Tue following species were collected on my vacation trip, in 
1896. The Uredinee were determined by Dr. Dietel, and 
descriptions sent me in German, which I have translated. I am 
indebted to C. G. Pringle, L. M. Underwood, J. N. Rose, and F, 
L. Scribner for determinations of the host plants. To Mr. 
Pringle’s kind assistance and advice in Mexico the size of the 
collection is largely due. My time was almost entirely devoted 
to the Uredinez and Ustilaginez.
