  The 
  fleshy 
  processes 
  and 
  tubercles 
  which 
  

   surrounded 
  the 
  float 
  in 
  th€ 
  larva 
  are 
  withdrawn 
  anteriorly 
  in 
  the 
  pupa 
  and 
  

   flattened 
  down 
  against 
  the 
  sides 
  of 
  this 
  taillike 
  projection 
  so 
  as 
  to 
  be 
  

   barely 
  distinguishable. 
  

  

  Larvae, 
  pupae 
  and 
  imagos 
  were 
  easy 
  to 
  find 
  through 
  July 
  and 
  August, 
  

   never 
  in 
  open 
  water, 
  and 
  the 
  imagos 
  were 
  not 
  found 
  away 
  from 
  water. 
  

  

  A 
  single 
  parasite 
  bred 
  from 
  a 
  puparium 
  of 
  this 
  species, 
  sent 
  to 
  Mr 
  

   Ashmead 
  for 
  determination, 
  proved 
  to 
  be 
  new 
  to 
  science. 
  At 
  our 
  re- 
  

   quest 
  he 
  has 
  prepared 
  the 
  description 
  of 
  it, 
  given 
  on 
  p. 
  588. 
  Mr 
  Ash- 
  

   mead 
  says 
  he 
  believes 
  that 
  hitherto 
  nothing 
  has 
  been 
  known 
  of 
  the 
  habits 
  

   of 
  wasps 
  of 
  the 
  genus 
  Atractodes.

  I 
  find 
  no 
  published 
  account 
  of 
  the 
  immature 
  stages 
  of 
  any 
  species 
  in 
  

   this 
  large 
  genus, 
  save 
  an 
  antiquated 
  one 
  by 
  Dufour 
  for 
  the 
  European 
  

   species 
  T. 
  ferruginea^. 
  The 
  figures 
  are 
  poor. 
  There 
  is 
  an 
  imago 
  of 
  

   this 
  species, 
  T. 
  pictipes, 
  in 
  the 
  Museum 
  of 
  comparative 
  zoology, 
  

   reared 
  from 
  the 
  pupa 
  by 
  H. 
  G. 
  Hubbard 
  at 
  Milton 
  Mass. 
  Mar. 
  27,

   and 
  another 
  pupa 
  is 
  pinned 
  beside 
  it. 
  I 
  found 
  larvae, 
  pupae 
  and 
  imagos 
  

   common 
  at 
  Saranac 
  Inn, 
  associated 
  in 
  all 
  stages

  The 
  larvae 
  and 
  pupae 
  are 
  similar 
  to 
  the 
  same 
  stages 
  

   inSepedon, 
  but 
  more 
  slender, 
  and 
  with 
  good 
  diflerential 
  characters 
  ; 
  

   they 
  are 
  apparently 
  entirely 
  similar 
  in 
  habits. 
  

  

  The 
  imagos 
  are 
  found 
  in 
  the 
  same 
  bur 
  reed 
  beds, 
  but 
  they 
  rest 
  on 
  the 
  

   leaves 
  habitually 
  near 
  the 
  surface 
  of 
  the 
  water, 
  and 
  so 
  are

  In

  I 
  should 
  probably 
  not 
  have 
  found 
  imagos
