  THE 
  BEETLE 
  FAMILY 
  PSEUDOMORPHIDAE 
  NOTMAN 
  13 
  

  

  truncate 
  and 
  about 
  equally 
  prominent 
  at 
  either 
  end. 
  This 
  series 
  

   includes 
  angustata, 
  Horn 
  and 
  the 
  related 
  species, 
  rhaniplaini 
  Not- 
  

   man, 
  schwarzi 
  Notman, 
  also 
  the 
  species 
  lacordairei 
  Depan, 
  arrowi 
  

   Notman, 
  behrensi 
  Horn, 
  castanea 
  Casey, 
  vindicata 
  Notman, 
  and 
  

   habbardi 
  Notman. 
  Another 
  interesting 
  character 
  which 
  it 
  was 
  

   not 
  found 
  necessary 
  to 
  use 
  in 
  the 
  synoptic 
  analysis 
  is 
  found 
  in 
  the 
  

   margination 
  of 
  the 
  base 
  of 
  the 
  thorax. 
  In 
  the 
  species 
  pUatei 
  

   Chaudoir, 
  tenebroides 
  Notman, 
  alutacea 
  Notman, 
  vandykei 
  Not- 
  

   man, 
  consanguinea 
  Notman, 
  the 
  thorax 
  is 
  finely 
  margined 
  medially 
  

   at 
  base. 
  This 
  margin 
  is 
  beaded 
  with 
  the 
  setigerous 
  punctures 
  which 
  

   are 
  found 
  in 
  a 
  series 
  around 
  the 
  lateral 
  edges 
  of 
  both 
  thorax 
  and 
  

   elytra. 
  The 
  oth%r 
  species 
  are 
  without 
  this 
  margin 
  with 
  the 
  excep- 
  

   tion 
  of 
  confusa 
  Notman. 
  In 
  the 
  type 
  of 
  the 
  latter 
  the 
  base 
  of 
  the 
  

   thorax 
  is 
  finely 
  and 
  completely 
  margined. 
  The 
  margin 
  is 
  not, 
  how- 
  

   ever, 
  beaded 
  with 
  the 
  setigerous 
  punctures. 
  In 
  the 
  angustata 
  .series 
  

   the 
  head 
  is 
  distinctly 
  less 
  transverse 
  than 
  in 
  the 
  other 
  species. 
  

   The 
  elytral 
  punctuation 
  in 
  confusa 
  Notman, 
  and 
  hubbardi 
  Not- 
  

   man, 
  is 
  simple, 
  consisting 
  of 
  rows 
  of 
  coarse 
  punctures 
  only. 
  In 
  

   the 
  others 
  the 
  punctures 
  are 
  both 
  coarse 
  and 
  fine, 
  the 
  coarse 
  in 
  

   rows 
  but 
  the 
  fine 
  sometimes 
  without 
  distinct 
  arrangement. 
  The 
  

   anal 
  setigerous 
  punctures 
  exhibit 
  a 
  large 
  amount 
  of 
  variability. 
  

   The 
  number 
  often 
  differs 
  on 
  either 
  side 
  in 
  individuals. 
  Some 
  have 
  

   but 
  two 
  on 
  either 
  side; 
  others 
  as 
  many 
  as 
  five. 
  The 
  latter 
  was 
  

   found 
  to 
  be 
  the 
  number 
  in 
  a 
  male 
  excru.cians 
  Kirby 
  and 
  a 
  female 
  

   behrensi 
  Horn. 
  There 
  appears 
  to 
  be 
  no 
  difference 
  in 
  the 
  number 
  

   between 
  the 
  sexes. 
  The 
  number 
  averages 
  lowest 
  in 
  angustata 
  

   Horn, 
  and 
  its 
  relatives. 
  

  

  The 
  proportions 
  of 
  the 
  thorax 
  are 
  often 
  deceptive 
  and 
  therefore 
  

   more 
  or 
  less 
  unreliable 
  on 
  account 
  of 
  a 
  tendency 
  to 
  distortion 
  through 
  

   warping 
  of 
  the 
  integuments. 
  

  

  E. 
  A. 
  Schwarz, 
  who 
  has 
  made 
  a 
  study 
  of 
  the 
  genus, 
  kindly 
  turned 
  

   over 
  his 
  notes 
  to 
  the 
  author. 
  Characters 
  of 
  ^systematic 
  value, 
  the 
  

   transverse 
  row 
  of 
  coarse 
  punctures 
  on 
  the 
  head 
  and 
  the 
  variation 
  in 
  

   the 
  width 
  of 
  the 
  pubescent 
  spots 
  on 
  the 
  third 
  and 
  fourth 
  abdominal 
  

   segments 
  of 
  the 
  male, 
  are 
  indicated 
  by 
  him. 
  The 
  former 
  character 
  

   is 
  made 
  use 
  of 
  in 
  the 
  synopsis 
  of 
  the 
  species. 
  The 
  male 
  character 
  

   will 
  distinguish 
  schwarzi 
  Notman 
  and 
  champlaini 
  Notman 
  from 
  

   angustata 
  Horn, 
  the 
  spots 
  being 
  narrower 
  in 
  the 
  former. 
  

  

  Dr. 
  Schwarz 
  writes 
  that 
  the 
  Pseud 
  omorphas 
  are 
  numerous 
  in 
  their 
  

   habitat, 
  but 
  are 
  difficult 
  to 
  capture. 
  They 
  live 
  in 
  dead 
  leaves 
  and 
  

   move 
  with 
  great 
  agility, 
  assisted 
  by 
  the 
  numerous 
  setae 
  with 
  which 
  

   they 
  are 
  provided. 
  They 
  are 
  easy 
  to 
  capture 
  on 
  cloth 
  when 
  attracted 
  

   to 
  light. 
  A 
  large 
  series 
  was 
  collected 
  by 
  Dr. 
  E. 
  E. 
  Lutz 
  in 
  Arizona 
  

   by 
  the 
  latter 
  method.
