An adult male of this species was sent me in May, 1892, by Miss 

 S. Smith., of Drogbeda, who bad taken it at Termonfeckan, Co. Louth, 

 while a pair (adult) were captured near Londonderry by Mr. J. N. 

 Milne (1895), in September, 1894, and an immature female was found 

 near the Upper Lake of Killarney, in July, 1898. The species, though 

 scarce, has therefore a fairly wide range in Ireland. In Great 

 Britain it has been found in Dorset, North "Wales, and Aberdeenshire, 

 but is uncommon. On the Continent it inhabits southern Norway 

 and Sweden, Belgium, north-eastern France, Germany, Austria, and 

 Hungary.
