Serrat I A PLYMOUTH ENS is (Migula) Bergey et al. 



Insect concerned: The cricket, Neombius fasciatus, var. 

 fasciatus . 



The growth of Serrat ia plymouthensis is characterized 

 "by a "bright red pigment similar to Serratia marcescens , 

 "but is a visible gas producing type. (See Bergey 's Manual, 

 1939? 5th ed. , page U25, for a description of Serratia 

 plymouthens is . ) 



This "bacterium was found by Steinhaus (19^1) to occur 

 in the alimentary canal of nearly every specimen of the 

 above-named cricket which he examined. The crickets were 

 collected in nature in a meadow near Columbus, Ohio.
