  Subfamily 
  Cryptostemmatinae 
  

  

  A 
  number 
  of 
  general 
  characters 
  of 
  the 
  subfamily 
  are 
  mentioned 
  in. 
  

   the 
  introduction 
  and 
  in 
  the 
  key 
  to 
  subfamilies 
  and 
  we 
  may 
  add 
  that 
  

   these 
  insects 
  are 
  notable 
  for 
  their 
  vestiture, 
  being 
  clothed 
  above 
  

   with 
  a 
  very 
  fine 
  pilosity, 
  with 
  longer 
  hairs 
  on 
  wing 
  veins 
  and 
  

   costal 
  margin, 
  the 
  hairs 
  on 
  or 
  near 
  margins 
  of 
  thorax 
  also 
  are 
  longer 
  r 
  

   certain 
  of 
  them 
  sometimes 
  being 
  developed 
  as 
  bristles, 
  the 
  head 
  

   with 
  paired 
  bristles, 
  of 
  which 
  one 
  between 
  back 
  part 
  of 
  eyes, 
  and 
  

   about 
  three 
  from 
  lower 
  margins 
  of 
  eyes 
  to 
  clypeus 
  appear 
  to 
  be 
  

   present 
  in 
  all 
  the 
  species 
  (some 
  have 
  several 
  more 
  especially 
  on 
  base 
  

   of 
  beak) 
  ; 
  the 
  antennae 
  are 
  long-haired 
  throughout 
  (fig. 
  10). 
  The 
  

   under 
  surface 
  also 
  is 
  copiously 
  pilose, 
  the 
  sides 
  of 
  abdominal 
  seg- 
  

   ments, 
  especially 
  posteriorly, 
  with 
  longer 
  hairs, 
  and 
  the 
  tibiae 
  are 
  

   bristly. 
  The 
  male 
  genitalia 
  (described 
  in 
  keys 
  to 
  subfamilies 
  and 
  

   genera) 
  are 
  remarkable. 
  There 
  is 
  little 
  range 
  of 
  color 
  in 
  the 
  family 
  

   and 
  the 
  species, 
  whatever 
  shade 
  of 
  the 
  characteristic 
  family 
  colora- 
  

   tion 
  they 
  exhibit, 
  are 
  mostly 
  very 
  uniformly 
  colored 
  throughout.
