  The 
  arrangement 
  and 
  classification 
  of 
  the 
  collection 
  has 
  received 
  

   much 
  attention. 
  Assistant 
  Entomologist 
  D. 
  B. 
  Young 
  has 
  sepa- 
  

   rated 
  the 
  Staphylinidae 
  into 
  their 
  major 
  groups 
  and 
  determined 
  

   many 
  species. 
  He 
  has 
  also 
  given 
  considerable 
  time 
  to 
  the 
  arrange- 
  

   ment 
  of 
  the 
  Syrphidae. 
  The 
  completion 
  of 
  the 
  catalogue 
  of 
  the 
  

   Hill 
  collection 
  occupied 
  much 
  time 
  during 
  the 
  past 
  year. 
  Miss 
  

   Hartman 
  also 
  assisted 
  in 
  the 
  preparation 
  of 
  this 
  catalogue 
  and 
  has 
  

   done 
  much 
  general 
  curatorial 
  work, 
  such 
  as 
  mounting, 
  labeling 
  and 
  

   caring 
  for 
  insect 
  specimens. 
  

  

  General. 
  The 
  tacit 
  limitations 
  of 
  earlier 
  years 
  confined 
  the 
  

   studies 
  of 
  the 
  economic 
  entomologist 
  to 
  insect 
  enemies 
  of 
  well 
  recog- 
  

   nized 
  farm 
  crops, 
  such 
  as 
  corn, 
  potatoes, 
  fruits, 
  or 
  to 
  those 
  forms 
  

   annoying 
  or 
  injurious 
  to 
  domestic 
  animals. 
  The 
  later 
  extensive 
  

   insect 
  depredations 
  upon 
  shade 
  and 
  forest 
  trees 
  have 
  served 
  to 
  em- 
  

   phasize 
  the 
  practical 
  importance 
  of 
  this 
  field. 
  The 
  more 
  recent 
  

   discoveries 
  that 
  malaria 
  and 
  yellow 
  fever 
  are 
  transmitted 
  by 
  mos- 
  

   quitos, 
  and 
  that 
  typhoid 
  fever 
  and 
  other 
  intestinal 
  diseases 
  may 
  be 
  

   conveyed 
  by 
  house 
  flies, 
  has 
  made 
  the 
  entomologist 
  a 
  most 
  welcome 
  

   ally 
  of 
  the 
  sanatorian. 
  Furthermore, 
  careful 
  investigations 
  of 
  in- 
  

   jurious 
  and 
  dangerous 
  insects 
  have 
  repeatedly 
  demonstrated 
  the 
  

   value 
  of 
  such 
  studies 
  as 
  a 
  necessary 
  preliminary 
  to 
  practical 
  con- 
  

   trol 
  work 
  on 
  the 
  farm 
  or 
  marsh, 
  in 
  the 
  orchard 
  or 
  even 
  about 
  the 
  

   home. 
  Prophylactic 
  measures 
  against 
  yellow 
  fever, 
  malaria 
  and 
  ty- 
  

   phoid 
  must 
  depend 
  in 
  large 
  measure 
  iipon 
  an 
  intimate 
  knowledge 
  of 
  

   the 
  habits 
  of 
  certain 
  insects 
  and 
  their 
  part 
  in 
  the 
  dissemination 
  of 
  

   the 
  dangerous 
  germs. 
  The 
  study 
  of 
  injurious 
  insects 
  is 
  by 
  no 
  means 
  

   completed. 
  There 
  is 
  great 
  need 
  of 
  investigations 
  that 
  can 
  not 
  be 
  

   adequately 
  conducted 
  with 
  our 
  present 
  resources. 
  The 
  exhibit 
  col- 
  

   lections 
  should 
  be 
  strengthened 
  by 
  a 
  series 
  of 
  well 
  executed 
  en- 
  

   larged 
  models 
  of 
  the 
  smaller, 
  more 
  injurious 
  insects. 
  Such 
  a 
  de- 
  

   parture 
  would 
  increase 
  the 
  practical 
  and 
  educational 
  value 
  of 
  the 
  

   entomologic 
  exhibits, 
  particularly 
  as 
  the 
  significance 
  of 
  some 
  of 
  

   the 
  more 
  recent 
  discoveries 
  can 
  not 
  be 
  adequately 
  portrayed 
  with- 
  

   out 
  such 
  aid.

  SECTION 
  

  

  The 
  present 
  Zoologist 
  did 
  not 
  enter 
  upon 
  his 
  duties 
  until 
  the 
  

   1st 
  of 
  February 
  last, 
  and 
  considerable 
  time 
  was 
  necessarily 
  devoted 
  

   to 
  becoming 
  acquainted 
  with 
  the 
  material 
  at 
  present 
  in 
  the 
  museum 
  

   and 
  with 
  its 
  most 
  urgent 
  needs.
