  In 
  addition 
  to 
  the 
  type, 
  I 
  have 
  seen 
  a 
  female 
  specimen 
  taken 
  by 
  

   C. 
  W. 
  Johnson 
  at 
  Fort 
  Kent, 
  Maine, 
  August 
  19, 
  1910, 
  which, 
  fol- 
  

   lowing 
  comparison 
  with 
  the 
  type, 
  I 
  designated 
  a 
  homotype. 
  This 
  

   specimen 
  is 
  in 
  the 
  collection 
  of 
  the 
  Boston 
  Society 
  of 
  Natural 
  

   History. 
  It 
  differs 
  from 
  the 
  type 
  only 
  in 
  having 
  25 
  instead 
  of 
  28 
  

   segments 
  in 
  the 
  antennae, 
  and 
  in 
  having 
  the 
  parts 
  that 
  are 
  testaceous 
  

   in 
  the 
  type, 
  reddish 
  or 
  reddish-brown. 
  Mr. 
  Johnson 
  has 
  taken 
  two 
  

   other 
  female 
  specimens 
  of 
  this 
  species, 
  at 
  Southwest 
  Harbor 
  and 
  

   Mount 
  Desert, 
  Maine, 
  respectively. 
  He 
  has 
  very 
  kindly 
  presented 
  

   one 
  of 
  these 
  to 
  the 
  National 
  Museum.
