Polyommatus argiolus. — Very local, though annually abundant in the 

 woods near Wanstead, hovering around the holly in the beginning of May.

 success.

 July. 



P. linea. — I have entered this species in the list as it may occur here, 

 though I have not observed it; it is plentiful in Darenth Wood in July.

 July.
