 Dublin (Portmarnock, '00 Ht. 3). 



On the sandy shore of Lough Neagh, and at Tynan on a somewhat 

 sandy place on the canal bank. As the canal comes from Lough 

 Neagh it is probable that the beetles were carried up in barges which 

 are often laden with sand from the lake shore at Maghery. At Port- 

 marnock the black form only was found.
