48 The Irish naturalist. January, 1907. 



Pyrenean weevil Otiovrhynchiis auropanctatus, not an unex- 

 pected occurrence, however, seeing that the only known British 

 locality for this insect is our east coast from Wicklow to Down. 1 

 Elsewhere it has been recorded from the Pyrenees, and the 

 Auvergne Mountains in Central France. 



Although Lambay has been inhabited for a very considerable 

 time, yet there are apparently extremely few species which owe 

 their occurrence there to the direct action of man. The ground- 

 beetle Lcemostenas complanatus, with a wide distributional range 

 and occurring usually in suspicious localities, may be mentioned 

 in this connection. The common cellar-beetle Blaps mucronata 

 is no doubt another instance. There are also one or two wood- 

 feeding species which, if they were not directly imported with 

 timber, are very likely comparatively recent arrivals on the 

 island. The weevil Rhopalome sites Tardyi is an example : it lives 

 in the Ash and Sycamore trees planted round the castle, the only 

 trees on the island offering a suitable habitat for the species. 

 The Elder trees on the eastern side of the island are infested by 

 the wood-borer Caulotrypis czneopiceus, but whether the Elder 

 may not have been planted there is a question for botanists to 

 decide. It is possible, however, that both of these wood-feeders 

 reached the island by means of drifting timber/ 2 



With one possible exception the beetles found on Lambay 

 have all been previously recorded from Ireland. The following 

 species, however, have not been recorded from the county of 

 Dublin : — Falagria thoracica, *Homalota triangul 'urn , *H. ignobilis, 

 *Actobius cinerascens, *Lesteva punctata, *Choleva Wat soni and 

 Apion stolidmn. Four of these, indicated by asterisks, are new 

 records for the province of Leinster, and Homalota ignobilis, re- 

 corded with some reserve, is an addition to the Irish list. 



I am indebted to Dr. David Sharp, f.r.s., and to Mr. G. C. 

 Champion, f.z.s., for assistance in the identification of some of 

 the more critical species. 



1 Occurs also near Derry, No doubt it will be found in intermediate 

 localities in the north-east of Ireland. 



■ I once found Caulotrypis abundantly in a log of wood washed up on 

 the South Bull sands.
