EXCLUDED SPECIES 
In so far as we have been able to ascertain, the follow- 
ing citations include all of the concepts originally pro- 
posed for the genus Ponera, or wrongly attributed to 
that genus, which have subsequently been transferred to 
other genera. It has been impossible to study critically 
all of the species cited. However, it is very probable that 
when the North and South American species of Scaphy- 
glottis are considered as a whole and are thoroughly in- 
vestigated, a number of the present concepts will prove 
to be untenable.
