   Dr

  begins 
  his 
  description 
  of 
  H

  as 
  follows 
  : 
  

   ''H.

  Eich. 
  Berl. 
  Ent.

   1868, 
  147]." 
  Also 
  Leconte, 
  in 
  the 
  same 
  paper 
  \see 
  p. 
  169, 
  173] 
  

   lefers 
  to 
  pages 
  147 
  and 
  149 
  of 
  Eichhoff's 
  article 
  just 
  mentioned. 
  

   There 
  is 
  therefore 
  no 
  question 
  but 
  that 
  both 
  Dr 
  Zimmerman 
  and 
  

   Dr 
  Leconte 
  had 
  Dr 
  Eichhoff's 
  pages 
  146 
  and 
  147 
  before 
  them 
  

   when 
  their 
  descriptions 
  of 
  H. 
  opaculus 
  and 
  H 
  . 
  scabri- 
  

   pennis 
  were 
  written. 
  

  

  In 
  regard 
  to 
  the 
  use 
  of 
  the 
  names 
  Ips, 
  Tomicus, 
  and 
  Hylastes, 
  

   perhaps 
  a 
  few 
  words 
  will 
  be 
  pardoned. 
  The 
  genus 
  Ips 
  was 
  erected 
  

   in 
  1775 
  by 
  De 
  Geer, 
  Dermestes 
  typographus 
  Linne 
  

   being 
  the 
  first 
  species 
  described. 
  All 
  the 
  other 
  species 
  included 
  by 
  

   De 
  Geer 
  in 
  the 
  genus 
  Ips 
  have 
  since 
  been 
  removed 
  to 
  other 
  genera, 
  

   therefore 
  leaving 
  typographus 
  as 
  type. 
  

  

  In 
  1802 
  Latreille 
  described 
  the 
  genus 
  Tomicus, 
  including 
  the 
  

   single 
  species, 
  Hylesinus 
  piniperda 
  Fabr., 
  which 
  would 
  

   therefore 
  be 
  the 
  type. 
  

  

  In 
  1807 
  Latreille 
  referred 
  Dermestes 
  typ"o 
  graph 
  us 
  

   Linne 
  to 
  the 
  genus 
  Tomicus, 
  and 
  gave 
  a 
  description 
  of 
  the 
  genus. 
  

  

  In 
  1836 
  Erichson 
  erected 
  the 
  genus 
  Hylastes 
  with 
  Bostrichus 
  

   ater 
  (=rHylesinus 
  piniperd'a 
  Fabr.) 
  as 
  the 
  type. 
  

  

  Until 
  recently 
  Ips 
  De 
  Geer, 
  1775, 
  seems 
  to 
  have 
  been 
  disregarded, 
  

   and 
  the 
  name 
  Ips 
  has 
  been 
  applied 
  to 
  a 
  genus 
  of 
  beetles 
  of 
  the 
  

   family 
  Nitidulidae. 
  Tomicus 
  Latr., 
  1802, 
  has 
  also 
  been 
  disre- 
  

   garded. 
  Tomicus 
  Latr., 
  1807, 
  has 
  been 
  used 
  for 
  the 
  allies 
  of 
  

   typographus 
  and 
  Hylastes 
  Er., 
  1836, 
  for 
  the 
  allies 
  of 
  ater. 
  

   Ips 
  De 
  Geer, 
  1775, 
  has 
  therefore 
  priority 
  over 
  Tomicus 
  Latr., 
  1807, 
  

   and 
  Tomicus 
  Latr., 
  1802, 
  has 
  priority 
  over 
  Hylastes 
  Er., 
  1836. 
  

  

  The 
  name 
  Ips 
  Fabricius, 
  of 
  the 
  family 
  Nitidulidae, 
  dates 
  from 
  

   the 
  year 
  1776 
  [Fabricius, 
  Gen. 
  Ins. 
  p. 
  23]. 
  

  

  If 
  the 
  above 
  synonymy 
  is 
  correct, 
  and 
  I 
  believe 
  it 
  to 
  be, 
  it 
  is 
  

   better 
  to 
  adopt 
  it 
  at 
  once, 
  even 
  at 
  the 
  risk 
  of 
  temporary 
  confusion. 
  

  

  Following 
  Bedel 
  [Faun. 
  Col. 
  Bassin 
  Seine, 
  Rhyn, 
  1888], 
  Hy- 
  

   lastes 
  is 
  dropped 
  in 
  this 
  paper 
  and 
  the 
  terms 
  Ips 
  and 
  Tomicus 
  are 
  

   used 
  as 
  indicated 
  above. 
  

  

  Geoffroy's 
  name 
  Scolytus 
  dates 
  from 
  1762, 
  and 
  therefore 
  can 
  

   not 
  be 
  accepted. 
  In 
  1776, 
  O. 
  F. 
  Muller 
  [Zool. 
  Dan. 
  Prodr. 
  57], 
  

   described 
  Scolytus 
  punctatus 
  which 
  is 
  certainly 
  not 
  a 
  

   scolytid 
  : 
  " 
  Niger, 
  thorace 
  fossulato,
