  clature 
  but, 
  regardless 
  of 
  that 
  aspect 
  of 
  the 
  matter, 
  the 
  validity 
  of 
  

   Leucophaea^

  is

  Recognition 
  features. 
  — 
  The 
  most 
  important 
  features 
  in 
  the 
  recog- 
  

   nition 
  of 
  Leucophaea 
  maderae 
  are 
  : 
  (1) 
  Large 
  size, 
  overall 
  length 
  about 
  

   38 
  to 
  53 
  millimeters; 
  (2) 
  pronotal 
  shape, 
  and 
  general 
  color 
  markings 
  

   as 
  illustrated 
  (pi. 
  2, 
  figs. 
  1, 
  2) 
  ; 
  (3) 
  no 
  strong 
  spines 
  along 
  posterior 
  

   margins 
  of 
  femora 
  except 
  one 
  short 
  apical 
  spine 
  on 
  each 
  hind 
  and 
  

   middle 
  femur; 
  (4) 
  in 
  males 
  the 
  characteristic 
  shape 
  of 
  the 
  specialized 
  

   organ 
  on 
  the 
  dorsal 
  surface 
  of 
  the 
  second 
  abdominal 
  segment 
  and 
  of 
  

   the 
  subgenital 
  plate 
  (fig. 
  10, 
  e, 
  h.). 
  

  

  Relatively 
  few 
  Nearctic 
  roaches 
  are 
  as 
  large 
  as 
  L, 
  maderae., 
  and 
  none 
  

   of 
  them 
  is 
  likely 
  to 
  be 
  confused 
  with 
  it. 
  Blaherus 
  craniifer 
  Burmeister, 
  

   illustrated 
  by 
  Hebard 
  (1917, 
  pi. 
  8, 
  fig. 
  6), 
  is 
  the 
  largest 
  roach 
  in 
  the 
  

   United 
  States, 
  being 
  much 
  larger 
  than 
  maderae. 
  The 
  species 
  of 
  

   Perijylaneta 
  are 
  quite 
  differently 
  marked, 
  and 
  have 
  numerous 
  heavy 
  

   spines 
  on 
  the 
  posterior 
  margins 
  of 
  the 
  femora. 
  Both 
  Eurycotis 
  

   floridana 
  (Walker), 
  of 
  the 
  Southeast, 
  and 
  Hemihldbera 
  tenehricosa 
  

   Rehn 
  and 
  Hebard,^ 
  of 
  the 
  Florida 
  Keys, 
  have 
  short, 
  lobate 
  tegmina 
  

   and 
  wings 
  which 
  are 
  vestigial 
  or 
  lacking. 
  

  

  A 
  relative 
  of 
  L. 
  maderae 
  recently 
  established 
  in 
  Florida 
  is 
  

   Nauphoeta 
  cinerea 
  (Olivier). 
  It 
  superficially 
  resembles 
  maderae.^ 
  

   though 
  it 
  is 
  smaller, 
  its 
  average 
  length 
  being 
  about 
  23 
  millimeters. 
  

   The 
  femora 
  are 
  proportionately 
  stouter 
  and 
  the 
  tegmina 
  scarcely 
  ex- 
  

   tend 
  beyond 
  the 
  apex 
  of 
  the 
  abdomen, 
  while 
  the 
  posterior 
  margin 
  of 
  

   the 
  pronotum 
  is 
  transversely 
  subtruncate, 
  a 
  median 
  projection 
  being 
  

   scarcely 
  evident. 
  Zimmerman 
  (1948, 
  p. 
  94) 
  and 
  Rehn 
  (1945, 
  p. 
  274) 
  

   have 
  given 
  photographs 
  of 
  cinerea. 
  This 
  species 
  is 
  apparently 
  a 
  na- 
  

   tive 
  of 
  East 
  Africa 
  now 
  widely 
  distributed 
  in 
  the 
  Tropics 
  by 
  com- 
  

   merce 
  and 
  often 
  intercepted 
  at 
  United 
  States 
  ports. 
  Its 
  potential 
  

   importance 
  is 
  suggested 
  by 
  Illingworth 
  (1942), 
  who 
  described 
  its 
  oc- 
  

   currence 
  in 
  alarming 
  numbers 
  about 
  the 
  feed 
  room 
  of 
  the 
  poultry 
  

   plant 
  at 
  the 
  University 
  of 
  Hawaii. 
  He 
  also 
  mentioned 
  its 
  occurrence 
  

   in 
  heated 
  buildings 
  in 
  England 
  and 
  Germany, 
  though 
  no 
  records 
  of 
  

   permanent 
  establishment 
  in 
  those 
  countries 
  have 
  come 
  to 
  my 
  attention. 
  

  

  In 
  early 
  December 
  1951 
  material 
  of 
  cinerea 
  was 
  received 
  from 
  Jo- 
  

   seph 
  Gross 
  of 
  Tampa, 
  Fla., 
  who 
  stated 
  that 
  it 
  was 
  widely 
  and 
  thor- 
  

   oughly 
  established 
  about 
  Tampa, 
  especially 
  in 
  feed 
  mills. 
  Later, 
  in 
  

   August 
  1952, 
  Mr. 
  Gross 
  contributed 
  a 
  series 
  of 
  34 
  adults 
  and 
  32 
  nymphs 
  

  

  s 
  IlemiMaiera 
  tenebricosa 
  was 
  described 
  from 
  the 
  West 
  Indies, 
  including 
  Nassau 
  in 
  the 
  

   Bahamas, 
  by 
  Rehn 
  and 
  Hebard 
  (1927, 
  p. 
  271). 
  Caudell 
  (1931) 
  recorded 
  an 
  adult 
  pair 
  

   collected 
  at 
  Key 
  Largo. 
  Fla., 
  by 
  E. 
  A. 
  Popenoe 
  in 
  1896. 
  Caudell's 
  unpublished 
  notes 
  dis- 
  

   close 
  subsequent 
  discussions 
  of 
  this 
  record 
  with 
  Mr. 
  Popenoe's 
  son, 
  who 
  explained 
  that 
  his 
  

   father 
  was 
  collecting 
  insects 
  primarily 
  for 
  Kansas 
  State 
  College 
  during 
  the 
  1896 
  trip 
  and 
  

   that 
  in 
  view 
  of 
  conditions 
  at 
  Key 
  Largo 
  at 
  that 
  time 
  this 
  roach 
  was 
  probably 
  an 
  established 
  

   species 
  rather 
  than 
  an 
  intercepted 
  adventive. 
  A 
  number 
  of 
  roaches 
  are 
  now 
  known 
  to 
  

   be 
  native 
  to 
  the 
  northern 
  Bahamas 
  and 
  extreme 
  tropical 
  Florida, 
  so 
  the 
  occurrence 
  of 
  

   tenehricosa 
  in 
  the 
  Florida 
  Keys 
  Is 
  not 
  illogical.
