   diameter 
  of

  Looking 
  from 
  above, 
  

   with 
  ordinary 
  lens-power, 
  these

  all 
  springing 
  

   from 
  a 
  prominent, 
  dark

  which 
  occu- 
  

   jjies 
  the 
  basal 
  half 
  of 
  the 
  joint 
  beneath,, 
  

   and 
  gives 
  a 
  somewhat 
  serrate

  A 
  microscopic 
  examination 
  shows 
  the 
  Tenation 
  in 
  vernata 
  to 
  be 
  on 
  the 
  same 
  plan 
  as 
  that 
  in 
  pome- 
  

   taria. 
  The 
  difference 
  is 
  that 
  in 
  vernata 
  the 
  costal 
  vein 
  is 
  feeble 
  and 
  f^enerally 
  obsolete 
  at 
  its 
  termina, 
  

   tion, 
  and 
  all 
  the 
  veins 
  7-12 
  are 
  more 
  closely 
  united 
  with 
  the 
  costal 
  than 
  inpometaria.
