The treatment of the genus by Perkins is the best to be found 
in the literature.°° It seems probable that further study will show 
many of the species to be subdivisible into geographic races, or 
at least into topomorphs. 
The genus Banza shows close similarity in general appear- 
ance to the genus Belocephalus, peculiar to the extreme south- 
eastern United States. 
Ten species of the genus are recognized by us, their distribu- 
tion being as follows: 
Hawai. nitida (Brunner) 
Maui, brunnea (Perkins) and mauiensis (Perkins ) 
Lanai. deplanata (Brunner ) 
Molokai. molokaiensis (Perkins ) 
Oahu. parvula (Walker) and unica (Perkins) 
Kauai, kauaiensis (Perkins) and affinis (Perkins ) 
Banza parvula (Walker)
