 H. arenarius, Kies.

Down (Strangford Lough, Ht., coll. B,). — Dublin (Baldoyle and 

 Portmarnock, H. coll.). 



The identity of the Heterocerus recorded in the Dublin list ('53 

 Hn.) as H. femoralis, Kies., and later ('55 H. 1) as M. arenarius, Kies., 

 has not been definitely ascertained. Some of the Dublin specimens, 

 from the Haliday collection, have been examined by Mr. G. C. 

 Champion, ^vho suggests that they may be identical with H. rectus, 

 Wat. As there would seem to be some doubt as to the identity of the 

 M. femoralis of British collections,^'' it seems best to record the Irish 

 species as abore, especially as the jjame was first applied to the Irish 

 specimens. 



H. marginatus, F. 



UlSTEE. CoNXAUaHX. 



Donegal (Buncrana, '95 AYr.). — Antrim (Belfast, J., coll. Pn.).— - 

 Sligo (Enniscrone, J.). 



Bare. Mr. J. J. Walker records it as occuiTing plentifully at 

 Buncrana in company with Bledius spectahilis, " yarying to a handsome 

 unicolorous dark fuscous form, with the usual yellow markings on 

 elytra quite obsolete." 



H. britannicus, Kuw. 

 Ulstee. Mtjnstee. 



Down (river bank between Comber and Strangford Lough,- Ht., 

 coll. B.). — Cork (shore of the. creek of the Owenberg Eiver, Cork 

 Harboui', '55 H. 1). 



Mr. Haliday 's specimens, recorded as H. MarsJiami, were found in 

 company with A'i'ims, Micralymma, and other local insects. Mr. 

 C. "W. Buckle took forty specimens in an area of less than two square 

 feet, their borings occmTed at about' high- water mark, and were from 

 an inch to an inch and a-half deep in the sand. There is an example 

 in the Haliday collection labelled " Clifden shore " which, Mr. Buckle 

 informs us, may be a part of the shore near Bangor, locally known by 

 that name. We are indebted to Mr. G. C. Champion for the verifica- 

 cation of the Haliday specimens. 



* Mr. G. C. Champion informs us that specimens of a Seierocerus, \vhich had 

 been representing H. femoralis in his collection, were reported not to he that 

 species by Herr Kuwert.
