  The 
  color 
  pattern 
  of 
  the 
  head 
  and 
  thorax 
  nearly 
  throughout 
  the 
  

   genus 
  is 
  so 
  similar 
  as 
  to 
  constitute 
  almost 
  a 
  generic 
  character. 
  In 
  

   order 
  to 
  avoid 
  much 
  repetition 
  a 
  description 
  of 
  what 
  may 
  be 
  called 
  

   the 
  normal 
  or 
  basic 
  color 
  pattern 
  is 
  gi\en 
  here. 
  In 
  the 
  specific 
  descrip- 
  

   tions 
  only 
  variations 
  from 
  this 
  pattern 
  are 
  indicated.
