10. In cultivated fields near Tartaraghan, Armagh 

 (probably introduced with the crops) ; A. G. M., 1854. — 

 12. ToUymore Park, Down ; Mr. S. A, Stewart. The locali- 

 ties given for B. prcecox in the " Flora Belfastiensis," Mr. Tate 

 informs us, should be transferred to B. intermedia, which 

 appears to be rather common in the neighbourhood of Belfast, 

 having been found about Cave-hill Tramway; in fields at 

 Wolf -hill ; by the side of the Lagan ; and about Lisburn, on 

 railway banks, plentifully. In 1864 it occupied all the railway 

 banks from Derriaghy to Hillsborough, and occurred in great 

 profusion in borders of fields in the valley of the Lagan, 

 chiefly on a sandy soil. It was flrst gathered as {B. prcecox) 

 in fields near Ballymena, about the year 1836.
