  Common 
  in 
  the 
  Middle 
  and 
  Southern 
  States. 
  Some 
  of 
  the 
  specimens 
  have 
  the 
  sides 
  of 
  

   the 
  thorax 
  more 
  rounded 
  than 
  others; 
  these 
  are 
  probably 
  females: 
  the 
  branches 
  of 
  the 
  

   antennae 
  do 
  not, 
  however, 
  appear 
  to 
  be 
  shorter 
  than 
  usual 
  in 
  such 
  specimens: 
  the 
  elytra 
  

   in 
  all 
  of 
  them 
  are 
  tolerably 
  strongly 
  nan-owed 
  from 
  the 
  base 
  to 
  the 
  tip, 
  and 
  the 
  stria; 
  on 
  

   the 
  middle 
  of 
  the 
  disc 
  consequently 
  run 
  together, 
  and 
  vanish 
  before 
  reaching 
  the 
  apex. 
  

   The 
  head 
  is 
  subject 
  to 
  abnormal 
  impressions: 
  in 
  one 
  specimen 
  there 
  are 
  three 
  occipital 
  

   grooves: 
  in 
  another, 
  two 
  faint 
  ones 
  just 
  behind 
  the 
  antennal 
  sinus: 
  in 
  a 
  third, 
  there 
  is 
  a 
  

   broad 
  frontal 
  fovea, 
  such 
  as 
  has 
  been 
  already 
  mentioned 
  in 
  some 
  species 
  of 
  Fornax.

   The 
  North 
  American 
  species 
  of 
  this 
  genus 
  is 
  unknown 
  to 
  me: 
  a 
  single 
  specimen 
  was 
  

   obtained 
  in 
  Georgia 
  by 
  my 
  father, 
  who 
  sent 
  it 
  to 
  Count 
  Dejean. 
  On 
  account 
  of 
  the 
  lobes 
  

   of 
  the 
  second, 
  third, 
  and 
  fourth 
  joints 
  of 
  the 
  tarsi 
  being 
  shorter 
  than 
  in 
  the 
  Galbae 
  of 
  the 
  

   eastern 
  continent, 
  Mr. 
  Guerin 
  proposed 
  to 
  form 
  of 
  this 
  species 
  a 
  subgenus 
  Dendrocharis.

  I 
  add 
  a

  Guerin's 
  description:

  A 
  male 
  specimen 
  sent 
  me 
  by 
  Dr. 
  Schaum.* 
  This 
  species 
  has 
  the 
  antenna? 
  subflabellate, 
  

   as 
  in 
  Eucnemis 
  amaenicornis, 
  but 
  as 
  the 
  pectoral 
  grooves 
  are 
  at 
  the 
  side 
  of 
  the 
  presternum, 
  

   it 
  cannot 
  be 
  associated 
  with 
  that 
  species. 
  It 
  differs 
  from 
  all 
  the 
  following 
  species 
  in 
  

   having 
  the 
  marginal 
  line 
  of 
  the 
  thorax 
  double 
  before 
  the 
  middle, 
  and 
  the 
  posterior 
  angles 
  

   more 
  strongly 
  carinate: 
  the 
  pectoral 
  grooves 
  are 
  well 
  defined 
  and 
  broad: 
  the 
  ungues 
  of 
  

   the 
  tarsi 
  are 
  slender.] 
  

  

  'this 
  European 
  species 
  is 
  described 
  in 
  connexion 
  with 
  our 
  native 
  species 
  for 
  the 
  purpose 
  of 
  exhibiting 
  the 
  specific 
  

   characters 
  more 
  clearly; 
  I 
  are. 
  therefore, 
  omitted.
