very large specimen oi A. dubia, previously recorded by Professor McNab 

 from same locality. Otiorrhynchtis ligneus, Alophus triguttattis and 

 Bradycelhts harpalimis were almost the only species taken during a day's 

 collecting on the hill near Carrickmines. In an old pond overgrown 

 with vegetation in the Santry Demense, Bagons alismatis and Poophagns 

 sisymbrii occurred in numbers. The following species, though unrep- 

 resented in the Dublin and Wicklow list of 1878, are apparently common 

 in suitable places, i.e. — Ocypus ater (sea-shore), Qiiedhis setnicsneus (coast sand- 

 hills), Cercyon flavipes, C. pyginceiis, Conosoma lividiiin, Philonthus piidlus 

 (Dublin Mountains, etc.), Stemis ossium, S. nitidi us cuius, S. pallitarsus, S. 

 piibescens, ScydmcBUus collatis, Enicmus transverstts, Corticaria fusaila, C 

 elongata (Drumcondra), Ceuthorrynchtts inarginatus, C. pimctiger. 



Mr. G. lyow collected some Coleoptera at Dundrum including three 

 uncommon species, i.e. — Omosita discoidea, TrophipJioyjis viercuralis and 

 Scaphisoina boleii. In the autumn of 1893 I was fortunate in retaking two 

 local insects, Liosoma ovatului/i, var. collaris, and Laf/iprosana concolor at 

 Woodlands near Lucan, where the first Irish examples were collected 

 some years ago by Dr. Power. I have also a specimen of Cholrua agilis, 

 taken in a damp place at Tibradden in the September of the previous 

 year. There are probably more noteworthy species in my collection 

 still awaiting identification, and a few, although named, I should prefer 

 to get verified before recording.

Coleoptera from the North of Ireland.— That successful 

 observer, Mr. R. Welch of Belfast, was kind enough to send some 

 Coleoptera collected by him in various localities in the north of Ireland 

 during the past season. The best thing amongst these was Cercyon 

 aquatiais, Muls., taken in damp moss on Cave Hill near Belfast. It 

 has not, I think, been previously noted from Ireland. He also took 

 on Cave Hill the following species : — Hypera trilineatus, Barypeit/ies 

 stdcifrous, and Niptus hololaicus. At PORTSAI^ON, Co. Donegal, Anchoinenus 

 marginaius, Oliorrhynchtis atroapterus., Cneorrhiftus gei/iitiatus, Gastrophysa 

 polygoni and Serrica brunnea. At Woodburn G1.EN, Co. Antrim, one 

 specimen of the rather local Choleva agilis and Phccdon tumidulus. Near 

 BEIvFAST, Alophus triguttatus, Barynotus nicc7-ens, Bruchus atomarius, Exo7nias 

 areneiforfnis ; and in the People's Park near Belfast, Ccclainbus inipressopunc- 

 tatus, Philhydrus niariiinius, Deronectes xii-pustulatus, and D. depressus.

The Stridulation of Corixa, — The stridulation ot Corixa having 

 been seldom remarked, I think it may be interesting to relate that nearly 

 fifty years ago the late Dr. Robert Ball brought under the notice of the 

 Zoological Section of the British Association at the Cambridge INIeeting, 



1845, the fact that Corixa striata produced loud sounds while immersed 

 in water. Dr. Ball stated that the sounds, which had been heard by 

 Miss M. Ball a few years previously, had since been heard both by Miss 

 M. Ball and himself A very interesting and more detailed account of 

 the observations is given in a note from the original observer and 

 communicated by Dr. Ball to the Annals and Magazine of Natural History, 



1846. Miss M. Ball noticed two distinct sounds, which agrees with INIrs. 

 Thompson's account of the stridulation of a Corixa {Irish Naturalist, 

 1894, p. 114). One of the sounds is probably due to the movement of the 

 teeth on the feet as shown by Mr. G. H. Carpenter {Irish Naturalist, 

 December, 1S94), but further observations seem necessary to arrive at a 

 satisfactory explanation of the other sound, which Miss M. Ball states to 

 be accompanied by a movement of the body from side to side.

[I am very grateful to my friend Mr. Nichols for having discovered 

 this early Irish observation on the stridulation of Corixa. Like Mrs. 

 Thompson, and Dr. Schmidt-Schwedt, as quoted in my paper. Miss
