  HEMIPTERA 
  

  

  I 
  was 
  struck 
  with 
  the 
  absence 
  of 
  the 
  larger 
  aquatic 
  Hemiptera, 
  such 
  

   asBelostoma, 
  Zaitha, 
  Nepa, 
  etc., 
  from 
  all 
  the 
  waters 
  in 
  

   which 
  I 
  did 
  any 
  collecting 
  about 
  Saranac 
  Inn. 
  I 
  was 
  not 
  looking 
  for 
  

   them 
  ; 
  but, 
  if 
  they 
  had 
  ever 
  got 
  into 
  my 
  net, 
  as 
  they 
  have 
  done 
  unfail- 
  

   ingly 
  in 
  every 
  other 
  locality 
  in 
  which 
  I 
  have 
  ever 
  collected, 
  they 
  could 
  

   not 
  but 
  have 
  been 
  seen. 
  OfRanatra 
  I 
  caught 
  a 
  few 
  specimens 
  in 
  

   the 
  vegetation 
  about 
  the 
  shores 
  of 
  Bone 
  pond. 
  Of 
  terrestrial 
  Hemiptera 
  

   there 
  seemed 
  to 
  be 
  no 
  scarcity.

  These 
  were 
  not 
  uncommon 
  in 
  the 
  damp 
  woods 
  along 
  the 
  road 
  between 
  

   the 
  railroad 
  and 
  Little 
  Green 
  pond. 
  

  

  COLEOPTERA 
  

  

  Though 
  little 
  attention 
  was 
  paid 
  this 
  order, 
  considerable 
  material 
  was 
  

   collected. 
  But 
  two 
  species 
  were 
  reared, 
  however: 
  Galerucella 
  

   n 
  y 
  m 
  p 
  h 
  a 
  e 
  and 
  Donacia 
  emarginata. 
  The 
  latter 
  species 
  

   was 
  associated 
  with 
  D, 
  sub 
  ti 
  lis 
  Kunze 
  and 
  D. 
  pusilla 
  Say; 
  

   and, 
  because 
  of 
  unfamiliarity 
  with 
  the 
  distinctive 
  characters 
  of 
  Donacia 
  

   larvae 
  and 
  pupae, 
  I 
  have 
  been 
  unable 
  to 
  determine 
  as 
  yet 
  whether 
  I 
  have, 
  

   among 
  the 
  numerous 
  larvae 
  collected, 
  those 
  of 
  more 
  species 
  than 
  the 
  one 
  

   that 
  was 
  reared. 
  For 
  the 
  present, 
  I 
  content 
  myself 
  with 
  giving 
  a 
  few 
  

   biologic 
  notes 
  and 
  figures.

   of 
  Donacia 
  emarginata 
  Kirby 
  on 
  Sparganium 
  in 
  several 
  

   stages 
  will 
  doubtless 
  be 
  welcome 
  to 
  entomologists. 
  The 
  material 
  for 
  

   these 
  photographs 
  was 
  obtained 
  while 
  making 
  the 
  second 
  quantitative 
  

   study 
  detailed 
  in 
  part 
  2, 
  and 
  farther 
  oecological 
  information 
  is

   recorded
