  The 
  genus 
  is 
  new 
  to 
  Formosa. 
  In 
  its 
  broad 
  head 
  this 
  

   resembles 
  A. 
  vitiosa, 
  Smith, 
  from 
  China, 
  but 
  it 
  differs 
  in 
  

   many 
  other 
  respects. 
  There 
  is 
  also 
  evident 
  affinity 
  with 
  the 
  

   European 
  A. 
  labialis, 
  Kirby. 
  1 
  possess 
  only 
  the 
  male 
  of 
  

   labialis, 
  which 
  is 
  considerably 
  larger 
  than 
  that 
  of 
  formosana, 
  

   with 
  the 
  lateral 
  face-marks 
  longer 
  and 
  the 
  abdomen 
  duller 
  

   and 
  much 
  moie 
  hairy. 
  The 
  type 
  of 
  A. 
  formosana 
  is 
  a 
  

   female.
