  This 
  fine

  is 
  quite 
  distinct 
  from 
  carhonarius, 
  

   Nees 
  (sp. 
  1), 
  and 
  more 
  resembles 
  Wesmaelii, 
  Hal. 
  (sp. 
  8) 
  ; 
  

   it 
  is, 
  however, 
  much 
  larger, 
  and 
  distinguished 
  by 
  the 
  

   colours 
  of 
  the 
  abdomen 
  ; 
  the 
  1st 
  abscissa 
  of 
  the 
  radius 
  

   is 
  also 
  much 
  longer 
  in 
  proportion.

  captured 
  

   many 
  specimens
