Bacillus pluton . " Burns ide suggests that Bacillus pluton , 

 Streptococcus apis , and Achromo"bacter ( Bacterium ) eurydice 

 are variants, or stages in the life history, of Bacillus 

 alvei. Bergey's Manual (5th ed. , 1936, page 517), gives a 

 separate description for Achromobacter eurydice .

AcHROMOBACTER HYAL 1 NUM Bergey et al. 



Insect concerned: The American cockroach, Periplaneta 

 americana . 



Hatcher (1939) states that " Acromobacter hyalinum 

 (Jordon)" was one of the species of "bacteria she isolated 

 from the fecal matter of Periplaneta. The generic name 

 of this organism was probably misspelled and no doubt was 

 meant to be Achromobacter . According to the 5"th edition 

 of Bergey' s Manual, 1939, page 505, Bacillus hyalinus 

 Jordon ( Achromobacter hyalinum Bergey et al. ) is possibly 

 a synonym for Achr omoba c t er delicatulum (Jordon) Bergey 

 et al. In the first edition of Bergey' s Manual, 1923, 

 page 138, the name Bacillus hyalinus Jordon, the chief 

 habitat of which is water, was renamed' Achromobacter 

 hyalinum by Bergey et al. Apparently it is this organism 

 which Hatcher found in the roach, Periplaneta americana . '

Achromobacter larvae (stutzer and Wsorow) Bergey et al. 



Insect concerned: Euxoa segetum . 



This organism, isolated by Stutzer and Wsorow (1927) 

 from the intestinal tract of normal caterpillars of Euxoa 

 segetum , was named by its discoverers Ent ero -bacillus 

 larvae, and was so designated in the 3& edition of Bergey 's 

 Manual, 1930, page 227. However, in the 5th edition of 

 Bergey' s Manual, 1939, page 517, it is described under 

 the name Achromobacter larvae. Besides this species, 

 several other species of bacteria were found in the intes- 

 tinal tracts of the normal caterpillars.
