The four last-mentioned species are all much alike in morphologi- 

 cal respect; their st. II &. Ill are developed on the same host and are 

 not to be distinguished except by cultivating experiments; so Rostrup 

 also unites them into one species which he names "Rergraesrust" (R 

 04 a 39).

It is common all over the country on many different host-plants, 

 it has, however, formerly been still more common, year after year 

 causing great damage to the cereals. Scheler already worked ardently
