C. bimacnlatus, Piuiz., and is yet iiiiotlier addition to our list.* The 

 present paper was written cliiefly with a view to callincj attention to 

 this insect, at the same time it seemed desirable to place on record 

 some of the more interesting- species which have been recently found 

 on the northern and north-eastern shores of the lake. 



The following list is largely the result of two collecting trips to 

 the Shane's Castle district, organized by the " Royal Irish Academy, 

 Fauna and Flora Committee." On the first of these visits, in June, 

 1902, I was joined by my friend the late Mr. C. W. Buckle, and 

 together we secured most of the local species. At my suggestion, 

 Mr. Buckle made several subsequent excursions to Shane's Castle with 

 a view to the preparation of a joint paper on the beetle-fauna of the 

 district. It will be seen that eight of the species are unrecorded from 

 this coimtry, and at least three others must be re-instated in the Irish 

 list, on account of their occurrence at Lough Neagh. Except where 

 otherwise stated, the locality is Shane's Castle on the north-eastern 

 corner of the lake. 



Pelo])hila borealis, Payk., fairly common at Shane's Castle, found running 



on the shore, and also in flood refuse. Dyschirius obscurus, Gyll., locally 



abundant on sandy parts of the shore at Shane's Castle, also at Toonie. 



Pterostich^is anthracimis. 111. Anchome^ius yyiicans, Nic, in flood refuse and by 



sweeping, Mr. Biickle also found it under dead alder bark at Shane's Castle ; 



this species seems very local, and these are the only authentic Irish examples 



that I have seen. Bemhidium assimilc, Gyll., B. pallidipenne. 111., and B. 



argenteolum, Ahr., all locally common in sandy places. Tachypus Jiavipes, L., 



banks of the river Bann, near Toome. Trcchus micros, Herbst, a few specimens 



in flood refuse. Coelamhus novemlineatus, Steph. Hydroporus septentrionalis, 



Gyll., U. incognitus. Sharp, taken under flood refuse by Mr. Buckle. Cercyon 



marinus. Thorns, {aquaticus, Muls.), and C. minutus, MiUs. ; the latter insect 



must be re-instated in the Irish fauna. Aleocliara brcvipennis, Grav. Ocalea 



castanea, Er., under flood refuse ; Dr. Sharp has kindly examined the Lough 



Neagh specimens of this species, and he remai-ks that they are referable to a 



" variety of the old casta^iea, agreeing with what Waterhovise called 0. riviilaris." 



Ilyobates nigricollis, Payk. Calodera sethiops, Grav., Shane's Castle, also shaken 



out of reeds at Portmore Lovigh. Homalota insccta, Thoms., a single specimen 



of a large dark form at Shane's Castle in September, fide Dr. Shai-p. Homalota 



" sp. n. ?, near elongatula," fide Dr. Sharp; H. picipes, Thoms., Shane's Castle, 



not previously recorded from Ireland ; H. debilis, Er., taken by sweeping at 



Portmore and Shane's Castle ; H. gemina, Er., abundant on reeds at Portmore 



Lough, not previously recorded from Ireland ; H. divisa, Miirk., rare. Myr- 



mecopora stdcata, Kies., a single specimen of what Dr, Sharp considers may
