  areae 
  at 
  the 
  base. 
  Petiole 
  long, 
  slender, 
  carinate 
  on 
  the 
  

   lower 
  side; 
  the 
  ovipositior 
  short. 
  Scutellum 
  not 
  much 
  

   raised, 
  slightly 
  longer 
  than 
  its 
  breadth, 
  the 
  apex 
  distinctly 
  

   margined, 
  rounded. 
  

  

  Comes 
  near 
  to 
  Charops, 
  with 
  which 
  it 
  agrees 
  in 
  wanting 
  

   the 
  areolet, 
  but 
  that 
  genus 
  may 
  be 
  known 
  from 
  it 
  by 
  the 
  

   eyes 
  being 
  deeply 
  emarginate, 
  the 
  scutellum 
  depressed 
  

   and 
  the 
  antennae 
  scarcely 
  half 
  the 
  length 
  of 
  the 
  body. 
  

   Apart 
  from 
  the 
  absence 
  of 
  the 
  areolet 
  it 
  comes 
  near 
  to 
  

   Campoplex, 
  which 
  may 
  be 
  known 
  from 
  it 
  by 
  the 
  much 
  

   larger 
  and 
  more 
  elongated 
  spiracles. 
  The 
  spiracles 
  are 
  

   more 
  oval 
  than 
  in 
  Limneria, 
  and 
  the 
  median 
  segment 
  has 
  

   the 
  areae 
  more 
  numerous 
  and 
  more 
  distinct.
