  one 
  of 
  the 
  labial 
  is 
  a 
  little 
  longer 
  ; 
  the 
  maxillae 
  are 
  robust 
  and 
  

   produced 
  at 
  the 
  apex 
  into 
  a 
  laminate, 
  somewhat 
  hollow 
  process, 
  

   curving 
  and 
  rounded 
  at 
  the 
  top 
  and 
  having 
  at 
  its 
  base 
  three 
  sharp 
  

   horizontal 
  teeth 
  ; 
  clypeus 
  nearly 
  as 
  long 
  as 
  the 
  head, 
  sub-parallel, 
  

   truncate 
  at 
  the 
  tip 
  ; 
  prothorax 
  longer 
  than 
  in 
  Pojpillia 
  and 
  also 
  

   narrower, 
  a 
  little 
  ampliate 
  laterally 
  in 
  the 
  middle, 
  sinuate 
  past 
  the 
  

   median 
  part 
  and 
  marginate 
  all 
  round 
  ; 
  scutellum 
  somewhat 
  rounded 
  

   at 
  the 
  apex 
  ; 
  elytra 
  a 
  little 
  more 
  elongate 
  than 
  in 
  Popillia, 
  pygidium 
  

   and 
  legs 
  similar 
  ; 
  mesosternum 
  without 
  a 
  projecting 
  process. 
  

  

  This 
  genus 
  was 
  indicated 
  rather 
  than 
  characterised 
  by 
  Erikson 
  for 
  

   a 
  Senegal 
  species, 
  owing 
  to 
  the 
  curious 
  form 
  of 
  its 
  maxillae. 
  Dr. 
  G. 
  

   Kraatz, 
  in 
  his 
  Monographic 
  Eevision 
  of 
  the 
  Rutelid 
  Genus 
  Popillia,, 
  

   has 
  given 
  a 
  fuller 
  description 
  of 
  the 
  generic 
  difference. 
  

  

  Another 
  species 
  is 
  known 
  from 
  the 
  Gold 
  Coast.

  Head 
  and 
  prothorax 
  metallic 
  green, 
  shining 
  ; 
  elytra 
  straw-colour, 
  

   with 
  a 
  narrow 
  sutural 
  and 
  marginal 
  bronze 
  band, 
  as 
  well 
  as 
  a 
  

   humeral 
  patch, 
  and 
  a 
  somewhat 
  dark 
  but 
  not 
  infuscate 
  median 
  band 
  

   on 
  each 
  side, 
  this 
  band 
  is 
  at 
  times 
  partly 
  obliterated, 
  under 
  side 
  dark 
  

   bronze, 
  antennae, 
  with 
  the 
  exception 
  of 
  the 
  club 
  which 
  is 
  black, 
  palpi, 
  

   and 
  legs 
  ferruginous 
  ; 
  the 
  elytra 
  only 
  are 
  glabrous, 
  the 
  rest 
  of 
  the 
  

   body, 
  including 
  the 
  legs 
  and 
  the 
  whole 
  pygidium, 
  is 
  covered 
  with 
  a 
  

   dense, 
  flavescent 
  villose 
  pubescence 
  ; 
  head 
  very 
  rugose, 
  clypeus 
  as 
  

   long 
  as 
  broad, 
  truncate 
  in 
  front, 
  with 
  the 
  angles 
  slightly 
  rounded, 
  

   and 
  slightly 
  ampliated 
  in 
  the 
  median 
  part 
  of 
  the 
  sides 
  ; 
  prothorax 
  

   finely 
  marginate 
  except 
  in 
  the 
  median 
  part 
  of 
  the 
  base, 
  which 
  is 
  

   emarginate 
  above 
  the 
  scutellum, 
  covered 
  with 
  deep, 
  closely 
  set 
  

   punctures, 
  and 
  having 
  a 
  very 
  distinct 
  median 
  longitudinal 
  sulcus 
  

   interrupted 
  in 
  the 
  centre 
  ; 
  elytra 
  slightly 
  longer 
  than 
  broad, 
  sinuate 
  

   laterally 
  in 
  the 
  anterior 
  part, 
  and 
  ampliated 
  for 
  a 
  short 
  distance 
  at 
  

   about 
  the 
  median 
  part, 
  impressed 
  transversely 
  below 
  the 
  scutellum, 
  

   the 
  humeral 
  and 
  the 
  apical 
  callus 
  are 
  very 
  distinct, 
  the 
  striae 
  are 
  

   deeply 
  punctured 
  and 
  the 
  intervals 
  are 
  plane 
  in 
  the 
  dorsal 
  part, 
  and 
  

   impunctate 
  ; 
  pygidium 
  scabroso-punctate 
  and 
  completely 
  covered 
  

   with 
  the 
  appressed 
  hairs 
  ( 
  ? 
  ) 
  . 
  

  

  Length 
  9 
  mm. 
  ; 
  width

  mm.

  In 
  this 
  species 
  the 
  infuscate 
  bands 
  on 
  the 
  elytra 
  varies 
  very 
  much 
  ; 
  

   nearly 
  wanting 
  in 
  some 
  examples, 
  they 
  are 
  very 
  conspicuous 
  in 
  

   others, 
  and 
  reach 
  from 
  base 
  to 
  apex.
