  mediate 
  and 
  posterior 
  tibiae 
  instead 
  of 
  one. 
  The 
  claws 
  are 
  equal 
  

   only 
  in 
  the 
  genus 
  PhcBiiomeris 
  where 
  they 
  are 
  also 
  dentate 
  under- 
  

   neath 
  in 
  the 
  four 
  anterior 
  legs 
  in 
  the 
  manner 
  of 
  many 
  MELOLONTHiNiE. 
  

   With 
  the 
  Dynastln^ 
  they 
  are 
  connected 
  by 
  the 
  position 
  of 
  the 
  

   spiracles 
  which 
  is 
  nearly 
  similar. 
  The 
  form 
  of 
  the 
  punctate 
  

   striation 
  on 
  the 
  elytra 
  of 
  many 
  species 
  of 
  Anomala 
  is 
  somewhat 
  

   similar 
  to 
  that 
  found 
  in 
  many 
  species 
  of 
  Dynastin^e. 
  

  

  Most 
  of 
  the 
  South 
  African 
  KuTELiNiE 
  are 
  nocturnal 
  or 
  crepuscular 
  ; 
  

   only 
  a 
  few 
  are 
  found 
  on 
  flowers 
  in 
  daytime. 
  They 
  remain 
  mostly 
  

   hidden 
  in 
  the 
  foliage 
  during 
  the 
  day, 
  but 
  I 
  have 
  found 
  some 
  Adoretus 
  

   buried 
  under 
  a 
  thin 
  layer 
  of 
  earth 
  at 
  the 
  foot 
  of 
  trees 
  during 
  the 
  

   daytime. 
  The 
  specific 
  study 
  of 
  the 
  African 
  species 
  is 
  extremely 
  

   difficult, 
  with 
  a 
  few 
  exceptions 
  in 
  the 
  genus 
  Popillia 
  and 
  kindred 
  

   genera, 
  and 
  on 
  that 
  account 
  I 
  have 
  found 
  a 
  comparison 
  of 
  the 
  genital 
  

   armature 
  of 
  the 
  male 
  most 
  useful, 
  not 
  only 
  for 
  discriminating 
  between 
  

   South 
  African 
  species, 
  but 
  also 
  between 
  those 
  from 
  other 
  African 
  

   localities. 
  

  

  In 
  South 
  Africa 
  we 
  have 
  two 
  aberrant 
  forms 
  ; 
  one 
  has 
  been 
  already 
  

   mentioned 
  — 
  i.e., 
  Phcenomeris 
  — 
  but 
  Isoplia 
  is 
  perhaps 
  still 
  more 
  ab- 
  

   normal 
  owing 
  to 
  its 
  adaptation 
  to 
  a 
  floral 
  life. 
  In 
  that 
  way 
  it 
  has 
  

   acquired 
  characters 
  not 
  unlike 
  those 
  found 
  among 
  the 
  Heterochilus 
  

   of 
  the 
  Sub-Family 
  Hopliin^e, 
  and, 
  as 
  in 
  many 
  of 
  the 
  latter, 
  the 
  upper 
  

   lobe 
  of 
  the 
  maxillae 
  has 
  a 
  pencil 
  of 
  hairs. 
  This 
  is 
  the 
  only 
  instance 
  

   known 
  to 
  me 
  among 
  the 
  Butelin^. 
  

  

  The 
  South 
  African 
  species 
  and 
  genera 
  are 
  divided 
  into 
  four 
  Tribes.
