  One 
  specimen, 
  north 
  shore 
  of 
  Lake 
  Superior. 
  The 
  front 
  is 
  flat, 
  with 
  the 
  anterior 
  mar- 
  

   gin 
  distinct: 
  it 
  is 
  as 
  finely 
  punctured 
  as 
  the 
  thorax. 
  This 
  species 
  has 
  very 
  much 
  the 
  ap- 
  

   pearance 
  of 
  Cardiophorus, 
  but 
  the 
  prosternal 
  spine 
  is 
  long.

  One 
  specimen, 
  San 
  Jose, 
  California. 
  The 
  lobe 
  of 
  the 
  presternum 
  is 
  longer 
  than 
  in 
  the 
  

   preceding 
  species 
  and 
  more 
  rounded: 
  the 
  general 
  appearance 
  is 
  that, 
  of 
  Adelocera. 
  The 
  

   anterior 
  margin 
  of 
  the 
  front 
  is 
  slightly 
  elevated: 
  the 
  fourth 
  joint 
  of 
  the 
  antenna? 
  is 
  equal 
  

   to 
  the 
  fifth.

  San 
  Diego, 
  California. 
  June, 
  abundant 
  in 
  wet 
  sand. 
  This 
  species 
  resembles 
  the 
  next, 
  

   but 
  the 
  thorax 
  is 
  less 
  elongate, 
  and 
  more 
  suddenly 
  narrowed 
  in 
  front: 
  the 
  scabrous 
  punc- 
  

   tuation 
  is 
  very 
  much 
  coarser: 
  the 
  anterior 
  fascia 
  of 
  the 
  elytra, 
  although 
  dilated 
  externally, 
  

   is 
  never 
  prolonged 
  to 
  the 
  humerus: 
  the 
  femora 
  appear 
  to 
  be 
  always 
  fuscous.

  It 
  is 
  quite 
  possible 
  that 
  this 
  species 
  has 
  been 
  intro- 
  

   duced 
  from 
  Europe: 
  it 
  does 
  not 
  seem 
  to 
  occur 
  far 
  in 
  the 
  interior 
  of 
  the 
  country. 
  The 
  

   fascia 
  of 
  the 
  elytra 
  is 
  composed 
  of 
  a 
  small 
  internal, 
  and 
  an 
  elongate 
  external 
  spot, 
  reach- 
  

   ing 
  from 
  the 
  humerus 
  nearly 
  to 
  the 
  middle. 
  Sometimes 
  the 
  elytra 
  are 
  testaceous, 
  with 
  a 
  

   faint 
  cloudiness 
  behind 
  the 
  middle. 
  In 
  this 
  and 
  the 
  preceding 
  species, 
  the 
  lobe 
  of 
  the 
  pres- 
  

   ternum 
  is 
  large, 
  and 
  separated 
  from 
  the 
  sternum 
  by 
  a 
  strong 
  transverse 
  carina.
