  The 
  present 
  paper 
  is 
  based 
  chiefly 
  on 
  specimens 
  in 
  the 
  collection 
  

   of 
  the 
  United 
  States 
  National 
  Museum. 
  We 
  have, 
  however, 
  had 
  the 
  

   great 
  advantage 
  of 
  a 
  loan 
  of 
  material, 
  including 
  types, 
  from 
  the 
  

   Zoological 
  Museum 
  at 
  Helsingfors, 
  Finland 
  ; 
  for 
  this 
  we 
  are 
  greatly 
  

   indebted 
  to 
  Dr. 
  Richard 
  Frey 
  and 
  to 
  Dr. 
  E. 
  Bergroth. 
  H. 
  G. 
  Barber 
  

   also 
  has 
  kindly 
  loaned 
  a 
  considerable 
  number 
  of 
  specimens 
  of 
  the 
  

   genus 
  Geratocombus. 
  This 
  aid 
  has 
  enabled 
  us 
  to 
  make 
  the 
  present 
  

   paper 
  practically 
  a 
  revision 
  of 
  the 
  known 
  American 
  species. 
  

  

  We 
  adopt 
  the 
  family 
  name 
  Cryptostemmatidae 
  based 
  on 
  that 
  of 
  the 
  

   oldest 
  genus 
  ; 
  this 
  course 
  should 
  satisfy 
  also 
  adherents 
  of 
  the 
  so-called 
  

   type-genus 
  method 
  of 
  selecting 
  family 
  names 
  as 
  Cryptostemma 
  pre- 
  

   occupies 
  Dipsocoris 
  upon 
  which 
  the 
  supposed 
  oldest 
  family 
  name 
  for 
  

   the 
  group 
  was 
  based. 
  At 
  least 
  two 
  other 
  names 
  also 
  have 
  been 
  ap- 
  

   plied 
  to 
  the 
  family. 
  

  

  Reuter 
  used 
  the 
  name 
  Ceratocombidae 
  in 
  his 
  monograph 
  of 
  1891 
  

   (see 
  bibliography) 
  and 
  recognized 
  two 
  subfamilies. 
  This 
  latter 
  

   policy 
  we 
  follow, 
  though 
  meanwhile 
  these 
  groups 
  have 
  been 
  ranked 
  as 
  

   families 
  by 
  various 
  authors, 
  and 
  Reuter, 
  treating 
  them 
  so 
  in 
  1910, 
  1 
  

   made 
  the 
  assemblage 
  one 
  of 
  the 
  primary 
  divisions 
  in 
  his 
  system 
  of 
  

   the 
  Heteroptera. 
  

  

  The 
  definition 
  of 
  this 
  series 
  which 
  he 
  called 
  Trichotelocera 
  in 
  no 
  

   way 
  distinguishes 
  these 
  insects 
  from 
  certain 
  Anthocoridae 
  and 
  

   Cimicidae. 
  The 
  more 
  distinctive 
  characters 
  are 
  not 
  mentioned 
  at 
  all 
  

   and 
  the 
  whole 
  effort 
  impresses 
  us 
  as 
  very 
  weak 
  considering 
  the 
  high 
  

   taxonomic 
  rank 
  given 
  the 
  assemblage. 
  The 
  Cryptostemmatinae 
  agree 
  

   in 
  many 
  particulars 
  with 
  some 
  Anthocoridae 
  2 
  (Lyctocorinae), 
  as 
  in 
  

   number 
  of 
  segments 
  of 
  tarsi, 
  beak, 
  and 
  antennae, 
  and 
  in 
  the 
  slender- 
  

   ness 
  and 
  pilosity 
  of 
  the 
  apical 
  two 
  segments 
  of 
  latter, 
  possession 
  of 
  

   ocelli, 
  definite 
  chaetotaxy 
  of 
  head 
  and 
  pronotum, 
  bristly 
  tibiae, 
  and
