18. — Lampides Boetica. (Pea Pod Argus.) Is easily 

 separated from the other blues by the hinder wings having a 

 long, slender, and somewhat twisted tail near the inner angle. 



It is of very rare occurrence in England, three specimens 

 only being recorded in Newman's work. The late Miss Eenouf 

 captured eight specimens in her garden in Burnt Lane in the 

 autumn of 1859, and she again took one in the same locality at 

 the end of August, 1872. 



19. — Lycaena JEgon. (Silver Studded Blue.) The colour
