  Related 
  to 
  A. 
  virescens 
  Fabricius, 
  but 
  abdomen 
  pure 
  black, 
  without 
  

   white 
  hair 
  on 
  apices 
  of 
  tergites. 
  This 
  appears 
  to 
  be 
  the 
  form 
  regarded 
  

   by 
  Vachal 
  as 
  the 
  female 
  of 
  A. 
  nasuius 
  Smith, 
  but 
  the 
  dusky 
  wings, 
  with 
  

   dark 
  nervures, 
  and 
  dull 
  mesonotum 
  indicate 
  that 
  this 
  is 
  another 
  

   species. 
  

  

  AGAPOSTEMON 
  NASUTUS 
  Smith 
  

  

  Male. 
  — 
  Easily 
  distinguished 
  by 
  the 
  peculiar 
  clypeus, 
  the 
  upper 
  

   margin 
  of 
  which 
  is 
  broadly 
  upturned 
  like 
  a 
  hog's 
  snout 
  ; 
  flagellum 
  light 
  

   yellow 
  beneath, 
  with 
  the 
  last 
  two 
  joints 
  black; 
  head 
  and 
  thorax 
  

   bright 
  green; 
  legs 
  yellow; 
  abdomen 
  yellow 
  with 
  six 
  black 
  bands. 
  

  

  Female. 
  — 
  Green, 
  including 
  abdomen, 
  which 
  has 
  broad 
  bands 
  of 
  

   whitish 
  tomentum 
  at 
  bases 
  of 
  tergites 
  2 
  to 
  4. 
  Anterior 
  tibiae 
  mainly 
  

   reddish 
  in 
  front, 
  middle 
  tibiae 
  with 
  a 
  reddish 
  mark 
  anteriorly 
  at 
  end, 
  

   hind 
  tibiae 
  black 
  (A. 
  proscriptus 
  Cockerell, 
  from 
  Guatemala 
  City, 
  

   has 
  the 
  tibiae 
  and 
  tarsi 
  ferruginous). 
  The 
  female 
  is 
  extremely 
  similar 
  

   to 
  A. 
  cockerelli 
  Crawford, 
  but 
  the 
  base 
  of 
  metathorax 
  is 
  granular, 
  not 
  

   evidently 
  striate. 
  The 
  sixth 
  tergite 
  is 
  black 
  haired 
  right 
  across.

  The 
  species 
  here 
  recognized 
  as 
  A. 
  nasutus 
  female 
  is 
  not 
  that 
  of 
  

   Vachal, 
  but 
  it 
  flies 
  with 
  the 
  very 
  distinctive 
  male; 
  and 
  resembles 
  it 
  in 
  

   the 
  paUid 
  wings.
