{Continued from p. 152.) 



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. nigrita, F. Dumfries, Kirkcudbright, Wigtown; fairly common. 



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. 



H. obsoletus, Aube. Kirkcudbright, Cargen burn in flood ( i ) ; 



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. 



A. biguttatus, Ol. Solway (Lennon). 



A. paludosus, F. Dumfries, Lochar Moss ; Kirkcudbright, Max- 

 welltown L., Lochfoot, Colvend. 



A. uliginosus, Z. Dumfries, "Tinwald Downs," M'Nab, one 

 specimen Dublin Museum Coll.
