130 LEPIDOPTERA. 



the solution of Enigma No. 16. I took two specimens in 

 Headley Lane, June 23rd ; and the middle of July I found 

 the Lotus-mining larvae freely ; none of these have yet 

 produced moths ; yet as Frey gives September and October 

 as the time for the larvae, there ought to be an August 

 brood of the imago. 



Nepticula argentipedella, I. B., p. 303. This is the 

 solution of Enigma No. 10, I having bred two specimens 

 from the birch leaves sent me last autumn by Mr. Wilkinson. 



Nepticula Alnetella, Ent. Ann. 1856, p. 43* I found 

 the larvae of this not uncommon on Reigate Heath in 

 September, and plentiful near Beckenham in October. 



It has been suggested to me that there are two species of 

 Nepticula mining in alder leaves.
