A NEW BRITISH BEETLE 



(Chaetocnema conducta). 



E. CHAS. HORRELL. 



In May last I gathered by general sweeping of the herbage in 

 Forge Valley, near Scarborough, two individuals of a yellow- 

 backed flea-beetle, which on examination proved to be quite 

 distinct from any British species, and on reference to Redten- 

 bacher's ' Fauna Austriaca,' it was found to agree exactly 

 with the description of the above species. Further reference

to Fauconnet's ' Faune Analytique fes Coleopteres de France ' 

 and to the ' Naturgeschichte der Insecten Deutschlands,' 

 Vol. VI., Chrysomelidae, by Weise, where there is a detailed 

 account, confirmed me in this determination, and on sub- 

 mitting a specimen to Mr. Bayford and to Canon Fowler, they 

 both agreed with my opinion. 



The species at the first glance is seen to agree with the 

 genera Chaetocnema and Plectroscelis of Fowler's ' British 

 Coleoptera' in the emargination on the inner side of the inter- 

 mediate and posterior tibiae, each edge of the emargination 

 being raised into a tooth, and agrees with the former genus in
