  The 
  short 
  and 
  broader 
  head 
  of 
  the 
  female 
  of 
  hlatcMeyi 
  will 
  serve 
  to 
  

   separate 
  it 
  from 
  tenuescens. 
  The 
  new 
  species 
  is 
  described 
  as 
  follows: 
  

  

  MANOMERA 
  ORTHOSTYLUS, 
  new 
  species. 
  

  

  Male 
  (female 
  unknown). 
  — 
  Similar 
  to 
  tenuescens 
  Scudder, 
  but 
  readily 
  

   distinguished 
  from 
  that 
  species 
  by 
  the 
  cerci 
  of 
  the 
  male 
  being 
  straight 
  

   instead 
  of 
  strongly 
  incurved. 
  The 
  general 
  color 
  is 
  brown- 
  

   ish 
  but 
  is 
  probably 
  greenish 
  in 
  life. 
  A 
  lateral 
  stripe 
  runs 
  

   across 
  the 
  head 
  and

  onto

  abdomen.

  the 
  segments 
  being 
  nearly

  almost

  the

  male

  U.S.N.M.), 
  Orlando, 
  Florida, 
  

   April 
  14, 
  1907, 
  Mr. 
  Russell 
  collector. 
  

  

  A 
  paratypical 
  male 
  from 
  the 
  Scudder 
  collection, 
  from 
  Dallas, 
  Texas, 
  

   has 
  been 
  examined. 
  Except 
  for 
  being 
  a 
  little 
  smaller 
  and 
  with 
  longer 
  

   cerci, 
  as 
  long 
  as 
  apical 
  segment 
  of 
  abdomen, 
  it 
  is 
  essentially 
  like 
  the 
  

   type. 
  The 
  operculum 
  also 
  surpasses 
  the 
  eighth 
  abdominal 
  segment. 
  

   It 
  measures 
  as 
  follows 
  : 
  Total 
  length, 
  45 
  mm. 
  ; 
  pronotum, 
  2 
  mm. 
  ; 
  meso-

  The 
  left 
  middle 
  leg 
  is 
  dwarfed, 
  the 
  femora 
  measuring 
  but 
  10 
  mm. 
  in 
  length.
