﻿A 
  SYNOPTIC 
  REVIEW 
  OF 
  THE 
  BEETLES 
  OF 
  THE 
  TRIBE 
  

   OSORIINI 
  FROM 
  THE 
  WESTERN 
  HEMISPHERE.

  Brooklyn, 
  New 
  York. 
  

  

  The 
  Osoriini 
  of 
  Erichson 
  and 
  the 
  Osoriides 
  of 
  Lacordaire 
  both 
  

   contain 
  but 
  two 
  genera, 
  Holotrochus 
  and 
  Osorius 
  distinguished 
  by 
  

   the 
  presence 
  or 
  absence 
  of 
  spines 
  on 
  the 
  outer 
  edges 
  of 
  the 
  tibiae. 
  

   Since 
  the 
  publication 
  of 
  the 
  Genera 
  des 
  Coleopteres 
  (1854) 
  many 
  

   new 
  genera 
  and 
  species 
  have 
  been 
  added 
  to 
  the 
  group. 
  In 
  Part 
  29 
  

   of 
  the 
  Coleopterorum 
  Catalogus 
  of 
  Junk 
  and 
  Schenkling 
  published 
  

   in 
  1911 
  the 
  genera 
  number 
  11. 
  At 
  the 
  beginning 
  of 
  1923 
  the 
  genera 
  

   number 
  13 
  and 
  121 
  described 
  species 
  are 
  referred 
  to 
  the 
  genus 
  

   Osorius 
  — 
  65 
  from 
  the 
  Eastern 
  and 
  56 
  from 
  the 
  Western 
  Hemi- 
  

   sphere. 
  The 
  author 
  has 
  felt 
  obliged 
  to 
  add 
  to 
  this 
  number. 
  The 
  

   present 
  paper 
  contains 
  descriptions 
  of 
  2 
  new 
  genera 
  and 
  17 
  new 
  

   species, 
  15 
  of 
  the 
  latter 
  are 
  referred 
  to 
  Osorius. 
  

  

  In 
  spite 
  of 
  the 
  large 
  number 
  of 
  species 
  described, 
  little 
  or 
  nothing 
  

   has 
  been 
  published 
  concerning 
  the 
  systematics 
  of 
  that 
  genus 
  which 
  

   makes 
  the 
  task 
  of 
  consulting 
  the 
  scattered 
  descriptions 
  a 
  laborious 
  

   one. 
  In 
  the 
  Biologia 
  Centrali-Americana, 
  1 
  Sharp 
  separates 
  two 
  

   groups, 
  one 
  of 
  7 
  and 
  the 
  other 
  of 
  8 
  species, 
  by 
  the 
  form 
  of 
  the 
  

   thoracic 
  margin. 
  Fauvel 
  gives 
  a 
  table 
  for 
  the 
  separation 
  of 
  5 
  

   species 
  described 
  from 
  New 
  Guinea, 
  based 
  on 
  the 
  sculpture 
  of 
  the 
  

   head.

  It 
  is 
  hoped 
  that 
  the 
  present 
  review 
  may 
  suggest 
  lines 
  for 
  future 
  

   investigations 
  and 
  assist 
  those 
  wishing 
  to 
  consult 
  the 
  published 
  

   descriptions. 
  

  

  It 
  is 
  well 
  to 
  call 
  the 
  reader's 
  attention 
  to 
  the 
  fact 
  that 
  the 
  original 
  

   tribe 
  Osoriini 
  containing 
  Holotrochus 
  and 
  Osorius 
  included 
  only 
  

   species 
  having 
  the 
  tarsi 
  5-jointed,' 
  whereas 
  the 
  present 
  tribe 
  con- 
  

   tains 
  genera 
  in 
  which 
  the 
  tarsi 
  are 
  3- 
  and 
  4-jointed, 
  bringing 
  it 
  into 
  

   closer 
  relationship 
  with 
  the 
  Oxytelini. 
  It 
  may 
  eventually 
  prove 
  

   advisable 
  to 
  divide 
  the 
  tribe 
  on 
  the 
  tarsal 
  structure. 
  

  

  The 
  material 
  for 
  this 
  study 
  consists 
  of 
  123 
  specimens 
  from

   collection 
  of

  United
