  Although 
  allied 
  to 
  the 
  preceding 
  two 
  species, 
  this 
  differs 
  in 
  

   many 
  respects 
  ; 
  the 
  angles 
  of 
  the 
  thorax 
  are 
  differently 
  

   formed, 
  and 
  there 
  is 
  no 
  tooth 
  on 
  the 
  right 
  mandible.

   this 
  latter 
  distinction 
  is 
  probably, 
  however, 
  a 
  sexual 
  one.
