  A 
  very 
  closely 
  related 
  Crocisa 
  from 
  Foochow, 
  China 
  

   (Caldwell), 
  differs 
  by 
  the 
  much 
  duller, 
  greyish-b\ue 
  of 
  the 
  

   abdominal 
  markings 
  ; 
  the 
  W-like 
  scutellum, 
  without 
  an 
  

   apical 
  blue 
  patch 
  ; 
  the 
  broader 
  median 
  mesothoracic 
  band 
  ; 
  

   the 
  apical 
  band 
  of 
  first 
  abdominal 
  segment 
  very 
  narrowly 
  or 
  

   not 
  interrupted, 
  and 
  joined 
  at 
  sides 
  by 
  a 
  longitudinal 
  band 
  

   to 
  the 
  basal 
  ; 
  and 
  the 
  abundant 
  light 
  hair 
  on 
  the 
  tarsi. 
  

  

  In 
  Friese's 
  table 
  of 
  Oriental 
  and 
  Australian 
  Crocisa 
  (Ann. 
  

   Mus. 
  Nat. 
  Hung. 
  1909) 
  this 
  runs 
  in 
  both 
  sexes 
  straight 
  to 
  

   C. 
  emarginata, 
  but 
  it 
  is 
  certainly 
  not 
  the 
  emaryinata 
  of 
  

   Lepeletier, 
  which 
  has 
  shining 
  blue 
  markings. 
  In 
  my 
  tab'e 
  

   in 
  'Entomologist/ 
  Aug. 
  1910, 
  it 
  runs 
  nearest 
  to 
  C. 
  decora, 
  

   to 
  which 
  it 
  is 
  not 
  closely 
  allied. 
  

  

  It 
  is 
  seen 
  from 
  the 
  above 
  that 
  Formosa 
  contains 
  three 
  

   species 
  of 
  Crocisa, 
  all 
  of 
  different 
  groups. 
  All 
  are 
  close 
  to 
  

   Chinese 
  species, 
  but 
  nevertheless 
  distinct. 
  

  

  Androgynella,

  Like 
  Megachile, 
  but 
  female 
  with 
  13-jointed 
  antennas, 
  and 
  

   ventral 
  surface 
  of 
  abdomen 
  smooth 
  and 
  bare, 
  without 
  any 
  

   trace 
  of 
  a 
  scopa. 
  Junction 
  of 
  third 
  and 
  fourth 
  antennal 
  

   joints 
  in 
  female 
  very 
  oblique. 
  Male 
  with 
  short 
  flattened 
  

   anterior 
  coxal 
  spines 
  or 
  lamellae 
  ; 
  anterior 
  tarsi 
  somewhat 
  

   modified.

  The

  from 
  a 
  single
