  Report 
  of 
  the 
  President 
  

  

  The 
  Curator, 
  Dr. 
  Wheeler, 
  spent 
  the 
  month 
  of 
  July 
  in 
  the 
  

   Casco 
  Bay 
  region 
  of 
  Maine, 
  where 
  he 
  continued 
  his 
  studies 
  of 
  

   the 
  Formicidge. 
  His 
  results 
  are 
  published 
  in 
  the 
  Bulletin. 
  

  

  A 
  third 
  expedition 
  was 
  sent 
  to 
  Colorado 
  under 
  Mr. 
  

   Gneomar 
  von 
  Krockow 
  to 
  collect 
  fossil 
  insects 
  and 
  leaves. 
  

   While 
  circumstances 
  prevented 
  him 
  from 
  carrying 
  out 
  the 
  

   original 
  plans, 
  his 
  industry 
  resulted 
  in 
  the 
  addition 
  to 
  the 
  

   Museum's 
  collections 
  of 
  fifty 
  reptiles, 
  amphibia 
  and 
  fishes, 
  250 
  

   vials 
  of 
  insects, 
  and 
  other 
  invertebrates. 
  

  

  Professor 
  Filippo 
  Silvestri, 
  of 
  Portici, 
  Italy, 
  spent 
  several 
  

   weeks 
  of 
  study 
  at 
  the 
  Museum 
  and 
  later 
  collected 
  in 
  New 
  

   York 
  and 
  in 
  certain 
  of 
  the 
  western 
  states. 
  The 
  Museum 
  is 
  to 
  

   receive 
  a 
  duplicate 
  set 
  of 
  the 
  specimens 
  he 
  secured. 
  

  

  In 
  spite 
  of 
  the 
  demands 
  of 
  routine 
  work, 
  the 
  Curator 
  and 
  

   his 
  staff 
  have 
  continued 
  their 
  researches, 
  and 
  during 
  the 
  year 
  

   18 
  papers 
  have 
  been 
  published. 
  

  

  MOLLUSCAN 
  SHELLS 
  

  

  Department 
  of 
  Conchology. 
  — 
  The 
  only 
  notable 
  acces- 
  

   sion 
  to 
  the 
  conchological 
  collection 
  was 
  an 
  interesting 
  series 
  

   of 
  shells 
  from 
  the 
  Philippine 
  Islands, 
  obtained 
  through 
  ex- 
  

   change 
  with 
  the 
  Frankfort 
  Museum 
  of 
  Germany. 
  The 
  collec- 
  

   tion 
  numbers 
  4,330 
  specimens, 
  representing 
  477 
  species 
  and 
  

   varieties 
  carefully 
  identified 
  and 
  comprising 
  many 
  cotypes. 
  

  

  INSECTS 
  

  

  Department 
  of 
  Entomology. 
  — 
  The 
  larger 
  portion 
  of 
  the 
  

   Curator's 
  time 
  has 
  been 
  devoted 
  to 
  selecting 
  the 
  unarranged 
  

   material 
  of 
  North 
  American 
  Coleoptera, 
  cleaning 
  and 
  remount- 
  

   ing 
  the 
  same 
  and 
  providing 
  the 
  specimens 
  with 
  proper 
  labels. 
  

   About 
  9,000 
  specimens 
  have 
  been 
  treated 
  in 
  this 
  manner. 
  The 
  

   collections 
  have 
  been 
  poisoned 
  and 
  freed 
  from 
  museum 
  pests. 
  

  

  Among 
  the 
  important 
  accessions 
  should 
  be 
  mentioned 
  a 
  

   collection 
  of 
  ants 
  presented 
  by 
  Dr. 
  William 
  Morton 
  Wheeler, 
  

   one 
  of 
  the 
  three 
  largest 
  collections 
  of 
  Formicidae 
  in 
  existence. 
  

   It 
  contains 
  many 
  types 
  and 
  cotypes 
  and 
  nearly 
  every 
  species 
  

   is 
  represented 
  by 
  long 
  series 
  of 
  specimens 
  — 
  in 
  fact, 
  the 
  collec- 
  

   tion 
  represents 
  such 
  a 
  large 
  portion 
  of 
  the 
  family 
  Formicidae 
  

   that 
  all 
  future 
  additions 
  can 
  be 
  readily 
  intercalated.
