  It 
  does 
  not 
  appear 
  to 
  be 
  E. 
  smaragdina 
  Guerin, 
  which 
  Friese 
  records 
  

   from 
  Costa 
  Rica 
  as 
  E. 
  smaragdina 
  Perty, 
  but 
  I 
  have 
  no 
  material 
  

   for 
  comparison. 
  

  

  EXAERETE 
  M 
  ELANURA. 
  new 
  species 
  

  

  Male. 
  — 
  Length 
  about 
  10 
  mm.; 
  similar 
  in 
  most 
  respects 
  to 
  E. 
  

   bilamellosa 
  Cockerell, 
  but 
  differing 
  thus: 
  Abdomen 
  black, 
  not 
  metallic, 
  

   except 
  that 
  there 
  is 
  a 
  blue 
  band 
  on 
  fourth 
  tergite; 
  the 
  red 
  lobes 
  on 
  

   scutellum 
  shorter 
  and 
  broader; 
  face 
  narrower. 
  The 
  end 
  of 
  the 
  abdomen 
  

   has 
  a 
  pair 
  of 
  widely 
  separated 
  sharp 
  spines. 
  They 
  agree 
  in 
  each 
  

   having 
  a 
  spine 
  on 
  each 
  side 
  of 
  thorax 
  posteriorly. 
  The 
  lower 
  basal 
  

   angle 
  of 
  the 
  very 
  wide 
  second 
  submarginal 
  cell 
  is 
  less 
  pointed 
  than 
  in 
  

   E. 
  bilamellosa. 
  I 
  thought 
  this 
  might 
  be 
  the 
  male 
  of 
  E. 
  bilamellosa, 
  

   but 
  it 
  appears 
  too 
  different 
  for 
  this 
  to 
  be 
  the 
  case.

  The

  Honduras: 
  The 
  type 
  queen 
  was 
  taken 
  at 
  fiowers 
  of 
  a 
  species 
  of 
  

   Compositae, 
  December

  1946, 
  near 
  Agua 
  Amarilla, 
  on 
  the 
  lower 
  

   part 
  of 
  Uyaca 
  Mountain. 
  Seven

  In 
  Franklin's 
  table 
  of 
  queens, 
  this 
  runs 
  to 
  B. 
  wilmattae 
  Cockerell, 
  

   which 
  is 
  not 
  similar. 
  The 
  worker 
  runs 
  to 
  B. 
  ephippiatus 
  Say. 
  One 
  

   worker 
  has 
  a 
  large 
  tuft 
  of 
  white 
  hair 
  on 
  middle 
  of 
  clypeus, 
  but 
  usually 
  

   the 
  hair 
  of 
  the 
  head 
  is 
  all 
  black.
