   We 
  have 
  here 
  a 
  single 
  species 
  remarkable 
  by 
  the 
  small 
  scales 
  which 
  cover 
  the 
  surface. 
  

   The 
  male 
  is 
  winged, 
  the 
  female 
  apterous 
  and 
  very 
  obese 
  in 
  form. 
  The 
  antennae 
  are 
  

   10-jointed; 
  the 
  mandibles 
  are 
  prominent, 
  and 
  the 
  last 
  joint 
  of 
  the 
  maxillary 
  palpi 
  is 
  

   elongate 
  and 
  not 
  impressed. 
  The 
  thorax 
  is 
  short, 
  not 
  narrowed 
  at 
  the 
  base. 
  The 
  

   spurs 
  of 
  the 
  posterior 
  tibiae 
  are 
  free 
  in 
  both 
  sexes 
  : 
  the 
  claws 
  are 
  long 
  and 
  slender 
  and 
  

   are 
  armed 
  with 
  a 
  sharp 
  tooth 
  near 
  the 
  base.
