Family TORTRICIDyE. 

 Eucosma crenana Hiibner. 



I have collected this European species at Kaslo, British Colum 

 bia, and bred the larvag on .willow. The specimens have been 

 shown to Mr. W. D. Kearfott and Dr. C. H. Fernald, who are 

 of the opinion that the species may be distinct from the European 

 one. I cannot, however, see the slightest reason for it 



Eucosma solandriana Linnaeus. 



I have received this European species from Victoria, British 

 Columbia, from Messrs. A. W. Hanham and E. M. Anderson. 

 Three of the forms of this strikingly variable species are repre 

 sented, the nearly unicolorous form, the dark one with white 

 dorsal patch and the light one with brown dorsal patch. In 

 Europe the larva is known to feed on willow and birch, and the 

 same will probably be found to be the case in North America.
