  With 
  reference 
  to 
  the 
  supposed 
  type 
  of 
  Ploiaria 
  maculata 
  Halde- 
  

   man 
  listed 
  above 
  it 
  is 
  to 
  be 
  said 
  that 
  in 
  Haldeman's 
  first 
  article 
  the 
  

   data 
  for 
  his 
  specimen 
  are 
  given 
  as 
  " 
  Pennsylvania, 
  July," 
  and 
  in 
  

   the 
  second 
  " 
  Pennsylvania, 
  June 
  and 
  July." 
  Uhler 
  tells 
  us 
  : 
  7 
  " 
  Prof. 
  

   Haldeman 
  generously 
  gave 
  me 
  the 
  type 
  of 
  his 
  description," 
  but 
  this 
  

   specimen 
  is 
  the 
  type 
  of 
  the 
  second, 
  not 
  the 
  original 
  description. 
  The 
  

   latter. 
  Haldeman 
  informs 
  us, 
  was 
  mutilated 
  and 
  now 
  probably 
  is 
  lost. 
  

  

  This 
  species, 
  next 
  to 
  erraburtdus, 
  is 
  the 
  commonest 
  of 
  the 
  genus 
  

   in 
  America.

  In 
  addition 
  to 
  the 
  characters 
  mentioned 
  in 
  the 
  key, 
  this 
  species 
  

   has 
  the 
  venter 
  with 
  dense 
  appressed 
  white 
  pile 
  except 
  on 
  numerous 
  

   small 
  round 
  areas 
  at 
  bases 
  of 
  the 
  longer 
  hairs 
  which 
  give 
  it 
  under 
  a 
  

   a 
  moderate 
  magnification 
  the 
  appearance 
  of 
  being 
  spotted. 
  The 
  

   fore 
  coxa 
  is 
  nearly 
  as 
  long 
  as 
  the 
  pronotum, 
  the 
  cross-veins 
  in 
  the 
  

   hind 
  wing 
  form 
  an 
  angulated 
  line, 
  both 
  the 
  veins 
  closing 
  the 
  discal 
  

   cell 
  are 
  curved 
  so 
  that 
  the 
  apex 
  of 
  the 
  cell 
  is 
  drawn 
  out 
  into 
  a 
  rather 
  

   long 
  point, 
  the 
  stigma 
  is 
  spotted 
  beyond 
  the 
  cross- 
  vein 
  (fig. 
  11), 
  and 
  

   the 
  eighth 
  sternite 
  in 
  the 
  male 
  has 
  an 
  obtusely 
  pointed 
  terminal 
  

   process 
  (fig. 
  12). 
  The 
  apical 
  antennal 
  segment 
  is 
  one-third 
  as 
  long 
  

   as 
  preapical. 
  Fore

  and
