  Differs 
  from 
  the 
  last 
  species 
  by 
  the 
  more 
  prominent 
  shoulders 
  

   of 
  the 
  elytra, 
  though 
  these 
  are 
  still 
  cut 
  away 
  somewhat 
  

   obliquely, 
  and 
  by 
  the 
  relatively 
  shorter 
  first 
  joint 
  of 
  the 
  tarsi. 
  

   The 
  vitta? 
  on 
  the 
  vertex 
  are 
  broader; 
  there 
  is 
  a 
  single 
  broad 
  

   vitta 
  on 
  each 
  side 
  of 
  the 
  thorax 
  above 
  instead 
  of 
  two 
  (in 
  one 
  

   of 
  the 
  three 
  specimens 
  each 
  vitta 
  is 
  divided 
  by 
  an 
  incomplete 
  

   narrow 
  black 
  line) 
  ; 
  the 
  s^pots 
  on 
  the 
  elytra 
  are 
  broader 
  and 
  

   more 
  irregular 
  in 
  form. 
  

  

  This 
  species 
  differs 
  from 
  C. 
  cassandra 
  by 
  the 
  less 
  promi- 
  

   nent 
  shoulders, 
  by 
  the 
  A 
  -forming 
  vitta? 
  on 
  the 
  vertex 
  of 
  the 
  

   head, 
  and 
  the 
  absence 
  of 
  the 
  oblique 
  fascia 
  on 
  the 
  side 
  of 
  the 
  

   head, 
  which 
  in 
  cassandra 
  is 
  continuous 
  with 
  the 
  dorso-lateral 
  

   thoracic 
  vitta.

  Prothorax 
  with 
  a 
  rather 
  broad 
  luteous 
  vitta 
  on 
  each 
  side 
  

   above, 
  each 
  vitta 
  continued 
  on 
  to 
  the 
  head 
  in 
  front, 
  and, 
  as 
  a 
  

   less 
  well-defined 
  vitta, 
  for 
  some 
  distance 
  along 
  the 
  middle 
  of 
  

   each 
  elytron 
  behind

   vitta?

  with 
  a 
  supracoxal

  Elytra

  narrowed

  with 
  the 
  shoul-

  extremely 
  oblique 
  and 
  not 
  prominent, 
  so 
  that 
  the 
  sides 
  of 
  

   the 
  elytra 
  form 
  with 
  the 
  sides 
  of 
  the 
  prothorax 
  a 
  continuous 
  

   curve 
  ; 
  with 
  a 
  luteous 
  pubescence, 
  which, 
  except 
  where 
  it 
  

   forms 
  the 
  basal 
  vitta?, 
  is 
  much 
  interrupted
