  which 
  are 
  nearly 
  as 
  large 
  (Sg- 
  millim.) 
  as 
  L. 
  rubricatus. 
  

   The 
  sculj^ture 
  of 
  the 
  elytra 
  and 
  peculiar 
  fine 
  striation 
  of 
  

   the 
  apical 
  portion 
  in 
  the 
  2 
  are 
  the 
  same 
  in 
  both 
  species. 
  

   The 
  acute 
  outstanding 
  hind 
  angles 
  of 
  the 
  thorax 
  are 
  

   also 
  nearly 
  the 
  same, 
  but 
  the 
  thorax 
  is 
  a 
  little 
  longer 
  

   relatively 
  in 
  L. 
  rubricatus. 
  There 
  remains 
  for 
  the 
  chief 
  

   distinctive 
  character 
  the 
  bronzy 
  red 
  vaguely-defined 
  long 
  

   oval 
  spot 
  near 
  the 
  sutural 
  interstices, 
  and 
  the 
  similarly 
  

   coloured 
  apical 
  border 
  and 
  epipleurse.

  This 
  species 
  has 
  previously 
  been 
  recorded 
  from 
  

   Columbia, 
  the 
  Upper 
  Amazons, 
  Para, 
  and 
  Minas 
  Geraes, 
  

   in 
  South 
  Brazil, 
  but 
  not 
  from 
  Central 
  America.

  Specimens 
  of 
  this 
  insect 
  were 
  captured 
  by 
  Herr

   at 
  Kefugio 
  and 
  Ciudad 
  in 
  Durango, 
  Eeal 
  del 
  Monte 
  in 
  

   Hidalgo, 
  and 
  La 
  Noria 
  in 
  Sinaloa. 
  The 
  species 
  was 
  

   doubtfully 
  included 
  by

  the 
  Mexican 
  fauna

   C.

  with 
  constantly 
  paler

  antennse 
  

   and 
  legs. 
  The 
  thorax 
  differs 
  in 
  being 
  broader

   and 
  having 
  rufo-translucent 
  lateral 
  margins. 
  It
