 longer than broad; anterior trochanters of male produced at apex into 

 an elongate scale Ceramioides Saussure. 



14. Middle tibiae with a single apical spur; antennae of the sexes dissimilar, 



those of the male rolled at apex, the last segment much longer than 

 broad; mandibles of male without a large basal tooth; clypeus of the 



male longer than broad; anterior trochanters of male unarmed
