form. We believe that, of the eleven species described, most 
are synonyms, based on features which, though often showing 
marked differences, will be found on more thorough investigation 
to be valueless from a specific or even from a racial standpoint. 
In fact it may develop that but a single plastic species exists, 
breaking into many more or less intergrading phases. 
Several aberrant specimens in the present series, discussed 
below, would each be described as- representing a new species, 
were the condition as indicated above not understood. 
The problem can be adequately worked out only by a student 
resident in the Hawaiian islands. To one interested in Orthoptera 
this should prove a most attractive, though difficult, task.
