  Burmeister 
  in 
  his 
  description 
  says 
  that 
  the 
  elytra 
  are 
  concolorous. 
  

   In 
  the 
  two 
  female 
  examples 
  which 
  I 
  have 
  seen 
  the 
  black 
  patches 
  and 
  

   bands 
  on 
  the 
  elytra 
  are 
  nearly 
  obliterated. 
  

  

  Sub-Family 
  HOPLINIIN^. 
  

  

  Body 
  partly 
  or 
  entirely 
  clothed 
  with 
  scales, 
  squamose 
  hairs, 
  

   seldom 
  with 
  simple 
  hairs 
  ; 
  labrum 
  sub-horizontal 
  or 
  vertical, 
  ligula 
  

   bi-lobate 
  and 
  projecting 
  freely 
  beyond 
  the 
  mentum 
  (Pachycncmini) 
  

   or 
  fused 
  with 
  the 
  mentum 
  (Hopliini), 
  maxillae 
  dentate 
  or 
  simple, 
  

   often 
  with 
  a 
  broad 
  membranaceous 
  border 
  ; 
  antennas 
  nine- 
  or 
  ten- 
  

   jointed, 
  club 
  never 
  very 
  long, 
  tri-jointed, 
  the 
  joints 
  fitting 
  against 
  each 
  

   other 
  ; 
  elytra 
  seldom 
  convex, 
  never 
  covering 
  the 
  pygidium, 
  which 
  is 
  

   either 
  vertical 
  or 
  strongly 
  sloping 
  in 
  a 
  forward 
  direction 
  ; 
  abdomen 
  

   sometimes 
  very 
  compressed 
  laterally 
  ; 
  spiracles 
  similar 
  to 
  those 
  of 
  the 
  

   Melolonthin^: 
  ; 
  hind 
  tibiae 
  without 
  spurs 
  or 
  with 
  one 
  spur 
  only 
  ; 
  

   claws 
  single 
  or 
  double, 
  unequal 
  except 
  in 
  the 
  genus 
  DicJielus, 
  cleft 
  

   or 
  simple, 
  the 
  smaller 
  one 
  usually 
  pressed 
  against 
  the 
  larger 
  which 
  

   is 
  articulated 
  as 
  in 
  the 
  Sub-Family 
  Kutblin^e 
  ; 
  hind 
  femora 
  without 
  

   oblique 
  rows 
  of 
  bristles 
  on 
  the 
  outer 
  face. 
  

  

  This 
  Sub-Family 
  can 
  be 
  divided 
  into 
  two 
  distinct 
  Tribes 
  owing 
  to 
  

   the 
  shape 
  of 
  the 
  ligula. 
  

  

  Ligula 
  free, 
  membranaceous, 
  bi-lobate 
  Pachycnemini. 
  

  

  Ligula 
  horny, 
  fused 
  with 
  the 
  mentum 
  Hopliini. 
  

  

  The 
  last-named 
  Tribe 
  can 
  be 
  also 
  divided 
  into 
  three 
  groups 
  owing 
  

   to 
  the 
  shape 
  of 
  the 
  labrum 
  and 
  of 
  the 
  abdomen, 
  or 
  of 
  both 
  of 
  them 
  

   combined.
