  the 
  material 
  examined 
  in 
  this

  consist 
  in«i; 
  of 
  a 
  male 
  para- 
  

   type 
  from 
  Villa 
  Mora, 
  Parajjuay, 
  and 
  a 
  female 
  from 
  Georgetown, 
  

   British 
  Guiana, 
  identified 
  by 
  myself. 
  The 
  latter 
  specimen 
  agrees 
  

   perfectly 
  with 
  the 
  original 
  tlescription. 
  

  

  This 
  is 
  probably 
  synonymous
