  Zoology 
  which 
  may 
  beloug 
  here 
  (as 
  the 
  cerei 
  indicate), 
  but 
  the 
  tegmina 
  

   are 
  longer 
  than 
  in 
  the 
  specimens 
  described 
  above 
  and 
  the 
  whole 
  appear- 
  

   ance 
  and 
  the 
  proportions 
  are 
  tliose 
  of 
  IT. 
  festivus. 
  

  

  Besides 
  the 
  colorational 
  features 
  which 
  distinguish 
  this 
  species 
  from 
  

   H. 
  viridis, 
  the 
  body 
  is 
  relatively 
  stouter, 
  the 
  antennae 
  coarser 
  and 
  

   shorter 
  in 
  proportion 
  to 
  the 
  pronotura, 
  the 
  latter 
  is 
  more 
  acutely 
  angu- 
  

   late 
  behind 
  (though 
  the 
  difference 
  is 
  bnt 
  slight), 
  the 
  hind 
  femora 
  are 
  

   shorter 
  and 
  stouter, 
  and 
  the 
  tegmina 
  and 
  wings 
  relatively 
  shorter.
