  slightly 
  narrowed

  LEPTOCRYPTUS, 
  gen. 
  nov. 
  

  

  Resembles 
  Ceratocryptus 
  in 
  the 
  form 
  of 
  the 
  body 
  and 
  

   wings, 
  but 
  it 
  wants 
  the 
  frontal 
  tubercles 
  ; 
  the 
  apical 
  man- 
  

   dibular 
  tooth 
  is 
  longer 
  and 
  sharper 
  ; 
  the 
  prothorax 
  above 
  

   is 
  more 
  widely 
  and 
  deeply 
  depressed, 
  or 
  incised 
  in 
  the 
  

   middle 
  ; 
  the 
  metathoracic 
  spiracles 
  are 
  oval, 
  not 
  linear 
  ; 
  

   the 
  spiracles 
  on 
  the 
  petiole 
  are 
  placed 
  shortly 
  behind 
  the 
  

   middle, 
  not, 
  as 
  in 
  Ceratocryptus, 
  between 
  the 
  middle 
  and 
  

   the 
  apex 
  ; 
  and 
  the 
  ovipositor 
  originates 
  from 
  the 
  ventral
