  long, 
  very 
  little 
  attenuate 
  towards 
  the 
  apical 
  part, 
  plane 
  or 
  nearly 
  so 
  

   in 
  the 
  dorsal 
  part, 
  and 
  very 
  little 
  sloping 
  on 
  the 
  sides, 
  punctato-striate 
  

   in 
  the 
  dorsal 
  part 
  and 
  oftener 
  than 
  not 
  punctate 
  only 
  on 
  the 
  sides, 
  

   intervals 
  plane 
  or 
  moderately 
  costate 
  ; 
  the 
  greatest 
  part 
  of 
  the 
  pro- 
  

   pygidiuni 
  is 
  hidden 
  by 
  the 
  elytra, 
  the 
  pygidium 
  is 
  very 
  sloping 
  ; 
  the 
  

   legs 
  are 
  short, 
  robust, 
  the 
  posterior 
  coxae 
  are 
  sharply 
  carinate 
  semi- 
  

   circularly 
  on 
  the 
  outer 
  part 
  and 
  project 
  distinctly 
  beyond 
  the 
  elytra 
  ; 
  

   anterior 
  tibiae 
  bi-dentate, 
  but 
  with 
  the 
  basal 
  tooth 
  very 
  blunt 
  or 
  

   merely 
  angular 
  ; 
  they 
  are 
  carinate 
  on 
  the 
  upper 
  side 
  and 
  have 
  an 
  

   inner 
  apical 
  spur 
  ; 
  the 
  joints 
  of 
  the 
  tarsi 
  are 
  compressed, 
  strongly 
  

   bristly 
  underneath, 
  the 
  fifth 
  joint 
  is 
  as 
  long 
  as 
  the 
  four 
  preceding 
  

   joints 
  taken 
  together 
  ; 
  the 
  claws 
  are 
  hinged, 
  double 
  and 
  parallel, 
  the 
  

   outer 
  one 
  is 
  nearly 
  as 
  long 
  as 
  the 
  inner 
  but 
  a 
  little 
  more 
  slender, 
  and 
  

   the 
  latter 
  is 
  incised 
  in 
  both 
  the 
  anterior 
  and 
  intermediate 
  tarsi 
  in 
  both 
  

   sexes, 
  although 
  in 
  the 
  male 
  the 
  incision 
  is 
  very 
  slight 
  or 
  often 
  

   invisible 
  ; 
  the 
  pygidium 
  has 
  two 
  patches 
  of 
  white 
  hairs 
  or 
  is 
  some- 
  

   times 
  completely 
  hairy, 
  and 
  so 
  are 
  the 
  sides 
  of 
  the 
  abdomen 
  ; 
  the 
  

   prosternum 
  is 
  produced 
  into 
  a 
  compressed 
  aculeate 
  process 
  con- 
  

   spicuous 
  or 
  not 
  ; 
  antennae 
  nine-jointed. 
  

  

  The 
  two 
  sexes 
  are 
  very 
  much 
  alike, 
  but 
  the 
  male 
  is 
  easily 
  identified 
  

   by 
  the 
  broader 
  inner 
  claw 
  of 
  the 
  anterior 
  tarsi. 
  

  

  This 
  genus 
  has 
  only 
  one 
  representative 
  in 
  South 
  Africa, 
  but 
  is 
  

   numerously 
  represented 
  in 
  the 
  rest 
  of 
  Africa. 
  

  

  Herr 
  A. 
  J. 
  Kolbe 
  has 
  divided 
  the 
  genus 
  into 
  several 
  sub-genera 
  

   (Stett. 
  Ent. 
  Zeit., 
  1894, 
  p. 
  207). 
  One 
  of 
  them, 
  Peripopillia, 
  has, 
  I 
  

   think, 
  a 
  generic 
  value, 
  and 
  is 
  retained 
  as 
  such 
  ; 
  but 
  the 
  only 
  dis- 
  

   tinction 
  between 
  Popillia 
  and 
  the 
  genus 
  Nannopopillia 
  created 
  for 
  

   Popillia 
  minuscula, 
  Har., 
  are 
  the 
  shape 
  of 
  the 
  clypeus, 
  the 
  absence 
  of 
  

   a. 
  very 
  projecting 
  mesosternal 
  process, 
  and 
  the 
  fissured 
  inner 
  claw 
  of 
  

   the 
  intermediate 
  tarsi 
  in 
  the 
  male 
  ; 
  the 
  basal 
  part 
  of 
  the 
  pygidium 
  is 
  

   hairy 
  transversely. 
  Mr. 
  Arrow 
  has 
  included 
  in 
  this 
  genus 
  another 
  

   South 
  African 
  species 
  which 
  certainly 
  belongs 
  to 
  Popillia, 
  and 
  in 
  

   which 
  the 
  mesosternum 
  does 
  project, 
  although 
  not 
  quite 
  as 
  much 
  as 
  

   in 
  the 
  species 
  of 
  the 
  Sub-genus 
  Popillia, 
  which 
  has 
  the 
  inner 
  claw 
  of 
  

   the 
  intermediate 
  tarsi 
  also 
  incised 
  in 
  the 
  male. 
  This 
  last 
  character 
  

   is 
  found 
  in 
  Popillia 
  biguttata, 
  although 
  it 
  is 
  not 
  conspicuously 
  

   shown, 
  and 
  I 
  have 
  also 
  met 
  with 
  it 
  in 
  some 
  species 
  from 
  the 
  Gold 
  

   Coast, 
  P. 
  femoralis 
  among 
  others 
  ; 
  the 
  buccal 
  organs 
  are 
  similar 
  to 
  

   those 
  of 
  Popillia, 
  and 
  so, 
  for 
  that 
  matter, 
  are 
  those 
  of 
  Nannopopillia, 
  

   so 
  that 
  the 
  latter' 
  s 
  distinctive 
  characters 
  are 
  after 
  all 
  reduced 
  to 
  the 
  

   slope 
  of 
  the 
  clypeus 
  and 
  the 
  sharper 
  outer 
  teeth 
  of 
  the 
  anterior 
  tibiae. 
  

  

  The 
  species 
  of 
  Popillia 
  are 
  found 
  in 
  and 
  on 
  flowers, 
  and 
  also 
  on 
  

   the 
  trees 
  in 
  daytime.
