 ■{ They are rather widely distributed 

 species in the southern counties of 

 .England, and also in S. Wales. 



Syromastes marg-lnatus, L.— Is probably frequent in the south- 

 \vest having been taken at Berehaven by Mr. G. H. Carpenter ; the 

 British distribution is similar to that of the two preceding species.

Oxytoelus uniglumis, L.— In great abundance on flowers of Cnicus 

 arvensis, at Castlefreke. 



Odyncrus trimarginatus, Zett — Not uncommon on heath (Erica) 

 at Ownahinchy and Tralong. All these specimens belong to a variety 

 with spotted tibiae. 



Sphecodes subquadratus, Sm. — New to Ireland. Taken at 

 Downeen, about burrows of Halictus rnbicundus. 



i These are also new Irish records, The 

 latter pretty and fragrant insect abounds 

 in the district and is a welcome addition 

 to our lists.
