  Three 
  specimens. 
  

  

  Almost 
  certainly 
  the 
  male 
  of 
  E. 
  innotnta, 
  Turn., 
  which 
  

   was 
  taken 
  in 
  considerable 
  numbers 
  at 
  the 
  same 
  time. 
  

   E. 
  heterogamia, 
  Sauss., 
  a 
  larger 
  species, 
  also 
  occurs 
  more 
  

   sparingly 
  in 
  the 
  same 
  locality. 
  

  

  Very 
  near 
  E. 
  asmarensis, 
  Turn., 
  but 
  the 
  second 
  and 
  third 
  

   dorsal 
  segments 
  are 
  more 
  elongate 
  in 
  the 
  present 
  species, 
  the 
  

   third 
  abscissa 
  of 
  the 
  radius 
  is 
  longer, 
  and 
  the 
  seventh 
  dorsal 
  

   segment 
  is 
  without 
  a 
  carina.
