  somewhat 
  triangular 
  at 
  the 
  base, 
  curved, 
  narrowed 
  

   towards 
  the 
  apex, 
  and 
  bluntly 
  toothed 
  there. 
  Palpi 
  

   longish. 
  Antennae 
  long 
  and 
  slender. 
  The 
  fore 
  lobe 
  of 
  

   the 
  mesonotum 
  is 
  largely 
  raised 
  and 
  does 
  not 
  reach 
  to 
  

   the 
  middle 
  of 
  the 
  mesonotum, 
  which 
  is 
  depressed 
  behind 
  

   it. 
  Scutellum 
  large, 
  only 
  slightly 
  roundly 
  raised. 
  The 
  

   median 
  segment 
  is 
  elongate, 
  has 
  a 
  gradually 
  rounded 
  

   slope 
  to 
  the 
  apex 
  and 
  has 
  no 
  keels 
  ; 
  its 
  spiracles 
  are 
  

   oval 
  and 
  are 
  placed 
  beyond 
  the 
  middle, 
  half-way 
  between 
  

   it 
  and 
  the 
  apex 
  in 
  a 
  hollow. 
  Abdomen 
  long 
  and 
  slender 
  ; 
  

   the 
  petiole 
  long 
  and 
  slender, 
  not 
  curved 
  at 
  the 
  apex, 
  longer 
  

   than 
  the 
  second 
  segment 
  ; 
  its 
  spiracles 
  small, 
  round, 
  and 
  

   placed 
  shortly 
  beyond 
  the 
  middle 
  ; 
  the 
  gastrocceli 
  are 
  

   small, 
  indistinct. 
  Legs 
  long 
  and 
  slender 
  ; 
  the 
  hinder 
  

   coxae 
  large 
  ; 
  the 
  tarsi 
  spinose 
  ; 
  their 
  claws 
  long, 
  curved 
  

   and 
  thickened 
  at 
  the 
  base 
  ; 
  the 
  front 
  tarsi 
  are 
  bent 
  at 
  the 
  

   base 
  ; 
  the 
  fore 
  calcaria 
  curved, 
  pilose. 
  

  

  Unfortunately 
  I 
  have 
  only 
  a 
  6 
  of 
  this 
  genus. 
  In 
  the 
  

   form 
  of 
  the 
  abdomen 
  it 
  does 
  not 
  differ 
  much 
  from 
  

   Mesoleptus, 
  but 
  in 
  other 
  respects 
  it 
  differs 
  completely 
  from 
  

   that 
  and 
  from 
  any 
  known 
  genus 
  of 
  the 
  Tryphonides. 
  It 
  is 
  

   undoubtedly 
  nearly 
  related 
  to 
  Baliena, 
  as 
  is 
  shown 
  by 
  their 
  

   agreement 
  in 
  the 
  form 
  of 
  the 
  head, 
  thorax, 
  and 
  legs, 
  but 
  

   differs 
  in 
  the 
  fore 
  wings 
  wanting 
  the 
  areolet.
