STAPH YLINID^E. 



A great number of our native Staphylinidse are still nondescript, while 

 many of the described species are so imperfectly characterized as to render 

 their proper determination a matter of difficulty and uncertainty. The suc- 

 ceeding list is therefore necessarily incomplete. It might be very materially 

 lengthened by the inclusion of a number of generic records, but it seems 

 scarcely worth while to incorporate these at present. 

 Falagria dissecta Er. West Cliff. 

 F. VENUSTULA Er. Fort Collins, April, under boards. 

 Echidnoglossa monTicola Casey. Colorado, Casey. Possibly this is the 



species recorded from Veta Pass by Mr. Schwarz.

 ColpodoTa sordida Marsh. La Veta; Colorado Springs, June; Fort Col- 

 lins, March.

Xenodusa cava Lee. West Cliff; Pueblo; I took a species of this genus 

 from ants' nests at Canon City.
