  Called 
  "small-headed 
  flies" 
  because 
  of 
  the 
  unusually 
  small 
  head 
  com- 
  

   pared 
  with 
  the 
  large 
  hump-backed 
  thorax 
  and 
  inflated 
  abdomen. 
  They 
  

   are 
  the 
  "Acroceridse" 
  of 
  previous 
  list, 
  are 
  rare, 
  the 
  larvas 
  are 
  parasitic 
  

   upon 
  spiders 
  or 
  their 
  egg 
  sacs, 
  and 
  they

  fasciata

  Philadelphia, 
  bred 
  from 
  "Lycosa

  a 
  spider 
  

   which 
  also 
  occurs 
  in 
  New 
  Jersey. 
  

  

  Family 
  BOMBYLIID.F. 
  

  

  These 
  are 
  the 
  "bee-flies," 
  which 
  derive 
  their 
  common 
  name 
  from 
  the 
  

   fact 
  that 
  they 
  are 
  more 
  oi 
  less 
  covered 
  with 
  dense, 
  diverging 
  whitish 
  or 
  

   yellow 
  hair, 
  giving 
  them 
  a 
  close 
  resemblance 
  to 
  certain 
  bees. 
  Many 
  

   occur, 
  hovering 
  over 
  bare 
  places 
  in 
  early 
  spring, 
  others 
  are 
  found 
  on 
  

   flowers, 
  often 
  poised 
  in 
  mid-air 
  between 
  or 
  over 
  them. 
  One 
  series 
  

   resembles 
  the 
  bumble-bees 
  and 
  has 
  a 
  long 
  pointed 
  proboscis; 
  the 
  other 
  is 
  

   more 
  slender, 
  the 
  abdomen 
  tending 
  to 
  become 
  flattened, 
  with 
  a 
  short 
  

   proboscis 
  and 
  much 
  less 
  contrasting 
  colors. 
  

  

  The 
  larvae 
  are 
  parasitic 
  or 
  partly 
  predatory. 
  Some 
  are 
  true 
  parasites 
  

   in 
  lepidopterous 
  larvae; 
  others 
  feed 
  on 
  the 
  egg-pods 
  of 
  grasshoppers 
  

   while 
  yet 
  others 
  feed 
  in 
  nests 
  of 
  bees, 
  destroying 
  first 
  the 
  bee 
  egg 
  or 
  

   larva 
  and 
  then 
  feeding 
  upon 
  the 
  food 
  stored 
  for 
  it. 
  

  

  They 
  are 
  never 
  harmful 
  to 
  growing 
  vegetation, 
  hence 
  may 
  be 
  classed 
  

   as, 
  on 
  the 
  whole, 
  beneficial.
