  H. 
  coadjutor 
  is 
  probably 
  the 
  male

  H.

  The 
  sexes 
  in 
  

   this 
  genus 
  are 
  often 
  very 
  dissimilar, 
  but 
  there 
  is 
  a 
  certain 
  general 
  

   resemblance 
  between 
  these 
  two 
  types 
  which 
  suggests 
  that 
  they 
  may 
  

   be 
  conspecific. 
  Both 
  come 
  from 
  the 
  same 
  locality.
