  CAINOGENION, 
  new 
  genus 
  

  

  Genotype. 
  — 
  Adelotopus 
  ipsoides 
  Westwood. 
  

  

  Front 
  margin 
  of 
  head 
  not 
  continuous 
  beneath 
  eye, 
  where 
  it 
  is 
  in- 
  

   terrupted 
  by 
  a 
  vertical 
  groove 
  which 
  descends 
  to 
  base 
  of 
  antenna 
  

   but 
  is 
  apparently 
  not 
  an 
  antennal 
  groove. 
  Eyes 
  rounded 
  oval 
  with 
  

   the 
  long 
  axis 
  nearly 
  vertical. 
  Antennae 
  very 
  short, 
  stout, 
  fusiform, 
  

   strongly 
  compressed. 
  That 
  portion 
  of 
  the 
  gena 
  between 
  eye 
  and 
  

   maxillary 
  fissure 
  supporting 
  a 
  large 
  projecting 
  process 
  with 
  a 
  trun- 
  

   cate 
  apex. 
  

  

  Carinate 
  median 
  projection 
  of 
  prosternum 
  strongly 
  depressed 
  

   behind 
  coxae 
  so 
  that 
  posterior 
  extremity 
  is 
  in 
  contact 
  with 
  mesoster- 
  

   num, 
  not 
  raised 
  above 
  it 
  by 
  a 
  vertical 
  edge 
  as 
  in 
  Adelotopus. 
  

  

  Thorax 
  and 
  elytra 
  coarsely 
  and 
  deeply 
  punctured. 
  

  

  Posterior 
  angles 
  of 
  thorax 
  produced 
  posteriorly. 
  

  

  The 
  separation 
  of 
  this 
  genus 
  from 
  Adelotopus 
  was 
  suggested 
  by 
  

   Newman. 
  5 
  It 
  seems 
  abundantly 
  distinct 
  by 
  the 
  characters 
  given 
  

   above. 
  

  

  In 
  the 
  following 
  synopsis 
  such 
  species 
  as 
  could 
  not 
  be 
  identified 
  

   in 
  the 
  material 
  at 
  hand 
  are 
  marked 
  with 
  an 
  asterisk, 
  their 
  position 
  

   being 
  determined 
  from 
  the 
  original 
  description 
  only.
