The  alleged  diversity  of  sex,  the  difference  of  habitat,  and  the  nearly  cylindric  legs, 
induce  the  belief  that  this  species  is  distinct  from  the  last,  with  which,  however,  it 
offers  a  close  resemblance  both  specifically  and  sexually. 
The  character  given  above  is  founded  on  that  published  by  the  original  observer  of 
the  species'.
