Mr. Westwood exhibited portions of the leaves and stems 

 of the common Hollyhock, which had been perforated by the 

 larvae of two small beetles, Apion radiolus and Altica fuscipes ; 

 he observed that the former of these burrowed into the 

 younger and more tender parts of the stem, thus causing very 

 considerable injury to the embryo leaves and flowers. The fact 

 that the Hollyhock was an exotic plant, and was thus evidently 

 attacked by British insects, was one of much interest, as prov- 

 ing that insects will accommodate themselves to other food than 

 that on, which they appear originally to have fed : but when it 

 was recollected that the exotic Hollyhock and the indigenous 

 Malva sylmstris, the common Mallow, on which A. radiolus was 

 usually found, belonged to the same natural order of plants, 

 this would appear but a slight deviation from its usual economy. 



A paper was presented by Mr. Sells, detailing a variety of 

 daily observations made on Athalia centifolim., the black of the 

 Turnip. No facts in its history, or means for its destruction, 

 besides those repeatedly before the public, were adduced or 

 proposed. 



Mr. Westwood detailed the remarks made at the late scien- 

 tific meeting at Liverpool, by Messrs. MacLeay, &c. on the
