"Wicklow ("in first pond on road from Lara to Rathdrum — old 

 ponds now overgrown" H. MS.). — Clare (Lough Doon, Ht., coll. 

 m.).— Cork (Carrigaline, Ht., coll. Ws.).— Ireland (Fg. MS.). 



Rare; only two specimens have been found in this country in 

 recent years. One on the shore of Lough Doon, south Clare, by 

 Mr. Arthur Neale (June, 1895), and another in a pond near Car- 

 rigaline, by Mr. Dudley Westropp ; both of these specimens have 

 been presented by their captors to the Dublin Museum. From notes 

 in Mr. Haliday's MS. list, it is evident that the Wicklow specimens 

 were taken by the late Mr. J. Tardy, and were seen by Mr. Haliday 

 in the Furlong collection in 1849. The species occurs very locally in 

 the south of England, and Wales, and, according to Ganglbauer, it 

 ranges over central Europe, and the Mediterranean region.
