  the 
  males 
  of 
  this 
  genus 
  are 
  dimorphic 
  in 
  wing 
  length 
  and 
  that 
  most 
  

   or 
  all 
  the 
  species 
  will 
  be 
  found 
  with 
  short-winged 
  males, 
  though 
  such 
  

   conditions 
  are 
  uncommon 
  in 
  the 
  Mantidoe. 
  SJcinneri 
  was 
  described 
  

   from 
  Arizona 
  but 
  has 
  since 
  been 
  recorded 
  from 
  Texas, 
  New 
  Mexico, 
  

   and 
  California 
  and 
  also 
  occurs 
  in 
  Colorado 
  and 
  Nebraska. 
  It 
  may 
  

   prove 
  to 
  be 
  the 
  brachypterous 
  form 
  of 
  an 
  older 
  species 
  if 
  the 
  males 
  

   of 
  these 
  insects 
  do 
  prove 
  to 
  be 
  dimorphic 
  in 
  wing 
  length. 
  

  

  Since 
  Scudder's 
  catalogue 
  appeared 
  there 
  have 
  been 
  two 
  species 
  of 
  

   the 
  genus 
  Stagmomantis 
  described, 
  S. 
  gracilipes 
  Eehn, 
  from 
  Arizona, 
  

   and 
  S. 
  califomica 
  Rehn 
  and 
  Hebard 
  from 
  California. 
  The 
  former 
  I 
  

   do 
  not 
  know, 
  the 
  type, 
  a 
  single 
  male, 
  being 
  in 
  the 
  Snow 
  collection 
  in 
  

   Kansas. 
  It 
  seems 
  closely 
  allied 
  to 
  limbata. 
  Of 
  what 
  I 
  consider 
  as 
  

   S. 
  califomica 
  I 
  have 
  one 
  male 
  from 
  Oil 
  Center, 
  California, 
  one 
  pair

  from 
  Golden 
  Roads, 
  Arizona, 
  one 
  female 
  from 
  Rhyohte, 
  Nevada, 
  one 
  

   male 
  from 
  Las 
  Cruces, 
  New 
  Mexico, 
  and 
  one 
  female 
  from 
  El 
  Paso, 
  

   Texas. 
  

  

  Probably 
  all 
  of 
  the 
  species 
  of 
  this 
  genus 
  come 
  in 
  both 
  green 
  and 
  

   brown 
  colored 
  forms. 
  The 
  typical 
  color 
  of 
  the 
  common 
  eastern 
  

   species, 
  S. 
  Carolina, 
  is 
  brown, 
  the 
  green 
  form 
  bearing 
  the 
  name 
  

   irrorata 
  of 
  Linnaeus. 
  

  

  The 
  three

  fauna
