COLEOPTERA IN THE DUBLIN DISTRICT. 



BY J. N. H ALBERT, M.R.I. A. 



The rain storm which occurred on the night of 6th Septem- 

 ber was of the sudden and violent kind w^hich is likely to 

 cause the right conditions for finding insects amongst the 

 refuse swept down by river floods. As soon as the flood 

 had gone down a little I visited the River Tolka between 

 Finglas and Cardiff's Bridge in search of Coleoptera, and a 

 quantity of flood refuse was sifted out and brought home for 

 examination. 



To the coleopterist there is a pleasing element of luck 

 about this method of collecting, as there is always a chance 

 of finding local riparian species which are otherwise seldom 

 met with. On this occasion more than a hundred different 

 kind of beetles were found among the refuse, and some of 

 these are noteworthy, especially as so little is known of the 

 insect fauna of this interesting river valley. At least seven 

 species have not been previously recorded from the Dublin 

 district . These are Trechus micros, a ground beetle which is 

 known as Irish from two Ulster localities and the Mitchels- 

 town Cave, in Co. Cork ; MegartJirus affmis was reinstated 

 as an Irish species when Mr. E. Bullock found it at Killarney ; 

 it occurs also among vegetable refuse at Glasnevin ; Trogo- 

 phloeus rivularis, Cryptophagus distinguendus, C. affinis, 

 Coccinella heiroglyphica and Phyllotreta atra. There were 

 also the following species : — Notiophilus siihstriatus, Brady- 

 celliis similis, Bembidium obtiisiini, Sphaeridinm hipustulatiim
