This species, which is the type of the genus, measures 

 rather less than an inch and a quarter across the wings, which 

 are brown, generally with one or two orange spots near the 

 anal angle of the hind-wings in the male, and more in the 

 female ; the hind wings have a slender filiform tail, tipped with 

 white. On the under side a white line runs across all the 

 wings, considerably beyond the middle, which is strongly W- 

 shaped towards the inner-margin of the hind-wings There is 

 also a white sub-marginal line on the hind-wings, en which 

 rests a row of orange spots, marked outside with black, and 

 towards the anal angle is a large blue spot, which is the most 

 characteristic marking in this species. 



The larva is green, with two yellow lateral lines, and a dark 

 dorsal streak, spotted with pink. It is found in June, and 

 feeds on biack-thorn, from which it derives its name, and also 

 on white-thorn. 



The Butterfly is found in June and July in bushy places. It 

 is common in many parts of Central and Southern Europe, 

 and Northern Asia, but is somewhat local. It has been 

 erroneously reputed British.
