   also 
  a

  of 
  the

  the 
  pygidium 
  are 
  clothed 
  with 
  nearly 
  contiguous, 
  round, 
  

   thick, 
  yellow 
  scales, 
  while 
  only 
  the 
  edges

  Male 
  : 
  Very 
  closely 
  allied 
  to 
  H. 
  sulcatus; 
  the 
  shape 
  is 
  similar 
  

   and 
  also 
  that 
  of 
  the 
  anterior 
  and 
  posterior 
  tibiae 
  ; 
  the 
  elytra 
  have 
  

   also 
  each 
  a 
  juxta-sutural 
  band 
  of 
  yellow 
  or 
  yellowish 
  scales 
  beginning 
  

   at 
  a 
  long 
  distance 
  from 
  the 
  base 
  and 
  rounding 
  the 
  apex, 
  and 
  another 
  

   dorsal 
  one 
  reaching 
  from 
  the 
  base 
  to 
  the 
  median 
  part 
  of 
  the 
  disk, 
  and 
  

   the 
  scutellum 
  is 
  also 
  clothed 
  with 
  somewhat 
  large, 
  round 
  scales, 
  but 
  

   the 
  prothorax 
  is 
  very 
  finely 
  and 
  very 
  closely 
  scabroso-punctate, 
  and 
  

   the 
  median 
  sulcus 
  is 
  less 
  deep, 
  especially 
  in 
  the 
  anterior 
  part. 
  

  

  Female 
  : 
  Black, 
  with 
  the

  ; 
  the 
  punctures 
  on 
  the 
  prothorax 
  are 
  not 
  so 
  closely 
  set 
  as 
  

   in 
  the 
  male, 
  especially 
  along 
  the 
  median 
  groove, 
  and 
  on 
  the 
  elytra 
  

   the 
  two 
  discoidal 
  bands 
  of 
  scales 
  are 
  longer, 
  and 
  there 
  is 
  also 
  an 
  

   outer 
  marginal 
  one 
  round 
  reaching 
  from 
  the 
  apex 
  to 
  humeral 
  part.
