  only 
  those 
  of 
  the 
  

   lower 
  part 
  of 
  the 
  base 
  being 
  blackened. 
  The 
  extreme 
  base, 
  before 
  the 
  humeral 
  

   cross-vein, 
  is 
  infuscated 
  as 
  a 
  short 
  yellowish

  The 
  basal 
  blackish

  they 
  invade 
  the 
  anal 
  cell 
  also, 
  and 
  even 
  the

  of 
  the 
  stigma 
  to 
  the

  of 
  the 
  sixth 
  longi- 
  

   tudinal 
  vein, 
  but 
  not 
  extending 
  into 
  the 
  axillary 
  cell, 
  or 
  only 
  slightly 
  so 
  ; 
  the 
  small 
  

   cross-vein 
  is 
  placed 
  just 
  at 
  the 
  anterior 
  border 
  of 
  this 
  band. 
  The 
  costal 
  band 
  is 
  

   broadly 
  connected 
  with 
  the 
  basal 
  one, 
  its 
  lower 
  border 
  going 
  exactly 
  along 
  the 
  third 
  

   vein, 
  surpassing 
  it 
  only 
  near 
  the 
  tip
