  propygidium 
  ; 
  pygidium 
  sub-vertical 
  in 
  both 
  sexes, 
  abdomen 
  not 
  

   contracted 
  ; 
  anterior 
  tibiae 
  tri-dentate 
  outwardly, 
  with 
  the 
  teeth 
  

   nearly 
  equi-distant 
  and 
  oblique, 
  sharply 
  truncate 
  inwardly 
  and 
  

   having 
  an 
  apical 
  spur 
  in 
  the 
  female 
  only, 
  legs 
  slender, 
  moderately 
  

   long, 
  tarsi 
  as 
  long 
  as 
  the 
  tibiae 
  or 
  nearly 
  so, 
  the 
  four 
  anterior 
  claws 
  

   double, 
  unequal, 
  slightly 
  cleft 
  at 
  the 
  tip, 
  and 
  divaricating 
  more 
  than 
  

   in 
  the 
  other 
  genera 
  of 
  this 
  tribe, 
  hind 
  ones 
  single, 
  simple, 
  long 
  and 
  

   not 
  very 
  robust. 
  

  

  This 
  genus 
  differs 
  from 
  Hoplia 
  in 
  the 
  parabolic 
  shape 
  of 
  the 
  clypeus 
  

   and 
  the 
  ten-jointed 
  antennae 
  in 
  both 
  sexes 
  ; 
  and 
  in 
  the 
  legs 
  having 
  

   an 
  apical 
  spur 
  in 
  the 
  female 
  ; 
  unlike 
  Hoplia 
  the 
  body 
  has 
  no 
  scales, 
  

   but 
  sometimes 
  short 
  squamose 
  hairs, 
  and 
  the 
  general 
  appearance 
  

   reminds 
  one 
  of 
  some 
  species 
  of 
  Adorctus. 
  Several 
  Madagascar 
  

   species, 
  Hoplia 
  plagulata, 
  Fairm., 
  among 
  others, 
  will 
  probably 
  be 
  

   included 
  in 
  this 
  genus.
