  Mr. 
  K.

  Blair— 
  ^ 
  Bevision 
  of 
  

  

  Pseudopyrochroa, 
  V\c, 
  for 
  P. 
  deplanata, 
  Pic, 
  a 
  group 
  which 
  

   includes 
  tlie 
  bulk 
  of 
  the 
  Oriental 
  species. 
  

  

  And, 
  more 
  recently, 
  Pyj-ochruella, 
  Reitt., 
  for 
  P. 
  pectini- 
  

   cornis, 
  L. 
  

  

  The 
  incorrect 
  assignation, 
  mentioned 
  above, 
  of 
  certain 
  

   species 
  to 
  Dendroides 
  and 
  Schizotus 
  is 
  also 
  a 
  recognition 
  of 
  

   their 
  generic 
  distinction 
  from 
  Pyrochroa. 
  

  

  The 
  present 
  paper 
  is 
  an 
  attempt 
  to 
  coordinate 
  and 
  extend 
  

   tliese 
  efforts, 
  and, 
  though 
  necessaril}^, 
  from 
  lack 
  of 
  know- 
  

   ledge 
  and 
  lack 
  of 
  material, 
  full 
  of 
  defects, 
  it 
  is 
  hoped 
  that 
  

   the 
  very 
  obviousness 
  of 
  these 
  may 
  help 
  to 
  remedy 
  some 
  of 
  

   them 
  and 
  supply 
  the 
  deficiencies. 
  

  

  I 
  must 
  express 
  my 
  deep 
  indebtedness 
  to 
  numerous 
  coleo- 
  

   pterists 
  for 
  the 
  valuable 
  and 
  kindly 
  aid 
  they 
  have 
  rendered 
  

   me, 
  as 
  well 
  by 
  the 
  communication 
  of 
  notes 
  and 
  specimens 
  as 
  

   in 
  allowing 
  me 
  to 
  examine 
  types 
  in 
  their 
  possessioti. 
  My 
  

   thanks 
  are 
  particularly 
  due 
  to 
  Messrs. 
  H. 
  E. 
  Andrewes 
  and 
  

   G, 
  E. 
  Bryant, 
  to 
  M. 
  Pierre 
  Lesne 
  and 
  the 
  authorities 
  of 
  the 
  

   Paris 
  Museum, 
  and, 
  above 
  all, 
  to 
  M. 
  Maurice 
  Pic, 
  who 
  has 
  

   not 
  only 
  been 
  most 
  generous 
  in 
  giving 
  me 
  all 
  information 
  at 
  

   his 
  disposal, 
  but 
  whose 
  hospitality 
  has 
  enalded 
  me 
  to 
  examine 
  

   the 
  whole 
  of 
  his 
  rich 
  collection 
  of 
  this 
  family.
