LYCiENA B^TICA. 



A commonly found blue butterfly, measuring from one 

 to one and a half inches across the "wings. It is rarely 

 met with in England. The insect has a slender tail at the 

 lower angle of each hind- wing, surmounted by tw;o black 

 dots. The margins of both wings have a slight black 

 or dark brown band. The under-sides of both wings 

 are of a grey-brown colour streaked and slightly spotted 

 all over with faint white lines. On the lower angle of 

 each hind-wing the two black spots on the upper side 

 are replaced by two black ones dusted with silver, and 

 surrounded by a bright orange ring which is broader 

 at the top than at the bottom. 



The antennse are brown, slightly sprinkled with 

 white. It is found on the rough fields (especially where 

 the Lupine grows), barrancos, and hedge-rows, between 

 March and August. Specimens netted early in the year 

 are not so large as those found during May, and in the 

 summer months.
