288 " CURCULIONIDES. 



[Sdionlicrr (3, 62) has described a Lixus praqwfejis Say, whicli 

 is evidently tliis species, he afterwards mentions Say's description 

 (4, 988) as being of an unknown genus : the insect is unknown 

 to me, unless it should be identical with Cleonus trivittatus Say, 

 Cure. 10, (ante 270) ; the size given is different, but this is 

 hardly sufficient to warrant us in continuing them as distinct. —
