i9oo.l ^A.T.'^V^^t.—Beeths of the D7ibli7i District. 2^9 



Amara rufoclncta, Dej.— One specimen found near the end of the 



North Bull sands. 



A. lucida, Duft. — Not common. 



Bembidium normannum, Dej. — Portmarnock, under stones on 

 the shore; B. aneum, Germ., and B. varium, 01., are not uncommon 

 under moss on the banks of the stream in the same locality. 

 *B. ani^Iicanum, vSharp.— Dodder banks, near Templeogue. I found 

 this northern species commonlj^ under stones in June, 1895. 



B. affine, Steph. — Rare, in the same locality as the preceding. 

 B, punctu latum, Drap.—Blessington and Killiney strand. 



Acpus marinus, Strom. — Shore at Dollymouut. 



Haliplus flavicollis, Sturm. — Royal and Grand Canals, common. 



Bidessus minutissimus, Germ. — I captured a specimen of this very 

 rare water-beetle amongst Water-Thyme {Elodea) in the River 

 Camac, near Clondalkin, on the 12th of last August. There would 

 seem to be some doubt as to the origin of the original British 

 specimens of this species, which were said to have been taken in 

 rivers near Cork (Wollaston, Ent. Mo. Mag., vi., p. 141.) But it now 

 proves to be rather widely distributed in Ireland, as I have taken 

 specimens in the Sheen River, near Kenmare, in the month of April. 



Ccelambus conf luens, F. — Quarry holes near Lucan and Clontarf. 



Hydroporus septentrionalis, Gyll,— Common in Lower I^ough

 pool on Kippure Mountain, iu the same locality where he discovered 

 Agabus anticus, Payk, in the summer of 1896 {Irish Nat., vi„ 86.) 



Cyrinus clongatus, Aube.— Raheny Ponds, &c. ; much rarer th&n 

 G. natator, in this district. 



O. opacus, Sahl.— Royal Canal, in early summer. 

 *HcIopliorus lYIuIsantl, Rye. -Portmarnock ; one in a salt-marsh. 

 *Octhe)t)ius auriculatus, Rey.— I first met with this local species 

 near Laytown, on the coast of Meath, Again, in the summer of 1898, 

 it occurred on the North Bull, under the mud in places where there 

 had been small shallow pools, along with numbers of 0. marinus, 

 0. bicolon and 0. piibescens. 

 *0. Lejolisi, Muls.-Greystones. This interesting species, but recently 

 ' added to the British list, was taken in some numbers by Mr. G. H» 

 Carpenter from stagnant rock-pools, near the coastguard station, in 

 the beginning of June, 1897. It has been recorded only from the 

 French coast, and the extreme S.W. of England.
