8 The Irish Naturalist. January, 



Dublin Mollusca. 



While dredging at " The Pits," Kilbarrack, in June I brought in some 

 half-dozen specimens of the var. acuta of Limnaea auricidaria. Mr. Stelfox 

 informs me that he thinks this is a new locality, the old records coming 

 from more inland districts, but mentions some fossil shells taken by him 

 in an alluvial deposit of the Broad Meadow Water, west of Swords, in 

 1921 ; these also are var, acuta Jeff. 



Last June when collecting at Kilbarrack, in the field at the back 

 of the graveyard I found a dead sinistral shell of Helix aspersa Miill. Mr. 

 Stelfox to whom I showed it reports only one Irish record, ^ and he 

 possesses a living specimen taken in his garden in the summer of 1921.

Adalia bipunctata and other Ladybirds in Co. Cork. 



During the past summer I collected some La.dybird beetles, among 

 them being Adalia bipunctata L., identified by Mr. J. N. Halbert of the 

 National iNIuseum, a species for which a single specimen collected at 

 W^aterford by A. Neale and mentioned in Johnson and Halbert 's " List 

 of Beetles of Ireland " (Proc. R. I. Academy 1 900-1 902) is the only 

 previous Irish record, though a second specimen was taken in the same 

 place by Mr. Bonaparte W'yse in 1915. It occurred in some plenty 

 during 1922-1923 in my own garden, situated in East Cork, and this 

 year in a garden south of the River Lee (Mid-Cork). The t3-pical form 

 of this insect has red wing-cases with a single black spot on each, but 

 in the first-named locality I got several si)ecimen;s in which these colours 

 are reversed, the wing-cases being black with a red spot on each. This 

 variety has, apparentl}', not been previously noticed in Ireland. 



Other Ladybirds collected in the neighbourliood of Cork this year 

 are Coccinella vii-punctata L., C variabilis L., both widely distributed in 

 Ireland, and C. hieroglyphica L. which I found on a cliff at Courtmacsherry 

 (West Cork).

Dublin Insects. 



On September 29 while at Killiney Strand I caught an ant, which 

 proved to be a female Lasius niixtus Nyl., and is an addition to the Dublin 

 list. Mr. Stelfox had previously asked me to look for it, as he had 

 taken workers of an ant which he believed to be L. mixtiis but could not 

 be sure without seeing a female.
