288 CURCULIONIDES. 



[Schonherr (3, 62) has described a Liocus praepotens Say, which. 

 is evidently this 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 Gleonus trivittatus Say, 

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

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

 Leg.]

 tle curved, punctures large at base, smaller at tip; base grooved 

 above ; head punctured, small ; antennae rufous : thorax almost as

 wider before the middle and the lateral ones behind the middle :
