  unusually 
  free 
  from 
  each 
  other, 
  the 
  two 
  sclerites 
  together 
  

   forming 
  a

  Much

  mesopleurum, 
  with 
  the 
  coxa 
  

   pointed 
  at 
  the 
  lower 
  and 
  posterior 
  end; 
  both 
  the 
  meso- 
  and 
  metapleurites 
  

   are 
  more 
  oblique 
  than 
  the 
  propleurites, 
  while 
  the 
  meta- 
  are 
  fully 
  as 
  large 
  

   as 
  the

  Termopsis. 
  (Fig.

  The 
  presternum 
  is 
  triangular, 
  about 
  as 
  long 
  as 
  

   broad. 
  

  

  The 
  mesosternum 
  is 
  about 
  three 
  times 
  as 
  large 
  as 
  the 
  prosternum, 
  and 
  

   also 
  equilaterally 
  triangular, 
  with 
  the 
  posterior 
  ai)ex

  Termes 
  flavipes, 
  (Figs. 
  7-9.) 
  The 
  prosternum 
  is 
  rudimentary, 
  consist- 
  

   ing 
  of 
  four 
  sclerites; 
  two 
  large 
  ones 
  next 
  to 
  the 
  episternum 
  in 
  front, 
  and 
  

   two 
  minute 
  triangular 
  ones 
  behind. 
  The 
  meso- 
  and 
  metasterna 
  are 
  

   entire, 
  broadly 
  triangular, 
  and 
  rather 
  large, 
  with 
  a 
  pair 
  of 
  accessory 
  

   sclerites 
  in 
  front 
  of 
  the 
  coxae. 
  The 
  coxae 
  seen 
  from 
  beneath 
  are 
  divided 
  

   by 
  a 
  deeply-impressed 
  longitudinal 
  line.

   oval-oblong; 
  ten
