Caves of Monroe, Lawrence and Crawford counties; freipient in 

 Wyandotte. April 15-September 20. They occur only in the rp- 

 mote parts of the caves, where they may be found crawling rapidly 

 over mud, sand or rocks in danip localities. Like other Carabids, 

 these small blind beetles are supposed to be carnivorous. In Wyan- 

 dotte specimens of mites, spiders, springtails and harvestmen were 

 taken in the same locality as the beetles, and probably furnish the 

 latter a scanty supply of food.
