REPORT  OF  SUPERINTENDENT  OF  ENTOMOLOGY 
FOR  APRIL,  1909. 
Honolulu,  Hawaii,  May  1,  1909. 
Honorable  Board  of  Commissioners  of 
Agriculture  and  Forestry  of  the 
Territory  of  Hawaii. 
Gentlemen : — The  following  report  covers  the  work  of  the  Divi- 
sion of  Entomology  during  the  month  of  April : 
HONOLULU  INSPECTION. 
We  boarded  twenty-five  vessels  and  found  live  vegetable  mat- 
ter on  nineteen  of  them.  This  was  disposed  of  in  the  following 
manner : 
Disposal  with  Principal  Causes.  Lots.  Parcels. 
Passed  as  free  from  pests 560  32,595 
Fumigated  before  releasing 25  no 
Burned 7 15 
Ordered  returned  1 5 
Dipped  in  Bordeaux 1 ' 2 
Dipped  in  Formalin 1 1 
Total  examined  595  32,728 
The  articles  destroyed  included  fruit  from  the  Orient;  orange 
trees  in  the  mails  from  Japan  badly  infested  with  fungus  and  un- 
known leaf  miner;  maggoty  turnips,  and  a staghorn  fern  from 
Australia  alive  with  caterpillars  and  a huge  colony  of  ants.  What 
we  have  seen  of  the  ant  it  did  not  look  familiar  and  all  stages 
were  represented.  A normal  dose  of  hydrocyanic  acid  gas  failed 
to  kill  those  of  them  that  were  hidden  in  the  folds  of  the  plant, 
and,  to  avoid  a risk,  it  was  burned. 
Our  usual  reasons  induced  the  fumigation  of  various  plants 
with  the  following  notable  examples : 
The  “Concord”  brought  21,000  cocoanuts  from  Fanning  Is- 
land. Upon  examination  these  were  found  clean  and,  as  we  were 
assured  besides  that  every  one  of  the  nuts  spent  about  48  hours  in 
the  sea  before  being  loaded,  they  were  passed.  In  course  of  their 
unloading,  however,  some  cocoanuts  were  observed  that  had  still 
retained  green  color  and  upon  close  inspection  were  found  inhabit- 
ed by  a species  of  “snow”  scale  ( Hemichionaspis  minor).  These,
