characters frequently appear to me to be too slight, I shall 

 feel justified in not adopting all his genera. Polydrusus and 

 Phyllobius are principally distinguished by the grooves to 

 receive the antennae, which in one are united beneath ; yet 

 there are no less than twenty-seven genera besides subgenera 

 that intervene. ' 



The following arrangement of our British species is taken 

 from the Systematic Catalogue ; but the synonyms, with two 

 or three exceptions, are copied from Gyllenhal.

 The beautiful species figured, was discovered by the Rev. 



G. T. Rudd, in a wood near Kimpton, Hants, in June, and he 

 has politely presented me with specimens. The plant Conval- 

 laria multiflora (Common Solomon's Seal), is from the same 

 locality.
