  — 
  Amyosoma 
  chilonis, 
  new 
  species. 
  

  

  Judging 
  from 
  a 
  comparison 
  with 
  Myosoma 
  pilosipes 
  Ashmead 
  this 
  

   genus 
  differs 
  from 
  Myosoma 
  Brull6 
  chiefly 
  in 
  the 
  character 
  of 
  the 
  first 
  

   three 
  dorsal, 
  abdominal 
  segments, 
  the 
  plate 
  of 
  the 
  first 
  being 
  nearly 
  

   parallel 
  sided 
  and 
  at 
  least 
  three 
  times 
  as 
  long 
  down 
  the 
  middle 
  as 
  

   wide 
  at 
  the 
  apex, 
  the 
  plate 
  of 
  the 
  second 
  being 
  distinctly 
  narrower 
  

   at 
  base 
  than 
  long 
  down 
  the 
  middle 
  and 
  in 
  the 
  third 
  which 
  is 
  ^dthout 
  

   oblique 
  lateral 
  furrows. 
  The 
  false 
  suture 
  between 
  the 
  second 
  and 
  

   third 
  segments 
  is 
  represented 
  by 
  a 
  smooth 
  and 
  rather 
  deep 
  channel.
