This genus differs from Macrophylla merely in the number of the 
antennal joints forming the club, these being three instead of five, 
the club is in some species even longer and more curved than in 
Macrophylla, and the seventh joint is occasionally also laminate 
and long; the shape of the clypeus varies also in the species, some 
haying an inner spur on the anterior tibie, others none; the facies 
also is not uniform, being sub-cylindrical in some and _ plainly 
depressed in others; these differences, however, and also some 
other minor ones cannot be regarded as generic.
