of the head and thorax more dense and fine than on the wing 
covers as he describes it. Moreover, his specimen as he says

From the table given below, Zilora canadensis Hausen has, 
therefore, been omitted. 
Thanks are due to Mr. Ralph Hopping who placed at my 
disposal his Ziloras, including long series of Zilora nuda 
Prov. and the new western species, Zilora occidentalis; to 
Mr. P. J. Darlington Jr. of the Museum of Comparative 
Zoology at Harvard University for access to all the Ziloras 
in that collection ; and to Mr. H. C. Fall for the use of all his 
material in this genus and for his unfailing advice in the 
revision of this genus. The types of Zilora alabamensis and 
occidentalis are in Mr. Fall’s collection.
