f86 s. ITO. 



Remarks. In 1903, Dietel (7) for the first time described this species 

 under the name of UrcJo Sctarlac italicac from the specimens on Setaria 

 viridis as well as on Setaria italica var. gcruiaiiica sent to him from Prof. 

 S. KUSANO, who had collected them in October 1901 in Tokyo. 



In 1906, Sydow and BUTLER (i) reported the same fungus from India 

 as infecting Setaria intermedia, S. italica, S. glatica and 5. vcrticillata. 



Mr. K. YOSHINO (i) having found the teleutospores of the present species 

 on Setaria italica var. gennanica in 1906 at Kumamoto, described it and 

 proposed to change the name of this species to Uroinyccs Setariac italicae 

 (Diet.). He made the following remarks : " It seems to me, although it 

 sometimes occurs abundantly in Kiushü, that damages caused by this fungus 

 are not so severe, because its appearance is always late in season in the 

 ripening period of the host-plant." 



The reasons why we have difficulty in finding the teleutostage specimens 

 of the present species may probably be due to the rarity of the teleutostage 

 or to the inconspicuousness of its sori.
