  ville, 
  Tex., 
  and 
  in 
  the 
  East 
  apparently 
  merging 
  with 
  typical 
  H. 
  agita- 
  

   tor 
  in 
  central 
  Georgia 
  and 
  along 
  tlie 
  "fall 
  line" 
  in 
  North 
  Carolina. 
  H. 
  

   hrevipennis 
  inhabits 
  Florida, 
  Georgia, 
  and 
  Louisiana, 
  and 
  doubtless 
  

   other 
  southeastern 
  States. 
  It 
  may 
  be 
  that 
  any 
  of 
  the 
  crickets 
  men- 
  

   tioned 
  above 
  are 
  satisfactory 
  hosts 
  of 
  Rhopalosoma. 
  In 
  southeastern 
  

   Pennsylvania 
  adults 
  of 
  both 
  Orocharis 
  and 
  Hapithus 
  begin 
  to 
  appear 
  

   by 
  early 
  August, 
  and 
  in 
  all 
  of 
  the 
  more 
  northern 
  States 
  the 
  crickets 
  

   pass 
  the 
  winter 
  as 
  eggs, 
  and 
  adults 
  persist 
  until 
  frost 
  time 
  in 
  the 
  fall. 
  

   Blatchley 
  (1920) 
  reported 
  finding 
  hibernating 
  adults 
  of 
  E. 
  agitator 
  

   in 
  Florida 
  and 
  suggested 
  that 
  they 
  represented 
  a 
  fall 
  generation. 
  The 
  

   subfamily 
  Eneopterinae, 
  to 
  which 
  Eapithus 
  and 
  Orocharis 
  belong, 
  is 
  

   primarily 
  tropical, 
  and 
  various 
  genera 
  are 
  well 
  represented 
  in 
  the 
  

   Neotropical 
  Region, 
  from 
  which 
  Brues 
  (1943) 
  has 
  recognized 
  four 
  

   species 
  of 
  Rhopalosoma.
