  Ratio

  total 
  length 
  to 
  length 
  of 
  pronotum 
  approximating 
  that 
  of 
  

   t. 
  caliperus, 
  new 
  variety. 
  Posterior 
  process 
  more 
  acute 
  and 
  more 
  

   declivent, 
  similar 
  to 
  t. 
  trilineatus 
  (Funkhouser), 
  but

  truncate 
  styles 
  of 
  the 
  male. 
  

  

  Styles 
  broad, 
  flat, 
  suddenly 
  convergent 
  apically; 
  apices

  margins 
  produced 
  subapically. 
  

   Last

  long 
  as 
  three 
  preceding 
  sclerites 
  

   combined; 
  notch 
  in 
  center 
  of 
  posterior 
  margin 
  extending 
  almost 
  to 
  

   base;

  of 
  notch 
  acute, 
  V-shaped; 
  apical 
  portion 
  of

  of 
  t.

  (Funkhouser) 
  with 
  an

  Differing 
  from 
  the 
  typical

  * 
  Since 
  completion 
  of 
  this 
  work, 
  I 
  have 
  examined 
  the 
  type 
  of 
  lateralis 
  from 
  Horseshoe 
  Lake, 
  111., 
  and 
  find 
  

   it 
  to 
  be 
  a 
  different 
  species 
  from 
  the 
  paratype 
  in 
  the 
  U. 
  S. 
  National 
  Museum.
