48 IN MEMORIAM. 



Weekly Intelligencer for 1858 (vol. iv.), p. 175; it is 

 therefore by error that it appears in Staudinger and Wocke's 

 Catalogue of European Lepidoptcra as Freyella, Stainton. 

 I have named this species after my worthy friend, Heinrich 

 Frey, Professor at Zurich. (1857.) 



Nepticula iENEOFASCiATA, Frey, Heyden (E. Z. 1861, 

 p. 39). I found the larva in the middle of October in the 

 woods beyond Offenbach, mining in the leaves of Agrimonia 

 Eupatoria, along with Nepticula Agrimonice^ Frey. But 

 it does not change like that species within the leaf, but quits 

 the mine, and spins a rather flat, oval, reddish-brown 

 cocoon. The mine forms an irregular, large yellowish 

 blotch. The moth makes its appearance the beginning of 

 May. (1859.) 



Nepticula argentipedella, Zeller, Heyden (E. Z. 

 1861, p. 41). The larva mines the leaves of the birch in 

 October and the beginning of November, forming a more or 

 less rounded black-brown blotch, with paler edges. The 

 central portion, filled up with the excrement of the larva, 

 serves for its abode, and the pale margins are the places 

 where it feeds on the parenchyma. Sometimes we find a 

 number of these blotch-mines in one leaf. 



The larva quits its mine when full fed, and spins its cocoon 

 in some convenient spot ; sometimes we find many cocoons 

 close together. The cocoon is oval, slightly arched, scal- 

 loped, pale brown. 



The imago appears at the end of May, and I have not 

 observed a second brood. I have often found the mines in 

 countless numbers. I have met with it around Frankfortj 

 at Wiesbaden, in the Taunus mountains, kc. (1857.)
