  marked 
  as 
  the 
  type 
  in 
  the 
  British 
  Museum 
  collection 
  being 
  

   K. 
  julii, 
  Rom., 
  which 
  does 
  not 
  at 
  all 
  agree 
  with 
  the 
  de- 
  

   scription. 
  In 
  Smith's 
  collection 
  I 
  found 
  under 
  the 
  name 
  

   E. 
  elegantulum 
  two 
  specimens 
  of 
  Elis 
  obscurer, 
  Kabr., 
  which 
  

   answer 
  well 
  to 
  the 
  description. 
  I 
  am 
  inclined 
  to 
  think 
  

   that 
  Smith's 
  label 
  must 
  have 
  been 
  shifted 
  accidentally 
  in 
  the 
  

   Museum 
  collection, 
  and 
  that 
  elegantulum 
  should 
  be 
  treated 
  

   as 
  a 
  synonym 
  of 
  Elis 
  obscura, 
  Fabr.
