Johnson and Halbert — A List of the Beetles of Ireland. 563 



C. collaris, Herbst. 



TJxstek. 



Donegal (Portsalon, '94 J. 2, coll. Sn.).— Antrim (Eathlin, '97 

 Hr. ; Ballycastle, T.).—" Ireland, Tardy Coll." (Fg. MS.). 

 Yery rare. 



Dyschirius thoraeicns, Eossi. 

 Ulstke. Leixstee. 



Derry (Foyle dist., '00 B.).— Longh Is^eagh ('47 W. 2, coU. H.).— 

 Louth (Estuary of the Boyne, '94 J. 2, coll. C.).— Dublin (Port- 

 mamock and Portrane, '53 E"n. ; Eusb, Sp.). 



Local, but probably more widespread than the above localities 

 indicate. The records, Armagh ('87 J. 1 ; '88 J. 2), are to be deleted. 



D. obscurus, Gyll. 



Ulstee. 



Armagh (Lough JN'eagh shore at Maghery, '95 J. 2, 3). — "Mr. 

 Haliday informs me that he has captured it on the sandy shores of 

 Lough IS'eagh " ('54 Ds.). 



Extremely local. After many fi'uitless searches, one of us suc- 

 ceeded in rediscovering this rare species at L. ]^eagh, where it was 

 found in company with Blediiis stihterraneus, on which it evidently 

 preys. Its rediscovery at L. Neagh is most interesting, as it is the 

 only place in the British Islands in which it is known to occur, though 

 Mr. G. C. Champion detected specimens in an old collection which was 

 supposed to have been made iu Scotland. The European range of this 

 species is curiously suggestive of a "relic" fauna, as it has been 

 recorded fi'om the coast of the Xorth Sea, also the Baltic, Black, and 

 Caspian Seas (Ganglbauer), and Picardy (Acloque). The fi-esh-water 

 shrimp My sis relicta is regarded by manj as a relic ; and it also occurs 

 in Lough ^S'eagh, Scandinavia, Eussia, and Korth America, while allied 

 forms of Mysis have been described fi'om the Caspian Sea. 



D. impunctipennis. Daws. 



Ulstee. Comnaught. 



Donegal (Buncrana, '95 Wr. ; Coolmore, '95 J. 1). — Antrim 

 (Eathlin '97 Hr.). — Sligo (Enniscrone and Bosses Point, J.). 



Mr. J. .J. Walker records this species as locally abundant at Bun- 

 crana ; it occurred in company with Bledius arenarius at Coolmore.
