Genus HYPOCRYPHALUS, new genus. 
Antennal funicle 5-jointed, joint 5 much broader; club compressed, 
broadly oval, slightly narrowed toward base, sides equally rounded 
and faintly sinuate, anterior face with three nearly straight sutures, 
posterior face with three broadly procurved sutures, without septa; 
pronotum with basal margin extending around basal angle but not

head smaller than in the female. Type of genus, Hypocryphalus 
rotundus, new species. ;
