154 AUGUST. 



(Plantago lanceolata), and the pretty Gracilaria 

 auroguttella among Hypericum. 



Among sloe bushes we shall find Or nix torquillella, 

 while Ornix Betulce occurs among birches, and Ornix 

 Avellanella among nut bushes. 



Among bullrushes we shall find Nonayria Typhce 

 and on the trunks of elms the beautiful Cosmia diffinis 

 may be found. 



In the leaves of aspens (JPopulus tremula) the very 

 curious and interesting larva of Phyllocnistis suffusella 

 may be found feeding on the juice that lies between 

 the skin of the leaf and the parenchyma ; the mines 

 are not at first sight perceptible, but when we hold the 

 mined leaf between our eye and the light, looking 

 along its upper surface, we see a tortuous shining 

 track reflecting prismatic colours as if a snail had 

 crawled over it — this is the mine of P. suffusella.
