152 NEW ENIGMAS FOR SOLUTION. 



79. A mining larva, collected by Herr Schmid, near 

 Frankfort, at the end of October, in the leaves of Lysima- 

 chia vulgaris ; the mine is slightly puckered, but yet reminds 

 one considerably of the mine which Stepkensia Brunnichella 

 constructs in the leaves of Clinopodium. 



80. An Elachista larva, collected by Herr Hofmann at 

 Ratisbon early in October ; it mines the leaves of Hierochloa 

 australis, making straight, rather narrow mines, buteventually 

 several side by side, so as to occupy nearly the whole width of 

 the leaf; the mine is perfectly clean, the excrement being ex- 

 cluded through a hole in the cuticle.
