  lateral 
  lobes 
  with 
  no 
  lateral 
  carinae, 
  both

  metazona, 
  at 
  least 
  in

   angulate, 
  being 
  bent 
  forward 
  laterally, 
  its 
  posterior 
  sulcus 
  similarly

   distinctly 
  transverse, 
  almost

  lobes 
  

   approximate 
  in

  by 
  the 
  com- 
  

   pression 
  of 
  the 
  subgenital 
  plate, 
  the 
  lateral 
  margins 
  of 
  which 
  are 
  

   straight 
  throughout, 
  and
