of this genus are mostly found on sandy shores, and feed on 

 Staphylinidae and Heteroceri. 



D. thoracicus, Ross. — One afternoon I found a quantity of this 

 species going in and coming out of a muddy place close to the bridge 

 at Kingston-on-Thames, doubtless in search of Heteroceri. " Sandy 

 "places on the coast, under stones, &c, in damp places; uncommon; 

 "Deal" (G. C. Champion, Kent and Surrey Coleoptera). "Marshy 

 "hollows and sandhills, Deal" (C. G. Hall). Wallasey sandhills 

 (R. Wilding). " Rather common on the maritime sandhills, generally 

 " in damp places, both on the Lancashire and Cheshire coasts " (W. 

 E. Sharp). " Common on the Crosby shore and Wallasey sandhills " 

 (Dr. Ellis). "Met with on the sands at Bournemouth" (R. Gillo). 

 Ireland : " This species is recorded from near Dublin " (Rev. F. W. 

 Johnson, Armagh). 



D. impunctipennis, Daws. — " Sandy places on the coast, rare; Deal" 

 (G. C. Champion, Kent and Surrey Coleoptera). "Common on the damp 

 " sand left by the retiring tide on the shores of the Bristol Channel in 

 " the spring and early summer. I have never found it under seaweed, 

 " but singly, hunting about after small Staphs, and such like prey. 

 " On more than one occasion I have caught it in the act of dragging 

 " off an unfortunate individual in this way " (R. Gillo, Bath). " I have 

 "taken it in similar localities as the preceding species, but it seems 

 " to be rarer on the Lancashire than the Cheshire shores. I have 

 " never taken either anywhere else than on the coast " (W. E. Sharp). 

 " Abundant on the Crosby shore, above high-water mark ; spring." 

 (Dr. Ellis, Liverpool Coleoptera). "Under drift-wood, Crossby shore" 

 (R. Wilding). 



D. nitidus, Dj. — The largest of the Dyschirii. " Occasionally found 

 " on the Crosby, Hightown, and Wallasey shores" (Dr. Ellis, Liver- 

 pool Coleoptera). " Running in the bright sunshine on the salt marshes 

 " at Puddington, Cheshire " (R. Wilding). " I have taken this species 

 " on the salt marshes of the Dee, but not commonly " W. E. Sharp). 



D. extensiis, Putz. (elongatulus, Daws.)—-" Sandy places on the
