

 with some additional black spots between this and the band. 

 On the under surface the fore-wings are yellowish-fulvous, with 

 a few oval silvery spots at the tip ; the hind-wings have a row of 

 very large oval silvery spots extending completely round them, 

 and a large oval silvery spot in the centre. Between the cen- 

 tral spot and the marginal spots there is a red band containing 

 a row of silvery dots. The rest of the wing is of a yellowish- 

 fulvous, but the large silvery spots cover the greater part of its 

 surface. 



This Fritillary is double-brooded, being found in early sum-
