GENERAL OBSERVATIONS ON THE GENUS COLEOPHORA. 



Alnus glutinosa and Alnus incana. 



Fuscedintlla and Limosipennella, 



on the leaves. 

 Alnus viridis. Fuscedindla 1 on the 



leaves. 

 Quercus Robur. Anatipennella, Pal- 



liatella, Currucipennella and Lu- 



tipennella, on the leaves. 



Corylus aiellana. Fuscedintlla, 

 Fuscocuprella and Paripennella, 

 on the leaves. 



Carpinus Betulus. Fuscedinella and 

 Currucipennella, on the leaves. 



Natural Order. Conifers. 

 Pinus Larix. Laricella, on the 

 leaves. 



Natural Order. Juncace.e. 

 Juncus effusus, conglomeratus, glau- 



cus, squanosus, &c. Ccespititella, 



on the seeds. 

 Luzula p'/lusa. Mur'inipennella and 



Ca?spititiella, on the seeds. 



Natural Order. GraminejE. 



Briza media, Holcus mollis and va- 

 rious grasses. Lixella and Or- 

 natipennella, on the leaves. 



From the foregoing list of plants 

 attacked by the larvae of this genus, 

 it will be seen that the Natural 

 Orders most frequented are the Ca- 

 ryophyllacece, the Leguminosce, the 

 Composite? and the Labiatce. It will 

 also be observed, that whereas most 

 species are attached to only one or 

 two plants, some, as Anatipennella, 

 Nigricella and Siccifulia, feed on 

 several plants, both of the Amentacece 

 and Rosacece. Paripennella and Ledi

Par cette liste des plantes dont ces 

 chenilles se servent pour nourriture, 

 on voit que les families naturelles 

 qu'elles affectionnent le plus sont les 

 Caryophyllacees, les Leguminosees, 

 lesCompositees et les Labiatees. On 

 remarquera aussi que la plupart 

 des especes ne se nourrissent que 

 d'une seule ou de deux plantes, mais 

 cependant quelques-unes, comme 

 1' Anatipennella, la Nigricella et la Sic- 

 cifolia, qui se nourrissent de plusieurs
