  of 
  X. 
  frontalis 
  Olivier, 
  which 
  has 
  "the 
  first 
  three 
  or 
  four 
  segments 
  of 
  

   the 
  abdomen 
  ferruginous, 
  with 
  their 
  apical 
  margins 
  more 
  or 
  less 
  

   broadly 
  black" 
  (Smith). 
  All 
  the 
  Honduras 
  specimens 
  have 
  the 
  abdo- 
  

   men 
  entirely 
  black, 
  and 
  I 
  am 
  willing 
  to 
  consider 
  X. 
  jabricii 
  a 
  distinct 
  

   species. 
  

  

  Perez 
  (1901) 
  gives 
  an 
  account 
  of 
  X. 
  frontalis 
  Olivier, 
  with 
  which 
  he 
  

   includes 
  X. 
  fahricii. 
  Perez 
  records 
  the 
  variations 
  in 
  the 
  color 
  of 
  the 
  

   wings 
  observed 
  by 
  him, 
  as 
  follows: 
  

  

  (1) 
  Wings 
  very 
  brightly 
  colored, 
  greenish 
  bronze, 
  more 
  or 
  less 
  coppery 
  (Chiriqul, 
  

   Guayaquil, 
  Pard). 
  

  

  (2) 
  Wings 
  greenish 
  blue 
  (Pard). 
  

  

  (3) 
  Wings 
  uniform 
  violet-blue 
  (Chiriquf). 
  

  

  (4) 
  Wings 
  uniform 
  violet-purple 
  (Parand). 
  

  

  I 
  thought 
  that 
  these 
  must 
  represent 
  a 
  series 
  of 
  closely 
  allied 
  species, 
  

   but 
  I 
  find 
  that 
  the 
  specimens 
  of 
  X. 
  fahricii 
  from 
  Zamorano 
  fall 
  into 
  

   three 
  series, 
  which, 
  so 
  far 
  as 
  I 
  can 
  see, 
  are 
  structurally 
  identical. 
  It 
  

   is 
  possible 
  that 
  the 
  males 
  might 
  show 
  structural 
  differences. 
  The 
  

   three 
  forms 
  are 
  as 
  follows: 
  

  

  (1) 
  Wings 
  shining 
  dark 
  green, 
  the 
  region 
  beyond 
  the 
  cells 
  blackish. 
  This 
  is 
  

   probably 
  the 
  typical 
  X, 
  fahricii. 
  

  

  (2) 
  Wings 
  uniformly 
  rich 
  purple; 
  rather 
  larger 
  than 
  the 
  others. 
  Variety 
  

   purpureipennis, 
  new. 
  The 
  type 
  from 
  Zamorano, 
  February 
  7. 
  Also 
  taken 
  October 
  

   4 
  (G. 
  Vidales). 
  Type: 
  U.S.N.M. 
  No. 
  58893. 
  

  

  (3) 
  Wings 
  dark, 
  obscurely 
  purplish, 
  with 
  no 
  green. 
  Variety 
  cbscuripennis, 
  new. 
  

   Type 
  from 
  Zamorano, 
  February 
  7 
  (A. 
  Pel6n). 
  Also 
  December 
  29. 
  Type: 
  

   U.S.N.M. 
  No. 
  58894. 
  

  

  Comparing 
  the 
  types 
  of 
  the 
  two 
  varieties 
  I 
  have 
  named, 
  that 
  of 
  

   purpureipennis 
  is 
  more 
  robust 
  with 
  a 
  conspicuously 
  broader 
  abdomen, 
  

   but 
  the 
  anterior 
  wings 
  of 
  obscuripennis 
  are 
  very 
  long, 
  fully 
  23 
  mm. 
  

  

  Mauricio 
  Salazar 
  found 
  at 
  Zamorano 
  a 
  very 
  large 
  black 
  asilid 
  fly, 
  

   looking 
  just 
  like 
  the 
  black 
  bees 
  such 
  as 
  X. 
  fahricii. 
  Dr. 
  Maurice 
  T. 
  

   James 
  says 
  it 
  is 
  Mallophora 
  belzebul 
  Schiner, 
  and 
  it 
  is 
  widely 
  distrib- 
  

   uted, 
  from 
  Texas 
  to 
  Brazil. 
  

  

  XYLOCOPA 
  WILMATTAE 
  Cockerell 
  

  

  This 
  species 
  was 
  described 
  from 
  Guatemala 
  City. 
  I 
  have 
  a 
  couple 
  

   collected 
  by 
  Amado 
  Pelen 
  at 
  Antigua, 
  Guatemala. 
  It 
  is 
  common 
  at 
  

   Zamorano, 
  Honduras, 
  flying 
  with 
  the 
  similar 
  species 
  recorded 
  above. 
  

   We 
  still 
  lack 
  the 
  male.
