 of diseased white caohage "butterflies. From the same 

 source, he isolated 8 other "bacteria. (See Bacillus pieris 

 fluorescens . ) He considered these "bacteria to "be second- 

 ary invaders, the primary invader, Apanteles glome ratus , 

 a parasitic wasp, "being the predisposing factor in the 

 "bacterial infection of the white cahhage "butterfly.
