  or 
  rows 
  of 
  bristles 
  outwardly 
  ; 
  tarsi 
  a 
  little 
  compressed, 
  

   moderately 
  long, 
  and 
  somewhat 
  robust, 
  claws 
  diverging, 
  equal 
  in 
  

   length, 
  and 
  having 
  underneath 
  in 
  the 
  anterior 
  and 
  intermediate 
  tarsi 
  

   a 
  tooth 
  not 
  as 
  long, 
  but 
  nearly 
  as 
  much 
  curved 
  as 
  the 
  claw 
  itself, 
  but 
  

   simple, 
  slender, 
  and 
  not 
  diverging, 
  and 
  of 
  equal 
  length 
  in 
  the 
  

   posterior 
  tarsi 
  ; 
  hind 
  tibiae 
  gradually 
  dilated 
  from 
  base 
  to 
  apex, 
  

   strongly 
  ciliate 
  there, 
  almost 
  lobate 
  inwardly 
  at 
  the 
  apex, 
  and 
  having 
  

   a 
  dense, 
  inner 
  fringe 
  of 
  hairs 
  in 
  the 
  male, 
  and 
  provided 
  with 
  two 
  

   long 
  apical 
  inner 
  spurs 
  in 
  both 
  sexes. 
  

  

  This 
  aberrant 
  genus 
  of 
  the 
  Butelince 
  is 
  the 
  only 
  one 
  in 
  which 
  the 
  

   claws 
  of 
  the 
  anterior 
  and 
  intermediate 
  tarsi 
  are 
  diverging 
  and 
  have 
  

   underneath 
  a 
  strong 
  tooth, 
  much 
  in 
  the 
  manner 
  of 
  the 
  Melolonthince. 
  

  

  The 
  genus 
  includes 
  three 
  species, 
  two 
  of 
  which 
  are 
  from 
  the 
  

   Sudan 
  ; 
  one 
  of 
  these 
  is 
  also 
  met 
  with 
  in 
  South 
  Africa.
