  Two 
  specimens 
  found 
  near 
  San 
  Diego, 
  on 
  a 
  kind 
  of 
  grass, 
  in 
  June. 
  Similar 
  in 
  all 
  its 
  

   characters 
  to 
  the 
  preceding, 
  but 
  with 
  the 
  sides 
  of 
  the 
  elytra 
  less 
  parallel, 
  and 
  the 
  poste- 
  

   rior 
  angles 
  of 
  the 
  thorax 
  more 
  diverging: 
  the 
  elytra 
  are 
  dirty 
  yellow, 
  with 
  the 
  striae 
  

   brownish: 
  behind 
  the 
  middle 
  is 
  a 
  large, 
  indistinct, 
  blackish 
  cloud, 
  which 
  includes 
  on 
  each 
  

   elytron 
  a 
  transverse 
  slightly 
  rcniform 
  yellow 
  spot, 
  paler 
  than 
  the 
  ground 
  colour 
  of 
  the 
  

   elytra. 
  In 
  one 
  specimen 
  the 
  cloudiness 
  is 
  seen 
  only 
  on 
  the 
  margins 
  of 
  this 
  spot, 
  which 
  is 
  

   also 
  very 
  indistinct.
