  This 
  minute 
  species 
  at 
  first 
  sight 
  resembles 
  an 
  Alysiid 
  

   of 
  the 
  genus 
  Aspilota 
  ; 
  it 
  may 
  also 
  be 
  mistaken 
  for 
  

   O. 
  pygvicsator, 
  ajnculator, 
  &c. 
  (spp. 
  3, 
  4) 
  ; 
  it 
  requires 
  a 
  

   microscope 
  for 
  its 
  determination.
