  adoption, 
  and 
  the 
  proposal 
  to 
  break 
  up 
  the 
  great 
  group 
  of 
  Brachelytra, 
  and 
  to 
  unite 
  the 
  

   Pselaphidae 
  and 
  Scydmenidae 
  into 
  one 
  group, 
  appears 
  to 
  me 
  quite 
  unnatural. 
  Several 
  

   of 
  the 
  species 
  are 
  recorded 
  as 
  having 
  been 
  taken 
  in 
  company 
  with 
  small 
  ants, 
  but 
  

   others 
  under 
  the 
  bark 
  of 
  trees 
  ; 
  and 
  of 
  the 
  species 
  of 
  Batrisus, 
  it 
  is 
  remarked 
  that 
  in 
  

   the 
  Northern 
  States 
  scarcely 
  an 
  individual 
  is 
  seen 
  apart 
  from 
  a 
  colony 
  of 
  ants, 
  but 
  in 
  

   the 
  South 
  they 
  are 
  frequently 
  found 
  under 
  the 
  bark 
  of 
  trees, 
  where 
  no 
  ants 
  are 
  to 
  be 
  

   found. 
  Several 
  new 
  genera 
  are 
  proposed, 
  one 
  of 
  which 
  comprises 
  a 
  blind 
  species.

  con- 
  

   generous

  Languria,
