  Described 
  from 
  two 
  specimens 
  ; 
  a 
  male 
  collected 
  with 
  the 
  male 
  specimen 
  of 
  

   inflatus 
  near 
  Sacaton, 
  Arizona, 
  November 
  23, 
  1921, 
  by 
  H. 
  F. 
  Loomis, 
  and 
  a 
  

   female 
  collected 
  in 
  the 
  "nest 
  of 
  a 
  rat 
  among 
  rocks" 
  (probably 
  A^eo^owa) 
  near 
  

   Tucson, 
  Arizona, 
  January 
  2, 
  1897, 
  by 
  H. 
  G. 
  Hubbard. 
  

  

  This 
  species 
  should 
  probably 
  be 
  placed 
  after 
  punctatus; 
  the 
  carinate 
  elytra, 
  

  

  the 
  form 
  of 
  the 
  thorax 
  and 
  the 
  genitalia 
  distinguishing 
  it 
  from 
  that 
  species 
  

  

  and 
  all 
  others. 
  Tibial 
  punctures 
  are 
  found 
  in 
  most 
  of 
  the 
  species 
  of 
  Trox, 
  

  

  but 
  their 
  size 
  and 
  disposition 
  have 
  some 
  specific 
  importance. 
  In 
  scabrosus, 
  

  

  monachus 
  and 
  asper 
  these 
  punctures 
  are 
  small 
  or 
  entirely 
  lacking, 
  in 
  the 
  

  

  other 
  species 
  here 
  treated 
  the 
  rows 
  are 
  much 
  more 
  irregular 
  than 
  in 
  carinatus.

  Council

  it 
  was 
  decided 
  to 
  discontinue 
  the 
  section 
  of 
  formal 
  abstracts

  It 
  

   will

  replaced 
  by 
  a 
  section 
  devoted 
  to

  A 
  special 
  meeting 
  of 
  the 
  Botanical 
  Society 
  of 
  Washington 
  was 
  held 
  at 
  

   the 
  Cosmos 
  Club 
  on 
  Monday, 
  June 
  26, 
  1921, 
  to 
  hear 
  Prof. 
  J.

  Rock 
  of 
  the 
  

   Office

  Introduction, 
  who 
  had 
  just 
  returned 
  from 
  an 
  

   extended 
  trip 
  in 
  the 
  Orient, 
  where 
  he 
  traveled 
  up 
  the 
  rivers 
  of 
  Siam 
  and 
  

   Burma 
  and 
  through 
  the 
  forests 
  to 
  find 
  the 
  chaulmoogra 
  oil 
  trees. 
  This 
  oil 
  

   has 
  lately 
  been 
  used 
  in 
  Hawaii 
  for 
  the 
  treatment 
  of 
  leprosy 
  with 
  such 
  success 
  

   that 
  already 
  two 
  hundred 
  patients 
  have 
  been 
  declared 
  free 
  from 
  all 
  sumptoms 
  

   of 
  the 
  disease. 
  According 
  to 
  Hindoo 
  legend 
  and 
  literature, 
  moreover, 
  this 
  

   oil 
  has 
  been 
  used 
  for 
  a 
  thousand 
  years 
  by 
  the 
  natives 
  of 
  the 
  Far 
  East. 
  

  

  The 
  trip 
  was 
  made 
  by 
  Prof. 
  Rock 
  for 
  the 
  purpose 
  of 
  investigating 
  the 
  

   various 
  species 
  of 
  Taraktogenos 
  and 
  Hydnocarpus 
  and 
  to 
  collect 
  viable 
  seeds 
  

   for 
  germination 
  purposes, 
  especially 
  those 
  of 
  Taraktogenos 
  kurzii 
  which 
  seeds 
  

   are 
  known 
  to 
  produce 
  the 
  true 
  chatilmoogra 
  oil. 
  

  

  Hydnocarpus 
  anthelmintica 
  was 
  obtained 
  by 
  Prof. 
  Rock 
  in 
  Bangkok 
  and 
  

   Eastern 
  Siam. 
  Camp 
  was 
  established 
  in 
  the 
  northern 
  Lao 
  States 
  on 
  Mt. 
  

   Dai 
  Chom 
  Cheng 
  and 
  this 
  mountain 
  was 
  explored 
  for 
  economic 
  plants, 
  among 
  

   which 
  species 
  of 
  Castanea 
  or 
  chestnuts, 
  and 
  a 
  number 
  of 
  Qtiercus 
  or 
  oaks 
  were 
  

   secured. 
  He 
  followed 
  the 
  Meh 
  Ping 
  River 
  by 
  Lao 
  houseboat 
  to 
  Rahong, 
  a 
  

   journey 
  of 
  ten 
  days, 
  making 
  collections 
  on 
  the 
  way. 
  From 
  Raheng 
  he 
  crossed 
  

   overland 
  with 
  coolies 
  to 
  Moulmein, 
  Burma, 
  thence 
  to 
  Martaban, 
  where 
  

   Hydnocarpus 
  castanea 
  was 
  obtained.
