obviate  this  loss  of  help.  Koebele  and  Perkins,  as  well  as  the 
Sugar  Planters’  Association,  who  largely  furnished  the  means 
may  be  well  satisfied  with  the  results  obtained. 
From  a scientific  point  of  view  the  results  have  been  very  good. 
It  is  a matter  of  hundreds  of  descriptions  of  new Hymenopterons 
parasites  together  with  their  hosts  also  largely  new,  and  with  the 
biological  observations  there  will  be  added  an  excellent  contribu- 
tion to  the  knowledge  of  the  families  of  Diptera  (Pipunculidae) , 
Coleoptera  (Stylopidae) , which  are  little  known  and  there  will  be- 
come known  a new  family  of  Lepidoptera  ( Epipyropidae ) of 
singular  structure  and  habits  all  in  all  our  knowledge  of  Aus-* 
tralian  Cicatidae  and  Fulgoridae  and  their  parasites  will  be  greatly 
enriched. 
The  major  portion  of  the  work  on  these  insects  has  been  written 
by  Perkins  and  Kirkaldy  and  a smaller  part  by  Terry,  Swezey 
and  Muir,  who  are  entomologists  of  the  Sugar  Planters’  Associa- 
tion laboratory ; complete  they  form  two  volumes  which  I consider 
among  the  most  important  publications  in  our  time  on  a subject 
of  agricultural  entomology,  though  it  may  now  perhaps  be  equalled 
or  even  considerably  surpassed  by  what  is  being  achieved  in  the 
United  States  in  regard  to  Lymantria i dispar,  L,,  and  Euproctis 
chrysorrhoea,  L.,  under  the  direction  of  Prof.  L.  O.  Howard. 
LEPIDOPTERA. 
I have  already  mentioned  that  about  the  end  of  1883  Riley  in- 
troduced in  the  United  States  from  England  Apanteles  glomera- 
tns  which  became  acclimated  and  spread  rapidly. 
OMIODES  ACCEPTA  (bUTL.). 
This  is  a species  of  butterfly  of  the  family  Puralidae,  native  of 
the  Hawaiian  Islands,  which  in  the  larva  state  injures  the  sugar 
cane  folding  the  edges  of  the  leaf  against  each  other  and  eating 
parts  of  it.  The  harm  done  by  it  may  at  times  become  quite 
serious. 
This  Lepidopteron  had  been  attacked  by  several  species  of  in- 
digenous parasites  but  Koebele  introduced  several  others  besides, 
of  which  Macrodyctium  omiodivorum  Terry  is  the  most  impor- 
tant, having  destroyed  alone  as  much  as  75%  of  larvae  in  one 
locality.  The  year  of  introduction  and  origin  of  this  species 
are  not  known  with  certainty.  Chalcis  obscurata  Walk,  has  been 
introduced  in  1895  from  Japan  and  in  1896  from  China  and 
spread  rapidly  in  the  Hawaiian  Islands  parasitising  besides 
Omiodes  other  Lepidopterous  chrvsalides  (Phlyctaenia,  Casoecia, 
Plusia,  Tortrix)  : T richo  gramma  pretiosa  Riley,  a North  Ameri- 
can species,  was  also  introduced  perhaps  about  1898  by  Koebele 
and  is  now  well  spread  destroying  eggs  of  various  species  of  Lepi- 
doptera including  those  of  Omiodes.
