1 18 NEW ENIGMAS FOR SOLUTION. 



on-tbe-Main and at Ratisbon. Herr Hofmann bas bred 

 specimens of this insect, but I have not been yet able to refer 

 it; to any described species. 



86. A Gelechia ? larva, found near Ratisbon by Herr 

 Hofmann, feeding in the heads of Linosyris vulgaris (^Chry- 

 socoma), and devouring the seeds and fructification of that 

 plant, wliich is nearly allied to Solidarjo virgaurea. 



87. A Gelechia larva (supposed to be that of Erlretella)^ 

 found by Mr. Wilkinson of Scarborough, at the end of Sep- 

 tember, feeding in the flowers of the heath. 



88. A Nepticula larva in birch leaves, found by Mr. 

 Healy, Mr. M'Lachlan and others, in October. The mine 

 is contorted, with a thread of black excrement; a peculiarity 

 of the mine is that when the larva is young, it does not eat 

 ihe whule thickness of the leaf, so that the first portion of 

 the mine remains green. 



89. A larva (^Parasia ?), found by Herr Hofmann, near 

 Ratisbon, in October, feeding on the seeds of Anthemis 

 Tinctoria, boring through them just as the larva of Parada 

 Lappella does in the seeds of the burdock. 



90. A Nepticula larva in the leaves of Agrimohia Eupa- 

 toria, found by Mr. Healy in October, near Croydon. The 

 mine of this eventually forms a complete blotch. This is the 

 third species which feeds in the Agrimonia, and possibly 

 there are yet others.
