﻿AQUATIC 
  INSECTS 
  IN 
  THE 
  ADIRONDACKS 
  393. 
  

  

  Special 
  collections 
  were 
  made 
  of 
  aquatic 
  insect 
  species 
  hitherto 
  insuf- 
  

   ficiently 
  known, 
  of 
  which 
  not 
  a 
  few 
  species 
  known 
  only 
  from 
  a 
  few 
  poor 
  

   specimens 
  appeared 
  at 
  Saranac 
  Inn 
  in 
  great 
  numbers^ 
  and 
  we 
  took 
  oc- 
  

   casion 
  to 
  gather 
  good 
  series 
  of 
  specimens 
  of 
  such, 
  and 
  also 
  of 
  a 
  few 
  

   new 
  species 
  which 
  were 
  no 
  less 
  abundant. 
  

  

  The 
  most 
  valuable 
  collections 
  were 
  those 
  of 
  life 
  history 
  material. 
  All. 
  

   that 
  is 
  described 
  in 
  part 
  3 
  of 
  this 
  report 
  as 
  coming 
  from 
  Saranac 
  Inn 
  has 
  

   been 
  added 
  to 
  the 
  state 
  museum; 
  and 
  so 
  important 
  is 
  tills 
  material 
  that 
  

   future 
  monographers 
  in 
  several 
  groups 
  will 
  find 
  it 
  very 
  desirable 
  to 
  con- 
  

   sult 
  the 
  collections 
  at 
  Albany. 
  

  

  Aquatic

  Adirondacks. 
  All 
  that 
  has 
  been 
  

   written 
  on 
  this 
  subject 
  is 
  comprised 
  in 
  a 
  few 
  short 
  paragraphs 
  in 
  two 
  

   papers 
  by 
  Dr 
  Lintner/ 
  in 
  a 
  few 
  isolated 
  desciiptions 
  of 
  Adirondack 
  

   species, 
  like 
  that 
  ofSimulium 
  pictipes, 
  from 
  Ausable 
  river, 
  by 
  Dr 
  

   Hagen,^ 
  in 
  a 
  record 
  by 
  Dr 
  Calvert^ 
  of 
  a 
  few 
  dragon 
  flies 
  collected 
  at 
  

   Lake 
  St 
  Regis 
  by 
  J. 
  Percy 
  Moore 
  in 
  1890, 
  and 
  at 
  Keesville 
  by 
  W. 
  

   Sheraton 
  in 
  1894, 
  and 
  in 
  rare 
  locality 
  references 
  in 
  other 
  lists. 
  The' 
  

   Adirondacks 
  are 
  not 
  less 
  interesting 
  entomologically 
  than 
  the 
  White 
  

   mountains, 
  which 
  have 
  been 
  the 
  resort 
  of 
  New 
  England 
  entomologists 
  

   for 
  half 
  a 
  century. 
  

  

  The 
  following 
  lists, 
  while 
  not 
  even 
  pretending 
  an 
  approximation 
  to 
  

   completeness 
  (excepting, 
  perhaps, 
  the 
  suborder 
  Anisoptera 
  of 
  dragon 
  

   flies) 
  add 
  a 
  considerable 
  number 
  of 
  species, 
  not 
  hitherto 
  known 
  to 
  occur 
  

   within 
  our 
  fauna; 
  and 
  also, 
  a 
  small 
  number 
  of 
  interesting 
  new 
  species. 
  

   Of 
  these 
  I 
  have 
  described 
  three 
  species 
  and 
  a 
  variety 
  under 
  the 
  following 
  

   names: 
  Leuctra 
  tenella; 
  Sisyra 
  umbrata; 
  Climacia 
  

   dictyona; 
  Gomphus 
  descriptus 
  var 
  borealis. 
  

  

  I 
  have 
  also 
  described 
  the 
  male 
  of 
  the 
  interesting 
  pygmy 
  May 
  fly, 
  

   Baetis 
  pygmaea 
  Hagen, 
  hitherto 
  known 
  from 
  a 
  fragment 
  of 
  

   a 
  single 
  female 
  specimen, 
  and 
  the 
  female 
  of 
  the 
  beautiful 
  dragon 
  fly,. 
  

   Leucorhinia 
  glacialis 
  Hagen 
  (pi. 
  10). 
  

  

  Mr 
  D. 
  W. 
  Coquillet 
  has 
  described 
  at 
  my 
  request 
  two 
  new 
  genera 
  and 
  

   species 
  of 
  Diptera 
  (see 
  p. 
  585 
  and 
  p. 
  586) 
  ; 
  and 
  W. 
  H. 
  Ashmead 
  has 
  

   described 
  five 
  new 
  species 
  of 
  parasitic 
  Hymenoptera 
  {see 
  p. 
  586) 
  and 
  

   Mr 
  A. 
  D. 
  MacGillivray, 
  two 
  new 
  species 
  of 
  sawflies 
  {see 
  p. 
  585) 
  . 
  

  

  As 
  the 
  region 
  about 
  Saranac 
  Inn 
  differs 
  considerably 
  from 
  most 
  locali- 
  

   ties 
  in 
  the 
  Adirondacks, 
  as 
  stated 
  above, 
  its 
  insect 
  fauna 
  will 
  doubtless
