Beetles, infested peas may sometimes be seen in shops. The 

 habits of the Bean Beetles and of the Lentil Beetle are 

 essentially the same as those of the Pea Beetle, except that 



the adults select, and the grubs 

 feed upon different legumes. 

 Bean Beetles (Bruchus ritfima- 

 nus, Fig. 74, and B. obtectus], 

 originally members of the North 

 and Central American faunas, are 

 brought to Scotland every year

 viled " beans exposed for sale

 towns of Britain Bruchus lentis, having been identified by 

 Messrs J. Edwards and E. C. Champion from Egyptian 

 seeds at Gravesend and Birchwood, and the Chinese 

 Lentil Beetle (Bruchus chinensis] in imported lentils at 

 Dartford and Darenth Wood in Kent, Putney in Surrey, 

 and New Forest in Hampshire.
