1859. Canthon depressipennis Le Conte, Coleoptera of Kansas and 

 N. M., p. 10. 



This species is recorded by Blanchard (I.e.) from Dakota 

 and Kansas, but no specimens are at hand from Nebraska.] 



Canthon praticola Le Conte. 



1859. Canthon praticola Le Conte, Coleoptera of Kansas and N. M., 

 pp. 10, 11. 



Specimens examined : 1 $ , 2 $ , from Haigler, Mitchell, 

 Gordon and Kearney, collected from May to August. Prati- 

 cola is a western species which is probably less common, or 

 absent, in the eastern part of the state. 



Canthon lecontei Harold. 



1868. Canthon lecontei Harold, Berl. Ent. Zeitschr., p. 68. 



Specimens examined : 1$ , from Haigler, July 6, and 1 ? , 

 July 4, collected by J. T. Zimmer. The character "clypeus 

 6-dentate, or 4-dentate" used by Dr. Horn in his table for the 

 separation of the closely similar species probiis and lecontei 

 is apparently unsatisfactory. Our Nebraska species is here 

 referred to lecontei rather than probus because of the car- 

 ination of the subhumeral stria. 



[Canthon vigilans Le Conte. 



1858. Cathon vigilans Le Conte, Journ. Acad. Nat. Sci. Phila., (2), 

 iv, p. 16. 



No Nebraska specimens of this species are at hand, but 

 since it is a rather widely distributed form, and is recorded 

 from Iowa, Missouri and Kansas, the writer has included 

 it in the synopsis.]
