  Mentum 
  very 
  elongate, 
  sub-parallel, 
  or 
  elongato-ovate

  more 
  

   than 
  half 
  the 
  length, 
  then 
  much 
  narrowed, 
  parallel, 
  rounded 
  at 
  tip, 
  

   more 
  or 
  less 
  sharply

  ligula 
  

   divided 
  into 
  two 
  parallel 
  long 
  membranaceous 
  narrow 
  lobes, 
  labial 
  

   palpi 
  inserted 
  in 
  two 
  broad 
  but 
  nearly 
  contiguous 
  cavities 
  divided 
  

   only 
  by 
  a 
  narrow 
  interval, 
  the 
  basal 
  joint 
  is 
  short, 
  the 
  second 
  is 
  

   slightly 
  longer, 
  the 
  third 
  is 
  a 
  little 
  longer 
  than 
  these 
  two

  is 
  sub-cylindrical 
  and 
  moderately 
  blunt

  thick, 
  somewhat 
  

   long 
  fulvous 
  pubescence 
  ; 
  maxillary 
  palpi 
  moderately 
  long, 
  apical 
  

   joint 
  shaped 
  like 
  the 
  labial 
  one, 
  but 
  longer 
  ; 
  head 
  carinate 
  laterally, 
  

   clypeus 
  as 
  long 
  as 
  the 
  head, 
  nearly 
  sub-parallel, 
  deeply 
  emarginate 
  

   in 
  the

   covering 
  the 
  whole 
  of 
  the 
  propygidium, 
  pygidium 
  vertical 
  and 
  

   somewhat 
  convex 
  in 
  the 
  male, 
  more 
  sharply 
  triangular 
  and 
  sloping 
  

   in 
  the 
  female 
  ; 
  anterior 
  tibiae 
  with 
  an 
  inner 
  slender 
  spur, 
  tri-dentate 
  

   outwardly 
  with 
  the 
  apical 
  teeth 
  curved 
  and 
  the 
  basal 
  one 
  much 
  

   smaller 
  than 
  the 
  intermediate 
  and 
  nearly 
  obsolete 
  ; 
  hind 
  legs 
  

   similar 
  in 
  both 
  sexes, 
  tarsi

  anterior 
  and 
  posterior 
  tarsi 
  with 
  

   a 
  double 
  unequal 
  claw 
  each 
  branch 
  of 
  which 
  is 
  cleft 
  at 
  the 
  tip, 
  but 
  

   the 
  inner 
  one

  The 
  insects 
  included 
  in 
  this 
  genus 
  are 
  very 
  hairy 
  and 
  covered 
  on 
  

   the 
  upper 
  side, 
  abdomen, 
  and 
  legs 
  with 
  glittering 
  scales 
  more 
  or 
  

   less 
  densely 
  set. 
  They 
  are 
  very 
  abundant 
  at 
  the 
  beginning 
  of 
  the 
  

   spring, 
  especially 
  on 
  heaths. 
  Their 
  habitat 
  does 
  not 
  seem 
  to 
  extend 
  

   as 
  far 
  as 
  Namaqualand, 
  where 
  the 
  kindred 
  flower 
  beetles 
  are 
  sO 
  

   numerous 
  and 
  varied, 
  but 
  they 
  are 
  met 
  with 
  in 
  the 
  Karroo 
  as 
  far
