   to 
  C 
  decora, 
  Smith, 
  to 
  which 
  it 
  is 
  very 
  closely 
  allied. 
  Com- 
  

   pared 
  with 
  a 
  Singapore 
  example 
  of 
  decora, 
  it 
  differs 
  as 
  

   follows 
  : 
  markings 
  a 
  little 
  lighter, 
  with 
  a 
  faint 
  greenish 
  

   shade, 
  occasionally 
  almost 
  white 
  ; 
  basal 
  band 
  of 
  first 
  abdo- 
  

   minal 
  segment 
  very 
  thick 
  in 
  middle, 
  projecting 
  from 
  beneath 
  

   scutellum, 
  but 
  sublaterally 
  interrupted 
  or 
  much 
  narrowed 
  

   (in 
  decora 
  thick 
  and 
  even, 
  with 
  a 
  linear 
  median 
  interruption) 
  ; 
  

   sublateral 
  discal 
  spots 
  of 
  thorax 
  smaller.

  I 
  have 
  before 
  me 
  37 
  males 
  and 
  27 
  females 
  ; 
  the 
  type 
  is 
  a 
  

   male 
  from 
  Takao.

  This 
  is 
  a 
  blue-marked 
  species, 
  with 
  the 
  hind 
  femora 
  of 
  the 
  

   male 
  bearing 
  a 
  large, 
  sharp, 
  thorn-like 
  tooth, 
  in 
  all 
  respects 
  

   very 
  close 
  to 
  the 
  mainland 
  C. 
  decora. 
  I 
  should 
  have 
  thought 
  

   it 
  a 
  variety 
  of 
  decora, 
  had 
  I 
  received 
  only 
  a 
  single 
  specimen, 
  

   but 
  the 
  very 
  long 
  series 
  holds 
  its 
  characters 
  well, 
  slight 
  as 
  

   they 
  are. 
  In 
  the 
  ' 
  Entomologist/ 
  1910, 
  p. 
  219, 
  I 
  expressed 
  

   some 
  fear 
  that 
  1 
  might 
  not 
  have 
  correctly 
  identified 
  decora 
  ; 
  

   but 
  since 
  then 
  Mr. 
  Meade-Waldo 
  has 
  examined 
  Smith's 
  type 
  

   (a 
  female 
  from 
  N. 
  China) 
  for 
  me, 
  and 
  returns 
  to 
  me 
  one 
  of 
  

   the 
  specimens 
  from 
  Singapore 
  I 
  had 
  considered 
  decora, 
  

   assuring 
  me 
  that 
  it 
  is 
  a 
  true 
  exponent 
  of 
  the 
  species. 
  

   Mr. 
  Meade-Waldo 
  adds: 
  "decora 
  is 
  certainly 
  marked 
  with 
  

   strong, 
  dark 
  blue 
  (not 
  the 
  pallid 
  wash 
  of 
  Transcaspian 
  

   specimens 
  of 
  the 
  genus 
  Crocisa) 
  ; 
  the 
  bands 
  on 
  the 
  abdomen, 
  

   viewed 
  from 
  above, 
  almost 
  meet 
  (rather 
  more 
  so 
  than 
  in 
  

   Singapore 
  specimen) 
  ; 
  the 
  mesothoracic 
  spots 
  are 
  far 
  from 
  

   the 
  prothoracic 
  band, 
  a 
  line 
  drawn 
  through 
  the 
  extreme 
  

   anterior 
  edge 
  of 
  the 
  tegulae 
  would 
  just 
  pass 
  through 
  the 
  

   hinder 
  edge 
  of 
  the 
  mesothoracic 
  spots."
