  In 
  addition 
  to 
  the 
  characters 
  in 
  the 
  key 
  the 
  following 
  may 
  be 
  

   mentioned 
  for 
  this 
  genus: 
  Head 
  and 
  prothorax 
  similar 
  to 
  those 
  of 
  

   Empicoris, 
  the 
  prothorax 
  however, 
  without 
  lateral 
  carinae. 
  The 
  

   mesonotum 
  is 
  produced 
  into 
  a 
  backw 
  T 
  ardly 
  directed 
  subtriangular 
  

   process 
  which 
  is 
  rounded 
  above, 
  the 
  metanotum 
  has 
  a 
  long 
  erect 
  

   slender 
  spine 
  at 
  apex, 
  and 
  the 
  basal 
  abdominal 
  tergite 
  has 
  a 
  much 
  

   shorter 
  spine. 
  Fore 
  tarsi 
  as 
  in 
  Stenolemus: 
  Basal 
  segment 
  of 
  beak 
  

   about 
  twice 
  as 
  long 
  as 
  second, 
  the 
  latter 
  subglobose; 
  the 
  third 
  joint 
  

   slender, 
  nearly 
  as 
  long 
  as 
  first. 
  The 
  reticulate 
  venation 
  of 
  corium 
  

   is 
  very 
  characteristic 
  (see 
  fig. 
  1).
