  broader 
  than 
  the 
  femora, 
  very 
  swollen 
  on 
  each 
  side, 
  and 
  as 
  broad 
  

   at 
  the 
  compressed 
  apical 
  part 
  as 
  at 
  the 
  middle, 
  sharply 
  spinose 
  

   on 
  each 
  side 
  of 
  the 
  apex, 
  but 
  not 
  mucronate, 
  and 
  having 
  a 
  distinct 
  

   apical 
  spur, 
  hind 
  tarsi 
  contracted, 
  very 
  massive 
  and 
  glabrous, 
  the 
  

   fourth 
  produced 
  inwardly 
  into 
  a 
  slightly 
  bifid 
  process, 
  fifth 
  longer 
  

   than 
  the 
  whole 
  of 
  the 
  four, 
  very 
  massive 
  and 
  very 
  distinctly 
  

   bi-dentate 
  underneath, 
  hind 
  claw 
  robust, 
  simple. 
  The 
  shape 
  of 
  the 
  

   hind 
  legs 
  is 
  almost 
  similar 
  to 
  that 
  of 
  H. 
  arthriticus, 
  but 
  there 
  is 
  an 
  

   apical 
  spur 
  wanting 
  in 
  the 
  latter, 
  and 
  the 
  fifth 
  joint 
  of 
  the 
  hind 
  

   tarsi 
  is 
  distinctly 
  bi-dentate 
  instead 
  of 
  having 
  one 
  bifid 
  tooth. 
  

  

  Female 
  : 
  The 
  female 
  is 
  exactly 
  like 
  that 
  of 
  H. 
  arthriticus.

  n. 
  spec. 
  

  

  Very 
  closely 
  allied 
  to 
  H. 
  insignis. 
  

  

  Male 
  : 
  Black, 
  with 
  only 
  the 
  abdomonial 
  segments 
  edged 
  with 
  

   flavescent 
  scales, 
  a 
  few 
  of 
  which 
  are 
  also 
  seen 
  on 
  the 
  sides 
  of 
  the 
  

   metasternum 
  ; 
  the 
  elytra 
  are 
  very 
  dark 
  fuscous 
  brown, 
  densely 
  but 
  

   very 
  briefly 
  pubescent, 
  they 
  have 
  no 
  trace 
  of 
  scales, 
  and 
  they 
  are 
  

   neither 
  striate 
  nor 
  costulate 
  ; 
  the 
  hind 
  femora 
  are 
  similarly 
  shaped, 
  

   but 
  they 
  are 
  not 
  quite 
  as 
  much 
  swollen 
  ; 
  the 
  apical 
  spur 
  is 
  identical. 
  

  

  This 
  insect 
  may 
  prove 
  to 
  be 
  a 
  varietal 
  form 
  of 
  H. 
  insignis.

  is 
  sinuate, 
  at 
  the 
  apex 
  there 
  is 
  

   a 
  short 
  but 
  sharp 
  mucro 
  bearing 
  an 
  apical 
  spur,
