  Antennas 
  short 
  and 
  stout,

  small, 
  

   suboblong,

  thorax,

  A 
  peculiar 
  species, 
  probably 
  entitled 
  to 
  generic 
  distinction, 
  

   the 
  neck 
  being 
  more 
  slender 
  than 
  usual, 
  the 
  pseudo-terminal 
  

   joint 
  of 
  the 
  palpi 
  remarkably 
  thick 
  ; 
  the 
  hind 
  tibias 
  but 
  little 
  

   incrassate 
  and 
  with 
  their 
  oblique 
  truncation 
  diminished 
  ; 
  the 
  

   tarsi 
  more 
  slender 
  than 
  usual. 
  At 
  present 
  to 
  be 
  placed 
  near 
  

   L, 
  punctatum.
