genus ; thus giving the natural 

 histories of forty-eight species. 



Should, however, the Subscri- 

 bers to this Work prefer a greater 

 variety than this arrangement 

 would furnish, perhaps they will 

 have the goodness to make their 

 wishes known. 



In the genera Bucculatrix and 

 Depressaria much material has 

 already been collected ; and the 

 day is not distant, when another 

 volume on the genus Nepticula 

 will be called for. 



Having received a vast amount 

 of assistance in the present volume 

 from Professor Frey of Ziirich, 

 his name has been added on the 

 title-page as one of the assistant- 

 authors. 



Mais peut-etreles Souscripteurs 

 a cet ouvrage aimeraient plus de 

 variete, qu'ils n'obtiendront par 

 cet arrangement, et en ce cas il 

 serait a desirer qu'ils eussent la 

 bonte d'exprimer leur volonte. 



Dans les genres Bucculatrix 

 et Depressaria nous avons deja 

 ramasse beaucoup de matiere, et 

 le jour ne tardera pas d'arriver 

 lorsqu'on aura besoin d'un autre 

 volume sur le genre Nepticula. 



Le Professeur Frey de Zurich 

 ayant considerablement aide au 

 progres de ce volume, son nom se 

 trouve ajoute a ceux des collabo- 

 rateurs.
