  OF 
  THE

  ENTOMOLOGIST

  understood 
  from 
  an 
  examination 
  of 
  the 
  accompanying 
  figure, 
  which 
  

   represents 
  a 
  transverse 
  section 
  through 
  the 
  proboscis 
  of 
  the 
  female 
  at 
  

   about 
  its 
  middle.* 
  

  

  The 
  labium 
  is 
  seen 
  wrapping 
  itself 
  nearly 
  around 
  the 
  other 
  parts. 
  

   Above 
  it 
  He 
  the 
  two 
  maxillae, 
  partly 
  inclosing 
  the 
  parts 
  above 
  it. 
  Above 
  

   them 
  are 
  the 
  two 
  mandibles, 
  

   and 
  above 
  these, 
  centrally, 
  

   is 
  the 
  hypopharynx, 
  with 
  

   its 
  thickened, 
  middle, 
  sup- 
  

   posed 
  saliva, 
  channel- 
  

   Above 
  this 
  is 
  the 
  labrum" 
  

   •epipharynx 
  — 
  the 
  epiphar- 
  

   ynx 
  of 
  an 
  omega-form,

   ing 
  the 
  labrum 
  closely 
  at- 
  

   tached 
  to 
  it. 
  With- 
  the 
  

   labrum-epipharynx 
  slightly 
  

   brought 
  from 
  its 
  position 
  as 
  

   shown 
  for 
  convenience 
  in 
  

   the 
  figure, 
  so 
  as 
  to 
  rest 
  on 
  

  

  the 
  hypopharynx, 
  the 
  channel 
  for 
  the 
  passage 
  of 
  the 
  blood, 
  as 
  has 
  been 
  

   described, 
  is 
  formed. 
  In 
  the 
  continuation 
  of 
  this 
  sucking-tube 
  into 
  the 
  

   head, 
  "in 
  the 
  posterior 
  part 
  of 
  the 
  head, 
  it 
  is 
  enlarged 
  in 
  a 
  large 
  

   pumping-organ, 
  which 
  forces 
  the 
  imbibed 
  fluid 
  backward 
  into 
  the 
  

   iDesophagus 
  and 
  stomach

  Uses 
  of 
  the 
  Mosquito. 
  

  

  I 
  have 
  spoken 
  of 
  the 
  mosquito 
  as 
  the 
  most 
  universally 
  annoying 
  of 
  all 
  

   ■our 
  insect 
  pests. 
  Why 
  then, 
  it 
  may 
  be 
  asked, 
  w^as 
  it 
  created, 
  and 
  does 
  it 
  

   serve 
  any 
  possible 
  good 
  in 
  the 
  economy 
  of 
  the 
  world? 
  

  

  The 
  naturalist, 
  as 
  his 
  acquaintance 
  with 
  nature 
  becomes 
  more 
  extended, 
  

   and 
  the 
  range 
  of 
  his 
  studies 
  widens 
  so 
  as 
  to 
  open 
  up 
  to 
  him 
  an 
  insight 
  

   into 
  the 
  interdependence 
  of 
  all 
  animated 
  nature, 
  is 
  led 
  to 
  accept 
  the 
  

   belief 
  that 
  nothing 
  was 
  made 
  in 
  vain, 
  and 
  that 
  not 
  a 
  single 
  one 
  of 
  the 
  

   typical 
  forms 
  now 
  in 
  existence 
  could 
  be 
  withdrawn 
  without 
  breaking 
  

   the 
  chain 
  that 
  binds 
  all 
  nature 
  together 
  in 
  one 
  harmonious 
  (if 
  properly 
  

   interpreted) 
  w^hole. 
  This 
  belief 
  brings 
  to 
  him 
  a 
  faith 
  that 
  compels 
  him 
  

   to 
  accept 
  as 
  of 
  use 
  whatever 
  object 
  owes 
  its 
  existence 
  and 
  preservation 
  

   to 
  the 
  hand 
  of 
  its 
  Creator 
  and 
  Guardian, 
  although 
  in 
  his 
  limited 
  knowl-
