flacherie. He was able to reproduce the same symptoms 

 experimentally in the gypsy moth, and also in the cater- 

 pillars of Vanessa urticae and Euproctis chrysorrhea , A 

 "brief description of the morphology and cultural character- 

 istics of the organism are given "by Paillot. He named 

 this "bacterium, which he says is a co"cco"bacillus, Bacillus 

 lymantricola adiposus , "because of its specific "disorgani- 

 sation" action on the adipose tissue of Porthetria ( lyman - 

 tria ) dispar. Paillot (1933) goes into quite some detail 

 in discussing the morphological variations of this organ- 

 ism.

BAC I LLUS MEG ATHER I UM De Bary 



Insect concerned: Lecanium corni. 



Benedek and Specht (1933) found the secondary "symbiont" 

 in diseased Lecaniidae to "be Bacillus megatherium , the 

 main "symbiont" "being a fungus, Torula lecanii corni i 

 n. sp. Both organisms were found free in the hemolymph of 

 the host. See Bergey's Manual of Determinative Bacteriol- 

 ogy* 5th edition, page 665, for a complete description of 

 Bacillus megatherium , which is widely distributed in the 

 air, soil, and putrifying material.

Bacillus megaterium bombycis 



Insect concerned: The silkworm, Bombyx mori . 



Sawamura (1906) lists this organism as one artificially 

 pathogenic to the. silkworm. The name "megaterium" is 

 prohahly a misspelling of megatherium .
