  Collections. 
  There 
  have 
  been 
  material 
  additions 
  to 
  the 
  collec- 
  

   tions 
  through 
  the 
  efforts 
  of 
  the 
  members 
  of 
  the 
  office 
  staff, 
  and 
  

   also 
  by 
  exchange 
  and 
  donation. 
  Through 
  the 
  courtesy 
  of 
  Dr 
  

   Otto 
  Niisslin 
  of 
  Karlsruhe, 
  Germany, 
  the 
  Museum 
  received 
  an 
  

   excellent 
  series 
  of 
  European 
  bark 
  beetles. 
  Mr 
  Henry 
  Bird, 
  of 
  

   Rye, 
  generously 
  donated 
  an 
  admirable 
  lot 
  of 
  reared 
  stem 
  borers 
  

   belonging 
  to 
  Hydroecia 
  or 
  closely 
  allied 
  genera, 
  a 
  number 
  of 
  

   these 
  forms 
  being 
  almost 
  unrepresented 
  outside 
  Mr 
  Bird's 
  excep- 
  

   tionally 
  line 
  collection. 
  The 
  work 
  of 
  arranging 
  and 
  classifying 
  

   the 
  Museum 
  collections 
  has 
  continued 
  whenever 
  opportunity 
  of- 
  

   fered. 
  Considerable 
  miscellaneous 
  work 
  has 
  been 
  done 
  upon 
  the 
  

   beetles 
  or 
  Coleoptera, 
  giving 
  special 
  attention 
  to 
  the 
  flea 
  beetles, 
  

   Halticini 
  of 
  the 
  Chrysomelidae 
  and 
  to 
  the 
  June 
  beetles, 
  Lachno- 
  

   sterna 
  and 
  its 
  immediate 
  allies 
  of 
  the 
  Scarabaeidae. 
  An 
  excellent 
  

   series 
  of 
  genitalic 
  mounts 
  was 
  made 
  in 
  this 
  latter 
  group. 
  

  

  The 
  value 
  of 
  the 
  collections 
  has 
  been 
  greatly 
  increased 
  by 
  mi- 
  

   croscopic 
  preparations. 
  Specimens 
  of 
  the 
  Scolytidae 
  received 
  

   from 
  Doctor 
  Niisslin 
  and 
  noted 
  above 
  were 
  put 
  in 
  balsam 
  mounts. 
  

   There 
  were, 
  in 
  addition, 
  two 
  hundred 
  such 
  preparations 
  of 
  gall 
  

   midges, 
  mostly 
  from 
  reared 
  material, 
  and 
  a 
  number 
  of 
  scale 
  in- 
  

   sects, 
  some 
  previously 
  unrepresented 
  in 
  the 
  collections, 
  which 
  

   were 
  similarly 
  treated. 
  The 
  value 
  of 
  this 
  material 
  is 
  much 
  en- 
  

   hanced 
  when 
  placed 
  in 
  such 
  preparations, 
  since 
  the 
  latter 
  are 
  per- 
  

   manent 
  in 
  character 
  and, 
  in 
  most 
  of 
  the 
  species 
  mounted, 
  neces- 
  

   sary 
  for 
  the 
  identification 
  of 
  the 
  insect. 
  

  

  The 
  series 
  of 
  plant 
  groups 
  designed 
  to 
  serve 
  as 
  an 
  embellishing 
  

   and 
  instructive 
  feature 
  of 
  the 
  enlarged 
  exhibit 
  now 
  in 
  preparation 
  

   are 
  practically 
  completed. 
  There 
  has 
  been 
  special 
  collecting 
  for 
  

   this 
  exhibit. 
  

  

  The 
  more 
  ample 
  facilities 
  of 
  the 
  new 
  quarters 
  bring 
  added 
  re- 
  

   sponsibilities 
  in 
  the 
  opportunity 
  they 
  offer 
  of 
  making 
  the 
  State 
  

   collection 
  of 
  insects, 
  both 
  for 
  exhibit 
  and 
  reference, 
  thoroughly 
  

   representative. 
  The 
  magnitude 
  of 
  such 
  a 
  task 
  is 
  appreciated 
  by 
  

   very 
  few. 
  The 
  Entomologist 
  recently 
  assembled, 
  with 
  the 
  coopera- 
  

   tion 
  of 
  recognized 
  authorities 
  in 
  various 
  groups, 
  the 
  best 
  obtainable
