  the

  pale,

  Orbicular 
  rather 
  small, 
  obUque;

  very 
  

   little 
  constricted; 
  outer 
  line 
  bent 
  very 
  nearly 
  at

  The 
  females, 
  above 
  referred 
  to, 
  are 
  redder 
  than 
  the 
  male 
  type, 
  the 
  

   orbicular 
  is 
  larger 
  and 
  more 
  distinctly 
  oblique, 
  the 
  reniform 
  is 
  well 
  

   constricted 
  and 
  the 
  outer 
  line 
  is 
  not 
  bent 
  at 
  a 
  right 
  angle. 
  On 
  

   account 
  of 
  these 
  differences 
  they 
  have 
  not 
  been 
  made 
  cotypes, 
  

   although 
  I 
  think 
  it 
  probable 
  that 
  the 
  differences 
  are 
  varietal 
  only.
