SYMBIOTES DURYI, A NEW SPECIES OF 
ENDOMYCHIDAE . 1 
L. B. Walton. 
(Contributions from the Biological Laboratory, Kenyon College, No. 7.) 
The genus Symbiotes of the family Endomychidae belonging 
to the Coleoptera has prior to the year 1908, been unrepresented 
by any described species from North America although Leconte 
and Horn (1883) erroneously referred Rhymbus ulkei Crotch, and 
Rhymbus minor Crotch, to this genus in their classification of the 
Coleoptera of North America. 
Consequently it was with much interest that the writer in 
November, 1907, collected two specimens at Gambier, O., which 
through acquaintance with the European representatives of 
Symbiotes were immediately referred to that genus. This 
occurred only a few days prior to the annual Thanksgiving meeting 
of the Ohio Academy of Science at Oxford, presided over by the 
President, Mr. Charles Dury, of Cincinnati, an indefatigable 
collector of Coleoptera as well as a keen student of nature. It 
therefore seemed most appropriate that the name duryi should be 
conferred upon the species which had so opportunely presented 
itself, an idea which was carried into effect at the meeting, the 
specimens also being exhibited. 
This was noted in the Proceedings of the Academy for 1907 
(mailed about June 1, 1908). Blatchley, (1910), after communi- 
cating with the writer as to the systematic arrangement of the
