NEW BRITISH SPECIES, ETC., IN 1866. 89 



this name being, according to the latter, referable to another 

 species. 



84. Anoplus roboris, Suffrian, Stett. Ent. Zeit. (1840), 



59 ; G. R. Crotch, Proc. Ent. Soc. 19 Nov. 1866. 

 This appears to have been separated in the cabinets of Dr. 

 Power and Mr. S. Stevens, and has also been received from 

 Leicestershire by Mr. Wollaston. It was identified by M. 

 Wencker, and is considerably larger than the largest speci- 

 mens of A. plantaris.

 and Steph.,— referred by M. Brisout with doubt to this spe-

0. semirufus resembles scutellarisy but with the head, ros- 

 trum and thorax black (the latter being less rounded at tlie 

 sides), and the femora obsoletely toothed.

Also attributed to England by M. Brisout, who refers to 

 Stephens under this name and the synonym o£pilosus; but 

 both the pubescens and pilosus of the latter author have been 

 shown by Mr. Walton to be nothing but O, ilicis. 



O. pubescens resembles ilicis in form, but is more allied to 

 fagi, having stronger and coarser pubescence than that insect,
