  Black,

  two 
  bands 
  of 
  white

  band 
  of 
  

   small 
  white 
  round 
  scales 
  not 
  very 
  closely 
  set

  the 
  outer 
  band 
  

   reaches 
  to 
  the 
  median 
  part

  more 
  elongate

  The 
  species 
  which 
  I 
  take 
  to 
  be 
  H. 
  nubilus, 
  and 
  which 
  was 
  labelled 
  

   under 
  this 
  name 
  in 
  Drege's 
  Collection, 
  answers 
  very 
  well 
  to 
  Bur-
