SYMBIOTES DURYI, A NEW SPECIES OF 

 ENDOMYCHIDAE.^ 



L. B. Walton. 



(Contributions from the Biological Laboratory, Kenyon College, No. 7.) 



The genus Syinbiotes 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 Rhymhus 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 Gambler, O., which 

 through acquaintance \vith 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 vScience 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 Avhich was carried into effect at the ineeting, 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 



iRead before the meeting of the Ohio Academv of Science, Columbus, 

 December 1, 1911.
