  shorter 
  tooth 
  is 
  more 
  than 
  half 
  the 
  length 
  of 
  the 
  other 
  (jyilosulus) 
  

   or 
  nearly 
  as 
  long 
  (neglectus, 
  vanus) 
  and 
  slightly 
  cleft 
  at 
  the 
  tip. 
  

  

  Burmeister 
  has 
  seen 
  only 
  one 
  example 
  of 
  this 
  genus, 
  and 
  did 
  not 
  

   dissect 
  the 
  mouth 
  parts, 
  perhaps 
  he 
  was 
  not 
  allowed 
  to 
  do 
  so. 
  This 
  

   would 
  account 
  for 
  the 
  discrepancy 
  between 
  his 
  description 
  and 
  mine. 
  

   My 
  example, 
  however, 
  came 
  from 
  Drege, 
  and 
  I 
  have 
  some 
  reason 
  to 
  

   believe 
  that 
  it 
  is 
  the 
  identical 
  female 
  examined 
  by 
  Burmeister. 
  

  

  This 
  genus 
  is 
  very 
  well 
  characterised 
  by 
  the 
  peculiar 
  shape 
  of 
  the 
  

   mentum 
  and 
  by 
  the 
  tibiae 
  being 
  bi-carinate 
  on 
  the 
  upper 
  side. 
  It 
  is 
  

   purely 
  South 
  African.
