  anterior 
  or 
  scutal 
  and 
  a 
  posterior 
  or 
  scutellar 
  region. 
  Each 
  side 
  of 
  the 
  

   scutal 
  region 
  is 
  swollen 
  in 
  front, 
  but 
  the 
  scutellum 
  is 
  not 
  indicated 
  by 
  

   sutures. 
  Posteriorly 
  the 
  scutellar 
  region 
  spreads 
  out 
  laterally. 
  The 
  

   wings 
  on 
  both 
  segments 
  are 
  only 
  attached 
  by 
  feeble, 
  local, 
  restricted 
  

   areas 
  to 
  the 
  front 
  part 
  of 
  the 
  scutum. 
  

  

  In 
  Termes 
  flavipes 
  (PI. 
  XLII, 
  figs. 
  1-3) 
  there 
  are 
  important 
  differences 
  

   from 
  Termopsis. 
  

  

  The 
  pronotum 
  is 
  one-half 
  as 
  long 
  as 
  the 
  head, 
  well 
  rounded 
  behind, 
  

   and 
  one-fourth 
  shorter 
  than 
  broad*. 
  

  

  In 
  the 
  mesonotum 
  the 
  scutum 
  and 
  scutellum 
  are 
  differentiated 
  j 
  the 
  

   scutum 
  is 
  broad 
  and 
  short, 
  one-half 
  as 
  long 
  as 
  broad, 
  and 
  rounded 
  be- 
  

   hind. 
  The 
  scutellum 
  is 
  quite 
  free 
  from 
  it, 
  and 
  is 
  larger 
  than 
  the 
  scutum, 
  

   being 
  longer, 
  with 
  the 
  sides 
  prolonged 
  toward 
  the 
  posterior 
  insertion 
  of 
  

   the 
  wings. 
  

  

  In 
  the 
  metanotum 
  (Fig. 
  3) 
  the 
  scutum 
  is 
  very 
  broad 
  and 
  short, 
  shorter 
  

   than 
  the 
  mesoscutum, 
  and 
  only 
  two-thirds 
  as 
  long 
  as 
  the 
  metascutel- 
  

   lum; 
  the 
  latter 
  is 
  large 
  and 
  broad, 
  being 
  a 
  little 
  shorter 
  than 
  broad. 
  

   No 
  prse- 
  or 
  postscutellum 
  in 
  either 
  segment. 
  

  

  The 
  meso- 
  and 
  metanotum 
  are 
  considerably 
  narrower 
  than 
  the 
  thorax 
  

   itself, 
  and 
  are 
  margined 
  with 
  membrane, 
  the 
  insertion 
  of 
  the 
  wings 
  

   being 
  tergal 
  and 
  very 
  weak. 
  

  

  Pleurum, 
  

  

  Fropleurum 
  {Termopsis 
  angusticollis). 
  (Fig. 
  4.) 
  The 
  sides 
  of 
  the 
  pro- 
  

   thorax 
  are 
  much 
  flattened, 
  as 
  if 
  (seen 
  from 
  above) 
  the 
  body 
  had 
  been 
  

   squeezed 
  and 
  the 
  flanks 
  pressed 
  out, 
  so 
  that 
  they 
  present 
  a 
  rather 
  wide 
  

   lateral 
  area 
  on 
  each 
  side 
  of 
  the 
  tergites. 
  The 
  episternum 
  forms 
  a 
  nar- 
  

   row 
  (vertically) 
  linear 
  piece. 
  The 
  epimerum 
  is 
  membranous, 
  narrow, 
  

   but 
  wider 
  than 
  the 
  episternum. 
  The 
  coxa 
  and 
  trochantine 
  are 
  consol- 
  

   idated 
  in 
  one 
  large 
  oval-oblong 
  sclerite. 
  

  

  Mesopleurum. 
  (Fig. 
  5.) 
  Episternum 
  forming 
  one 
  large, 
  irregular 
  

   piece, 
  expanding 
  above 
  the 
  middle, 
  anteriorly 
  forming 
  a 
  triangle. 
  The 
  

   epimerum 
  is 
  much 
  smaller 
  and 
  semi-membranous. 
  The 
  trocliantine 
  is 
  

   large 
  and 
  long, 
  being 
  oblong-ovate; 
  coxa 
  as 
  long 
  as 
  the 
  trochantine, 
  but 
  

   narrower, 
  and 
  pressed 
  up 
  (so 
  to 
  speak) 
  beyond 
  it. 
  

  

  Metapleurum, 
  (Fig. 
  6.) 
  Much 
  shorter 
  than 
  that 
  of 
  the 
  mesothorax. 
  

   Episternum 
  much 
  narrower, 
  while 
  the 
  trochantine 
  is 
  broader 
  and 
  much 
  

   shorter 
  in 
  proportion; 
  otherwise 
  much 
  as 
  in 
  the 
  preceding 
  segment. 
  

  

  In 
  Termes 
  flavipes 
  (Fig. 
  4) 
  the 
  pro-episternum 
  is 
  represented 
  by 
  a 
  

   narrow 
  sclerite 
  situated 
  in 
  front 
  of 
  and 
  below 
  the 
  pronotum, 
  and 
  sep- 
  

   arated 
  from 
  the 
  sternites 
  by 
  a 
  suture. 
  The 
  epimerum 
  is 
  a 
  minute, 
  trian- 
  

   gular 
  sclerite 
  situated 
  over 
  the 
  coxa. 
  The 
  trochantine 
  is 
  large 
  and 
  

   long, 
  and 
  the 
  coxa 
  is 
  of 
  the 
  same 
  length. 
  

  

  Mesopleurum. 
  (Fig. 
  5.) 
  The 
  episternum 
  is 
  well 
  developed, 
  narrow, 
  

   curved, 
  triangular. 
  The 
  epimerum 
  is 
  much 
  smaller, 
  and 
  both 
  pieces 
  are 
  i 
  

   situated 
  obliquely. 
  The 
  trochantine 
  and 
  coxa 
  are 
  of 
  the 
  same 
  size 
  and
