 in company w.th Acilius sulcatus, Gyrinus natator, and G. minutus. 

 Unfortunately the exact locality where this rare insect occurred is 

 unknown, audit has not been met with since in Ireland. Dr. Shai^) 

 records it fron the Moray, Clyde, and Argyll districts of Scotland, 

 Northern Eui-ODe, "extending southwards in the mountains to the 

 Basses Alpes, md Northern Italy," and Siberia ('82 Sh.). It is

{^Sydatims transversalis, Berg. — In Mr. Haliday's MS. list, the 

 note on this spedes indicates that it was seen in the Tardy collection 

 by Mr. Haliday— but it is not included amongst the " certainly Irish " 

 species. There is an example in the Dublin Museum — formerly in 

 the collection oi Trinity College — marked as having been taken in 

 Ireland. This vas possibly taken by Tardy, but the species requires 

 confirmation as n,tive.]
