Among other insects susceptible to this "bacterium are 

 several species of ants and crickets. Fowls, guinea pigs, 

 rabbits, cows, sheep, and man are refractory to infection, 

 "but the sewer rat dies in ~$-k days after a subcutaneous 

 inoculation with Coccobacillus acridiorum .

Insects concerned: Arctia caja ; Poecilus koyi ; Epacromia 

 strep ens ; the oriental roach, Periplaneta orientalis ; 

 Eurydema ornata ; Cleonus mendicus ; Chrysomela sanguinolenta ; 

 Anoxia australis ; Mel'olontha vulgaris ; Opartum sabulosum ; • 

 Cretonia aurata ; Porthesia chrysorrhoea ; the silkworm, 

 Bombyx mori ; Acridium aegyptium Hydrophilus ; Dystiscus ; 

 Cvhister ; Notonecta ; Nepa ; ' Ranatra. 



The caterpillars of Arctia caja L. , which were extremely 

 abundant in the vineyards of Southern France, were almost 

 completely wiped out "by two diseases. One disease was 

 caused "by the fungus, Empusa aulicae , the other "by a "bac- 

 terium, Coccobacillus cajae . The organism, which is 

 apparently allied to Coccobacillus acridiorum d'Herelle, 

 was obtained "by Picard and Blanc (1913a) from the "blood of 

 diseased caterpillars and the disease was experimentally 

 reproduced.
