could never have tasted or felt the perfume of this American plant, nor could even its 

 progenitors have done so, selects it, the only one of its species in my grounds or in the 

 country, for its food, destroys it completely, and touches no other! How can you ac- 

 count for this? Could the (E. speciosa have had a perfume (to me the flower has but 

 a slight scent) so strong to the senses of this insect as to attract it in the mass? Please 

 to ask any entomological friends if that is the way they can account for this proceed- 

 ing, or can it be accounted for in any other manner ? " 



Mr. Douglas remarked that probably the usual food of this Galeruca was some 

 plant of the same natural order as (Enothera, but that this does not always apply, for 

 he once, in this country, found caterpillars of Cucullia Verbasci feeding on Buddlea 

 globosa, a native of Chili, and not in the same natural order as Verbascum, on the 

 leaves of which they usually feed.* 



Mr. Douglas read descriptions of ten species of Gelechia, being the completion 

 of his Memoir on the British species of that genus. On a future occasion he intended 

 to offer some observations on the structural characters of the genus, and now, at the 

 request of many friends, he gave the following provisional arrangement of the species, 

 according to the characters indicated by Zeller, in the * Isis,' 1839.
