Tribe VIL CLYTIXL 



Our members of this tribe have the elytra banded with yellow or 

 white and black pubescence: eyes finely granulated and deeply 

 emarginate. the lower lobe always large: antennae usually shorter 

 than body in both sexes, joints rarely spined; front eoxal cavities 

 rounded, open behind, not anguiated on the sides: legs long, usually 

 slender, femora sometimes clubbed, tibiae not earinated. hind tarsi 

 with first joint very elongate. Representatives of 9 of the 14
