After this pamphlet had gonc to press I was able tu 

 study the contents of a newly published work on diseases 

 of tropical plants by G. Delacroix.') Hovvevcr the plants 

 hère mentioned do not warrant any change in my con- 

 clusions about the fungus, yet some peculiarities are 

 sufficiently important, to be mentioned hère. 



Delacroix himself investigated leaves, which he re- 

 ceived from the French West-Indian Islands, and which 

 were attacked by a disease called „rEnfer du Caféier". 

 He reports that the disease bas a great resemblance to 

 Koleroga; however he was not able to observe some charac- 

 terlstics; for instance: conidia were not seen and the 

 tissue was not gelatinous. 



Gallaud*) saw a similar disease in New Caledonia, 

 which appears to him to bc same as Koleroga.
