 band, black. 



Length 6 millim. 



Head impunctate, the frontal tubercles flattened, testaceous ; 

 antennae extending to the middle of the elytra, black, the first

 robust ; thorax nearly three times bi'oader than long, the sides 

 straight, the anterior angles oblique, the basal sulcus shallow, the 

 perpendicular grooves at the sides deep, the surface impunctate, 

 black ; scutellum black ; elytra widened posteriorly, minutely 

 punctured, testaceous, a transverse band, its inner margin concave

Hah. Peru. 



Allied to L. batesi Baly, but with difi'erently coloured antennse

 flavous. 



Var. Elytra testaceous, the basal poition more or less black 

 only. 



Length 2 millim. 



Head impunctate, flavous; the eyes entire, frontal elevations 

 distinctly raised, clypeus flat ; antennae quite extending to the 

 apex of the elytra, very slender, entirely flavous, the second and
