trace of paler margins. Mr. G. C. Champion has kindly 

 verified this indentification. The Ouedius was in company 

 with its congener Q. mesomelinus and a host of other beetles 

 which make their home in this kind of habitat, notably 

 Sphaeridium hipitstidatum, variety marginatum, Cercyon 

 terminatiim, C. quisquilitis, Microglossa suturalis (apparenth' 

 not recorded as an Irish species, though I believe my friend 

 Mr. E. Bullock has taken it at Killarney), Cilia silphoides, 

 (common), Philonthiis iimhratilis, P. cephalotes, P. longi- 

 cornis (common), P. ventralis, Lithocaris ochracea, Homalium 

 caesimi, H. Allardi (one), H. concinniim (a few), Megarthrus 

 affinis, Euconnus fimetariiis, Euplectiis sanguineus, Hister 

 xii.-striatiis, Sericoderus lateralis (common), Choleva fusca, 

 Mycetaea hirta, Micropeplus margaritae, Monotonia picipes, 

 Cartodere ruficollis (one specimen). I had previously found 

 this little species, which is recorded only from Belfast in 

 the " Irish List," under the bark of pine logs which were 

 lying near haystack refuse close to Finglas (in a similar 

 habitat, in the Tolka Valley, was Ptinella testacea, an un- 

 recorded Irish species), Crypto phagus pilosus, C. distin- 

 guendus, C. affinis, C. bicolor, Atomaria munda (a few), 

 Typhaea fumata (common), Ptinus crenatus, and Anthicus 

 floralis (common). 



In another locality near the village of Finglas many of 

 the above-mentioned species were found among vegetable 

 refuse, including Quedius cruentus variety virens, Atomaria 

 munda and Crypto phagus distinguendus. There were also 

 Leptacinns linearis (common), Xantholinus fulgidus, Phloeo- 

 bium clypeatum, Atomaria umbrina {fuscicollis. Marsh) and 

 a single specimen of Alexia pi lifer a, a species which has 

 not been recorded from this country. 



During visits to Howth some coleoptera were collected 

 on the south shore and cliffs between Sutton and the 

 Baily, a promising locality which should repay a close 

 search. The ground beetle Platyderus ruficollis occurs there, 

 a single specimen was found under an embedded stone on 

 the shore in November, 191 1, the only recorded occurrence 

 of this local species in Ireland. With it were the littoral rove- 

 beetles Cafius xantholoma and C. sericeus; Quedius nigriceps 

 is also an Irish rarity ; I found one running on the road at
