  BREVIPENNIS 
  (Say). 
  

  

  In 
  general 
  color 
  this 
  subspecies 
  varies 
  from 
  rubiginous 
  to 
  fuscous 
  

   with 
  the 
  pale 
  leg 
  markings 
  distinct; 
  nymphs 
  and 
  teneral 
  specimens 
  

   are 
  paler, 
  mature 
  specimens 
  redder 
  or 
  darker.

  Length,

  Many 
  specimens 
  have 
  been 
  examined 
  from 
  a 
  range 
  with 
  the 
  fol- 
  

   lowing 
  States 
  as 
  its 
  extremes 
  : 
  Massachusetts, 
  Missouri, 
  Florida, 
  and 
  

   Texas. 
  The 
  species 
  has 
  been 
  recorded 
  also 
  from 
  Iowa. 
  

  

  The 
  eggs 
  (fig. 
  125) 
  of 
  this 
  species 
  are 
  about 
  2 
  millimeters 
  in 
  

   length, 
  long-elliptical 
  in 
  outline, 
  the 
  opercle 
  with 
  a 
  large 
  central, 
  

   truncately 
  conical 
  tubercle, 
  the 
  periphery 
  of 
  which 
  is 
  more 
  or 
  less 
  

   eroded 
  at 
  the 
  base; 
  the 
  main 
  body 
  of 
  the 
  egg 
  is 
  black 
  in 
  ground 
  color, 
  

   somewhat 
  compressed 
  and 
  with 
  longitudinal 
  rows 
  of 
  membranous, 
  

   saw-tooth-shaped 
  exfoliations, 
  the 
  bases 
  of 
  which 
  are 
  almost 
  con- 
  

   tinuous; 
  these 
  lines 
  of 
  projections 
  are 
  arranged 
  more 
  or 
  less 
  in 
  con- 
  

   centric 
  ellipses 
  (if 
  we 
  may 
  use 
  the 
  expression) 
  on 
  the 
  flat 
  sides 
  of 
  the 
  

   egg. 
  Specimens 
  examined 
  were 
  laid 
  by 
  a 
  female 
  captured 
  on 
  Plum- 
  

   mer 
  Island, 
  Md., 
  October 
  6, 
  1912. 
  This 
  individual 
  laid 
  about 
  20 
  

   eggs

   as 
  follows 
  : 
  A 
  slender 
  vitta 
  from

  of 
  antenna 
  along 
  side 
  of 
  head, 
  

   interrupted 
  at 
  eye 
  ; 
  two 
  more 
  or 
  less 
  interrupted 
  vittae 
  along

   all 
  divisions 
  of 
  thorax; 
  a 
  slender 
  line 
  along 
  outside 
  of 
  each 
  front 
  

   coxa 
  and 
  trochanter; 
  front 
  femur 
  with 
  a

   knee;

  2 
  series 
  of 
  markings, 
  each 
  con- 
  

   sisting 
  of 
  a 
  dot 
  and 
  2 
  dashes; 
  spiracles 
  black. 
  The 
  posterior 
  lol>e 
  of

  more

  EMESAYA 
  BREVIPENNIS 
  AUSTRALIS, 
  new 
  subspecies. 
  

  

  From 
  the 
  Gulf 
  States 
  southward 
  to 
  Panama 
  occurs 
  what 
  seems 
  to 
  

   be 
  a 
  geographical 
  race 
  characterized 
  by 
  a 
  strong 
  tendency, 
  which 
  is 
  

   almost 
  universal 
  among 
  the 
  males, 
  to 
  lack 
  all 
  pale 
  leg 
  markings 
  

   except 
  at 
  knees. 
  We 
  have 
  not 
  been 
  able 
  to 
  correlate 
  this 
  character
