Moved from Large Rove Beetles.

This is a good photograph that allows me to identify this species as Philonthus debilis (Gravenhorst). Note the five punctures in each dorsal row of the pronotum, as well as the two pale basal antenommeres. You can also see (transparently from above) the deep notch in the last abdominal sternum of this male. Philonthus debilis is an adventive Palaearctic species, 4.5-5.0 mm in length.
