Hydroporus erythrocephalus, Z. — Dumfries, Kirkcudbright, Wig- 

 town. 



H. rufifrons, Dufts. — Kirkcudbright, Maxwelltown L., Cargen Burn, 

 Dalbeattie ; not uncommon in a few spots, but extremely local. 



H. celatus, Clark. — Kirkcudbright, Criffel (Lennon). 



H. melanarius, Sturm. — Dumfries, Kirkcudbright ; a peat-moss 

 species occurring not uncommonly at all altitudes. 



H. memnonius, Nic. — Dumfries, Kirkcudbright, Wigtown ; not 



uncommon. 

 H. obscurus, Sturm. — Dumfries, Kirkcudbright, Wigtown ; a 



common peat-moss species.

H. discretus, Fairm. — Kirkcudbright, Maxwelltown L., Kirk- 

 connell, Lochfoot, Colvend, Dalbeattie ; not common. 



H. pubescens, Gyll. — Dumfries, Kirkcudbright, Wigtown ; probably 

 the most abundant species of the genus in the Solway district. 



H. planus, F. — Dumfries, Kirkcudbright; common on salt marshes 

 but not so common in other localities. 



H. lituratus, F. — Dumfries, Kirkcudbright. Occasionally on peat 

 mosses, but common on salt marshes. Fowler describes it as 

 an inhabitant of stagnant ponds, especially in woods. I have 

 never found it in woods, and in my experience it is common 

 on the west coast in salt marshes.

 Criffel (i); Dalbeattie L. (i); only three specimens. 



Agabus guttatus, Payk. — Kirkcudbright, Criffel, Bengairn, and 

 Screel ; probably common on high ground throughout the 

 district in clear burns.

 welltown L., Lochfoot, Colvend.
