  Family 
  CECIDOMYIID^. 
  

  

  Small, 
  slender, 
  mosquito-like 
  flies 
  with 
  broad 
  wings, 
  long 
  slender 
  an- 
  

   tennae 
  with 
  cylindrical 
  or 
  bead-like 
  joints, 
  the 
  males 
  often 
  with 
  whorls 
  

   of 
  long 
  hair 
  on 
  the 
  segments, 
  whence 
  they 
  are 
  known 
  as 
  verticillate. 
  On 
  

   the 
  whole 
  the 
  insects 
  are 
  fragile 
  in 
  appearance, 
  slow 
  in 
  flight, 
  and 
  they 
  

   are 
  popularly 
  known 
  as 
  "gall-gnats" 
  or 
  "gall-midges," 
  because 
  the 
  larvae 
  

   of 
  many 
  species 
  produce 
  abnormal 
  growths 
  or 
  galls 
  on 
  a 
  great 
  variety 
  of 
  

   vegetation. 
  These 
  larvge 
  are 
  small, 
  elongate-oval 
  legless 
  grubs, 
  bluntly 
  

   pointed 
  at 
  both 
  ends, 
  often 
  with 
  a 
  chitinous 
  process, 
  known 
  as 
  a 
  breast- 
  

   bone, 
  on 
  the 
  under 
  side, 
  near 
  the 
  anterior 
  end. 
  

  

  Some 
  of 
  the 
  species 
  belonging 
  here 
  are 
  among 
  the 
  most 
  destructive 
  of 
  

   those 
  in 
  the 
  order, 
  and 
  the 
  injury 
  caused 
  by 
  them 
  is 
  of 
  the 
  most 
  diverse 
  

   character. 
  In 
  some 
  cases 
  there 
  is 
  a 
  true, 
  gall-like 
  swelling 
  of 
  the 
  tissue; 
  

   in 
  others 
  it 
  is 
  a 
  characteristic 
  crippling 
  or 
  folding 
  of 
  a 
  leaf 
  or 
  of 
  a 
  grow- 
  

   ing 
  tip, 
  or 
  even 
  a 
  mere 
  swelling 
  of 
  the 
  tissue. 
  Some 
  species 
  produce 
  no 
  

   visible 
  swellings 
  or 
  distortions 
  at 
  all, 
  and 
  some 
  feed 
  in 
  or 
  on 
  seeds, 
  

   causing 
  rather 
  a 
  shrivelling 
  than 
  a 
  swelling. 
  Much 
  attention 
  has 
  re- 
  

   cently 
  been 
  paid 
  to 
  these 
  insects 
  by 
  Mr. 
  William 
  Beutenmuller, 
  of 
  the 
  

   American 
  Museum 
  of 
  Natural 
  History, 
  who 
  has 
  been 
  good 
  enough 
  to 
  pre-
